Standing host genetic variation typically protects in case of disease invasion, right? Well... Exploring implications of my new paper with @sabarra.bsky.social , a thread (1/5).

The figure is divided into a left panel titled "Resistance variation" and a right panel titled "Tolerance variation". The left panel shows a frog labeled "Disease-free" with a gold arrow labeled "R0 > 1" and "Invasion" leading to a frog with fungus shown on it labeled "Endemic". There is a purple arrow labeled "Evolution" and "R0<1" leading from the Endemic frog back to the Disease-free frog. The right panel is labeled "Tolerance variation" and has the same Disease-Free and Endemic frogs. There is a purple arrow labeled "R0<1" and "Failed Invasion" leading from the Disease-free frog and curving back to it. However, there is also a gold arrow that splits off from the purple arrow. The gold arrow is labeled "Evolution" and "R0>1" and leads to the endemic frog.

New paper: We know the minority of hosts hold the majority of macroparasites (aggregation). What about fungal pathogens? Turns out, they are MORE aggregated than macroparasites, lognormally distributed, and the distribution carries signatures of epidemic stage.
