Invasive phytophagous pests arising through a recent tropical evolutionary radiation: the Bactrocera dorsalis complex of fruit flies.
The Bactrocera dorsalis complex of tropical fruit flies contains 75 described species, largely endemic to Southeast Asia, and development of a phylogeny of the group is considered a high priority to provide a framework for future evolutionary and ecological studies.
Highways block gene flow and cause a rapid decline in genetic diversity of desert bighorn sheep
The results suggest that anthropogenic barriers constitute a severe threat to the persistence of naturally fragmented populations, and link a rapid reduction in genetic diversity to as few as 40 years of anthropogenic isolation.
Arthropods on islands: colonization, speciation, and conservation.
The literature on islands in the broadest sense is examined, whether surrounded by water or any other uninhabitable matrix) as it pertains to terrestrial arthropods, and the primary distinction between different island systems is "darwinian" islands (formed de novo) and "fragment" islands.
Towards writing the encyclopaedia of life: an introduction to DNA barcoding
Although still controversial, the scientific benefits of DNA barcoding include enabling species identification, including any life stage or fragment, facilitating species discoveries based on cluster analyses of gene sequences and providing insight into the diversity of life.
Population structure and colonization history of the olive fly, Bactrocera oleae (Diptera, Tephritidae)
Genetic similarity and assignment tests cluster the remaining populations into two genetic groups — Africa and a group including the Mediterranean basin and the American region, indicating that Africa, and not the Mediterranean, is the origin of flies infesting cultivated olive.
Geographic structure of insect populations: gene flow, phylogeography, and their uses.
The numerous case studies described herein illustrate the growing impact of geographic structure on insect science, as well as the importance of insect model systems for understanding general concepts in ecology and evolution.
