Abstract:
Invasive Acacia species can alter nutrient cycling processes in forest ecosystems, particularly affecting total litterfall production and litter decomposition patterns. This study examined the effects of exotic Acacia mangium Willd. on total litterfall production, nutrient concentrations in leaf litterfall fractions, leaf litter decomposition, and nutrient release in lowland heath (HF) and mixed dipterocarp forests (MDF) in Brunei Darussalam, Borneo. Above-ground litterfall traps were installed in HF and MDF with and without invasive Acacia present, representing four habitat types in total, and monthly collections were conducted for 12 months. Litter decomposition bags were deployed to determine the rates of decomposition and nutrient release. Habitats invaded by Acacia exhibited higher total litterfall production, increased leaf litter concentrations of nitrogen, potassium, and calcium, and increased addition of all nutrients measured in litter (nitrogen, phosphorus, potassium, calcium, and magnesium, especially in the Acacia-invaded mixed dipterocarp forest (AMDF) and nitrogen and potassium in Acacia-invaded heath forest (AHF)), reduced nitrogen and potassium use efficiencies in AHF, and reduced stand-level nitrogen and calcium use efficiencies in AMDF. Litter decomposition rates and nutrient release were lower in AMDF than in the three other habitats. The significantly higher total litterfall production coupled with higher nutrient addition in the two Acacia-invaded habitats is expected to progressively increase the abilities of these habitats to produce large quantities of nutrient-rich litter and will likely eventually lead to an enrichment of nutrients in the soil, thus facilitating further invasion by Acacia, particularly in the MDF.

Abstract:
AbstractStand structure and tree species diversity patterns were examined plot-wide and among four topographically defined habitats (plateau, cliff, low plain and depressions) in a 120-ha permanent plot in an Acacia-dominated savanna in Mpala Ranch, central Kenya. The four habitats were defined by clustering the 3000 quadrats of 20 × 20 m in the plot based on their altitude, slope and convexity. Structural and floristic differences among the four habitats were examined and species-habitat associations were tested for the 30 most abundant species using torus translation randomization tests. The plot included 113 337 trees in 62 species with diameter at knee height ≥ 2 cm (18.4 species ha−1), 41 genera and 23 families. Fabaceae with the genus Acacia were the dominant family, followed by Euphorbiaceae and Ebenaceae. Tree density and basal area were twice as high on low plain and depressions than on the plateau. Species richness was highest in the cliff and was seven times higher than in the adjacent plateau. Half of the species assessed showed significant positive associations with one habitat and 21 showed significant negative associations with at least one habitat. The variation in stand structure and tree species diversity within the Mpala plot shows that topography is among the important drivers of local species distribution and hence the maintenance of tree diversity in savannas.

Abstract:
Long-tailed macaque (Macaca fascicularis) is a quite adaptive animal so it could be found in a diverse range of habitat types, one of the habitats is Plantation Forest on peatlands. This study aims to obtain the information about the activity of long-tailed macaque related to habitat utilization at Plantation The operational activities in the Plantation Forest can affect the activities of long-tailed macaque, changing of food sources, and they have a potential to attack the Acacia plants, so it’s necessary to do research about the activity of long-tailed macaque related to the habitat utilization at Plantation Forest and to acknowledge the types of plants used by long-tailed macaque for food and shelter. This research is a descriptive study and the data are obtained through a focal animal sampling method in April and May 2019 at the Plantation Forest in Sungai Penyabungan District, Ogan Komering Ilir Regency. The focal animal sampling method used at 7.00-17.00 WIB with using interval of 10 minutes. Based on the study, the long-tailed macaque used the active time to feed (24.60%), rest (25.58%), move (27.92%), and social activities (21.89%) included vocalization, agonistic, and grooming. The vegetation parts consumed by the long-tailed macaque are leaves (42.30%), fruits (34.62%), and flowers (23.08%). The vegetation used as food is Acacia crassicarpa, Melaleuca cajuputi, and Melastoma malabathricum. The plant that’s most often used as food and shelter is Acacia crassicarpa.

Abstract:
I studied the selection of breeding habitat and nest microhabitat in Scarlet Robins Petroica multicolor and Eastern Yellow Robins Eopsaltria australis, in remnant woodland on the New England Tablelands of New South Wales in 2000?2002. Yellow Robins used breeding territories (n = 10) with significantly higher densities of rough-barked saplings, acacias and other (non-Acacia) shrubs than Scarlet Robin breeding territories (n = 10) and plots lacking Yellow Robins (n = 7). Yellow Robins nested mostly in gully and lower-slope positions, with a southerly aspect, >40 m from the woodland edge, whereas Scarlet Robins nested mostly on upper slopes and ridges, with no preferred minimum distance from the woodland edge. Most Yellow Robin nests (86% of 58) had overhead foliage within 1 m, shielding them from above, whereas over half (58% of 54) of Scarlet Robin nests were in unconcealed positions. Yellow Robin nests had significantly greater density of cover, and the surrounding habitat was more complex, than for Scarlet Robin nests, in 0.13-ha plots centred on the nest. Breeding success and fledgling survival in the Yellow Robin were positively related to the density of acacias, non-Acacia shrubs and rough-barked saplings (but not gum saplings) in breeding territories. Fledging success and juvenile survival in the Yellow Robin were also positively related to habitat complexity around nest-sites (but not distance to nearest cover, or items of cover within 20 m). Scarlet Robins had exposed nests and suffered high nest predation, with too few successful nests for comparison with unsuccessful nests. Habitat conservation for the Yellow Robin should address the complexity of the ground, shrub and sapling layer in woodland remnants; that for the Scarlet Robin may need to address foraging substrate and ecologically based control of nest predators.

