Interested in the marbled crayfish (Procambarus virginalis) and its invasion potential?
Have a look at our recently published biological synopsis, led by @vanmierlo.bsky.social

The Brushnose Crayfish (Procambarus pubescens), named after the prominent setae (hairlike structures) on its rostrum.

Of course, happy to help! :)
Female! The structure I circled is the annulus ventralis, which is the female reproductive structure.

The next crayfish world congress will be in New Orleans LA: www.iaa25.com
New Issues of Freshwater Crayfish is out. Has an article by yours truly and B. Schryer on the invasive WRCrays.
Get excited! NEXT IAA is in New Orleans and registration is open www.iaa25.com

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

A single orange Queen butterfly sits dead center of the photo, sitting on a single outstretched flower at an angle from another series of stems that run mostly the opposite way diagonally. Background is blurry greens, yellows, and whites with a hint of a white fence. Photo is very grainy.
Good morning everyone!
Here's a happy little butterfly #scape for #FlowersOnFriday 🦋🌞
Hope you have a great weekend ahead 😎

Astacopsis gouldi
An astacology (crayfish) episode is needed!! @drecrevisse.bsky.social @ericrlarson.bsky.social @ecoinvasions.bsky.social, Dr. Brian Roth (Michigan State University), Dr. Checo Colón Gaud (Georgia Southern University) and Chris Lukhaup would be great picks!
Blue female Faxonius virilis from the St. Lawrence river.
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.
