Vegetation community, foliar nitrogen, and temperature effects on tundra CO₂ exchange across a soil moisture gradient / Jennifer Dagg, Peter Lafleur.
Title: | Vegetation community, foliar nitrogen, and temperature effects on tundra CO₂ exchange across a soil moisture gradient / Jennifer Dagg, Peter Lafleur. |
Author(s): | Dagg, Jennifer. Lafleur, Peter. |
Date: | 2011. |
In: | Arctic, Antarctic, and Alpine Research. (2011.), Vol. 43(2) (2011) |
Abstract: | Investigates CO₂ exchange in heterogeneous tundra landscape in Canadian Low Arctic with primary purpose of exploring relationship between moisture variability and community-level fluxes. Finds respiration and productivity to be highest in wet or mesic groups, with fewer differences in net CO₂ exchange. Across soil moisture gradient, productivity and net CO₂ exchange per leaf unit area and foliar nitrogen show significant negative linear trend. Respiration is limited in both very dry and saturated soil, and soil temperature effects on respiration are seen only in mesic moisture conditions. |
