Arquitectura del Alerce y del Cipres de las Guaitecas

Abstract

Se analiza la arquitectura y la secuencia de desarrollo de Fitzroya cupressoides (alerce) y Pilgerodendron uviferum (ciprés de las Guaitecas), dos especies endémicas de Cupressaceae, amenazadas y protegidas a nivel internacional, que habitan los sectores más húmedos de los bosques Andino-Patagónicos. Se examina la evolución de la arquitectura de estas dos especies durante los sucesivos estadios desde la germinación hasta la etapa de senescencia, que puede durar varios siglos, mediante el proceso de duplicación o reiteración parcial secuencial. Los efectos del medio ambiente, principalmente debido a traumatismos, afectan sólo cuantitativamente la arquitectura, disminuyendo la velocidad del desarrollo, las longitudes de cada estructura y la importancia de las reiteraciones. Finalmente se señala la utilidad del análisis arquitectural en el estudio de la biología y ecología de las Cupressaceae patagónicas.

This study focuses on the architecture and developmental sequence of Fitzroya cupressoides (alerce) and Pilgerodendron uviferum (ciprés de las Guaitecas), two Cupressaceae species, endemic of southern Chile and Argentina. Both species inhabit the wettest sites of the Andean-Patagonian forests, are considered to be under threat and are protected at international level. The evolution of the architecture of both species through successive stages from germination to senescence, which may extend over several centuries, was investigated by means of the evaluation of duplication and sequential partial reiteration. Environmental factors, mainly in the form of traumatisms, affect only quantitatively the architecture and developmental sequence of these species. The usefulness of the architectural analysis in the study of the biology and ecology of the Patagonian Cupressaceae is highlighted.