Abstract:
The Mediterranean coastal dune habitat of Israel is diminishing rapidly, mostly due to massive urbanization, changes in habitat characteristics caused by dune stabilization and the presence of Acacia saligna, an invasive species brought to Israel for the purpose of dune stabilization. In this study we document the effect of sand stabilization on the composition of small mammal communities in the Ashdod-Nizzanim sands, Israel. We analyzed differences in species diversity and abundance for species of rodents in four types of habitat: unstable (mobile) sand dune, semi-stabilized dune, inter-dune depression and a plot of the invasive Acacia saligna. Rodent communities were found to undergo gradual changes concurrently with the stabilization of the sands. The mobile dune was the only habitat in which the strict psammophiles Jaculus jaculus and Gerbillus pyramidum were captured in abundance. No species commensal with human were captured neither in the mobile nor in the semi-stabilized dunes. However, in the inter-dune depression there was quite a large representation of Mus musculus, a rodent commensal with humans. The Acacia saligna plot had the lowest number of captures and the lowest rodent biomass calculated, with Mus musculus composing nearly half of the captures. The results of this study demonstrate that stabilization of the sands in Ashdod-Nizzanim area is associated with the disappearance of psammophile rodents and the appearance of species commensal with humans. In order to preserve the habitat for psammophile rodents, measures should be taken to halt the spread of acacia and the continuing stabilization of the sands.

Full text
Abstract:
Habitat fragmentation alters fire regimes by changing the spatial and temporal context in which fire operates, potentially altering ecosystem state and threatening taxa. In the fragmented wheatbelt of Western Australia, spatial patterns of contemporary fire and their effects on biodiversity conservation are poorly understood. We addressed this by: (1) determining if fire regimes differed between vegetation remnants of differing sizes and uncleared vegetation, using analysis of satellite imagery; (2) determining vegetation structural responses to time since fire in three habitats: mallee-shrub, Acacia shrublands and mallee-heath; and (3) exploring the consequences of these differences, using the fire-sensitive malleefowl (Leipoa ocellata) as a case study. Fire was infrequent in small remnants, more frequent in large remnants, and most frequent in uncleared areas. Key vegetation structural attributes for malleefowl, such as canopy and litter cover, increased beyond 45 years post-fire in mallee-shrub, reached a plateau in mallee-heath after 30–40 years, and declined in Acacia shrublands after 25–40 years. Senescence in long-unburnt vegetation, combined with rare contemporary fires, suggest progressive decline in habitat quality of Acacia shrublands for malleefowl in the wheatbelt. In the adjacent, continuously vegetated landscapes, more frequent (and extensive) fires in structurally developing mallee-shrub communities are of concern for malleefowl conservation.

Abstract:
This study was carried out to determine how disturbances could shape the natural occurrence of African meliponine bee species in different ecological habitats of Taita hills of Kenya and how this could lead to changes in their diversity. Habitats sampled were indigenous forests, exotic forests, mixed highland forests, Acacia dominated bush lands, mixed deciduous woodlands and grasslands which were further categorized as either fragmented or un-fragmented habitats based on levels of disturbance. The study sites were chosen based on various features such as, forest fragment size, level of forest fragment isolation, forest fragment age, and level of degradation. In all study locations, meliponine bee species were sampled using the conventional complementary method, belt transect (direct observation of nesting colonies synonymous to a visual census) from the months of March to September 2014 (combining both the long rainy season and dry season). Nesting colonies of the 4 meliponine bee species, namely, Hypotrigona gribodoi, Meliponula ferruginea (black), Hypotrigona ruspolii and Plebeina hildebrandti, were surveyed following a successive gradient. In each study site (25 ha), 20 linear transects of 250 m × 20 m each were established using a global positioning system (GPS) receiver to mark coordinates with relation to habitat type. Data such as nesting site/substrate, GPS coordinates of nest, and names of nesting trees were recorded. A total of four species depicted by the Renyi diversity profile was recorded in five out of the six main habitat types surveyed and a further extrapolation with Shannon index (EH) also predicted the highest species richness of 4.24 in a deciduous habitat type with more trees and vegetation and the lowest species of 1.01 in isolated forest patches habitat type. These meliponine bee species (Hypotrigona gribodoi, Hypotrigona ruspolii, Meliponula ferruginea (black) and Plebeina hildebrandti) were observed to be unevenly distributed across all six sampled habitats, further indicating that mixed deciduous habitat proved to be more diverse than Acacia dominated bush lands, grasslands and exotic forest strips which have all undergone varying levels of fragmentation. This has revealed that unprecedented conversions of natural habitats leading to fragmentations of such habitats is a key driving factor causing increased habitat isolation and vulnerability in this afro-montane region which may potentially distort local assemblages of native pollinators such as meliponine bee species.

