Seasonality, abundance and breeding biology of one of the largest populations of nesting flatback turtles, Natator depressus: Cape Domett, Western Australia

摘要: Cape Domett, located in tropical Western Australia, supports a significant population of flatback turtles, Natator depressus, but the magnitude of this was previously underestimated. We assessed temporal nesting abundance to find that Cape Domett supports one of the largest aggregated nesting flatback turtle populations globally with annual abundance in the order of several thousand individuals (estimated = 3250, 95% CI = 1431–7757). We assessed temporal abundance within a year to find turtles nested throughout the year with peak nesting occurring between August and September. This paper re-evaluates the importance of this major flatback turtle nesting site and shows the first detailed examination of flatback turtle nesting biology in north-western Australia.
