Pollution, habitat loss, fishing, and climate change as critical threats to penguins
(Wiley, 2015)
Cumulative human impacts across the world's oceans are considerable. We therefore examined a single model taxonomic group, the penguins (Spheniscidae), to explore how marine species and communities might be at risk of ...
Can network metrics predict vulnerability and species roles in bird-dispersed plant communities? Not without behaviour
(Wiley-Blackwell, 2020-02-01)
Network metrics are widely used to infer the roles of mutualistic animals in plant communities and to predict the effect of species' loss. However, their empirical validation is scarce. Here we parameterized a joint species ...
A família Orchidaceae e as mudanças climáticas da Mata Atlântica
(Universidade Federal de São CarlosUFSCarPrograma de Pós-Graduação em Diversidade Biológica e Conservação - PPGDBC-SoCâmpus Sorocaba, 2014-05-30)
The Atlantic Forest, located in Brazil, has one of the highest levels of biodiversity and endemism on the planet, mainly due to the variety of vegetation types associated with the various types of soil, topography and ...
Immigration and establishment of Trypanosoma cruzi in Arequipa, Peru.
(Public Library of Science, 2019)
Changing environmental conditions, including those caused by human activities, reshape biological communities through both loss of native species and establishment of non-native species in the altered habitats. Dynamic ...
Forest and connectivity loss drive changes in movement behavior of bird species
(2020-08-01)
In a rapidly changing world, it is important to understand how environmental modifications by humans affect species behavior. This is not a simple task, since we need to deal with a multitude of species and the different ...
Stochastic species loss and dispersal limitation drive patterns of spatial and temporal beta diversity of fish assemblages in tropical agroecosystem streams
(2020-01-01)
Beta diversity quantifies changes in assemblages among sites and can identify how anthropogenic changes affect species distributions patterns. We investigated how spatial and temporal beta diversity of fish assemblages ...
Additions to the checklist of Scoliidae, Sphecidae, Pompilidae and Vespidae of Peru, with notes on the endemic status of some species (Hymenoptera, Aculeata)
(Pensoft Publ, 2015-01-01)
The first checklist of the Peruvian Hymenoptera listed 1169 species and subspecies of aculeate wasps, including 173 species of Pompilidae, seven of Scoliidae, 39 of Sphecidae and 403 of Vespidae. Herein are reported 32 ...
Distribuição espacial, composição taxonômica e diversidade funcional de copepoda em águas doces do estado de São Paulo
(Universidade Federal de São CarlosUFSCarPrograma de Pós-Graduação em Ecologia e Recursos Naturais - PPGERNCâmpus São Carlos, 2021-05-14)
Copepods are important components of freshwater zooplankton, acting as a connection between communities, feeding on small microorganisms, algae and other invertebrates and themselves serving as food for similar invertebrates, ...
Evaluation of biodeterioration and the dynamic modulus of elasticity of wood in ten fast-growing tropical species in costa rica exposed to field testing
(Statny Drevarsky Vyskumny Ustav, 2015)
In tropical regions, it is possible to produce a large variety of timber species in plantation conditions. However, wood from these trees has low natural durability. Biodeterioration and the dynamic modulus of elasticity ...
A multi-species assessment of post-dispersal seed predation in the central Chilean Andes
(OXFORD UNIV PRESS, 2006-07)
Background and Aims Post-dispersal seed predation in alpine communities has received little attention despite evidence that seeds removed by granivores can decrease plant recruitment into ecosystems. Moreover, few studies ...
