- Sex, bugs and Haldane's rule: the nematode genus Pristionchus in the United States

We describe the Pristionchus – beetle association in the Eastern United States and show striking evolutionary and ecological patterns. Most Pristionchus isolates from American scarab beetles belong to five species, all of which differ from the European species. The two most closely related species, P. aerivorus and P. pseudaerivorus n. sp., follow Haldane's rule. The Colorado potato beetle is associated with the same species, P. uniformis in the United States and Europe, suggesting that P. uniformis was introduced to Europe together with its beetle vector. Together, the Pristionchus – beetle association provides a powerful tool for studying speciation, biodiversity, biogeography and species invasion on a global scale.
