The crustose pyrenolichen Arthopyrenia betulicola is described as new to science based on collections from high elevations of Great Smoky Mountains National Park in eastern North America. The species is hypothesized to be endemic to the southern Appalachian Mountains where it occurs only on the bark of mature yellow birch (Betula alleghaniensis). It is a somewhat unusual member of the genus Art...

Rayleigh wave data between 20 and 120s period recorded in the western Ross Sea region of Antarctica are inverted using the waveform inversion technique described in Passier and Snieder [1995]. From the data we extract estimates of local S velocity structure beneath the Transantarctic Mountains and the Terror Rift. The shear wave velocities found are up to 6 % slower than the PREM model at betwe...

.b rom time to time the existence of typhus has been recorded in Kashmir. In the winter of 1942-43, an epidemic of typhus occurred in Kashmir, and this paper is based on a study of this epidemic. Kashmir is a large valley at about 5,500 feet surrounded by high mountains 12,000 feet high. In the main valley runs the Jhelum river and the tributaries of this river descend from smaller valleys lyin...

The objectives of this investigation were to evaluate the EO-1 Hyperion hyperspectral sensor for mapping forest composition and structure in rugged terrain and to compare its performance with that of AVIRIS and the Landsat 7 Enhanced Thematic Mapper Plus (ETM+). The study focused on species composition mapping with Hyperion, AVIRIS, and Landsat using a study site in the Green Ridge State Forest...

The Great Basin and Plateau encompass a vast region of western North America bracketed on the west by the Sierra Nevada and Cascade mountains and the east by the Rocky Mountains (Figure 1). The region is diverse but characterized by ecologically limiting, generally more arid conditions, and higher elevations than other parts of North America. It is also characterized by a type of archaeology th...

We describe Lachesilla texana Mockford and García Aldrete, n. sp., with populations in northeastern Mexico, central and southern Texas, and Great Smoky Mountains National Park, Tennessee. Several minor differences are noted between the Smoky Mountains and the Texas-Mexican populations. We assign the new species to the andra group (García Aldrete 1974) and in order to place it within this large ...

We use the contingent valuation method to measure the amount citizens are willing to pay to improve scenic mountain-view amenities through the removal of billboards. Our approach addresses both the perceived property rights as well as the perceptions of the status quo in the southern Appalachian Mountains. We find that individuals who retire to the mountains have different preferences for land ...
