Aerobic Metabolism Alterations as an Evidence of Underlying Deltamethrin Resistance Mechanisms in Triatoma infestans (Hemiptera: Reduviidae)
(Entomological Society of America, 2020-06)Triatoma infestans (Klug, 1834), the main vector of Chagas disease in Latin America, is regularly controlled by spraying the pyrethroid deltamethrin, to which some populations have developed resistance. The three main ... -
Fatal stagger poisoning by consumption of Festuca argentina (Speg.) Parodi in goats from Argentine Patagonia
(Elsevier, 2020-10-30)The present study describes the spontaneous and experimental poisoning of goats by Festuca argentina in Argentine Patagonia. In April 2017, eight seven-month-old Creole male goats were accidentally introduced into a paddock ... -
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 ... -
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 ... -
