Phylogenetic analyses based on nLSU and ITS sequence data indicate that the sequestrate genus Gigasperma is polyphyletic. Gigasperma cryptica, which is known only from New Zealand, has affinities with the Cortinariaceae whereas G. americanum and two additional undescribed taxa from western North America are derived from Lepiota within the Agaricaceae....
Five Rambouillet x Polypay wethers (52 ± 2 kg BW; Experiment 1) and 5 Angus x Hereford steers (464 ± 26 kg BW; Experiment 2) were used in two incomplete 5 x 4 Latin squares with four 18-d periods to determine the influence of supplemental N source and supplementation frequency...
Various ocean-climate models driven by increased greenhouse gases and higher temperatures predict a decline in oceanic dissolved oxygen (DO) as a result of greater stratification, reduced ventilation below the thermocline, and decreased solubility at higher temperatures. Since spreading of low oxygen waters is underway and predicted to increase, understanding impacts...
The impact of population abundance on the deposit-
feeding rate of Mediomastus ambisetu (Capitellidae:
Polychaeta) was studied in still-water laboratory experiments.
Mean individual pellet production rate (mg worm¯¹ d¯¹) decreased
monotonically with increasing worm abundance in the
range of 6.5 X 10³ to 1.3 X 10⁵ worms m¯². Worms fed...
Impact bending and breaking radius were used to measure loss in toughness caused by basidiomycetes isolated from wood. Small test pieces were used to accelerate testing. Wide differences were found among, and sometimes within, the 26 species tested. Brown-rot fungi tended to cause greater losses than white-rot fungi, but no...
Assessing the impact of fungal decay in wood structures poses a major challenge for building inspectors. Although models have been developed to predict degradation rate of building components in varying climatic conditions, most are hampered by the lack of fundamental data on effects of fungal attack on engineering properties. Developing...
We present an in-depth case study of a learning network that aims to transform infrastructure and practice across the research enterprise to advance societal impacts. The theory of social morphogenesis guides our processual qualitative analysis of the network. We describe how different types of boundary work, both building and navigating...
OBJECTIVE: The 75% of older adults with multiple chronic conditions are at risk of therapeutic competition (i.e. treatment for
one condition may adversely affect a coexisting condition). The objective was to determine the prevalence of potential
therapeutic competition in community-living older adults.
METHODS: Cross-sectional descriptive study of a representative sample...
Rivers display temporal dependence in suspended sediment–water discharge relationships. Although most work has focused on multi-decadal trends, river sediment behavior often displays sub-decadal scale fluctuations that have received little attention. The objectives of this study were to identify inter-annual to decadal scale fluctuations in the suspended sediment–discharge relationship of a...
A global-scale three dimensional atmospheric transport and chemistry model was applied to simulate transpacific transport of Benzo[a]pyrene (BaP) emitted from Asia. The model results were compared with observations at six monitoring sites. The annual mean and seasonal variation of transport patterns and the contributions of different Asian source regions to...
