Data from: Himalayan Cambrian brachiopods
Leonid E. Popov, Lars E. Holmer, Nigel C. Hughes, Mansoureh Ghabadi Pour, Paul M. Myrow & Mansoureh Ghobadi Pour
A synoptic analysis of previously published material and new finds reveals that Himalayan Cambrian brachiopods can be referred to 18 genera, of which 17 are considered herein. These contain 20 taxa assigned to species, of which five are new: Eohadrotreta haydeni, Aphelotreta khemangarensis, Hadrotreta timchristiorum, Prototreta? sumnaensis and Amictocracens? brocki. Well-preserved topotype material from the classic Parahio Valley section is described for three species that have not previously been illustrated photographically. A biostratigraphical scheme based...
Data from: Population-specific responses to an invasive species

Predicting the impacts of non-native species remains a challenge. As populations of a species are genetically and phenotypically variable, the impact of non-native species on local taxa could crucially depend on population-specific traits and adaptations of both native and non-native species. Bitterling fishes are brood parasites of unionid mussels and unionid mussels produce larvae that parasitize fishes. We used common garden experiments to measure three key elements in the bitterling–mussel association among two populations of...
Data from: Phylogeny of the island archipelago frog genus Sanguirana: another endemic Philippine radiation that diversified 'Out-of-Palawan'
Rafe M. Brown, Yong-Chao Su, Brenna Barger, Cameron D. Siler, Marites B. Sanguila, Arvin C. Diesmos & David C. Blackburn
Recent higher-level frog phylogenetic analyses have included a few members of the endemic Philippine frog genus Sanguirana. Although the monophyly of the group has never been disputed, the recent phylogenetically-supported inclusion of the Palawan Wood Frog (Sanguirana sanguinea) in this clade was highly unexpected. In addition, species boundaries and relationships remain unclear and new species continue to be discovered. We estimate the phylogeny for this endemic Philippine genus using two mitochondrial gene regions and six...
Data from: A lower jaw of Palaeoxonodon from the Middle Jurassic of the Isle of Skye, Scotland, sheds new light on the diversity of British stem therians
Roger A. Close, Brian M. Davis, Stig Walsh, Andrzej S. Wolniewicz, Matt Friedman & Roger B. J. Benson
The Middle Jurassic was a key interval of mammalian evolutionary history that witnessed the diversification of the therian stem-group. Great Britain has yielded a significant record of mammalian fossils from this interval, represented by numerous isolated jaws and teeth from the Bathonian of Oxfordshire and the Isle of Skye. This record captures a key period in early cladotherian evolution, with amphitheriids, peramurans and “stem zatherians” displaying intermediate talonid morphologies that document the evolutionary assembly of...
Data from: Limited role of character displacement in the coexistence of congeneric Anelosimus spiders in a Madagascan montane forest
Ingi Agnarsson, Nicholas J. Gotelli, Diego Agostini & Matjaž Kuntner
Evolutionary and ecological theory predicts that closely related and similar species should coexist infrequently because speciation is more likely to occur allopatrically than sympatrically, and because co-occurring species with similar traits may compete for limited resources, leading to competitive exclusion or character displacement. Here we study the unusual coexistence of 10 similar congeneric species of Anelosimus spiders within a small forest fragment in Madagascar. We asked if these species radiated in sympatry or allopatry, and...
Data from: A second New World hover fly, Toxomerus floralis (Fabricius) (Diptera: Syrphidae), recorded from the Old World, with description of larval pollen-feeding ecology
Kurt Jordaens, Georg Goergen, Ashley H. Kirk-Spriggs, Audrey Vokaer, Thierry Backeljau & Marc De Meyer
Recently (2013–2014), several hoverfly specimens from two localities in Benin and Cameroon (West and Central Africa) were caught from a species that we could not identify using existing identification keys for Afrotropical Syrphidae. Specific identification as Toxomerus floralis (Fabricius) was accomplished using morphology and various Neotropical identification keys. Corroboration of this identification was made by sequencing of the standard COI barcode region and a subsequent BLAST-IDS in BOLD that revealed a 100% sequence similarity with...
Data from: Ageing and reproduction: antioxidant supplementation alleviates telomere loss in wild birds
Elisa P. Badas, Javier Martínez, Juan Rivero De Aguilar Cachafeiro, Francisco Miranda, Jordi Figuerola & Santiago Merino
Reproduction is inherently costly. Environmental stressors, such as infection and limited food resources, can compromise investment at each breeding attempt. For example, recent data on captive birds showed that increased reproductive effort accelerates ageing. However, the effects of nutritional status and infection on ageing remain unknown. Telomeres function as protective caps at the ends of eukaryotic chromosomes, and changes in telomere length is a commonly used proxy for ageing. To partially address the mechanisms of...
Data from: Using phylogenomics to resolve mega-families: an example from Compositae
Jennifer R. Mandel, Rebecca B. Dikow & Vicki A. Funk
Next-generation sequencing and phylogenomics hold great promise for elucidating complex relationships among large plant families. Here we performed targeted capture of low copy sequences followed by next-generation sequencing on the Illumina platform in the large and diverse angiosperm family Compositae (Asteraceae). The family is monophyletic based on morphology and molecular data, yet many areas of the phylogeny have unresolved polytomies and interpreting phylogenetic patterns has been historically difficult. In order to outline a method and...
