Check out @sulheim.bsky.social's paper! The latest from our lab showing that some species do actually coexist robustly, no matter what or how much you feed them, whether the environment around them is constant, and whether or not they depend on each other metabolically for amino acids and vitamins.

Question for evolutionary biologists. Am I missing something or are Fisher's geometric model and Simpson's adaptive landscape model exactly the same thing? And why has nobody said so? If you know a paper that makes this point even tangentially, pls let me know. #evolution #popgen #quantgen

Beautiful new pre-print by @lambdapp.bsky.social! Rather than asking whether microbial interactions are mainly positive or negative, Prajwal asks: how strong or weak are they and why? The answer: not Gaussian, but skewed. This is similar to larger organisms, but not for the same reason. Read it!
