  • 1

    Introduces the webinar's focus on mapping habitat suitability and connectivity.

  • 2

    Highlights the importance of ecological tools for transport planning.

  • 3

    Sets the stage for practical demonstrations using MaxEnt and Circuitscape.

Fundamentals of Geographic Information Systems (GIS), including working with raster datasets, ASCII grid formats, and spatial coordinate systems.
Basic concepts of Landscape Ecology, specifically habitat fragmentation, core habitat patches, and the difference between structural and functional connectivity.
Principles of Species Distribution Modeling (SDM), particularly how environmental covariates (like elevation, land cover, and distance to water) are used to predict habitat suitability.
The theoretical foundation of Electrical Circuit Theory as applied to ecology, where landscapes are treated as conductive surfaces and wildlife movement is modeled as electrical current.
Advanced omnidirectional connectivity modeling using Omniscape to analyze movement without pre-defined source and destination points.
Field validation techniques, such as using GPS telemetry collar data or camera trap arrays to ground-truth modeled wildlife corridors.
Landscape Genetics, integrating genetic flow data of target populations to empirically validate and refine resistance surfaces.
Applied Road Ecology engineering, including the systematic selection and design of wildlife crossings (overpasses and underpasses) and fencing based on connectivity maps.

This webinar demonstrates how to use Maxent software to model habitat suitability by establishing relationships between species occurrence data and environmental variables (such as altitude, land use, hydrology, and human disturbance), and Circuitscape to analyze habitat connectivity by applying circuit theory to identify potential wildlife movement corridors and optimal locations for mitigation measures like wildlife crossings.
