Record #195550:

Effects of fine-scale topography on CO₂ flux components of Alaskan coastal plain tundra: response to contrasting growing seasons / Paulo C. Olivas, and 5 others.

Title: Effects of fine-scale topography on CO₂ flux components of Alaskan coastal plain tundra: response to contrasting growing seasons / Paulo C. Olivas, and 5 others.
Author(s): Olivas, Paulo C.
Date: 2011.
In: Arctic, Antarctic, and Alpine Research. (2011.), Vol. 43(2) (2011)
Abstract: Evaluates CO₂ fluxes and moss contribution to ecosystem photosynthesis in response to fine-scale topography across drained lake bed in Barrow, Alaska, during two contrasting growing seasons. Assesses CO₂ exchange through static chamber measurements in three vegetation classes distinguished by plant dominance and topographic position within low-centred polygons. Under observed conditions, gross primary production (GPP) of polygon rim areas was significantly higher than GPP of vascular-dominated and intermediate areas. Also, ecosystem respiration of polygon rim areas was significantly higher than that of other microsites.
