I have started my postdoc @vogelwarte.bsky.social, working on Black-headed Gulls and avian influenza. I am very grateful for the trust in my proposal, and excited to continue my work on gull winter ecology.

What started as a chance observation turned into a rabbit hole into an ancient arthropod lineage, whose members live in almost every house, yet we know so little. Very happy to see that manuscript out. Thanks to co-author Nikolaus Szucsich and helpful reviews learned a lot in the process!

A new study combining literature reviews, specimen collections, and citizen science data from #iNaturalist and @gbif.org documents 3 native and 3 non-native #species of Zygentoma ( #silverfish and allies) in Switzerland. Check out the full study and how and where these #species are thriving:

Earth's largest land animals are limited by salt. Sodium availability constrains the density and distribution of elephants, giraffes and rhinos across Africa, and offers a new explanation for the so-called 'missing megaherbivores'. www.nature.com/articles/s41... Free access: rdcu.be/eTPY2

Beavers create habitats for bats
A study shows that land animals benefit from beaver dam construction – for example, endangered bats.

Beavers boost bats! Beaver ponds had higher bat richness (4→5 spp/night), 1.6× activity, and 2.3× feeding vs. controls. Structural changes (standing deadwood, more heterogeneous canopy) and more prey help explain why: Journal of Animal Ecology: besjournals.onlinelibrary.wiley.com/doi/10.1111/...

BEHOLD! One of Earth's greatest lineages of life: the lil wiggle arm guys, Meteora. These single-celled critters, originally found in deep-sea sediments, are SO DIFFERENT from other lifeforms on Earth that they're likely in their own kingdom (as in, the Animal Kingdom, the Plant Kingdom etc). 🧪🌿

Thanks to everybody who chimed in! I arrived at the conclusion that (1) there's a lot of interesting stuff about interactions and (2) the figure I was looking for does not exist. So, I made it myself! Here's a simple illustration of how to control for confounding in interactions:>

🚨 Stat tips 🚨 Are you aware of the regression to the mean #RTM effect? This artefact is often overlooked in #ecology & especially in biodiversity resurveys 🌳🍄🦔🦅🦎🦋🐝🐞 It basically shows up each time you investigate changes between 2 time events: t2 vs t1 Let me unfold it for you 🧵

New #research! Trying to find the true winter abundance of #Black-headedGulls in Switzerland, we organised a national count - at the overnight roosts! With this method, we recorded with 39'000 gulls about 20 % more than during the traditional (diurnal) water bird counts

1/ I'm constantly amazed at the naivety of so much of conservation science (& other mission-driven disciplines) As if all we have to do is generate the evidence and society's leaders will use it to do what's needed As if there's no-one trying to make sure that doesn't happen
