Formatted abstract
The hypothesis that species richness in tropical, tidal (mangrove) forests in the eastern and western portions of the Australian continent is influenced by different suites of environmental parameters is investigated. Data for species presence/absence and quantitative measures of nine environmental variables from ninety-two estuaries around the tropical coast of Australia were used to test the hypothesis. Linear models were developed and compared for each region. For eastern Australia ⩾ 53% of the variance in species richness was explained compared to ⩾ 70.0% of the variance for western Australian mangrove forests. Maximum and minimum temperatures were positively correlated with species richness in both regions. Increasing temperatures led to increases in species richness. Tidal amplitude is inversely related to species richness in the east and west. Estuaries with larger tidal amplitudes have fewer species than estuaries with smaller tidal ranges. Estuary length, the size of the surrounding catchment, rainfall variation and the frequency of tropical cyclones have significant effects on species richness in eastern but not western mangrove forests. Estuaries which are long and have large catchments tend to have more species than those being shorter with smaller catchments. High interannual rainfall variability and frequent cyclones tend to decrease species richness in the east. The amount of freshwater runoff is inversely related to species richness in the western mangrove forests but not in eastern forests. Although similarities do exist, there are important differences between eastern and western mangrove forests in the response of species richness to the environment.
