Determining how environmental conditions contribute to divergence among populations and
drive speciation is fundamental to resolving mechanisms and understanding outcomes in …

Climate change in the Arctic is outpacing the global average and land‐use is intensifying
due to exploitation of previously inaccessible or unprofitable natural resources. A …

Subarctic lakes are getting warmer and more productive due to the joint effects of climate
change and intensive land-use practices (eg forest clear-cutting and peatland ditching) …

Cold‐water lakes situated in high latitudes and altitudes have pivotal socio‐ecological
importance both globally and locally. However, they are increasingly threatened by multiple …

Mountain lakes are the most affected by climate change; however, few of these lakes are
regularly sampled because of their remoteness. We discussed limnological data (eg water …

The size of a lake ecosystem sets many direct and indirect physical limits for habitats
available for different food web compartments as well as the taxa inhabiting these. We tested …

It is considered that allopatric speciation proceeds slower than sympatric speciation and
rarely results in rapid differentiation of populations. In particular, high intraspecific …

Fish growth in river ecosystems is influenced by a multitude of environmental drivers,
including the heterogeneity of these drivers. Globally, river ecosystems are subject to …

The structure and functioning of Arctic ecosystems have been drastically modified by global
warming, with fish species potentially performing habitat shifts such as the northern …

Mercury is a toxic metal that enters to aquatic consumers through diet and bioaccumulates
with increasing size and age. Mercury content, growth and their derivate mercury growth …
