Bench scale column studies were used to examine the partitioning of microorganisms between groundwater
and a geologic medium and to examine the effect of hydrogeology (i.e., porous- versus fracture-flow) on
organism partitioning. Replicated columns were constructed with intact basalt core segments that contained
natural fractures and with the same basalt...
Consumer-grade GPS units are a staple of modern field ecology, but the relatively
large error radii reported by manufacturers (up to 10 m) ostensibly precludes their
utility in measuring fine-scale movement of small animals such as insects. Here
we demonstrate that for data collected at fine spatio-temporal scales, these devices...

We investigate the momentum balance in the surf zone, in a setting which is weakly varying in the alongshore direction. Our focus is on the role of nonlinear advective terms. Using numerical experiments, we find that advection tends to counteract alongshore variations in momentum flux, resulting in more uniform kinematics....
Little is known about the impact of temperature on proanthocyanidin (PA) accumulation in grape skins, despite its
significance in berry composition and wine quality. Field-grown grapes (cv. Merlot) were cooled during the day or
heated at night by +/–8 C, from fruit set to veraison in three seasons, to determine...
The current work sought to develop predictive
models between time-weighted average polycyclic aromatic
hydrocarbon (PAH) concentrations in the freely dissolved
phase and those present in resident aquatic organisms. We
deployed semipermeable membrane passive sampling devices
(SPMDs) and collected resident crayfish (Pacifastacus
leniusculus) at nine locations within and outside of the...

Cenococcum is a genus of ectomycorrhizal Ascomycota that has a broad host range and geographic distribution. It is not known to produce either meiotic or mitotic spores and is known to exist only in the form of hyphae, sclerotia and host-colonized ectomycorrhizal root tips. Due to its lack of sexual...
