dc.description.abstract | [eng] We describe the spatial distribution of tree height of Pinus uncinata at two undisturbed altitudinal treeline ecotones in the southern Pyrenees (Ordesa, O, and Tessó, T). At each site, a rectangular plot (30 x 140 m) was located with its longest side parallel to the slope and encompassing treeline and timberline. At site O, height increased abruptly going downslope with a high spatial autocorrelation at short distances. In contrast, the changes of tree height across the ecotone at site T were gradual, and tree height was less spatially autocorrelated. These results can be explained by the greater importance of wind and snow avalanches at sites O and T, respectively. | - |
dc.description.abstract | [spa] Describimos la distribución espacial de la altura de individuos de Pinus uncinata en dos ecotonos del límite del árbol localizados en los Pirineos meridionales (Ordesa, O; Tessó, T). En cada sitio, situamos una parcela rectangular (30 x 140 m) con su lado mayor paralelo a la pendiente e incluyendo los límites altitudinales del árbol y del bosque. En el sitio O, la altura aumentó de forma brusca al descender en altitud mostrando una elevada autocorrelación espacial a pequeñas distancias. Por contra, los cambios de altura en el ecotono del sitio T fueron graduales, mostrando esta variable menor autocorrelación. Estos resultados pueden explicarse por la mayor importancia del viento en el sitio O y de los aludes de nieve en el sitio T. | - |
