Lakes are complex ecosystems composed of distinct habitats coupled by biological, physical
and chemical processes. While the ecological and evolutionary characteristics of aquatic …

Population and community descriptors that might be used as indicators of the impact of
fishing are reviewed. The criteria used for the evaluation of these indicators are meaning …

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 …

Use of stable isotope ratios to trace pathways of organic matter among consumers requires
knowledge of the isotopic shift between diet and consumer. Variation in trophic shift among …

Stable isotope ratios (typically of carbon and nitrogen) provide one representation of an
organism's trophic niche and are widely used to examine aspects of food web structure. Yet …

Stable isotopes are a powerful tool for ecologists, often used to assess contributions of
different sources to a mixture (eg prey to a consumer). Mixing models use stable isotope …

Stable nitrogen isotope signatures (δ 15 N) are increasingly used to infer the trophic position
of consumers in food web studies. Interpreting the δ 15 N of consumers relative to the δ 15 N …

1. Stable isotopes of nitrogen and carbon are widely used in the evaluation and
understanding of trophic interactions, and especially so in aquatic food‐webs. However …

Studies of lake ecosystems generally focus on pelagic food chains and processes. Recently,
there has been an emerging recognition of the importance of benthic production and …

Articles ductivity and heterotrophic bacterial productivity rather than biomass because we
were interested in energy flow in lake food webs. However, we found measurements of …
