Quantitative information on the uptake and distribution of Al at the cellular level is required to understand mechanisms of Al toxicity, but direct measurement of uptake across the plasma membrane has remained elusive. We measured rates of Al transport across membranes in single cells of Chara...

Disentangling detoxification: Gene expression analysis of feeding mountain pine beetle illuminates molecular-level host chemical defense detoxification mechanisms

Bohlmann, Jörg, Bonnett, Tiffany R., Pitt, Caitlin, Keeling, Christopher I., Yuen, Macaire M. S., Huber, Dezene P. W., Robert, Jeanne A.
The mountain pine beetle, Dendroctonus ponderosae, is a native species of bark beetle (Coleoptera: Curculionidae) that caused unprecedented damage to the pine forests of British Columbia and other parts of western North America and is currently expanding its range into the boreal forests of...

Models that describe the spread of invading organisms often assume that the dispersal distances of propagules are normally distributed. In contrast, measured dispersal curves are typically leptokurtic, not normal. In this paper, we consider a class of models, integrodifference equations, that...

Dispersal, Population Growth, and the Allee Effect: Dynamics of the House Finch Invasion of Eastern North America
Download1996-01-01
Since about 1940, when they were first released in the new York City area, house finches (Carpodacus mexicanus) have multiplied explosively and colonized much of eastern North America. We take advantage of the richly detailed documentation of this biological invasion to construct a mathematical...

Disruption of a belowground mutualism alters interactions between plants and their floral visitors
Download2008-01-01
Cahill, J. F., Shore, B. H., Smith, G. R., Elle, E.
Plants engage in diverse and intimate interactions with unrelated taxa. For example, aboveground. oral visitors provide pollination services, while belowground arbuscular mycorrhizal fungi (AMF) enhance nutrient capture. Traditionally in ecology, these processes were studied in isolation,...

Distinguishing angiophytes from the earliest angiosperms: A Lower Cretaceous (Valanginian-Hauterivian) fruit-like reproductive structure
Download2009
A remarkably diverse Lower Cretaceous (Valanginian-Hauterivian) fl ora at Apple Bay, Vancouver Island, preserves seed plants at an important time of fl oristic evolutionary transition, about the same time as the earliest fl owering plant megafossils. The fossils are permineralized in carbonate...

Ecological systems are complex. All too often, complex models are fit to ecological data without consideration of whether parameters are estimable. I present a recent example for a parasite transmission model tracking the diffusion of sea lice from salmon farms in coastal British Columbia, fit...

Distribution and first reports of Branchiobdellida (Annelida: Clitellata) on crayfish in the prairie provinces of Canada
Download2009
Gelder, S. R., Williams, B. W., Proctor, H. C.
ABSTRACT.—Orconectes virilis (northern crayfish) were collected from 67 sites in Alberta, Saskatchewan, Manitoba, and far-western Ontario, Canada, and yielded 2 species of branchiobdellidans, Cambarincola vitreus and Cambarincola chirocephalus. This is the first report of branchiobdellidans in...
