Worldwide, many species of primates are threatened with extinction due to habitat degradation, hunting, and climate change (habitat and climate combined threats, henceforth, "global change"). These threats work at different time scales, with hunting being the most immediate and climate change likely to have its fullest impact experienced from the present to a longer time frame. Lemurs are a type of primate found only on Madagascar, an island experiencing rapid global change, which puts lemurs at a heighted risk of extinction. My dissertation research focused on the critically endangered golden-crowned sifaka (Propithecus tattersalli; hereafter, "sifaka"), a species of lemur found only in a few isolated forests across a dry to wet gradient in northeastern Madagascar. To better understand their extinction risk, I conducted surveys to estimate the number of sifakas remaining and investigated several factors that might determine how many sifakas can live in one place. I then explored how sifaka diets varied depending on the forest type that they inhabit and tested whether nutrients in their food might determine sifaka numbers. Lastly, I calculated sifaka genetic diversity to assess their ability to adapt to new environmental conditions and to determine whether sifakas can move across the landscape to find new mates and to potentially colonize new areas of habitat. Sifaka densities varied widely across their range (6.8-78.1 sifakas/km2 ). Only 10,222-12,631 sifakas remain, which is 30-43% less than the range of estimates obtained 10 years ago (~18,000 sifakas). Tree cutting, normalized difference vegetation index (NDVI; a measure of plant health or "greenness" obtained from satellite data), and a tree species diversity index were useful measures to predict sifaka densities. Sifakas ate different plant parts (buds, flowers, fruits, seeds, and leaves) from over 101 plant species. The amount of time they spent eating each day varied by the time of year, forest type, and sex. On average, they spent a quarter of their day eating. Magnesium and potassium concentrations in sifaka food items also were useful nutrition-related measures to predict sifaka densities. Genetic analyses suggested that sifaka populations are becoming more isolated and inbred, meaning sifakas are breeding with other sifakas to which they are closely related. However, it appears that sifakas still can move between forest patches to find new mates and to potentially colonize new areas, if such areas are created. Further validation of these genetic results is needed. I also identified critical areas that will be important to protect and reforest to ensure that movements between populations can continue.

Full textTo evaluate the conservation of the brown howler monkey in buffer zone of the Itapuã State Park were performed in the District of Itapuã, Viamão/RS, a survey of occurrence, a survey of the existing conflicts between humans and howler monkeys, and a study of environmental perception to investigate how the community relates to the species. This information is relevant to ensure the future viability of populations in Itapuã State Park. It was found that the brown howler monkey is still present in 96.4% of the quadrats sampled, and that the forest cover is the main factor for the occurrence of the species. There is still a relative connectivity between forested areas, which allows the dispersion of individuals. Apparently there is a metapopulation type "population patch" in the District of Itapuã. The high value of occurrence found in this study may be indicating that the habitat may be being a limited resource. Despite this positive scenario, conflicts occur between the howlers and the human population, and these conflicts may affect the conservation of the species through an increase in mortality. The main types of conflict are electrocution, attack dogs and road kill. Actions are suggested to minimize these conflicts and allow for peaceful coexistence between humans and apes. The human population of the District of Itapuã has a rather positive view on the monkey, and is quite tolerant to the presence of this species. This certainly affects the conservation of the species in a positive way. There is also a favorable view, but to a lesser degree, with respect to Itapuã State Park. Despite a certain unknown, the area's importance is recognized by the community.

Ao longo dos anos humanos tem transportado espécies de forma proposital ou despercebida para fora de sua área natural. Espécies introduzidas podem trazer prejuízos ambientais e econômicos e são a segunda principal causa de perda da biodiversidade, sendo apenas superada pela supressão de ambientes. Os primatas sempre mantiveram uma relação muito estreita com os seres humanos facilitando com que fossem transportados para fora de seus limites naturais. A espécie Callithrix penicillata ocorre tipicamente no cerrado e é relatada como invasora em diversos estados do país, suas populações introduzidas tem se tornando um problema para a conservação devido a seu alto potencial de ocupação, predação de fauna nativa competição com congêneres nativos e hibridização. Para iniciar ações de manejo é preciso conhecer os locais já invadidos e os possíveis de invasão. Neste sentido a modelagem de distribuição potencial (MDP) baseada nos modelos ecológicos de nicho, tem se demonstrado uma maneira rápida, confiável e com baixo custo para identificar áreas com maior probabilidade de ocorrência de uma espécie. Neste estudo utilizamos a modelagem de distribuição potencial (MDP) para identificar áreas com maior probabilidade de ocorrência de uma espécie, através do software Maxent (Máxima Entropia). Este trabalho tem como objetivo principal conhecer o potencial de invasão da espécie Callithrix penicillata no território brasileiro. E como objetivos específicos conhecer a distribuição atual do sagui C. penicillata e confrontar com aquela encontrada na literatura, conhecer as áreas mais suscetíveis à invasão e discutir o problema que a introdução dessa espécie vem causando nas regiões onde é uma espécie invasora. O valor encontrado foi de AUC=0.966 para dados de treino e AUC=0.919 para os dados de teste, com valor da curva bem próximo a 1. Pelo teste Jackknife, observamos que a variável mais correlacionada a distribuição foi a sazonalidade da temperatura (AUC = 0,86), coincidindo com outros estudos que demonstram que variáveis climáticas influenciam a distribuição de primatas. As regiões mais apontadas como susceptíveis a invasão foi a Floresta Atlântica da região Sudeste seguida pelo Sul. A Floresta Atlântica por possuir alto nível de endemismo, e as regiões Sul e Sudeste por terem maior concentração demográfica, contribuem para que a invasão biológica dos saguis se torne um fator preocupante.
Over the years humans have transported species purposeful or unnoticed out of its natural range. Introduced species can bring environmental and economic damages and are the second leading cause of biodiversity loss, being surpassed only by suppressing environments. Primates have always maintained a very close relationship with humans facilitating them to be transported out of their natural limits. The Callithrix penicillata species typically occurs in the cerrado and is reported as invasive in several states of the country, its population has made becoming a problem for conservation because of its high potential for occupation, native wildlife predation and competition with native hybridization counterparts. To initiate management actions we need to know the locals already invaded and possible invasion, thus the potential distribution modeling (MDP) based on ecological models niche, it has proved a fast, reliable and cost to identify areas with greater probability of some sort. In this study we used the potential distribution modeling (MDP) to identify areas with higher probability of occurrence of a species through the Maxent software (Maximum Entropy). This work aims to know the invasion potential of the species in Brazil. And the following objectives know the current distribution of C. penicillata marmoset and confront with that found in the literature, know the areas most susceptible to invasion and discuss the problem that the introduction of this species has caused in the regions where it is an invasive species. The value found was AUC = 0.966 for training data and AUC = 0919 for the test data with the value very close to curve 1. At Jackknife test, we found that the most correlated variable distribution was seasonality temperature (AUC = 0, 86), coinciding with other studies showing that environmental factors influence the distribution of primates. The most frequently mentioned site susceptible to invasion was the Atlantic Forest of the Southeast region followed by the South. The Atlantic Forest for having high levels of endemism, and the South and Southeast regions to have higher population concentration, contribute to the biological invasion of marmosets are become a concern.

