Honeybees, Apis mellifera, have several prophylactic disease defense strategies, including the foraging of antibiotic, antifungal, and antiviral compounds of plant products. Hence, honey and pollen contain many compounds that prevent fungal and bacterial growth and inhibit viral replication. Since these compounds are also fed to the larvae by nurse bees, they play a central role for colony health inside the hive. Here, we show that honeybee nurse bees, infected with the microsporidian gut parasite Nosema ceranae, show different preferences for various types of honeys in a simultaneous choice test. Infected workers preferred honeys with a higher antibiotic activity that reduced the microsporidian infection after the consumption of the honey. Since nurse bees feed not only the larvae but also other colony members, this behavior might be a highly adaptive form of therapeutic medication at both the individual and the colony level. 相似文献

Initiatives for reducing anthropogenic greenhouse gas emissions from deforestation and degradation require transparent and
robust methodologies for the estimation of emissions reduction or removal. Although carbon (C) stock change in degradation
and devegetation by remote sensing are becoming increasingly powerful, the drivers of degradation, wood collection and harvest
dynamics, cannot be understood without “on the ground” sampling. A methodological tool for the quantitative and qualitative
analysis of forest degradation is proposed as developed based on a research on the stump history in the black locust degrading
stands sampled in southwest Romania. Based on the survey of stumps, the cutting regime and wood extraction is determined over
a past period of some 15 years. Stump age classification comprises multiple qualitative criteria (i.e. bark features; adherence
of sprouts; cut edge features; etc.). The method allows for a quantitative assessment of wood removal over time, and is suitable
for the development of a dynamic baseline and monitoring of degradation avoidance activities. 相似文献
