An interesting study examined the interactions between coloration, island/mainland location, and predation in 12 species and 6 pairs of island/mainland locations. Dichromatic bird models suffered more apparent predation attempts on the mainland than on islands, and there was no difference for monochromatic bird models. Overall, predation attempts were lower on islands.

New study overturns long-held assumptions about how plants spread to #islands
A new study from #Iceland’s #Surtsey island shows that #birds carried most of the #plants that colonised the island, challenging long-held beliefs that seed or fruit shape determines how plants spread

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.

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
work in #biogeography

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

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?
