Journal ArticleDOI
Examination of interaction effects of multiple disturbances on an arid plant community
TL;DR: Fire and grazing seem to affect this arid plant community independently, with total abundance, species richness, and diversity of annuals being highest on plots subjected to both burning and grazing.
Journal ArticleDOI
Impact of exotic invasion on the temporal stability of natural annual plant communities
TL;DR: It is demonstrated that invasion by a dominant exotic species may reduce diversity without negatively affecting the temporal stability of natural communities, adding support to the idea that dominant species can strongly affect temporal stability, independent of community diversity.
Journal ArticleDOI
Long-Term Livestock Exclusion in an Arid Grassland Alters Vegetation and Soil
TL;DR: In this paper, the authors compared water-infiltration rates, soil bulk density, and perennial grass cover inside and outside a long-term livestock exclosure in an arid grassland site in southeastern Arizona, United States.
Journal ArticleDOI
Rodent granivory strengthens relationships between seed size and plant abundance in a desert annual community
Ting C. Chen,Thomas J. Valone +1 more
TL;DR: The hypothesis that rodent granivory affects the slope of the relationship between seed mass and plant abundance, causing it to become less negative when granivore pressure is reduced because rodents selectively harvest large seeds is evaluated.