Abstract:
The Grizzled Giant Squirrel (GGS) Ratufa macroura (Pennant, 1769) is a ‘Near Threatened’ and endemic giant squirrel distributed in southern India and Sri Lanka. In India, the species is distributed in more than 10 locations between Cauvery Wildlife Sanctuary in Karnataka in the north and Srivilliputhur Grizzled Squirrel Wildlife Sanctuary in Tamil Nadu in the south. A study was conducted in the riparian habitats of Chinnar Wildlife Sanctuary in Kerala to understand the habitat characteristics, including the drey site use of GGS. The vegetation of the GGS habitat was studied using the quadrat method, and the dreys were counted using the transects. A total of 95 species of trees were identified from the riverine vegetation, and the GGS used 36 species of trees for drey construction. Most of the dreys were found on Mangifera indica, Terminalia arjuna, Ficus microcarpa, Diospyros ebenum, and Pongamia pinnata. However, the GGS may prefer trees such as Mitragyna parviflora, Diospyros ebenum, Ficus microcarpa, Albizia procera, Acacia nilotica, and Acacia leucophloea for drey construction. The study also highlights the usage of large trees with extensive crown by the GGS for various activities such as feeding, resting, moving, and nesting, thus signifying the necessity for protecting the remaining riverine habitat at Chinnar Wildlife Sanctuary to ensure the long-term conservation of GGS. We recommend an urgent restoration by restocking with already existing, native tree species of the riverine habitat due to the extremely poor regeneration of trees in the riverine habitat that support the only population of the GGS in Kerala.

Abstract:
Thesis (MScConsEcol (Conservation Ecology and Entomology))--Stellenbosch University, 2008.
The fynbos eco-region in the Western Cape lowlands has been extensively transformed by anthropogenic activities such as agriculture and urban development, as well as invasive alien plants. Elandsberg Private Nature Reserve and Farms lies on Swartland Alluvium Fynbos and has been largely fragmented by agricultural crop production, whilst Riverlands Nature Reserve together with the Pella Research Site, which lie on Atlantis Sand Fynbos, are under severe threat from the invasive woody alien Port Jackson Willow (Acacia saligna) which forms dense stands in the lands adjacent the nature reserve. Habitat transformation has resulted in subsequent loss of habitat and a reduction in habitat value for small mammal communities by creating a mosaic of optimal and sub-optimal habitats. The success of A. saligna is, in part, attributed to its production of copious amounts of small hard-shelled seeds and well established soil seed banks. In the first part of this study we investigated the effect of habitat transformation on resident small mammal communities by comparing small mammal species richness, diversity and abundance between natural and transformed habitats as well as between the two vegetation types. We also investigated the population demographics of the striped mouse (Rhabdomys pumilio) in the different habitats. Our study shows that whilst fragments of natural habitats, especially at Riverlands and Pella, may be playing an important role in harbouring rare and possibly endangered species, transformed habitats are also important as secondary habitats providing both cover as well as seasonal food resources. Reproduction and body condition in R. pumilio were dependent on seasonal changes such as availability of water and food resources in the habitats. The second part of this study was carried out to investigate the effect of alien plant invasion on the resident small mammal communities at Riverlands Nature Reserve and to determine the role of small mammals in the removal and predation of A. saligna seeds. Rodent species richness, diversity and abundance were very low in the A. saligna stands compared to the adjacent fynbos vegetation. The interaction of rodents with seeds (removal or predation) was dependent upon seed size and seed abundance in the habitats. Whilst rodents may play an important role in predator limitation in the acacias, it is also possible that they may be playing a significant role in dispersing the seeds of acacias into the fynbos. More work is required to fully understand the role small mammals play in seed predation, dispersal and limitation in alien invaded fynbos systems.

For a long time the markets were seen as an abstract entity, regulated by offer and demand for products, and disconsidered the importance of social interaction in their formation. Therefore, this study aimed to comprehend the factors that contributed to and conditioned the shape of the market structure of Acacia mearnsii De Wild in Rio Grande do Sul, as well as understand the different roles of agents and institutions in the social construction of this market. This work specifically intended: identify agents that compose the market for Acacia mearnsii and their roles; map the network of relationships of the agents in the market; understand the effect of social, technical, economic and political aspects in the development of market of Acacia mearnsii in Rio Grande do Sul. For this was selected the New Economic Sociology (NES) as the theoretical basis. Pierre Bordieu was the main visited author, due of his theory of fields and capital, and for understand that the action of agents is conditioned by the existent structure and the structure is conditioned by the habitus of agents. Other authors such as Fligstein, Swedberg, Steiner and Abramovay also have meaningful participation in the study due to their contributions to the area. The methodology used to conduct this study was the case study, and the market of Acacia mearnsii was considered the case to be analyzed. To obtain the data, semi-structured interviews were realized in ten cities of RS, with the main companies of the sector, along forest producers that operate in different ways and with different strategies, and with the company Technical Assistance and Rural Extension (TARE). As a secondary source, we used data of IBGE, Emater / Ascar and various agencies connected with the section. Thus, it was concluded that the market of Acacia mearnsii is a social construct composed of several agents, identified eleven kinds, each with distinct characteristics and strategies. It was noticed that this market had its beginning promoted by the exploration of the shell for the production of tannin. In a second moment, comes the production of charcoal, the main way to use the wood until the 1990s, and from 1995 began the exploration of wood for the purpose of producing splinter for export, considerably modifying the field. It was also noticed that this market was conditioned by several factors such as the concentration of capital from major companies; the influence of formal and informal institutional environment on the action of the agents, materialized by environmental and labor laws and culture; the lack of labor, indifferently of the size of the producer; the problem of the succession of family foresters; the lack of cooperation between small producers to market their products; the ability of social enterprises and their influence on other agents; habitus colonist forester and coal producer, among others.
Por muito tempo os mercados foram entendidos como uma entidade abstrata, regulada pela oferta e pela demanda dos produtos, e que desconsiderava a importância da interação social na sua formação. Assim, este trabalho teve como objetivo geral compreender os fatores que concorreram e que condicionaram o formato da estrutura do mercado da acácianegra (Acacia mearnsii De Wild) no Rio Grande do Sul, bem como entender os distintos papéis dos agentes e das instituições na construção social deste mercado. Especificamente pretendeu-se: identificar os agentes que compõem o mercado de acácia-negra e seus papéis; mapear a rede de relações dos agentes existente no mercado; compreender o efeito dos aspectos sociais, técnicos, econômicos e políticos no desenvolvimento do mercado da acácia-negra no Rio Grande do Sul (RS). Para isto selecionou-se a Nova Sociologia Econômica (NSE) como o arcabouço teórico de base. O principal autor visitado foi Pierre Bourdieu, em virtude da sua teoria dos campos e dos capitais, e por entender que a ação dos agentes é condicionada pela estrutura existente e a estrutura é condicionada pelo habitus dos agentes. Outros autores como Fligstein, Swedberg, Steiner e Abramovay também tiverem participação destacada no estudo devido às suas contribuições para a área. A metodologia utilizada para a realização deste trabalho foi o estudo de caso, sendo que o mercado da acácia-negra foi considerado o caso a ser analisado. Para a obtenção dos dados, foram realizadas entrevistas semiestruturadas, em dez municípios do estado do RS, junto às principais empresas do setor, junto a produtores florestais que atuam de distintas formas e com estratégias diferentes, e juntamente à empresa de Assistência Técnica e Extensão Rural (ATER). Como fonte secundária, foram utilizados dados do IBGE, da Emater/Ascar e de diversos órgãos ligados ao setor. Desta forma, concluiu-se que o mercado da acácia-negra constitui uma construção social composta por diversos agentes, sendo identificados onze tipos, cada um com características e estratégias distintas. Percebeu-se que este mercado teve seu início impulsionado pela exploração da casca destinada à produção de tanino. Em um segundo momento, surge a produção de carvão vegetal, principal forma de utilizar a madeira até os anos 1990 e, a partir de 1995, iniciou-se a exploração da madeira com a finalidade de produzir cavaco para exportação, modificando consideravelmente o campo. Também notou-se que este mercado foi condicionado por vários fatores, como a concentração dos principais capitais junto às empresas; a influência do ambiente institucional formal e informal sobre a ação dos agentes, materializado pelas legislações ambientais e trabalhistas e pela cultura; a falta de mão de obra, indiferentemente do porte do produtor; o problema da sucessão dos silvicultores familiares; a falta de cooperação entre os pequenos produtores para a comercialização de seus produtos; a habilidade social das empresas e a sua influência sobre os demais agentes; o habitus do colono silvicultor e produtor de carvão, entre outros.

