Neonicotinoid pesticides cause harm to honeybees
June 24, 2016 04:38 PM - Johannes Gutenberg Universitaet Mainz via EurekAlert!

One possible cause of the alarming bee mortality we are witnessing is the use of the very active systemic insecticides called neonicotinoids. A previously unknown and harmful effect of neonicotinoids has been identified by researchers at the Mainz University Medical Center and Goethe University Frankfurt. They discovered that neonicotinoids in low and field-relevant concentrations reduce the concentration of acetylcholine in the royal jelly/larval food secreted by nurse bees. This signaling molecule is relevant for the development of the honeybee larvae. At higher doses, neonicotinoids also damage the so-called microchannels of the royal jelly gland in which acetylcholine is produced. The results of this research have been recently published in the eminent scientific journal PloS ONE.

California Condor Population Reaches New Heights

Karen Klein, Yale Environment 360

After years of intense — and often controversial — restoration efforts, biologists are finally reporting some good news for the beleaguered California condor: More chicks are surviving in the wild, and the birds are becoming increasingly independent and expanding their range.

Earlier this year, the U.S. Fish and Wildlife Service announced what it called a milestone for the California condor: More chicks had hatched and fledged in the wild during 2015 than the number of condors that had died. In late March, Steve Kirkland, the agency’s condor field coordinator, reported that two more chicks had fledged in 2015 in Baja California, but had only just been discovered, bringing the total in the wild to 270.

It was perhaps the most promising news about the condor in decades.
