Characterization of camel fibers in regions of Kazakhstan and Uzbekistan
(2014-03)To generate information on Central Asian camel fiber quality, fiber samples of 712 camels from Kazakhstan and Uzbekistan were characterized. Fixed effects involved geographical location, animal age, sex, coat color and ... -
Functional diversity of phytochrome family in the control of light and gibberellin-mediated germination in Arabidopsis
(Wiley, 2014-03)In several species, seed germination is regulated by light in a way that restricts seedling emergence to the environmental conditions that are likely to be favourable for the success of the new individual, and therefore, ... -
First study of host-plant preferences of Sinopla perpunctatus (Hemiptera: Acanthosomatidae), a stink bug from the Andean-Patagonic forest

Pretreatments Effect in Drying Behaviour and Colour of Mature and Immature ‘Napolitana’ Sweet Cherries
(Springer, 2014-06)The effect of different treatments on drying behaviour and colour of mature and immature cherries (Napolitana var.) has been studied. Drying was carried out at 70 °C with air at 4 m/s speed and 8 % relative humidity, and ... -
Influencia de los rasgos de historia de vida y del uso de información en la adquisición de recursos y dispersión en el parasitoide Ibalia leucospoides Hochenwarth (Hymenoptera: Ibaliidae)
(Facultad de Ciencias Exactas y Naturales, Universidad de Buenos Aires, 2014-07)El objetivo central de esta tesis es estudiar como la selección natural moldea los rasgos de historia de vida y el comportamiento de los animales de acuerdo al entorno ecológico en el que viven. Este marco teórico nos ... -
Repeatability of superovulatory response to succesive FSH treatments in Merino sheep
(2014-07)La eficiencia de un programa de la ovulación y la transferencia de embriones múltiples depende de la recuperación de un gran número de embriones viables por oveja donante en cada superovulatorio sucesiva tratamiento. ... -
Lo rural y lo científico: La presencia de la Estación Experimental Regional Agropecuaria (EERA) INTA Bariloche 1962-1968
(Universidad Nacional de Quilmes, 2014-07)En este trabajo se discute el modo en que desde una práctica científica se toma lo rural en la estepa norpatagónica durante la segunda mitad del siglo XX, observando la intervención de estudios científicos asociados a la ... -
Caracterización xilo-tecnológica de la madera de una plantación adulta de Pinus ponderosa de la patagonia argentina
(Gerencia de Comunicación e Imagen Institucional, DNA SICC, INTA, 2014-08)El conocimiento de las propiedades de la madera es esencial para su mejor utilización. Las maderas juvenil y madura difieren en su aptitud de uso, la primera puede emplearse como madera redonda o estructural limitada en ... -
Transgénesis: una moderna biotecnología reproductiva en animales de interés zootécnico
(Gerencia de Comunicación e Imagen Institucional, DNA SICC, INTA, 2014-08)Los continuos avances en el conocimiento de la biología molecular han permitido un gran progreso de la ciencia, mediante la modificación genética tanto de virus, bacterias como de organismos superiores. Estos procedimientos ... -
Sirex noctilio flight behavior : towards improving current monitoring techniques
(2014-08)Sirex noctilio Fabricius (Hymenoptera: Siricidae), una avispa invasora de España y el Norte de África, tiene una presencia global en expansión en los bosques de pino. A pesar de que sus poblaciones se gestionan en la mayoría ... -
Avispas exóticas en la Patagonia: la importancia de la ecología de invasiones en el manejo de plagas
(2014-08)El manejo integrado de plagas (MIP) se basa en el conocimiento de la ecología de las especies problema. Se ha sugerido que cuando las plagas son especies invasoras, la comprensión del proceso de invasión puede mejorar aun ... -
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 ... -
Characterization of mohair and cashmere in regions of Kazakhstan, Kyrgyzstan and Uzbekistan
(2014-08)To generate information on animal fiber quality traits in Central Asia, as a prelude to genetic improvement, fiber samples of 495 cashmere goats from Kazakhstan and Uzbekistan, and 448 mohair goats from these two countries ... -
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, ... -
Long-term grazing negatively affects nitrogen dynamics in Northern Patagonian wet meadows
(Elsevier, 2014-10)Wet meadows are seasonally saturated wetlands that can develop in arid and semi-arid areas. In the semi-arid region of North Patagonia, Argentina wet meadows are islands of high net primary productivity surrounded by low ... -
Wood density proxies of adaptive traits linked with resistance to drought in Douglas fir (Pseudotsuga menziesii (Mirb.) Franco)
(Springer, 2014-10)A comparison of dead and surviving Douglas fir trees following the 2003 drought was made to define proxies of adaptive traits for resistance to drought. Increment cores were sampled from trees from three French regions: ... -
Plant species richness and shrub cover attenuate drought effects on ecosystem functioning across Patagonian rangelands
(2014-10-22)Drought is an increasingly common phenomenon in drylands as a consequence of climate change. We used 311 sites across a broad range of environmental conditions in Patagonian rangelands to evaluate how drought severity and ... -
