The ascomycete fungus Tolypocladium inflatum, a pathogen of beetle larvae, is best known as the producer of the immunosuppressant drug cyclosporin. The draft genome of T. inflatum strain NRRL 8044 (ATCC 34921), the isolate from which cyclosporin was first isolated, is presented along with comparative analyses of the biosynthesis of...
Stressful environmental conditions affect the adrenocortical function of developing animals, which can have consequences
for their fitness. Discovery of the avian stress hormone corticosterone (CORT) in feathers has the potential to broaden the
application of endocrine research in ecological and evolutionary studies of wild birds by providing a long-term measure...
A study was conducted to identify geographical variation in loblolly pine bark and wood properties at the whole-tree level and to quantify the responses in whole-tree
bark and wood properties following contrasting silvicultural practices that included planting density, weed control, and fertilization. Trees were destructively sampled from
both conventionally managed...
Mixia osmundae (Basidiomycota, Pucciniomycotina) represents a monotypic class containing
an unusual fern pathogen with incompletely understood biology. We sequenced and analyzed
the genome of M. osmundae, focusing on genes that may provide some insight into its
mode of pathogenicity and reproductive biology.
Mixia osmundae has the smallest plant pathogenic basidiomycete...
We compared three existing ecoregional classification schemes (Bailey, Omernik, and World Wildlife Fund) with two derived schemes (Omernik Revised and Climate Zones) to explore their effectiveness in explaining species distributions and to better understand natural resource geography in the Klamath Region, USA. We analyzed presence/absence data derived from digital distribution...
We investigated intra-specific variation in the response of salmon to infection with the
myxozoan Ceratomyxa shasta by comparing the progress of parasite infection and measures of
host immune response in susceptible and resistant Chinook salmon Oncorhynchus tshawytscha at
days 12, 25 and 90 post exposure. There were no differences in...
We propose the Breathing Earth System Simulator (BESS), an upscaling approach to quantify global gross primary productivity and evapotranspiration using MODIS with a spatial resolution of 1-5 km and a temporal resolution of 8 days. This effort is novel because it is the first system that harmonizes and utilizes MODIS...
The potato psyllid, Bactericera cockerelli (Šulc), is
a vector of the bacterium ‘Candidatus Liberibacter
solanacearum’ (Lso) that has been linked to the economically
devastating zebra chip disease of potato. To date, four haplotypes
of the potato psyllid have been identified and include
Central, Western, Northwestern, and Southwestern haplotypes.
Zebra chip...
The putative methyltransferase LaeA is a global regulator that affects the expression of multiple secondary metabolite gene clusters in several fungi, and it can modify heterochromatin structure in Aspergillus nidulans. We have recently shown that the LaeA ortholog of Trichoderma reesei (LAE1), a fungus that is an industrial producer of...
Worldwide, in recent years capture fisheries targeting lower-trophic level forage fish and euphausiid crustaceans have been substantial (∼20 million metric tons [MT] annually). Landings of forage species are projected to increase in the future, and this harvest may affect marine ecosystems and predator-prey interactions by removal or redistribution of biomass...
