“We’ve spent years convincing the public of the need to maintain connectivity in aquatic systems. Now the challenge is to explain why there are exceptions to that paradigm.” – F. Rahel This quote reflects...
Our oceans are becoming warmer and more acidic due to anthropogenic CO2 and marine ectotherms, or animals dependent on external sources of body heat, must adjust to these new environmental conditions. Many scientists are looking at...
Changes in land use and local habitat conditions threaten aquatic life in streams and rivers, but this occurs against the backdrop of climate change. To overcome local and watershed degradation, conservation groups are attempting...
Cass Lake is a beautiful 16,000 acre lake in northern Minnesota known for its abundant and large Walleye (Sander vitreus). The Upper Mississippi River flows from Cass Lake into Lake Winnibigoshish, and was historically...
You’ve probably heard of invasive species. You may even be able to name a few and describe how they impact ecosystems. Invasive species are non-native species that have undesirable effects on the ecosystems they...
The Los Angeles River Revitalization Master Plan is an ambitious project, seeking to balance flood protection with ecological, economic, and community development interests along 32 river miles. Passing between the Los Angeles National Forest...
Overfishing threatens many fisheries world-wide. Conservation strategies and regulations put in place to protect fisheries rely heavily upon estimates of the abundance and distribution of fish. Fisheries managers have traditionally used seine nets, fyke...
The Yucatán Peninsula is home to a unique group of underwater habitats that look like circular swimming pools. These beautiful formations are known as cenotes, meaning “natural well” in Spanish. Formed through the gradual...
Dams are concrete roadblocks along an aquatic road; a perceptible challenge to habitat connectivity. Impounding rivers creates reservoirs, turning a natural river system into a lake. This can affect water temperature and flow regimes,...
Rivers are an important part of our way of life. They provide hydropower, drinking water, fishing, irrigation, recreational activities, and transportation, among other benefits. Rivers are often altered to enhance their ability to perform...
