Bird Heat and Hydric Stress Metrics Across Vegetation States in Australian Mallee

506.3 KB of data integrates vegetation mapping, microclimate simulations, and species-specific biophysical models to quantify heat and dehydration risk for birds. The repository contains morphological parameters, plumage measurements from museum specimens, validation data from lab studies, and hourly temperature records from field loggers. Authored by Rodolfo Cesar de Oliveira Anderson and last updated on 2026-04-21, it provides a spatially explicit framework for identifying climate refuges in semi-arid ecosystems.

Use Cases

• Modeling species-specific heat stress under +4 °C climate scenarios based on integrated biophysical models.
• Assessing the buffering capacity of structurally intact vegetation on physiological stress based on microclimate simulations.
• Validating microclimate models using hourly air temperature records from iButton loggers across six vegetation states.
• Prioritizing conservation actions by identifying climate refuges based on spatially explicit stress metrics.

Strengths

• Includes original plumage measurements taken from museum specimens for parameterizing feather insulation.
• Contains data from published laboratory studies used for model validation.
• Hourly air temperature records from field-deployed iButton loggers across six distinct vegetation states.
• All R scripts for modeling, validation, sensitivity, and statistical analysis are provided.

Limitations

• Row count is unknown, which may limit suitability assessment.
• Column-level documentation is absent; field semantics must be inferred after download.
• Data is limited to a specific heterogeneous landscape in the Australian Mallee, which may affect generalizability.
