演講題目：A Statistical Approach to Estimate Soil Ciliate Diversity and Distribution based on Data from Five Continents摘要：A total of 359 soil samples (quadrats) collected from five continents (Africa, Asia, Australia, Europe and South America) were investigated for the presence/absence of soil ciliate species. Merging records by species identity, we have compiled a master data list (species by sample matrix). Based on the data, the statistical ACE (abundance-based coverage estimation) model which links observed data to unseen species is applied to assess regional and global soil ciliate species richness. Besides, after taking some modifications, the adjusted abundance-based Jaccard (or Sorensen) index can also be applied to estimate the similarity between any two continents in the quadrat sampling data. The models, estimates, and the results are described in the talk.
