Longitudinal and cross-sectional associations between physical activity, screen time, and fitness in a sample of young children from Edmonton, CanadaDownload
Background: High fitness is associated with several positive health outcomes; however, fitness of Canadian children has declined over the past two decades. Correlates of fitness in children under 10 years of age are relatively unexplored, and few studies involving young children have looked at...
The relationship between individual performance and nonrandom use of habitat is fundamental to ecology; however, empirical tests of this relationship remain limited, especially for higher orders of selection like that of the home range. We quantified the association between lifetime reproductive...
Modifiable cardiovascular disease (CVD) risk factors, such as adiposity, are already associated with atherosclerotic progression in childhood. Less is known about whether physical activity (PA) is associated with progression of atherosclerosis in non-clinical samples of children. This...
Linking occurrence and fitness to persistence: habitat-based approach for endangered greater sage-grouseDownload
Detailed empirical models predicting both species occurrence and fitness across a landscape are necessary to understand processes related to population persistence. Failure to consider both occurrence and fitness may result in incorrect assessments of habitat importance leading to inappropriate...
Resources and Reproductive Trade-offs Affect Fitness, Life History Traits, and Sexual Selection in Red SquirrelsDownload
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...
