Sex Drives Intraspecific Scaling of Home Range Size in Mammals We GPS tracked 349 resident individuals across 18 mammal species to, for the first time, gain a broad understanding of how individuals' sex modulates home range scaling within species. Males showed a....

New article! Researchers GPS-tracked 349 individuals across 18 species. Result?
👉 Home range scaling is sex-driven — and we were missing it.

How does a single cuckoo species evolve eggs that mimic those of many different hosts?

In a new Science study, researchers report genomic data that reveal a complex geographic mosaic of cuckoo-host coevolution.

Genomic architecture of egg mimicry and its consequences for speciation in parasitic cuckoos Host-parasite arms races facilitate rapid evolution and can fuel speciation. Cuculus cuckoos are deceptive egg mimics that exhibit a broad diversity of counterfeit egg phenotypes, representing host-ad...

Our new @science.org paper is out! Cuckoos and hosts are locked in a coevolutionary arms race over egg mimicry.

But how are these egg types inherited, and could this drive speciation? We sequenced hundreds of genomes to find out!

How does genetic architecture constrain evolutionary trajectories? To address this question, we inferred the genetic architecture of convergent plumage coloration and its evolutionary history in wheatears.

The colour-marked Sanderling photographed in Israel, still carrying its radiotransmitter

A vagrant juvenile Sanderling turned up in Israel—likely after a single non-stop flight from the Dutch Wadden Sea. Here’s thread explaining why that’s remarkable and interesting. @wadertales.bsky.social @globalflyway.bsky.social #Birds #Migration

Animal niches in the airspace For flying animals, including many birds, bats, and insects, the air is a crucial arena for a range of behaviors. Technological advances, such as year-round tracking of flight altitudes and expanded u...

Are animals randomly distributed in the air, or is there a structure to where and when we find them? In our new paper we outline factors that shape habitat use in the air, from abiotic structure to biotic interactions. A lot of fun discussions behind this one! 🦅🦋🦇🌬
