Altitudinal distribution and phenology of three species of carrion beetles(Coleoptera : Silphidae) from Nevado de Colima, Jalisco, Mexico

摘要

The taxonomy of carrion beetles (Coleoptera: Silphidae) from M6xico was revised by Peck, S. B. & R. S. Anderson (1985. Quaest. Ent., 21(3): 247-317) who recorded eleven species belonging to four genera. Other contributions, especially for Jalisco State include: Volcan de Tequila (Navarrete-Heredia, J. L. 1995. Dugesiana, 2(2): 11-26); Sierra de Manantlfin (Rivera-Cervantes, L. E. & E. Garcia-Real. 1998. Dugesiana, 5(1): 11-22), and La Primavera and Barranca del Rio Santiago (Navarrete-Heredia, J. L. & H. E. Fierros-L6pez. 1998. Dugesiana, 5(1): 49-50). This study was done in Jalisco by staff members from the Center for Zoological Research, University of Guadalajara to determine carrion beetle distribution. In this note, we describe our trapping results from the National Park Nevado de Colima, Jalisco, M6xico. Field work was done on the NW slope of the National Park Nevado de Colima, in the locality El Floripondio, Cerro Las Vioras, San Gabriel County, between 2200-3000 meters above sea level (m). We used carrion traps (model NTP-80) designed by Mor6n, M. A. & R. Terr6n [1984. Acta Zool. Mex. n.s., (3): 1-47]. Six sites were selected: Cupressus forest (2300 m), oak-pine forest (2400 m), cloud forest (2600 m), Abies forest (2840 m), disturbed Abies forest (2920 m), and Abies-grass association (2950 m). One carrion trap was used for each site during one month, starting in April and ending in October 1998. Rotting squid was used as bait.
