Sea Mink INTIMIDATES Faulkland Island Wolf!!! #UpsetCity #MightyMustelid #2026MMM

“Hardshell invertebrate” #2026MMM

Today the Falkland Islands lie 460km out in the South Atlantic, but in the Last Glacial Maximum when sea levels were lower, a shallow marine strait ~20km periodically froze over (or #IceRafts) likely allowed the canid to disperse, then become isloated from the mainland (Austin et al 2013) #2026MMM

Last up of the Night: #7-seed Falkland Island Wolf (Dusicyon australis) vs. #10-seed Sea Mink (Neogale macrodon)! #2026MMM

In the last two weeks, 1% of new NSF awards were in biology. Just one grant of 97. One. Biology in the US is on hold until there’s a regime change.

Bookstore cats are a type of library cat, right? #2026MMM

I have been looking a lot at Chalcid wasps recently- an amazingly diverse group of insects that may contain as many as 500,000 species. 🔬 They’re everywhere, but you may live your whole life without ever noticing them because they are so tiny. I think you would be missing out!

My personal favorite depiction of papyrus in New Kingdom art, showing a noble tabby aiding in the hunt, in the tomb of Nebamun, 18th dynasty. #2026MMM www.britishmuseum.org/collection/i...

We look forward to seeing you back here Monday night for Round 1 of the Extinction is Forever Division! Until then Be Well! Good Night & Good Luck #2026MMM

WOW WHAT A NIGHT! Crocodile, Mouse, Grey Fox, Eurasian Eagle Owl, Cat, Dog, White Stork, & LIONS ADVANCE! #2026MMM

TORN EAR LION SATURATES & SCOURS MOLD!!! #2026MMM

Watch out! Mold (Aspergillus) is lurking all around us, in the soil and in the air. Genome sequencing shows many infections in vulnerable patients trace back to environmental sources. #2026MMM www.nature.com/articles/s41...

Book scorpion having possibly the worst MMM day in history. #2026MMM

The tiny pseudoscorpion 'Chelifer cancroides' evolved venomous claws independently from scorpions & spiders. Proteomics & transcriptomics of its venom revealed the first genuine pseudoscorpion toxins, including brand-new antimicrobial compounds! #2026MMM pubmed.ncbi.nlm.nih.gov/34416254/

#InspirationalIntermission #2026MMM

House mice & other rodents damage library collections by chewing paper and leather for access or nesting materials and their urine & feces contaminates & deteriorate library materials. Their activities can also attract or facilitate other library pests and organisms. #2026MMM

Next Up: 8-seed European Rabbit (Oryctolagus cuniculus) vs. 9-seed Mouse (Mus musculus) #2026MMM

Is Silverfish really gone? Nope. A global analysis of indoor silverfish species shows they thrive in human buildings and keep spreading by hitchhiking with cargo. The silverfish invasion may be just getting started. #2026MMM #RIP academic.oup.com/jinsectscien...

NEXT UP: #4 seed Eurasian Eagle Owl (Bubo bubo) vs #12 seed silverfish (Lepisma saccharinum) #2026MMM

LIBRARY CAT DEFEATS BAT! #2026MMM

They're not always helpful #2026MMM

Up next: 6-seed cat (Felis catus) vs 11-seed common pipistrelle (Pipistrellus pipistrellus) #2026MMM

#2026MMM #LibraryDivision #TeamNileCrocodile Art by Charon Henning @oddangel.bsky.social

NILE CROCODILE OUTLASTS PAPYRUS!! #2026MMM

First Up: #1-seed Nile Crocodile (Crocodylus niloticus) vs. #16-seed Papyrus (Cyperus papyrus) #2026MMM

Maxombe et al. (2022) used SE African Papyrus DNA (n = >1000) to test the unidirectional dispersal hypothesis (i.e. pops downstream have ⬆️ diversity than pops upstream). Results = no! Looks like Holocene climate & demographic dynamics shaped genetic diversity. www.nature.com/articles/s41... #2026MMM

Please help my colleagues, who are working on an important survey! #NaturalHistory

The Baby made this for Lara as runner up/gorilla advancer. Sound up for the thank yous. #2026MMM

It is week 1 of #2026MMM and also marks my 10th year as a narrator which is wild! Learned abt the adorableness of the bear cuscus, weirdness of the crypt-keeper wasp, beauty of Aphrodite fish, amazingness of the leaf slug, oh & did i mention adorableness of the bear cuscus!

Arthropod Photo of the Week: March 11, 2026 Owlfly Ascaloptynx appendiculata Neuroptera: Ascalaphidae Observed in Arizona, USA By Tom Astle (@tjalamont.bsky.social), California, USA #arthropodPOTW

This is so so upsetting. So Grammerly is violating the memory of bell hooks AND making AI versions of the rest of us before we're even dead. Someone tell me who to sue, not even joking.

Chaos reigns, post rare snoots

Look at those mitts! This Vancouver Island marmot is only a few months old, and its paws and claws are oversized for a diminutive little pup! The large paws are needed for digging in the rocky alpine soil of their home.

DID YOU KNOW ABOUT THE CAMEL MOBILE LIBRARY?! Each issue of the #2026MMM MMMagazine gives the science behind the battle, but also has so much more! Last night's LIBRARY column led by Janice Hermer, explained how no matter your interest, there's a library for that! libguides.asu.edu/MarchMammalM...

Great logo for the 1995 Evolution meeting in Montreal.

Grammarly will keep using authors’ identities without permission unless they opt-out

I guess I never did post my #2026MMM bracket! I got a picture before submitting it to the lab pool. Team Mustelid all the way!

Annnnnnnnnnnd the first Mr. Rufous of 2026! Let the games begin! #birds #becurious 🪶

#2026MMM WILDCARD WINNER: Assassin Bug! Join us Wednesday, March 11th at 8PM EST for ROUND ONE of MONEY MAMMALS!

The subfamily Reduviinae (Assassin bugs) is a taxonomist's nightmare. A molecular phylogeny done by Hwang & Weirauch (2018) reveled it is polyphyletic, meaning the group doesn’t share a single recent ancestor. doi.org/10.1371/jour... #2026MMM

FIRST & ONLY UP TONIGHT: Bone Collector Caterpillar (Hyposmocoma) vs. Assassin Bug (Acanthaspis petax) #2026MMM

Tonight is the WILD CARD, the play-in to the big show, an amuse-bouche, or rather an amuse-esprit, for the discerning #2026MMM palate as we gear up for the tournament of tournaments! #2026MMM
