The role of climate on floristic composition in a latitudinal gradient in the Brazilian atlantic forest
(2018-11-01)
Background and aims – Latitudinal gradients have an important influence on species distribution reflecting the effects of environmental factors such as temperature, rainfall, soil, and geographical distance. In the ...
Causas da distribuição de aves da Amazônia: uma questão da escala taxonômica
(Universidade Federal de Santa MariaBrasilCiências BiológicasUFSMPrograma de Pós-Graduação em Biodiversidade AnimalCentro de Ciências Naturais e Exatas, 2020-02-27)
One of the main questions in biogeography is the role of cladogenesis across barriers vs. ecological specialization on species distribution. In Amazonia, rivers have long been hypothesized to limit species dispersal and ...
Secondary invasions hinder the recovery of native communities after the removal of nonnative pines along a precipitation gradient in Patagonia
(MDPI AG, 2018-07-04)
The removal of nonnative species can lead to re-invasion by nonnative species, especially in communities with multiple co-occurring invaders. Biotic and abiotic conditions shape community structure, reducing the predictability ...
Patterns of interaction between plants and pollinators along an environmental gradient
(Wiley Blackwell Publishing, Inc, 2005-06)
Patterns of variation in plant-pollinator (p-p) systems in response to environmental variables have been the focus of much recent attention. We analyzed species diversity and generalization of interactions of flower visitors ...
Effects of preweaning polysensorial enrichment upon development of the parietal cortical plate of undernourished rats: a stereological study
(Universidad de la Frontera, 2014)
This investigation was undertaken in order to quantify the effects of early polysensorial enrichment on the
development of cortical pyramids, located in the parietal cortex of rats simultaneously submitted to protein-energy ...

Interactions, environmental sorting and chance: phylostructure of a tropical forest assembly
(Folia Geobotanica, 2019)
Ant species distribution along a topographic gradient in a "terra-firme" forest reserve in Central Amazonia.
(Pesquisa Agropecuária Brasileira, v. 44, n. 8, p. 852-860, ago. 2009., 2014)
Stress-gradient hypothesis and plant distribution along ecotonal gradients
(Wiley Blackwell Publishing, Inc, 2018-11)
The stress-gradient hypothesis (SGH) predicts that, although facilitation and competition occur together, facilitative interactions will be more prevalent with increasing abiotic stress. In water-limited ecosystems, support ...
