This report was written to provide background information for aquatic ecologists interested in
using stable isotope analysis (SIA). Ratios of stable isotopes of carbon (13C/12C), nitrogen …

Diel vertical migration (DVM) is common in aquatic organisms. The trade‐off between
reduced predation risk in deeper, darker waters during the day and increased foraging …

Lake Ontario supports a diversity of native and non-native salmonids which are managed
largely through stocking practices. Ecological changes (eg, invasive species) altering the …

Per-and polyfluoroalkyl substances (PFAS) are globally distributed in the natural
environment, and their persistent and bioaccumulative potential illicit public concern. The …

We quantified piscivory patterns in the main basin of Lake Huron during 1984–2010 and
found that the biomass transfer from prey fish to piscivores remained consistently high …

Oligotrophic lakes are generally dominated by calanoid copepods because of their
competitive advantage over cladocerans at low prey densities. Planktivory also can alter …

The stable carbon isotope ratio δ13C is a useful tracer of energy flow in lake food webs, and
the zooplankton signature is commonly used to establish a baseline for the pelagic habitat …

The benthic amphipod Diporeia spp. is an important prey for many fish in offshore areas of
the Great Lakes, but its abundance has been rapidly decreasing. To assess the influence of …

Per-and polyfluoroalkyl substances (PFAS) are a group of synthetic chemicals detected
throughout the environment. To better understand the distribution of PFAS in an aquatic …

The magnitude of the spring bloom in the open waters of Lake Huron has declined
dramatically in recent years, beginning in 2003. May chlorophyll values, as estimated by …
