Abstract Warming can have profound impacts on ecological communities. However, explorations of how differences in biogeography and productivity might reshape the effect of warming have been limited to theoretical or proxy-based approaches: for instan

Publikováno v: Limnology and Oceanography Letters, Vol 7, Iss 4, Pp 332-341 (2022)
Abstract Climate warming and eutrophication are leading drivers of environmental change, and both are likely to alter the role of freshwaters in the global carbon cycle. Recent studies demonstrate that warming of streams can increase freshwater contr

Publikováno v: PLoS ONE, Vol 17, Iss 5, p e0264501 (2022)
In many respects, freshwater springs can be considered as unique ecosystems on the fringe of aquatic habitats. This integrates their uniqueness in terms of stability of environmental metrics. The main objective of our study was to evaluate how enviro

Invertebrate biodiversity in cold groundwater fissures in Iceland
Autor: Jónína H. Ólafsdóttir, Jóhann G. Þorbjörnsson, Bjarni K. Kristjánsson, Jón S. Ólafsson
Publikováno v: Ecology and Evolution, Vol 9, Iss 11, Pp 6399-6409 (2019)
Abstract Iceland has an abundance of fissures that are parallel to the Mid‐Atlantic Ridge where bedrock cracks as a result of continental rifting. Some fissures penetrate the aquifer and expose the groundwater within the bedrock, becoming springs.

Publikováno v: Scientific Reports, Vol 7, Iss 1, Pp 1-12 (2017)
Abstract The underlying mechanism driving the structural amorphous-to-crystalline transition in Group VI chalcogenides is still a matter of debate even in the simplest GeTe system. We exploit the extreme sensitivity of 57Fe emission Mössbauer spectr

Chironomidae fauna of springs in Iceland: Assessing the ecological relevance behind Tuxen’s spring classification
Autor: Agnes-Katharina Kreiling, Jón S. Ólafsson, Snæbjörn Pálsson, Bjarni K. Kristjánsson
Publikováno v: Journal of Limnology (2018)
In 1937, S.L. Tuxen studied the animal community of hot springs in Iceland, and classified springs according to their relative temperature into cold, tepid, and hot. Eighty years after Tuxen’s study, we revisited some of the hot springs in Skagafj