The economic development in Brazil is strictly related to the solution of its social problems, among which the housing deficit that has been fought by the implementation of the federal Program Minha Casa Minha Vida (PMCMV). Since 2009, the program has settled 20,000 families in housing units in the range of 0 to 10 minimum wages, in the categories of resettlement and lottery. This work seeks to investigate the process of deterritorialization of dwellers, made effective by the City of Rio de Janeiro, from Favela de Acari, a squatter community, to a new housing complex financed by PMCMV and built in the neighborhood of Cosmos, after the torrential rains of 2009 that dislodged the population from the margins of Acari River. The main objective is to investigate the resettlement process, since the removal of the families from risk areas, independently from its will or choice. The resettlement occurs within a rational of real state expansion by the Federal Bank Caixa, main operator of the Program that finances developers and builders that select under valued land in order to reduce the budget and maximize profit. From the empirical experience in the social groups? deterritorialization and reterritorialization process from Acari to Cosmos, and the use of those concepts, as well as appropriation and belongingness, this research will reflect on the housing policies conduction, not only as a means of the national housing deficit reduction, but also on the building of the conditions for effective and comprehensive appropriation and sense of belonging of dwellers in their new places, focusing on the people?s needs and improvement of their quality of live.

 The Bridled Nailtail Wallaby, Onychogalea fraenata, was once widespread throughout eastern and south-eastern Australia, but is now found primarily at Taunton National Park (Scientific). With a population reduced to fewer than 500 individuals, survival of the species is dependent on the sustainability of suitable habitat in the present, and its continued availability in the long-term. 

While dietary selection and habitat utilisation have been investigated, the interrelationships between nailtail habitat components have not been examined. This study was conducted to address that issue. The aim was to develop a method of predicting nailtail populations in diverse habitats, with the ultimate goal being the identification of habitat conducive to continued nailtail survival. 

Data were gathered from six sites on Taunton National Park. Two sites corresponded to each of the following categories: low, medium and high nailtail population levels. These sites were examined to determine trends or patterns resulting in significant correlations between nailtail density and the floristic and shelter components. Components were found to fall within two basic habitat types: one favourable and the other unfavourable to the nailtail. 

In the favourable "Acacia habitat," interrelated floristic components consisted of Acacia trees and shrubs, Capparis, Opuntia, Schlerolaena and Parsonsia herbs, Capparis, Schlerolaena and Carissa shrubs, and Cenchrus, Cyperus, Paspalidium  and Sporobolus grass. Shelter components were comprised of Solid Logs, combined Solid Log -Hollow Log, combined Solid Log -Hollow Log -Woodpile, Shrub and combined Brigalow Regrowth -Shrub. 

In the unfavourable "gum -tree habitat", floristic components consisted of Eucalyptus, Cotymbia and Grevillea trees, Alphitonia, Eucalyptus, Grewia, Sida and Phyllanthus shrubs, Euphorbia, Cheilanthes and Hybanthus herbs, and Aristida, Eragrostis and Eriachne grass. Shelter components consisted of Trees, and variations of tree shelters to include Fallen Tree Crown, combined Tree -Live Tree Crown, combined Tree -Live Tree Root, and combined Tree -Live Tree Crown -Live Tree Root. 

