Data from: Multiple continental radiations and correlates of diversification in Lupinus (Leguminosae): testing for key innovation with incomplete taxon sampling

Christopher S. Drummond, Ruth J. Eastwood, Silvia T. S. Miotto & Colin E. Hughes
Replicate radiations provide powerful comparative systems to address questions about the interplay between opportunity and innovation in driving episodes of diversification and the factors limiting their subsequent progression. However, such systems have been rarely documented at intercontinental scales. Here, we evaluate the hypothesis of multiple radiations in the genus Lupinus (Leguminosae), which exhibits some of the highest known rates of net diversification in plants. Given that incomplete taxon sampling, background extinction, and lineage-specific variation in...

Data from: Inbreeding depression in pronghorn (Antilocapra americana) fawns

Stacey J. Dunn, Erin Clancey, Lisette P. Waits & John A. Byers
Although inbreeding depression affects survival, fitness and population viability, the extent of inbreeding depression in wild populations remains unclear. We examined inbreeding depression in the small, isolated National Bison Range (NBR), MT, pronghorn (Antilocapra americana) population following a bottleneck. We have studied the NBR pronghorn extensively since 1981, and we have detailed birth, survival and mate choice data. We genotyped all animals in the population between 1999-2010 at 19 microsatellite loci, assigned paternities to all...

Data from: Monitoring the effective population size of a brown bear (Ursus arctos) population using new single-sample approaches

Tomaž Skrbinšek, Maja Jelenčič, Lisette Waits, Ivan Kos, Klemen Jerina & Peter Trontelj
The effective population size (Ne) could be the ideal parameter for monitoring populations of conservation concern as it conveniently summarizes both the evolutionary potential of the population and its sensitivity to genetic stochasticity. However, tracing its change through time is difficult in natural populations. We applied four new methods for estimating Ne from a single sample of genotypes to trace temporal change in Ne for bears in the Northern Dinaric Mountains. We genotyped 510 bears...

Data from: Genetic versus census estimators of the opportunity for sexual selection in the wild

Stacey J. Dunn, Lisette P. Waits & John A. Byers
The existence of a direct link between intensity of sexual selection and mating system type is widely accepted. However, the quantification of sexual selection has proven problematical. Several measures of sexual selection have been proposed, including the operational sex ratio (OSR), breeding sex ratio (BSR) and opportunity for sexual selection (Imates). For a wild population of pronghorn (Antilocapra americana), we calculated OSR and BSR. We estimated Imates from census data on the spatial and temporal...
