East Africa Pollinator Connectivity Maps (Circuit-Theory Framework) # 🐝 Honeybee Functional Connectivity in East Africa ## 🌍 A Circuit-Theory-Based Framework for Pollinator Conservation This repository contains spatial datasets and derived geospatial products from the study: > Meltus, Q. J., et al. (2024). *A circuit-theory-based framework for modeling honeybee (*Apis mellifera*) functional connectivity to guide conservation corridors across East Africa using ecological drivers.* These datasets support a movement-based, ecological connectivity framework for pollinator conservation across Kenya, Uganda, and Tanzania. --- ## 🧭 Overview Maintaining pollinator connectivity in rapidly transforming landscapes is critical for ecosystem stability and food security. This work integrates species distribution modeling, remote sensing phenology, and landscape fragmentation into a circuit-theory-based resistance framework to identify functional honeybee corridors across East Africa. The outputs provide a spatially explicit foundation for: - Conservation corridor design - Restoration prioritization - Transboundary ecological planning - Pollinator-focused landscape management --- ## 📦 Repository Contents This repository contains the following key spatial datasets: ### 🧱 Composite Resistance Surface A unified landscape resistance layer integrating: - Honeybee habitat suitability (MaxEnt model) - Flowering Index (FI) - Floral fragmentation index (Frag) 📌 Interpretation: Represents **movement cost for honeybee dispersal across landscapes** --- ### 🌸 Flowering Index (FI) A phenology-derived metric of floral resource availability based on MODIS NDVI time series. (File was too big)- Reachout to meltusquinto@gmail.com for the raster Key characteristics: - Captures seasonal flowering pulses - Derived using harmonic regression of NDVI (2000–2025) - Includes wet and dry seasonal stratification - Combines peak vegetation productivity and amplitude variability 📌 Interpretation: Represents **spatiotemporal floral resource intensity** --- ### …
