Morphometric Measurements of Teira Dugesii Lizards Across the Madeira Archipelago

375 adult individuals of the lizard Teira dugesii were measured across nine localities in the Madeira and Selvagens Islands. José Câmara collected data during the summers of 1995–1998 using a consistent, non-invasive capture-and-release protocol. The dataset records nine linear head measurements and Snout–Vent Length for each individual, representing four recognized subspecies.

Use Cases

• Investigate insular morphological variation based on measurements from multiple islands.
• Analyze sexual dimorphism patterns based on morphometric data from adult individuals.
• Study population differentiation across subspecies based on geographic sampling.
• Establish a morphological baseline for future temporal analyses assessing change over time.

Strengths

• Includes 375 adult individuals, providing a substantial sample size for analysis.
• Covers nine localities across multiple island groups, offering broad geographic representation.
• Data collection followed a consistent protocol over four summers (1995–1998), promoting comparability.
• Represents the four currently recognized subspecies of Teira dugesii.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment for some statistical methods.
• Data collection occurred over 25 years ago; contemporary relevance may require verification.
