Air passing upward through the tropical tropopause is “marked” by an annually varying water vapor mixing ratio much as a tape recorder marks a magnetic tape; as the air ascends in the tropical stratosphere, these marks are effaced by a combination of vertical diffusion within the tropics and dilution of...
Computer science courses typically incorporate integrated training in software engineering, which includes learning how to reuse existing code libraries in new programs. This commonly presents a need to use the libraries’ application programming interfaces (APIs) during project-based learning activities. The students learn these APIs with little support from the instructor....
We compared the abundance, diversity, and composition of truffles in riparian and upland areas within a
mixed-conifer forest of the Sierra Nevada of California. We sampled for truffles in a single watershed over two seasons
(spring and summer) and 4 years to determine whether truffles were more abundant and diverse...
Swiss needle cast (SNC) is a fungal disease of Douglas-fir
(Pseudotsuga menziesii) that has recently become prevalent
in coastal areas of the Pacific Northwest. We used growth
measurements and stable isotopes of carbon and oxygen in
tree-rings of Douglas-fir and a non-susceptible reference
species (western hemlock, Tsuga heterophylla) to evaluate...
Objective: To translate a behavioral weight loss intervention for mid-life, low-income women in real world settings.
Design and Methods: In this pragmatic clinical trial, we randomly selected six North Carolina county health departments and trained their current staff to deliver a 16-session evidence-based behavioral weight loss intervention (special intervention, SI)....
We sought to improve net ecosystem exchange (NEE) estimates for a tall, dense, mature Douglas-Fir forest in the Oregon Coast range characterized by weak flows, systematic wind directional shear, and limited turbulent mixing throughout the diurnal period. We used eddy covariance (EC) observations at two levels and concurrent biological measurements...
In this paper we consider the total space of the canonical bundle of P² and we use a proposal by Hosono, together with results of Seidel and Auroux–Katzarkov–Orlov, to deduce the physical mirror equivalence between D[superscript b][subscript P²] (K[subscript P²]) and the derived Fukaya category of its mirror which assigns...
The process of plant speciation often involves the evolution of divergent ecotypes in
response to differences in soil water availability between habitats. While the same set of traits
is frequently associated with xeric/mesic ecotype divergence, it is unknown whether those
traits evolve independently or if they evolve in tandem as...
The effect of disturbance on the resistant propagule community (RPC) of ectomycorrhizal
fungi has been given relatively little attention. In this study we investigate the effects of
heat, one important factor of fire disturbances, on the ability of ectomycorrhizal RPC fungi
to colonize Pinus jeffreyi seedlings in greenhouse bioassays. Prior...
