Long-term grazing negatively affects nitrogen dynamics in Northern Patagonian wet meadows
(Elsevier, 2014-10)Wet meadows are seasonally saturated wetlands that can develop in arid and semi-arid areas. In the semi-arid region of North Patagonia, Argentina wet meadows are islands of high net primary productivity surrounded by low ... -
Long-term monitoring reveals the effect of precipitation and silviculture on Nothofagus regeneration in Northern Patagonia mixed forests
(Springer, 2024-04)Background: Tree regeneration is a key component of resilience because it promotes post-disturbance recovery of forests. Northwestern Patagonia from Argentina is occupied by Nothofagus alpina (Na), N. obliqua (No), and N. ... -
Management of Nothofagus genetic resources: Definition of genetic zones based on a combination of nuclear and chloroplast marker data
(Elsevier, 2013-08-15)Development of appropriate forest conservation and management measures for a given tree species includes the identification of distinct genetically homogeneous units across its overall distribution range, which depends on ... -

(Facultad de Ciencias Forestales y Recursos Naturales, Universidad Austral de Chile, 2023-05)El Manejo del Bosque con Ganadería Integrada (MBGI) es una propuesta técnica que se basa en el manejo de los componentes forestal, ganadero, forrajero y ambiental, articulada como un plan predial factible de implementar. ... -
Manejo nutricional pre y post-destete en crias de cabras angora del norte de la patagonia
(Facultad de Ciencias Veterinarias, Universidad Nacional de La Pampa, 2021-12)En los hatos de cabras Angora en el norte de la región Patagónica, las crías suelen manifestar deficiencias nutricionales desde el nacimiento hasta el destete a los 90 días que se asocian a bajas tasas de señalada y destete, ... -
Maqui (Aristotelia chilensis [Mol.] Stuntz) morphological and phenolic traits associated with forests type and latitudinal gradient in natural populations of Patagonia Argentina
(Elsevier, 2021-12)Maqui (Aristotelia chilensis [Mol.] Stuntz) is a native berry of the Patagonia Andean forests, which has one of the highest antioxidant levels currently known. This biochemical characteristic strongly depends on the phenolic ... -
Mass fux decay timescales of volcanic particles due to aeolian processes in the Argentinian Patagonia steppe
(Springer Nature, 2020-09)We investigate the timescales of the horizontal mass flux decay of wind remobilised volcanic particles in Argentina, associated with the tephra-fallout deposit produced by the 2011–2012 Cordón Caulle (Chile) eruption. ... -
Mate-searching behavior in the invasive German wasp, Vespula germanica, in Patagonia
(John Wiley & Sons Ltd, 2018-07)In order to increase the probability of reproduction, social insects can adopt various mate‐finding strategies, such as increasing densities of males at specific locations, and/or visual and chemical cues that attract the ... -
El Mes de la Entomología: acercando el laboratorio de investigación científca a las escuelas de nivel inicial de la Patagonia = Entomology Month: Bringing Scientifc Research Closer to Elementary Schools in Patagonia
(Asociación de Docentes de Ciencias Biológicas, 2015)Como investigadores en ciencias, entendemos que enseñar las ciencias naturales en la escuela primaria es un desafío para los docentes y una excelente oportunidad para sentar las bases del pensamiento científico. “El Mes ... -
Micro-Environmental Variation in Soil Microbial Biodiversity in Forest Frontier Ecosystems—Implications for Sustainability Assessments
(MDPI, 2024-02)Soil health indicators based on microbial biodiversity are increasingly used in agricultural sustainability assessments. However, little is known about how microbial communities vary within micro-environmental gradients ... -
Mixed Nothofagus forest management: a crucial link between regeneration, site and microsite conditions
(Springer Nature, 2020)Canopy openings due to harvesting practices constitute a disturbance that changes the environmental conditions of microsites. Its impact on the relative performance of the regeneration of different tree species could also ... -
Modeling leaf maximum net photosynthetic rate of Festuca pallescens, the dominant perennial grass of Patagonian pine-based silvopastoral systems
(2011-09)The integrated relationship in a simple mechanistic model between the critical environmental factors controlling leaf photosynthesis of understory species would be a useful tool to optimize the management of the silvopastoral ... -
Modeling of the annual cycle of Melophagus Ovinus (L.) in two sheeps flocks of Patagonia, Argentina
(2018-03)The ked Melophagus ovinus (L.), one of the most common obligate external parasites in sheep, is a recurrent problem in temperate sheep production areas worldwide. Modeling of its annual dynamics, which is lacking, can ... -
