The populations of four species of North American bumblebee have declined, a new study has confirmed. The study also found that fungal infections are more likely to plague these bees than other ...

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 ...

There over 250 species of bumble bee worldwide — more than 40 of which are found in North America. However, many species have reportedly shown signs of decline across the country, with the ...

There are over 4,000 native North American garden bee species, in addition to the European honeybee, and many are in decline. Most native bees are solitary, individually nesting in tunnels rather ...

While most people picture the beloved honeybee when they think about bees, North America actually has 4,000 species of native bees, many of which are busy right now.

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 ...

Most bumble bees across North America — there are about 46 different species — emerge from their winter dormancy in the spring. They build up their nests, typically located in the ground.

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 ...
