Your Drop Matters
-
Just forty-five years ago, rivers in the U.S. were so polluted that some actually burned. In response, our country created the Clean Water Act amid other strong environmental legislation. Today, two-thirds of our population has never known a time when clean water wasn’t readily available. Despite improvements in the quality of drinking water, freshwater animals and habitats in the southeastern U.S. remain among the most imperiled on Earth. We have become complacent with institutional protections and haven’t challenged our personal behaviors. How can we solve the freshwater crisis starting in our own backyard? Video by TEDxChattanooga.

Drought Prompts Endangered Fish Rescue
-
The Tennessee Aquarium and U.S. Fish & Wildlife Service launched a fish rescue on November 22. The historic drought conditions had reduced the number of locations where the federally endangered Laurel Dace are found. Most of the streams where these brightly colored fish are found have dried up, leaving only a few shallow pools. Only 18 Laurel Dace were recovered and brought back to the Tennessee Aquarium Conservation Institute for an "ark population," in case this species disappears in the wild. Hopefully these 18 fish will reproduce in the spring allowing scientists an opportunity to bolster the diminishing populations of Laurel Dace in Tennessee.

Tennessee Aquarium Conservation Institute - Freshwater Biodiversity
-
The warm waters of the southeastern United States are home to an amazing diversity of animals and habitats. The Tennessee Aquarium Conservation Institute (TNACI) works to protect and sustain the region's natural treasures and bring people of all ages closer to nature. Help us celebrate and care for these riches in our backyards.

Mapping our Rivers in High Definition
-
A project video produced by Tennessee Wildlife Resources Agency (TWRA) for Trutta Consulting LLC High Definition Stream Survey (HDSS) of the Caney Fork River below Center Hill Dam. The project was supported by the Cumberland Chapter of Trout Unlimited, Tennessee Department of Environment and Conservation and TWRA. We also worked with TWRA fisheries sampling crew to video and GPS their trout surveys that were completed at the same time as the HDSS project. This allows us to see the conditions that the fish were captured and determine what areas of the river are best for trout at different flow conditions.

Endangered Mussels Released into the Clinch River, Largest Release in Eastern US
-
Biologists from the Virginia Department of Game and Inland Fisheries (VDGIF), and partners from Virginia Tech, the Nature Conservancy, and the U.S. Fish and Wildlife Service stocked thousands of mussels into the Clinch River, Russell County. The Clinch River has more species of endangered freshwater mussels than any other river in North America. Elementary school students from Cleveland, VA, participated in the event, and learned about the many functions of mussels, including providing habitat for fish, becoming food for many other animals, and filtering and cleaning the water in our streams and rivers. Over 3,500 federally-endangered mussels were produced at the Department's Aquatic Wildlife Conservation Center in Marion, Virginia.

A Chinese cave links climate change, social impacts, and human adaptation over the last 500 years
-
The collapse of some pre-historical and historical cultures, including Chinese dynasties were presumably linked to widespread droughts, on the basis of synchronicities of societal crises and proxy-based climate events. Here, we present a comparison of ancient inscriptions in Dayu Cave from Qinling Mountains, central China, which described accurate times and detailed impacts of seven drought events during the period of 1520–1920 CE, with high-resolution speleothem records from the same cave. The comparable results provide unique and robust tests on relationships among speleothem δ18O changes, drought events, and societal unrest. With direct historical evidences, our results suggest that droughts and even modest events interrupting otherwise wet intervals can cause serious social crises. Modeling results of speleothem δ18O series suggest that future precipitation in central China may be below the average of the past 500 years. As Qinling Mountain is the main recharge area of two large water transfer projects and habitats of many endangered species, it is imperative to explore an adaptive strategy for the decline in precipitation and/or drought events.
