    Fine-scale satellite-based monitoring of temperature and vegetation cover in microclimates, distribution ranges, and landscape connectivity for Neurergus kaiseri (Kaiser’s mountain newt) during the breeding season by Peyman Karami, Sajad Tavakoli, Mina Esmaeili

    Published 2025-01-01
    “…However, a gap remains in monitoring time-specific environmental indicators using fine-scale satellite remote sensing (SRS). This study integrates spatiotemporal indicators with fine-scale SDMs to provide insights into Neurergus kaiseri’s response to vegetation cover and temperature changes during the breeding season, informing conservation and management strategies.Data on localities, habitat suitability, and population cores connectivity from Karami et al. (2024) were divided into five sub-basins in Iran. …”
