Snowshoe Hare (lepus Americanus) and Mountain Cottontail (sylvilagus Nuttallii) Biogeography at Their Southern Range Limit
We surveyed snowshoe hare (Lepus americanus) and mountain cottontail (Sylvilagus nuttallii) in coniferous forests in northern New Mexico. L. americanus was restricted to the Sangre de Cristo and San Juan ranges in a narrow band of elevations corresponding to subalpine coniferous forest. In contrast, S. nuttallii was widely distributed and virtually cosmopolitan, occupying a wide range of elevat...
متن کاملAlteration of Sexual Reproduction and Genetic Diversity in the Kelp Species Laminaria digitata at the Southern Limit of Its Range
Adaptation to marginal habitats at species range-limits has often been associated with parthenogenetic reproduction in terrestrial animals and plants. Laboratory observations have shown that brown algae exhibit a high propensity for parthenogenesis by various mechanisms. The kelp Laminaria digitata is an important component of the ecosystem in Northern European rocky intertidal habitats. We stu...
متن کاملClimatic Sensitivity of a Mixed Forest Association of White Spruce and Trembling Aspen at Their Southern Range Limit
Climatic sensitivity of white spruce (Picea glauca (Moench) Voss) was examined growing in association with trembling aspen (Populus tremuloides Michx.) at their southern limit of distribution in a transitional ecotone between the southern boreal forest and northern prairie region. The study was carried out in the Spruce Woods Provincial Park (SWPP) located in southwestern Manitoba, Canada. The ...
متن کاملThe Probability of Moose Damage at the Stand Level in Southern Finland
The probability of moose damage was studied in sapling stands and young thinning stands in southern Finland. Data from the eighth National Forest Inventory in 1986–92 were used for modelling. The frequency of damage was highest at the height of two to fi ve meters and at the age of ten to twenty years (at the time of measurement). Moose preferred aspen stands the most and least preferred Norway...
متن کاملFine-Scale Genetic Structure of Bull Trout at the Southern Limit of Their Distribution
—We used six polymorphic microsatellite loci to analyze the population genetic structure of bull trout Salvelinus confluentus in the Boise River, Idaho, and we compared our results with previous data from similarly sized river systems in western North America. Within the Boise River, we found low genetic variation within and significant differentiation among sample sites. Two cohesive groups of...
