The impact of different natural environments on the regeneration dynamics of two Nothofagus species across elevation in the southern Andes
Cagnacci, Julieta Maria; Estravis Barcala, Maximiliano; Lia, Veronica Viviana; Martinez Meier, Alejandro; Gonzalez Polo, Marina; Arana, María Veronica (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 ... -
Variation of wood density and hydraulic properties of Douglas-fir (Pseudotsuga menziesii (Mirb.) Franco) clones related to a heat and drought wave in France
Dalla Salda, Guillermina; Martinez Meier, Alejandro; Cochard, Hervé; Rozenberg, Philippe (Elsevier, 2009-01)Drought response of three Douglas-fir clones (slow, intermediate and fast growing) inhabiting two different climatic regimes in France was examined.We used the hydraulic conductivity and the percent loss of conductivity ... -
Vegetative propagation of patagonian cypress, a vulnerable species from the subantarctic forest of South America
Aparicio, Alejandro Gabriel; Pastorino, Mario Juan; Martinez Meier, Alejandro; Gallo, Leonardo Ariel (Universidad Austral de Chile, 2009)Increasing risks of loosing forest genetic resources and the need for a sustainable quality wood supply make focusing research efforts on undomesticated tree species necessary. The study of their genetic variation in ... -
What is hot in tree rings? The wood density of surviving Douglas-firs to the 2003 drought and heat wave
Martinez Meier, Alejandro; Sanchez, Leopoldo; Pastorino, Mario Juan; Gallo, Leonardo Ariel; Rozenberg, Philippe (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 ... -
Where to find structural grade timber: a case study in ponderosa pine based on stand and tree level factors
Caballe, Gonzalo; Santaclara, Oscar; Diez, Juan Pablo; Letourneau, Federico Jorge; Merlo, Esther; Martinez Meier, Alejandro (Elsevier, 2020-03-01)Using portable acoustic tools, measurements of dynamic modulus of elasticity (Ed) were made in standing ponderosa pine (Pinus ponderosa (Dougl. ex Laws)) trees (n =437) growing in 22 stands encompassing the range of ... -
Wood density proxies of adaptive traits linked with resistance to drought in Douglas fir (Pseudotsuga menziesii (Mirb.) Franco)
Ruiz Diaz Britez, Manuela; Sergent, Anne Sophie; Martinez Meier, Alejandro; Bréda, Nathalie; Rozenberg, Philippe (Springer, 2014-10)A comparison of dead and surviving Douglas fir trees following the 2003 drought was made to define proxies of adaptive traits for resistance to drought. Increment cores were sampled from trees from three French regions: ...
