9000 words down, somewhere around 30,000 words to go. This weekend I will be locking myself away to work on Chapter 1, which will be a highlight reel of animals commonly found in north American cities.

Moeten mensen zich zorgen maken om de vogelgriep?

Wie van jullie zien we op de #LandelijkeDagSovon? Wij ontmoeten je graag!

Do you know how crayfish arrived to the Iberian Peninsula? Tomorrow I´ll be describing the introductions of the Italian crayfish in the 1580s and the red swamp crayfish in the 1970s Historical events with long-lasting biodiversity effects 14:30 Lisbon time Link & details below @ebdonana.bsky.social

“Een kwart van de onderzochte levende eenden in Nederland draagt de zeer besmettelijke vogelgriepvariant H5N1 met zich mee. Dat is het hoogste percentage besmette wilde vogels dat ooit is vastgesteld.” www.nrc.nl/nieuws/2025/...

Some of the #GreatLakes most damaging invasive species - like zebra mussels + round gobies - were introduced via ballast water. However, ballast water management systems on ships have been shown to reduce the abundance of living organisms in ballast water by more than 98% www.wpr.org/news/conflic...

Beyond Chicago's charismatic exotic animals (shout-out to Chance the Snapper), the city's waterways have also become home to less conspicuous - but environmentally harmful - exotic species like weatherfish, goldfish, and red swamp crayfish. A good reminder to never release pets to the wild!

I’m Detroit, Michigan for the 3rd Binational Great Lakes Aquatic Invasive Species Forum and needed to share pictures of this amazing carousel I spotted along the Detroit Riverwalk! 🐟

Any thoughts @drfishsg.bsky.social? (I bet @solomonrdavid.bsky.social would say “Release the gar and bowfins!”)

A reminder, from the 2023 IPBES assessment of invasive alien species. www.theguardian.com/environment/...

Another reminder: Biological invasions are at least as costly as earthquakes, floods & wildfires. Their prevention deserves similar precautionary investments as those applied to extreme natural hazards. #bioinvasions www.sciencedirect.com/science/arti...

The term 'invasive' (wrt #bioinvasions) remains inconsistently applied. In the 1990s, legislators began defining 'invasive' with an impact criterion - to identify a subset of nonnative species to be managed. The definition I prefer is based exclusively on the process of spread, as explained below:

In the British Ecological Society magazine 'The Niche' (Winter 2020), Phil Hulme wrote a nice review of our new edition.

"When ecosystems fail, supply chains stall, costs spike, and financial stability is eroded. The World Economic Forum ranks biodiversity loss and extreme weather among the decade’s top global risks.  Yet, most companies leave nature out of their strategic plans." www.eco-business.com/opinion/busi...

A common claim is that zebra mussels "clean" lakes. They can certainly clear the water column but also create conditions that reduce oxygen & promote toxic algal blooms: phys.org/news/2021-06... www.canr.msu.edu/news/telecou... cdnsciencepub.com/doi/10.1139/... www.greatlakesnow.org/2021/07/rese...

I spent yesterday learning how to ID Michigan's native freshwater mussels in a free workshop led by the state's top experts - 2 retired dudes sharing their accumulated knowledge of these fascinating animals DYK mussels use a lifelike lure to attract fish, which are hosts for their parasitic larvae?

Michigan lawmakers want to greatly increase funding for invasive mussel control research in the #GreatLakes to $500 million over the next 10 years - as Great Lakes Fishery Commission's Greg McClinchey says in this article: "Mussels are this generation’s sea lamprey" bridgemi.com/michigan-env...

New study reveals rats, not just humans, drove Easter Island's deforestation. The invasive rodents devastated palm forests through relentless seed predation. The real lesson is about unintended consequences when invasive species enter vulnerable island ecosystems medium.com/the-academic...

And gar are suspected to have an unusually strong DNA repair apparatus, which, if proven by further studies, could aid in developing treatments against diseases like cancer. If all this isn't enough to convince you of their awesomeness, you need to follow @garlab.bsky.social to set you straight 8/8

Love sturgeon? Come hang out with us in Bay City on December 12 for a screening of the brand-new short documentary, "Dinosaur Fish"! The free, public event will include a Q&A panel with folks who are working hard to restore lake sturgeon in the Saginaw Bay area. Details: buff.ly/Tu9qRtM

@solomonrdavid.bsky.social This just landed in my feed on YouTube. My first thought was "I wonder if you know about this?" 20 seconds later I had my answer...

Some creature features! #GarWeek

And a few more facts. Happy #GarWeek!

#WaterYear celebrates #GarWeek and also celebrates @solomonrdavid.bsky.social for being such an effective communicator about, yes, gars, but really fish and freshwater ecosystems more broadly. @garlab.bsky.social

This is brilliant

Not much is scarier for a #GreatLakes fish than the invasive sea lamprey, sometimes called vampire fish 🧛 But while they're more trick than treat in their introduced range, they're actually threatened in parts of their native range of the Atlantic coasts of Europe + North America - that's scary!

Lampreys definitely fit in the “creepy but cool” category. Bonneville Fish Ladder viewing window, Oregon.

1/ Carlton & Cohen (1993) described the global transport of species as "ecological roulette" (www.science.org/doi/10.1126/...), whereas Paine & Zaret (1973) equated the introduction of non-native species to ecological gambling (jamanetwork.com/journals/jam...). #bioinvasions #invasivespecies

BEHOLD the GARgantuan Alligator Gar!!! This is the largest Alligator Gar I’ve encountered; at over 7 feet 10 inches (240 cm) and approximately 55 inches in girth, its weight is estimated at 300 pounds (136 kg)! A true river monster, among the largest caught, tagged and safely released! #GarWeek
