Development of native and exotic woody species in the Patagonian cypress forests. The growth and architecture of forest-dwelling woody plants affect the dynamics of these communities. The present study was aimed at improving our understanding of the dynamics of Argentinean Austrocedrus chilensis forests through the study of length growth and architecture of some of the most frequent native and exotic woody species in these communities (natives: Aristotelia chilensis, Berberis microphylla, Lomatia hirsuta, Maytenus boaria, Myoschilos oblongum and Schinus patagonicus; exotics: Juniperus communis, Prunus avium, Pseudotsuga menziesii and Rosa rubiginosa). During the study period (20122014), the length growth of the main axis was not necessarily related to the height growth of labeled plants. Reductions in height were found for individuals of all species but P. menziesii and P. avium, which are exotics in Patagonia. The majority of plants presented notable deviations of the main axis from the vertical; the extent of this deviation was negatively correlated with both the length of the distal main-axis shoot and the height variation of the plant. The species under survey may be categorized in four functional groups according to their architecture. The invasion of these cypress forests by exotic species such as P. menziesii y P. avium, which belong to functional groups different from those of the most frequent coexisting native species, may promote the competitive replacement of native species by exotic species. |

Brote anual arquitectura grupos funcionales invasiones eje principal reiteración Development of native and exotic woody species in the Patagonian cypress forests.

The species under survey may be categorized in four functional groups according to their architecture.

El crecimiento y la arquitectura de las especies leñosas que habitan los bosques inciden en la dinámica de estas comunidades. El objetivo principal de este estudio fue mejorar la comprensión de la dinámica de los cipresales patagónicos a partir del análisis del crecimiento longitudinal y de la arquitectura de las especies leñosas más abundantes en esas comunidades, las nativas: Aristotelia chilensis, Berberis microphylla, Lomatia hirsuta, Maytenus boaria, Myoschilos oblongum y Schinus patagonicus; y las exóticas: Juniperus communis, Prunus avium, Pseudotsuga menziesii y Rosa rubiginosa. El crecimiento longitudinal del eje principal no se relacionó necesariamente con el aumento en altura de las plantas durante el período de estudio (2012-14). Se registraron decrecimientos en altura en todas las especies excepto en P. menziesii y P. avium, exóticas para Patagonia. La mayoría de los individuos presentaron notables desviaciones de su eje principal de la vertical, las que se correlacionaron negativamente con la longitud del brote distal y con la variación en altura de las plantas. Se agruparon las especies en cuatro grupos funcionales, de acuerdo a su arquitectura y crecimiento. La invasión de los cipresales por parte de especies exóticas como P. menziesii y P. avium, asociadas a grupos funcionales distintos a los de las especies nativas más frecuentes, podría impactar significativamente en la dinámica de esas comunidades promoviendo el reemplazo de las especies nativas por las exóticas dominantes.
