Impacts of Quaternary Climate History on the Biogeography of Specialized Butterflies in the Great Basin of North America

Journal of Biogeography, Volume 53, Issue 8, August 2026.
ABSTRACT Aim Dramatic Quaternary climate fluctuations impacted the evolutionary history and contemporary biogeography of many residents of the Great Basin Desert of western North America. This study investigates the historical biogeographic processes that shaped the contemporary distribution of genetic variation in a polytypic group of specialized ...

Pollinator efficiency, rather than bee decline, explains a shift to hummingbird pollination in tropical montane forests

New Phytologist, Volume 251, Issue 4, Page 2237-2247, August 2026.
Hummingbird pollination is a hallmark of American plant diversity and has long been thought to evolve in tropical mountains due to declining bee activity. Using sister species of Costus specialized on bees (C. kuntzei) and hummingbirds (C. wilsonii), we show that this shift is not driven by reduced bee visitation with elevation, but by greater ...
