Boreas, EarlyView.Palynological records are central to the biostratigraphic subdivision of the Late Pleistocene in central Europe. Yet many interglacial and interstadial phases—such as the Eemian, Brörup and Odderade—remain only poorly constrained in time due to limited numerical dating.

The biology of mycorrhiza in the Ericaceae [PDF]
New Phytologist, 1989 SUMMARY Hymenoscyphus ericae utilizes protein as a sole source of nitrogen through the production of an extracellular proteinase. A sensitive procedure for assay of the enzyme is described and is used to determine the major characteristics of the enzyme. The enzyme has a sharp pH optimum at 2.2 with little activity above pH 5.0.

Journal of Applied Entomology, EarlyView.ABSTRACT Methyl salicylate (MeSA) is an herbivore‐induced plant volatile (HIPV) known to attract natural enemies of herbivores; however, its effectiveness as a semiochemical across diverse cropping systems and broad geographic regions remains unclear. In this 2‐year field study, we sampled natural enemies using MeSA‐baited and unbaited (control) yellow
