The data and model described here with the purpose of understanding controls over biodiversity. A multi-scale approach to understand how local and regional factors affect the community assembly processes that drive emergent patterns.
This data package contains reflectance data and associated aerial images collected using a helicopter-suspended "albedo box," in which a shortwave radiometer and camera where mounted facing downward.
The McMurdo Dry Valleys, Antarctica, are experiencing rapid landscape scale change including increased glacial melt, the expansion of water tracks, thermokarst formation, an increase in the extent of the soil active layer, lake level rise, and altered stream flow. The impacts of these changes for biological communities are currently unknown. The goal of this study was to conduct surveys and experiments in three Dry Valley soil habitats that are expected to undergo change: water tracks, lake margins, and active layer profiles.
