Simulating cryptic movements of a mangrove crab: Recovery phenomena after small scale fishery (original) (raw)

Field of neighbourhood Pattern-oriented modelling Competition Movement a b s t r a c t The semi-terrestrial burrowing crab Ucides cordatus is an important ecological component and economic resource of Brazilian mangrove forests. The crab population of the Caeté peninsula (the location of our study site) has been exploited for the last 40 years. Recovery of fished areas by crabs from non-fished areas under the roots of the mangrove tree Rhizophora mangle was hypothesized to be an important buffer mechanism against rapid overfishing.
