Sep 13, 2021 · The lake currently cannot support fish, because of oxygen depletion over winter. The installation of an aerator planned for the summer of 2023 is intended to maintain sufficient dissolved oxygen levels over winter, which is needed to support self-sustaining populations of fish.

Jan 29, 2013 · In Trefry Lake, Nova Scotia (Canada), Korosi and Smol (Korosi and Smol, 2012) documented a large decrease in all subfossil Bosmina (mainly E. longispina) size measures (carapace, antennule and mucro lengths), following the elimination of the native fish community by copper sulfate treatment and subsequent restocking with brook trout.

Most studies on zooplankton responses to acidification have focused on clearwater lakes with a dramatic acidification history. The role of dissolved organic carbon (DOC) in moderating zooplankton responses to acidification in naturally acidic, dystrophic lakes is less well understood and is partially impeded by a lack of baseline data. 2.

Sep 28, 2011 · Increased algal blooms are a threat to aquatic ecosystems worldwide, although the combined effects of multiple stressors make it difficult to determine the underlying causes.

Daphnia and Bosmina fragments were identified and measured in the surface sediments of 42 lakes in the Muskoka-Haliburton region of Ontario, Canada, in an attempt to identify environmental factors...

Apr 13, 2016 · As cladocerans are a primary food source for fish, predator avoidance is important to sustain cladoceran populations. We hypothesized that Bosmina longirostris and Daphniaobtusa would show different …

trophic interactions in response to declining calcium (Ca) concentrations, a water quality issue only recently recognized in Europe and North America, can be linked with unexplained bloom production.

Leuciscus cephalus is a transient species that uses these stream mouth habitats only as a temporary 0+ juvenile habitat during fall and early winter. This study suggests that the stream mouth habitats along the river Meuse fulfil different ecological functions for …
