Efecto de la severidad de quemado sobre la regeneración de la vegetación en el Monte Austral
(Asociación Argentina de Ecología, 2007-06)El fuego es un fenómeno recurrente en los ecosistemas del norte de la Patagonia y ocurren, fundamentalmente, luego de una serie de años húmedos que promueve el crecimiento de pastos. La acumulación de material combustible ... -
Circadian oscillation of gibberellin signaling in Arabidopsis
(National Academy of Sciences, 2011-05)Circadian clocks are endogenous timekeeping mechanisms that allow organisms to anticipate rhythmic, daily environmental changes. Temporal coordination of transcription results in a set of gene expression patterns with ... -
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, ... -
Convergence between satellite information and farmers’ perception of drought in rangelands of North-West Patagonia, Argentina
(Elsevier, 2020-09)Drought is a complex natural hazard with social and environmental implications. Satellite information is increasingly used to support decision-makers in preventing or coping with the negative impacts of drought. The ... -
Urolitiasis en pequeños rumiantes
(Facultad de Agronomía y Veterinaria, Universidad Nacional de Río Cuarto, 2020-06)La urolitiasis es una enfermedad del tracto urinario que afecta a ovinos y caprinos siendo más frecuente en producciones intensivas y semi-intensivas. Clínicamente se caracteriza por depresión, letargia, rechinar de dientes, ... -
Assessing resilience and adaptability in agroecological transitions
(Elsevier, 2020-09)Guidelines are needed to support research and action on sustainable transitions towards more resilient and adaptable agroecosystems. Here I present an operationable and simple framework with theoretical underpinning to ... -
Repeated maternal separation: Alcohol consumption, anxious behavior and corticosterone were reversed by a non-pharmacological treatment
(Elsevier, 2019-12-29)Adverse events in early life have been related to a maladaptive stress response during adulthood, which could predispose individuals to psychiatric and physiological disorders. The purpose of this work was to study the ... -
A Framework to tackling the synchrony between Social and Ecological phases of the annual cyclic movement of transhumant pastoralism
(MDPI, 2020-04)Transhumant pastoralism is mobile livelihood strategy in which families and their herds move seasonally from lowlands, where they settle during the winter, towards the highlands, located in mountainous areas, during the ... -
Evidence of genetic determination in the growth habit of Nothofagus pumilio (Poepp. & Endl.) Krasser at the extremes of an elevation gradient
(Taylor & Francis, 2020)In temperate mountainous regions, altitudinal clines in tree size and growth habit develop from a gradual adjustment of multiple traits to tolerate harshening conditions with altitude. We perform a common garden trial with ... -
Drosophila suzukii (Diptera: Drosophilidae) distribution modelling improves our understanding of pest range limits
(Taylor & Francis, 2019)Spatial distributions models (SDM) are often used in invasive pest management to understand current and potential distribution. Using data on the well-studied spotted wing drosophila as a model, we compared distribution ... -
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 ... -
Receta práctica paso a paso para construir dendrómetros de punto de bajo costo
(Asociación Argentina de Ecología, 2020-08)Los dendrómetros automáticos de punto son equipos de medición que se usan en la actividad forestal para medir en alta resolución espacial y temporal las variaciones en el fuste de los árboles. Esta información con gran ... -
High genetic variation in marginal fragmented populations at extreme climatic conditions of the Patagonian Cypress Austrocedrus chilensis
(Elsevier, 2010-03)Knowledge about current patterns of genetic structure of populations together with the evolutionary history of a species helps to understand and predict the adaptation of populations to future climate change. We assayed ... -
Food partitioning between the Mara (Dolichotis patagonum) and the introduced hare (Lepus europaeus) in the Monte desert, Argentina
(Taylor & Francis, 1997)In the semiarid Monte desert, Río Negro province, the mara (Dolichotis patagonum) and the European hare (Lepus europaeus), which was introduced about hundred years ago, today occur sympatrically, as in many regions of ... -
Agroecosystem patterns and land management co-develop through environment, management, and land-use interactions
(Wiley, 2020-04)A poor understanding of the interactions between biophysical and social elements within rural mountainous landscapes can lead to suboptimal management and recommendations. The objective of this study was to contribute to ... -
Evaluación de la precisión y la exactitud de equipos de laboratorios que determinan la calidad de fibras de ovinos
(Facultad de Medicina Veterinaria, Universidad Nacional Mayor de San Marcos, 2020)El estudio tuvo como objetivo evaluar la precisión y exactitud de equipos que determinan la calidad de fibras de ovinos. Los equipos utilizados (total = 15) fueron Sirolan Laserscan, OFDA 2000, Minifiber EC y Fiber EC, ... -
Falla en la eficacia de dos formulaciones de ivermectina contra Psoroptes ovis (Hering, 1838) en ovinos
(Faculta de Ciencias Veterinarias, Universidad Nacional del Litoral, 2020-06)El presente trabajo evaluó la relación entre la eficacia y la farmacocinética de dos formulaciones comerciales inyectables de ivermectina (IVM) en ovinos merino adultos artificialmente infestados con Psoroptes ovis. Los ... -
Integrating circadian and gibberellin signaling in Arabidopsis : Possible links between the circadian clock and the AtGID1 transcription
(Taylor & Francis, 2011-09)The circadian clock acts as central coordinator of plant activity, and it regulates key traits for plant fitness such as flowering time, gas exchange, growth and stress responses. In the May issue of the Proceedings of the ... -
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 ... -
