Insecticides damage bee socialization and learning skills, study reports

ScienceDaily Wikimedia Commons Researchers find that bees fed with thiacloprid  (a neonic) significantly reduces their social interactions,  suggesting that foraging bees that encounter  high  doses of insecticide in the field may be less likely  to recruit others to nectar sources.  Story here.

The cycle of mercury pollution in the Arctic tundra

Nature Human activity has been a major source of mercury pollution in  the Arctic, and a new  study   has identified the form most often  taken by the pollutant: gaseous elemental  mercury  (GEM). The  present  News & Views  article discusses how the Arctic tundra  acts as a major sink for mercury, as the local plants uptake GEM  from  the atmosphere; and  what this means for the global mercury  cycle as  global temperatures warm. Isotopic data  collected in the  original study  by Obrist  et al.  reveal that GEM accounts for 90% of  the  mercury in plants,  and the uptake of GEM by plants is  especially  high in the summer. Since  plant matter decomposes  into the soil,  the Arctic soil may soon become  a substantial  mercury sink. ======== Editor's summary Anthropogenic activities have led to large-scale mercury pollution in the Arctic, but it remains uncertain whether wet deposition of oxidized mercury via precipitation and sea-salt-induced ch
