Pervasive gaps in Amazonian ecological research
Carvalho, Raquel L.; Resende, Angelica F.; Barlow, Jos; França, Filipe M.; Moura, Mario R.; Maciel, Rafaella; Alves-Martins, Fernanda; Shutt, JackBiodiversity 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...

Male care status influences the risk-taking decisions in a glassfrog
Valencia-Aguilar, Anyelet [UNESP]; Rodrigues, Domingos de Jesus; Prado, Cynthia P. A. [UNESP]Made available in DSpace on 2020-12-10T20:02:32Z (GMT). No. of bitstreams: 0 Previous issue date: 2020-06-16; Fundação de Amparo à Pesquisa do Estado de São Paulo (FAPESP); Parental care increases offspring survival, but may impose costs by decreasing adult survival or mating opportunities. Because individuals have limited resources, time allocation and risk decisions are expected to vary according to the care ...
Rarity of monodominance in hyperdiverse Amazonian forests
ter Steege, Hans; Henkel, Terry W.; Helal, Nora; Marimon, Beatriz S.; Marimon-Junior, Ben Hur; Huth, Andreas; Groeneveld, Jürgen; Sabatier, DanielMade available in DSpace on 2020-12-12T01:40:04Z (GMT). No. of bitstreams: 0 Previous issue date: 2019-12-01; Coordenação de Aperfeiçoamento de Pessoal de Nível Superior (CAPES); Tropical forests are known for their high diversity. Yet, forest patches do occur in the tropics where a single tree species is dominant. Such “monodominant” forests are known from all of the main tropical regions. For Amazonia, we sam...
Dismantling Brazil's science threatens global biodiversity heritage
Fernandes, G. Wilson; Vale, M. M.; Overbeck, Gerhard Ernst; Bustamante, Mercedes M.C.; Grelle, Carlos Eduardo V.Viveiros; Bergallo, H. G.In the middle of a political and fiscal crisis, the Brazilian government is applying successive budget cuts, including in science funding. Recent cuts radically affect research programs on biodiversity that are crucial components for the design and monitoring of public policies for nature conservation and sustainable development. We analyze the consequences of such cuts on the Research Program on Biodiversity (...
Biased-corrected richness estimates for the Amazonian tree flora
ter Steege, H.; Prado, Paulo I.; Lima, Renato A.Fde; Pos, Edwin T.; Coelho, Luiz Souza de; Lima Filho, Diógenes de Andrade; Salomão, Rafael PaivaAmazonian forests are extraordinarily diverse, but the estimated species richness is very much debated. Here, we apply an ensemble of parametric estimators and a novel technique that includes conspecific spatial aggregation to an extended database of forest plots with up-to-date taxonomy. We show that the species abundance distribution of Amazonia is best approximated by a logseries with aggregated individuals,...

Litterfall production in intact and selectively logged forests in southern of A...
Almeida, Everton José; Luizão, Flávio Jesus; Rodrigues, Domingos de JesusA capacidade de reaproveitamento de nutrientes pela floresta está ligada à produção e decomposição da serrapilheira, sendo estes processos essenciais para manutenção da floresta, especialmente em regiões de solos nutricionalmente pobres. Intervenções humanas na floresta como a extração seletiva de madeira, podem ter fortes impactos sobre esses processos. Os objetivos deste trabalho foram estimar a produção de s...

Predation on amphibians by spiders (Arachnida, Araneae) in the Neotropical region
Menin, Marcelo; Rodrigues, Domingos de Jesus; Azevedo, Clarissa Salette deHerein, we report observations about spider predation on anurans (adults and juveniles) in Central Amazonia and a literature review of spiders preying on amphibians in the Neotropical zoogeographic realm. We conducted field observations in Reserva Florestal Adolpho Ducke, Manaus, AM, and observed eight predation events on Bufonidae, Dendrobatidae, Hylidae, and Leptodactylidae frogs. The predators belong to the ...
