We observed a case of adoption of a single four-month-old polar bear cub (Ursus maritimus) into an existing litter of two cubs on Hopen Island, Svalbard. We believe the high density of maternity dens in the study area may increase the likelihood of natural adoption. Speculation about theoretical...

Adsorption of Biologically Critical Transition Elements to the Marine Cyanobacterium Synechococcus SP PCC 7002
Download2016-09-26
Bishop, Brendan A., Flynn, Shannon L., Robbins, Leslie J., Warchola, Tyler J., Owttrim, George W., Alessi, Daniel S., Konhauser, Kurt O.
It has been demonstrated that microbial biomass plays an important role in marine trace element cycling. The influence of microbes may be attributed to the dominantly negative surface charge of bacteria at pH values characteristic of seawater. Recent work has begun to more fully explore how...

Aftermath of mountain pine beetle outbreak in British Columbia: Stand dynamics, management response and ecosystem resilience
Download2016
Dhar, Amalesh, Parrott, Lael, & Hawkins, Christopher D. B.
The mountain pine beetle (Dendroctonus ponderosae Hopkins) (MPB) has infested and killed millions of hectares of lodgepole pine (Pinus contorta var. latifolia Engelm) forests in British Columbia, Canada, over the past decade. It is now spreading out of its native range into the Canadian boreal...

Age determination of a long-lived coregonid from the Canadian North: comparison of otoliths, fin rays and scales in inconnu (Stenodus leucichthys)
Download2004
Gendron, M., Tonn, W.M., Howland, K.L., Tallman, R.F.
We examined otoliths, pelvic fin rays and scales of inconnu to determine precision of age estimates within and between readers, and to compare relative accuracy of estimates from different structures. Our main objective was to determine if readability and estimates from fin rays and scales,...

Goodsman, Devin W., Koch, Daniel, Whitehouse, Caroline, Evenden, Maya L., Cooke, Barry J., Lewis, Mark A.
We investigate the inside dynamics of solutions to integrodifference equations to understand the genetic consequences of a population with nonoverlapping generations undergoing range expansion. To obtain the inside dynamics, we decompose the solution into neutral genetic components. The inside...

Al-Induced, 51-Kilodalton, Membrane-Bound Proteins Are Associated with Resistance to Al in a Segregating Population of Wheat
Download1997
Zhang, G., Good, A., Taylor, G. J., Slaski, J. J., Basu, A.
Incorporation of S-35 into protein is reduced by exposure to Al in wheat (Triticum aestivum), but the effects are genotype-specific. Exposure to 10 to 75 mu M Al had little effect on S-35 incorporation into total protein, nuclear and mitochondrial protein, microsomal protein, and cytosolic...

Models of population dynamics are a central piece for harvest management, allowing managers to evaluate alternative strategies and to identify uncertainty. Here we present a density-dependent population dynamics model that can be used in conjunction with adaptive management to optimize big game...

Potapov, A. B., Lewis, Mark A.
We consider the model of invasion prevention in a system of lakes that are connected via traffic of recreational boats. It is shown that, in presence of an Allee effect, the general optimal control problem can be reduced to a significantly simpler stationary optimization problem of optimal...

Krkošek, M., Ashander, J., Lewis, Mark A., Frazer, N.
The exchange of native pathogens between wild and domesticated animals can lead to novel disease threats to wildlife. However, the dynamics of wild host-parasite systems exposed to a reservoir of domesticated hosts are not well understood. A simple mathematical model reveals that the spill-back...
