Data from: A refined modelling approach to assess the influence of sampling on palaeobiodiversity curves: new support for declining Cretaceous dinosaur richness

Graeme T. Lloyd
Modelling has been underdeveloped with respect to constructing palaeobiodiversity curves, but it offers an additional tool for removing sampling from their estimation. Here an alternative to subsampling approaches, which often require large sample sizes, is explored by the extension and refinement of a pre-existing modelling technique that uses a geological proxy for sampling. Application of the model to the three main clades of dinosaurs suggests that much of their diversity fluctuations cannot be explained by...

Data from: Reversal to air-driven sound production revealed by a molecular phylogeny of tongueless frogs, family Pipidae

Iker Irisarri, Miguel Vences, Diego San Mauro, Frank Glaw & Rafael Zardoya
BACKGROUND: Evolutionary novelties often appear by conferring completely new functions to pre- existing structures or by innovating the mechanism through which a particular function is performed. Sound production plays a central role in the behavior of frogs, which use their calls to delimit territories and attract mates. Therefore, frogs have evolved complex vocal structures capable of producing a wide variety of advertising sounds. It is generally acknowledged that most frogs call by moving an air...

Data from: Comparative phylogeography reveals a shared impact of Pleistocene environmental change in shaping genetic diversity within nine Anopheles mosquito species across the Indo-Burma biodiversity hotspot

Southeast Asia is one of the world’s richest regions in terms of biodiversity. An understanding of the distribution of diversity and the factors shaping it is lacking, yet essential for identifying conservation priorities for the region’s highly threatened biodiversity. Here we take a large scale comparative approach, combining data from nine forest associated Anopheles mosquito species and using statistical phylogeographic methods to disentangle the effects of environmental history, species specific ecology, and random coalescent effects....

Data from: Host tracking or cryptic adaptation? Phylogeography of Pediobius saulius (Hymenoptera, Eulophidae), a parasitoid of the highly invasive horse-chestnut leafminer

Classical biological control is often advocated as a tool for managing invasive species. However, accurate evaluations of parasitoid species complexes and assessment of host-specificity are impeded by the lack of morphological variation. Here we study the possibility of host races/species within the eulophid wasp Pediobius saulius, a pupal generalist parasitoid that parasitize the highly invasive horse-chestnut leaf-mining moth Cameraria ohridella. We analysed the population genetic structure, host associations and phylogeographic patterns of P. saulius in...

Data from: Hybridization and barriers to gene flow in an island bird radiation

Ben H. Warren, Eldredge Bermingham, Yann Bourgeois, Laura K. Estep, Robert P. Prys-Jones, Dominique Strasberg & Christophe Thébaud
While reinforcement may play a role in all major modes of speciation, relatively little is known about the timescale over which species hybridize without evolving complete reproductive isolation. Birds have high potential for hybridization, and islands provide simple settings for uncovering speciation and hybridization patterns. Here we develop a phylogenetic hypothesis for a phenotypically-diverse radiation of finch-like weaver-birds (Foudia) endemic to the western Indian Ocean islands. We find that unlike Darwin’s finches, each island-endemic Foudia...

Data from: Identifying heterogeneity in rates of morphological evolution: discrete character change in the evolution of lungfish (Sarcopterygii; Dipnoi)

Graeme T Lloyd, Steve C Wang & Stephen L Brusatte
Quantifying rates of morphological evolution is important in many macroevolutionary studies, and critical when assessing possible adaptive radiations and episodes of punctuated equilibrium in the fossil record. However, studies of morphological rates of change have lagged behind those on taxonomic diversification, and most authors have focused on continuous characters and quantifying patterns of morphological rates over time. Here, we provide a phylogenetic approach, using discrete characters and three statistical tests to determine points on a...

Data from: Taxonomic structure of the fossil record is shaped by sampling bias

Graeme T. Lloyd, Jeremy R. Young & Andrew B. Smith
Understanding biases that affect how species are partitioned into higher taxa is critical for much of palaeobiology, as higher taxa are commonly used to estimate species diversity through time. Using the deep-sea record of coccolithophorid microfossils over the last 150 million years (myr), we demonstrate that sampling and taxonomic effort are important drivers of the species/genus ratio. An unexpected two-stepped change in the ratio of species to genera over the last 150 myr correlates strongly...
