The highlands (the area above 800 m) are dominated by alpine vegetation, bordered by boreal forest and wetlands at lower elevations, and have been described as southern mountainous outliers for the High Subarctic Tundra ecoregion (Meades, 1990). Complex changes in plant communities across a subarc...
whatever your hiking interests are. Your experienced guide will teach you about the local geology, biology and cultural history as you explore the alpine tundra. The options are almost limitless and wherever you decide to go, the alpine environment will provide a uniquely Alaskan alpine experience....
In the alpine tundra zone of Niwot Ridge, Colorado Front Range, U.S.A., both plant community and pocket gopher (Thomomys talpoides) distributions are, in large part, winter snowpack dependent. As a result it has proved possible to map the spatial variability in soil disturbance produced by ...
Aims: We posit that long-term monitoring of permanently marked plots provides data for making predictions of the impact of climate change on alpine tundra communities. Methods: We surveyed plant community composition and cover at four sampling time points over a forty-year span (1971-2011). ...
(D) Photograph of the arctic tundra Full size image The High Arctic site is located in northern Greenland at the Villum Research Station (VRS, 81° 36’ N, 16° 40’ W, 24 m a.s.l.; Fig. 1). Minimum and maximum soil temperatures at 5 cm soil depth were − 16.3 and 19.0 ...
We sampled a distinct and well-defined landscape unit within the GLV that is bound on the east by the tundra, on the south by alpine lakes, glaciers and meadows, on the west by the continental divide and on the north by steep cliffs. There is a large cliff face in the centre of our...
A basic map and details of the Alpine Loop can be downloaded on theBLM website here. We also recommend the use of aDeLorme Colorado Atlas & Gazetteer as a paper backup. Map by David Medeiros SPECIAL NOTE Throughout the journey you will encounter alpine tundra. Despite warning signs, it is...
a treeline instead of the existing alpine meadow or Arctic tundra. Meteorological data from the Italian Alps, United States Rocky Mountains, and Western Canadian Taiga-Tundra are used as forcing for model computation of ecosystem work and temperature gradients at sites on both sides of each ...
Endolithic Cyanobacteria may also contribute to silica dissolu- tion through alkalinization (Mapelli et al., 2012). Interestingly, a red surface patina can be observed on Miage debris, whose lithology shows general similarities with the one described by Borin et al. (2010), but is less ...
