Detection of swainsonine-producing endophytes in Patagonian Astragalus species
(Elsevier, 2019-12)Swainsonine has been identified as the toxin in legumes belonging to the genera Astragalus and Oxytropis throughout the world including China, North America, and South America. Several South American Astragalus species ... -
Determining the origin of invasions and demonstrating a lack of enemy release from microsporidian pathogens in the common wasps (Vespula vulgaris)
(2014-08)La comprensión del papel de la liberación de enemigo en las invasiones biológicas requiere una evaluación del área de distribución del invasor, el número de eventos de invasión y la prevalencia del enemigo. La avispa común ... -
Development and evaluation of a species-specific PCR assay for the detection of Brucella ovis infection in rams
(Elsevier, 2010)Brucella ovis infection is a major cause of epididymitis and infertility in rams, resulting in reproductive failure and significant economic losses worldwide. The goal of this study was to develop a PCR test targeting ... -
Development of a duplex PCR for the identification of Fasciola hepatica in lymnaeid snails
(Ediciones INTA, 2020-12)Fasciola hepatica is a parasitic trematode that causes fascioliasis, a disease that affects domestic livestock and humans. The complex life cycle of F. hepatica involves lymnaeid snails as intermediate hosts. Detection of ... -
Development of genomic resources for Nothofagus species using next‐generation sequencing data
(Wiley, 2014-11)Using next‐generation sequencing, we developed the first whole‐genome resources for two hybridizing Nothofagus species of the Patagonian forests that crucially lack genomic data, despite their ecological and industrial ... -
Diagramas de manejo de densidad para renovales de roble, raulí y coigüe en Chile = Stocking management charts for roble, raulí and coigüe second growth forests in Chile
(Facultad de Ciencias Forestales y Recursos Naturales, Universidad Austral de Chile, 2007)A total of 214 permanent and temporary plots from roble (Nothofagus obliqua ), raulí (N. alpina) and coigüe (N. dombeyi) pure and mixed second growth forests located between 37°30 and 42°00 south latitude in Chile were ... -
Dietary nitrate and presence of protozoa increase nitrate and nitrite reduction in the rumen of sheep
(Wiley, 2020-04)Nitrate (NO−3) supplementation is an effective methane (CH4) mitigation strategy for ruminants but may produce nitrite (NO−2) toxicity. It has been reported that rumen protozoa have greater ability for NO−3 and NO−2 reduction ... -
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
