1. Habitat use, fruit consumption, and population density of the black-headed night monkey, Aotus nigriceps, in southeastern Peru
ABSTRACT The black-headed night monkey, Aotus nigriceps, has one of the largest distribution ranges of the 11 night monkey species found across Central and South America. Yet, only three studies have focused on their ecology, describing considerable variation in habitat, group composition, and population density. Therefore, we analyzed habitat use, group com

2. Checklist of the flora in ironstone outcrops at the Urucum Plateau, Corumbá, Mato Grosso do Sul
Resumo: As cangas são afloramentos ferruginosos que ocorrem ao sopé do Maciço do Urucum, na Borda Oeste do Pantanal, Corumbá-MS. No Brasil, o conhecimento sobre a florística e ecologia das comunidades vegetais associadas a essas formações ainda é incipiente. Esses habitats estão entre os mais ameaçados e menos estudados do Brasil, devido à sua ass

3. Eco-hidrologia integrada ao manejo dos recursos hídricos em áreas úmidas: caso do Banhado do Taim, RS
RESUMO A eco-hidrologia busca integrar os conhecimentos da hidrologia aos da ecologia, criando uma abordagem mais ampla para a compreensão da dinâmica dos recursos hídricos, facilitando o planejamento e as ações de programas de gestão. Uma das formas de integrar hidrologia à ecologia é por meio da elaboração de índices de adequabilidade de hábita

4. Global panorama of studies about freshwater oligochaetes: main trends and gaps
Abstract Freshwater oligochaetes have been studied over the years in a wide range of habitats around the world. To analyse the data published about freshwater oligochaetes in the 31 year period between 1985 and 2015, we searched for documents in the ISI Web of Science, Scopus and SciELO databases. A total of 979 works were evaluated from 184 periodicals. The

5. Abiotic effects on the cover and richness of corticolous lichens on Araucaria angustifolia trunks
ABSTRACT Lichens play a key role in natural ecosystems, as they can function as primary producers, recycle minerals and fix nitrogen. Despite their environmental importance, little is known about lichen ecology in Brazil, and especially about how abiotic factors may influence their spatial distribution. In this study, we aimed to verify how the cover and ric

6. Relating flight initiation distance in birds to tropical dry forest restoration
ABSTRACT Flight initiation distance (FID), defined as the distance at which an individual flees from an approaching predator, might depend on how the individual perceives the risk of being predated. Using a standardized walking approach method on focal bird individuals, we investigated whether different levels of vegetation cover (habitat) influence the perc

7. Flesh flies (Diptera: Sarcophagidae: Sarcophaginae) from the Colombian Guajira biogeographic province, an approach to their ecology and distribution
ABSTRACT Sarcophaginae is the most diverse subfamily of Sarcophagidae with 51 genera and more than 1,800 species and it is widely distributed in the Neotropical Region. Sarcophaginae flies of forest, rural, and urban habitats of the seven departments comprising the Colombian Guajira biogeographic province were surveyed. Van Someren Rydon traps baited with fe

8. Floral and reproductive biology of Alcantarea nahoumii (Bromeliaceae), a vulnerable endemic species of the Atlantic Forest
ABSTRACT Alcantarea nahoumii occurs exclusively in the state of Bahia, Brazil, and is classified as vulnerable due to deforestation and frequent fires in the region. Knowledge of floral and reproductive biology is fundamental to understanding ecological interactions, as well as the reproductive success of plant species. The objective of this study was to eva

9. The trophic niche of Mesoclemmys vanderhaegei (Testudines: Chelidae): evidence from stable isotopes
ABSTRACT Ecological niche is the multidimensional space comprising the resources used by an organism. Intraspecific variation in resource exploitation is common in reptile populations to maximize coexistence of individuals. The use of stable isotope analysis is an effective tool when there are variations in resource exploitation, since it can provide quantit

10. Differences between caves with and without bats in a Brazilian karst habitat
ABSTRACT. Since bats shelter in roosts during their period of diurnal inactivity, the quality and availability of roosts are important aspects of their ecology. Karst areas have great potential for the availability of day roosts, since they form caves, which serve as bat shelters. Here we characterize the caves used by bats in a preserved karst area of South

11. Feeding ecology of two sympatric species of large-sized groupers (Perciformes: Epinephelidae) on Southwestern Atlantic coralline reefs
RESUMO A garoupa e o badejo-verdadeiro são predadores oportunistas de grande porte, com estratégia de emboscada, comumente encontrados em recifes tropicais do Atlântico Sul. A dieta das duas espécies foi investigada, avaliando influências ontogenéticas, espaciais e temporais, assim como a sobreposição no uso de recursos entre estes dois predadores co

12. Protocol for collecting Mutillidae (Hymenoptera, Aculeata) in ecological studies: species-area effects on Mutillidae communities
ABSTRACT The species-area relationship is one of the most consistent patterns in ecology, and fragmentation is a major cause of habitat loss. Environmental changes in a site can affect the spatial distribution of organisms. Knowledge of Mutillidae ecology is still scarce due to the lack of standardized sampling. Our aim was to: (1) determine the effect of ha
