New paper alert: A time-calibrated phylogeny of Neotropical freshwater fishes, the most diverse continental fauna on Earth.

Built from a supermatrix of 51 genomic markers for 3,167 species, the most species-rich phylogeny of this fauna to date.

Seems worth noting this award in light of the present circumstances. Get the troops out of our fair city please, perhaps after they enjoy a great Malnati’s pizza!

The C-value paradox: no simple correlation between the total amount of genomic DNA (C-value) and perceived biological complexity.

If conservationists work from a compromised baseline, our notions of abundance, scarcity, and ecological wellbeing will keep getting defined downward:
"The researchers show that using the 1970s as a baseline tends to normalize an already severely degraded state."

Bird conservation threatened by shifting baseline syndrome
New research shows that populations of dozens of waterbird and seabird species have been declining for much longer than previously thought in Europe. The article "Shifting the baseline for waterbird a...

The transition of vegetation from the lowly water-stressed forest with high tree cover to a savanna-grassland regime with low tree cover and the utilization of rootzone storage capacity to cope with the spatial change to a drier climate.

🐟 Not all fish are cold-blooded! New research led by @arciladk.bsky.social, curator of the Marine Vertebrate Collection & recent PhD grad Fernando Melendez, explores how ecological interactions + evolutionary innovation reshaped life in the ocean. 🌊

I get that the news cycle is packed right now, but I just heard from a colleague at the Smithsonian that this is fully a GIANT SQUID BEING EATEN BY A SPERM WHALE and it’s possibly the first ever confirmed video according to a friend at NOAA

“Ecuador’s plans to auction new oil blocks in the Amazon are doomed to fail. Indigenous resistance, civil society mobilization, & growing international pressure will continue to expose these projects as illegitimate, unlawful, & unfinanceable.”-Kevin Koenig of @AmazonWatch apnews.com/article/oil-...
Indigenous groups criticize Ecuador’s $47 billion oil expansion plan in Amazon
Ecuador’s plans to offer dozens of blocks of land for oil exploration for more than $47 billion has prompted opposition from seven Indigenous peoples in the Amazon.

It really helps to think of all vertebrates as fish. The position of the anus is a very stable feature of the vertebrate body plan, indicated by the red arrows in these images of embryos in four species.

The position of the anus is a core feature of the vertebrate body plan. And there are really no other landmarks on the belly side of a developing vertebrate to help guide gene expression and cellular differentiation.

A new study shows that the earliest gobioid fishes were coral-reef associated dwarfs. Results suggest that dwarf gobies achieved ecological success early in gobioid evolution, arising through convergent evolution across different lineages🐟 Read more: buff.ly/GVMpJaF

Earliest gobioid fishes were coral-reef associated dwarfs: New evidence from the Eocene of Monte Bolca, Italy
The earliest skeleton-based gobioid fish, the minute goby †Carlomonnius quasigobius Bannikov and Carnevale, 2016 (13 mm standard length), originates from the Lower Eocene coral reef fish assemblage...

Although chromosome-level macrosynteny is broadly conserved among cypriniforms, we demonstrate that microsynteny can resolve deep phylogenetic nodes. Both sequence-based and microsynteny-based analyses find that Gyrinocheilidae is the sister lineage to all other cypriniforms
