Can nesting behaviour allow reptiles to adapt to climate change?

Area of Science:

• Ecology
• Evolutionary Biology
• Herpetology

Background:

• Abiotic factors in reptile nests critically influence hatchling viability, sex, behavior, and size.
• Reproducing female reptiles strategically manipulate nest conditions (timing, location, depth) to control offspring phenotypes.

Purpose of the Study:

• To explore how nesting reptiles modify behaviors in response to environmental gradients.
• To investigate the impact of climate change on reptile nest environments and embryonic development.
• To identify research priorities for understanding maternal nesting responses to climate change.

Main Methods:

• Observational studies on nesting reptile behavior across spatial and temporal gradients.
• Analysis of how maternal nesting strategies influence nest temperature and soil moisture.
• Literature review to synthesize current understanding and identify knowledge gaps.

Main Results:

• Maternal nesting behaviors significantly affect nest thermal and hydric conditions, influencing embryonic development and vulnerability.
• Climate change poses a substantial threat by altering nest environments, potentially impacting hatchling phenotypes and survival rates.
• Female reptiles exhibit adaptive nesting plasticity to buffer against climate-related impacts, though the extent and consequences are not fully understood.

Conclusions:

• Further research is essential to document climate-induced nest environment changes and quantify the effectiveness of maternal behavioral buffering.
• Understanding the ecological and evolutionary consequences of maternal nesting responses to climate change is critical for reptile conservation efforts.
• Limited understanding of reptile nesting behaviors under climate change necessitates focused future studies.