Full textTutkimukseni käsittelee Yhdysvaltain republikaanipuolueen esivaaliehdokkaiden väittelyretoriikkaa. Aineistoni koostuu viidestätoista (15) väittelystä vuosien 2008 ja 2012 esivaaleissa. Tutkin, miten republikaanipuolueen ja amerikkalaisen konservatismin välinen suhde näyttäytyy ehdokkaiden retoriikassa. Amerikkalainen konservatismi liitetään usein republikaanipuolueeseen, ja mielipidemittausten mukaan noin 70 prosenttia republikaaneista pitää itseään konservatiiveina. Esivaalit saavat suurta kansallista ja kansainvälistä huomiota, ja väittelyitä seuraavat miljoonat tv-katsojat. Esivaaliväittelyillä on tärkeä rooli puolueen agendan ja poliittisen ideologian määrittelyssä. Sillä, miten republikaanipuolue määrittelee ideologiansa ja agendansa on suuri merkitys koko Yhdysvaltain poliittiselle järjestelmälle. Yhdysvallat on kiistatta maailman merkittävin suurvalta, ja jos republikaanien edustaja valitaan Yhdysvaltain presidentiksi, puolueen agendan merkitys laajenee käsittämään entistä vahvemmin myös kansainvälisiä asioita. Amerikkalaisen konservatismin rooli republikaanipuolueessa on tärkeä ja ajankohtainen aihe, joka kaipaa tutkimusta. Tutkimani esivaalikampanjat ovat tärkeitä niin poliittisesta kuin historiallisesta näkökulmasta. Vuonna 2008 Yhdysvallat joutui rankimman talouskriisin kouriin sitten 1930-luvun Suuren laman. Lisäksi republikaanipresidentti George W. Bushin kaksi kautta olivat traumaattisia amerikkalaisen konservatiiviliikkeen yhtenäisyydelle. Republikaanit hävisivät vuoden 2008 presidentinvaalit, ja demokraatti Barack Obaman valinta herätti kysymyksen republikaanipuolueen tulevaisuudesta sekä amerikkalaisen konservatiiviliikkeen yhtenäisyydestä. Tutkimukseni on monitieteistä, ja hyödynnän gradussani niin historiantutkimuksen kuin kielitieteen menetelmiä. Tutkimukseni on laadullista, ja analyysini pohjautuu esivaaliväittelyistä poimittuihin katkelmiin. Etsin aineistosta kohtia, joissa ehdokkaat viittaavat tavalla tai toisella konservatismiin. Tämän jälkeen pyrin selittämään viittausten merkityksen ja tarkastelemaan niitä laajemmassa historiallisessa ja poliittisessa kontekstissa. Konservatismin määritelmien tutkimisen lisäksi tarkastelen esivaaliehdokkaiden käyttämiä retorisia strategioita ja suostuttelun ja taivuttelun keinoja. Lisäksi vertaan esivaalikampanjoita toisiinsa ottaen huomioon mahdolliset eroavaisuudet sekä kehityksen. Tutkimukseni osoittaa, että amerikkalainen konservatismi nähdään republikaanipuolueen sieluna, ja siitä keskustellaan aktiivisesti esivaalikampanjoiden aikana. Ehdokkaat korostavat konservatismin merkitystä retoriikassaan ja pyrkivät esittämään itsensä joukon vankkumattomimpana konservatiivina. Näkyvästä roolistaan huolimatta amerikkalaisen konservatismin määritelmä on hyvin epäselvä, ja puolueen sisällä on selkeitä ristiriitoja siitä, mitä konservatismi ylipäätään on. Sisäiset ristiriidat ovat selkeästi esillä vuosien 2008 ja 2012 esivaaliväittelyiden retoriikassa

