Species Diversity, Host Association, and Evolutionary History of Cronartium: An Important Global Fungal Pathogen to Trees. [PDF]
Ecol EvolWe determined that Cronartium probably occurred around 91.78 Ma during the Upper Cretaceous. Cronartium species may originated in Asia and North America and subsequently had several intercontinental dispersals via the North Atlantic Land Bridge, the De Geer Route, and the Bering Land Bridge. Additionally, we found that the diversification of Cronartium

Pollen Foraging by Bumble Bee Queens During a Critical Nesting Period Revealed by DNA Metabarcoding. [PDF]
Ecol EvolDuring the nest‐founding stage of the bumble bee (Apidae: Bombus) life cycle, solitary queen bees gather floral pollen to feed their offspring in nascent colonies. Here, in the first study of queen pollen loads in the southeastern U.S., we use next‐generation sequencing to characterize the pollen collected by wild bumble bee queens across northern and ...
