New Jersey city expands its urban forest, trains residents to care for the trees » Yale Climate Connections The We Grow Camden initiative aims to plant 3,000 trees across the city.

Trees cool neighborhoods, filter air pollution, and soak up stormwater. In this city, they also represent the idea “that the future is worth nurturing,” says Justin Dennis of the Trust for Public Land.

Dragonfly Wings: Marvels of Strength, Durability A group of researchers examine a variety of chemical and structural qualities of dragonfly wings to seek inspiration for human technical innovation.

Thinner than a human hair, dragonfly wings are highly durable, w/ antimicrobial, water-resistant, and anti-reflective properties and more. In a new study, researchers examine a variety of chemical and structural qualities of dragonfly wings to seek inspiration for human technical innovation.

Why Are So Many Pedestrians Killed by Cars in the US? It’s unfortunately not uncommon for pedestrians to be killed by cars in the US.

Deep dive into the surge in US pedestrian deaths:

"It’s not that more pedestrians are getting hit by vehicles; it’s that the ones that are getting hit are more likely to die."

"[That] seems like fairly strong evidence for the theory that the rise in large SUVs is behind the uptick in ped deaths."

Really enjoyed the opportunity to come on @thepulse.whyy.org and chat with Maiken about the wildlife trade!

Perverse market incentives related to the desirability of rare items are pushing the European eel to extinction, by favoring its exploitation despite extreme scarcity

i know it's self-evident in many ways, but the role that traditional grading regimes play in this somehow feels under discussed. we can (rightfully) wax poetic about how the main point of assignments is the process of doing them, but the way we use grades often fails to reflect this

Banning wildlife trade can increase trade of other threatened species Wildlife trade bans can encourage buyers and sellers to trade in similar species that haven’t been banned but may still be endangered.

New study! 🚨 Banning wildlife trade can increase trade in other threatened species 🚨

We find Japan’s ban on 3 species led to rise in trade of others. Bans alone aren't enough—we need consumer insights & monitoring to avoid shifting overexploitation elsewhere.

Global wildlife trade is an enormous market – the US imports billions of animals from nearly 30,000 species Understanding the number and origin of animals entering a country is important to control the health and ecological problems imported wildlife can bring.

Most #wildlife trade is legal, and the U.S. is a major importer. Many wild animals, like reptiles, spiders, clownfish, chimpanzees, and tigers, become pets, while thousands go to zoos and aquariums. Experts in #sustainability, #ecology, and #biology dive into the numbers:

Scientists are tracking global wildlife’s contributions to humanity In October 2020, the hoofbeats of American bison thumped across the prairie of the Rosebud Reservation for the first time in more than a century. Years in the works, the release of 100 bison (Bison bi...

New research assesses in detail the contributions of wildlife to people.

Humanity relies on an array of ecosystem services for well-being and survival, but the provision of these services rely not just on vegetation but also the wild animals that inhabit the ecosystems.

New on global conservation science:

Wildlife trade might drive species to extinction when people are willing to pay more for the last individuals but forecasting such effects on threatened species requires more evidence.

Its always a bit shocking to consider the risks the US takes in invasive vertebrates via the exotic pet trade. With a ton of great colleagues, we identify the species that are highest risk.

Maps and graphs of range contraction over different dynasties

This is so cool - this study used Chinese poetry to reconstruct 1400 years of range change for the Yangtze finless porpoise, and showed that most of the range loss happened in the last century

No instructor I know (who isn't a miserable asshole) WANTS an adversarial relationship with their students. We just want you to actually learn the material, & understand why it's important to do so. We want you as robustly capable as we can manage, on the other side of our time with you. That's it.

Principles of experimental design for ecology and evolution Here I argue that we do not discuss experimental design, often until it is too late. This editorial seeks to begin a conversation about how and where to replicate appropriately.

I wrote (ranted) on experimental design as I was frustrated as an editor at how little guidance students were getting. I underestimated the interest in the issue: it has been downloaded 10,000+ times! Clearly it’s something we need to be talking about more. onlinelibrary.wiley.com/doi/full/10....

The last paper from my dissertation is out today in @consletters.bsky.social! Economic theory predicts that people's love of rarity can drive species in the wildlife trade extinct. Here, we ask: is this actually happening? How can we monitor it?

Fellow biologists: We must be active and vocal advocates for the support of the humanities & social sciences. Biology is enhanced by its inherent transdisciplinary connections, including understanding historical context, identifying modern-day applications/implications, & enabling future innovation.
