Freshwater fish are in a perilous state with more than 30% of species considered critically
endangered. Yet significant ecological and methodological complexities constrain our ability …

We investigated modern-littoral and subfossil sediment-core diatoms in the shallow (max
depth 6.4 m) high-mountain Lake Balma in the Orsiera Rocciavrè Nature Park (Italian …

High-mountain lakes are pristine ecosystems characterized by extreme environmental
conditions. The atmospheric transport of pollutants from lowlands may add further stress to …

Alpine lakes are well known as “environmental sentinels”, which are sensitive to
anthropogenic impacts, and paleoecological studies provide useful information regarding …

Introduction of exotic species is one of the major human impacts for decline in
autochthonous biodiversity. In freshwater lentic environments, alien fish introduction heavily …

While the significance of anthropogenic pressures in shaping species distributions and
abundances is undeniable, some ambiguity still remains on their relative magnitude and …

We demonstrate how mechanistic modeling can be used to predict whether and how
biological responses to chemicals at (sub) organismal levels in model species (ie, what we …

Little is known about the effect of top predator introduction in historically fishless
communities, especially on remote islands. This issue is important because it might strongly …

High-altitude lakes have been studied intensively over the last decades both in terms of their
biota and general physicochemical patterns and the importance of detailed knowledge of …

Given the current rate of Arctic warming, the associated ecological changes need to be put
into a longer-term context of natural variability. Palaeolimnology offers tools to explore …
