Mechanisms Influencing the Timing and Success of Reproductive Migration in a Capital Breeding Semelparous Fish Species, the Sockeye Salmon
(University of Chicago Press, P.O. Box 37005 Chicago IL 60637 USA,
[mailto:help@press.uchicago.edu], [URL:http://www.journals.uchicago.edu/], 2009)
Two populations of homing sockeye salmon (Oncorhynchus nerka; Adams and Chilko) were intercepted
in the marine approaches around the northern and southern ends of Vancouver Island (British
Columbia, Canada) en route to ...
Population-specific gene expression responses to hybridization between farm and wild Atlantic salmon
(2009-11)
Because of intrinsic differences in their genetic architectures, wild populations invaded by
domesticated individuals could experience population-specific consequences following introgression
by genetic material of ...
Nonbreeding-Season Drivers of Population Dynamics in Seasonal Migrants: Conservation Parallels Across Taxa
(2009-12)
For seasonal migrants, logistical constraints have often limited conservation efforts to improving survival and reproduction during the breeding season only. Yet, mounting empirical evidence suggests that events occurring ...
Sex-specific, seasonal foraging tactics of adult grey seals (Halichoerus grypus) revealed by state-space analysis
(2009-11)
In many large pelagic animals, observing behavior is limited to observation by radio or satellite telemetry. In many cases, discriminating different behaviors from telemetry data has been a key, but often elusive, goal. ...
Avoidance of fisheries-induced evolution: management implications for catch selectivity and limit reference points
(2009-08)
I examined how the fitness (r) associated with early-and late-maturing genotypes varies with
fishing mortality (F) and age-/size-specific probability of capture. Life-history data on
Newfoundland's northern Atlantic cod ...
Temperature-mediated outbreak dynamics of the invasive bryozoan Membranipora membranacea in Nova Scotian kelp beds
(2009)
We used underwater videography to examine seasonal and interannual patterns in the cover (on
kelp) of the encrusting epiphytic bryozoan Membranipora membranacea, and associated changes in the
structure and abundance of ...
Intraguild interactions and large-scale population patterns
(2009-09)
Competitive interactions, including interference and intraguild predation, occur in many aquatic food webs and influence large-scale patterns of abundance, especially in lentic habitats. In a study of small coastal streams ...
Correlations among Fertility Components Can Maintain Mixed Mating in Plants
(2009-01)
Classical models studying the evolution of self-fertilization in plants conclude that only complete selfing and complete outcrossing are evolutionarily stable. In contrast with this prediction, 42% of seed-plant species ...
Herbivory and community organization on a subtidal cobble bed
(2009)
We examined the role of molluscan mesograzers (periwinkles Littorina littorea, limpets
Testudinalia testudinalis and chitons Ischnochiton ruber) in mediating macroalgal succession after a
mass mortality of sea urchins ...
Fatty acids tracers for native and invasive macroalgae in an experimental food web
(2009)
We assessed the potential of fatty acid (FA) markers for tracing primary production from an
invasive green alga (Codium fragile ssp. fragile) and a native kelp (Saccharina longicruris) through
2 trophic levels in an ...
