Texto completoResumen
Estuarine floodplain wetland pools occur adjacent to marine coasts and estuaries throughout the world. In Australia’s dry tropics and sub-tropics, low and irregular rainfall means estuarine wetland pools are isolated for much of the time, resulting in varied within-pool conditions, with chemistry ranging from fresh to hypersaline, depending on the balance between freshwater and marine inputs and the time between connections. Varied physical conditions and irregular connectivity provide the potential for substantial faunal difference among pools. The present study compares the compositions and structures of the fish fauna of a broad cross section of estuarine wetland pools adjacent to the estuary of the Fitzroy River, one of the largest rivers in Australia’s dry tropical/subtropical zone. Ten pools were sampled between February 2004 and May 2005. The total species richness was low, with the 6123 fish recorded over the study, comprising only 44 species. This low species richness was reflected at the individual pool level, with a maximum total richness of 25 species in a single pool. Different pools had faunas that differed as a function of the proportion of the community comprised of marine spawned, compared with freshwater spawned, species. This was a reflection of the extent of connectivity to freshwater and marine systems, which determined both the physical nature of pools and the sources of faunal supply. Despite faunal differences among pools, at a functional level pool fish faunas were dominated by detritivores, regardless of pool type, size, season or connectedness.

Texto completoResumen
The study of Ephemeroptera, Plecoptera and Trichoptera associated with litter in southeastern Brazil streams aimed to answer the following questions: 1) Does richness and composition of EPT fauna differ between riffle and pool mesohabitats despite being associated to the same substratum, litter? 2) Does the similarity of the EPT fauna between both mesohabitats change with time? 3) Does the EPT functional feeding structure differ between both mesohabitats (riffles-pools)? In order to answer these questions, monthly collections, from November 1999 to June 2000, were done in Ribeirão (Stream) Bocaina with a D-net (10 litter patches in riffles and 10 in pools). The EPT fauna at Ribeirão Bocaina was more diversified and more abundant in the litter in riffles than in the litter in pools, although, when richness was standardized for the same number of individuals it became similar in both conditions. EPT fauna was very different between both mesohabitats in terms of faunal composition as well as in terms of function. Probably it was due to differences in water speed, in the time of litter residence and in the concentration of dissolved oxygen between both mesohabitats.

Texto completoResumen
Context After fire, immigration from outside burnt areas is important for the recovery of faunal communities. However, for recovery to occur, the matrix around the fire must support source populations of immigrants. Therefore, the landscape context of fires may be a critical determinant of the species pool available for (re)colonisation, hence post-fire community composition. Increasingly, fires occur in fragmented systems, and there is limited knowledge of how the surrounding landscape interacts with post-fire community recovery. Aim The present study aimed to examine how landscape context influences faunal communities after large wildfires. Methods Three reserves burnt by wildfire were examined ~18 months before the study in the Mallee region of south-eastern Australia. In all cases the burnt area consisted of natural mallee woodland. Two fires occurred within a matrix of extensive natural vegetation, while the third fire burnt >80% of a reserve situated within a highly fragmented, largely agricultural landscape. Birds, reptiles and mammals were surveyed at 90 sites inside and outside the fire boundaries, and relationships of species occurrence to reserve location, burnt versus unburnt status and distance from fire edge were all examined. Key results Post-fire faunal communities reflected the species in the surrounding unburnt landscape. Notably, open habitat specialists, invasive species and species that can persist in small habitat patches were prominent within the fragmented system. Post-fire fauna communities were also influenced by variation of the natural vegetation surrounding the fire. The occurrence of species with low dispersal ability (i.e. reptiles) was influenced by local (patch scale) vegetation structure. 2Conclusions The landscape context of fires is a major driver of the composition of post-fire faunal communities. Our results highlight the potential loss of species sensitive to fragmentation from fire-prone natural vegetation within modified landscapes, and that a reduced pool of potential immigrants leads to ‘attenuated succession’, compromising recovery of the pre-fire community. Implications Post-fire colonists reflect the surrounding landscapes species pool, such that reserves surrounded by fragmented or otherwise low quality habitat are at risk of attenuated succession after fire. Landscape context should be incorporated into conservation planning in fire-prone ecosystems, including consideration of surrounding habitat quality and connectivity and protecting long unburnt vegetation.

