Metapopulation Nuclei Explorer

Interactive visualization of metapopulation dynamics and climate change impacts on species range shifts.

Features

• —Species Selection: Warm-adapted, Cool-adapted, or Generalist species
• —Multi-scale Analysis: 10km, 20km, or 100km hexagonal habitat patches
• —Climate Projections: Current vs future (2011-2040) equilibrium probabilities
• —Nuclei Identification: Climate change nuclei and at-risk populations

Methods

Based on the metapopulation framework of Talluto et al. (2017), this app visualizes:

• —Equilibrium occupancy probability (p*)
• —Colonization and extinction dynamics
• —Disequilibrium states (extinction debt, colonization credit)
• —Climate trajectory classification

Data

• —Climate data: CHELSA bioclimatic variables
• —Future projections: SSP1-2.6 (2011-2040)
• —Study area: California
