How to protect bumblebee colonies safe from killer moths? Keep honeybee hives away from them

Researchers have shown for the first time that bumblebee colonies are more likely to become infested with bumblebee wax moths as they are closer to nearby honeybee hives, which can likewise host these potentially devastating parasites. As the distance to the apiaries decreased, bumblebee colonies were less productive, while their workers showed a weaker general immune response to pathogens and parasites. The authors advise honeybee keepers to keep apiaries away from habitats rich in bumblebees, which are important pollinators but declining worldwide.

Tadpoles try to flee dangerous virus in their pond by growing much faster than normal

Researchers from the US studied the plasticity in growth and development of wood frog larvae in response to the emerging disease ranavirus, which can kill off the entire population of ponds. They showed that tadpoles in infected ponds speed up the rate of growth and progression through the immature stages. They hypothesize that this plasticity boosts their physical condition and hence immune response to ranavirus, and allows them to metamorphose earlier and escape infection.

Drones could be the ‘magic tools’ we need to chase bears away from people

Starting in 2017, Wesley Sarmento was the first prairie-based bear manager at Montana Fish, Wildlife and Parks, a job that regularly put him right in between massive grizzly bears and people. He is also the author of a new Frontiers in Conservation Science article in which he describes the effectiveness of different methods that aimed to deter bears from human settlements, avoid conflicts between wildlife and locals, and help the successful conservation of the species. In the following guest editorial, he describes his seven-year-long search for the most effective hazing method.

Completing the timetree of primates: a new way to map the evolutionary history of life on Earth

In a new article published in Frontiers in Bioinformatics, biologists Dr Jack M Craig, Dr Blair Hedges, and Dr Sudhir Kumar, all at Temple University, have built an evolutionary tree that encompasses 455 primates, every species for which genetic data are available. The tree, the most complete of its kind, shows the evolutionary timescale of the whole order of primates, including monkeys, apes, lemurs, lorises, and galagos. In the following guest editorial, Dr Craig describes the steps of obtaining an almost complete timetree for primates and explains the value of such data.

Broken sleep a hallmark sign of living with this common liver disease, scientists find

Researchers from Switzerland have shown that patients with metabolic dysfunction-associated steatotic liver disease (MASLD) suffer poor sleep due to sleep fragmentation and wakefulness. Patients with the more severe form metabolic dysfunction–associated steatohepatitis (MASH) or with cirrhosis, but not healthy volunteers, experienced similar sleep disturbances. Whether poor sleep causes MASLD or vice versa isn’t yet clear. A single sleep hygiene education session proved insufficient to sustainably improve sleep quality and quantity.

Viking colonizers of Iceland and nearby Faroe Islands had very different origins, study finds

Geneticists have studied the distribution of Y-chromosome haplogroups on the Faroe Islands, known to have been colonized by Vikings around the year 900 CE, and compared these to distributions of haplogroups in today’s Scandinavia. They showed with novel analysis methods that the haplotype distribution in the Faroe Islands most closely resembled that in Norway and Denmark, and to a lesser extent that in Sweden, but differed from that in Iceland. They concluded that a band of Viking men from all over Scandinavia colonized the Faroe Islands, which differed in their geographical origin and genetic make-up from those who settled Iceland.
