While preliminary, these results are promising for crayfish systematics, evolution, and conservation efforts.

Another fun project the lab is researching is to determine the effectiveness of anchored hybrid enrichment in resolving the crayfish tree of life. As part of these efforts, Dr. Meng-Chen Yu and I have been learning bioinformatics and had an opportunity to present our efforts earlier this week. 🧵

Field work is exciting but it is often the first step of many in research. Fortunately, as part of my postdoc training with Dr. Keith Crandall and Dr. Marcos Perez-Losada, I have multiple projects I am contributing to at various phases. 🧵 #GWSPHResearchDay2026

Releasing an ovigerous Lacunicambarus ludovicianus (Painted Devil crayfish).

It was a great time doing some field work in my old stomping grounds! A huge thank you to Dr. Andreas Kautt and his lab for helping me collect multiple crayfish in MO. Dr. Keith Crandall and I are continuing collaborations with Dr. Kautt's lab to characterize microbiome shifts in captive crayfish.

82% fewer invasive crayfish in Italy 🦞📉

#GuardIAS is proving that precision trapping and community action can stop the red swamp crayfish in Tuscany & Lombardy.

The IUCN Uproar Challenge at the Indianapolis Zoo is now up and ready for your votes: uproar.indianapoliszoo.com

The Sweet Home Alabama crayfish needs your vote for freshwater crustaceans conservation efforts! Please spread the word.

The second paper of the year and an important piece of the puzzle for the conservation of the Hardin crayfish and its federal review process. While we come away with more questions than answers for this paper, we continue to move conservation efforts forward.

A fun project with great folks!

Finding multiple crayfish at the National Aquarium was a major highlight for my visit. Much to my roommate's entertainment, I stood by the crayfish and talked to multiple folks about these guys. It is rare to find crustacean diversity represented at aquariums, much less freshwater diversity.

I wouldn't be where I am without so many talented and supportive women in science. Women who pursued science before me, who pushed my boundaries, who opened the door - THANK YOU! You pushed the line back for me.

Bruce Springsteen - Streets Of Minneapolis (Official Audio) YouTube video by Bruce Springsteen

I wrote this song on Saturday, recorded it yesterday and released it to you today in response to the state terror being visited on the city of Minneapolis. It’s dedicated to the people of Minneapolis, our innocent immigrant neighbors and in memory of Alex Pretti and Renee Good.

On a Spiny cheek crayfish!

Sarah’s page of notes which says “tanner mierow: gobies and shrimp have murualisms in which shrimp dig burrows and gobies play lookout.” A shrimp thinks “why u so obsessed with me?” Then words “who initiates this partnership? Gobies ask out the shrimp” and then a shrimp with hearts alll over it and labeled lover boy. Words say “gobies initiate but shrimp maintain” and “gobies are desperate for a shrimp”

Heard from Tanner Mierow at #SICB2026 about the mutualisms between snapping shrimp and gobies.

Gobies need shrimp to dig holes. Shrimp need gobies to keep a lookout.

But who asks who out here?

Gobies initiate- they’re *desperate* for a shrimp. But once initiated, shrimp maintain the relationship.

Tapper: This is one of the documents the DOJ released. It’s 100 pages. It’s all black. That’s the transparency we’re getting.

The Marbled Crayfish. Be on the lookout for this invasive asexual species in Ontario/all of North America ! Report any sightings immediately.

Its official, official! #tntechgrad #phdgraduation #tntechstreamfishecology

Absolutely had a blast at my last SFC as a student. I love catching up with friends, mentors, and hearing about all of the great research happening throughout the southeastern U.S. While I didn't get hardly any pictures, there was lots of laughter, celebration, and good times had by all.

Biodiversity concerns set to be the next frontier after climate change With the rise of natural capital initiatives such as the TNFD, systemic risk issues related to ecosystem collapse will soon receive the same amount of attention as climate change

In the 1960s NATO scientists treated biodiversity as a strategic asset. Inspired by Charles Elton, they viewed complex ecosystems as being less vulnerable to disruption by warfare: www.nytimes.com/2013/05/30/o.... Now economists are recognizing risks of biodiversity loss www.iflr.com/article/2a63...

I love starting a new project with great people. A huge thank you to WLU Crayfish Lab for helping me start things off with a bang! We successfully captured crayfish, passed some skills on to students, and enjoyed the comraderie.

A Hooded Merganser duck holding a freshly caught crayfish in its beak. The Hooded Merganser has a black head with a white patch on the top rear of its head. It has striking yellow-orange irises, and their eyes can account for the diffraction of light underwater while hunting.

From the National Audubon Society's FB page: "The Hooded Merganser is a handsome diving duck with a taste for crustaceans, small fish, and aquatic insects. Their eyes are specially adapted to account for light refraction underwater, making them fearsome—but undeniably beautiful—hunters of crayfish."

I am pretty happy about the way things are going.

That's certainly possible. Weird things during regeneration and I suspect failure happens more than we realize.

Educated guess - maybe early regeneration gone wrong? Or the chelae formation isn't fully developed yet and is waiting for a molt?
