We report here that (4R,9Z)-hexadec-9-en-4-olide [(R)-desmolactone] is a sex
attractant or sex pheromone for multiple species and subspecies in the cerambycid
genus Desmocerus. This compound was previously identified as a female-produced
sex attractant pheromone of Desmocerus californicus californicus.
Headspace volatiles from female Desmocerus aureipennis aureipennis contained
(R)-desmolactone, and the antennae...

We used microsatellite DNA data and genetic stock identification methods to delineate the temporal and spatial distributions of juvenile Chinook Salmon Oncorhynchus tshawytscha occupying coastal habitats extending from central Oregon to northern Washington. Juveniles were collected in trawl surveys conducted during spring, summer, and autumn over 15 years. Distributions (mean...

Because iso- and anisohydric species differ in stomatal regulation
of the rate and magnitude of fluctuations in shoot
water potential, they may be expected to show differences in
the plasticity of their shoot water relations components, but
explicit comparisons of this nature have rarely been made.
We subjected excised shoots...

The compositions and loadings of organic matter in soils and sediments from a diverse range of environments along the Fly River system were determined to investigate carbon transport and sequestration in this region. Soil horizons from highland sites representative of upland sources have organic carbon contents (%OC) that range from...

First-year tree seedlings represent a particularly vulnerable life stage and successful seedling establishment is crucial for forest
regeneration. We investigated the extent to which Pinus ponderosa P. & C. Lawson populations from different climate zones
exhibit differential expression of functional traits that may facilitate their establishment. Seeds from two populations...

To investigate the dynamics of the Atlantic meridional overturning circulation (AMOC) on
timescales longer than the observational records, model-data comparisons of past AMOC variability
are imperative. However, this remains challenging because of dissimilarities between different proxy-based
AMOC tracers and the difficulty of comparing these to model output. We present an...

Epidemiological evidence has demonstrated a reduced risk of prostate cancer associated with cruciferous vegetable intake. Follow-up studies have attributed this protective activity to the metabolic products of glucosinolates, a class of secondary metabolites produced by crucifers. The metabolic products of glucoraphanin and glucobrassicin, sulforaphane and indole-3-carbinol respectively, have been the...
