Data from: Cryptic species, native populations and biological invasions by a eucalypt forest pathogenGuillermo Perez, Bernard Slippers, Michael J. Wingfield, Brenda D. Wingfield, Angus J. Carnegie & Treena I. Burgess
Human associated introduction of pathogens and consequent invasions are very evident in areas where no related organisms existed before. In areas where related but distinct populations or closely related cryptic species already exist, the invasion process is much harder to unravel. In this study, the population structure of the Eucalyptus leaf pathogen Teratosphaeria nubilosa was studied within its native range in Australia, including both commercial plantations and native forests. A collection of 521 isolates from...
Data from: Adiposity, compared with masculinity, serves as a more valid cue to immunocompetence in human mate choiceMarkus J. Rantala, Vinet Coetzee, Fhionna R. Moore, Ilona Skrinda, Sanita Kecko, Tatjana Krama, Inese Kivleniece & Indrikis Krams
According to the “good genes” hypothesis, females choose males based on traits that indicate the male’s genetic quality in terms of disease resistance. The “immunocompetence handicap hypothesis (ICHH)” proposed that secondary sexual traits serve as indicators of male genetic quality because they indicate that males can contend with the immunosuppressive effects of testosterone. Masculinity is commonly assumed to serve as such a secondary sexual trait. Yet women do not consistently prefer masculine looking men, nor...
Data from: High-throughput microsatellite marker development in two sparid species and verification of their transferability in the family SparidaeKerry Reid, Thierry B. Hoareau & Paulette Bloomer
Recently, 454 sequencing has emerged as a popular method for isolating microsatellites owing to cost-effectiveness and time saving. In this study, repeat-enriched libraries from two southern African endemic sparids (Pachymetopon blochii and Lithognathus lithognathus) were 454 GS-FLX sequenced. From these, 7370 sequences containing repeats (SCRs) were identified. A brief survey of 23 studies showed a significant difference between the number of SCRs when enrichment was performed first before 454 sequencing. We designed primers for 302...
Data from: Retracing the routes of introduction of invasive species: the case of the Sirex noctilio woodwasp.Emilie Boissin, Brett Hurley, Michael J. Wingfield, Rimvydas Vasaitis, Jan Stenlid, Chuck Davis, Peter De Groot, Rodrigo Ahumeda, Angus Carnegie, Arturo Goldarazena, Paula Klasmer, Beat Wermelinger & Bernard Slippers
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...
