Shifts in diversity and function of lake bacterial communities upon glacier retreat
Global climate change is causing a wastage of glaciers and threatening biodiversity in glacier-fed ecosystems. The high turbidity typically found in those ecosystems, which is caused by inorganicExpand

Sunlight modulates the relative importance of heterotrophic bacteria and picophytoplankton in DMSP-sulphur uptake
There is a large body of evidence supporting a major role of heterotrophic bacteria in dimethylsulphoniopropionate (DMSP) utilisation as a source of reduced sulphur. However, a role for phototrophicExpand

Larval UV exposure impairs adult immune function through a trade-off with larval investment in cuticular melanin
Summary Despite the strong impact of ultraviolet (UV) radiation on invertebrates, it is unknown whether it affects immune function across metamorphosis. More generally, the mechanisms on how larvalExpand

Presence of large virus-like particles in a eutrophic reservoir
The presence of large virus-like particles (LVLP) studies on morphological diversity of viruses in freshwithout tails was observed in the water of a severely eutrowater and marine environments, onlyExpand

Temporal changes in the dominance of major planktonic bacterial groups in an alpine lake: discrepancy with their contribution to bacterial production
We tested the idea that temporal changes in the numerical dominance of major bacter- ial groups are not necessarily coupled to those in bacterial production. The seasonal dynamics of the bacterialExpand

Differential tolerance of UV radiation between Chaoborus species and role of photoprotective compounds
Previous studies with larvae of the American species Chaoborus punctipennis suggest that this genus is highly sensitive to solar ultraviolet radiation (UVR). Here, we first tested the UV sensitivityExpand

Abstract Glacier retreat as a consequence of climate change influences freshwater ecosystems in manifold ways, yet the physical and chemical bases of these effects are poorly studied. Here, weExpand

Changes in bacterioplankton community structure during early lake ontogeny resulting from the retreat of the Greenland Ice Sheet
Retreating glaciers and ice sheets are among the clearest signs of global climate change. One consequence of glacier retreat is the formation of new meltwater-lakes in previously ice-covered terrain.Expand

The genus Cyclops (Copepoda, Cyclopoida) in Europe
Although copepods of the genus Cyclops are among the most common and dominant plankton taxa of lakes in the northern temperate zone, their taxonomy is still unclear. We analysed an extensive array ofExpand

Mountain lakes: Eyes on global environmental change
Abstract Mountain lakes are often situated in protected natural areas, a feature that leads to their role as sentinels of global environmental change. Despite variations in latitude, mountain lakesExpand
