Reptiles with longer Wikipedia pages tend to be bigger. The relationship is a power law with exponent = 0.85. I guess humans really like writing about big lizards? The longest article is the Komodo Dragon.

UC Berkeley Law creates new AI policy that bans AI for "conceptualizing, outlining, drafting, revising, translating, or editing any work submitted for credit" or exams because "thinking remains the sine qua non of good lawyering (and of a quality legal education)." That's what I'm talking about.

Body size constrains trophic interactions, shaping the feasibility of species' populations. Over macroevolutionary timescales, these constraints feed back to shape selection on body size and diet. We...

Paper alert! Our study about functional motifs is out in PNAS. We use food webs as an example to discuss how small subgraphs drive the dynamics in complex systems. While motifs that determine overall stability are rare, when it comes to reactivity, we show that small groups dominate system behavior.

We are doing spatial patterns in class tomorrow. So please enjoy my simulation of Pokemon battles on a lattice. Pokemon attack a random neighbor and winners are based on the game's hierarchy (water > fire > ice ...). Some amazing spatial patterns emerging from 7-way rock-paper-scissors!

With sadness and respect, we honor the legacy of Dr. Jim Estes, who passed away this week. A pioneer of marine ecology, Jim’s groundbreaking work transformed our understanding of ecosystems and the essential role of keystone predators like sea otters. He is an icon in sea otter research. 🧵👇
