Data from: Phylogenomic analyses of more than 4000 nuclear loci resolve the origin of snakes among lizard families

Jeffrey W. Streicher & John J. Wiens
Squamate reptiles (lizards and snakes) are the most diverse group of terrestrial vertebrates, with more than 10 000 species. Despite considerable effort to resolve relationships among major squamates clades, some branches have remained difficult. Among the most vexing has been the placement of snakes among lizard families, with most studies yielding only weak support for the position of snakes. Furthermore, the placement of iguanian lizards has remained controversial. Here we used targeted sequence capture to...

Data from: Barcoding snakeheads (Teleostei, Channidae) revisited: discovering greater species diversity and resolving perpetuated taxonomic confusions

Cecilia Conte-Grand, Ralf Britz, Neelesh Dahanukar, Rajeev Raghavan, Rohan Pethiyagoda, Hoek Hui Tan, Renny Kurnia Hadiaty, Norsham S. Yaakob, Lukas Rüber & Heok Hui Tan
Snakehead fishes of the family Channidae are predatory freshwater teleosts from Africa and Asia comprising 38 valid species. Snakeheads are important food fishes (aquaculture, live food trade) and have been introduced widely with several species becoming highly invasive. A channid barcode library was recently assembled by Serrao and co-workers to better detect and identify potential and established invasive snakehead species outside their native range. Comparing our own recent phylogenetic results of this taxonomically confusing group...

Data from: Climatic niche evolution is faster in sympatric than allopatric lineages of the butterfly genus Pyrgus

Camille Pitteloud, Nils Arrigo, Tomasz Suchan, Alicia Mastretta-Yanes, Roger Vila, Vlad Dinca, Juan Hernández-Roldán, Ernst Brockmann, Yannick Chittaro, Irena Kleckova, Luca Fumagalli, Sven Buerki, Loïc Pellissier & Nadir Alvarez
Understanding how speciation relates to ecological divergence has long fascinated biologists. It is assumed that ecological divergence is essential to sympatric speciation, as a mechanism to avoid competition and eventually lead to reproductive isolation, while divergence in allopatry is not necessarily associated with niche differentiation. The impact of the spatial context of divergence on the evolutionary rates of abiotic dimensions of the ecological niche has rarely been explored for an entire clade. Here, we compare...

Data from: Persistence, impacts and environmental drivers of covert infections in invertebrate hosts

Inês Fontes, Hanna Hartikainen, Chris Williams & Beth Okamura
Background: Persistent covert infections of the myxozoan, Tetracapsuloides bryosalmonae, in primary invertebrate hosts (the freshwater bryozoan, Fredericella sultana) have been proposed to represent a reservoir for proliferative kidney disease in secondary fish hosts. However, we have limited understanding of how covert infections persist and vary in bryozoan populations over time and space and how they may impact these populations. In addition, previous studies have likely underestimated covert infection prevalence. To improve our understanding of the...

Data from: Time-calibrated molecular phylogeny of pteropods

Alice K. Burridge, Christine Hörnlein, Arie W. Janssen, Martin Hughes, Stephanie L. Bush, Ferdinand Marlétaz, Rebeca Gasca, Annelies C. Pierrot-Bults, Ellinor Michel, Jonathan A. Todd, Jeremy R. Young, Karen J. Osborn, Steph B.J. Menken, Katja T.C.A. Peijnenburg, Katja T. C. A. Peijnenburg & Steph B. J. Menken
Pteropods are a widespread group of holoplanktonic gastropod molluscs and are uniquely suitable for study of long-term evolutionary processes in the open ocean because they are the only living metazoan plankton with a good fossil record. Pteropods have been proposed as bioindicators to monitor the impacts of ocean acidification and in consequence have attracted considerable research interest, however, a robust evolutionary framework for the group is still lacking. Here we reconstruct their phylogenetic relationships and...

