Animal-Borne Acoustic Transceivers Reveal Patterns of at-Sea Associations in an Upper-Trophic Level Predator
(2012-11)
Satellite telemetry data have substantially increased our understanding of habitat use and
foraging behaviour of upper-trophic marine predators, but fall short of providing an understanding
of their social behaviour. We ...
Overestimating Fish Counts by Non-Instantaneous Visual Censuses: Consequences for Population and Community Descriptions
(2010-07)
Background: Increasingly, underwater visual censuses (UVC) are used to assess fish populations. Several studies have demonstrated the effectiveness of protected areas for increasing fish abundance or provided insight into ...
Unveiling Interactions among Mitochondria, Caspase-Like Proteases, and the Actin Cytoskeleton during Plant Programmed Cell Death (PCD)
(2013-03)
Aponogeton madagascariensis produces perforations over its leaf surface via programmed
cell death (PCD). PCD begins between longitudinal and transverse veins at the center of
spaces regarded as areoles, and continues ...
CBOL Protist Working Group: Barcoding Eukaryotic Richness beyond the Animal, Plant, and Fungal Kingdoms

A Meta-Analysis of Community Response Predictability to Anthropogenic Disturbances
(2012-09)
Disturbances often lead to changes in average values of community properties; however, disturbances can also affect the predictability of a community's response. We performed a meta-analysis to determine how response ...
A Meta-Analysis of Probiotic Efficacy for Gastrointestinal Diseases
(2012-04)
Background: Meta-analyses on the effects of probiotics on specific gastrointestinal diseases have generally shown positive effects on disease prevention and treatment; however, the relative efficacy of probiotic use for ...
Concurrent habitat and life history influences on effective/census population size ratios in stream-dwelling trout
(2012-03)
Lower effective sizes (Ne) than census sizes (N) are routinely documented in natural
populations, but knowledge of how multiple factors interact to lower N-e/N ratios is often limited.
We show how combined habitat and ...
The Ecology of Atlantic Cod (Gadus morhua) in Canadian Arctic Lakes
(2011-06)
The range of limnological conditions that support Atlantic cod populations in meromictic Arctic
lakes is known to be relatively restricted. The degree to which differences in these features,
particularly in the availability ...
The Influence of Operational Sex Ratio on the Intensity of Competition for Mates
(2011-02)
The evolution and maintenance of secondary sexual characteristics and behavior are heavily
influenced by the variance in mating success among individuals in a population. The operational sex
ratio (OSR) is often used as ...
What is a fish stock assessment? Is it a sound method? Can it be used to manage a commercial fishery?
(2015-09)
Under Karl Popper's non-inductive theory of method arguments are never carried from data to advice as in a fish stock assessment. That is: a distinction or 'demarcation' has to be made between (i) a Lamarckian-like inductive ...
