After two years of focusing my aquatic ecology class almost entirely on lakes, I’m excited to expand into stream ecology this year. We will compare and contrast depth gradients in lakes with elevation gradients in a nearby stream which climbs from 312 m to 659 m, all within just 3 km of campus.

In aquatic ecology, what is “spring”? A calendar date, a daylength threshold, or the moment lake ice melts? Led by @aslewis.bsky.social , we show how seasonal definitions fundamentally shape our understanding of climate change impacts on waterbodies. dx.doi.org/10.1002/lol2...

Map of global lake distribution, colored by the number of SWOT overpasses per 21 day cycle. There are many lakes with a high number of SWOT overpasses at high northern latitudes, but there are also tens of thousands to more than a million lakes on every continent. Lakes are graphed by latitude and longitude on the edges of the figure.

Contrary to the assumption that floodwaters washed contamination away, Dr. Oleksandra Shumilova et al reveals the opposite: toxic pollutants trapped in sediments were unleashed, turning the former reservoir into a contamination hotspot. Future floods could spread these pollutants even further.
