Rodenticide exposure in wildlife in public and private wild lands: Our paper on owl exposure to rodenticides is just out! The work, led by Mourad Gabriel, shows that rodenticides are getting into the food chain in wild lands, and affecting top avian predators like the federally-listed Northern Spotted Owl and the Barred Owl. The source? Illegal marijuana grows. As the demand for marijuana grows with legalization, the supply has not kept up, and the black market in cannabis is present and growing - some of which is being carried out illegally on public and private wild lands.

The genome assemblies of the Northern Spotted Owl (Strix occidentalis caurina) are now online in Genome Biology and Evolution and PeerJ! Our first complete bird genome assembly, with mitochondrial assemblies (not trivial in this case!), and a great resource for Northern Spotted Owl conservation genetics! Way to go Zach Hanna (what an ambitious PhD project...!!!)
