Reducing risks from E. coli 0157 on the organic farm
(Canadian Centre for Sustainable Agriculture, Saskatoon, Saskatchewan., 2001)
E.coli 0157 is a bacterial pathogen of the human intestinal tract which is carried in certain species of livestock and wildlife without ill effect. Such organisms are termed zoonotics. Various types of Campylobacter and ...
Systems for sustainable agriculture: approaches, tradeoffs and needs
(Canadian Centre for Sustainable Agriculture, Saskatoon, Saskatchewan, 2001)
All systems of agriculture practiced today can be seen as having a potential for improvement and contributing toward a more sustainable agriculture. The major differences in approach and in the types of services needed to ...
The dystroglycan complex is necessary for stabilization of acetylcholine receptor clusters at neuromuscular junctions and formation of the synaptic basement membrane
(2001-02)
The dystrophin-associated protein (DAP) complex spans the sarcolemmal membrane linking
the cytoskeleton to the basement membrane surrounding each myofiber. Defects in the DAP
complex have been linked previously to a ...
Analysis of animal movement using opportunistic individual identifications: Application to sperm whales
(2001-05)
Data sets in which animals are identified individually in different places and times may contain considerable information on movements. However, if the probability that an animal is reidentified depends on its movement ...
Strong bottom-up and top-down control of early life stages of macroalgae
(2001-06)
In contrast to most pelagic primary producers, benthic macrophytes pass through morphologically distinct life stages, which can be subject to different ecological controls. Using factorial field experiments, we investigated ...
Behavioral reactions of northern bottlenose whales (Hyperoodon ampullatus) to biopsy darting and tag attachment procedures
(2001-04)
The effects of invasive or intrusive research techniques need to be thoroughly documented in order to satisfy appropriate standards of animal care. How cetaceans react to either biopsy darting ol tag attachment procedures ...
Predicting wave dislodgment of mussels: variation in attachment strength with body size, habitat, and season
(2001)
Breaking waves impose large hydrodynamic forces which may dislodge mussels and other organisms
living on exposed rocky shores. We examined the effect of variation in attachment strength with
size, habitat and season on ...
Aggressive nest intrusions by male Humboldt Penguins
(2001-02)
During observations at a breeding colony of Humboldt Penguins (Spheniscus humboldti), we noted five male penguins enter nests occupied by breeding pairs and engage in aggressive interactions with the resident adult. These ...
Variation in egg spawning among subpopulations of sea urchins Strongylocentrotus droebachiensis: a theoretical approach
(2001)
Variation in zygote production, by determining the initial size of the larvalpool, can aff ect
the population dynamics of marine invertebrates with a planktonic larval stage. In this paper, we
model temporal and spatial ...
Interspecific and intraspecific variation in proximate, mineral, and fatty acid composition of milk in old world fruit bats (Chiroptera : Pteropodidae)
(2001-01)
We examine the effect of body mass on milk composition among Old World fruit bats, including
Pteropus pumilus (0.175 kg), Pteropus rodricensus (0.265 kg), Pteropus hypomelanus (0.571 kg), and
Pteropus vampyrus (1.133 ...