Full textO guigó de Coimbra-Filho (Callicebus coimbrai Kobayashi & Langguth, 1999) é um primata ameaçado de extinção, porém é uma espécie pouco conhecida e habita fragmentos de Floresta Atlântica no Estado de Sergipe e Bahia (litoral norte). O objetivo deste trabalho foi avaliar os efeitos da fragmentação de habitat sobre suas características ecológicas, trazendo informações sobre densidade, tamanho populacional e características básicas da ecologia dentro da área de estudo. Esses dados também foram coletados para outras espécies de primatas. O trabalho foi realizado na Fazenda Trapsa, no sul de Sergipe, onde duas técnicas de levantamento foram aplicadas - playback (fragmentos < 50 ha) e transecção linear (fragmentos > 50 ha). Foi percorrido um total de 476,1 km entre abril a outubro de 2008. Densidade populacional foi estimada através do programa DISTANCE e pelo método de Kelker. A densidade também foi calculada diretamente das contagens de grupos. Um total de 12 grupos foi identificado nos quatro maiores fragmentos levantados. Grupos de Cebus xanthosternos e Callithrix jacchus também foram observados em todos os quatro fragmentos. A presença de Callicebus nos dois fragmentos menores foi confirmada por playback. A densidade geral nos quatro fragmentos maiores foi de 12,6 indivíduos por km2. Tanto o DISTANCE quanto o Kelker forneceram super-estimativas de densidade. Os resultados do presente estudo indicam a necessidade de cautela na avaliação e comparação de estimativas de densidade de guigós, como também reenfatizou a eficiência de métodos alternativos para o levantamento de populações de guigós em fragmentos pequenos. A Fazenda Trapsa parece abrigar uma população de 50 guigós, que pode ter boas chances de sobreviver a longo prazo, principalmente se algumas medidas de conservação forem tomadas. Os resultados do estudo reforçam a necessidade para o estabelecimento de uma rede de reserva, e o desenvolvimento de estratégias de manejo metapopulacional ativo, a fim de garantir a longo prazo possibilidades para sobrevivência de C. coimbrai.

Full textUnderstanding survival and breeding season length of game birds are important for effective management and conservation. By determining the variables that drive survival and recovery rates for white-winged doves (Zenaida asiatica), I can offer management implications to agencies across their range. There is currently little knowledge about white-winged dove molting and hatching chronology. The objectives of this study were to: 1) investigate annual survival and recovery rates of white-winged doves, 2) determine intrinsic and extrinsic factors influencing them, 3) determine AHY primary feather molt rate and the factors that influence molt rate and initiation, and 4) describe hatch chronology and determine the factors that influence hatching. To understand what influences annual survival and recovery, I examined subpopulation, climate variables, urbanization characteristics, molt, and band type as covariates. I used the Brownie approach in the RMark package of R to compare annual survival and recovery models and generate estimates. I used Underhill and Zucchini models in the Moult package of R to determine AHY primary feather molt rate and the best predictors of molt rate and initiation. I analyzed molt scores of HY doves recorded during annual banding using GLMs in R to determine the factors that influence hatching. I used AIC to select the most parsimonious models for each a priori candidate set. I analyzed 71,675 bands, of which, 3,086 were recovered from 2007 – 2016. My most supported model influencing survival and recovery was [S(age class x urban intensity) f(age class X MRPP)]. Average AHY primary molt rate across Texas was 13.21 ± 0.93 days. MRPP subpopulation + Year was the most supported model influencing AHY primary molt rate, AHY molt initiation, and hatch date. Within my sample, 95% of AHY white-winged doves began molting from 7 April to 8 July and completed molt 17 August to 17 November. White-winged doves hatched as early as 6 January and as late as 27 July, with 95% of all hatching occurring between 22 March and 18 June and peaking at 5 May. Urban intensity was an important variable influencing annual survival, which is expected for such an urbanized species. MRPP subpopulations influenced vital rates and should be considered for future harvest management.

Full textCapuchin monkeys are frugivorous-insectivorous primates, although they can explore a wide range of food items. The availability of fruits is a key-aspect of the ecology of these primates, with direct influences over the quality of a given area for the species, and often represents the main determinant of the pattern of range use of groups. In a population-level analysis, however, the pattern of occupation of a fragment by capuchin monkeys is influenced by a broader set of factors, including structural parameters of the habitat. The purpose of this study was to describe the pattern of use of different phytophysiognomies by a population of yellow-breasted capuchins in an Atlantic Forest fragment, relating to the structural aspects and fruit availability of the environment. The study area is in Itaporanga D'Ajuda (11º08'07 "S, 37º18'43" W), in the state of Sergipe, henceforth denoted by Fazenda Rio Fundo (FRF). The fragment has approximately 800 ha of native forest, associated with surrounding plantations of Eucalyptus sp. and bamboos. Among the native forest formations, the vegetation types of shrub-arboreal Restinga (RE), Mata de Tabuleiro (MT), and arboreal Restinga (mature, FM, and secondary, FS). Data collection was carried out monthly between March 2015 and February 2016. The different habitat types of the FRF were compared in relation to the availability of fruits, through phenological monitoring of tree species; and habitat structure, by analyzing its medium height, DBH, density, land cover rate and species composition of the tree community. The use of different habitats by capuchin monkeys, and the occurrence of potential predators of the species, was monitored using 31 camera traps, distributed among habitats. The FM and the FS are the habitats with greater height of canopy and ground cover rate at FRF, in addition to having a pattern of relatively continuous availability of fruit throughout the year. The areas of RE and MT, in turn, are the habitats with the highest dominance indexes in the plant community, as well as the most open and seasonal ones. From a sampling effort of 1,444 trap-day, capuchin monkeys were recorded in 430 videos in 39 separate visits. Nine of the 10 permanent sampling points in FM or FS received visits of the target-species. No record of the presence of monkeys was obtained in MT or RE. We observed that the areas of FM and FS represent preferential habitats for the yellow-breasted capuchins at FRF. This preference is related to the greater height of canopy and ground cover rate of these areas. The advantages conferred by these parameters refer to both the availability of food and support for the locomotion of the primates, and thus, protection against predation. The main threat faced by the population of S. xanthosternos at FRF refers to its limited size, which in turn, stems from the small size and high degree of isolation of the fragment. The presence of several small remaining fragments in the region, however, enables the creation of ecological corridors, which would increase the total area available for the maintenance of the yellow-breasted capuchins, contributing to the conservation of populations of the species in the state.
Macacos-prego são considerados frugívoros-insetívoros, apesar de explorarem uma vasta gama de recursos alimentares. A disponibilidade de frutos é um aspecto-chave da ecologia desses primatas, influenciando diretamente na qualidade da área para as espécies, além de frequentemente ser o principal determinante do padrão de uso da área de vida dos grupos. Numa análise em nível populacional, entretanto, o padrão de ocupação de um fragmento por macacos-prego pode ser influenciado por um conjunto mais amplo de fatores, o que inclui parâmetros estruturais do habitat. O objetivo do presente trabalho foi descrever o padrão de uso de diferentes fitofisionomias por uma população de Sapajus xanthosternos num fragmento de Mata Atlântica, relacionando-o a aspectos estruturais e de disponibilidade de frutos do ambiente. A área de estudo fica no município de Itaporanga D’Ajuda (11º08’07”S, 37º18’43”W), no estado de Sergipe, doravante tratado por Fazenda Rio Fundo (FRF). O fragmento possui cerca de 800 ha de floresta nativa, associados a plantações de Eucalyptus sp. e bambus. Entre as formações florestais nativas, estão as fitofisionomias de Restinga arbustivo-arbórea (RE), Mata de tabuleiro (MT), e Restinga arbórea madura (FM) e secundária (FS). A coleta de dados foi realizada mensalmente entre março de 2015 e fevereiro de 2016. Os diferentes tipos de habitat da FRF foram comparados entre si em relação à disponibilidade de frutos, através do monitoramento fenológico de espécies arbóreas; e à sua estrutura, através da análise de seus valores médios de altura, DAP, densidade, taxa de cobertura do solo e composição florística de indivíduos arbóreos. A utilização dos diferentes tipos de habitat pelos macacos-prego, além da ocorrência de potenciais predadores da espécie, foi monitorada através de 31 armadilhas fotográficas, distribuídas entre os habitats. A FM e a FS são os habitats com maior altura de dossel e taxa de cobertura do solo da FRF, além de apresentarem um padrão de disponibilidade de frutos relativamente contínuo ao longo do ano. As áreas de RE e MT, por sua vez, são os habitats com os maiores índices de dominância na comunidade vegetal, e também os mais abertos e sazonais da FRF. De um esforço amostral de 1.444 armadilhas-dia, o macaco-prego foi registrado em 430 vídeos, em 39 visitas independentes. Nove dos 10 pontos amostrais fixos em FM ou FS receberam visitas da espécie-foco. Não foi obtido nenhum registro da presença dos macacos em MT ou em RE. Foi observado que na FRF as áreas de FM e FS representam habitats preferenciais para os macacos-prego-do-peito-amarelo. Essa preferência parece estar relacionada à maior altura de dossel e taxa de cobertura do solo dessas áreas. As vantagens conferidas por esses parâmetros referem-se tanto à disponibilidade de alimento, com à de suportes para a locomoção dos macacos e, por conseguinte, proteção contra predação. A principal ameaça enfrentada pela população de S. xanthosternos da FRF refere-se ao seu tamanho limitado que, por sua vez, decorre do tamanho reduzido e alto grau de isolamento do fragmento. A presença de vários pequenos fragmentos remanescentes na região, entretanto, possibilita a criação de corredores ecológicos, o que aumentaria a área total disponível para a manutenção do macaco-prego-do-peito-amarelo, colaborando para a conservação das populações da espécie do estado.

