Combination of herbivore removal and nitrogen deposition increases upland carbon storage
Smith, Stuart; Johnson, David; Quin LO, Samuel; Munro, Kyle; Pakeman, Robin J; van der Wal, René; Woodin, Sarah J. (Journal article; Peer reviewed, 2015)Ecosystem carbon (C) accrual and storage can be enhanced by removing large herbivores as well as by the fertilizing effect of atmospheric nitrogen (N) deposition. These drivers are unlikely to operate independently, yet ... -
Milling plant and soil material in plastic tubes over-estimates carbon and under-estimates nitrogen concentrations
Smith, Stuart; Robertson, A H Jean; Meharg, Andrew A; Pakeman, Robin J; Johnson, David; Woodin, Sarah J.; van der Wal, René (Journal article, 2013)Background and aims Milling of plant and soil material in plastic tubes, such as microcentrifuge tubes, over-estimates carbon (C) and under-estimates nitrogen (N) concentrations due to the introduction of polypropylene ... -
Optimizing carbon storage within a spatially heterogeneous upland grassland through sheep grazing management
Smith, Stuart; Vandenberghe, Charlotte; Hastings, Ashley; Johnson, David; Pakeman, Robin J; van der Wal, René; Woodin, Sarah J. (Journal article; Peer reviewed, 2014)Livestock grazing is known to influence carbon (C) storage in vegetation and soil. Yet, for grazing management to be used to optimize C storage, large scale investigations that take into account the typically heterogeneous ... -
Root traits predict decomposition across a landscape-scale grazing experiment
Smith, Stuart; Woodin, Sarah J.; Pakeman, Robin J; Johnson, David; van der Wal, René (Journal article; Peer reviewed, 2014)- Root litter is the dominant soil carbon and nutrient input in many ecosystems, yet few studies have considered how root decomposition is regulated at the landscape scale and how this is mediated by land‐use management ...