Planting Mangroves in the ponds of PT Antam Tbk UBPP Logam Mulia, Pulogadung, Jakarta, is one of the environmental management activities in the reforestation area as a form of social and environmental responsibility. The existence of mangrove plants in ponds which have reached the age of 2 years recently, could have an ecological impact. Field observations were made by measuring the type and density of flora in the pond by census, and the frequency of biological encounters based on time search for fauna. The results showed that there were 4 types of plants in the ponds, namely mangrove (Rhizophora mucronata), lotus (Nymphaea lotus), needle grass (Adropogon aciculatus), and Moss (Taxiphyllum barbieri). Identified as many as 11 species of fauna, 5 species of insects, 1 species of aves, 1 species of macro benthic, and 3 species of fish. The diversity index of flora and fauna in the ponds was still in the low category (H' < 1). The growth of R. mucronata type mangroves aged 2 years in ponds reached an average height of 47 cm with a diameter of 1.3 cm, with a total biomass of 36.77 kg and contributed to absorbing CO2 of 54.41 kg or 5.4 ton/ha. Biodiversity in the pond ecosystem of PT Antam Tbk UBPP Logam Mulia has the potential to continue to grow and contribute to carbon sequestration.Keywords: Pool; Mangroves; Biodiversity; Rhizophora mucronataABSTRAKKeanekargaman Hayati Ekosistem Kolam Mangrove Kawasan PT Antam Tbk.

Lying at the southernmost point of the Lucayan Archipelago, the Turks and Caicos Islands are amongst the better studied localities for anchialine cave biodiversity. For nearly five decades, novel invertebrate fauna, comprised primarily of crustaceans, have been collected from these tidally influenced pools – but new findings are always on the horizon. Herein we present new records of crustaceans and annelids from anchialine blue holes and horizontal caves of the Turks and Caicos. These findings include two potentially new species of meiofaunal annelids and a new species of remipede collected from a shallow water cave pool. Our 2019 expedition additionally expands known faunal distributions for several taxa across the Caicos islands, and raises the biodiversity of the region to 35 species, 13 of them considered endemic. This is the first comprehensive faunal list for the anchialine systems in the Caicos Bank.

Texto completoResumen
AbstractThe Upper Famennian (Upper Devonian) Strud locality has yielded very abundant and diversified flora as well as vertebrate and arthropod faunas. The arthropod fauna, mostly recovered from fine shales deposited in a calm, confined floodplain habitat including temporary pools, has delivered a putative insect and various crustaceans including eumalacostracans and notostracan, spinicaudatan and anostracan branchiopods. Here we present the Strud eurypterids, consisting of semi-articulated juvenile specimens assigned to Hardieopteridae recovered from the pool and floodplain deposits, as well as larger isolated fragments of potential adults recovered from stratigraphically lower, coarser dark sandy layers indicative of a higher-energy fluvial environment. The Strud fossils strongly suggest that, as proposed for some Carboniferous eurypterids, juvenile freshwater eurypterids inhabited sheltered nursery pools and migrated to higher-energy river systems as they matured.

Texto completoResumen
Macroinvertebrates are a crucial component of wetland trophic webs. Many taxa are used as bioindicators of ecosystem change. However, relationships between macroinvertebrates and the environmental factors in peat pool habitats are still not well recognized. The present study shows the results of long-term studies during the years 2010–2020, on the responses of macroinvertebrates to the changes of environmental variables in a peat pool habitat formed as a result of peat exploitation on continental raised bog. The RDA analysis significantly explained 87.3% of the variance in macroinvertebrates abundances. Assemblages of most taxa (Anisoptera, Chironomidae, Ceratopogonidae, Coleoptera, Hydrachnidia and Tabanidae) showed a strong relationship with N-NO3 and pH. Moreover, densities of Chaoboridae larvae were explained by chlorophyll-a concentrations. Dominant taxon, Chironomidae, constituted from 48% to 87% of total faunal density. The highest proportions showed larvae of Psectrocladius sp. (gr. sordidellus) and Chironomus sp. Changes in the composition of macroinvertebrate fauna over a period of 10 years reflect the eutrophication process of the peat pool and deterioration of habitat conditions.

