“…Note that McCormick et al (1992) proved the asymptotic normality ofθ J in the balanced population case, but they require that the sample size and the number of species increase at the same rate.…”

SUMMARYFor two communities, species overlap has been defined by Smith et al. (1996) as the probability that a randomly selected species is present in both communities, given that it is present in at least one community. Species overlap can thus be used to describe the similarity of two communities. In contrast to the parametric estimator of Smith et al., we propose a Nonparametric Maximum Likelihood Estimator (NPMLE). We prove that the NPMLE is consistent and asymptotically normally distributed, and show that computation of the NPMLE and its standard error is straightforward. We also compare the NPMLE and the estimator of Smith et al. for a variety of situations.

The distribution of soil ciliates in three different habitats within a typical mangrove forest in Dongzhaigang, Hainan, China was investigated. The abundance, biodiversity, and community similarity of ciliates in fresh and air-dried soil with different, physical/chemical properties were analyzed. Three Classes, 11 Orders, 34 Genera, and 70 species of ciliates were found with the first dominant group being Hypotrichida. Ciliate biodiversities followed Site B < Site A < Site C in both fresh and dried samples. Ciliate abundance was positively correlated with soil moisture, salinity, organic matter (OM), total nitrogen (TN), total phosphorus (TP), and sulfate (SO 4 2− ), but negatively with pH and total potassium (TK). Site A and Site B and Site B and Site C showed the highest similarity in fresh and dried samples, respectively. The ubiquitous characteristics of ciliate distribution suggested their important role in food webs and nutrient cycling. The presence of Colpodida was linked with mangrove plants.
