Data from: Crown asymmetry in high latitude forests: disentangling the directional effects of tree competition and solar radiation
Light foraging by trees is a fundamental process shaping forest communities. In heterogeneous light environments this behavior is expressed as plasticity of tree growth and the development of structural asymmetries. We studied the relative influence of neighborhood structure and directional solar ra
Data from: Z chromosome divergence, polymorphism, and relative effective population size in a genus of lekking birds
Sex chromosomes contribute disproportionately to species boundaries as they diverge faster than autosomes and often have reduced diversity. Their hemizygous nature contributes to faster divergence and reduced diversity, as do some types of selection. In birds, other factors (mating system and bottle
The foraging behavior of <i>Ochotona princeps</i> (pika) and how tis correlates to certain aspects of the central foraging theory
The activity patterns of the long-legged bat, <i>Myotis volans</i> in conjunction with habitat
Missed opportunity cost for foraging in <i>Tamias minimus</i>, the least chipmunk, and <i>Spermophilus lateralus</i>, the golden-mantled ground squirrel
An investigation of the structure and location of escape burrows for the ground squirrel <i>Tamias minimus</i>
An intra- and inter-species investigation of burrow distances between <i>Spermophilus lateralis</i> and <i>Tamias minimus</i>
Behavioral responses to predation risk: survival strategies of the golden-mantled ground squirrel
Does predation effect abundance and diversity of zooplankton in beaver ponds?
Queen-queen interactions in the ant species <i>Formica neorufibarbis</i>
Interspecific and intraspecific interactions of two coexisting montane ground squirrel species (<i>Spermophilus lateralis</i> and <i>Tamias minimus</i>)

Seasonal movement patterns in a subalpine population of the tiger salamander, <i>Ambystoma tigrinum nebulosum</i>
Seasonal movements of a subalpine population of metamorphic tiger salamanders, Ambystoma tigrinum nebulosum, were explored from 1990 to 1992. Metamorphic adults bred in permanent and semipermanent habitats during June of each year. After breeding, soma individuals returned to the terrestrial environ
Reproductive success of colonial and noncolonial female yellow-bellied marmots
Survival of dispersing and philopatric yellow-bellied marmots: what is the cost of dispersal?
Understanding the evolution of dispersal has been hindered by a lack of reliable measures of the cost of dispersal. We report that survival of dispersing yellow-bellied marmots (Marmota flaviventris) (0.73) was only 16% less than survival of philopatric marmots (0.87). A cost-benefit analysis reveal
Diet alters metabolic rate in the yellow-bellied marmot during hibernation.
Resting and field metabolic rates of adult male yellow-bellied marmots, Marmota flaviventris
Total RMR and field metabolic rate of wild-caught males were estimated from oxygen consumption and the doubly-labeled water method and neither total RMR nor specific FMR were significantly related to time.
Home-range size and exploratory excursions of adult, male yellow-bellied marmots
Home-range sizes of adult, male yellow-bellied marmots (Marmota flaviventris) were estimated from radiotelemetry, trapping, and visual observation. Home ranges were monitored from early May to late August in 1989, 1990, and 1991. Home-range size varied greatly among males (range, 0.06–47.51 ha). Med
