Título: | Earlywood and Latewood Widths of Picea chihuahuana Show Contrasting Sensitivity to Seasonal Climate |
Autor: | Cabral-Alemán, Citlalli; Pompa-García, Marín; Acosta-Hernández, Andrea C.; Zúñiga-Vásquez, José M.; Camarero, Jesús Julio CSIC ORCID | Fecha de publicación: | 18-may-2017 | Editor: | Multidisciplinary Digital Publishing Institute | Citación: | Forests 8 (5): 173 (2017) | Resumen: | The existence of endangered tree species in Mexico necessitates an understanding of their vulnerability to the predicted climate changes (warming and drying trends). In this study, the sensitivity to climate of earlywood (<i>EW</i>) and latewood (<i>LW</i>) widths of the threatened <i>Picea</i> <i>chihuahuana</i> was determined. The response of <i>EW</i> and <i>LW</i> to climate variables (maximum temperature, minimum temperature, precipitation, evaporation, and a drought index) was analyzed by means of correlation analysis using dendrochronology over the period of 1950–2015. <i>EW</i> and <i>LW</i> production were enhanced by cool and wet conditions during winter prior to the start of growing season. During the growing season, <i>EW</i> and <i>LW</i> production increased in response to cool spring and summer conditions, respectively; temperatures and year-round evaporation, excluding summer and the previous drought in the period prior to the growing season. <i>EW</i> was sensitive to seasonal drought, which is a concern considering the predicted aridification trends for the study area. These results provide further knowledge on the dendroecological potential of <i>Picea chihuahuana</i>. | Versión del editor: | https://doi.org/10.3390/f8050173 | URI: | http://hdl.handle.net/10261/154373 | DOI: | 10.3390/f8050173 | Identificadores: | doi: 10.3390/f8050173 |
