First, we analyze annual USDA estimates of colony numbers at the aggregate (United States) level, as well as at the state level, to determine whether the managed honey bee population has been affected by the onset of CCD. Next, ... R. Rucker,W. Thurman 被引量: 1发表: 2011年 Five Wa...

Global bee population decline: A summary of the literatureFormentin, G. E.Air Quality & Climate Change
These species, by eventually killing the other insects, act as biological control agents that reduce the population levels of their hosts. Such control agents have many advantages: Parasitoids are often fairly host specific, and thus their effects are focused on the pest problem; a population of ...
Today, much of the world’s population never travels more than 50 or 60 miles from home. And even a person with abundant wealth and time can see only a fraction of the earth’s sights. But this new era of travel will cost so much less in both time and money that many more people ...
From cells in tissue, to bird flocks, to human crowds, living systems display a stunning variety of collective behaviors. Yet quantifying such phenomena first requires tracking a significant fraction of the group members in natural conditions, a substant
Viruses are omnipresent, yet the knowledge on drivers of viral prevalence in wild host populations is often limited. Biotic factors, such as sympatric managed host species, as well as abiotic factors, such as climatic variables, are likely to impact vira
Nucleus colonies of bees were established as previously described and relocated to a geographically isolated apiary and were grown to full-size colonies and equalized based on population prior to initiation of the study. The bees were maintained in eight-frame Langstroth equipment and kept as single...
Hives located in the natural area (henceforth natural hives or colonies) weighed the most (hive weight, Kruskal–Wallis test,p < 0.0001) (Fig.1a) yet had the smallest bee population (ANOVA test,p < 0.0001) (Fig.1d), excluding one colony with higher bee loads (i.e. outlier)....
United Nations reports throughout recent years have stressed the growing constraint of food supply for Earth's growing human population. Honey bees are a vital part of the food chain as the most important pollinator for a wide range of c... FE Murphy 被引量: 0发表: 2014年 To buzz or no...
