Gymnodactylus amarali Climate Vulnerability Analysis with SDMs and Biophysical Models

A study projects Gymnodactylus amarali, a nocturnal lizard from the Brazilian Cerrado, will lose over 96% of its climatically suitable range by the end of the century. The research combines correlative, mechanistic, and hybrid species distribution models with biophysical simulations to assess range dynamics and thermal constraints. Authored by Ticiane de Lima Costa and last updated in May 2026, the dataset is shared under a CC-BY-4.0 license.

Use Cases

• Projecting species range shifts based on climate change scenarios mentioned in the description
• Analyzing thermal activity constraints for nocturnal ectotherms based on biophysical model outputs
• Prioritizing conservation areas for rocky habitat specialists using stable range area metrics
• Comparing correlative and mechanistic modeling approaches for species vulnerability assessments

Strengths

• Integrates multiple modeling approaches (correlative, mechanistic, hybrid SDMs) for a comprehensive assessment
• Provides specific projections, including a >96% range loss and a >50% decline in annual activity hours
• Focuses on an understudied taxonomic group (nocturnal reptiles) in a threatened biome (Brazilian Cerrado)

Limitations

• Dataset scale is limited to a single species (Gymnodactylus amarali) and a 37.6 KB document
• Column-level documentation is absent; field semantics must be inferred after download
• Row count is unknown, which may limit suitability assessment
