CARACTERÍSTICAS CLIMÁTICAS, MORFOMÉTRICAS Y ESTRUCTURALES DE POLYLEPIS RUGULOSA BOSQUES AMARGOS EN LAS LADERAS ÁRIDAS DEL SUROESTE DE LOS ANDES EN LA REGIÓN DE MOQUEGUA - PERÚ
Contenido principal del artículo
Resumen
El propósito del estudio es caracterizar los patrones de preferencia de las especies por factores físicos para ayudar a los gestores locales y regionales a identificar áreas adecuadas para la conservación, gestión y restauración. El diseño del estudio se basa en tres preguntas principales: (i) ¿Qué tan influyentes son factores como la pendiente, el cercamiento del valle, la proximidad a los recursos de agua subterránea y la exposición a la radiación en variables estructurales forestales como la densidad, los patrones de distribución y el tamaño de los árboles? (ii) ¿Es posible identificar patrones de regeneración o reclutamiento que estén influenciados por la altitud, topografía, morfometría o clima? Por último, (iii) ¿podría este patrón desagregado ser una característica natural de los bosques de Polylepis en la región de Moquegua? Tras definir las características generales del clima y la morfometría, se utilizó el análisis Ripley K para identificar patrones de ordenación estructural en 36 parcelas (50 x 50 m) distribuidas en seis sitios distintos a lo largo de la distribución forestal. Estos patrones concentrados se asociaron con diferencias de densidad entre plantas adultas y juveniles según la altitud: mientras que la abundancia total de árboles disminuye con la altitud, la abundancia de árboles juveniles aumenta. Este patrón de cambio de actividad a mayor altitud puede estar influenciado por el cambio climático, pero se requieren investigaciones adicionales para confirmar o refutar esta hipótesis
