Abstract

Increasing nest temperatures associated with climate change are anticipated to adversely impact sea turtle populations. Here, I parameterized and integrated mechanistic models of nest temperature with data collected on embryonic development rates and sex ratios, to explore how climate change will impact green and flatback turtles nesting in Western Australia. I showed winter nesting adapted populations were particularly threatened by climate change, due to their inability to shift nesting phenology to avoid suboptimal sand temperatures. Using a transcriptomic approach, I demonstrated that loggerhead turtle embryos regulate 179 genes involved with stress response and developmental pathways when exposed to sub-lethal temperatures.