AbstractThe helminth fauna of 291 Hemidactylus mabouia (Lacertilia: Gekkonidae) from a rock outcrop area in the state of São Paulo, Southeastern Brazil, was studied. Five species were recovered, namely one unidentified species of centrorhynchid acanthocephalan (present only as cystacanths) and the nematodes Parapharyngodon sceleratus, P. largitor (Oxyuroidea: Pharingodonidae), Physaloptera sp. (Spiruroidea: Physalopteridae) and one indeterminate species of Acuariidae (Acuaroidea), with the latter two forms present only as larvae. Infection rates tended to increase with host size, but appeared to be unaffected by season. Hemidactylus mabouia shared most of its helminth fauna with two other sympatric lizard hosts, Mabuya frenata and Tropidurus itambere. The helminth assemblage of the H. mabouia population appears to have been entirely acquired by this exotic gecko from the local helminth species pool, rather than possessing any species from the parasite faunas of the original African populations.

Previous research has shown that a range of physical and biological drivers can influence the composition of faunal assemblages occupying localities within streams. There is much debate in the literature about which of these is more important. Descriptive and experimental field studies were conducted in two relatively undisturbed, second order rainforest streams in southeast Queensland, Australia. The principal objectives were to describe spatial and temporal patterns in pool fauna and explore relationships between these patterns and physical attributes of habitat, disturbance and biotic interactions. The macroinvertebrate and vertebrate fauna of 12 small stream pools were sampled approximately monthly over a period of 15 months. Samples were collected from all major within-pool habitat types and concurrent measurements of potentially important environmental parameters were made at landscape scales of stream, pool and habitat patch. Faunal assemblages were consistently different between the two streams and between the various within-pool habitat types, although the latter may partially be explained by differences in sampling protocols applied in the different habitat types. However, spatial and temporal variation in faunal assemblages within habitat types was large at the scales of whole pools and within-pool habitats, and this variation occurred apparently independently of variation in physical habitat attributes. These results indicated that very little of the local scale faunal variation could be explained by abiotic drivers and that some other factors must be responsible for the observed faunal patterns. Previous research had indicated that atyid shrimps can play a significant ecological role in rainforest streams, where they act as 'ecosystem engineers' by removing fine sediment from hard surfaces. This subsequently alters algal dynamics and faunal composition in streams. A pool-scale manipulative experiment was conducted to investigate the role of the atyid Paratya australiensis, which is an abundant and conspicuous component of the fauna. Removal of shrimp from pools had no effect on sediment accrual on hard surfaces and consequently did not affect algal biomass or faunal assemblages. The lack of effect on sediment accumulation was attributed to the low rate of deposition in these streams, which was an order of magnitude lower than in streams where atyids have been demonstrated to play a keystone role. The fish Mogurnda adspersa was found to be the primary predator of pool fauna in the study streams, where it preyed on a wide variety of taxa. Dietary analyses revealed that an ontogenetic shift occurred in both diet and the within-pool habitat where fish fed. Within this general framework, individual fish had strong individual prey preferences. Significant correlations were found between the natural abundance of Mogurnda in pools and faunal assemblage patterns in both gravel habitat and pools in general, indicating that predation had an effect on pool fauna. The nature of this effect varied between habitats. A direct density dependent response was observed in gravel habitat. In contrast, the response in pools varied considerably between individual pools, perhaps reflecting the differing prey preferences of individual fish. Despite these correlations, an experimental manipulation of the density of Mogurnda at a whole-pool scale did not conclusively identify a predation effect. This may have been due to problems with fish moving between treatments, despite attempts to constrain them, and low experimental power due to the inherent high variability of pool fauna. Overall, the results of the study indicated that there was considerable spatial and temporal variation in pool fauna despite similarities in the physical attributes of pools and their close proximity. This variation appeared to occur at random and could not be explained by abiotic or biotic factors. Predation had a small effect, but could not explain the overall patterns, whereas disturbance by spates had very little effect at all. Stochastic processes associated with low level random recruitment were identified as a possible and plausible explanation for observed patterns. These conclusions are discussed in terms of their implications for our understanding of the ecology and management of streams.

