Factors Influencing Mountain Pine Beetle (Coleoptera: Curculionidae: Scolytinae) Dispersal by Flight and Subsequent Trade-off Between Beetle Flight and Reproduction
DownloadFall 2016
The mountain pine beetle, Dendroctonus ponderosae Hopkins (Coleoptera: Curculionidae: Scolytinae), has an obligatory dispersal phase before selection of a suitable host for brood production. Flight during the dispersal phase is affected by both beetle physiology and environmental factors....

Local and regional demography in a migratory forest songbird and effects of forest management intensity
DownloadSpring 2014
The numerical response of forest birds to habitat alteration has been well documented in North America, but the underlying demographic processes driving these changes remain largely unknown. Among species sensitive to such alterations, the Ovenbird (Seiurus aurocapilla) shows one of the largest...

Population-level responses of fathead minnow (Pimephales promelas) to alarm substances and predator odour
DownloadSpring 2010
Alarm substances, released by injured prey, and odours from predators, such as northern pike, are chemical cues associated with increased predation risk in aquatic ecosystems. In laboratory studies, individual prey can respond to the presence of such cues by reducing conspicuous behaviours, such...

Resources and Reproductive Trade-offs Affect Fitness, Life History Traits, and Sexual Selection in Red Squirrels
DownloadSpring 2017
Animals face trade-offs throughout life between competing functions, such as between self-maintenance, reproduction, and survival. Resource allocation between these competing functions leads to different patterns of life history traits, changes in investment in reproductive effort, and different...

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...

The effects of defoliation on growth, reproduction and pollination of a non-native legume (Astragalus cicer) in the mixedgrass prairie
DownloadSpring 2017
Herbivory can lead to trade-offs between plant growth and reproduction as defoliated plants lose initial resource investments and have reduced photosynthetic capacity. This trade-off can lead to reduced investment into reproductive structures and have repercussions for floral traits, pollinator...