To validate these proposed habitats, three additional study sites were selected on the Pine Grove, Red Rock Park and Rockview cattle properties adjacent to Taunton National Park. Based on habitat composition at these sites, the Pine Grove site was determined to be a low -to -medium nailtail density site; Red Rock Park a low -to - medium nailtail density site with the potential to support a high density of nailtails; and Rockview a medium nailtail density site. 

Based on the results of this study it is recommended that management of existing nailtail habitat incorporate the balanced mix of habitat components noted in the "Acacia habitat" while controlling the spread of "gum -tree habitat" components. Emphasis on floristic and shelter interrelationships is also considered essential in the establishment of future nailtail populations.

Abstract:
Dissertação de Mestrado Integrado em Arquitetura apresentada à Faculdade de Ciências e Tecnologia
Situado na costa atlântica, no interior do Pinhal de Leiria, encontra-se um lugar de excelência cultural e ambiental. Um local de tradição balnear e de recreio, que teve o seu auge na segunda metade do século XX, mas tem vindo a sofrer uma decadência nas últimas décadas. Esse lugar é São Pedro de Moel. Lugar perdido num contexto de relevância ibérica organizada através do desenho urbano de Lima Franco onde as habitações surgem por entre os pinheiros, num contínuo de baixa densidade criando uma linguagem e harmonia que não existe noutras estâncias balneares. Um território com inúmeras qualidades, onde residem 389 pessoas, que vivem em amizade com o pinhal, praia, dunas, arribas, fauna e flora. Estas unem-se a uma cultura forte e arquitetura de grande valor, criando paisagens de encanto e beleza. Devido à sua localização geográfica privilegiada, ao longo do tempo desenvolveu-se um interesse neste local como um destino balnear e de veraneio, o que levou a que construíssem aqui as suas segundas habitações. Assim tornou-se um destino que não vivia para além da busca pela praia, estando despovoado durante a maioria do ano. Para além disto, devido às questões climatéricas, a praia tem vindo a desaparecer, sendo necessário criar novas dinâmicas e atrativos que tirem proveito das qualidades únicas desta povoação, e torná-la num destino como nenhum outro da costa portuguesa, um destino singular. Assim, a presente dissertação tem como objetivo repensar a organização espacial deste território, em articulação com um programa de valorização que possa estabelecer um destino balnear renovado, com propostas para combater a sazonalidade extrema, que afeta o desenvolvimento e a qualidade de vida dos cidadãos. Deste modo, este estudo tem a intenção de reformar a entrada norte de São Pedro de Moel, mais precisamente a costa marítima, “onde a terra se acaba e o mar começa”. Uma costa alta e rochosa numa extensão de quase 2km de arribas. Um local cheio de potencial, com paisagens e valores naturais de excelência, a pedir para ser habitado. Unir-se-á aos caminhos existentes pelo Pinhal, garatindo o percurso circular do território, e permitir a visita a todos os espaços de valor. Também a construção de um edifício com um programa de lazer e recreio que possa ser usado por todo o tipo de público, horário e estação do ano, possibilitará a atração de pessoas de todas as faixas etárias para São Pedro de Moel. Será um espaço tão emblemático como as velhas piscinas oceânicas, sem afetar a pacatez tão apreciada pelos residentes. Pretende-se, através da proposta individual, reestruturar, consolidar e dinamizar o território, através da vivificação das arribas.
Located in the Atlantic coast, inside the pine forest of Leiria, there is a place of cultural and environmental excellence. A place of recreation and beaches, which reached its peak in the second half of the 20th century, suffering a decline over the past few decades. That place is São Pedro de Moel. An urban place lost in a context of Iberian relevance organized through the urban design of Lima Franco, where the houses appear in between the pine forests, in a low-density continuum, creating a language and harmony that cannot be found in any other seaside area. A territory with countless qualities, where 389 people reside amicably with the forest, beach, dunes, cliffs, fauna and flora. These are all bonded to a strong culture and architecture of great value, creating landscapes of charm and beauty. Due to its privileged geographic location, people developed an interest in this location as summer vacation destination over time, which led to them building their second homes here. Therefore, it became a destination that did not live beyond its beach appeal, being unpopulated during most of the year. Furthermore, due to climate issues, the beach has begun to disappear, so it is necessary to create new dynamics and attractions that take advantage of the unique qualities of this village, and to turn it into a destination like no other in the Portuguese coast, a unique one. All in all, this dissertation has the purpose of rethinking the spatial organization of this territory. So is done in articulation with a recovery program that can establish a renewed seaside destination, providing ideas to counter the extreme seasonality, which affects the development and life quality of the citizens. In sum, this study purposes to reform the north entrance of São Pedro de Moel, more precisely the seacoast, “where the land ends and the sea begins”. A high and rocky coast that extends for almost 2 km of cliffs. A place filled with potential, landscapes and natural values of excellence, asking to be inhabited. It will join the already existing paths throughout the forest, guaranteeing the circular route of the territory, and enable visits to all the spaces of value. Also, the construction of a building with a leisure and recreation program that everyone can use at any time and during every season, will attract people of all age groups to São Pedro de Moel. It will be a space as emblematic as the old ocean pools, without interfering with the peacefulness that the residents appreciate so much. In short, the present proposal aims to restructure, consolidate and revitalize the territory, through the vivification of the cliffs.

