Abstract :

We surveyed the small mammals of remnant mixed hardwood-coniferous cloud forest at elevations ranging from 2,100-2,300 m in the Chelemha Cloud Forest Reserve, Alta Verapaz, Guatemala. Removal-trapping using a combination of live traps, snap traps, and pitfall traps for 6 days in January 2007 resulted in 175 captures of 15 species of marsupials, shrews, and rodents. This diversity of small mammals is the highest that we have recorded from a single locality of the 10 visited during eight field seasons in the highlands of Guatemala. Based on captures, the most abundant species in the community of small mammals is Peromyscus grandis (n = 50), followed by Handleyomys rhabdops (n = 27), Heteromys desmarestianus (n = 18), Reithrodontomys mexicanus (n = 17), Handleyomys saturatior (n = 16), Sorex veraepacis (n = 15), and Scotinomys teguina (n = 13). The remaining eight species were represented by one to five individuals. Se realizo un inventario de mamiferos pequenos en el remanente bosque mixto de latifoliadas y coniferas de la Reserva Chelemha, AltaVerapaz, Guatemala. El muestreo se realizo a elevaciones desde 2,1002,300 m en el bosque nuboso de la Reserva. Se removieron los mamiferos capturados con una combinacion de trampas de captura viva, trampas de captura muerta, y trampas de caida durante 6 dias en enero del 2007. Se obtuvieron 175 capturas que representan 15 especies de marsupiales, musaranas y roedores. Esta diversidad de mamiferos pequenos es la mas alta que hemos registrado en una sola localidad de 10 sitios visitados durante ocho temporadas de campo en las tierras altas de Guatemala. Con base a las capturas, las especies mas abundantes en la comunidad de pequenos mamiferos fueron Peromyscus grandis (n = 50), seguida de Handleyomys rhabdops (n = 27), Heteromys desmarestianus (n = 18), Reithrodontomys mexicanus (n = 17), Handleyomys saturatior (n = 16), Sorex veraepacis (n = 15), y Scotinomys teguina (n = 13). Las restantes ocho especies fueron representadas por uno a cinco individuos.
