Feeding patterns by roe deer and rabbits on pine, willow and birch in relation to spatial arrangement

Article Abstract:

The hypothesis that selection of the same food plants by two herbivore species with different body mass, roe deer and rabbits, is affected by the spatial disposition of preferred plants in relation to less preferred ones is tested. The results indicate that the location and association of trees could strongly affect foraging patterns of roe deer, but not in a manner wholly consistent with the repellent-plant or the attracted-decoy hypotheses.

Winter browsing on Alaska feltleaf willow twigs improves leaf nutritional value for snowshoe hares in summer

Article Abstract:

Winter browsing helps in the reduction of competition among meristems for mineral nutrients, competition for nitrogen and the shoot carbohydrate reserves. The effects of winter browsing on snowshoe hare nutrition at the time of reproduction on the hare population dynamics are discussed.

The influence of larval density, food availability and habitat longevity on the life history and population growth rate of the midge Chironomus riparius

Article Abstract:

The density dependent responses under controlled conditions of an important indicator species, Chironomus riparius, are investigated. Slow growth of some chironomid larvae help in its survival from reduction in response availability.
