Determining diet is a key prerequisite for understanding species interactions, food web
structure and ecological dynamics. In recent years, there has been considerable …

The ice‐cover period in lakes is increasingly recognized for its distinct combination of
physical and biological phenomena and ecological relevance. Knowledge gaps exist where …

Stable isotope analysis provides a powerful tool to identify the energy sources which fuel
consumers, to understand trophic interactions and to infer consumer trophic position (TP), an …

Temporal variation characterizes many of Earth's ecosystems. Despite this, little is known
about how food webs respond to regular variation in time, such as occurs broadly with …

Global climate change has led to profound alterations of the Arctic environment and
ecosystems, with potential secondary effects on mercury (Hg) within Arctic biota. This review …

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 …

Littoral benthic primary production is considered the most important energy source of
consumers in subarctic lakes. We analyzed essential fatty acid (EFA) and amino acid (EAA) …

Prey preference of top predators and energy flow across habitat boundaries are of
fundamental importance for structure and function of aquatic and terrestrial ecosystems, as …

Trophic transfer and retention of dietary compounds are vital for somatic development,
reproduction, and survival of aquatic consumers. In this field study, stable carbon and …

Ice phenology has shifted with anthropogenic warming such that many lakes are
experiencing a shorter ice season. However, changes to ice quality—the ratio of black and …
