Populations of the silvereye, a small passerine bird, show several measures of genetic diversity that vary with island size in the Solomon islands. This mirrors the commonly-seen relationship between island size and taxonomic diversity.

New preprint using neutral models instead of randomised null-models for analysis of species distribution patterns (#nestedness, #segregation).
Might also interest #coalescence, island #biogeography, bird people.
Has a quick-start tutorial.
This cheerful Pygmy Mammoth is really happy that's it's #fossilfriday. #MammothSite #islandbiogeography (this specimen was excavated from Santa Rosa in 1994 by Larry Agenbroad, then dir of Mammoth Site).
Great to see our new paper out in the Journal of Biogeography!
We found that island characteristics and competitor density/presence impacts bird foraging traits in an island chain of the Indonesian Archipelago, showing the eco/evo processes at

This paper emerged from a great collaboration between Halu Oleo University in Kendari and Trinity College Dublin, dating back to 1999
I'm inspired by the #SkyIslands of southern Arizona and northern Sonora. They're literally islands, and a giant laboratory for the study of evolution. The hashtag is in my profile so it's about time I wrote about them! Looking forward to more, and hoping to get directly involved in research somehow. Maybe I can be a volunteer bug collector?

Fantastic new paper on the phylogeography of Solomon Island blossom bats (Melonycteris and Nesonycteris) by Lavery et al: https://onlinelibrary.wiley.com/doi/10.1111/jbi.14585?af=R
Walked to the grocer earlier and listened to one of my current reads.

I really enjoy Wikipedia's daily "Featured Article". Today's is about a cute extinct bird known (tho barely) only from a remote island east of Madagascar.
Does anyone else enjoy Wikipedia's featured articles?
