Nisbet, Roger, Anderson, Kurt E., McCauley, Edward, Lewis, Mark A.
Much ecological research involves identifying connections between abiotic forcing and population densities or distributions. We present theory that describes this relationship for populations in media with strong unidirectional flow (e.g., aquatic organisms in streams and rivers). Typically,...

Responses to n-3 fatty acid (LCPUFA) supplementation of gestating gilts, and lactating and weaned sows
Download2012
Smit, M. N., Patterson, Jennifer L., Spencer, Joel D., Dixon, Walter T., Dyck, Michael K., Foxcroft, George R., Cameron, Ashley C., Webel, Stephen K.
Feeding n-3 long-chain polyunsaturated fatty acids (LCPUFA) to gilts or sows has shown different responses to litter growth, pre-weaning mortality and subsequent reproductive performance of the sow. Two hypotheses were tested: (1) that feeding a marine oil-based supplement rich in protected n-3...

Rising from the ashes; an unanticipated failure with the engorgement factor voraxin leads to advances in three areas of tick biology: Developmental abnormalities and parthenogenesis, identification of a Coxiella-like symbiont and the molecular characterization of vitellogenesis in the southern African bont tick, Amblyomma hebraeum Koch (1844)
DownloadFall 2012
Weiss and Kaufman (2004, PNAS 101: 5874-5879) demonstrated that injections of fed male gonad homogenates stimulate engorgement in virgin female Amblyomma hebraeum ticks, due to the presence of the engorgement factor voraxin. They also showed voraxin's potential as part of an anti-tick vaccine:...

Seasonal phenology and reproductive behaviour of Dioryctria species Zeller (Lepidoptera: Pyralidae) in British Columbian seed orchards
DownloadSpring 2011
Seasonal phenology and mating frequency of moths in the genus Dioryctria found sympatrically in north Okanagan Valley, British Columbia seed orchards were assessed. Female moths in the abietella, auranticella, ponderosae and schuetzeella species groups were trapped in Douglas-fir, lodgepole pine...

Spatial ecology of cougars (Puma concolor) in the Cypress Hills: Implications for human-cougar interactions and range expansion
DownloadFall 2013
Cougar (Puma concolor) range is expanding eastward in North America. Understanding how range expansion is occurring in a human-dominated landscape is needed to manage the social and ecological implications of a returning large carnivore. To address this, I used GPS-radio collars and...

Early embryonic development is a dynamic period that requires precise and timely interaction between the developing embryo and the maternal environment. A series of studies were carried out in order to identify the vital components of this environment and to understand their temporal and spatial...

Testing for trade-offs between flight and reproduction in the mountain pine beetle (Coleoptera: Curculionidae) on two pine hosts
Download2019-01-01
Wijerathna, Asha, Whitehouse, Caroline, Proctor, Heather, Evenden, Maya
Mountain pine beetle, Dendroctonus ponderosae Hopkins (Coleoptera: Curculionidae: Scolytinae) adults fly to disperse before host colonization. The effect of flight on reproduction was tested by comparing the number and quality of offspring from beetles flown on flight mills to that of unflown...

One hundred and thirty-four pregnant beef cows (liveweight = 544.3 kg ± 73 3 kg SD; condition score = 3.5 ± 0.3 SD), were randomly assigned in January to five management treatments (combinations of feed restriction and weaning time) to study the effects on calving and rebreeding performance....

Fifty-four heifer calves were allocated to five feeding/weaning treatments at birth in April/May 1990: 1) VEW (n = 11) dams feed-restricted for 3 mo before and 2 mo after calving; calves weaned in June onto gram-supplemented pasture and then into a drylot in October; 2) EW1 (n = 10) dams not...
