Boosting female hatchling production in endangered, male-biased turtle populations
In turtle species with temperature-dependent sex determination, hatchling sex ratios skewed toward males could threaten populations where females are vulnerable to harvest. We tested the efficiency of black plastic covers in producing more female hatchlings from nests of the six-tubercle Amazon Rive...

In turtle species with temperature-dependent sex determination, hatchling sex ratios skewed toward males could threaten populations where females are vulnerable to harvest.

Covered nests produced 37% more females and midnest average temperatures were 1° C higher than control nests.
