| White, S. A. 2002. A mist-netting study in Guayaguayare and the Victoria Mayaro Forest Reserve, Trinidad, West Indies Department of Life Sciences, University of the West Indies, St. Augustine, Occasional Paper 11:111-118. ABSTRACT.--During July-August 1999, I conducted a mist-netting study of resident landbirds in four different forest types in southern Trinidad, West Indies: (1) virgin forest; forest managed by the (2) Open Range Method (ORM) and (3) Periodic Block System (PBS); and (4) mixed forest. During 728 mist net hrs, 742 individual birds representing 57 species were captured at the four sites. Species richness, species diversity and capture rates were greatest in the mixed forest and lowest in the virgin forest. The avifauna of the PBS forest most closely resembled that of the virgin forest. However, given the limitations of mist-netting, further censuses are needed to adequately compare avifaunal composition between the four sites. RESUMEN.--Durante julio-agosto de 1999, estudie las aves terrestres con redes de niebla en cuatro diferentes tipos de bosque en el sur de Trinidad, Indias Occidentales: (1) bosque virgen; bosque manejado por el (2) M�todo Rango Abierto (MRA) y (3) Sistema de Bloque Peri�dico (SBP); y (4) bosque mixto. Durante 728 hr de red de niebla, se capturaron 742 individuos de 57 especies en los cuatro sitios. La riqueza de especies, diversidad de especies y tasa de captura fueron m�s altos en el bosque mixto y m�s bajo en el bosque virgen que en cualquier otro sitio. La avifauna del bosque SBP fue m�s similar a la del bosque virgen. Sin embargo, dado a las limitaciones en el uso de las redes de niebla, se requieren m�s censos para comparar adecuadamente la composici�n de aves entre los cuatro sitios. KEY WORDS.--bird populations, forest management, mist-netting, species diversity, species richness, Trinidad |
