Tribes move whitefish upriver in bid to revive Great Lakes runs Biologists are releasing live whitefish in Upper Peninsula rivers to see whether they can serve as a bridge for large-scale species restoration.

Tribes move whitefish upriver in bid to revive Great Lakes runs

Saving a species but at the expense of others? The way to hell is paved with good intentions. In the hope of saving certain endangered species and ecosystems, some conservation projects propose the introduction of large plant-feeding mammals int...

A study of introductions of large herbivorous mammals outside their native range suggests they do more harm than good to local biodiversity. Only 1 in 5 impacts is positive. Positive effects on certain native species often come at a cost to other natives. #bioinvasions www.unifr.ch/news/en/3344...

Museums had a rough 2025: Report shows lower attendance, lost grants, less money The American Alliance of Museums put out its annual industry snapshot and it's not great. Trump's targeting of museum programming had downstream effects and put a "chill on corporate philanthropy."

Fishes, young and old, are shrinking in Michigan's inland lakes A new study led by the University of Michigan shows that changes in climate are also changing the size of fishes in Michigan's inland lakes.

✨🏠 7/ The take home? When specific climate metrics and fish age are taken into account, clearer patterns emerge for predicting long-term changes. This research can help ecologists, natural resource managers, and policymakers plan for the future.

🌎⚠️ 6/ Why does it matter? Continued body size declines in fishes, especially in the youngest and oldest individuals, could spell trouble for biodiversity and ecosystem functions and services.

🔎📊 5/ These finds show that mixed growth responses to climate change in previous research may be related to age-specific effects and/or the specific climate variable(s) being used. This work suggests that climate change effects on fish body size might be more predictable than previously thought.

❄️ 🥵 4/ For cold- and cool-water adpated fishes, growth responses depended on the climate variable in question. Hotter water temperatures often led to smaller fishes, while longer growing season (increased degree days) usually led to increased growth. Warm-water fishes mostly shrank across the board.

🌡️📈 3) But it's not one-size-fits all. Our modeling demonstrated climate change effects on body size differed by age group and we found divergent trends in response to different aspects of climate change based on thermal guilds.

🌡️📉 2/ Bayesian models revealed that 46% of species age class were changing in length through time with most of those decreasing in length (37% overall shrank through time). Even more, 69%, showed qualitatively smaller lengths.

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.

Oh did we ever. I still remember phones numbers of friends and family that haven't changed, and old numbers for some that have. The only new number I've memorized in the smart phone era is my spouse's because it's on our dog's collar and that's what I see when she's licks my face every morning.
