Pervasive gaps in Amazonian ecological research

Biodiversity loss is one of the main challenges of our time,1,2 and attempts to address it require a clear un derstanding of how ecological communities respond to environmental change across time and space.3,4 While the increasing availability of global databases on ecological communities has advanced our knowledge of biodiversity sensitivity to environmental changes,5–7 vast areas of the tropics remain underst...

Mirmecofauna em um fragmento de floresta atlântica urbana no município de Maríl...

Made available in DSpace on 2022-04-28T18:56:53Z (GMT). No. of bitstreams: 0 Previous issue date: 2011-05-01; The aim of this study was to verify the influence of the habitat fragmentation on the Ant Fauna in an urban fragment of Semideciduous Seasonal Atlantic Forest located in the municipality of Marília, São Paulo, Brazil. The studied fragment was divided into three environments in relation to edge: Edge (2m...

Caterpillars’ natural enemies and attack probability in an urbanization intensi...

Made available in DSpace on 2022-05-01T05:29:25Z (GMT). No. of bitstreams: 0 Previous issue date: 2021-09-01; Intensification of urbanization has been shown to be associated with taxonomic and functional modifications of biological communities, leading to changes in trophic interactions. These changes may reduce the delivery of ecosystem services provided by urban ecosystems. For instance, predation on herbivor...

Vulnerability of micro-regions within Northeast Brazil to the new coronavirus (...

Report from “Observatório COVID19 - Grupo: Redes de Contágio – Laboratório de Estudos de Defesa” for the Northeast Region of Brazil. We combined data on confirmed cases of the new coronavirus (SARS-CoV-2) as reported by public authorities by 02/04 and structural analyses of road transport networks within and between the nine States of Northeast Brazil to predict the potential influence of the 187 micro-regions ...

Small vertebrates are key elements in the frugivory networks of a hyperdiverse ...

Made available in DSpace on 2020-12-12T02:45:01Z (GMT). No. of bitstreams: 0 Previous issue date: 2020-12-01; The local, global or functional extinction of species or populations of animals, known as defaunation, can erode important ecological services in tropical forests. Many mutualistic interactions, such as seed dispersal of large seeded plants, can be lost in large continuous forests due to the rarity of l...

Forest cover and landscape heterogeneity shape ant–plant co-occurrence networks...

Made available in DSpace on 2019-10-06T16:56:32Z (GMT). No. of bitstreams: 0 Previous issue date: 2019-01-15; Fundação de Amparo à Pesquisa do Estado de São Paulo (FAPESP); Context: The effects of habitat loss and fragmentation on biodiversity involve a series of mechanisms and processes that cannot be studied in isolation, mainly because human-modified landscapes are spatially heterogeneous. Despite the recent...

Forest cover drives leaf litter ant diversity in primary rainforest remnants wi...

Made available in DSpace on 2019-10-06T16:17:51Z (GMT). No. of bitstreams: 0 Previous issue date: 2019-04-15; Conselho Nacional de Desenvolvimento Científico e Tecnológico (CNPq); The main effects of habitat loss and fragmentation have been addressed through changes in diversity patterns at different spatial levels. Species richness and diversity are the most used descriptors to assess the effect of changes in ...

Equal but different: natural ecotones are dissimilar to anthropic edges

Increasing deforestation worldwide has expanded the interfaces between fragmented forests and non-forest habitats. Human-made edges are very different from the original forest cover, with different microclimatic conditions. Conversely, the natural transitions (i.e., ecotones) are distinct from human-made forest edges. The human-made forest edges are usually sharp associated with disturbances, with abrupt change...

Mirmecofauna em um fragmento de floresta atlântica urbana no município de Maríl...

O objetivo deste estudo foi verificar a influência da fragmentação urbana sob a mirmecofauna de uma Floresta Atlântica Estacional Semidecidual localizada no município de Marília/SP. Para isso, o fragmento foi dividido em três ambientes em relação à distância da borda, e adicionalmente denominados de Borda, Transição e Centro. Através de armadilhas pitfall e isca atrativa, foram realizadas nove coletas durante o...
