Many simulations of plant or animal dispersal across landscapes fragmented by human activity have represented the environment as habitat or non-habitat. Here, the consequences of representing habitat on grids as a continuous surface (0-1) versus as binary (0, 1) are examined for such models. Simulated landscapes with mean habitat quality of 0.5, with different variance, and with 50% each of habitat...
An individual-based, spatially explicit stochastic lattice model, CAPS, was designed to examine multiple processes responsible for spatial patterns of abundance and diversity of sessile species in heterogeneous landscapes. Species simulated by CAPS differ in habitat preferences (niche width), dispersal of propagules, and relative fecundity. The spatial distribution of habitat types are represented...
