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

What an awesome event! 🎉 Huge thanks to our panelists for sharing their journeys & tips on navigating the government job market. 💼 We’re sure all our AFS attendees left inspired (and maybe a little ready to conquer the job world)! 🚀

Freshwater sponge spicule - about 100micrometres or so. Photo taken down the scope, then I had some fun in photoshop :))

Pectinatella magnifica
Found this blob thing floating in Lake Tomahawk in Black Mountain. Turns out it’s a living…um organism, called a Magnificent Bryozoan! Google it…amazing! New to me, I was scared of it. Turns out to be a sign of a healthy lake. #blackmountain

Entomologia Terrae Novae is an unpubl. manuscript by Philip Henry Gosse (1833) on the insect fauna of Newfoundland.
The ms (which has been digitized in the Biodiversity Heritage Library) was returned to Newfoundland a few years back.See the story and the link to the book at s.si.edu/2rjaVvV

Why microplastics should be routinely sampled by limnologists.
No environmental field survey that has searched for microplastics has yet failed to detect their presence. They are omnipresent in the water column, in the sediments, and in aquatic food webs.

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:

Predicting an invader's impact is the holy grail of invasion ecology. The greatest challenge to prediction is context dependence. #bioinvasions
My students & I often incorporate context dependence into experiments & models, to test the influence of key environmental variables.

Since the time I was a grad student it was apparent that context dependency posed a major challenge to predicting the ecological impacts of invasion. The St Lawrence River has been my outdoor laboratory for studying impacts of Ponto-Caspian species (zebra mussel, quagga mussel, round goby, etc). 1/🧵

This aquatic insect is commonly called a water scorpion or water mantis. It is a true bug (hemipteran) of the family Nepidae. Genus: Ranatra.
Water Stick-insect at RSPB Saltholme today. This predatory bug (not a stick-insect!) has expanded its range rapidly northwards in recent years. In the late 1990s it reached Nottinghamshire before moving into Yorkshire around 2000. By 2023, it was into Scotland.