Abstract:
A questão que se abre neste trabalho refere-se à necessidade de encontrar novas formas de produzir conhecimento nas Ciências Sociais Aplicadas, mais especificamente no campo do Planejamento Urbano e Regional. Verifica-se uma certa rigidez na escrita acadêmica que acaba por limitar o acesso das discussões ao próprio campo de estudo e seus complementares. O espaço das cidades é o principal tema das pesquisas da área, mas quem constrói as cidades? Quem habita e vive nas cidades? O que estudamos é justamente os caminhos e descaminhos que a sociedade como um todo elabora, porém não participa das reflexões e discussões, tão pouco tem conhecimento da potência da própria experiência como meio de transformação e ação social.

Abstract:
Introdução: A modificação de rios por conta da atividade antropogênica ameaça os ecossistemas de água doce do mundo. A intensificação dessas modificações facilita a entrada de outras espécies, contribuindo para uma crise na biodiversidade aquática, ou seja, implicando em um desequilíbrio ecológico. Visto que, com a bioinvasão de espécies não nativas em diversos ecossistemas, acaba agravando em perdas, de espécies locais, por conta da concorrência de alimento e habitat. Dentro das Bacias hidrográficas da América do Sul a do Rio Paraná é a segunda maior, apresentando uma alta diversidade ictiofaunísticas abrigando mais de 250 espécies de peixes, no entanto, ao longo dos anos vem sofrendo com o avanço das atividades antropogênicas. Objetivo: devido a isto, esta revisão teve como objetivo compilar informações disponíveis na literatura científica a respeito das principais espécies de peixes invasoras da Bacia do Rio Paraná. Materiais e Métodos: Buscas de dados em artigos científicos nas principais bases: Scopus, Science Direct, Google Acadêmico, Periódicos Capes e que referenciou-se as principais espécies de peixes invasoras na Bacia do rio Paraná. Resultados e Discussão: Muitas vezes os peixes são introduzidos de forma informal, como incidências de escapes das produções aquícolas, de aquarismo ou utilização para isca viva para a promoção da pesca esportiva, entretanto, necessita de estudos sobre suas características de vida e seu potencial impacto em seu novo habitat, pois estas espécies introduzidas podem gerar sérios problemas ecológicos no ecossistema em/ou a longo prazo. Conclusão: Concluindo-se que essas interferências geram impactos ecológicos, tais como a extinção e declínio de espécies nativas, que são decorrentes da competição exclusiva, da predação, da transmissão de patogenicidades e até mesmo da hibridização com outras espécies, necessitando o controle e até mesmo a erradicação destas espécies não nativas.

Abstract:
Introdução: Ações antrópicas vêm aumentando, principalmente no que diz respeito ao ambiente aquático, o que acaba prejudicando a vida de seres que dependem desse ambiente para sobreviver. O trabalho refere-se ao peixe-boi da Amazônia (Trichechus inunguis), um animal exclusivamente de água doce, o qual as explorações de biotas aquáticas interferem diretamente no seu ciclo de vida. Objetivo: avaliar o conhecimento da sociedade a respeito do T. inunguis, para que possa entender quais motivos levaram esse mamífero estar em vulnerabilidade, já que existe um acervo de estudos a respeito de sua conservação. Materiais e Métodos: O material de análise foi uma pesquisa pública on-line disponível no Google formulário com a participação de voluntários. Resultados: 74,1% responderam que já viu um peixe-boi em Zoo/Parques públicos; 13,8% na Natureza; 6,7% em Centro de Pesquisa e 5,4% na Universidade. Referindo-se a conservação da espécie, os zoológicos se inserem como um importante meio de desenvolver táticas de manejo de espécies ameaçadas para esses espaços; 78,2% disseram que os peixes-boi não são frequentes na natureza, devido sua exploração comercial, 78,2% não causam mal, nas literaturas pesquisadas não foi encontrado qualquer tipo de maleficio que a espécie possa causar ao homem; 92% responderam são mamíferos, porque apresentam glândulas mamárias iguais das sereias das lendas; 96% responderam que habitat preferencial é o ambiente aquático, 59,2% se alimentam de leite/vegetação, quando filhote, eles se alimenta basicamente de leite materno durante os primeiros meses vida, 86,8% disseram que existe dimorfismo sexual, se dá pela abertura genital na região ventral na fêmea próximo ao ânus e no macho próximo a cicatriz umbilical. 85,6% responderam que essa reprodução é sexuada; quanto ao tempo de gestação, 49,4% responderam não saber. 94,3% o peixe-boi é importante para o meio ambiente, sua urina rica em fósforo e sais minerais ajuda na eutrofização maciça da água; quanto ameaças 83,3% disseram que caça, degradação do habitat, lixo, currais de pesca são ações que mais comprometem a sobrevivência da espécie. Conclusão: grande percentual de pessoas não conhece seu modo de reprodução. Logo não conseguem ou não interligam o assunto com a vulnerabilidade da população de peixe-boi.

