Long‐Term and Regional‐Scale Data Reveal Divergent Trends of Different Climate Variables on Fish Body Size Over 75 Years
This research demonstrated that over the past 75 years many ages of multiple species of freshwater fishes were decreasing in length through time and with increasing water temperatures. The largest de...

1/ New research from our group @umich.edu in collaboration with MI DNR investigated if climate change is altering fish body size. Our team analyzed data from 13 species and 1,497 lakes from 1945-2020.

New in @biolinvasions.bsky.social: I argue that accelerating invasion rates threaten ecosystem stability & sustainable management. Thus there is an urgent need for progress toward Target 6 of the Kunming-Montreal GBF, which calls for a substantive reduction in global invasion rates.

Invasions are as costly as natural disasters:
From 1980 to 2019, financial losses attributed to invasive species amounted to $1.2 trillion (USD), compared to $1.9 trillion in losses caused by storms, $1.14 trillion caused by earthquakes, and $1.12 trillion due to floods. phys.org/news/2023-04...