Previous issue date: 2013-03-26The approval of Historical Memory Law happened in a time of troubled political and social regarding the memories of the victims of the Spanish Civil War and and Francoism. This complaint about the losers memories has been treated since the Democratic Transition, started after Francisco Franco s death in 1975. Cinema, as cultural demonstration, was used throughout all Francoism either to legitimate the State speeches or to contest them. With the consolidation of democracy in Spain, it was not different: many film productions continued building their own narratives about the recent past of the country. Thus, the present term paper aims at analyzing how the films Silencio Roto (Montxo Armend?riz, 2001) and El Laberinto del Fauno (Guillermo del Toro, 2006), through the respective representations about the Francoist repression against guerrilla Maquis in the first years of the Spanish dictatorship, they acquire other meanings when analyzed in their corresponding production contexts. Through the film analysis, it was searched in the intrafilmic elements (present representations in the sequences, scenes and characters) and extrafilmic analysis (details about the production and its context) evidences about the movie makers positioning regarding Duty of Memory in Spain. From this point, conter-analysis has allowed inserting both films in the political and social debate about the dispute of memories in Spain in the 2000s. The importance of this research lies in the usage of film source as an analysis object, as well as its approach with questions regarding Memory areas which allow a narrative juxtaposition with historiography.
A aprova??o da Lei de Mem?ria Hist?rica deu-se em meio a conturbados debates pol?ticos e sociais sobre as mem?rias das v?timas da Guerra Civil espanhola e do Franquismo. Essa querela sobre as recorda??es dos perdedores vem sendo tratada desde a Transi??o Democr?tica, iniciada ap?s a morte de Francisco Franco, em 1975. O cinema, enquanto manifesta??o cultural, foi utilizado ao longo de todo o Franquismo ora para legitimar os discursos do Estado, ora para contest?-lo. Com a consolida??o da democracia na Espanha, n?o foi diferente: muitas produ??es f?lmicas continuaram construindo narrativas pr?prias sobre o passado recente do pa?s. Neste sentido, a presente disserta??o tem como objetivo analisar de que forma os filmes Silencio Roto (Montxo Armend?riz, 2001) e El Laberinto del Fauno (Guillermo del Toro, 2006), atrav?s de suas respectivas representa??es sobre a repress?o franquista contra a guerrilha Maquis nos primeiros anos da ditadura espanhola, adquirem outros significados quando analisados em seus correspondentes contextos de produ??o. Atrav?s da an?lise f?lmica, buscou-se nos elementos intraf?lmicos (representa??es presentes nas sequ?ncias, cenas e personagens) e extraf?lmicos (detalhes sobre a produ??o e seu contexto) evid?ncias sobre os pr?prios posicionamentos dos cineastas com rela??o ao Dever de Mem?ria na Espanha. A partir disso, a contra-an?lise possibilitou inserir ambas as pel?culas no debate pol?tico e social sobre a disputa de mem?rias na Espanha dos anos 2000. A import?ncia desta pesquisa reside na utiliza??o da fonte f?lmica enquanto objeto de an?lise, bem como sua aproxima??o com as quest?es relativas ? Mem?ria ?reas que possibilitam uma justaposi??o narrativa com a pr?pria historiografia.

