Presentation Transcript

  1. Presence/absent of species in grid-cells across the landscape explained by: • a suite of environmental variables (23) • plus species attribute variables (5) • spatial effects

  2. Kogelberg-Hawequas sub-region Sample locations, with a 1x1 minute grid overlain (~41 x 107 km = 1554 grid cells) [versus ~37,000 cells for full CFR]

  3. The hierarchical structure of the model

  4. Full Model: Protea cynaroides 10 significant environmental covariates (Betas)

  5. Full Model: Sorocephalus imbricatus 0 significant environmental covariates (Betas)

  6. Data Thinning: Protea cynaroides

  7. Data Thinning: Aulax cancellata
