If you like matrices + microbes, have I got the paper for you. Work with @janamassing.bsky.social, @jdyeakel.bsky.social, and @thilogross.bsky.social out today in @royalsocietypublishing.org! We study dynamics of cooperative bacteria without specifying a conventional model: doi.org/10.1098/rsif...

Yes HORs are good, the loss of generalizability is what I was referring to πŸ˜ŽπŸ‘πŸ½

Yes, I meant the extra complicatedness is not good! Not that we should ignore HORs

This should be an important result for ecology. Higher-order interactions are becoming increasingly popular to study, but that appears to be... not good

Graphs are maximally expressive for higher-order interactions We demonstrate that graph-based models are fully capable of representing higher-order interactions, and have a long history of being used for precisely this purpose. This stands in contrast to a commo...

New on the arxiv:

β€œGraphs are maximally expressive for higher-order interactions”

We clarify central misconceptions in the recent literature on "higher-order networks".

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.

NSF is open again!

A few comments:

*Please be patient.
During a shutdown NSF employees cannot open computers or respond to emails.

*Merit review will continue. However panels won’t resume until after Dec 8th.

*POs remain excited and committed to advancing science and the scientific workforce.

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!

You've heard of Bacon numbers, Erdos numbers. Who is it for ecology? I bet most have a Levin number < 3.

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. πŸ§΅πŸ‘‡
