After 4+ years of work, our article on Austropotamobius is out! We traced their 30-million-year journey across Europe, discovered hidden lineages, and finally solved some long-standing evolutionary puzzles. The key highlight? A. bihariensis from the Apuseni Mts: a small crayfish with a big story.

The Taxonomic Distinctiveness Hypothesis (Ricciardi & Atkinson 2004) predicts that invaders with no relatives in an area will have the largest ecological impacts. We found evidence of this for various aquatic systems. It is also supported by terrestrial studies. Eco-evolutionary context matters!

At #EOU2025 @eounion.bsky.social conference next week, we'll show new evidence implicating forestry in declines of British Marsh Tits during the era of woodland conversion in 1950/60s-1980s. This was period of steepest decline in Marsh Tits. Why? What was going on back then? #ornithology 1/5

Blessed to find this beautiful electric blue Faxonius virilis while sampling the St. Lawrence for my doctoral work! This is a fairly rare phenotype for this native North American species!

1/ A 🧵 on some recent research by our lab on invasive crayfish: Sheppard et al (2024) found that projected climate warming in the Great Lakes will reduce the maximum feeding rate & increase the frequency & duration of gravid states of marbled crayfish. Read: redpath-staff.mcgill.ca/ricciardi/Sh...

No, I'm not going to give you food just because your head is disproportionately large compared to your body. Calm down. go beg another human.

How hard is it to get rid of unwanted cloning marbled #crayfish? Marbled crayfish were released into 1️⃣ pond in Prague. The pond got drained. Collected every visible crayfish. Nope: still crayfish. The pond got drained AGAIN. Collected every visible crayfish AGAIN. Nope: still crayfish. 1/4

the new developments on inat inspired me to make a diagnostic thread for every insect order because there's only like 30something of them. going to try and avoid exceptions and extremely technical characteristics when possible. 🧵
