Arid and semiarid rangeland responses to non-stationary temporal dynamics of environmental drivers
(Elsevier, 2022-08)Temporal ecology is a growing research field aimed at understanding how temporal dynamics structure ecological systems in a changing environment. Ecosystems are exposed to accelerating environmental changes —mainly driven ... -
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: ... -
Genetic control of the tree-ring response of Douglas-fir (Pseudotsuga menziesii (Mirb.) Franco) to the 2003 drought and heat-wave in France
(Springer, 2008)The genetic control of tree ring growth in Douglas-fir in response to the drought and heat-wave that occurred in 2003 in Europe was studied with microdensity profiles in three clonal experiments located in three different ... -
Heritable variation in the survival of seedlings from Patagonian cypress marginal xeric populations coping with drought and extreme cold
(Springer, 2012-01)The rear edges of tree species have begun to be perceived as highly valuable for genetic resources conservation and management. In view of expected climatic changes, the responses of trees at their xeric limits may largely ... -
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 ... -
Maqui (Aristotelia chilensis [Mol.] Stuntz) morphological and phenolic traits associated with forests type and latitudinal gradient in natural populations of Patagonia Argentina
(Elsevier, 2021-12)Maqui (Aristotelia chilensis [Mol.] Stuntz) is a native berry of the Patagonia Andean forests, which has one of the highest antioxidant levels currently known. This biochemical characteristic strongly depends on the phenolic ... -
Phenotypic plasticity of European larch radial growth and wood density along a-1,000 m elevational gradient
(Wiley, 2021-02)Phenotypic plasticity is a key mechanism for sedentary long-living species to adjust to changing environment. Here, we use mature Larix decidua tree-ring variables collected along an elevational transect in the French Alps ... -
Strains in Sustainability Debates: Traditional Ecological Knowledge and Western Science through the Lens of Extension Agents in a Pastoral Region
(Wiley Online Library, 2020-03)Those involved in sustainability debates on developmental pathways concur in the synergistic potential of integrating traditional ecological knowledge (TEK) and Western scientific approaches. Transhumant pastoralism is a ... -
What is hot in tree rings? The wood density of surviving Douglas-firs to the 2003 drought and heat wave
(Elsevier, 2008-08)In a global warming scenario, drought and heat waves like the one that occurred in 2003 in Europe are expected to become more intense and frequent. This extreme climate event strongly affected the hydraulic balance in many ...
