Modeling of the annual cycle of Melophagus Ovinus (L.) in two sheeps flocks of Patagonia, Argentina
(2018-03)The ked Melophagus ovinus (L.), one of the most common obligate external parasites in sheep, is a recurrent problem in temperate sheep production areas worldwide. Modeling of its annual dynamics, which is lacking, can ... -
Modelling the distribution of forest pest natural enemies across invaded areas: Towards understanding the influence of climate on parasitoid establishment success
(Elsevier, 2019-05)Classical biological control is a pest management practice frequently deployed against invasive insects. However, introduced natural enemies too often fail to establish, and this has been partly explained by climatic ... -
Modelling the establishment, spread and distribution shifts of pests
(Taylor and Francis, 2019)During the last century increasing human trade networks have interacted with other global changes – such as land use and climate change – to accelerate the range expansion of pest species worldwide. In this special issue, ... -
Modelo de estados y transiciones de los ñirantales del NO de la Patagonia como herramienta para el uso silvopastoril sustentable
(Asociación Argentina de Ecología, 2017-08)Desarrollamos un modelo de estados y transiciones (MEyT) para el bosque de ñire (Nothofagus antarctica) en el norte de la Patagonia, con el fin de sintetizar el conocimiento disperso sobre las repuestas de este sistema al ... -
Modelos de crecimiento diamétrico para Nothofagus dombeyi = Diameter growth models for Nothofagus dombeyi
(Facultad de Ciencias Forestales y Recursos Naturales, Universidad Austral de Chile, 2001-12-31)Se desarrollaron varios modelos de crecimiento diamétrico para la especie Nothofagus dombeyi. La función seleccionada para el estudio es no lineal, usualmente denominada Bertalanffy-Richards. La misma se ajustó a partir ... -
Modelos de crecimiento diamétrico para Nothofagus obliqua = Diameter growth models for Nothofagus obliqua
(Facultad de Ciencias Forestales y Recursos Naturales, Universidad Austral de Chile, 2003)Non-linear, Bertalanffy-Richards-type models of diameter growth were developed for Nothofagus obliqua and fitted for different social tree strata using the diameter annual increment (id) and diameter at breast height (dap). ... -
Molecular bases of responses to abiotic stress in trees
(Oxford University Press, 2020-06)Trees are constantly exposed to climate fluctuations, which vary with both time and geographic location. Environmental changes that are outside of the physiological favorable range usually negatively affect plant performance ... -
Molecular characterization of Brucella ovis in Argentina
(Elsevier, 2020-06)Brucellosis in rams is caused by Brucella ovis or Brucella melitensis and it is considered one of the most important infectious diseases of males in sheep-raising countries. Molecular characterization of Brucella spp. ... -
Monthly variations of forcing mechanisms of austral summer precipitation in subtropical Argentina
(Elsevier, 2023-04)Summer precipitation is a crucial variable for Subtropical Argentina (STAr) from a social and economic perspective. Monthly forcing mechanism variations of subregional summer precipitation over STAr are studied. Most ... -
Morpho-physiological responses of Nothofagus obliqua to light intensity and water status, with focus on primary growth dynamics
(Springer Nature, 2018-10)Primary growth affects plant plasticity by influencing the number, spatial arrangement and time of differentiation of the leaves. For Nothofagus obliqua, we evaluated if primary shoot growth dynamics determines short-term ... -
The Morphological Basis of vicuña wool: Skin and gland structure in Vicugna vicugna (Molina 1782)
(2016-04)The vicuña (Vicugna vicugna) is the smallest member of the Camelidae with one of the most valuable fibers in the world. However, little is known of the structural basis for this fiber or of the skin glands used in chemical ... -
Mulinum spinosum y la carne de cordero: detección de su presencia en ovinos vivos = Mulinum spinosum and lamb meat: detecting its presence on live sheep
(UCOPress. Cordoba University Press, 2011)En Patagonia, la ganadería ovina es una de las principales actividades económicas, pero la calidad de la carne de cordero se ve afectada por el sabor desagradable que toma a causa de la ingesta de neneo (Mulinum spinosum ... -
Natives helping foreigners? The effect of inoculation of poplar with patagonian beneficial microorganisms
(2017-12)Inoculation with microorganisms represents an opportunity to enhance tree production, directly affecting plant growth or survival at planting. The aim of the present study was to evaluate the effect of mixed inoculation ... -
Neo-sex chromosomes in the Masculipennis species group (Dichroplus: Acrididae, Melanoplinae) : the cases of D. masculipennis and D. vittigerum
(2016)Los saltamontes de melanoplina de América del Sur muestran un número desproporcionado de cariotipos derivados, incluyendo muchos casos de sistemas cromosómicos neo-sexuales. Esto es especialmente cierto para el género ... -
Nest-departure behaviour of gynes and drones in the invasive yellowjacket Vespula germanica (Hymenoptera: Vespidae)
(Cambridge University Press, 2020-08)Inbreeding costs can be high in haplodiploid hymenopterans due to their particular mechanism of sex determination (i.e., single-locus complementary sex-determination system, sl-CSD), as it can lead to the production of ... -

New precipitation and temperature grids for northern Patagonia: Advances in relation to global climate grids
(Chinese Meteorological Society, 2016-02)Climate data of mean monthly temperature and total monthly precipitation compiled from different sources in northern Patagonia were interpolated to 20-km resolution grids over the period 1997–2010. This northern Patagonian ... -
New world goat populations are a genetically diverse reservoir for future use
(Springer Nature, 2019-02-06)Western hemisphere goats have European, African and Central Asian origins, and some local or rare breeds are reported to be adapted to their environments and economically important. By-in-large these genetic resources have ... -
