Técnica de la confusión sexual, carpocapsa. Pautas para el uso correcto de la técnica de la confusión sexual en los valles de Río Negro y Neuquén
(EEA Alto Valle, INTA, 2001)El control de carpocapsa se ha basado en los últimos años en el uso de plaguicidas, principalmente piretroides, organofosforados y carbamatos. Hoy en día, la agricultura en general se debe basar en procesos productivos ... -
The Ambrosia Beetle Megaplatypus mutatus: A Threat to Global Broad-Leaved Forest Resources
(Entomological Society of America, 2022-08)We provide scientists and decision-makers with up-to-date information on Megaplatypus mutatus (Coleoptera: Curculionidae: Platypodinae), a forest insect native to South America that has invaded other regions. Emphasis is ... -
The application of ecologically intensive principles to the systemic redesign of livestock farms on native grasslands: A case of co-innovation in Rocha, Uruguay
(Elsevier, 2021-06)CONTEXT: Family-run cow-calf farms based on native grasslands exhibit low economic and social sustainability, as reflected in low family incomes and high workloads. Experimental results have shown that pasture–herd interaction ... -
The educational community and its knowledge and perceptions of native and invasive alien species
(Springer Nature, 2021-11)Environmental education seeks to foster an appreciation for nature and the impact of humans on it while introducing citizens to scientific thinking. Biological invasions affect different aspects of life on earth and mandate ... -
The effect of pre-slaughter stressors on physiological indicators and meat quality traits on Merino lambs
(Elsevier, 2013-04)Merino lambs of 90 days of mean age (standard deviation – s.d. – 6 days) and 22.0 kg of mean live weight (s.d. 2.7 kg) were used to explore the effects of pre-slaughter stressors on physiological characteristics and meat ... -
The effect of weeding time on raspberry (Rubus idaeus L.) crops yield and weed community in Rio Negro Province, Argentina
(Elsevier, 2013-02)Raspberry (Rubus idaeus L.) is the most important crop in the (Andean Shire), an area situated at the south of Rio Negro Province in the south of Argentina. Organic berries production in this area increased significantly ... -
The effects of dietary nitrate on plasma glucose and insulin sensitivity in sheep
(Wiley Online Library, 2019-07)Nitrate (NO3 ¯) is an effective non‐protein nitrogen source for gut microbes and reduces enteric methane (CH4) production in ruminants. Nitrate is reduced to ammonia by rumen bacteria with nitrite (NO2 ¯) produced as an ... -
The effects of Quaternary glaciations in Patagonia as evidenced by chloroplast DNA phylogeography of Southern beech Nothofagus obliqua
(Springer, 2009-03)Climatic oscillations during the Quaternary strongly affected the distribution of warm-temperate tree species, which experienced local restrictions into ice-free areas and posterior expansions. To evaluate the impact of ... -
The effects of volcanic ash from Puyehue-Caulle range eruption on the survival of Dichroplus vittigerum (Orthoptera: Acrididae)
(2013-03)The aim of this work was to evaluate the toxicity of volcanic ash from the volcanic complex Puyehue-Caulle Range on the grasshopper, Dichroplus vittigerum, and compare the results with the effect of diatomaceous earth, an ... -
The impact of different natural environments on the regeneration dynamics of two Nothofagus species across elevation in the southern Andes
(Elsevier, 2020-05-15)A widely accepted paradigm in forest ecology proposes that patterns of relative abundance among mature forest trees are largely influenced by biotic and abiotic processes that operate most intensely during the earliest ... -
The Influence of Food and Con-specifics on the Flight Potential of the Parasitoid Ibalia leucospoides
(Springer, 2011-11)For insect parasitoids, knowledge of their flight capability is essential for a general understanding of the relationship with their hosts. For instance, flight capacity might partly determine their efficacy as biological ... -
The influence of local environmental and socio-economic conditions on the impacts of ash storms
(2018-09-02)Volcanic ash wind-induced remobilization events have increasingly been reported in different areas around the worl during the last decades -
The origins of global invasions of the German wasp (Vespula germanica) and its infection with four honey bee viruses
(Springer, 2018-12)A successful control or eradication programme using biological control or genetically-mediated methods requires knowledge of the origin and the extent of wasp genetic diversity. Mitochondrial DNA variation in the native ... -
The sign and magnitude of tree–grass interaction along a global environmental gradient
(2016-12)Aim: The ecological literature posits that positive interactions are preponderant in stressful environments; however, the net balance between positive and negative interactions at the community level is still under debate. ... -
The Use of hCG for Inducing Ovulation in Sheep Estrus Synchronization Impairs Ovulatory Follicle Growth and Fertility
(MDPI, 2021-04)Currently, there is an intense effort to find an alternative hormone to eCG to induce ovulation after estrus synchronization treatments in sheep. One of the proposed alternatives is based on the use of hCG, but the results ... -
Think globally, measure locally: The MIREN standardized protocol for monitoring plant species distributions along elevation gradients
(Wiley, 2022-02)Climate change and other global change drivers threaten plant diversity in mountains worldwide. A widely documented response to such environmental modifications is for plant species to change their elevational ranges. Range ... -
Three easy fixes for sire use can enhance genetic progress in community-based breeding programmes
(Wiley, 2021)We analysed options to optimize the use of sires in sheep and goat community-based breeding programmes (CBBP) for three scenarios occurring under field conditions: premature sale of selection candidates, fixed service ... -
Tiempo de pariciones. Recomendaciones generales
(AER Chos-Malal, INTA, 2022-10)En el norte de la Patagonia las pariciones de caprinos y ovinos se concentran en los meses de primavera . Compartimos recomendaciones generales a tener en cuenta para un adecuado manejo de los animales en tiempo de parición. -
Timing of nitrogen fertilization influences color and anthocyanin content of apple (Malus domestica Borkh. cv ‘Royal Gala’) fruits
(Taylor and Francis, 2011)Different timings and methods of N application modify N dynamics in the plant and could have differential effects on fruit color. To evaluate this possibility, an experiment was conducted during three seasons in a ‘Royal ... -
