Neutrality tests based on the distribution of haplotypes under an infinite-site model.
Non-African populations of Drosophila melanogaster have a unique origin.
This study confirms that the search for footprints of selection in the D. melanogaster genome must include a sufficient understanding of its history, and finds that all non-African populations show the same major haplotypes, though in various frequencies.
DNA barcode analysis: a comparison of phylogenetic and statistical classification methods
The study implies that taxonomists can influence the quality of their analyses either by choosing a method best-adapted to the configuration of their sample, or, given a certain method, increasing the sample size or altering the amount of molecular diversity.
Population structure among African and derived populations of Drosophila simulans: evidence for ancient subdivision and recent admixture.
It is shown that there is significant structure to D. simulans populations within Africa and directional selection, previously documented at G6pd, appears to have occurred within the coalescence time of the species, obscuring deep population history.
Power of Neutrality Tests to Detect Bottlenecks and Hitchhiking
It is shown that for moderate sequencing efforts, severe bottlenecks can be detected only after an intermediate time period has allowed for mutations to occur, preferably by frequency spectrum statistics.
MOLECULAR AND REPRODUCTIVE CHARACTERIZATION OF SIBLING SPECIES IN THE EUROPEAN EARWIG (FORFICULA AURICULARIA)

It is shown that the European earwig is comprised of two as yet unrecognized sibling species, and the molecular divergence between the two species, for a 627‐bp amplified fragment overlapping the COI and COII mitochondrial loci, is six times larger than intraspecific variation.
High genetic diversity of the symbiotic dinoflagellates in the coral Pocillopora meandrina from the South Pacific
The data suggests that hosts may acquire new symbionts after maternal transmission, possibly following a disturbance event, and that there was some host-symbiont fine-scale specificity detectable at the genetic resolution offered by microsatellites.
Discrimination of Culicoides obsoletus and Culicoides scoticus, potential bluetongue vectors, by morphometrical and mitochondrial cytochrome oxidase subunit I analysis.
Patterns of genetic variation do not correlate with geographical distance in the reef‐building coral Pocillopora meandrina in the South Pacific
Dispersal may be a critical factor in the ability of reef‐building corals to recover after major disturbances. We studied patterns of geographical structure using four microsatellite markers in seven…
Contrasted Polymorphism Patterns in a Large Sample of Populations From the Evolutionary Genetics Model Drosophila simulans
It is found that an eastern group of populations from continental Africa and Indian Ocean islands (Kenya, Tanzania, Madagascar, and Mayotte Island) is widespread, shows little differentiation, and has probably undergone demographic expansion.
