Recent vegetation changes in central Queensland, Australia: Evidence from delta C-13 and C-14 analyses of soil organic matter
This study examines whether changes from grassy to woody vegetation coincide with the initiation of European farming practices (last 50-150 years) in central Queensland, using a site where historical records suggest invasion of woody vegetation (Acacia sp.). Soil samples were taken along a transect, spanning the transition between C4-dominated grassland and C3-dominated woodland. We utilize δ13C and 14C data of bulk and size-separated soil organic matter (SOM) to infer the time course of...[Show more]
