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 ... -
Adaptability to climate change in forestry species : drought effects on growth and wood anatomy of ponderosa pines growing at different competition levels
(2012)More stressful conditions are expected due to climatic change in several regions, including Patagonia, South-America. In this region, there are no studies about the impact of severe drought events on growth and wood ... -
Climate warming differently affects Larix decidua ring formation at each end of a French Alps elevational gradient
(Springer, 2020-06)Key message The ongoing global warming tends to reduce Larix decidua radial growth and ring wood density at the bottom of an elevational gradient in the French Alps, while it has a less marked effect at the top. Context: ... -
Comparing temperature data sources for use in species distribution models: From in‐situ logging to remote sensing
(Wiley, 2019-11)Although species distribution models (SDMs) traditionally link species occurrences to free‐air temperature data at coarse spatio‐temporal resolution, the distribution of organisms might instead be driven by temperatures ... -
Coping or adapting strategies? The importance of distinguishing between climatic shift and drought events for proper management of the pastoral systems in Northern Patagonia
(Springer, 2024-02)Drier conditions have been observed in Northern Patagonia, Argentina, in the last decades, affecting the pastoralism production system. In this context, two laws were promoted to foster goat and sheep production. This ... -
Differentiation in phenology among and within natural populations of a South American Nothofagus revealed by a two-year evaluation in a common garden trial
(Elsevier, 2020-03-15)Phenological traits are crucial for understanding adaptation to climate change due to their genetic control and association with abiotic factors. However, few data on phenology patterns are available for South American ... -
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, ... -
Drylands becoming drier: evidence from North Patagonia, Argentina
(Springer, 2023-12)In the last decades, Northern Patagonia (Argentina) has shown linear trends to drier conditions in distinct hydrological variables. Therefore, North Patagonia climate changes were studied using streamfow data of Neuquén ... -
Factors influencing the effectiveness of group interactions among international and interdisciplinary early‑career researchers working toward environmental sustainability in climate change
(Springer, 2022-11)Global warming is a current problem that needs to be addressed by collaborating with researchers from different disciplines and expertise. There is a concern about training the next generation of scientists to holistically ... -
Genetic variation for tolerance to high temperatures in a population of Drosophila melanogaster
(John Wiley & Sons Ltd, 2018-10)The range of thermal tolerance is one of the main factors influencing the geographic distribution of species. Climate change projections predict increases in average and extreme temperatures over the coming decades; hence, ... -
Genomic responses to climate: Understanding local adaptation in the Andean tree species Nothofagus pumilio and implications for a changing world
(Wiley, 2024-03)Nothofagus pumilio is a foundation tree species that inhabits a 2000-km-long range in the southern Andes, a region with two perpendicular environmental gradients: temperature and photoperiod (North–South), and precipitation ... -
Grazing and ecosystem service delivery in global drylands
(American Association for the Advancement of Science, 2022-11-25)Grazing represents the most extensive use of land worldwide. Yet its impacts on ecosystem services remain uncertain because pervasive interactions between grazing pressure, climate, soil properties, and biodiversity may ... -
Growth response of Pinus contorta to the synergy of stress factors: successive extreme drought events and a population outbreak of Sirex noctilio in NW Patagonia
(Springer, 2022-02)The synergy of biotic and abiotic stress factors influences the response in growth, resistance, recovery and resilience of forest systems. This study used a dendrochronological approach to analyze the annual radial increase ... -
Integrating family farmers’ perceptions with meteorological records and national climate change projections to enhance site-specific adaptation knowledge
(Springer, 2023-12)Adaptation strategies to climate change (CC) that do not consider local perspectives tend to fail at specifc sites. Searching for complementary actions, we aimed to assess how farmers’ perceptions about climatic hazards ... -
Integrating genetics and suitability modelling to bolster climate change adaptation planning in Patagonian nothofagus forests
(2017)We investigated the impact of past changes in habitat suitability on the current patterns of genetic diversity of two southern beeches (Nothofagus nervosa and Nothofagus obliqua) in their eastern fragmented range in ... -
Intensity and number of thinning operations affect the response of Eucalyptus grandis to water availability and extreme drought events
(Elsevier, 2023-02)Climate change has induced an increase in the frequency and intensity of droughts and heat waves, reducing growth and increasing the mortality risk of both natural and planted forests. Management practices are expected to ... -
Latitude, Elevation, and Mean Annual Temperature Predict Peat Organic Matter Chemistry at a Global Scale
(Wiley, 2022-02)Peatlands contain a significant fraction of global soil carbon, but how these reservoirs will respond to the changing climate is still relatively unknown. A global picture of the variations in peat organic matter chemistry ... -
Local adaptation along a sharp rainfall gradient occurs in a native Patagonian grass, Festuca pallescens, regardless of extensive gene flow
(Elsevier, 2020-03)Increasing global aridity combined with changing environmental conditions might cause irreparable alterations in arid and semiarid ecosystems. Knowledge of within-species genetic diversity and adaptive responses, especially ... -
Looking at the forest from below: the role of seedling root traits in the adaptation to climate change of two Nothofagus species in Argentina
(2018-05)Global climate change (CC) is an evolutionary challenge for natural tree populations. Scientific experts forecast an increase in temperature and a decrease in precipitation in the Argentine Patagonian Cordillera. Knowledge ... -
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 ...
