Seasonal variation of plant communities and their environments along a topographic gradient in the Iberá wetland, ancient Paraná fl oodplain, Argentina
(Gebruder Borntraeger, 2013-06)
Recently, wetlands have declined worldwide due mainly to habitat loss by human activities. In order to achieve a better understanding of the impacts that are being generated on the Iberá wetland in northeastern Argentina, ...
Linking landscape heterogeneity with lake dissolved organic matter properties assessed through absorbance and fluorescence spectroscopy: Spatial and seasonal patterns in temperate lakes of Southern Andes (Patagonia, Argentina)
(Elsevier, 2019-10-10)
Hydrological connectivity between terrestrial and aquatic systems is influenced by landscape features. Topography, vegetation cover and type, lake morphometry and climate (seasonality, precipitation) drive the timing, ...
Environmental Quality and Aquatic Invertebrate Metrics Relationships at Patagonian Wetlands Subjected to Livestock Grazing Pressures
(Public Library of Science, 2015-10)
Livestock grazing can compromise the biotic integrity and health of wetlands, especially in remotes areas like Patagonia, which provide habitat for several endemic terrestrial and aquatic species. Understanding the effects ...
Identifying high priority conservation areas for Patagonian wetlands biodiversity
(Springer, 2021-03)
Given the multiple stressors affecting freshwater ecosystems and the limited resources devoted to their management, effective conservation of freshwater biodiversity requires regional prioritization. Patagonian wetlands ...
Effects of hydrogeochemistry on the microbial ecology of terrestrial hot springs
(2023)
Temperature, pH, and hydrochemistry of terrestrial hot springs play a critical role in shaping thermal microbial communities. However, the interactions of biotic and abiotic factors at this terrestrial-aquatic interface ...
Phylogeny, Ecology, and Heart Position in Snakes
(Univ Chicago Press, 2010-01-01)
The cardiovascular system of all animals is affected by gravitational pressure gradients, the intensity of which varies according to organismic features, behavior, and habitat occupied. A previous nonphylogenetic analysis ...

Which environmental variables better explain changes in anuran community composition? A case study in the restinga of Mata de São João, Bahia, Brazil
(2007)
Most studies of amphibian communities are restricted to aquatic environments, which precludes sound descriptions of changes in composition throughout entire habitats. Moreover, few works focus on the environmental processes ...
Physical controls on carbon dioxide transfer velocity and flux in low-gradient river systems and implications for regional carbon budgets
(AMER GEOPHYSICAL UNION, 2011)
Outgassing of carbon dioxide (CO(2)) from rivers and streams to the atmosphere is a major loss term in the coupled terrestrial-aquatic carbon cycle of major low-gradient river systems (the term ""river system"" encompasses ...
