Can a tiny magnetic sensor help geolocate migratory birds? 🧭 Earth’s magnetic field varies across the globe in both intensity and inclination. We asked whether those spatial patterns can turn magnetometer data from lightweight tags into location estimates.

how does seasonal migration evolve? this question is to the heart of our focus and here we use common garden approach to characterise the amount of seasonal change in chromatin accessibility in ancestral migratory and derived resident populations of the Eurasian blackcap doi.org/10.1098/rstb...

Removing outliers is one of the first things to do when analysing movement data. With porting the remaining move functions to move2 in move2utils package, I also wrote some functions to address the GPS outlier problem. The preprint is out and you can find it here: www.biorxiv.org/content/10.6...

Self-thresholding hierarchical outlier-detection for animal movement tracks

1). Erroneous locations are ubiquitous in animal tracking data and prove notoriously difficult to remove, particularly so in an unsupervised manner. Whether caused by poor satellite geometry, atmosphe...

An ICE agent in Houston shot and killed Lorenzo Salgado Araujo last week, the latest in a string of shootings by ICE officers who later claimed the victim attempted to hit them with a car—a claim that, in many cases, has been refuted by video evidence. minnesotareformer.com/2026/07/13/i...

Together, this points to a hierarchical strategy: memory picks the general area, and social information helps refine and maintain it. By establishing the mechanisms by which gannets occupy space, this framework can robustly predict responses under climate and offshore wind farm scenarios. 4/5

🚨Very happy to share our new paper out in @currentbiology.bsky.social! 🦉 We show that barn owl colour morphs do not simply experience moonlight differently — they hunt differently under it. White morphs appear to turn bright moonlight into a hunting advantage. 1/3 #movementecology #barnowl #moon

I'm recruiting a master's student for Fall 2026 to join my lab at The University of Arizona, to work on a project investigating the population genomics and hybridization dynamics of native and invasive leopard frogs in central Arizona! 🐸 🧬 Ad with details is posted below.

Abstract submission deadline getting closer (May 1, anywhere on Earth). Excited by all of the submissions received thus far, and excited to learn about all of the amazing research being done in statistical ecology. Look forward to seeing you all in Mérida, México!

Call for abstracts is now open for the next International Statistical Ecology Conference (ISEC) taking place on January 8-15, 2027, in Mérida, México! Abstract submission form can be accessed through the website: statisticalecology.org Deadline: May 1, 2026 (anywhere on earth) 🦋🇲🇽📉👩🏽‍💻

🚨New preprint and our results are rather concerning.. We find the "boiling frog" equivalent of AI use. Using large-scale RCTs, we provide *casual* evidence that AI assistance reduces persistence and hurts independent performance. And these effects emerge after just 10–15 minutes of AI use! 1/