Nesta tese tive o objetivo de investigar os fatores relacionados ao risco de extinção em primatas, assim como as tendências e vieses nos esforços de pesquisas voltadas para a conservação do grupo. No primeiro capítulo, por meio de uma cienciometria, mostrei quais são os temas, abordagens e espécies mais estudadas, bem como as instituições e locais que mais realizam esses estudos. Demonstrei que os esforços de pesquisa com conservação de primatas não têm sido motivados pelo status de conservação das espécies e tamanho da sua distribuição, e sim pelo peso corporal e idade (tempo desde a sua descrição). No segundo capítulo, testei se a dieta de primatas pode predizer o risco de extinção das espécies, mensurando dieta de diferentes maneiras: amplitude de dieta, diversidade de dieta, tipo de dieta e disparidade de itens. Concluí que a dieta prediz o risco de extinção, mas apenas pela métrica de disparidade de itens, sendo que espécies capazes de consumir itens mais diferentes entre si estarão menos propensas à extinção. No terceiro e último capítulo, avaliei os padrões de risco de extinção em primatas. Incluí variáveis intrínsecas e extrínsecas em modelos que particionam a variância em componentes espaciais, filogenéticas e independentes. Mostrei que espécies próximas na filogenia e no espaço tendem a apresentar status de ameaça semelhantes. Além disso, encontrei que a região Madagascar é a pior para os primatas e que o tempo de desmame, tamanho da distribuição geográfica e fatores como “human footprint” e pobreza humana influenciam no risco de extinção das espécies. Por fim, demonstrei que o espaço possui grande influência no risco de extinção de primatas, não devendo ser ignorado nesse tipo de análise.

Full textPrimaries: A Dress Rehearsal for the General Election? Since the selection of party leaders in a decentralized manner is a recent phenomenon in Canada, how is this new selection procedure different from an election campaign? This project is a study of a current case, the leadership selection of the Conservative Party of Canada. The research question is: How do the rules of the Conservative Party of Canada’s 2016-2017 leadership race influence the electoral prospect of the party? It is answered using an analysis of media content, data from social networks, and semistructured interviews. Michels’ (1915c) Iron Law of Oligarchy suggests that due to the lack of interests of voters, parties have centered their increasingly complex organizations around leaders. Three components lead to the oligarchization of political parties in democracies: the psychology of candidates; the need for organization; and the psychology of the masses (Michels, 1915c, 516). This project updates and tests the Iron Law. The Conservative Party of Canada’s leadership campaign is not a dress rehearsal for the general election. This leadership primary is more like an audition. It is about choosing who will be the key players at the election, no dress rehearsal needed. It is about setting the scene, writing the plot and choosing who will lead the party at the dress rehearsal. Which will really begin during the policy convention that follows the leadership selection in the summer of 2018.

