Mapping extinction debt highlights conservation opportunities for birds and mammals in the south American Chaco
(2018-02)Habitat loss is the primary cause of local extinctions. Yet, there is considerable uncertainty regarding how fast species respond to habitat loss, and how time‐delayed responses vary in space. We focused on the Argentine ... -
Mapping QTL for resistance to new virulent races of wheat stripe rust from two Argentinean wheat cultivars
(Crop Science Society of America, 2018)During the last two decades, new virulent and aggressive races of Puccinia striiformis Westend. f. sp. tritici (Pst) have spread worldwide, causing devastating epidemics and prompting the search for new sources of resistance ... -
Mapping the soils of an Argentine Pampas region using structural equation modeling
(2016-11)Current digital soil mapping (DSM) methods have limitations. For instance, it is difficult to predict a large number of soil properties simultaneously, while preserving the relationships between them. Another problem is ... -

Lam, es una especie de importancia agrícola, que se cultiva en más de 100 países con una producción anual de 120 millones de toneladas. Esta especie presenta una raíz engrosada denominada batata que ... -
Marriage between variable selection and prediction methods to model plant disease risk
(Elsevier, 2023-10-11)Predicting the risk of a disease in a pathosystem based on a set of climatic variables usually requires handling a high number of input variables, many of which are often irrelevant and/or redundant. Building linear ... -
Mastitis tuberculosa en bovinos de leche : reporte de casos
(Asosiación Argentina de Veterinarios de Laboratorios de Díagnóstico, 2018-11)La tuberculosis bovina (TB) es una enfermedad del ganado producida principalmente, por Mycobacterium bovis (M. bovis). Aunque es conocido el riesgo de infección en terneros asociados al manejo del calostro y leche (Evangelista ... -
Mate choice confers direct benefits to females of Anastrepha fraterculus (Diptera: Tephritidae)
(Public Library of Science, 2019-06)Exposure to plant compounds and analogues of juvenile hormone (JH) increase male mating success in several species of tephritid fruit flies. Most of these species exhibit a lek mating system, characterized by active female ... -
El material parental de los suelos de la Región Pampeana en base a la mineralogía de arenas. Aplicaciones a la interpretación de procesos pedológicos
(Asociación Argentina de Ciencia del Suelo, 2020-11-06)La influencia de la mineralogía y la granulometría del material parental en las características edáficas son particularmente importantes en suelos jóvenes desarrollados en superficies del Pleistoceno o más recientes. Así, ... -
Mating-induced changes in responses of female Queensland fruit fly to male pheromones and fruit : a mechanism for mating-induced sexual inhibition
(Elsevier, 2021-03)In order to reproduce, female tephritid fruit flies need both mates for fertilization and fruit for oviposition. Virgin females are prone to mating and approach males, attracted by their pheromones. Mated females, however, ... -
