Genetics and the origin of a vector population: Aedes aegypti, a case study
TL;DR: A multivariate discriminant analysis revealed that the genetic differences among populations in six geographic regions and between two subspecies enable one to determine the regional origin of a population.
Population structure of a vector of human diseases: Aedes aegypti in its ancestral range, Africa.

TL;DR: A phylogenetic analysis combined with the genetic structure analyses suggest West Africa and especially Angola as the source of the New World's invasion, a scenario that fits well with the historic record of 16th‐century slave trade between Africa and Americas.
Acclimation of the European sea bass to freshwater: monitoring genetic changes by RAPD polymerase chain reaction to detect DNA polymorphisms
TL;DR: RAPD analysis is shown to be quite reproducible and sensitive enough to reveal high levels of variation among individuals from the same broodstock, and the use of multivariate analyses is suggested as a possible alternative to traditional population genetics techniques to analyze patterns of variation in the absence of a precise genetic interpretation.
Genetic Diversity of Brazilian Aedes aegypti: Patterns following an Eradication Program

TL;DR: The genetic patterns in present day populations of Ae.
Mitochondrial dna rates and biogeography in european newts (genus euproctus)
TL;DR: The data suggest that the cladogenic events leading to species formation in Euproctus and Triturus occurred very closely in time, indicating that the two genera may not be monophyletic.
