Socio-technical networks modulate on-farm technological innovations in wool production of North Patagonia, Argentina
(Elsevier, 2021-03)Socio-technical networks in the agricultural sector are complex and are key in technological innovation processes. Some relevant on-farm management decisions depend on a negotiation process involving different factors, ... -
Spatial distribution of volcanic ash deposits of 2011 Puyehue-Cordón Caulle eruption in Patagonia as measured by a perturbation in NDVI temporal dynamics
(2018-03)Volcanic ash fallout is a recurrent environmental disturbance in forests, arid and semi-arid rangelands of Patagonia, South America. The ash deposits over large areas are responsible for several impacts on ecological ... -
Spatial dynamics of a Sirex noctilio woodwasp population within a pine plantation in Patagonia, Argentina
(Wiley, 2007-12)The woodwasp Sirex noctilio F. (Hymenoptera: Siricidae) is probably the most important pest of pine tree plantations of the southern hemisphere. We studied the spatial arrangement of an endemic population of the woodwasp ... -
Spontaneous outbreak of Astragalus pehuenches (Fabaceae) poisoning in cattle in Argentina
(Elsevier, 2018-11)This is the first report of a spontaneous outbreak of Astragalus pehuenches poisoning on a farm in Argentine Patagonia, where 63 out of 70 cattle died. The main clinical signs of affected animals were ataxia, balance loss ... -
Staying close: short local dispersal distances on a managed forest of two Patagonian Nothofagus species
(Oxford University Press, 2020-05)Understanding the impact of management on the dispersal potential of forest tree species is pivotal in the context of global change, given the implications of gene flow on species evolution. We aimed to determine the effect ... -
Strains in Sustainability Debates: Traditional Ecological Knowledge and Western Science through the Lens of Extension Agents in a Pastoral Region
(Wiley Online Library, 2020-03)Those involved in sustainability debates on developmental pathways concur in the synergistic potential of integrating traditional ecological knowledge (TEK) and Western scientific approaches. Transhumant pastoralism is a ... -
Structural–functional approach to identify post-disturbance recovery indicators in forests from northwestern Patagonia: a tool to prevent state transitions
(Elsevier, 2015-05)The disruption of the natural post-disturbance recovery process, either by changes in disturbance regime or by another disturbance, can trigger transitions to alternative degraded states. In a scenario of high disturbance ... -
