Community gradients of Arctic macrolichens in relation to succession, grazing and the environment

Creator:

Holt, Emily A.

Abstract:

The purpose of this dissertation was to define macrolichen community gradients in relation to succession, grazing and the environment. First, species scores indicating when macrolichen species appeared following disturbance were derived from the literature. Weighted averaging of these data with a community matrix created a successional score for each sample...

A method for remotely monitoring glaciers with regional application to the Pacific Northwest

Creator:

Medley, Brooke

Abstract:

An integrative method for monitoring glacier geometry change and mass balance is presented and applied to the Pacific Northwest, USA. Acting as a baseline for interpretation of future changes in glacier size and shape, we first derive a new inventory of regional glacier cover using remotely sensed data. To investigate...

Central place foraging and the winter village: a settlement pattern analysis in the lower Salmon River Canyon in Idaho

Creator:

Carlisle, Kendra

Abstract:

Hunter-gatherers depend on naturally occurring resources and, in order to survive, must overcome resource procurement challenges inherent in their environment. One challenge relates to the temporal and spatial availability of resources, which hunter-gatherers address, in part, through the strategic use of space to position themselves for optimal access to necessary...
