(UPI) New research suggests brood-tending bumble bee workers sleep much less than other bees, even forgoing sleep to care for offspring that is not their own. But unlike other animals, bees seem to do just fine without the normal amount of sleep.
(WSBT) In Michigan, tens of thousands of hives could be impacted. Even if bees don’t fly around at night time, that doesn’t mean the pesticide won’t impact their colony. “We don’t have a good sense on how much can be drawn into the hives, because the bees do create airflow in the colonies at night. And we don’t know how much will be deposited on the flowers that the bees will visit the next day.”
(The Conversation) To many people, power line corridors are eyesores that alter wild lands. But ecologically they are swaths of open, scrubby landscapes under transmission lines that support a rich and complex menagerie of life. New England researchers have surveyed bee communities in these corridors, finding numerous native species – including one of which is so rare it was thought to have been lost decades ago from the United States.
(University of British Columbia) Species have few good options when it comes to surviving climate change; they can genetically adapt to new conditions, shift their ranges, or both. But new research indicates that conflicts between species as they adapt and shift ranges could lead experts to underestimate extinctions, and underscores the importance of landscape connectivity. “The good news is this conflict between moving and adapting is reduced when movement rates are high, which emphasizes the importance of maintaining well-connected landscapes.”
(Washington University in St. Louis) Faced with unprecedented change in their environments, animals and plants are scrambling to catch up — with mixed results. Researchers have developed a new model that helps to predict the types of changes that could drive a given species to extinction. This model could give wildlife managers and conservation organizations insight into the potential vulnerabilities of different species based on relatively simple assessments of their natural histories and historical environments.
(Mexico News Daily) Beekeepers in Tizimín, Yucatán, have once again reported a massive die-off of bees and like last year, it appears that crop dusting is to blame. Three apiarists who work in the Yohactún de Hidalgo area told the newspaper Milenio that the bees in at least 50% of their hives have been killed.
(Bloomberg Environment) The European Union plans to tighten the criteria it uses to assess how harmful pesticides may be to honey bees, potentially making it harder for manufacturers to get authorized for some of their products. The tighter criteria would become mandatory when evaluating how pesticides affect bees in the short-term, under a draft rule the European Parliament’s environment committee discussed Sept. 25.
(Omaha World-Herald) The official Nebraska state insect is feeling the sting of agricultural chemicals, unfavorable weather, flooding and mites, according to beekeepers big and small.
