Here, we identified the gene locus associated to royal jelly production through whole-genome sequencing of the DNA from eight populations of honeybees. The analysis of the samples was composed of 120 individuals and each pointed extremely opposite trait values for a given phenotype. We identified ...
population genomics of honey bees reveals a selection signature indispensable for royal jelly production.[2020][mol cell probes]
In 2006, bees across the U.S. started dying rapidly. Now, the U.S. honey bee population is at an all-time high, according to the Census of Agriculture. Clay Bolt, manager of pollinator conservation for the World Wildlife Fund U.S., joins CBS News to explain what happened.May 14, 20...
The population diversity of Carniolan honey bee was analysed using mitochondrial DNA (mtDNA) with RFLPs as well as DNA microsatellites [15]. One mtDNA haplotype (COI-COII region) was detected in the samples of Slovenian and Croatian honey bees, indicating their genetic affiliation to the same ...
SummaryComputer simulation was used to investigate the efficacy of top crossing within closed breeding populations of honeybees. Top crossing is carried out by selecting a single breeder queen (top-cross parent) to contribute all or a significant proportion of the drones needed to inseminate the vi...
根据前文"The bee population is dropping sharply.In some areas,losses of honeybees are reported to be as high as 75 percent.(蜜蜂的数量正在急剧下降。据报道,在一些地区,蜜蜂的损失高达75%。) "可知,本段讲述的是蜜蜂数量下降的后果。选项"G.The situation means a lot more than high honey prices....
In some areas, losses of honeybees are reported to be as high as 75 percent.(蜜蜂的数量正在急剧下降。据报道,在一些地区,蜜蜂的损失高达75%)”可知,本句承接上文说明蜜蜂损失高导致的结果:蜂蜜价格高。故E选项“这种情况不仅仅意味着蜂蜜价格高”符合语境,故选E。 (2)题详解: 根据后文“If you ...
Epidemiology and Genomics of European Foulbrood (Melissococcus plutonius) of Honey Bees European Foulbrood (EFB) is an important disease of honey bee larvae that has increased in prevalence in recent years, in both the UK and other countries. EFB is caused by the gram-positive bacterium Melissoco...
It seemed as if thousands of honeybees were vanishing into thin air. There were no traces left behind and no dead bees were being found near the colonies. Since then, more than 30% (and for some unlucky beekeepers, up to 90%) of the honeybee colonies have been disappearing each year,...
HONEY, WHO SHRUNK THE BEE POPULATION? ; across America, Millions of Honey Bees Are Abandoning Their Hives and Flying off to Die, Leaving Beekeepers Facing Ruin and US Agriculture under Threat. and to Date, No One Knows Why. Michael McCarthy Reports ++ Species under Threat...