ENGLISH ABSTRACT: The We Care Primary project is a participatory materials development research project, grounded through a socio-historical location of the research question in the assumptions and ideals of the critical inquiry paradigm and socially critical environmental education. This research represents an atlemptto clarifY the assumptions and orientations of socially critical environmental education as a possible 'tangible alternative' to modernist models of environmental education and educational change in a South African context. Through this project environmental education materials development emerged as a reflexive and responsive process of change in which I was able to work with teachers with in local contexts to develop resource materials which may contribute to the development of quality education and the transformation of the junior primary school phase. The emerging central thesis of this report is an ongoing questioning of the notion of participation, and a realisation of the complexities of establishing conditions for authentic participation in materials development, curriculum development and research contexts, Phase one of this research report describes a journey of inquiry toward" socially critical environmental education. This phase portrays a growing understanding of environmental education and is focused on the development of a participatory orientation to materials development. Phase two of this research journey illustrates a critical and reflexive stance to the 'weaknesses' identified in the first phase of the project. The interdependence of curriculum development, materials development and in service teacher education is explored. This phase of the research is presented as a journey with in socially critical environmental education and reflects ongoing praxis and engagement with in the assumptions of critical theory and socially critical environmental education. In phase two and three, the development of a critically reflexive stance to the assumptions guiding this study is described, and a shift in possible research orientations is highlighted. Further possibilities for research journeys beyond socially critical environmental education are presented in phase three through a tentative critique of the first two phases of this research project. This research report offers a brief insight into some of the complexities of change in the formal education sector. It demonstrates that confronting the challenges and complexities of change in realistic and meaningful ways is possibly one of the most daunting realities facing South Africans as we begin to respond to the many legacies of apartheid ideologies, modernisation, a history of mis-education and poor education, decades of social separation and increasing socioecological degradation and risk.

Full textThis thesis arises as a response to the main welfare problems that can affect most animals living in zoos and aquariums. In particular, it has been driven by concern about the complexity involved in keeping great apes in optimal conditions. In this context, the overall objective of this work is to search evaluation models that may help to improve or complement the existing action and conservation plans intended for western lowland gorillas (Gorilla gorilla gorilla) in captivity. With this aim, an observational study on samples of western lowland gorillas has been carried out in two institutions: the Barcelona Zoo and the Apenheul Primate Park (the Netherlands). A total of 303 hours of recordings have been analyzed spread over 5 mixed groups (4 in Barcelona and 1 in Apenheul) and a single dominant male. A cross-sectional comparison between groups, treating each one as a case, has been carried out, as well as an intragroup assessment within a family group along its various stages (pre-post comparison). Later, our findings have been compared with those of the previous literature. No significant differences have been found between the results obtained in the High Frugivory (HF) season and the groups studied. This would confirm that the complexity of naturalized areas, social groups and the management offered by the two zoological institutions, can ensure the opportunities involved in the performance of patterns of activity quite similar to those observed in the natural environment. Neither do we found significant differences between the spatial proximity index between individuals and patterns of behavior and proxemics. This would suggest that the available space for our groups, does not compromise the welfare of the gorillas studied. In summary, the results of this study confirm the importance of social composition and density in groups of western lowland gorillas in captivity. Likewise, these factors may serve as good indicators of their welfare. Indeed, the composition of family groups stables in time, with variability of social classes and a social density appropriate to the quality and the facilities available, is essential to achieve success in the ex situ conservation of this species. At the same time, the previous history of the individuals and the role exerted by dominant males play a fundamental role in the formation and cohesion of these groups.

From a group of 100 children, 60 subjects were selected on the basis of failure to conserve as measured by Piagetian conservation tasks. One of the conservation tasks was employed for training the subject to be able to conserve. A pre-test/post-test experimental design was used in a six phase experiment; assessment of possession of conservation concepts through the aid of Piagetian tasks of conservation of substance, weight, number and length; assessment of intelligence with the aid of the New South African Individual Scale; assessment of mental ability using the Draw-a-person test; group training with different methods of teaching on length conservation; immediate post test to determine effectiveness of training and transfer to other tasks and a delayed post-test to four weeks after training to assess retention of training effects.

Resumo: As características de fragmentos florestais e seu contexto podem contribuir para a manutenção de populações de primatas, assim como mudanças na paisagem ao longo do tempo podem alterar sua distribuição. O objetivo deste trabalho é identificar se características de fragmentos florestais e seu contexto na paisagem são determinantes na distribuição de Alouatta clamitans bem como relacionar padrões de mudanças na paisagem ao longo do tempo com a distribuição da espécie, em uma grande cidade no sul do Brasil (Porto Alegre, RS). Dados de presença e ausência da espécie foram obtidos na região de estudo em quadrículas de 25 ha. Os dados de quadrículas foram convertidos para presença/ausência de bugios nos fragmentos florestais. As variáveis (área, forma, isolamento, antropização, distância de via e de urbanização) foram obtidas por ferramentas de geoprocessamento para os 214 fragmentos. Para a análise da distribuição temporal da espécie, a presença/ausência de bugios em 65 quadrículas foi comparada em dois momentos no tempo (1995 e 2010). Obtivemos variáveis de mudança na paisagem através de ferramentas de geoprocessamento, com base em fotografias aéreas e imagens de satélite. Os fragmentos de mata com bugios são em menor número, mais conectados e estão em contexto menos antropizado. Em 63% das quadrículas houve persistência de bugios, em 3% desaparecimento, em 26% colonização e em 8% manutenção de ausência. As mudanças ocorridas na paisagem não estão diretamente relacionadas com a variação na distribuição da espécie. Os bugios estão distribuídos em boa parte dos remanescentes florestais do município, em fragmentos grandes, conectados e em contexto menos antropizado e se mantém, pelo período de 15 anos, num mosaico de paisagem com fragmentos florestais em contexto predominantemente rural
Abstract: Forest fragment characteristics and context may contribute to the persistence of primate population, as well as landscape alteration in time can change their distribution. Our objective is to identify which are those forest fragments and context characteristics that determine the distribution of Alouatta clamitans and also relate landscapes changes in 15 years time with changes in the species distribution in Porto Alegre, RS. The species has been recorded in the municipality in 25 ha squares. Howler monkey presence or absence data in squares were transposed to forest fragments. Areas, shape, isolation, anthopization and distances from roads and urban areas were obtained by geoprocessing tools. Sixty five squares were visited twice, in 1995 and in 2010 to verify changes in howler monkey distribution. Landscape change analysis was made by geoprocessing tools based on aerial photos and satellite images. There are more fragments with howlers' presence than without, and they are also larger, less isolated and in context less anthropized than those where howlers were absent. In 63% of the squares howlers persisted, in 3% they disappeared, 26% were colonized and kept absent in 8%. There were little changes in the landscape, and they're not related to changes in howlers' distribution. Landscape mosaics, with natural and rural areas seem to contribute to the occurrence, and persistence, of the species. Conservation strategies should keep large and connected areas in predominant rural landscapes

