Drivers of phytoplankton diversity in patagonian and antarctic lakes across a latitudinal gradient (2150 km): The importance of spatial and environmental factors
(Springer, 2015-04)
We investigated the phytoplankton structure in 60 lakes across a latitudinal gradient (2150 km), from Austral Patagonia to Antarctica, including environments ranging from oligotrophic to eutrophic. We analysed the latitudinal ...
Padrões de diferenciação florística no extremo sul da Mata Atlântica: influências ambientais e histórica
(Universidade do Vale do Rio dos Sinos, 2011-02-18)
The spatial variation of species abundance can be determined by a series of historical and environmental causes. In order to identify floristic groups and their relationship to a set of soil and climatic variables ...

Contribution of environmental variables to anuran community structure in the Caatinga Domain of Brazil
(Brasil, 2011)
To ascertain the influence of environmental variables on the structure of anuran communities, we conducted tests to determine which variables best explain the spatial distribution patterns of different communities of anurans ...
NADPH-d positive neurons in the developing somatosensory cortex of the rat: effects of early and late environmental enrichment
(ELSEVIER SCIENCE BV, 1998)
The effects of environmental enrichment upon the topographic arrangement of NADPH diaphorase-positive neurons (NADPH-d(+) neurons) was studied in the somatosensory cortex of 56 Sprague-Dawley albino rats during early stages ...
Spider (Arachnida-Araneae) diversity in an Amazonian altitudinal gradient: Are the patterns congruent with mid-domain and rapoport effect predictions?Diversidade de aranhas (Arachnida-Araneae) em um gradiente altitudinal na amazônia. seriam os padrões congruentes com o esperado pelo efeito do dominio central e pelo efeito rapoport?
(2021-01-01)
The Mid-Domain Effect (MDE) and the Rapoport (RE) effect are two biogeographical theories that make predictions about biogeogaphic patterns. MDE predicts higher richness in the central portions of a gradient if it is within ...
Podem pequenas variações na altitude e na ordem de riachos influenciar a estrutura das comunidades de moluscos?
(Universidade Federal de Santa MariaBRCiências BiológicasUFSMPrograma de Pós-Graduação em Biodiversidade Animal, 2012-05-31)
The influence of small gradients of altitude (0-500 meters) and order (1st to 4th) in the
spatial distribution of mollusk communities was studied, based on 40 samples collected in a
watershed of a temperate climate region, ...
Caracterização da diversidade filogenética e o legado de paisagens em comunidades de peixes de riacho
(Universidade Federal de São CarlosUFSCarCâmpus São CarlosBiotecnologia - Biotec, 2023-03-24)
Freshwater fish constitute the most diverse group of continental vertebrates recorded, in which the aquatic ecosystems they inhabit are in constant and complex connection with the vegetative area around them. Furthermore, ...
