ВЛИЯНИЕ НИЗОВЫХ ПОЖАРОВ НА ПЧЕЛ (HYMENOPTERA: APOIDEA) В ХИНГАНСКОМ ЗАПОВЕДНИКЕ, АМУРСКАЯ ОБЛАСТЬ
Обсуждается влияние весенних низовых растительных пожаров на фауну пчел на равнинных участках в Хинганском заповеднике. Предложены мероприятия по снижению частоты и силы пожаров в весенний период, основанные на наблюдениях за процессом снеготаяния ...

A subgeneric classification is proposed for Triepeolus—the second‐largest genus of cleptoparasitic apid bees in the world—and its sister genus Epeolus, with support from a newly presented dated phylogeny. Phylogenomic analysis based on ultraconserved elements revealed strong support for the monophyly of Triepeolus, which diverged from Epeolus sometime ...

Mixed effects of urbanization on pollination services among four native plant species
We tested urbanization and fragmentation effects on pollination services using four native phytometer species that were deployed across 10 community gardens located in suburban and densely urbanized areas Landscape context generally did not influence pollination; however, for one of four phytometers (Lobelia siphilitica, pictured above) urban cover ...

In Southern California, a global hotspot of bee biodiversity, predominantly feral populations of the exotic western honey bee constitute an estimated 90% of individual bees and 98% of bee biomass. Honey bee foragers remove 80% of total pollen during the first day flowers open on three common native species, with their first two visits removing over 60%

24 million years of pollination interaction between European linden flowers and bumble bees
Summary Pollination is the most common insect–plant mutualism, binding them in a co‐evolutionary framework. Historic evidence of this interaction can be partly inferred from time‐calibrated molecular phylogenies of plant and insect lineages or directly from fossils.
