Aridity and grazing as convergent selective forces: an experiment with an Arid Chaco bunchgrass
(Wiley, 2010-10)It has been proposed that aridity and grazing are convergent selective forces: each one selects for traits conferring resistance to both. However, this conceptual model has not yet been experimentally validated. The aim ... -
Effect of sowing rate and date on establishment and growth of Trichloris crinita, a native American pasture grass from arid environments, in the Arid Chaco of Argentina = Efecto de la densidad y fecha de siembra en el establecimiento y crecimiento de Trichloris crinita, una gramínea forrajera nativa de ambientes áridos de las Américas, en el Chaco Árido de Argentina
(International Center for Tropical Agriculture (CIAT), 2021-09)In arid regions, revegetation with locally adapted native species can improve forage production and help ameliorate soil degradation. We investigated the effects of 3 sowing dates and 3 sowing rates of Trichloris crinita ... -
Forage provision is more affected by droughts in arid and semi-arid than in mesic rangelands
(Wiley, 2022-06)Droughts are projected to increase in magnitude, frequency and duration in the near future. In rangelands, the provision of valuable ecosystem services such as forage supply for livestock productivity is intimately linked ... -
In search of sustainable livestock management in the Dry Chaco: effect of different shrub-removal practices on vegetation
(CSIRO, 2023)Increasing shrub density hinders cattle raising in central Argentina rangelands. While roller- chopping and hand-cutting are used to remove shrubs and make land accessible for cattle grazing, studies on the effects of these ...
