Minimills, una alternativa de pequeña escala para agregar valor a las fibras textiles
(EEA Bariloche, 2014)Las Minimills o mini-hilanderías llegaron a la Argentina para facilitar el agregado de valor en pequeña escala a la lana y a otras fibras textiles producidas por caprinos y camélidos. Ya funcionan dos Minimills produciendo ... -
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 alternativo para Norpatagonia: madera estructural con pino ponderosa
(Red Argentina de Ciencia y Tecnología Forestal, 2023-03)En el preciso momento en que escribimos estas líneas, la población mundial alcanza los 8.000 millones de habitantes, un “hito en el desarrollo de la humanidad”. Naciones Unidas (ONU), estima que la población mundial crecerá ... -
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 ... -
