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 ... -
Melatonin in Arabidopsis thaliana acts as plant growth regulator at low concentrations and preserves seed viability at high concentrations
(2015-09)Since the discovery of melatonin in plants, several roles have been described for different species, organs, and developmental stages. Arabidopsis thaliana, being a model plant species, is adequate to contribute to 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 ... -
Mitochondrial DNA lineages and genetic variation of early growth traits in the Argentinean breeding population of Pinus ponderosa Douglas ex C. Lawson
(Springer, 2024-03)In the Andean-Patagonian region of Argentina, Pinus ponderosa Douglas ex C. Lawson is the most widely cultivated forest tree species. Its breeding program, started in 1998, is now progressing towards the establishment of ... -
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 ... -
Modelling the distribution of forest pest natural enemies across invaded areas: Towards understanding the influence of climate on parasitoid establishment success
(Elsevier, 2019-05)Classical biological control is a pest management practice frequently deployed against invasive insects. However, introduced natural enemies too often fail to establish, and this has been partly explained by climatic ... -
Modelling the establishment, spread and distribution shifts of pests
(Taylor and Francis, 2019)During the last century increasing human trade networks have interacted with other global changes – such as land use and climate change – to accelerate the range expansion of pest species worldwide. In this special issue, ... -
Modelo de estados y transiciones de los ñirantales del NO de la Patagonia como herramienta para el uso silvopastoril sustentable
(Asociación Argentina de Ecología, 2017-08)Desarrollamos un modelo de estados y transiciones (MEyT) para el bosque de ñire (Nothofagus antarctica) en el norte de la Patagonia, con el fin de sintetizar el conocimiento disperso sobre las repuestas de este sistema al ... -
Modelos de crecimiento diamétrico para Nothofagus dombeyi = Diameter growth models for Nothofagus dombeyi
(Facultad de Ciencias Forestales y Recursos Naturales, Universidad Austral de Chile, 2001-12-31)Se desarrollaron varios modelos de crecimiento diamétrico para la especie Nothofagus dombeyi. La función seleccionada para el estudio es no lineal, usualmente denominada Bertalanffy-Richards. La misma se ajustó a partir ... -
Modelos de crecimiento diamétrico para Nothofagus obliqua = Diameter growth models for Nothofagus obliqua
(Facultad de Ciencias Forestales y Recursos Naturales, Universidad Austral de Chile, 2003)Non-linear, Bertalanffy-Richards-type models of diameter growth were developed for Nothofagus obliqua and fitted for different social tree strata using the diameter annual increment (id) and diameter at breast height (dap). ... -
Molecular bases of responses to abiotic stress in trees
(Oxford University Press, 2020-06)Trees are constantly exposed to climate fluctuations, which vary with both time and geographic location. Environmental changes that are outside of the physiological favorable range usually negatively affect plant performance ... -
Molecular characterization of Brucella ovis in Argentina
(Elsevier, 2020-06)Brucellosis in rams is caused by Brucella ovis or Brucella melitensis and it is considered one of the most important infectious diseases of males in sheep-raising countries. Molecular characterization of Brucella spp. ... -
Monthly variations of forcing mechanisms of austral summer precipitation in subtropical Argentina
