Effects of dredging on benthic diatom assemblages in a lowland stream
(Elsevier, 2009-12)
The objective of this study was to assess the effects of dredging on the structure and composition of diatom assemblages from a lowland stream and to investigate whether the response of diatom assemblages to the dredging ...
Habitat type and macroinvertebrate assemblages in low order Patagonian streams
(E. Schweizerbart´sche Verlagsbuchhandlung, 2003-12)
Benthic macroinvertebrate community structure was studied with respect to stream habitat type in four low-order Patagonian streams (Argentina). Seven habitat types were sampled during high and low water periods in each ...
Macrobenthic Assemblages of Intertidal Flats in Southern Patagonia, Argentina
(Universidade de Vigo, 2019-10-05)
The aim of this work was to characterize the macrobenthic community of intertidal flats in southern Patagonia, by identifying the faunal assemblages and analyzing their relationship with the main environmental factors. The ...
Simulated overfishing and natural eutrophication promote the relative success of a non-indigenous ascidian in coral reefs at the Pacific coast of Costa Rica
(2017)
Colonial ascidians of the genus Didemnum are common fouling organisms and are typically associated with degraded ecosystems
and anthropogenic structures installed in the sea. In this study, however, the non-indigenous ...
Suspension feeders as natural sentinels of the spatial variability in food sources in an Antarctic fjord: A stable isotope approach
(Elsevier Science, 2020-08)
We examined the effect of glacial melt-related retreat environmental conditions on the spatial heterogeneity of food sources for Antarctic nearshore marine benthic communities of Potter Cove, a representative fjord on King ...
Engineering by an invasive species alters landscape-level ecosystem function, but does not affect biodiversity in freshwater systems
(Wiley, 2014-02)
Aim: Ecological theory predicts that invasive ecosystem engineers like the American beaver (Castor canadensis) in Tierra del Fuego (TDF) affect landscape-level biodiversity and ecosystem function (BEF) when engineered ...
A estrutura da comunidade de macro-invertebrados bentônicos em três represas do médio rio Tietê (SP), com ênfase nas espécies exóticas Melanoides tuberculata (Gastropoda, Thiaridae) e Corbicula fluminea (Bivalvia, Corbiculidae)
(Universidade Federal de São CarlosBRUFSCarPrograma de Pós-Graduação em Ecologia e Recursos Naturais - PPGERN, 2006-02-24)
The reservoirs are artificial ecosystems constructed by the man and attend to the multiple
uses. The reservoir provokes alterations in the aquatic ecosystem, causing modifications in
the chemical and physical composition ...
Climate change and alpine stream biology: progress, challenges, and opportunities for the future
(BLACKWELL PUBLISHING LTD, 2017-11-01)
In alpine regions worldwide, climate change is dramatically altering ecosystems and affecting biodiversity in many ways. For streams, receding alpine glaciers and snowfields, paired with altered precipitation regimes, are ...
Bioaccumulation of potentially toxic trace elements in benthic organisms of Admiralty Bay (King George Island, Antarctica)
(Londres, 2013)
Data about the concentration, accumulation and transfer of potentially toxic elements in Antarctic marine food webs are essential for understanding the impacts of these elements, and for monitoring the pollution contribution ...
