Coleópteros saproxílicos en bosques mediterráneos de Chile: primeros pasos hacia su conocimiento y conservación

Alejandra García López

Resumen

Los ecosistemas mediterráneos han sido reconocidos como prioridad para la conservación de la biodiversidad debido a sus elevados niveles de riqueza de especies y endemismos. En Sudamérica estos ecosistemas se encuentran restringidos al área central de Chile y representan un hotspot de biodiversidad. La riqueza y abundancia de especies de los coleópteros saproxílicos en esta área es un tema inexplorado, pese a la función ecológica del grupo en los ecosistemas y su potencial en el monitoreo del grado de conservación de los bosques. El presente estudio subraya la importancia de los coleópteros saproxílicos en los bosques mediterráneos chilenos. Estos ecosistemas se caracterizan por una elevada heterogeneidad de vegetaciones y por la presencia de zonas fragmentadas que rodean las áreas protegidas y que presentan distintos grados de transformación. El trabajo pone de manifiesto la importancia de preservar los árboles nativos añosos en esas áreas fragmentadas, los cuales ayudan al mantenimiento de la biodiversidad y presentan un elevado valor en la conservación de la fauna saproxílica.
