ALTAMIRANDA SAAVEDRA, Mariano. DRAGONFLY (INSECTA: ODONATA) DIVERSITY IN TWO USE OF SOILS IN A TROPICAL DRY FOREST. Rev. Fac. Nac. Agron. Medellín [online]. 2009, vol.62, n.2, pp.5071-5079. ISSN 0304-2847.
Dragonfly diversity was estimated in the Agricultural Center Cotové (Santafé de Antioquia-Colombia). Active capture using an entomological net was used. Each transect was located perpendicular to the water body, for a length of approximately 200 m and a lateral extension of 8 m. Twenty Odonata species were registered, from 5 families and 15 genus. Libellulidae showed the biggest abundance and richness, with 65 specimens that represent 53.7% of the total abundance, and 12 species that represent 60% of the registered community. The α diversity was high in the forest in reference at crop; however, the low abundances register highlight the need for greater sampling effort in cultivating, for a better estimate of γ diversity; the β diversity was of 12 species and the complementary index was of 0.6, it indicates that the Odonata's fauna is characteristic and distinctive for each use of soil.
