Historic changes in Alpine Treeline Ecotone were modeled using 21 topographic, climatic, geologic, and disturbance variables in a random forest model. Airborne LiDAR and oblique historic repeat photography were used to identify changes in canopy cove

As forest cover in mountain areas impacts headwater properties like habitat extent and downstream water resources, it is important to assess and understand the changes that occur across forest transition zones like the alpine treeline ecotone (ATE).

Recent research emphasizes that female song is evolutionarily important, yet there are still few species for which we have quantified the similarities and differences between male and female song. Comparing song rates and the structure of female and

A field study revealed that some native intersectional hybrids of riparian poplars (Populus species) demonstrated faster growth than the parental species, and this was increased for female genets due to their greater clonal expansion. To investigate

Alpine Treeline Ecotone (ATE), the typically gradual transition zone between closed canopy forest and alpine tundra vegetation in mountain regions, displays an elevational range that is generally constrained by thermal deficits. At landscape scales,

Although decorticated rats are able to engage in play, their play is abnormal in three ways. First, decorticates do not display the normal, age-related shifts in defensive strategies during development. Second, decorticates do not modify their defens

Suites of correlated behaviors, or ‘‘behavioral syndromes,’’ have been shown to occur throughout the animal kingdom. Behavioral syndromes involving sexual selection are expected to have significant evolutionary ramifications, but few studies
