In the early 1980’s, we began preparing separate spread wings to help illustrate features of birds that had never been accurately drawn.

Today our collection of spread wings is the largest in the world, preserving more than 40,000 specimens.

🚨 First PhD chapter is out! My work thus far, with @andy2dobson.bsky.social

We found that formerly common species have declined the fastest, on average.

North American bird declines are driven by reductions in common species
Declines in North American birds are driven not by rare species vanishing but by sharp losses among formerly common species.

Not to state the obvious, but some birds fly better than others. The ones that are awesome at flying -- this means they can get around obstacles, right? Expand their ranges as needed? Maybe be a little less vulnerable to extinction?

Turns out it's SUPER complicated.

New paper out in Ecology Letters (open access): I and Daniel Matute consider 'species sorting' -- a bias in the outcome of secondary contact following the allopatric stage of speciation -- as a reason for the much-observed pattern of elevated trait differences in sympatric close relatives
Secondary Sympatry as a Sorting Process
Early explanations for the frequent observation of exaggerated trait divergence in sympatric versus allopatric taxa focused on secondary contact between allopatrically speciating lineages and emphasi...

My first paper as a member of the Manthey lab is out in Biology Letters! We used whole genome data from a classic "great speciator" (the Solomon Island White-eyes) to explore the relationship between island size and genetic diversity.

1. Today the NIH director issued a new directive slashing overhead rates to 15%.

I want to provide some context on what that means and why it matters.
