BACKGROUND: American Creole cattle presumably descend from animals imported from the Iberian Peninsula during the period of colonization and settlement, through different migration routes, and may have also suffered the influence of cattle directly imported from Africa. The introduction of European cattle, which began in the 18th century, and later of Zebu from India, has threatened the survival of Creole populations, some of which have nearly disappeared or were admixed with exotic breeds. Assessment of...

Understanding the evolutionary histories of invasive species is critical to adopt appropriate management strategies, but this process can be exceedingly complex to unravel. As illustrated in this study of the worldwide invasion of the woodwasp Sirex noctilio, population genetic analyses using coalescent-based scenario testing together with Bayesian clustering and historical records provide opportunities to address this problem. The pest spread from its native Eurasian range to the Southern Hemisphere in the 1900’s and recently to...

Data from: Mutualism effectiveness and vertical transmission of symbiotic fungal endophytes in response to host genetic background

Certain species of the Pooideae subfamily develop stress tolerance and herbivory resistance through symbiosis with vertically-transmitted, asexual fungi. This symbiosis is specific, and genetic factors modulate compatibility between partners. Although gene flow is clearly a fitness trait in allogamous grasses, since it injects hybrid vigor and raw material for evolution, it could reduce compatibility and thus, mutualism effectiveness. To explore the importance of host genetic background in modulating the performance of symbiosis, Lolium multiflorum plants,...
