nicheApport package simulate and fit the stochastic niche-oriented species abundance distribution models proposed by Tokeshi (1990, 1996). This package simulate species rank abundance distributions (RADs) and use Monte Carlo approach, proposed by Bersier & Sugihara (1997) and improved by Cassey & King (2001) and Mouillot et al. (2003), to fit models to replicated data.
The nicheApport package provides:
- Simulate species abundance models: Dominance Decay, Dominance Preemption, MacArthur Fraction, Random Fraction, Random Assortment and Power Fraction;
- Fit simulated rank abundance distribution to observed rank abundance data.
