This is an article about diversity and evolution of microbial eukaryotes published in PLoS ONE (2007). The goal of the study was to use estimates of current phylogenetic diversity in different habitats (warm, temperate, and cold) to infer (a) how long eukaryotes have been evolving in these regimes, and (b) whether such habitats likely persisted through extreme shifts in global temperatures (e.g. ice ages). The authors performed a census of microbial eukaryotic diversity in an arctic salt marsh using ribosomal DNA sequencing, then employed various well-accepted statistical and phylogenetic methods to compare their results to data from other studies. Testable hypotheses and expected results are clearly stated, and the unexpected conclusions of the study are thoroughly and logically argued. This paper would be a good candidate for discussion in an advanced undergraduate or graduate course.
