Abstract

The changes of the Coleopterofauna in a Pinus pinaster forest, Zamora province (Spain), have been determined after a wild fire in June 1996. Sampling was carried out from April to October 1997 in the burnt area and in a nearby unbumt control pine forest. Pitfall traps containing three different types of attracting bait were placed in each area at different distances from the firebreak. Greater abundance was recorded for the liver baits, followed by the beer and water, respectively, in both the burnt and control pine forests. Results indicated that the Coleopterofauna colonizing the burnt forest were more oportunistic and a greater specific richness were observed in the burnt area such as Histeridae, Silphidae, Carabidae and Scarabaeidae.

Abstract

El objetivo de este trabajo es determinar los cambios producidos en la Coleopterofauna tras un incendio natural ocurrido en junio de 1996 en un pinar de Pinus pinaster de la provincia de Zamora (Espana). Para ello se han realizado muestreos de Abril a Octubre de 1997 en la zona quemada y en una zona control pröxima de pinar no quemado. Se dispusieron en cada una de las zonas elegidas, baterias de trampas pitfall con très tipos de cebos atrayentes y a diferentes distancias del cortafuegos. En ambas zonas de muestreo, las trampas de higado capturaron mayor numéro de especimenes seguidas de las trampas de cerveza y, finalmente las de agua. Los resultados indicaron que la Coleopterofauna recolonizadora del pinar quemado presentô una mayor riqueza especîfica con especies mas oportunistas de las familias Histeridae, Silphidae, Carabidae and Scarabaeidae.
