Effects of fire and grazing in an arid grasslandecosystem

摘要: We examined short-term responses of grasses, shrubs, and rodents on experimental plots to determine how manipulations livestock grazing prescribed fire affect individual species community structure in a shrub-invaded arid grassland. Two grasses Gutierrezia sarothrae were found lower abundance burned the growing season after burned; all Prosopis glandulosa survived fire. Total rodent captures number Dipodomys spectabilis did not differ among treatments. No significant interaction between burning was observed. Fire seems have few negative effects this system.
