Trialling seawater irrigation to combat the high nest temperature feminisation of green turtle Chelonia mydas hatchlings
- Description:
- Global increases in beach sand temperatures are predicted to skew hatchling sexratios of marine turtle populations towards female bias. Currently, shade structures and fresh-water irrigation are management strategies used to cool nest temperatures, but require resources that are limited at remote rookeries. Here, we report on a novel investigation that used seawater irrigation as a sand-cooling method. Various volumes of seawater were applied to sand to deter-mine the optimal application required to lower sand temperatures at nest depth to produce male-biased sex ratios.
