Data from: Genetic and ecological data reveal species boundaries between viviparous and oviparous lizard lineages

Luca Cornetti, G. Francesco Ficetola, Sean Hoban & Cristiano Vernesi
Identification of cryptic species is an essential aim for conservation biologists to avoid premature extinctions of ‘unrecognized’ species. Integrating different types of data can undoubtedly aid in resolving the issue of species delimitation. We studied here two lineages of the common lizard Zootoca vivipara that display different reproductive mode (the viviparous Z. v. vivipara and the oviparous Z. v. carniolica) and that overlap their distributional ranges in the European Alps. With the purpose of delimiting...

Data from: Heterogeneous rates of molecular evolution and diversification could explain the Triassic age estimate for angiosperms

Jeremy M. Beaulieu, Brian O'Meara, Peter Crane & Michael J. Donoghue
Dating analyses based on molecular data imply that crown angiosperms existed in the Triassic, long before their undisputed appearance in the fossil record in the Early Cretaceous. Following a re-analysis of the age of angiosperms using updated sequences and fossil calibrations, we use a series of simulations to explore the possibility that the older age estimates are a consequence of (i) major shifts in the rate of sequence evolution near the base of the angiosperms...

Data from: Identification of the notothenioid sister lineage illuminates the biogeographic history of an Antarctic adaptive radiation

Background: Antarctic notothenioids are an impressive adaptive radiation. While they share recent common ancestry with several species-depauperate lineages that exhibit a relictual distribution in areas peripheral to the Southern Ocean, an understanding of their evolutionary origins and biogeographic history is limited as the sister lineage of notothenioids remains unidentified. The phylogenetic placement of notothenioids among major lineages of perciform fishes, which include sculpins, rockfishes, sticklebacks, eelpouts, scorpionfishes, perches, groupers and soapfishes, remains unresolved. We investigate...
