Bees

Caffeine is a widely occurring plant defense chemical that occurs in the nectar of some plants, e.g., coffee and citrus, where it may influence pollinator behavior to enhance pollination. New laboratory tests show that buff-tailed bumblebees (Bombus terrestris) locate new food sources emitting a learned floral odor more consistently if…

Some flowers use a clever strategy to ensure effective pollination by bees, doling out pollen gradually from two different sets…

Most flowering plants depend on pollinators such as bees to transfer pollen from the male anthers of one flower to the female stigma of another flower, enabling fertilization and the production of fruits and seeds. Bee pollination, however, involves an inherent conflict of interest, because bees are only interested in…

The European honeybee has been in Australia for almost 200 years and its presence is often seen as benign, even beneficial. But that may not always be the case.Key points:Feral European bees may outcompete native bees for floral resourcesScientists do not fully understand the impacts and say more research is…

If anyone knows about going fungal, it’s Paul Stamets. I have often wondered whether he has been infected with a fungus that fills him with mycological zeal—and an irrepressible urge to persuade humans that fungi are keen to partner with us in new and peculiar ways. I went to visit…
