Dietary nitrate metabolism and enteric methane mitigation in sheep consuming a protein-deficient diet
(CSIRO Publishing, 2019-09-20)It was hypothesised that the inclusion of nitrate(NO3 –) or cysteamine hydrochloride (CSH) in a protein deficient diet (4.8% crude protein; CP) would improve the productivity of sheep while reducing enteric methane (CH4) ... -
Different drought‑adaptive capacity of a native Patagonian tree species (Nothofagus pumilio) resulting from local adaptation
(Springer, 2021-06)The resistance of different genotypes to abiotic stress may be due to genetic effects and/or to phenotypic plasticity allowing them to acclimate to variable conditions. The contribution of one or the other mechanism ... -
Differential response of natural regeneration to silvopastoral use intensity in mixed forests of northern Patagonia, Argentina
(Elsevier, 2022-07-07)Silvopastoral use (combined livestock and forestry) is widely distributed in South America’s native forests. Without medium to long-term planning, this activity may affect the population dynamics of the dominant canopy ... -
Differential UVR8 Signal across the Stem Controls UV-B–Induced Inflorescence Phototropism
(The American Society of Plant Biologists, 2019-09)In the course of evolution, plants have developed mechanisms that orient their organs toward the incoming light. At the seedling stage, positive phototropism is mainly regulated by phototropin photoreceptors in blue and ... -
Differentiation in phenology among and within natural populations of a South American Nothofagus revealed by a two-year evaluation in a common garden trial
(Elsevier, 2020-03-15)Phenological traits are crucial for understanding adaptation to climate change due to their genetic control and association with abiotic factors. However, few data on phenology patterns are available for South American ... -
Direct and indirect effects of climate and vegetation on sheep production across Patagonian rangelands (Argentina)
(Elsevier, 2021-05)Extensive sheep production is an important agricultural industry in the Patagonia region of Argentina, where the most important production metric is the effective lambing rate of the sheep (L%). Climate factors can affect ... -
Dispersal behavior of yellowjacket (Vespula germanica) queens
(2018-02)Understanding the factors that affect animal dispersal behavior is important from both fundamental and applied perspectives. Dispersal can have clear evolutionary and ecological consequences, but for nonnative insect pests, ... -
Dissecting the Space-Time Structure of Tree-Ring Datasets Using the Partial Triadic Analysis
(Plos One, 2014-09)Tree-ring datasets are used in a variety of circumstances, including archeology, climatology, forest ecology, and wood technology. These data are based on microdensity profiles and consist of a set of tree-ring descriptors, ... -
Distribución natural de Nothofagus alpina y Nothofagus obliqua (nothofagaceae) en Argentina, dos especies de primera importancia forestal de los bosques templados norpatagónicos
(Sociedad Argentina de Botánica, 2011-06)Conocer la distribución natural de cualquier especie es esencial para poder planificar su conservación o uso. El Raulí [Nothofagus alpina (Poepp. & Endl.) Oerst. = Nothofagus nervosa (Phil.) Dim. et Mil.] y el Roble Pellín ... -
Distribution, dispersal and spread of the invasive social wasp (Vespula germanica) in Argentina
(2013-04)Se estudió la distribución y difusión de la avispa invasora sociales Vespula germanica en Argentina, se centra en la contribución de la dispersión de la reina de la expansión territorial. Vespula germanica es originaria ... -
Distribution, Invasion History, and Ecology of Non-native Pine Bark Beetles (Coleoptera: Curculionidae: Scolytinae) in Southern South America
(Springer, 2024-01)The growth of international trade, coupled with an expansion of large-scale pine plantations in South America during the second half of the twentieth century, has significantly increased the opportunities for the invasion ... -
Diversidad de razas caprinas criollas en Argentina
(Red CONBIAND, 2019-06-25)Se estima que el 90% de los casi cinco millones de caprinos en Argentina se pueden asignar a poblaciones locales tradicionalmente llamadas Criollos. Se denomina así a un colectivo indefinido, menospreciado en sus atributos ... -
Do populations of Festuca pallescens from a rainfall gradient differ in the expression of morpho-physiological traits under drought stress?
(Elsevier, 2023-06)In arid environments, stochastic rainfall and high evapotranspiration force plants to optimize water resources. North Patagonia is characterized by a deep rainfall gradient that gives rise to environments with very contrasting ... -
Do Texas Angora bucks improve mohair weight and quality traits of Tajik Angora goats?
(2016)Productores de angora en Tajikistán del Norte levantan alrededor de 200,000 cabras De angora y productos alrededor de 300 toneladas de mohair. ¿Hay aproximadamente 500 productores pequeños, medios y más grandes con 100-500 ... -
Does competition management improve the ecophysiological response to water shortage of mixed woodland species of North Patagonia?
(Elsevier, 2023-08)Globally, the increasing forests vulnerability and drought-induced forest mortality events, extended to a larger scale, may have the potential to rapidly alter forest functioning and the provision of ecosystem services. ... -
Doramectin efficacy against Psoroptes ovis in sheep: Evaluation of pharmacological strategies
(Elsevier, 2020-11)The aims of this study were to evaluate the efficacy of two injectable formulations of doramectin (DRM) against Psoroptes ovis in sheep infested under controlled experimental conditions and to characterize the DRM plasma ... -
Drivers of global Scolytinae invasion patterns
(Ecological Society of America, 2020-02)Biological invasions are affected by characteristics of invading species, strength of pathway connectivity among world regions and habitat characteristics of invaded regions. These factors may interact in complex ways to ... -
Drone aggregation behavior in the social wasp Vespula germanica (Hymenoptera: Vespidae): Effect of kinship and density
(Nature Research, 2020-04)Inbreeding can have negative consequences on population viability because of the reduced fitness of the progeny. In general, most species have developed mechanisms to minimize inbreeding such as dispersal and kin avoidance ... -
Drosophila suzukii (Diptera: Drosophilidae) distribution modelling improves our understanding of pest range limits