Hernandez, Perez Sara. "Que faut-il choisir entre une gestion centralisée et un système d’autogestion base sur des mécanismes de marché pour réduire le trafic illégal des espèces faunistiques sauvages : analyse comparative économique et institutionnelle appliquée aux tortues marines en Colombie". Thesis, Paris 10, 2012. http://www.theses.fr/2012PA100206/document.
Texto completoResumen
Depuis plus de 30 ans, la Colombie construit sa politique de préservation des espèces faunistiques et de lutte contre le trafic illégal de ces espèces. Ce cadre institutionnel national s’est vu renforcé par la ratification de la convention CITES (Convention sur le commerce international des espèces de la flore et de la faune sauvages menacées d’extinction) en 1981. Pourtant, ce cadre institutionnel ne suffit pas à infléchir sur le trafic illégal des tortues marines en Colombie. L’analyse des failles du mode de régulation de type « commande et contrôle » montre les limites de l’intervention de l’Etat comme seul modèle possible à gérer le trafic illicite de tortues marines. D’où ma proposition de concevoir et mettre en place un mécanisme de quotas négociables de tortues marines décroissants dans le temps, renforcé par arrangements contractuels. Cette thèse a pour objectif de comparer l’efficacité de ces deux modes de gouvernance à réduire le trafic illégal de tortues marines, du point de vue la performance environnementale, de l’efficacité économique et de l’équité sociale. J’ai évalué les coûts de transactions pour démontrer que la variation dans la structure des coûts de transactions et la distribution de ces coûts auprès des acteurs concernés influent sur la performance finale du cadre institutionnel. Une analyse coûts-avantage a été réalisée pour justifier d’un changement institutionnel, en complément de l’analyse des coûts de transactions. Cette étude s’est situe au nord de la Colombie, sur un territoire de 30 km, territoire des indigènes Wayùu, étant le plus concerné par le trafic illégal de tortues vertes (Chelonia mydas) et tortues à écailles (Eretmochelys imbricata)For over 30 years, Colombia built its national policy to protect wildlife species against the illegal traffic. The national institutional framework was strengthened by the ratification of the CITES (Convention on International Trade in Endangered Species of flora and fauna threatened with extinction) in 1981. However, this institutional framework is not sufficient to curb the illegal trade of marine turtles species. Despite some success to protect and recover some species, what really matters is the effectiveness of the national policy to conserve wildlife species. Hence my proposal to design and implement a cap and trade system based on transferable quotas decreasing in time, reinforced by contractual arrangements. This self-organized system aims at having zero catches level and enhance conformity and cooperation within the environmental regulation. This thesis aims to compare the efficacy of these two modes of governance to reduce the illegal trade of sea turtles based on the following criteria: the environmental performance, economic efficiency and social equity. I pursuit by estimating the corresponding transaction costs to show that the variation in the structure of transaction costs and the distribution of these costs among stakeholders affect the final performance of the institutional framework. Cost-benefit analysis was performed to justify institutional change, in addition to the analysis of transaction costs. This study is located in the north of Colombia, an area of 30 km, indigenous Wayuu territory, being more concerned with the illegal green turtles (Chelonia mydas) and hawksbill (Eretmochelys imbricata)

Texto completoResumen
Detailed research into marsupial behavioural ecology and modelling of past Aboriginal exploitation of terrestrial fauna has been scarce. Poor bone preservation is one limiting factor in Australian archaeological sites, but so has been the lack of research concerning the ecology and physiology of Australia’s endemic fauna. Much research has focused on marine and fresh-water shell-fish found in coastal and inland midden sites. Detailed studies into areas such as seasonality of past human occupation and nutritional returns from terrestrial prey species have not had the same attention. This chapter reviews the current level of published Australian research into two aspects of faunal studies, seasonality and nutrition. It describes the patterns from well-researched faunal data excavated from the Ice Age sites in southwest Tasmania. Concentration is on the vertebrate fauna found in seven limestone cave sites to examine any temporal changes to seasonal butchery and identify any differences between seasonally occupied sites.

Texto completoResumen
Abstract This chapter discusses the ecology and biogeography of nematodes from freshwater environments that are extreme in temperature, chemical composition, variability, or isolation. Described and compared are the compositions of nematode faunas from hot or mineral springs, pools and bogs in polar regions, intermittent lakes or pools or streams, freshwater pools in bromeliads or tree hollows, stemflow, fresh groundwaters, and caves. Comparisons of the nematode faunas from these extreme habitats with those from more typical freshwater environments are also provided. Also discussed are nematodes with evolutionary affinities to freshwaters that are found in estuarine sediments along with nematodes from freshwaters with evolutionary affinities to otherwise marine taxa. The emphasis is on broad ecological patterns rather than on detailed species interactions with the various freshwater environments. Thus, the chapter focuses on genera or higher taxa rather than species.

