Red alder (Alnus rubra), a nitrogen(N)-fixing deciduous broadleaf tree, can strongly influence N
concentrations in western Oregon and Washington. We compiled a database of stream N and GIS-derived landscape
characteristics in order to examine geographic variation in N across the Oregon Coast Range. Basal area
of alder, expressed as a...
Spotted wing drosophila, Drosophila suzukii, is a devastating invasive pest of small and stone fruits in the Americas and Europe. To better understand the population dynamics of D. suzukii, we reviewed recent work on juvenile development, adult reproduction, and seasonal variation in life history parameters including the abiotic/biotic factors that...
