Biotic interactions drive key ecological and evolutionary processes and mediate ecosystem
responses to climate change. The direction, frequency, and intensity of biotic interactions …

We need accurate predictions about how climate change will alter species distributions and
abundances around the world. Most predictions assume simplistic dispersal scenarios and …

Biological communities are shaped by complex interactions between organisms and their
environment as well as interactions with other species. Humans are rapidly changing the …

Temperate lakes may contain both coolwater fish species such as walleye (Sander vitreus)
and warmwater fish species such as largemouth bass (Micropterus salmoides). Recent …

High-latitude aquatic ecosystems are responding to rapid climate warming. A longer ice-free
season with higher water temperatures may accelerate somatic growth in lake ectotherms …

The temperature dependence of predation rates is a key issue for understanding and
predicting the responses of ecosystems to climate change. Using a simple mechanistic …

Warming temperatures resulting from climate change may alter the distribution and
abundance of many freshwater fish species, especially those in northern latitudes. Owing to …

Host–parasite systems at high latitudes are promising model systems for detecting and
predicting the impact of accelerated environmental change. A major challenge is the lack of …

As the Arctic rapidly warms, sub-Arctic species such as the Atlantic salmon (Salmo salar) are
expected to shift their distributions into the Arctic, potentially facilitating interaction with …

Climate change and species invasions represent key threats to global biodiversity. Subarctic
freshwaters are sentinels for understanding both stressors because the effects of climate …
