You can’t go home again. While the sentiment means something a bit more figurative to those of us who traveled for the Holidays, for Great Lakes fishes the statement is all too literal. In fact, there are more than 275,000 reasons a fish might not make it “home.” This amazing animation is from our new …
Solomon David spoke at the CFL last week about the November migrations of the Great Lakes populations of whitefish. We started thinking about ways to spread the message that keeping fish “on the move” is crucial to their survival. Here’s an animated attempt: Let us know what you think in the comments. This was a …
Welcome to our new “Field Samples” series. We conduct so much cool research at the CFL, that it’s hard to keep track. So, each week, we’ll do a Q&A with a faculty member, post doc, or grad student and ask what they’ve been up to, where it’s taken them, and what they’ve learned. Today, Aaron …
Last week, an excellent article in the Milwaukee Journal Sentinel covered some great news – lake whitefish are migrating inland to spawn and, in many cases, fish were running up into tributaries where they hadn’t been seen for 100 years. One of the scientists featured in that article is Solomon David, a post doctoral researcher …
The CFL’s Ellen Hamann, lab manager for Pete McIntyre’s lab, has been back in Africa this summer, helping continue research on Lake Tanganyika. She sent in this note from the field before returning to Madison for fall semester. By Ellen Hamann For the past 48 hours, Benja (Ben Kraemer from Pete McIntyre’s lab) and I …
Over the last several years, state agencies and environmental non-profit organizations have targeted dam removal as a way to quickly improve the health of aquatic ecosystems. Dams keep migratory fish from swimming upriver to spawn, block nutrients from flowing downstream, and change the entire hydrology of a watershed. From an ecosystem perspective, taking down a …
While a lot of what we do at the Center for Limnology is all about Wisconsin waters, we’ve got some world-class research going on all over the world, from places like Tanzania and Thailland. Aaron Koning, a grad student in Pete McIntyre’s lab, is working on understanding the fish communities in both the Chao Phraya …
Last spring, we featured UW grad student, Dan Oele’s work on northern pike in Green Bay. Dan was trying to answer the question, “Do pike return to the waters where they first emerged from eggs to spawn, or will any suitable stream do?” Now, it appears he has an answer. And his results are good …
Not everyone at the CFL is braving subzero temperatures this winter. Faculty member, Pete McIntyre, is currently working in balmier weather, conducting fieldwork with grad student, Aaron Koning in Thailand, They are looking at fish migrations in the Mekong River and its tributaries. The Mekong, which flows through parts of China, Myanmar, Laos, Thailand, Cambodia …
Field season is, of course, where the best photo ops and a lot of the fun of being a research scientist happens. If you’re a loyal reader of this blog, you’ll remember a handful of lively dispatches from the CFL’s Ellen Hamann as she worked this summer with the McIntyre lab on the Tanzania shoreline …
