Are Patagonia grasslands being overgrazed? A response to Marino et al. (2020)
(Wiley, 2020-09)Based upon primary productivity estimates, Oliva et al. (2019) concluded that, at the end of last century and after long periods of overgrazing, Patagonia's domestic stocks adjusted to regional‐scale herbivore carrying ... -
Changes in forest structure values along the natural cycle and different management strategies in Nothofagus antarctica forests
(Elsevier, 2021-04-15)Ecologically sustainable forest management aims to preserve ecosystem integrity by providing wood and non-wood values. For this, it is necessary to determine the losses produced by the different management practices in ... -
Desarrollo de un modelo para asignación variable de carga animal (MAVC) en Patagonia Sur
(Fundación CIPAV, 2016-11)El ajuste de la carga animal es un aspecto clave en el manejo del pastoreo extensivo y en Santa Cruz, Argentina se realiza tradicionalmente utilizando una asignación fija de forraje (AFF) por animal, indistintamente si un ... -
Environmental Conditions and Grazing Exerted Effects on Arbuscular Mycorrhizal in Plants at Southern Patagonia Rangelands
(Elsevier, 2022-03)Arbuscular mycorrhizal (AM) fungi play a major role in maintaining ecosystem functions. AM fungi are found in most ecosystems including rangelands currently under increasing pressures from human activities. Southern Patagonia ... -
Holistic versus continuous grazing in Patagonia: A station-scale case study of plant and animal production
(Elsevier, 2021-01)We compared animal and vegetation responses of a 13 600-ha area under holistic grazing management (HGM) with a similar area under continuous grazing (CGM) in a Patagonian station. Limitations were a dry 2012 −2016 experimental ... -
Invasions: the trail behind, the path ahead, and a test of a disturbing idea
(Wiley, 2012-01)We provide a brief overview of progress in our understanding of introduced plant species. Three main conclusions emerge from our review: (i) Many lines of research, including the search for traits that make species good ... -
Landscape heterogeneity influences on sheep habits under extensive grazing management in Southern Patagonia
(2015)In Southern Patagonia, continuous grazing with fixed stocking rates in large paddocks prevails over grazing systems subjected to regular evaluations and rotational rests. Because of this, sheep extensive systems need ... -
Modeling soil nitrogen content in South Patagonia across a climate gradient, vegetation type, and grazing
(MDPI, 2019-05)Soil total nitrogen (N) stock in rangelands, shrublands, and forests support key ecological functions such as the capacity of the land to sustain plant and animal productivity and ecosystem services. The objective of this ... -
Modelling soil carbon content in south Patagonia and evaluating changes according to climate, vegetation, desertification and grazing
(2018)In Southern Patagonia, a long-term monitoring network has been established to assess bio-indicators as an early warning of environmental changes due to climate change and human activities. Soil organic carbon (SOC) content ... -
Nutrient availability controls the impact of mammalian herbivores on soil carbon and nitrogen pools in grasslands
(Wiley, 2020-02)Grasslands are subject to considerable alteration due to human activities globally, including widespread changes in populations and composition of large mammalian herbivores and elevated supply of nutrients. Grassland soils ... -
Pastoreo estratégico de ambientes para mejorar la producción ovina en campos del ecotono Bosque-Estepa en Patagonia Sur = Strategic grazing management for better sheep production at the forest-grass steppe ecotone in southern Patagonia
(Asociación Argentina de Producción Animal, 2014-06)El manejo del pastoreo en sistemas ganaderos extensivos con múltiples ambientes se presenta como un desafío dadas las condiciones climáticas y la configuración de los ambientes en los grandes potreros (300-5000 ha) propios ... -
Soil microbial communities respond to an environmental gradient of grazing intensity in south Patagonia Argentina
(Elsevier, 2020)Soil microorganisms communities regulate key functions in terrestrial ecosystems and contributes to the formation of stable organic matter and hence climate change mitigation. The structure, diversity and activity of soil ... -
Soil respiration in Patagonian semiarid grasslands under contrasting environmental and use conditions
(Elsevier, 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 ... -
Variation of grazing‐induced vegetation changes across a large‐scale productivity gradient
(Wiley, 2014-01)Questions: Does the magnitude of grazing‐induced changes in species composition vary with habitat productivity? How does the sign and magnitude of grazing effects on species richness and beta‐diversity change with increasing ...
