Fantastic news from Brazil with deforestation down 41.8% in Amazonia and 23.8% in the Cerrado per INPE figures. The upcoming election could not be more important 🌎 www.gov.br/mma/pt-br/no...
Brasil alcança menores taxas de desmatamento da série histórica na Amazônia e no Cerrado

In an article in Science today @hdavidcooper.bsky.social & @sdiazecology.bsky.social state that to reverse nature loss, we must change what drives it. Protecting 30% of land & sea isn’t enough: we must also transform the economic, political & social forces driving it. @ecioxford.bsky.social
To reverse nature loss, change what drives it
David Cooper and Sandra Díaz publish an editorial in Science calling for the transformation of the root causes of nature loss

"how overfishing combines with the bouts of accelerated oceanic warming driven by El Niño, which always hit Peruvian coastal waters especially hard” www.theguardian.com/news/2026/oc...
A perfect storm: how the super El Niño is devastating the fishing industry
Peru’s anchoveta have made up about a 10th of the entire global commercial fishing catch since 1970, more than any other fish. A combination of warming seas and decades-long overfishing spells disaste...

A new study by researchers in Bern found that certain cypriniform fish species exhibit both small bodies and small genomes, a correlation that has evolved independently in at least three lineages. 🐟🧪
More than just small: surprisingly, tiny fish often have a small genome too | Natural History Museum of Bern
Researchers at the Natural History Museum of Bern (NMBE) and the University of Bern have discovered a remarkable connection: certain tiny fish species not only have a small body, but also a particular...

This week we moved to Atlantic Forest, sampling Rio Branco, close to Itanhaem, with @kiewerlek.bsky.social, @drdanperkins.bsky.social, @vssaito.bsky.social and his lab

Ever heard of the five-toed worm lizard (Bipes biporus)? This critter spends most of its time underground: Each of its forelimbs is equipped with five clawed digits that are used for digging. It can grow up to 8.3 in (21.1 cm) long. Photo: franfauna, CC BY-NC 4.0, iNaturalist
How local is local adaptation? Researchers transplanted more than 700 lab-raised stickleback fish among lake and stream environments, finding that adaptation to specific sites can outweigh adaptation to broader habitat differences. In PNAS: https://ow.ly/yTOk50ZP97o

New in PNAS today: we projected how climate change will reshape the body size of marine life across the entire ocean. 23,329 mollusc species, every ocean basin. The headline everyone expects is "life shrinks." The real answer is far stranger. 🧪 #marinelife www.pnas.org/doi/10.1073/...

This issue has emerged as another threat to the Arawa lakes with PFAs being found in Lake Rotorua. The close proximity of the airport to the lake has resulted in forever chemicals being detected - raising concerns about mahinga kai sourced from the lake.

The discovery has prompted calls for more testing and raised concerns about the safety of food taken from the lake.

Worth repeating, in response to those who claim that the modern mass extinction event is overblown because many regions contain more species now than before. bsky.app/profile/ecoi...
A common (and misleading) question: "If most species invasions do not cause extinctions - and therefore increase species richness in invaded areas, shouldn't we conclude that most invasions are good for biodiversity?" Here is a straightforward answer from invasion science... 🧵
Rivers across Europe are running low on water. The Rhine, Danube and Po are at historically low levels. The water crisis is being intensified by global warming driven by the burning of coal, oil and gas. www.dw.com/en/europes-r...
Europe's rivers are drying up. Can they be saved?
The Rhine and Danube have reached historic lows. Dwindling water levels are affecting shipping, agriculture and ecosystems — and raising concerns about the future of drinking water supplies.

Summer mayfly swarms are a highly visible reminder of the progress made to improve the health of the #GreatLakes - even if it is sometimes gross to wake up to streets, cars, and everything else covered in a carpet of bugs www.statenews.org/section/the-...
Mayflies' return to Ohio isn't just a nuisance — it's a good sign for Lake Erie
An entire generation grew up without mayflies. But the pesky bug's return this summer points to a healthier Lake Erie .
