The impact of timber exploitation on biodiversity is usually increased by hunting in the exploited area. Proper forest management practices on areas under commercial exploitation minimize hunting and damage to the forest. Large species of Cracidae, the most endangered family of birds in the Neotropics, are among the first to be affected in a Neotropical forest damaged by timber-extraction activities, and where at least moderate hunting occurs. Herein an assessment of cracids is carried out in three areas with selective logging in Peru in 2004 and 2005, is used to evaluate hunting pressure. Tree inventory trails were used as transects, and density was calculated using the line transect methodology. Four species of cracids were evaluated, and density was calculated for three of them. The area with lower hunting pressure, Maderyja, showed higher cracid diversity and was the only with the pr...

This study analyzes the probabilities of survival for a population of tarukas (Cervidae: Hippocamelus antisensis) in southern Peru using data gathered in the fi eld, data from other studies and the computer-based Vortex simulation program. A total of 900km2 of the northern part of the Aymara- Lupaca Reserved Zone were evaluated in 1997. The population viability analysis showed that this taruka population exhibited a high sensitivity to changes in fi rst-year mortality, immigration and fragmentation of the population. Taruka population size and survival probabilities did not exhibit sensitivity to changes in the carrying capacity of the area or to changes in environmental variation. Although the results of this study are open to alternative interpretation, the conservation and management of taruka in the Aymara-Lupaca Reserved Zone may be helped by the fi ndings of the viability analysis....

Se analiza las probabilidades de supervivencia de una población de tarukas (Cervidae: Hippocamelus antisensis) en el sur del Perú usando datos obtenidos en el campo, datos de otros estudios y el programa informático de simulación Vortex. Un total de 900 km2 de la sección norte de la Zona Reservada Aymara Lupaca fueron evaluados en 1997. El análisis de viabilidad poblacional mostró que esta población de tarukas es altamente sensible a cambios en la mortalidad del primer año, inmigración y fragmentación de la población. El tamaño de la población y las probabilidades de supervivencia no mostraron sensibilidad a cambios en la capacidad de carga del área o en la variación medioambiental. Los resultados de este estudio están abiertos a otras alternativas de interpretación, sin embargo la conservación y manejo de la población de tarukas en la Zona Reservada Aymara Lupaca pue...
