Spatial climate datasets of 1981–2010 long-term mean monthly average dew point and minimum and maximum vapor pressure deficit were developed for the conterminous United States at 30-arcsec (~800m) resolution. Interpolation of long-term averages (twelve monthly values per variable) was performed using PRISM (Parameter-elevation Relationships on Independent Slopes Model). Surface stations...
The dynamics of vorticity motions forced by wave groups incident on an
alongshore-uniform barred beach are analyzed. For both normally and obliquely incident
wave groups, the potential vorticity and enstrophy equations reveal that the temporal
variability of wave group–forced vortices is directly linked to the variability in the
incoming wave...
The rip current field resulting from the transformation of surface gravity waves over
offshore submarine canyons is studied. Employing a wave transformation model and a
wave-induced circulation model over observed bathymetry we find that wave height
variations associated with undulations in the canyon contours cause rip current circulation
cells with...
Greenhouse studies were conducted to evaluate the influence of selected adjuvants on
glyphosate efficacy on yellow nutsedge and tuber production. Glyphosate was applied
at 0, 0.25, 0.43, 0.87, 1.26 (1x rate), and 1.74 kg ae ha⁻¹ 31 d after yellow nutsedge
was planted. Each rate was mixed with one of...
In many regions of the world, the extremes of winter cold are a major determinant of the geographic distribution of perennial plant species and of their successful cultivation. In the United States, the U.S. Department of Agriculture (USDA) Plant Hardiness Zone Map (PHZM) is the primary reference for defining geospatial...
Premise of research: A distinctive new species of osmundaceous fern, based on a permineralized trunk from
Lower Cretaceous deposits of Haida Gwaii (formerly the Queen Charlotte Islands) off the west coast of mainland
Canada, provides additional data for addressing the Mesozoic diversity and the overall pattern of phylogeny
for osmundaceous...
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...
Background
Two major mycoparasitic lineages, the family Hypocreaceae and the genus Tolypocladium, exist within the fungal order, Hypocreales. Peptaibiotics are a group of secondary metabolites almost exclusively described from Trichoderma species of Hypocreaceae. Peptaibiotics are produced by nonribosomal peptide synthetases (NRPSs) and have antibiotic and antifungal activities. Tolypocladium species are...
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...
Genome-enabled mycology is a rapidly expanding field that is characterized by the pervasive use of genome-scale data and associated computational tools in all aspects of fungal biology. Genome-enabled mycology is integrative and often requires teams of researchers with diverse skills in organismal mycology, bioinformatics and molecular biology. This issue of...
