Environmental and spatial drivers of diatom assemblages in the water column and surface sediment of tropical reservoirs
(Springer, 2019-10-01)
The relative contribution of environmental and spatial drivers of community structure has been the focus of many ecological studies. In the context of metacommunity theory, diatoms have been associated mainly with local ...
Effects of environmental factors on the morphometric characteristics of cultivated lettuce (lactuca sativa l.)
(Universidad Nacional de Colombia, Facultad de Agronomía, Centro Editorial, 2012)
We evaluated the phenotypic response of three varieties of lettuce Batavia Colwart, Lisa Elisa and Crespa Verde Cassabella in three growing environments: plastic greenhouse, glass greenhouse and open field on the Bogota ...
Effect of the landscape context on the density and persistence of a predator population in a protected area subject to environmental variability
(2010)
Protected areas are the most important tool for the conservation of biodiversity. However. many species are area-demanding and their populations seldom meet their space requirements in reserves. In this context, the ...

(Springer, 2016-08)
The aim of this study was to investigate the temporal dynamics (monthly/tidal) of water temperature, salinity, chlorophyll-a (chlo-a), suspended particulate matter (SPM), particulate organic carbon (POC), and dissolved ...
The Strategic Environmental Assessment in Decision Making about Transgenic Crops in Brazil
(Univ Federal Parana, Editora, 2015-04-01)

Effects of biological and environmental factors on the variability of Paralonchurus brasiliensis (Sciaenidae) density: An GAMLSS application
(2022-05-01)
The hypothesis of this study was based on the premise that complex interactions between biological and environmental factors may explain variability in fish population dynamics. To test this, Paralonchurus brasiliensis ...
Metacommunity structuring in stream networks: roles of dispersal mode, distance type, and regional environmental context
(Wiley-Blackwell, 2013-11-01)
Within a metacommunity, both environmental and spatial processes regulate variation in local community structure. The strength of these processes may vary depending on species traits (e.g., dispersal mode) or the characteristics ...
