Anchored in 'average thinking' in studies of arid rangeland dynamics - The need for a step forward from traditional measures of variability
(2015-02)There is a wide consensus that arid and semi-arid environments are highly variable in space and time. The most frequent approaches to describe and analyze arid and semi-arid rangelands are based on the usage of averages ... -
Assessing the magnitude of impact of volcanic ash deposits on Merino wool production and fibre traits in the context of a drought in North-west Patagonia, Argentina
(CSIRO Publishing, 2014-02)Environmental variability is a key feature of arid and semiarid rangelands worldwide. Drought is one of the main sources of variation in most extensive livestock production systems in arid environments, with biophysical ... -
Características de las precipitaciones en zonas áridas de la Patagonia norte, Argentina
(Centro Universitario Rosario de Investigaciones Hidroambientales, Universidad Nacional de Rosario, 2022)La precipitación es determinante de múltiples procesos en zonas áridas. Abordar su variabilidad es difícil en áreas extensas y de baja densidad de registros como la Patagonia norte. El objetivo de este trabajo es caracterizar ... -
Ecosystem services and disservices associated with pastoral systems from Patagonia, Argentina –A review
(EDP Sciences, 2021-11-11)Pastoral systems worldwide secure rural livelihoods in the harshest environments on Earth. Their low productivity per area unit or head makes them the subject of much criticism with regard to their environmental impact, ... -
Evaluation of mohair quality in Angora goats from the Northern dry lands of Tajikistan
(2013-06)Mohair quality of Angora goats in the Sogd Province of Tajikistan was assessed in spring and autumn 2007 and 2008 by inspecting and sampling a total of 797 goats of both sexes, different ages and several coat colors from ... -
Evidence on the response of Patagonian forage grasses to the mulching effect of recent tephra deposits in Argentina
(Taylor & Francis, 2017-08-31)In Patagonia, arid and semiarid lands are being affected both by inappropriate management practices, which are leading to degradation, and by volcanic activity, whose effects are still unclear. This study aimed to test ... -
Una herramienta para monitorear sequías en regiones áridas y semiáridas de Patagonia Norte
(Gerencia de Comunicación e Imagen Institucional, DNA SICC, INTA, 2012-08)La variabilidad ambiental es una característica de regiones pastoriles áridas y semiáridas, siendo la sequía uno de los principales problemas en sistemas ganaderos extensivos, con implicancias productivas y económicas tanto ... -
Integrating family farmers’ perceptions with meteorological records and national climate change projections to enhance site-specific adaptation knowledge
(Springer, 2023-12)Adaptation strategies to climate change (CC) that do not consider local perspectives tend to fail at specifc sites. Searching for complementary actions, we aimed to assess how farmers’ perceptions about climatic hazards ... -
Local adaptation along a sharp rainfall gradient occurs in a native Patagonian grass, Festuca pallescens, regardless of extensive gene flow
(Elsevier, 2020-03)Increasing global aridity combined with changing environmental conditions might cause irreparable alterations in arid and semiarid ecosystems. Knowledge of within-species genetic diversity and adaptive responses, especially ... -
Tracking floristic archetypes of Patagonian steppes
(Wiley, 2024-03)Questions: The classification of plant communities is a well-established practice in ecology. However, the factors that determine the distribution of common species and the extent of their dominance and overlap are still ... -
Zero net livelihood degradation - the quest for a multidimensional protocol to combat desertification
(2016)Recientemente se propuso el concepto de degradación de la tierra neta nula como base para un futuro protocolo de la Convención de las Naciones Unidas de lucha contra la desertificación para reducir la degradación mundial ...
