Spatial variability models of CO 2 emissions from soils colonized by grass ( Deschampsia antarctica ) and moss ( Sanionia uncinata ) in Admiralty Bay, King George Island
Abstract Soil CO 2 emission is an important part of the terrestrial carbon cycling and is influenced by several factors, such as type and distribution of vegetation. In this work we evaluated the spatial variability of soil CO 2 emission in terrestrial ecosystems of maritime Antarctica, under two co...
