Data from: Masquerade is associated with polyphagy and larval overwintering in the Lepidoptera

Andrew D. Higginson, Leoni De Wert, Hannah M. Rowland, Michael P. Speed & Graeme D. Ruxton
Masquerading animals benefit from the difficulty that predators have in differentiating them from the inedible objects, such as twigs, that they resemble. The function of masquerade has been demonstrated, but how it interacts with the life history of organisms has not been studied. Here, we report the use of comparative analyses to test hypotheses linking masquerade to life-history parameters. We constructed a phylogenetic tree of the British species of the lepidoptera families Geometridae and Drepanidae...

Data from: Hierarchical polygyny in multiparous lesser flat-headed bats

Panyu Hua, Libiao Zhang, Guangjian Zhu, Gareth Jones, Shuyi Zhang & Stephen James Rossiter
How males gain access to mates and the potential for female choice will determine whether polygyny can operate at several levels, from within litters and groups to the wider population. Female lesser flat-headed bats (Tylonycteris pachypus) form maternity groups in bamboo stems. Unusually for bats, they are multiparous, providing the opportunity to test whether multi-level polygyny differs among males depending on whether they roost with females, with males, or are solitary. We genotyped 662 individuals...

Data from: Population divergence with or without admixture: selecting models using an ABC approach

Vitor C. Sousa, Mark A. Beaumont, Pedro Fernandes, Maria M. Coelho & Lounès Chikhi
Genetic data have been widely used to reconstruct the demographic history of populations, including the estimation of migration rates, divergence times and relative admixture contribution from different populations. Recently, increasing interest has been given to the ability of genetic data to distinguish alternative models. One of the issues that has plagued this kind of inference is that ancestral shared polymorphism is often difficult to separate from admixture or gene flow. Here, we applied an Approximate...

Data from: Evidence for evolutionary change associated with the recent range expansion of the British butterfly, Polyommatus agestis, in response to climate change

James Buckley, Roger K. Butlin & Jon R. Bridle
Poleward range expansions are a widespread response to recent climate change and are crucial for many species’ future persistence. However for many species evolutionary change in traits such as colonisation history and habitat preference may be necessary to track environmental change across a fragmented landscape. Understanding the likelihood and speed of such adaptive change has therefore become an important issue in determining the effect of ongoing climate change on extinction rates. We conducted an AFLP-based...

Data from: The evolution of cranial form and function in theropod dinosaurs: insights from geometric morphometrics

Stephen L. Brusatte, Manabu Sakamoto, Shaena Montanari & William E. H. Harcourt Smith
Theropod dinosaurs, an iconic clade of fossil species including Tyrannosaurus and Velociraptor, developed a great diversity of body size, skull form, and feeding habits over their 160+ million year evolutionary history. Here we utilise geometric morphometrics to study broad patterns in theropod skull shape variation, and compare the distribution of taxa in cranial morphospace (form) to both phylogeny and quantitative metrics of biting behaviour (function). We find that theropod skulls primarily differ in relative anteroposterior...

Data from: Best practices for justifying fossil calibrations

James F. Parham, Philip C. J. Donoghue, Christopher J. Bell, Tyler D. Calway, Jason J. Head, Patricia A. Holroyd, Jun G. Inoue, Randall B. Irmis, Walter G. Joyce, Daniel T. Ksepka, José S. L. Patané, Nathan D. Smith, James E. Tarver, Marcel Van Tuinen, Ziheng Yang, Kenneth D. Angielczyk, Jenny M. Greenwood, Christy A. Hipsley, Jacobs Louis, Peter J. Makovicky, Johannes Müller, Krister T. Smith, Jessica M. Theodor, Rachel C. M. Warnock, Michael J. Benton … & Louis Jacobs
Our ability to correlate biological evolution with climate change, geological evolution, and other historical patterns is essential to understanding the processes that shape biodiversity. Combining data from the fossil record with molecular phylogenetics represents an exciting synthetic approach to this challenge. The first molecular divergence dating analysis (Zuckerkandl and Pauling 1962) was based on a measure of the amino acid differences in the hemoglobin molecule; with replacement rates established (calibrated) using inaccurate paleontological age estimates...

Data from: The robustness and restoration of a network of ecological networks

Michael J. O. Pocock, Darren M. Evans & Jane Memmott
Understanding species’ interactions and the robustness of interaction networks to species loss is essential to understand the effects of species’ declines and extinctions. In most studies, different types of networks (such as food webs, parasitoid webs, seed dispersal networks, and pollination networks) have been studied separately. We sampled such multiple networks simultaneously in an agroecosystem. We show that the networks varied in their robustness; networks including pollinators appeared to be particularly fragile. We show that,...

Data from: The Rift Valley is a major barrier to dispersal of African clawed frogs (Xenopus) in Ethiopia

Ben J Evans, Shireen M Maarschalk, Simone A Mendel & Richard C Tinsley
The Ethiopian highlands – home to striking species diversity and endemism – are bisected by the Rift Valley, a zone of tectonic divergence. Using molecular data we examined the evolutionary history of two co-distributed species of African clawed frog (Xenopus clivii and X. largeni) that are endemic to this region. Our field collections substantially extend the known distribution of X. largeni, a species formerly known from highlands southeast of the Rift, but that also occurs...