Abstract:
Introdução: Os peixes de água doce neotropicais apresentam uma biodiversidade maior do que a de qualquer outro grupo de vertebrados do planeta, não obstante, o conhecimento a respeito da taxonomia, ecologia e evolução da ictiofauna neotropical permanece incipiente, com centenas de novas espécies sendo descritas anualmente. Estudar corpos d’água intermitentes configura um desafio, visto que são ambientes que desaparecem em determinados períodos do ano, o que acaba fazendo com que a literatura a respeito deste tipo de ambiente apequene-se em comparação aos perenes. Objetivo: Apresentar e caracterizar a ictiofauna de dois riachos intermitentes localizados em uma região de transição entre os biomas Cerrado e Pantanal, contribuindo para aprimorar o conhecimento a respeito das espécies neotropicais e a influência das mudanças no habitat com as populações ali presentes. Materiais e métodos: A ictiofauna de ambos os corpos d’água fora amostrada periodicamente durante o período chuvoso e de seca entre os meses de maio à novembro, o material foi coletado utilizando tarrafas, redes de arrasto e puçás, posteriormente a captura dos exemplares estes foram conservados e catalogados. Resultados: A diversidade de espécies variou negativamente com o avanço de período de estiagem entre os meses de Junho a Setembro. Foi coletado um total de 955 peixes de 52 espécies diferentes, incluindo registros novos para a ciência. As ordens Characiformes e Siluriformes foram as mais abundantes, constituindo 85% da diversidade total de espécies encontradas nos corpos d’água, adicionalmente, foi observada uma marcante homogeneização em ambos os ambientes, onde o gênero Serrapinnus constituiu respectivamente 86,9% de todos os exemplares coletados no Córrego Furna da Beira Alta e 56,5% no corpo d’água sem nome aos meses de outubro e novembro. Conclusão: Considera-se, portanto, a necessidade da rápida caracterização e implementação de planos de proteção para a ictiofauna e os ambientes aquáticos continentais, em especial os intermitentes.

Abstract:
Introdução: As tartarugas marinhas são animais de habitat oceânicos e costeiros que migram para áreas de desovas apenas na época de reprodução, no mundo existem sete espécies, sendo que cinco têm ocorrência no Brasil. Todos esses animais apresentam ciclo de vida longo e atingem a maturação sexual tardiamente. A determinação sexual é definida de acordo com a temperatura de incubação, fatores externos do ambiente também podem influenciar no desenvolvimento dos ovos. Objetivo: Apresentar a importância da temperatura na determinação do sexo de tartarugas marinhas. Materiais e Métodos: Foi realizada uma pesquisa na plataforma Google Scholar utilizando as palavras-chave em português: Sexo; Temperatura; Tartarugas Marinhas, um total de 10 artigos foram utilizados como base para esse resumo. Resultados: Para determinação sexual desses animais a temperatura da incubação dos ovos é o que vai definir o desenvolvimento de machos ou fêmeas. Há uma média de temperatura chamada pivotal que resulta em uma proporção de metade de filhotes fêmeas e metade machos, essa temperatura é variável de acordo com a espécie, assim temperaturas mais elevadas que a pivotal favorecem o nascimento de fêmeas (a temperatura favorece a atividade da enzima aromatase que é responsável por converter a testosterona em estradiol), enquanto temperaturas mais baixas favorecem o nascimento de machos. Essa diferenciação ocorre durante o terço médio de incubação em um período termossensível, sendo que a temperatura durante o 40º dia de incubação é a determinante para o sexo. Fatores como tamanho do ninho, sua composição e coloração interferem na temperatura dentro do ninho. Fatores externos como condições climáticas, temperatura ambiente, precipitação e vegetação no local podem influenciar no metabolismo dos ovos alterando o tempo de incubação. Em todos os artigos observados foi constatado uma predominância no nascimento de fêmeas. Conclusão: Devido às mudanças climáticas globais está tendo um maior número de nascimento de fêmeas em detrimento aos machos, o que acaba afetando as populações de tartarugas no mundo causando uma perda genética, o que pode acarretar com a extinção de algumas espécies. É preciso adotar estratégias conservacionistas nas áreas de nidificação a fim de proporcionar um maior equilíbrio para o nascimento de machos.

Abstract:
En la situación pandémica actual estamos observando un aumento de los casos de duelo y duelo complicado que consultan o solicitan tratamiento en nuestra práctica clínica. El consumo de tóxicos puede aparecer en distintas etapas del duelo y existe una relación positiva entre duelo complicado y abuso de sustancias, con pacientes con abuso de sustancias presentando mayor riesgo de desarrollar un duelo complicado. En este sentido es especialmente relevante tener presente la posible comorbilidad entre trastorno por uso de sustancias y duelo complicado en la clínica actual. Es por ello que nos planteamos revisar varios casos clínicos en los que se pudiera observar esta comorbilidad y analizarlos para poder generar cierta discusión a este respecto. Seleccionamos dos casos de una consulta ambulatoria de la zona de Vallecas en Madrid en los que se produce comorbilidad entre duelo complicado y trastorno por uso de sustancias. Analizamos y exponemos ambos casos ya que se producen diferentes resultados de dicha interacción. En el caso 1 observamos un paciente con trastorno por uso de sustancias previo que presenta posteriormente duelo complicado sin recaer en el consumo al mantener un adecuado seguimiento y tratamiento psiquiátrico y psicológico. En el caso 2 observamos un paciente con consumo perjudicial de sustancias que, a raíz de un duelo complicado, acaba desarrollando un trastorno por uso de sustancias. La interacción entre ambos trastornos es conocida y puede complicar la situación clínica de nuestros pacientes. En la situación social en la que nos encontramos es importante estar atentos a pacientes que presenten esta comorbilidad entre duelo complicado y trastorno por uso de sustancia en nuestra clínica habitual para detectar y actuar en ambas patologías y así evitar potenciales complicaciones.

