Abstract:: Abstract: Coastal upwelling zones may be at enhanced risk from ocean acidification as upwelling brings low aragonite saturation state (Ω[subscript Ar]) waters to the surface that are further suppressed by anthropogenic CO₂. Ω[subscript Ar] was calculated with pH, pCO₂, and salinity-derived alkalinity time series data from autonomous pH and pCO₂...

Abstract:: Freshwater discharge affects the biogeochemistry of river-influenced nearshore environments by contributing with carbon and nutrients. An increase in human activities in river basins may alter the natural riverine nutrients and carbon export to coastal ecosystems. Along a wide latitudinal range (32° 55'S-40° 10'S), this study explores the role of climate...

Abstract:: The mating flight behavior of drone honey bees from swarm clusters is compared to drone mating flight behavior from colony situations. Duration of flight from swarms and colony situations is similar. Swarm drones appear to take as many flights/day but spend less time between flights than colony drones.

Abstract:: Male Apis mellifera L. (drones) accompanying reproductive swarms were analyzed for honey stomach contents to determine if they engorge honey prior to or during swarming. No evidence for engorgement was found. A diurnal feeding rhythm in drones was observed in non swarming colonies.

Abstract:: The previously suggested protection from microbial attack of ripening nectar by the addition of glucose oxidase by the common honey bee, Apis mellifera L., has been found to occur in 9 other eusocial Hymenoptera from 3 superfamilies. The antibacterial effect results from the accumulation of hydrogen peroxide produced by the...

Abstract:: The hepatotoxic alkaloids known to occur in tansy ragwort (Senecio jacobaea L.) are also present in honey produced from the nectar of this species. These alkaloids, which include senecionine, seneciphvlline, jacoline, jaconine, jacobine, and jacozine, are potentially carcinogenic, mutagenic and teratogenic and may pose health hazards to the human consumer.

Abstract:: An examination of a commercial honey-bee apiary for the Acarcapis species complex revealed the following: queens were essentially free from Acarapis parasitism: colonies were more frequently infested with A. dorsaiis and A. woodi than A. externus: individual worker-bee hosts were rarely parasitized by more than one Acarapis species. Observed sex...

Abstract:: As a result of the Chernobyl accident on April 25, 1986. possible radioactive contamination of honey bees and cheese sampled in several areas of the United States were measured. Of bees collected in May and June of 1986 in both Oregon and New York, only those from Oregon showed detectable...

Abstract:: A quantification of the number of adult worker Apis meltifera L. found on combs of standard sizes at full holding capacity is reported. Estimating the holding capacity of combs can assist in evaluating honey-bee colonies for pollination capabilities and also for honey-production potentials

Abstract:: Fluxes of sulphur dioxide to wheat were measured over two growing seasons. The deposition velocity, vg, depended primarily on affinities of surfaces for SO2 and varied from less than 0.1 to about 1.5cms−1. Stomata were an important sink, and diurnal changes in stomatal resistance accounted for most of the variation...
