Abstract

Abstract: The silvery gibbon (  Hylobates moloch), endemic to the island of Java, relies on closed-canopy, lowland evergreen forest for its survival. Because Java has lost over 91% of its original forest, silvery gibbons currently occupy small, isolated forest fragments and are threatened with extinction. To contribute to a comprehensive conservation strategy for this species, we analyzed the mtDNA control region of 31 silvery gibbons representing most remaining populations. Our results suggest the presence of at least two genetically differentiated lineages: a “western” lineage, represented by the largest remaining natural population in Gunung Halimun National Park and a “central” lineage, consisting of smaller, more isolated populations in and around the Gunung Masigit/Simpang/Tilu complex, Gunung Gede/Pangrango, and Gunung Slamet. These two lineages, at a minimum, represent different management units that should, except in the most dire circumstances, be managed separately.

Abstract

Resumen: El gibón plateado (  Hylobates moloch), endémico a la isla de Java, depende de un dosel cerrado del bosque compacto siempre-verde para su supervivencia. Debido a que Java a perdido cerca de un 91% de su bosque original, los gibones plateados actualmente ocupan fragmentos de bosque pequeños y aislados y están amenazados de extinción. Para contribuir con una estrategia de conservación comprensiva de esta especie, analizamos la región de control del ADNm de 31 gibones representantes de la mayoría de las poblaciones remanentes. Nuestros resultados sugieren la presencia de al menos dos linajes genéticamente diferenciados: el linaje “occidental” representado por la población natural remanente más grande en el parque nacional Gunung Halimun y un linaje “central” consistente de poblaciones pequeñas más aisladas en y alrededor del complejo Gunung Masigit/Simpang/Tilu, Gunung Gede/Pangrango y Gunung Slamet. Estos dos linajes por lo menos representan unidades de manejo diferentes que deberían ser manejadas por separado, excepto bajo las más desastrosas circunstancias.
