Human Disturbances Effects on Chlorophyll-A

Concerns over environmental disturbance in the McMurdo Dry Valleys are increasing with increasing foot traffic from tourists and scientist. The effect of pedestrian disturbance was monitored by comparing the species composition, depth distribution and soil properties between adjacent high-, low- and no- traffic sites. This study began in the austral summer 1995/1996.

Soil Biotic Effects Experiment (BEE) in Taylor Valley, Antarctica from 1999 to present

Increases in soil temperature and moisture may change the bioavailability of essential elements by altering solubility and diffusion rates in soils, or by changing the amounts of organic compounds. Long-term experiments in the Bonney, Hoare and Fryxell basins have been established with 3 treatments: 1) increased moisture, 2) soil warming (ITEX chambers), and 3) soil warming + increased moisture. The identification and abundance of soil biota are reported.
