Incomplete knowledge of biodiversity remains a stumbling block for conservation planning, and even occurs within globally important Biodiversity Hotspots. Although technical advances have boosted the power of molecular biodiversity assessments, the link between DNA sequences and species and the analytics to discriminate entities, remain crucial. Here, we present an analysis of the first DNA barcode library for the freshwater fish fauna of the Mediterranean Biodiversity Hotspot (526 spp.), with virtually complete species coverage (498 spp.,...

Data from: An evaluation of fossil tip-dating versus node-age calibrations in tetraodontiform fishes (Teleostei: Percomorphaceae)

Dahiana Arcila, R. Alexander Pyron, James C. Tyler, Guillermo Ortí & Ricardo Betancur-R.
Time-calibrated phylogenies based on molecular data provide a framework for comparative studies. Calibration methods to combine fossil information with molecular phylogenies are, however, under active development, often generating disagreement about the best way to incorporate paleontological data into these analyses. This study provides an empirical comparison of the most widely used approach based on node-dating priors for relaxed clocks implemented in the programs BEAST and MrBayes, with two recently proposed improvements: one using a new...

Data from: Multilocus phylogeny and a new classification for Southeast Asian and Melanesian forest frogs (family Ceratobatrachidae)

Rafe M. Brown, Cameron D. Siler, Stephen J. Richards, Arvin C. Diesmos & David C. Cannatella
We present a near comprehensive, densely sampled, multilocus phylogenetic estimate of species relationships within the anuran family Ceratobatrachidae, a morphologically and ecologically diverse group of frogs from the island archipelagos of Southeast Asia and the South-West Pacific. Ceratobatrachid frogs consist of three clades: a small clade of enigmatic, primarily high-elevation, semi-aquatic Sundaland species currently assigned to Ingerana (for which we erect a new genus), which is the sister taxon of two large, monophyletic radiations, each...

Data from: Conservation genetics of the Philippine tarsier: cryptic genetic variation restructures conservation priorities for an island archipelago primate

Rafe M. Brown, Jennifer A. Weghorst, Karen V. Olson, Mariano R. M. Duya, Anthony J. Barley, Melizar V. Duya, Myron Shekelle, Irene Neri-Arboleda, Jacob A. Esselstyn, Nathaniel J. Dominy, Perry S. Ong, Gillian L. Moritz, Adrian Luczon, Mae Lowe L. Diesmos, Arvin C. Diesmos & Cameron D. Siler
Establishment of conservation priorities for primates is a particular concern in the island archipelagos of Southeast Asia, where rates of habitat destruction are among the highest in the world. Conservation programs require knowledge of taxonomic diversity to ensure success. The Philippine tarsier is a flagship species that promotes environmental awareness and a thriving ecotourism economy in the Philippines. However, assessment of its conservation status has been impeded by taxonomic uncertainty, a paucity of field studies,...

Data from: Population structure of the invasive forest pathogen Hymenoscyphus pseudoalbidus

Andrin Gross, Tsuyoshi Hosoya & Valentin Queloz
Understanding the genetic diversity and structure of invasive pathogens in source and introduced areas is crucial to reveal hidden biological aspects of an organism, to reconstruct the course of invasions and to establish effective control measures. Hymenoscyphus pseudoalbidus (anamorph: Chalara fraxinea) is an invasive and highly destructive fungal pathogen on common ash Fraxinus excelsior in Europe and occurs natively in east Asia. To get insights into the dispersal mechanism and the history of invasion, we...

Data from: Calibration uncertainty in molecular dating analyses: there is no substitute for the prior evaluation of time priors

Rachel C. M. Warnock, James F. Parham, Walter G. Joyce, Tyler R. Lyson & Philip C. J. Donoghue
Calibration is the rate-determining step in every molecular clock analysis and, hence, considerable effort has been expended in the development of approaches to distinguish good from bad calibrations. These can be categorized into a priori evaluation of the intrinsic fossil evidence, and a posteriori evaluation of congruence through cross-validation. We contrasted these competing approaches and explored the impact of different interpretations of the fossil evidence upon Bayesian divergence time estimation. The results demonstrate that a...

Data from: Niche divergence promotes rapid diversification of East African sky island white-eyes (Aves: Zosteropidae)

Siobhan C. Cox, Robert P. Prys-Jones, Jan C. Habel, Bernard A. Amakobe & Julia J. Day
The Eastern Afromontane biodiversity hotspot composed of highly fragmented forested highlands (sky islands) harbours exceptional diversity and endemicity, particularly within birds. To explain their elevated diversity within this region, models founded on niche conservatism have been offered, although detailed phylogeographic studies are limited to a few avian lineages. Here we focus on the recent songbird genus Zosterops, represented by montane and lowland members, to test the roles of niche conservatism versus niche divergence in the...
