They used along-term dataset of North American bumble bee species occurrences to determine whether the community temperature index (CTI), a measure of the balance of warm- and cool-adapted species ...

To learn this, the authors analyzed a long-term dataset of North American bumblebee species as their populations rose and fell in correlation with the community temperature index (CTI), a measure ...

Climate change is rapidly restructuring North American bumblebee communities, according to newly published research from the laboratory of Professor Neal Williams, a pollination ecologist in the UC ...

For comparison, North America has fewer than 500 mammal species. But what scientists know so far skews toward bigger species that are easier to observe and identify. Thousands of small bee species ...

The other species that disappeared from the lower 48 states is the variable cuckoo bumblebee, which is dependent on another struggling species, the American bumble bee, as its primary host.
