Effects of climate warming on carbon fluxes in grasslands— A global meta-analysis
Climate warming will affect terrestrial ecosystems in many ways, and warming-induced changes in terrestrial carbon (C) cycling could accelerate or slow future warming. So far, warming experiments have shown a wide range ...
Predicting how seed-eating passerines respond to cattle grazing in a semi-arid grassland using seed preferences and diet
(Elsevier Science, 2020-02)
Numerical responses of animals to habitat perturbation often seem inconsistent, spreading skepticism about the predictive capacity of applied ecology. Domestic grazing changes several habitat variables that can affect ...
Changes in soil moisture predict soil carbon losses upon rewetting in a perennial semiarid steppe in SE Spain
(Elsevier Science, 2017-02-01)
Our understanding of the spatial and temporal dynamics of soil CO2 pulses after rainfall events is still limited and thus, our capacity to predict the consequences of future changes in precipitation patterns for dryland ...
Implantación de pasturas de pasto llorón y agropiro alargado en zona semiárida
(2014-12)
Consideraciones resultantes del trabajo de Experimentación Adaptativa en Explotaciones delos Partidos de Bahía Blanca y Coronel Rosales (Período 2008-2014).
Soil respiration in Patagonian semiarid grasslands under contrasting environmental and use conditions
(Academic Press Ltd - Elsevier Science Ltd, 2015-08)
Grasslands comprise 85% of Southern Patagonia land area and play a critical role in the global carbon cycle. We evaluated seasonal dynamics to identify differences in soil respiration rates between contrasting grasslands ...
Dwarf shrub facilitates seedling recruitment and plant diversity in semiarid grasslands
(Public Library of Science, 2019-02)
The facilitation mechanism maintains ecosystem richness by increasing seedling recruitment. Overgrazed grasslands of northwestern Patagonia are invaded by shrubs that could promote the seedling recruitment of forage species. ...
Effect of cattle breeding on habitat use of Pampas deer Ozotoceros bezoarticus celer in semiarid grasslands of San Luis, Argentina
(Academic Press Ltd - Elsevier Science Ltd, 2011-08)
The largest population of the Argentinean Pampas deer Ozotoceros bezoarticus celer is found in the semiarid grasslands of the San Luis province. Despite relatively high deer numbers in the region, there has been concern ...
