1. Predicting the potential distribution of aquatic herbaceous plants in oligotrophic Central Amazonian wetland ecosystems
ABSTRACT Aquatic herbaceous plants are especially suitable for mapping environmental variability in wetlands, as they respond quickly to environmental gradients and are good indicators of habitat preference. We describe the composition of herbaceous species in two oligotrophic wetland ecosystems, floodplains along black-water rivers (igapó) and wetlands upo

2. Gestão socioambiental nas grandes cidades: por que olhar do Brasil para as iniciativas das megalópoles indianas?
Resumo Diante dos diversos modelos de gestão pública no mundo, é valido observar outras experiências em realidades socioambientais mais semelhantes às cidades brasileiras em desenvolvimento. No cenário do BRICS – Brasil, Rússia, Índia, China e África do Sul –, o presente texto identifica as três maiores cidades indianas, Mumbai, Déli e Bangalo

3. Habitat, limnological signatures and spatial modeling: a zoning proposal for the Curuá-Una hydroelectric reservoir, Pará, Brazil
Resumo Objetivo O objetivo deste trabalho é caracterizar, modelar espacialmente e realizar o zoneamento do ambiente aquático no reservatório da UHE de Curuá-Una, no estado do Pará, na Amazônia brasileira. Métodos Os dados foram coletados em 77 pontos amostrais distribuídos em 20 transectos no reservatório de Curuá-Una, no mês de novembro de 20

4. Wild pig (Sus scrofa L.) occupancy patterns in the Brazilian Atlantic forest
Resumo: Apesar dos grandes impactos da invasão do javali (Sus scrofa) nos ecossistemas naturais, o uso de hábitats por esta espécie nos neotrópicos ainda permanece pouco estudado. Aqui, nós investigamos os efeitos do hábitat local e de covariáveis da paisagem (tipos de vegetação, cursos d'água e estradas) sobre os padrões de ocupação do javali n

5. Relationship of Neotropical otter vestiges with environmental and anthropogenic factors
RESUMO A lontra neotropical, Lontra longicaudis é um mustelídeo semiaquático que usa seu habitat de diferentes formas. Para entender a influência relativa de fatores antrópicos e ambientais sobre a distribuição de lontras neotropicais, nós conduzimos monitoramentos sistemáticos de vestígios de lontras na região do médio Rio Guamá, Pará, Amazôn

6. Ecological niche differentiation between Acanthodactylus micropholis and A. khamirensis (Sauria: Lacertidae) in southern Iran
ABSTRACT Acanthodactylus micropholis Heidari, Rastegar-Pouyani, Rastegar-Pouyani & Rajabizadeh, 2013 and A. khamirensis Blanford, 1874 are genetically and morphologically distinct, but their ecological differentiation has not previously been evaluated. The ecological niche models of these two sister species Acanthodactylus were reconstructed using climate an

7. Lizard assemblages on sandy coastal plains in southeastern Brazil: An analysis of occurrence and composition, and the role of habitat structure
Abstract Data on the structure of lizard communities in the different biomes and ecosystems of Brazil are still limited. In this study, we related the species richness, abundance and the spatial occurrence of lizards to the structure of the vegetation found on the coast of the state of Espírito Santo, southeastern Brazil, to determine whether habitat influe

8. Bryophyte richness of soil islands on rocky outcrops is not driven by island size or habitat heterogeneity
ABSTRACT The species-area relationship (SAR) is one of the oldest and most studied ecological models, having even served as the foundation of the Theory of Island Biogeography. Nevertheless, the relative importance of habitat heterogeneity to SAR remains poorly understood. Our aim was to test the relative importance of habitat heterogeneity to the SAR of bry

9. Environmental suitability for Lutzomyia longipalpis in a subtropical city with a recently established visceral leishmaniasis transmission cycle, Argentina
BACKGROUND Visceral leishmaniasis (VL) is an endemic disease in northeastern Argentina including the Corrientes province, where the presence of the vector and canine cases of VL were recently confirmed in December 2008. OBJECTIVES The objective of this study was to assess the modelling of micro- and macro-habitat variables to evaluate the urban environme

10. Climate and land-use changes effects on the distribution of a regional endemism: Melanophryniscus sanmartini (Amphibia, Bufonidae)
ABSTRACT Amphibians are the most threatened vertebrate group according to the IUCN. Land-use and land cover change (LULCC) and climate change (CC) are two of the main factors related to declining amphibian populations. Given the vulnerability of threatened and rare species, the study of their response to these impacts is a conservation priority. The aim of t

11. Habitat selection of the pink shrimp Farfantepenaeus paulensis and the blue crab Callinectes sapidus in an estuary in southern Brazil: influence of salinity and submerged seagrass meadows
This study was conducted in two estuarine inlets (Saco da Mangueira and Saco do Arraial) at the Patos Lagoon estuary, southern Brazil. The changes in relative abundance and size of post-larvae and juvenile shrimp Farfantepenaeus paulensis and juvenile blue crab Callinectes sapidus were compared, considering the influence of salinity and the presence of subme

12. Tank bromeliad water: similar or distinct environments for research of bacterial bioactives?
The Atlantic Rainforest does not have a uniform physiognomy, its relief determines different environmental conditions that define the composition of its flora and fauna. Within this ecosystem, bromeliads that form tanks with their leaves hold water reservoirs throughout the year, maintaining complex food chains, based mainly on autotrophic and heterotrophic