Full textIn the encyclopaedia by diderot, d'alembert and jaucourt, politics is on principle submitted to morals. But this principle, engendered by fear of despotism, is surreptitiously substituted by another, this time generated by the wish to make politics into a subject of scientific knowledge : the principle of the primacy of the natural law of self-preservation. That principle, inherited from hobbes and the jurisconsults is not easily compatible with morals. Yet diderot, and to a certain extent jaucourt, attempts to endow self-preservation with an altruistic dimension in order to reconcile natural law with morals. Does he fear that the rational excresence on politics, the economical science, may forge a reducing picture of man which could provide the power with other means of alienation? in fact, the fascination which the rigour of exact sciences exerts on a "science de l'homme" like the political science, leads to the elaboration of a schematic concept of human nature, characterized by an excessive "self-respect" which the political philosophy of the encyclopaedia partly contests. Thus the encyclopaedic discourse, a favourable place for systematization, emphasizes the confrontation of politics, morals and reason

Both an unprecedented drought and a population increase have brought about an important deforestation of a terricrust table and have provoked a widespread run off which was progressively destroying the cultivable soils below. In this dusadventaged context, the hydric erosion stabilization represent a main objectif for water and soils conservation in sine saloum southern zone : through the run-off control at the hight sides level by means of pervious micro dams and the humus reformation. Here, we focus on the protective improments on the environment's structure and functioning at an integrated scale of keur dianko-sonkorong catchment basin. We've tested 3 techniques of improvments according to the environment biophysical and socioeconomical contraints : on one hand we've protected high sides of the residuel ferricrust table with a stony cordon, on the other hand we've structured the cultivated spaces with contour quickset hedges. Presents results show the possibility to act effectively on the main elements of erosion, by improving the environment structure and functionong. We can learm among all these lessons that : the ligneous stratum evolution is conveyed by a 50% rise of the species, a doubling or more of the population density. The aerial and herbaceous phytomass is 1,5 to 3 times than the check plots of land. The run-off's measurements demonstrate that the flow on the defens is 3 times is 3 times inferior to the check. The quickset-hedges help to water conveys'reduction and to percolation increase with the hydrous profite betterment over 4 m away on either side of the small shurbes.

The main goal of any captive breeding program consists is maximizing the conservation of genetic diversity. Groups kept in captivity are particularly susceptible to the loss of genetic diversity, inbreeding depression and adaptation to captivity, due to their small size. The genetic characterization of wild and captive populations is an important tool both to minimize these impacts and for the conservation of these species, since it enables the development of management strategies aimed at maintenance of genetic diversity. In this context, the main objective of the study was to evaluate genetic variability and paternity for animals of black lion tamarin from Centro de Primatología do Rio de Janeiro, Fundacão Parque Zoológico de Sao Paulo, Parque Ecológico de Sao Carlos and 14 specimen belonging to the Durrell Conservation Trust in England using 15 microsatellite loci. The results of the allelic richness and expected heterozygosity showed similar values of alleles numbers and heterozygosity when compared with other species of Callitrichidae. Factorial correspondence analysis (FCA) showed greater homogeneity among captive animals than wild animals from Capão Bonito. The captive groups showed no differentiation among them and high differentiation from the wild Capão Bonito population. The data obtained herein are fundamental to increase the knowledge in genetic aspects of tamarins and support breeding programs to prevent loss of genetic diversity and inbreeding.
Maximizar a conservação da diversidade genética é um dos principais objetivos de qualquer programa de reprodução em cativeiro. Por serem de pequeno tamanho, grupos mantidos em cativeiro são particularmente suscetíveis à perda de diversidade genética, depressão endogâmica e adaptação ao cativeiro. Na tentativa de minimizar tais impactos, a caracterização genética de populações de vida livre e de cativeiro, torna-se uma importante ferramenta para a conservação destas espécies, uma vez que possibilita o desenvolvimento de estratégias de manejo que visem à manutenção de níveis adequados de diversidade genética. Neste contexto o objetivo principal deste trabalho foi avaliar através de 15 loci microssatélites, os níveis de variabilidade genética e paternidade dos animais mantidos em cativeiro no Brasil, no Centro de Primatologia do Rio de Janeiro, Fundação Parque Zoológico de São Paulo, Parque Ecológico de São Carlos e 14 espécimenes que faziam parte do Durrell Conservation Trust na Inglaterra. Os resultados referentes à riqueza alélica e heterozigosidade esperada mostraram que há uma representação similar nos valores de alelos e heterozigosidade quando comparado com outras espécies de Calitriquídeos. A análise de correspondência fatorial (FCA) mostrou que os grupos em cativeiro do Brasil apresentaram maior homogeneidade, quando comparados a um grupo de vida livre proveniente da região de Capão Bonito (São Paulo) e aos 14 indivíduos que representam ao grupo em cativeiro do zoológico de Durrell. O alto grau de parentesco entre os animais em cativeiro evidencia baixa diferenciação entre os grupos pertencentes às diferentes instituições brasileiras estudadas. Os grupos de cativeiro do Brasil, no entanto, mostraram-se divergentes dos animais de Capão Bonito. As informações obtidas neste trabalho são fundamentais para aumentar o conhecimento sob aspectos genéticos dos micos-leões-pretos e subsidiar planos de reprodução assistida que visem minimizar a perda de diversidade genética e a endogamia.

