Science and illustration. Evolutionary biologist now dabbling in interspecific interactions with nematodes and arthropods.

Check out our preprint investigating host use in sympatric Caenorhabditis nematodes! We found three Caenorhabditis species in a local community are associated with different invert taxa, and document a strong association between one species and invasive nitidulid beetles.

One of the biggest tells of gen-AI ants is the waist.
I think this is because most ants belong to one of two subfamilies- Myrmicinae and Formicinae- that have very different waist structures, but the algorithms often average them into fake ants in a non-existent morphospace in between.

LLMs are, out of the box, "pretty good" at low-skill coding problems (more, if you know what you're doing). But they are not good at other kinds of problems. This is an issue when our economy is run by STEMlords who believe low-skill coders have special insight from which all answers can be derived

Why do selfing rates vary across a species’ range? In alpine monkeyflower, self-fertilization increases away from the range center, supporting the abundant center hypothesis over historical range expansion in shaping reproductive assurance.
