• Analyse rétrospective de l’adaptation à la sécheresse chez le douglas 

      Rozenberg, Philippe; Sergent, Anne Sophie; Dalla Salda, Guillermina; Martinez Meier, Alejandro; Marin, Sara; Ruiz Diaz, Manuela; Bastien, Jean-Charles; Sanchez, Leopoldo; Bréda, Nathalie (Swiss Forestry Society and Allen Press, 2012-03)
      For a number of years in certain regions of France the Douglas-fir trees (Pseudotsuga menziesii [Mirb.] Franco) have presented symptoms of withering which have been attributed to drought. Our results show that the hydraulic ...
    • Assessment of resistance to xylem cavitation in cordilleran cypress using near-infrared spectroscopy 

      Sergent, Anne Sophie; Segura, Vincent; Charpentier, Jean-Paul; Dalla Salda, Guillermina; Fernandez, María Elena; Rozenberg, Philippe; Martinez Meier, Alejandro (Elsevier, 2020-04)
      Characterizing drought resistance of forest trees is an important aim in the worldwide context of increasing forest decline and dieback. Furthermore, wood demand is increasing all around the world, urging the need for the ...
    • Climate warming differently affects Larix decidua ring formation at each end of a French Alps elevational gradient 

      Rozenberg, Philippe; Chauvin, Thibaud; Escobar-Sandoval, Margarita; Huard, Frédéric; Shishov, Vladimir; Charpentier, Jean-Paul; Sergent, Anne Sophie; Vargas-Hernandez, José Jesus; Martinez Meier, Alejandro; Pâques, Luc (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: ...
    • Does competition management improve the ecophysiological response to water shortage of mixed woodland species of North Patagonia? 

      Varela, Santiago Agustin; Diez, Juan Pablo; Letourneau, Federico Jorge; Bianchi, Emilio; Weigandt, Mariana Noemi; Porté, A.J.; Sergent, Anne Sophie; Nacif, Marcos E.; Garibaldi, Lucas Alejandro; Fernandez, María Elena (Elsevier, 2023-08)
      Globally, the increasing forests vulnerability and drought-induced forest mortality events, extended to a larger scale, may have the potential to rapidly alter forest functioning and the provision of ecosystem services. ...
    • Dynamics of cavitation in a Douglas-fir tree-ring: transition-wood, the lord of the ring? 

      Dalla Salda, Guillermina; Fernandez, María Elena; Sergent, Anne Sophie; Rozenberg, Philippe; Badel, Eric; Martinez Meier, Alejandro (INRA, 2014-11)
      The objective of this work wa s to investigate the dynamics of embolism formation within a Douglas fir tree ring . Four resistant and four vulnerable 10 year old trees were selected among 50 trees, based on their P 50 . ...
    • Receta práctica paso a paso para construir dendrómetros de punto de bajo costo 

      Diez, Juan Pablo; De Paz, Manuel; Varela, Santiago Agustin; Dalla Sald, Guillermina; Sergent, Anne Sophie; Martinez Meier, Alejandro (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 ...
    • 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: ...
