🐟 WWF’s major new report Africa’s Forgotten Fishes puts the spotlight on the astonishing diversity of Africa’s freshwater fishes

🚨 26% of assessed freshwater fish species on the continent are threatened with extinction, and the true number is likely even higher

The eastern Baltic cod has shrunk dramatically in size in recent decades due to rapid evolution — changes at the genetic level — caused by decades of intensive fishing, a new study says.

It’s one of the first studies to show that a marine species has evolved in response to fishing pressure.

In a synthesis of over 3000 population trends in the Wadden Sea, we show a substantial reorganization of biodiversity with over 38% of populations undergoing significant change (i.e., increases or decreases), identify winners and losers and critical time points of change! dx.doi.org/10.1111/gcb....

💡🍃🌳 Exposure to artificial light at night & higher temperatures extends the growing season of urban plants by up to 3 weeks. This puts additional strain on the energy and water balance of already stressed trees and shrubs. In Europe leaves sprout particularly early. www.igb-berlin.de/en/news/ligh...

Very interesting work! I'm looking forward to the inclusion of juvenile chimps. At Gombe Stream NP, I saw chimps passing a group of baboons when a young chimp started to play with a small baboon. But its mother separated them and pulled it back to the ‘right’ group. Just like some human parents do.