Abstract This chapter provides a checklist for the family Mymaridae. It provides information on species diversity, host records, distribution records by province in Iran, as well as world distribution. Comparison of the mymarid fauna of Iran with adjacent countries indicates that the fauna of Russia (104 species) is much greater than that of Iran (33 species), followed by Turkey (19 species), Turkmenistan (11 species), Pakistan and United Arab Emirates (five species) and Iraq and Oman (both with one species); no species have been recorded from the other eight neighbouring countries. However, the much fewer number of species recorded from countries other than Russia, including Iran, certainly results from inadequate sampling and poor taxonomic study. Russia shares the highest number of known species with Iran (21 species), followed by Turkey (11 species), Turkmenistan (one species), Pakistan (two species) and Iraq, Oman, United Arab Emirates and the former USSR (each with one species).

Texto completoResumen
AbstractOceanic islands are usually difficult for mammals to colonize; consequently, the native mammal fauna is typically species-poor, often consisting of just a few species of bats. The oceanic islands of the Gulf of Guinea are no exception to this pattern. Still, the known mammal richness is relatively high for the small size of the islands. Out of a total of 13 native species, including 11 bats and 2 shrews, at least 7 species and 3 subspecies are single-island endemics. In addition to native species, at least 6 other wild mammals have been introduced to the islands purposely or accidentally by humans. Some of these are among the world’s most notorious invasive species and cause damage to native species, ecosystems, and humans. Predation by exotic species can threaten native island mammals, which are especially sensitive due to their small populations and limited ranges. These impacts are likely worsened by other threats, such as forest degradation and climate change, and a general lack of knowledge about the natural history of most species also hampers the implementation of conservation measures. Therefore, fostering further research on the endemic-rich mammal fauna of these islands is vital to ensure their persistence.

<em>Abstract</em>.—This chapter provides a listing of fishes known to be present in the Mississippi River from the headwaters at Lake Itasca, Minnesota to the Gulf of Mexico terminus. A total of 188 species are presently known from the Mississippi River, including 3 diadromous species and 17 nonnative species that have established self-sustaining populations in one or more reaches of the Mississippi River. Species are classified into three relative abundance categories and noted as residents, peripherals, introduced (established nonnatives), or strays (introduced but not established). The diversity of fishes varies longitudinally with 78 species in the reach from the headwaters to St. Anthony Falls; 113 and 105 species in the upper (Upper St. Anthony Lock and Dam to Pool 13) and lower (Pools 14–26) impounded reaches, respectively; and 121 and 136 species in the upper (Missouri River confluence to Ohio River confluence) and lower (Ohio River to the Gulf of Mexico outlet) free-flowing reaches, respectively. Although the composition of the Mississippi River fish fauna has changed little despite more than 80 years of habitat alteration, the extirpation of five species in individual reaches of the river may be a forewarning of a system losing resiliency and indicate the need for habitat conservation and rehabilitation to conserve the biodiversity of North America’s largest river.

Texto completoResumen
The city of Guayaquil presents a constant economic growth and therefore a high demand for human labor, which leads to national migration from areas with lower labor supply, to the city, this generates an accelerated urban development and a high capital gain in consolidated areas of the city, so that the new inhabitants especially poor people to be forced to look for a habitat, and not having access to housing in a consolidated area with all basic services, seek areas with informal settlements whose cost are affordable for such dwellers.The objective of this study will be to generate a strategic mitigation plan for the environmental impact, taking as a study base the informal settlements on the papagayo protective forest in the northwest of Guayaquil.In this work, i have made a diagnosis of the current state of the Papagayo protective forest was made, in which information on the flora and fauna of the area was compiled and classified according to the level of affectation to which it has been subjected, in addition to the impact generated by informal settlements that directly affect the study area. Based on the study of concepts and theories of human settlements, environmental impacts, quantification of activities developed by the population through land use and parceling of the territorial surface affected by human settlements on the Papagayo Protected Forest using the ARCGIS geographic information system, complemented with the Analytical Hierarchy Process (AHP), a tool that facilitates complex decision making, which allows establishing the impact levels of flora and fauna, obtaining mitigation strategies for the environmental impact, improving the quality of life of its inhabitants and increasing the green area index of the area.
