Stable carbon and nitrogen isotope analyses of human and animal tissues have become an
important means of studying both anthropogenic and natural food webs in aquatic …

ABSTRACT 1 Stable isotope analysis (SIA) has the potential to become a widespread tool in
mammalian ecology, because of its power in resolving the ecological and behavioural …

Nitrate (NO3−) concentrations in public water supplies have risen above acceptable levels
in many areas of the world, largely as a result of overuse of fertilizers and contamination by …

The recent expansion of natural abundance stable isotope methods has rapidly increased
our understanding of freshwater food web ecology. Investigators now routinely use stable …

Trophic dynamics (community composition and feeding relationships) have been identified
as important drivers of methylmercury (MeHg) bioaccumulation in lakes, reservoirs, and …

Intraspecific and interspecific variation in the trophic position of various consumers is central
to many theories of aquatic ecosystem functioning and dynamics. In recent years, such …

Parallel phenotypic evolution in similar environments has been well studied in evolutionary
biology; however, comparatively little is known about the influence of determinism and …

Rivers in urban locations frequently receive contaminated wastewater and particulate waste
either directly from storm overflows or from sewage treatment facilities. Although many urban …

Broad‐scale assessment of stream health is often based on correlative relationships
between catchment land‐use categories and measurements of stream biota or water …

The nitrogen stable isotope ratio of biological tissue has been proposed as an indicator of
anthropogenic N inputs to aquatic ecosystems, but overlap in the isotopic signatures of …
