Antecedentes del Sirex noctilio (Hymenoptera-Siricidae) en el Valle de Calamuchita, Córdoba, Argentina

Abstract

The nesting sites of hawksbill and green turtles from Indonesia were examined. Effective diameter and coefficient uniformity of their sand nest were calculated. Color of sand nest and profiles of beaches were identified. The main materials were composed mostly of coral sand and sometimes mixed with shells or roots. These were probably the influencing factors for these species in choosing suitable place for spawning. Although green turtle had nearly the same requirement for heterogenous material composition for their nesting sites as it was for the hawskbill, the topography of flat beaches is required by the green sea turtles nesting in Indonesia.
