| 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. |
