Emperor Penguins Are Now Endangered, a New Assessment Finds

Emperor penguins, those icons of the Antarctic, are now endangered. As are fur seals. The cause is climate change.

A fish with trans flag colors saying trans rights and text below that says you bet your wrasse

Happy trans day of visibility, here is a wrasse design I made awhile ago because all wrasses change sexes as they age.

I’m finishing my tenure as Chief Meeting Organizer for the Evolution Meetings. Apply to replace me!

Without a doubt, this is my favorite service I’ve ever done. In trying times, it was a real balm to get together weekly with a group devoted to making the best meetings we can for students.

Congrats to my student Eva (co-advised by Dr. Susan Washko) who successfully defended her thesis on macro-invertebrate community composition in high-elevation fens impacted by mining in the San Juan Mountains pre- and post-restoration. Wanna see a beautiful field site?

Chinook salmon found naturally hatching in Upper Klamath River for first time in a century The Klamath Tribes are celebrating evidence of Chinook salmon spawning in Klamath River tributary.

Last year, researchers documented the first adult Chinook salmon in a tributary of the Upper Klamath since dam removal. This spring, they've discovered newly hatched salmon, lifting hopes of a cultural renewal for Klamath Tribes members.

Colon cancer now leading cause of cancer deaths under 50 in US Experts warn younger people not to dismiss symptoms such as rectal bleeding as diagnoses rise for those under 50

I’m quoted in this important Guardian article by @whatsitlike.me about colon cancer. I got the bad news today that chemo didn’t do the trick after 24 treatments. I start immunotherapy next week. Get tested folks; don’t ignore your health.

No such thing as a shark? Genomes shake up ocean predator’s family tree Sharks might not be a natural biological group, with most species potentially closer kin to rays than to an oddball group of sharks.

The rarest of the rare! This holy-grail dream fish is a larval-stage #monkfish, aka #goosefish.

Shot in the wild, using scuba, while diving at night over water several thousand feet deep, several miles offshore from Kumejima, Okinawa.

No animal alive today is ‘primitive’ – why are so many still labeled that way? All species alive today, from chimpanzees to bacteria, are cousins that each have equally long lineages, rather than ancestors or descendants of one another.

The idea that humans sit atop an evolutionary hierarchy dates back to 1866, when a scientist drew the first tree of life with "Man" at the top. This inaccurate view still shapes how we think of the animal world, despite decades of genomic evidence proving evolution has no hierarchy.
