JD Vance claims that diversity weakens unions, as people end up distrusting each other and not organizing.

Let me tell you two menswear stories related to this claim. 🧵

New study from Ty Loft’s PhD thesis. We used an energetic approach to quantify, acr sub-Saharan Africa, how mammal- and bird-mediated ecosystem functions have changed. We found that overall trophic energy flows have decreased by more than one-third, but this change varies across biomes and land uses
Energy flows reveal declining ecosystem functions by animals across Africa - Nature
An ecosystem energetics approach, quantifying trophic energy flows across species, offers a unified framework for linking animal biodiversity loss to changes in ecosystem function and Earth system pro...

Our new paper in Nature uses ecological energetics to track ten ecosystem functions of all birds and mammals in sub-Saharan Africa. It shows that the ecological power of African wildlife has declined by a third since pre-colonial times @natureportfolio.nature.com

🌍 New Oxford-led study in Nature finds Africa’s wildlife has lost a third of its natural “power” — the energy driving ecosystems and livelihoods.

Large animals once sustained this flow; their loss now reshapes life across the continent. @ymalhi.bsky.social

Rights of Nature laws shift Nature from object to subject-but turning ideals into impact depends on legal detail. Ecuador’s bold vision, NZ’s guardianship model: both inspire, but face challenges. Curious how principle meets practice? Read our intern's blog on RoN in action 🌿

Using a novel method to visualize in situ underwater sound, Dantzker et al. have developed a technique that combines visualizations of spatial audio with concentric 360° video recordings 📹 🌊 Read more here 👇

🌍 🧪
Ascribing sounds to individuals. The UPAC-360 can isolate which individual is the sound source in a coral reef. Here, we identified at least 121 individuals from six species, including 58 Stegastes partitus, greater than 53 Azurina multilineata, 1 Lactophrys bicaudalis, 1 Halichoeres garnoti, 2 Canthigaster rostrata, and 5 from the family Gobiidae. The 3 dB zone overlaps only one individual S. partitus. The region of the powermap around the focal individual has been removed to show the fish, but at this moment it is moving quickly so the visual ID is based on video before and after the soniferous event (Movie S1). The bottom left shows the Blue Robotics housing for the recorder.
