Data Identification

Abstract: Vegetation was quantified using point frame (top and bottom hits only), above ground biomass can be estimated based on the lifeform-specific algorithms. Warming treatments are performed using hexagonal OTCs (left year round).
Purpose: The International Tundra Experiment is a collaborative effort involving scientists from more than 11 countries, including all the Arctic nations. ITEX seeks to examine the response of circumpolar cold adapted plant species and tundra ecosytems to environmental change, specifically to an increase in summer temperature. Empirical knowledge based on experiments coupled with available evolutionary history, ecology, and genetics was chosen as the best way to predict species response to climate change. The ITEX research model combines long-term and short-term experimentation with monitoring and has the elegance and simplicity called for to understand ecosystem response and vulnerability to change. The experiment is designed to examine the effects of temperature change; maximize geographic representation, by minimizing technical and equipment requirements; be long-term; focus primarily on species; and, if resources permit, allow for genetic and system level studies. Participation may be at several levels of complexity and sophistication depending on interests and available funding support. Each ITEX site operates some form of warming experiment. Most sites use open-top chambers to warm the tundra. These passive chambers affect plant growth and phenological development in a variety of ways. Each ITEX study site is expected to collect similar data following established protocols provided in the ITEX Manual. Collectively the ITEX network is able to pool its data sets to examine vegetation response at varying levels, for example genetics (from ecotype to functional type), across space (from habitats to ecosystems) and over time.
