Title: Moose herbivory and carbon turnover of early successional stands in interior Alaska: Journal: Oikos; Authors: K. Kielland, J. P. Bryant, and R. W. Ruess; Date: 1997; Summary: Kielland et al. examined the effect of winter browsing by moose (Alces alces) and snowshoe hare (Lepus americanus) on primary succession of willow (Salix sp.) and alder (Alnus tenuifolia) communities in interior Alaska. In contrast to earlier studies, which have concluded that herbivory decreases organic matter turnover and element cycling in late successional evergreen forest, the authors show that herbivory increases these factors in the early successional forest, in which most browsing occurs.

Title: Nitrogen fertilization stimulates herbivory by snowshoe hares in the boreal forest: Journal: Canadian Journal of Zoology; Authors: V. O. Nams, N. F. G. Folkard, and J. N. M. Smith; Date: 1996; Summary: In the Yukon, a study of snowshoe hares, Lepus americanus, showed that they produced more pellets on plots with more fertilizer, than on plots with less fertilizer. Snowshoe hares also produced more pellets near plots with more fertilizer than near plots with less fertilizer. Also, fertilization increased the ratio of time spent on plots to time spent off of the plots. From the results, one could conclude that the change in pellet density reflects a change in hare movement rather than in defecation rate. Thus, the authors concluded that hares concentrated their activit ...; Agrovoc Control Words: Riparian zones, Rangelands, Wildlife; View more details about this article

Title: Herbaceous vegetation in the understory of the boreal forest: Does nutrient supply or snowshoe hare herbivory regulate species composition and abundance?: Journal: Journal of Ecology; Authors: E. John, and R. Turkington; Date: 1995; Summary: John and Turkington investigated the impact of nutrient addition and mammalian exclosures on the above-ground biomass and species composition of the understory vegetation of the boreal forest of southern Yukon in three field experiments. Experiment 1 was run from 1990-1992 during which time the major herbivore, the snowshoe hare (Lepus americanus), declined dramatically in numbers. It combined the addition of nutrients with the exclusion of herbivores in a 2 X 2 factorial design. Experiment 2 was run over an eight-week period in 1991, and tested the effects of exclosure ...; Agrovoc Control Words: Riparian zones, Rangelands, Wildlife; View more details about this article

Title: Feltleaf willow-snowshoe hare interactions: Plant carbon/nutrient balance and floodplain succession: Journal: Ecology; Authors: J. P. Bryant; Date: 1987; Summary: The effects of shading and fertilizer on the palatability, regrowth and phenolic concentrations of Salix alaxensis following simulated snowshoe hare browsing (Lepus americanus) were determined in this study. Simulated browsing reduced height, but enhanced twig growth, whereas shading reduced height and twig growth. Fertilizer and shade treatments reduced concentrations of phenolics and soluble carbohydrates in clipped plants, enhancing their palatability and reducing their ability to recover from browsing. The reduced height of browsed willows will most likely increase the shading of these ...; Agrovoc Control Words: Riparian zones, Rangelands, Wildlife; View more details about this article

Title: Interactions of snowshoe hare and feltleaf willow in Alaska: Journal: Ecology; Authors: J. P. Bryant, G. D. Wieland, T. Clausen, and P. Kuropat; Date: 1985; Summary: Severe snowshoe hare (Lepus americanus) browsing causes adult feltleaf willow (Salix alaxensis),in the Alaskan floodplain, to revert to the juvenile form for 2-3 years as a defense mechanism against further browsing. Results showed that snowshoe hares preferred twigs of adult shoots, rather than juveniles, formed after decapitation; chopping of juvenile twigs did not increase palatability. Nutritional quality and energy in juvenile sprouts were equal or higher than in adult form, but contained more ADF (acid-detergent fiber), and had higher concentrations of lignin and condensed tannins.
