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...

Weintroduce two simple methods for the statistical comparison of the temporal pattern
of life-cycle events between two populations. The methods are based on a translation of stagefrequency
data into individual Ôtimes in stageÕ. For example, if the stage-k individuals in a set of samples
consist of three individuals counted at...
Reported here is an investigation to determine the in vitro and in vivo metabolism
of xanthohumol (XN). XN is the major prenylated flavonoid of the female
inflorescences (cones) of the hop plant (Humulus lupulus). It is also a constituent of
beer, the major dietary source of prenylated flavonoids. Recent studies...
What do you say when you have only a minute to explain to a municipal official why keeping track of the number of bird species found in a park may help make decisions about park management? Talk of significant differences among treatments or testing theory will likely meet with glazed...
We examined terrestrial amphibians in managed headwater forest stands in western Oregon from 1998 to 2009. We assessed: (1) temporal and spatial patterns of species capture rates, and movement patterns with distance from streams and forest management treatments of alternative riparian buffer widths and upland thinning; (2) species survival and...
RNA silencing is an evolutionarily conserved system that
functions as an antiviral mechanism in higher plants and
insects. To counteract RNA silencing, viruses express
silencing suppressors that interfere with both siRNA- and
microRNA-guided silencing pathways. We used comparative
in vitro and in vivo approaches to analyse the molecular
mechanism of...