Full textA introdução de espécies em locais fora de sua distribuição natural é uma preocupação importante na conservação da biodiversidade. A espécie Callithrix aurita é endêmica das regiões de floresta de altitude da Mata Atlântica do Sudeste do Brasil. Os critérios mais relevantes que a enquadram como espécie ameaçada de extinção são: destruição do habitat, incapacidade de adaptação a florestas secundárias degradadas, declínio populacional, distribuição restrita e introdução de espécies exóticas invasoras. Estes critérios, aliados à evidente raridade, explicam a sua inclusão na Lista Oficial de Espécies da Fauna Brasileira Ameaçadas de Extinção. Os objetivos do trabalho são: estimar o tamanho populacional de C. aurita, C. penicillata e seus híbridos no Parque Nacional da Serra dos Órgãos, avaliar a hibridação entre as espécies por caracteres morfológicos e laboratoriais, verificar o estado de saúde e confirmar a participação de C. aurita na paternidade dos animais capturados, propor um plano de erradicação e de controle de invasão de C. penicillata no Parque. Os tamanhos populacionais das duas espécies de primatas foram estimados através do método Distance Sampling. Um total de sete sagüis foi capturado com armadilhas de captura viva para a contenção física e química e posterior realização dos procedimentos. Para o hemograma, as dosagens bioquímicas e as análises genéticas, o sangue foi recolhido em um tubo de ensaio contendo anticoagulante e mantido em temperatura de refrigeração até o momento da manipulação / processamento das amostras. Callithrix aurita parece estar bem preservada apenas na área do Parque correspondente ao trecho situado no município de Petrópolis. As análises citogenéticas e moleculares dos híbridos são uma ferramenta útil para confirmar se há ou não hibridação, identificando as espécies envolvidas e verificando se há tendência nos retrocruzamentos. Pode-se sugerir que existe uma tendência à diferenciação das espécies e identificação de indivíduos híbridos pelo padrão hematológico e bioquímico, a ser confirmada com uma amostragem maior de animais da espécie C. aurita, preferencialmente da mesma localidade e nas mesmas condições. No caso de C. aurita, as principais recomendações para sua conservação incluem pesquisas para o registro de outras populações em áreas de distribuição livres de invasão, para que se possa avaliar as chances de recuperação populacional e sobrevivência da espécie. A criação de novas Unidades de Conservação deve ser estimulada, assim como estudos mais aprofundados sobre a espécie nos locais já conhecidos de ocorrência, além de um programa seguro de criação em cativeiro.
The introduction of species in places outside their natural distribution is an important concern in biodiversity conservation. Callithrix aurita is endemic in regions of high-altitude forests of the Atlantic forest of southeastern Brazil. The most relevant criteria of fitting as endangered species are: habitat destruction, inability to adapt to degraded secondary forests, population decline, restricted distribution and introduction of invasive alien species. These criteria, coupled with the apparent rarity, explain its inclusion on the Official List of Species of Brazilian Fauna Threatened with Extinction. The objectives are: to estimate the population size of C. aurita, C. penicillata and their hybrids in the Serra dos Órgãos National Park, assess hybridization between species by morphology and laboratory check the health status and confirm the involvement of C. aurita in the fatherhood of trapped animals, propose a plan for eradication and control of invasion of C. penicillata in the Park. The population sizes of the two primate species were estimated by the method "Distance Sampling". A total of seven marmosets were captured with live traps set for the chemical and physical restraint and subsequent completion of the procedures. For the haemogram, the biochemical and genetic analysis, blood was collected in a test tube containing anticoagulant and kept at refrigerator temperature until the moment of handling / processing of samples. Callithrix aurita appears to be well preserved only in the park area corresponding to the portion located in the city of Petrópolis. The cytogenetic and molecular analysis of hybrids are a useful tool to confirm whether or not hybridization, identifying the species involved and seeing if there is a tendency in the backcrosses. One may suggest that there is a tendency for species differentiation and identification of hybrid individuals by standard hematological and biochemical, to be confirmed with a larger sample of the species C. aurita, preferably from the same locality and under the same conditions. In the case of C. aurita, the main recommendations for its conservation research to include the registration of other populations in areas of distribution free of intrusion, so you can evaluate the chances of population recovery and species survival. The creation of new protected areas should be encouraged, as well as more detailed studies on the species already known sites of occurrence, and a safe program of captive breeding.

Full textHistoriska byggnader, byggnader uppförda före 1945, utgör en tredjedel av det totala byggnadsbeståndet i Sverige. Historiska byggnader har ofta kulturhistoriska värden som måste beaktas vid energieffektiviseringar. Detta examensarbete syftar till att undersöka påverkan på primärenergianvändning och CO2-utsläpp genom optimering av livscykelkostnaderna (LCC) för historiska byggnader. Som fallstudie används 920 historiska byggnader i Visbys innerstad, indelade i tolv olika typbyggnader (6 träbyggnader, 1w-6w, och 6 stenbyggnader, 1s-6s). Tre fall undersöks: referensfall utan implementerade energieffektiviseringsåtgärder (fall 1), lägsta möjliga LCC (fall 2) och en minskning av energianvändningen med 50 % (fall 3). Inom examensarbetets kommer även de mest lönsamma energieffektiviseringsåtgärderna tas fram. Examensarbetet kommer också att visa hur lönsamheten för energirenovering varierar mellan de olika typbyggnaderna. Vid utförandet av examensarbetet tillämpas en tvärvetenskaplig metod som beaktar både kulturhistoriska värden och energibesparing. Tyngdpunkten ligger dock på användningen av programmet Optimal Energy Retrofit Advisory-Mixed Integer Linear Programming (OPERA-MILP), som är en del av den tvärvetenskapliga metoden. Med användningen av OPERA-MILP erhålls den kostnadsoptimala energieffektiviseringsstrategin för en byggnad. Programmet beaktar alla energirelaterade investeringskostnader, samt investering- och driftkostnader för värmetillförselsystem, under en bestämd tidsperiod. Resultaten visar unika energieffektiviseringspaket för de olika typbyggnaderna med en potential att sänka totala LCC för byggnadsbeståndet med 4-11 % och samtidigt minska energianvändningen med mer än 50 %. Examensarbetet visar också en möjlig minskning i primärenergianvändning med 24-57 %. CO2-utsläppen varierar mycket beroende på vilka antaganden görs relaterat till elektricitetsproduktion och användning av biomassa; resultaten visar ökningar upp till 224 % i CO2-utsläpp men också minskningar ned till 85 %. Samtliga typbyggnader är ekonomiskt lönsamma att energirenovera med LCC-besparingar på 1,4-11,8 SEK med en livscykel satt till 50 år för varje årligen sparad kWh, förutom i fall 3 då kostnader uppstår för varje årligen sparad kWh med 10,0-17,2 SEK, för ett antal av typbyggnaderna.

