Subalpine Forest Tree Seedling Response to Drought
… reduction shelters to mimic drought for subalpine conifer seedlings (<em>A. lasiocarpa</em> and <em>P. engelmannii</em>) in the Rocky Mountains and compared survivorship and morphological and physiological responses to assess relative degrees of drought tolerance. We detected no …

Behavioral Response to UVB Differs in Subalpine Populations of Daphnia Melanica
… <em>Daphnia melanica</em> that inhabit the subalpine ponds of the Olympic National Park are exposed to high levels of ultraviolet radiation (UVR). UVR causes DNA damage that can be detrimental to the organism if not fixed. One way to avoid these harmful rays is to migrate to protected areas. …

Vegetation-environment relationships in a subalpine wet meadow and a brackish tidal marsh
Community structure, community-environment relationships, the role of land surface elevation as a determinant of plant species composition, and aspects of scale were examined and compared between a brackish tidal marsh in the Squamish estuary and asubal pine wet meadow in Garibaldi Park in …

Succession of ectomycorrhizal fungi associated with Engelmann spruce and subalpine fir in Wyoming
Fungi associated with Engelmann spruce and subalpine fir were studied in a high altitude area of western Wyoming. Thirty permanent plots were established and their mean stand age determined. Three age classes were delineated: young (78 years), mature (127 years), and old-age (216 years). Stand and …

Topography, disturbance and climate: subalpine forest change 1972-2013, Rocky Mountain National Park, USA
… (Pearson and Dawson 2003). I resampled 68 subalpine forest plots originally surveyed in 1972-73 in Rocky Mountain National Park (RMNP) to investigate changes in species composition and structure and assess species migration during the past 40 years. I specifically considered forest change …

Evaluating subalpine lake delta carbon storage in the Colorado Front Range and Washington Central Cascades
… quantified. I sought to explore OC storage in subalpine lake deltas in the Washington Central Cascades and Colorado Front Range with the objectives of determining the magnitude of carbon storage and understanding the differences in storage between the two ranges. I used field, laboratory, and …

Assessing the threat of non-native salmonids to Lahontan cutthroat trout recovery in a subalpine watershed
Introductions of non-native fishes complicate native fish recovery and introductions of non-native salmonids have been implicated in the decline of inland cutthroat trout subspecies. The United States Fish and Wildlife Service has been restocking Lahontan cutthroat trout Oncorhynchus clarkii …

Limnological investigations of a natural, subalpine lake in the early stages of eutrophication: Mountain Lake, Giles County, Virginia
Comprehensive year-round limnological investigations of Mountain Lake, Virginia were conducted from November 1992 through October 1994. Monthly physical, chemical, and biological measurements suggest that this ecosystem has shifted toward a more eutrophic condition. A trend in whole lake mean …

Subalpine Cover Ecology of Eutamias amoenus, Eutamias townsendii and other small Mammals in Huckleberry Park, Mount Rainier National Park
… work has been done on the ecology of alpine and subalpine small mammals. They are included in faunal surveys, but little is known of their habits. In the summer of 1969 this study was undertaken in subalpine Huckleberry Park, Mount Rainier National Park, to determine the species of small mammals …

The Response of High Elevation Wetlands to Past Climate Change, and Implications for the Future
… at examining the response of mid-latitude subalpine fens to past climatic events potentially analogous to modern anthropogenic climate change was undertaken. As part of this research, a 4.18 m sediment core was retrieved from Harbison Pond (2651 m elev) near Grand Lake, CO and a 3.12 m peat …

Applying Wetland Rating Systems to Assess Functions of Depressional Wetlands Created by a Mass Wasting Feature, Table Mountain, Washington
… the Washington State Wetland Rating System in subalpine environments. Therefore, supplemental methods were used to enhance the quantification of ecological function. Results indicate high-elevation wetlands perform highest with regard to ecological function. In addition, elevation was found to …

Population Structure and Biophysical Density Correlates of Whitebark Pine (Pinus albicaulis) at Two Treelines in the Northern Rocky Mountains
… of treeline ecosystem dynamics; however, subalpine populations have declined nearly rangewide in recent decades. Though declines in subalpine forests have been well documented in the literature, few studies have assessed population structure and habitat requirements at treeline. Various …

The nature and significance of microtopographic effects on vegetation succession on selected glacier forelands, Jotunheimen and Jostedalen, Norway.
… findings refer to the major influences on subalpine and alpine vegetation patterns and include the following conclusions: a) Microtopographical effects are more complex than previously acknowledged. b) Exposure, snow-lie and fluvial activity are confounded and the relative importance of …
