An abundant fruiting of a black morel was encountered in temperate northwestern New South Wales (NSW), Australia, during a mycological survey in Sep 2010. The site was west of the Great Dividing Range in a young, dry sclerophyll forest dominated by Eucalyptus and Callitris north of Coonabarabran in an area...
Rhizopogon subgenus Villosuli are the only
members of the genus known to form an ectomycorrhizal
relationship exclusively with Pseudotsuga. The
specificity of this host relationship is unusual in that
Rhizopogon is broadly associated with several tree
genera within the Pinaceae and relationships with a
host genus are typically distributed across...
Six species of Cystangium, a genus of
sequestrate taxa related to Russula, were collected
in Patagonia (Argentina and Chile) during autumn
2001. Two species, C. depauperatum Singer & A.H.
Sm. and C. nothofagi (E. Horak) Trappe, Castellano &
T. Lebel, were already known from this region, while
four new species,...
Epichloë typhina, a fungal endophyte of
cool season grasses, is heterothallic and an obligate
out-crosser. In areas of endemism, its spermatia are
moved between stromata of the two opposite mating
types through egg-laying activities of Botanophila flies.
In western Oregon, where the fungus was inadvertently
introduced into seed-production fields of...
Simulations from a regional climate model (RCM) as part of a superensemble experiment were compared with observations of surface meteorological variables over the western United States. The RCM is the Hadley Centre Regional Climate Model, version 3, with improved physics parameterizations (HadRM3P) run at 25-km resolution and nested within the...
Collaborative fisheries research provides a mechanism for integrating the unique knowledge, experience, and skills of fishermen and scientists. It is a joint intellectual endeavor that begins with the inception of a project and continues until its final stages, with each group having mutual investment in-and ownership of-the project. Collaborative fisheries...
In the Sierra Nevada, distributions of forest tree
species are largely controlled by the soil-moisture
balance. Changes in temperature or precipitation as
a result of increased greenhouse gas concentrations
could lead to changes in species distributions. In
addition, climatic change could increase the frequency
and severity of wildfires. We used...

Computing resources donated by volunteers have generated the first superensemble of regional climate model results, in which the Hadley Centre Regional Model, version 3P (HadRM3P), and Hadley Centre Atmosphere Model, version 3P (HadAM3P), were implemented for the western United States at 25-km resolution. Over 136,000 valid and complete 1-yr runs...
This is the second part of a modeling study of wind-forced flow on the continental shelf off northern California in the region (37°-40°N) of the Coastal Ocean Dynamics Experiment (CODE). Gan and Allen [2002] analyzed the shelf flow response to idealized wind stress forcing in a process-oriented study. The study...
