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 ... -
Antecedentes y situación epidemiológica de la Brucelosis bovina en la Región Patagónica Argentina
(Sociedad de Medicina Veterinaria, 2004)Se realizó una recopilación y análisis de la información técnica disponible sobre Brucelosis Bovina de la Patagonia Argentina. Se confirma la presencia de la enfermedad en dicha región desde la década del 50 y su actual ... -
Antimicrobial resistance dissemination associated with intensive animal production practices in Argentina: A systematic review and meta-analysis
(Elsevier, 2023-03)Abuse and misuse of antimicrobial agents has accelerated the spread of antimicrobial-resistant bacteria. The association between antimicrobial-resistant infections in humans and antimicrobial use in agriculture is complex, ... -
Antioxidant capacity of frozen Pleurotus ostreatus during convective drying
(Universidad de Puebla, México, 2016-01)The influence of drying conditions on antiradical power, total phenols, flavonoids, and surface color in frozen basidiocarps of Pleurotus ostreatus was studied. Drying was carried out in an experimental rig, air velocity ... -
Aplicación de leyes fundamentales de la densidad a bosques de Nothofagus: II. Línea de inicio de competencia y diagramas de manejo de la densidad = Applicability of density rules on Nothofagus forests: II. The minimum stocking line and stand-density management diagram
(Facultad de Ciencias Forestales y Recursos Naturales, Universidad Austral de Chile, 2001)Continuando con el estudio de relaciones funcionales de la densidad de rodales mixtos de Nothofagus, se ajustó una expresión entre el área de proyección de la copa y el diámetro de árboles libres de competencia, que permitió ... -
Aplicación de leyes fundamentales de la densidad a bosques de Nothofagus: I. Regla de los -3/2 o ley del autorraleo = Applicability of density rules on Nothofagus forests: I. The -3/ 2 power law or self-thinning
(Facultad de Ciencias Forestales y Recursos Naturales, Universidad Austral de Chile, 1999-12-31)Con el fin de interpretar la dinámica de los bosques de Nothofagus de Norpatagonia-Argentina, se han estudiado los comportamientos de algunas leyes fundamentales relacionadas con la densidad y mortalidad de los rodales. ... -
