Ecology: The Experimental Analysis of Distribution and Abundance
TLDR
This book discusses ecosystem dynamics under Changing Climates, which includes community dynamics at the community level, and factors that limit Distributions, which limit the amount of variation in population size. Expand
Impact of Food and Predation on the Snowshoe Hare Cycle
TLDR
Food and predation together had a more than additive effect, which suggests that a three-trophic-level interaction generates hare cycles. Expand
Population Fluctuations in Rodents
Expansion of Canopy-Forming Willows Over the Twentieth Century on Herschel Island, Yukon Territory, Canada
TLDR
Evidence of increases of each of the dominant canopy-forming willow species, including Salix richardsonii, Salix glauca and Salix pulchra, during the twentieth century is found, indicating expansion in canopy cover and height on Herschel Island. Expand

TLDR
60 years of research that has uncovered many of the causes of these population cycles are reviewed, areas of controversy that remain and key questions to address are suggested to address. Expand
What Drives the 10-year Cycle of Snowshoe Hares?
TLDR
The spectacular cycles of snowshoe hares and their predators have captured the attention of biologists as well as historians, and the challenge to biologists has been to understand the mechanisms behind these cycles, which has not been easy. Expand
Population Cycles Revisited
TLDR
Progress in analyzing cyclic fluctuations has been made most rapidly when people define clear alternative hypotheses and carry out experimental manipulations on field populations, and much remains to be done on these small mammals. Expand
The sensitive hare: sublethal effects of predator stress on reproduction in snowshoe hares.
TLDR
This is the first study in a free-ranging population of mammals to show that elevated, predator-induced, glucocorticoid concentrations in individual dams caused a decline in their reproductive output measured both by number and quality of offspring. Expand
