Seasonal Variation of Carabid Beetle (Coleoptera : Carabidae) Abundance and Diversity in Ranomafana National Park, Madagascar

Johanna Rainio

Seasonal variation in arthropod abundances is observed in many tropical forests all over the world. This study examines seasonal occurrence of carabid beetles in Ranomafana National Park, Madagascar, where little research has been done concerning seasonality of arthropods. Carabid beetles were collected from secondary and primary montane rainforests throughout a one year. In total, 1205 individuals of 50 species were collected. During the year there was a considerable variation in the abundances of carabids. The highest number of individuals was collected in February, which is a warm and rainy month while the lowest numbers were obtained in May, which is in the beginning of drier months. Species composition varied considerably during the year, 28% of the species were found only in one month, and only one species was collected in every sampling month. For total species inventory at least one year of collecting is then recommended.
