An ancient delta complex is partly recorded by the upper seven
formations of the Cretaceous Nanaimo Group exposed on Mayne and
Samuel Islands of southwestern British Columbia. Features especially
suggestive of deltaic sedimentation here are: upward-coarsening
marine to fluvial sequences, cyclic repetition of facies, subaqueous
slumping, fluvial-marine interfingering, facies changes,...

Premise of research. A new, morphologically distinct, anatomically preserved conifer assignable to the basal Cupressaceae, which was subject to arthropod infestation during life, has been discovered within a marine carbonate concretion from the Coniacian (Late Cretaceous) Eden Main locality of Vancouver Island, British Columbia. Methods. Specimens were studied from anatomical...
Bacteria in the diverse Pseudomonas fluorescens group include
rhizosphere inhabitants known for their antifungal
metabolite production and biological control of plant disease,
such as Pseudomonas protegens Pf-5, and mushroom
pathogens, such as Pseudomonas tolaasii. Here, we report
that strain Pf-5 causes brown, sunken lesions on peeled
caps of the button...
Fusarium crown rot (FCR), caused by and , reduces wheat ( L.) yields in the Pacific Northwest (PNW) of the US by as much as 35%. Resistance to FCR has not yet been discovered in currently grown PNW wheat cultivars. Several significant quantitative trait loci (QTL) for FCR resistance have...
The Greenhorn Mountains contain a tectonic ally disrupted
ophiolite and both arc-derived and pelagic sediments. Age of major
sedimentary units within and bordering the thesis area is Early
Permian, based upon dates of conodonts and fusulinids from contemporaneous
but allocthanous limestones. Sediments near the south
boundary of the thesis area...

There has been much discussion in the conservation and policy realms of COVID-19 as a zoonotic disease, or a disease transmitted from wildlife to humans. However, wildlife consumption in China is not only a potential source of disease but also a practice embedded in complex beliefs about health. This paper...