Data from: Phylogeny of Anophelinae using mitochondrial protein coding genes

Peter G. Foster, Tatiane M.P. De Oliveira, Eduardo S. Bergo, Jan E. Conn, Denise C. Sant'Ana, Sandra S. Nagaki, Silvio Nihei, Carlos E. Lamas, Christian González, Caio C. Moreira & Maria-Anice M. Sallum
Malaria is a vector-borne disease that is a great burden on the poorest and most marginalized communities of the tropical and subtropical world. About 41 species of Anopheline mosquitoes can effectively spread species of Plasmodium parasites that cause human malaria. Proposing a natural classification for the subfamily Anophelinae has been a continuous effort, addressed using both morphology and DNA sequence data. Monophyly of the genus Anopheles, and phylogenetic placement of the genus Bironella, subgenera Kerteszia,...

Data from: Metabarcoding of freshwater invertebrates to detect the effects of a pesticide spill

Carmelo Andujar, Paula Arribas, Clare Gray, Katherine Bruce, Guy Woodward, Douglas W. Yu & Alfried P. Vogler
Biomonitoring underpins the environmental assessment of freshwater ecosystems and guides management and conservation. Current methodology for surveys of (macro)invertebrates uses coarse taxonomic identification where species-level resolution is difficult to obtain. Next-generation sequencing of entire assemblages (metabarcoding) provides a new approach for species detection, but requires further validation. We used metabarcoding of invertebrate assemblages with two fragments of the cox1 "barcode" and partial nuclear ribosomal (SSU) genes, to assess the effects of a pesticide spill in...

Data from: Speciation below ground: tempo and mode of diversification in a radiation of endogean ground beetles

Carmelo Andújar, Sergio Pérez-González, Paula Arribas, Juan P. Zaballos, Alfried P. Vogler & Ignacio Ribera
Dispersal is a critical factor determining the spatial scale of speciation, which is constrained by the ecological characteristics and distribution of a species' habitat and the intrinsic traits of species. Endogean taxa are strongly affected by the unique qualities of the below-ground environment and its effect on dispersal, and contrasting reports indicate either high dispersal capabilities favoured by small body size and mediated by passive mechanisms, or low dispersal due to restricted movement and confinement...

Data from: The oldest erect cheilostome bryozoan: Jablonskipora gen. nov. from the upper Albian of south-west England

Silviu O. Martha & Paul D. Taylor
Although dominant at the present day, the bryozoan order Cheilostomata did not appear until the Late Jurassic. For over 55 million years after their first appearance, cheilostomes remained low in diversity and disparity, exclusively encrusting and scant in the fossil record. During the late Albian, however, cheilostomes began an explosive diversification coinciding with the appearance of several key novelties. In this paper, we describe a new monospecific cheilostome genus, Jablonskipora gen. nov. (type species Jablonskipora...

Data from: Molecular clocks indicate turnover and diversification of modern coleoid cephalopods during the Mesozoic Marine Revolution

Alastair R. Tanner, Dirk Fuchs, Inger E. Winkelmann, Thomas P. Gilbert, M. Sabrina Pankey, Angela M. Ribeiro, Kevin M. Kocot, Kenneth M. Halanych, Todd H. Oakley, Rute R. Da Fonseca, Davide Pisani, Jakob Vinther & M. Thomas P. Gilbert
Coleoid cephalopod molluscs comprise squid, cuttlefish and octopuses, and represent nearly the entire diversity of modern cephalopods. Sophisticated adaptations such as the use of colour for camouflage and communication, jet propulsion and the ink sac highlight the unique nature of the group. Despite these striking adaptations, there are clear parallels in ecology between coleoids and bony fishes. The coleoid fossil record is limited, however, hindering confident analysis of the tempo and pattern of their evolution....

Data from: Strong but taxon-specific responses of termites and wood-nesting ants to forest regeneration in Borneo

Annie Kimber & Paul Eggleton
Land use change is accelerating globally at the expense of biodiversity and ecosystem functioning. Invertebrates are numerically dominant and functionally important in old growth tropical rain forests but highly susceptible to the adverse effects of forest degradation and fragmentation. Ants (Formicidae) and termites (Blattodea: Termitoidae) perform crucial ecosystem services. Here, the potential effects of anthropogenic disturbance on ant and termite communities in dead wood are investigated. Community composition, generic richness, and occupancy rates of ants...

