Abstract


  • The idea of landscapes as shifting patch mosaics, structured by a range of biological and physical

    stochastic forces, is well suited to shallow tropical environments, where seagrass patches lie within a matrix of

    soft sediments or rocky substrates. The interaction of wave fields and tidal currents with carbonate sediment

    transport can result in linear morphologies of reef flat material with alternating sand tongues and seagrass beds.

    Patch-level metrics capture phenomena such as linearity in one variable, which can be evaluated over a gradient

    of predictable environmental change. Interrogating the statistical properties of patch ensembles enables the links

    between observed structures and the processes that govern them to be empirically investigated. This study

    demonstrates how habitat maps derived from remotely sensed Compact Airborne Spectrographic Imager

    (CASI) data can be used to investigate critical controls of landscape mosaics through the application of

    geostatistical techniques to Alphonse Atoll, Seychelles.
