Leaf litter breakdown and benthic invertebrate colonization affected by seasonal drought in headwater lotic systems of Andean Patagonia
We aimed to establish the effect of seasonal drought on leaf litter breakdown and invertebrate communities. Differences in breakdown rates of Nothofagus pumilio were experimentally compared using the litter bag method ...
Perennial stream discharge in the hyperarid Atacama Desert of northern Chile during the latest Pleistocene
(NATL ACAD SCIENCES, 2007-12-11)
A large fraction of the vital groundwater in the Atacama Desert of northern Chile is likely composed of "fossil" or "ancient" reserves that receive little or no recharge in today's hyperarid climate. Here, we present ...
Does the nature and persistence of a substrate at a mesohabitat scale matter for Chironomidae assemblages? A study in two perennial mountain streams in Patagonia, Argentina
(University Of Arizona, 2012-05)
Chironomid substrate-specific associations regarding the nature (organic-inorganic) and stability (stable-unstable) of different habitats were investigated at two low order Patagonian streams, during high and low water ...
Macroinvertebrados em córregos da região da Mata Atlântica (Sudeste do Brasil) : influência da cultivo de banana
(Universidade Federal de São CarlosBRUFSCarPrograma de Pós-graduação em Ecologia e Recursos Naturais, 2007-08-31)
The integrity of aquatic ecosystems has been compromised by innumerable anthropogenic actions, for example, extensive agriculture that has been producing alterations in water quality and aquatic community characteristics. ...
Gaseous and fluvial carbon export from an Amazon forest watershed
The transfer of carbon (C) from Amazon forests to aquatic ecosystems as CO(2) supersaturated in groundwater that outgases to the atmosphere after it reaches small streams has been postulated to be an important component ...
Influence of land use and climate on the load of suspended solids in catchments of Andean rivers
Understanding the interaction between anthropogenic land use and the rainfall pattern can be crucial to predict changes in total suspended solids (TSS) in streams and rivers. We assessed the effects of land use and ...
Environmental adaptation of the source of the subbasin of Rico Stream, Monte Alto - SP, Brazil
(Associação Brasileira de Engenharia Agrícola (SBEA), 2014)
Groundwater resources of the Western Andean Front: insights from the Aconcagua Basin, Central Chile
(Universidad de Chile, 2020)
The misunderstanding of hydrogeological processes together with the oversimplification of aquifer conceptual models result in numerous inaccuracies in the management of groundwater resources. Despite that Chile is a ...