The ecological knowledge, derived from human handling natural resources, is related to each individual perception of the environment where one lives. This study had as main goals, evaluate the ecological knowledge and the environmental perception of a rural community towards primates, located in the surroundings of the Private Reserve of Natural Heritage (RPPN) “Engenho Gargaú”, in the state of Paraíba, where Alouatta belzebul (redhanded howler monkey), Sapajus flavius (blond capuchin monkey) and Callithrix jacchus (common marmoset) species live.

This study had as main goals, evaluate the ecological knowledge and the environmental perception of a rural community towards primates, located in the surroundings of the Private Reserve of Natural Heritage (RPPN) “Engenho Gargaú”, in the state of Paraíba, where Alouatta belzebul (redhanded howler monkey), Sapajus flavius (blond capuchin monkey) and Callithrix jacchus (common marmoset) species live. Two hundred semi-structured interviews with adults were performed and one hundred and two children’s mental maps were collected. The answers from the interviews were evaluated by the Thematic Content Analysis and they received specific scores to formulate a wise Local Ecological Knowledge measure (CELP). In spite of the proximity with RPPN “Engenho Gargaú” the interviewed adults had a poor ecological knowledge. However, the ones who had a more significant contact with primates, the man and residents who lived longer in the community showed a significantly higher CELP compared to the other residents. The age group did not influence the CELP results. Apparently, the community does not overly explore RPPN resources, justifying the poor ecological knowledge among residents. According to the mental maps, the children who had already seen primates showed a more realistic and detailed environmental perception than the ones who had never seen primates, showing a bigger contact with the environment and, possibly, with the RPPN. These data are able to help future researches and Environmental Education actions, specifically involving A. belzebul and S. flavius from RPPN “Engenho Gargaú”, two of the five target species included in the Brazilian government conservation action planning system “Plano de Ação Nacional para Conservação dos Primatas do Nordeste” (PAN PriNE). performed and one hundred and two children’s mental maps were collected.

O conhecimento ecológico, proveniente do contato humano com os recursos naturais, está relacionado com a percepção que cada indivíduo tem do ambiente em que vive. O presente estudo teve por objetivos avaliar o conhecimento ecológico e a percepção ambiental sobre primatas por uma comunidade rural no entorno da Reserva Particular do Patrimônio Natural (RPPN) Engenho Gargaú, na Paraíba, onde habitam as espécies Alouatta belzebul (guariba-de-mãos-ruivas), Sapajus flavius (macaco-prego-galego) e Callithrix jacchus (saguido-nordeste). Foram realizadas 200 entrevistas semiestruturadas com adultos e coletados 102 mapas mentais de crianças. As respostas das entrevistas foram avaliadas pela Análise de Conteúdo Temático que receberam pesos específicos para formulação de uma medida ponderada do Conhecimento Ecológico Local (CELP). Apesar da proximidade com a RPPN Engenho Gargaú, os adultos apresentaram um baixo conhecimento ecológico. No entanto, os que possuem um maior contato com os primatas, os homens e os moradores mais antigos apresentaram um CELP significativamente mais elevado comparado aos demais. A faixa etária não influenciou no CELP. A comunidade aparentemente não explora intensamente recursos da RPPN, justificando o baixo conhecimento encontrado no local. De acordo com os mapas mentais, as crianças que já avistaram primatas mostraram uma percepção ambiental mais realista e detalhada do que aquelas que nunca avistaram, evidenciando um maior contato com o meio ambiente e, possivelmente, com a RPPN. Tais dados podem subsidiar futuras pesquisas e ações de Educação Ambiental, especificamente envolvendo A. belzebul e S. flavius da RPPN Engenho Gargaú, duas das cinco espécies alvo do Plano de Ação Nacional para Conservação dos Primatas do Nordeste (PAN PriNE).

Full textThe orangutans (Pongo pygmaeus and Pongo abelii), living on the islands of Borneo and Sumatra are amongst the first victims of the large-scale deforestation and exploitation of the south-east tropical rainforest and their future is today joepardized. The increasing orangutan pet trade is accelerating even more this decline. The situation is so critical that if nothing’s done, the researcher hypothesized that orangutan will be extinct in the next ten years (van Schaik et al 2001). Several intitiatives and measures have been set up (???) to stop the pet trade on one hand and protect the last remaining wild population and their habitat on the other hand. Rehabilitation and reintroduction of confiscated orangutans back to their original habitat was initiated in the 1960s in the double perspective of fighting against the orangutan pet trade and reinforce the already established wild populations. This method implies for the Primates a complete cognitive restructuration as well as a re-shaping of their behaviours in accordance with their awaiting new way of life. They have to lose the dependance towards humans that has been imprinted on them during their captivity, avoid contact with humans and acquire the behavioural repertoire of the species. The orangutan community that has been reintroduced in the Meratus forest since 1997 presents an ideal opportunity to study the success and failures of the readaptation of individual whose maternal bond has been broken at various ages, interrupting their learning phase and try to understand which abilities were deficient or absent in those individuals. This study enable us also to evaluate the relevance of reintroduction in the conservation efforts of great Apes
