Climatic response of Guadalupe cypress (Hesperocyparis guadalupensis) in Guadalupe island, Baja California, Mexico
A climate-sensitive ring-width chronology of the endemic Guadalupe cypress (Hesperocyparis guadalupensis) was developed for the Guadalupe Island. The chronology length covers the last 205 years (1804-2008) and was significantly correlated (r = 0.45 a 0.48, p<0.000) with ring-width chronologie...

| description | A climate-sensitive ring-width chronology of the endemic Guadalupe cypress (Hesperocyparis guadalupensis) was developed for the Guadalupe Island. The chronology length covers the last 205 years (1804-2008) and was significantly correlated (r = 0.45 a 0.48, p<0.000) with ring-width chronologies from the areas of Baja California, California, and southern Canada formerly used to analyze the influence and for reconstruction purposes of the PDO. This association was weak and non-significant with chronologies developed along the western slopes of the Sierra Madre Occidental, probably influenced by other circulatory patterns. The cypress chronology showed a significant association with instrumental (r= 0.414, P<0.000, n = 109) and reconstructed (r= 0.68 p<0.000, n= 109) indices of the PDO. The chronology was significantly associated (r= 0.65, p<0.0005, n= 44) with the January-November precipitation for weather stations in Ensenada indicating potential for climate reconstructions. The spectral analysis of the ring-width chronology detected significant peaks at frequencies from 12 to 28 years and 50 to 70 years which are associated to the PDO effect, and peaks of 6.8 more related to the ENSO effect. The location of the chronology at the southern extreme of the PDO influence area may be important to analyze in greater detail the impact of the PDO and other atmospheric phenomena such as ENSO. The observed climatic response of cypress opens new research opportunities for paleoclimatic studies and may be useful to plan for restoration and conservation actions of this and other associated species. |

Una serie dendrocronológica climáticamente sensitiva de anillo total se desarrolló en Isla Guadalupe con la especie endémica ciprés de Guadalupe (Hesperocyparis guadalupensis (S. Watson) Bartel. Var. guadalupensis). La cronología comprende los últimos 205 años (1804-2008) y mostró una respuesta significativa (r = 0.45 a 0.48, p<0.0001) con cronologías de anillos de árboles procedentes de Baja California, California y Sur de Canadá, utilizadas para análisis del impacto y reconstrucción del PDO. No obstante, esta asociación fue débil con cronologías desarrolladas en la Sierra Madre Occidental, que probablemente estén influenciadas por otros fenómenos circulatorios. Se encontró una respuesta significativa con registros instrumentales (r= 0.414, p<0.0001, n = 109) y reconstruidos (r= 0.68 p<0.0001, n= 109) del PDO. La cronología se asoció significativamente con la lluvia enero-noviembre de Ensenada (r= 0.65, p<0.0005, n= 44), indicando potencial para reconstrucciones de clima. El análisis espectral de la serie dendrocronológica detectó la presencia de frecuencias significativas de 12 años a 28 años y de 50 años a 70 años, que se relacionan con el PDO; mientras que la frecuencia significativa de 6.8 años pudiera estar relacionada con ENSO. Dado que la cronología se ubica en el extremo más al sur de la influencia del PDO, esta puede ser de utilidad para determinar el área de influencia de este fenómeno y el posible impacto de otros como ENSO. La respuesta climática encontrada con esta especie, abre oportunidades para nuevas investigaciones paleoclimáticas, que a la vez son importantes para promover acciones de restauración de ecosistemas y la conservación de esta y de otras especies asociadas.