Data from: Global decline of bumblebees is phylogenetically structured and inversely related to species range size and pathogen incidence

Marina P. Arbetman, Gabriela Gleiser, Carolina L. Morales, Paul Williams & Marcelo A. Aizen
Conservation biology can profit greatly from incorporating a phylogenetic perspective into analyses of patterns and drivers of species extinction risk. We applied such an approach to analyse patterns of bumblebee (Bombus) decline. We assembled a database representing approximately 43% of the circa 260 globally known species, which included species extinction risk assessments following the International Union fo Conservation of Nature Red List categories and criteria, and information on species traits presumably associated with bumblebee decline....

Data from: Varyingly hungry caterpillars: predictive models and foliar chemistry suggest how to eat a rainforest

Simon T. Segar, Martin Volf, Brus Isua, Mentap Sisol, Conor M. Redmond, Margaret E. Rosati, Bradley Gewa, Kenneth Molem, Chris Dahl, Jeremy D. Holloway, Yves Basset, Scott E. Miller, George D. Weiblen, Juha-Pekka Salminen & Vojtech Novotny
A long-term goal in evolutionary ecology is to explain the incredible diversity of insect herbivores and patterns of plant host use in speciose groups like tropical Lepidoptera. Here we used standardised food-web data, multigene phylogenies of both trophic levels and plant chemistry data to model interactions between Lepidoptera larvae (caterpillars) from two lineages (Geometridae and Pyraloidea) and plants in species-rich lowland rainforest in New Guinea. Model parameters were used to make and test blind predictions...

Data from: Terrestrial reproduction as an adaptation to steep terrain in African toads

H. Christoph Liedtke, Hendrik Müller, Julian Hafner, Johannes Penner, David J. Gower, Tomáš Mazuch, Mark-Oliver Rödel & Simon P. Loader
How evolutionary novelties evolve is a major question in evolutionary biology. It is widely accepted that changes in environmental conditions shift the position of selective optima, and advancements in phylogenetic comparative approaches allow the rigorous testing of such correlated transitions. A longstanding question in vertebrate biology has been the evolution of terrestrial life histories in amphibians and here, by investigating African bufonids, we test whether terrestrial modes of reproduction have evolved as adaptations to particular...

Data from: The earliest bird-line archosaurs and the assembly of the dinosaur body plan

Sterling J. Nesbitt, Richard J. Butler, Martin D. Ezcurra, Paul M. Barrett, Michelle R. Stocker, Kenneth D. Angielczyk, Roger M. H. Smith, Christian A. Sidor, Grzegorz Niedźwiedzki, Andrey G. Sennikov & Alan J. Charig
The relationship between dinosaurs and other reptiles is well established, but the sequence of acquisition of dinosaurian features has been obscured by the scarcity of fossils with transitional morphologies. The closest extinct relatives of dinosaurs either have highly derived morphologies or are known from poorly preserved or incomplete material. Here we describe one of the stratigraphically lowest and phylogenetically earliest members of the avian stem lineage (Avemetatarsalia), Teleocrater rhadinus gen. et sp. nov., from the...

Data from: Shotgun mitogenomics across body size classes in a local assemblage of tropical Diptera: phylogeny, species diversity and mitochondrial abundance spectrum

Le Qin Choo, Alex Crampton-Platt & Alfried P. Vogler
Mitochondrial genomes can be assembled readily from shotgun-sequenced DNA mixtures of mass-trapped arthropods (“mitochondrial metagenomics”), speeding up the taxonomic characterization. Bulk sequencing was conducted on some 800 individuals of Diptera obtained by canopy fogging of a single tree in Borneo dominated by small (<1.5 mm) individuals. Specimens were split into five body size classes for DNA extraction, to equalize read numbers across specimens and to study how body size, a key ecological trait, interacts with...
