William DiMichele –– This paper describes a conflict between fossil macroflora and palynoflora in a dryland deposit of Pennsylvanian age (within the Late Paleozoic Ice Age). It interprets the dominance of wetland plants during this interglacial interval of seasonally dry climate as an indication of survival of wetland elements in refugia between periods of extensive wetland development during humid climate intervals. With increasing recognition that the glacial-interglacial periodicity of the "Coal Age" was accompanied by climate oscillations, the question has arisen of what happened to the wetland floras during times when equatorial latitudes were seasonally dry. The present paper provides strong evidence for the persistence of fragmented wetland vegetation within the lowland tropics during these drier intervals of glacial-interglacial cycles.
A large-scale field study examining effects of exposure to clothianidin seed-treated canola on honey bee colony health, development, and overwintering success

Dezene Huber –– There is a great deal of current discussion and debate over the role that pesticides - particularly neonicotinoids - may play in pollinator declines. Scientists, policy makers, and the general public are understandably concerned. This field-based study adds new and interesting data to the discussion and has the potential to influence decisions related to regulatory policy.
