Abstract:
Changes in biodiversity due to human impact of domestic grazers are occurring in many parts of the world, and the net effect of this change could have detrimental effects on ecosystem functioning. The selective removal of palatable grass species results in localized species loss from areas subject to heaving grazing, which may have consequences for carbon and nitrogen cycling. Moreover, in areas where shrub encroachment is not occurring, the changes due to human impact within functional groups may be very important. We explored the relative importance of dominant grass species in a water-limited ecosystem in the Patagonian steppe of temperate South America. Dominant grass species from the Patagonian steppe in southern Argentina were collected and used in a manipulative decomposition experiment to examine the role of these species, which vary in palatability, in affecting decomposition and nutrient turnover. All litter types were decomposed singly and in all possible mixtures (7) over a three-year period and effects of litter quality as well as location next to the three grass species were evaluated. These data were collected as part of the project CRN 012 examining the effects of biodiversity on ecosystem functioning, led by Dr. Osvaldo Sala.