Abstract:
Coombs (1978) exposava una crisi mundial important de l'educació que, diverses dècades després, es manté. El seu autor ho definia en funció de tres qüestions: canvi, adaptació i disparitat. Pel que fa a l'última, esmentava l'existència d'una desproporció entre els sistemes educatius i el seu medi ambient, basant-se en quatre qüestions coincidents amb les assenyalades anys abans per Richmond (1971): fort increment de les aspiracions populars en matèria educativa, aguda escassetat de recursos, inèrcia inherent als sistemes d'educaci´o i inèrcia de la mateixa societat. Actualment, també hi ha una important crisi climàtica a escala planetària que s'ha convertit en un dels reptes més grans per a la població mundial, cada vegada més urbana. Des dels pobles i ciutats, i per a l'adaptació als seus efectes, cal incorporar consideracions ambientals a les polítiques urbanes que es duguin a terme, per disminuir els futurs riscos i respondre als reptes plantejats. L'urbanisme, pel seu paper integrador des de diferents enfocaments –ambientals, socials i econòmics– sobre el territori i els seus habitants pot ser fonamental per assolir les metes fixades. Des de l'àmbit docent és important visibilitzar aquests problemes amb l'alumnat i, en la mesura que sigui possible, apropar-los a la societat a través de solucions integrades. Abans aquestes circumstàncies és important estrènyer vincles entre la societat i la Universitat, amb l'objectiu de fer front a aquesta crisi ambiental, explorant nous camins entre la docència, investigació i la participació de la ciutadania des de la caracterització dels problemes, anàlisi, fins a les posteriors propostes. Des d'aquests reptes l'assignatura té com a objectius plantejar projectes reals que puguin atenuar la crisi ambiental actual a través de la sostenibilitat i augmentar-ne la resiliència, millorant la qualitat de vida dels seus ciutadans, i dotant el municipi d'una nova visió, des de la participació ciutadana , de com pot ser el seu espai públic, posant en valor els aspectes relacionats amb el medi ambient, el canvi climàtic, el disseny bioclimàtic i la salut. Aquesta sinergia es realitza a través de la metodologia d'aprenentatge-servei (ApS) ja que reuneix els processos aprenentatge i de servei a la comunitat en una única proposta metodològica, amb la intenció de realitzar un autèntic servei a la comunitat, que permeti aprendre i col·laborar en un marc de reciprocitat. En aquests anys, en altres propostes similars recopilades a L'Observatori Europeu d'Aprenentatge-Servei en Educació Superior (EOSLHE) es comprova com l'aplicació d'aquesta metodologia desencadena processos sistemàtics d'adquisició de coneixements i competències per a l'exercici de la professió i el desenvolupament personal en els alumnes, alhora que ha suposat un espai per a la reflexió sobre els projectes i les intervencions participat per estudiants, professors, veïns i corporacions. L'establiment d'Acords de col·laboració entre Universitat i ajuntaments, estableix les bases de participació entre la institució educativa i la ciutadania, que facilita els serveis a la comunitat aportant els mitjans de difusió adequats per a la iniciativa. Des de l'assignatura, i amb l'objectiu de la millora bioclimàtica dels espais públics i la qualitat de vida dels ciutadans, s'aposta per la incorporació dels objectius de desenvolupament sostenible com a base teòrica i projectual, principalment els vinculats a salut i benestar, Ciutats i comunitats sostenibles i Acció pel clima. A més, els estudiants incorporen, en la mesura que sigui possible, altres aspectes vinculats al Treball decent i creixement econòmic o Producció i consum responsables. Les propostes realitzades responen, a més, a les necessitats expressades per la ciutadania i/o el consistori. Entre els objectius de la metodologia no simplement s'estableix un intercanvi d'informació o demandes entre universitat i ciutadania, sinó que els treballs realitzats a l'aula es constitueixin com una guia bàsica, amb una sèrie d'idees i línies estratègiques d'intervenció, que acabin formalitzant-se en major o menor grau als municipis on es treballa. Els resultats són presentats pels estudiants en diferents actes públics locals, mitjançant publicacions específiques per a cada localitat i mitjançant breus vídeos inclosos a les webs municipals. Gràcies a això, els veïns han tingut l'oportunitat de visualitzar, analitzar i aprendre de les solucions proposades, traslladant-ne les inquietuds i les preocupacions, així com els alumnes d'explicar les seves propostes més enllà de les aules, en un gratificant intercanvi de visions. Per acabar, cal destacar que en alguns casos s'han començat a formalitzar les idees o projectes realitzats a les aules gràcies a la participació dels Ajuntaments en convocatòries públiques de subvencions per a la millora de l'espai públic dels municipis. Society must provide a holistic approach to the problems of the planetary crisis, addressing them in a multiactor, multisectoral, multidimensional, multiscalar and multidisciplinary manner. Our subject promotes these issues through bioclimatic criteria through the critical analysis of social problems and needs in populations through direct contact with the physical environment and its neighbors. This aspect is key to carrying out the objectives of the Spanish Urban Agenda, evidencing the importance of these issues and the close relationships between the approaches carried out by our SL methodology and the reality of our municipalities. Thus, this new strategic framework becomes a fundamental tool so that many student proposals can be built. La sociedad debe dotar de un enfoque holístico los problemas de la crisis planetaria, abordándolos de forma multiactor, multisectorial, multidimensional, multiescalar y multidisciplinar. Nuestra asignatura promueve estas cuestiones a través de criterios bioclimáticos mediante el análisis crítico de problemas y necesidades sociales en las poblaciones a través del contacto directo con el medio físico y sus vecinos. Este aspecto resulta clave para llevar a cabo los objetivos de la Agenda Urbana Española evidenciando la importancia de estas cuestiones y las estrechas relaciones entre los planteamientos llevados a cabo por nuestra metodología ApS y la realidad de nuestros municipios. Así, este nuevo marco estratégico se convierte en herramienta fundamental para que muchas propuestas de los alumnos puedan construirse.
