This bee species may be endangered by climate change

This article discusses how certain types of bees may be endangered by climate change – a few degrees of warming make a big difference.

Across the western U.S., a shiny green bee pollinates manzanita shrubs and overwinters in the boreholes of trees.

But warming temperatures could make it harder for this species, Osmia ribifloris, to survive in parts of its native range.

Caradonna: “In already warm ecosystems like deserts, a lot of organisms may be close to their physiological limits. You warm up the temperature and they don’t really have a lot of room to adjust.”
