Glacial melting: An overlooked threat to Antarctic krill
(Nature Publishing Group, 2016-06)
Strandings of marine animals are relatively common in marine systems. However, the underlying mechanisms are poorly understood. We observed mass strandings of krill in Antarctica that appeared to be linked to the presence ...
Secondary Lahars Triggered by Periglacial Melting at Chimborazo Volcano, Ecuador
(Escuela Politécnica Nacional, 2021)
Glacial melt disturbance shifts community metabolism of an Antarctic seafloor ecosystem from net autotrophy to heterotrophy
(Nature, 2021-01)
Climate change-induced glacial melt affects benthic ecosystems along the West Antarctic Peninsula, but current understanding of the effects on benthic primary production and respiration is limited. Here we demonstrate with ...
Can increased glacial melting resulting from global change provide attached algae with transient protection against high irradiance?
(Wiley Blackwell Publishing, Inc, 2014)
Seasonal variability in glacial influence affects macroinvertebrate assemblages in North-Andean Patagonian glacier-fed streams
(Taylor & Francis Ltd, 2019-10)
Macroinvertebrate communities of glacial streams are affected by melting mountain glaciers, which in turn are influenced by landscape and local and global climate change. We analyzed macroinvertebrate communities in 2 ...
Glacial Discharge and its Impact on Phytoplankton Taxonomic Composition in an Antarctic Fjord
(American Geophysical Union, 2020)
The influence of glacial discharge on phytoplankton community composition remains an open question. The Antarctic Peninsula fjords offer an ideal system to understand the effect of ice-ocean forcing on phytoplankton ...
Glacier melting and stoichiometric implications for lake community structure: zooplankton species distributions across a natural light gradient
(Wiley, 2013-02)
Glaciers around the globe are melting rapidly, threatening the receiving environments of the world´s fresh water reservoirs with significant changes. The meltwater, carried by rivers, contains large amounts of suspended ...
Melting of clean and debris-rich ice differentially affect nutrients, dissolved organic matter and bacteria respiration in the early ontogeny of the newly formed proglacial Ventisquero Negro Lake (Patagonia Argentina)
(Wiley Blackwell Publishing, Inc, 2018-11)
Climate change affects glaciers all over the world causing glacial recession with the formation of new lakes. Glaciers of Mount Tronador (41° S, Patagonia, Argentina) underwent an increase of more than 200 m in the ...
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 ...
Fossil diversity and taphonomy of glacial and post-glacial lower paleozoic strata, NE Paraná Basin, Brazil
(2021-11-01)
Unlike other South American basins, the boundary between Ordovician and Silurian in the Paraná Basin, Brazil, has yet to be studied in detail. This article reports the occurrence and taphonomic analysis of a fauna composed ...
