Abstract

The Monsoon Rainfall Manipulation Experiment (MRME) is to understand changes in ecosystem structure and function of a semiarid grassland caused by increased precipitation variability, which alters the pulses of soil moisture that drive primary productivity, community composition, and ecosystem functioning. The overarching hypothesis being tested is that changes in event size and variability will alter grassland productivity, ecosystem processes, and plant community dynamics. In particular, we predict that many small events will increase soil CO2 effluxes by stimulating microbial processes but not plant growth, whereas a small number of large events will increase aboveground NPP and soil respiration by providing sufficient deep soil moisture to sustain plant growth for longer periods of time during the summer monsoon.

Comments

This dataset was originally published on the Long Term Ecological Research (LTER) Network Data Portal, https://portal.lternet.edu, and potentially via other repositories or portals as described. The Digital Object Identifier (DOI) of the source data package is doi:10.6073/pasta/f1af89711c4af25bfb290f116c633478, and may be accessed at http://dx.doi.org/10.6073/pasta/f1af89711c4af25bfb290f116c633478. Metadata and files included in this record mirror as closely as possible the source data and documentation, with the provenance metadata and quality report generated by the LTER portal reproduced here as '*-provenance.xml' and *-report.html' files, respectively.

Spatial coverage

Location: The Monsoon site is located within Five Points Black Grama, just to the north of the grassland drought plots. On August 4, 2009, a lightning-initiated fire began on the Sevilleta National Wildlife Refuge. The Monsoon site was entirely burned on this date, with all plots subjected to fire of comparable intensity.Vegetation: The Monsoon site is dominated by black grama (Bouteloua eriopoda). Other prevalent grasses include Sporobolus contractus, S. cryptandrus, S. flexuosus, Muhlenbergia arenicola, and Bouteloua gracilis, siteid: 35
