Data from: Assessment of available anatomical characters for linking living mammals to fossil taxa in phylogenetic analyses

Thomas Guillerme & Natalie Cooper
Analyses of living and fossil taxa are crucial for understanding biodiversity through time. The total evidence method allows living and fossil taxa to be combined in phylogenies, using molecular data for living taxa and morphological data for living and fossil taxa. With this method, substantial overlap of coded anatomical characters among living and fossil taxa is vital for accurately inferring topology. However, although molecular data for living species are widely available, scientists generating morphological data...

Data from: Repeated eye reduction events reveal multiple pathways to degeneration in a family of marine snails

Lauren Sumner-Rooney, Julia D. Sigwart, Jenny McAfee, Lisa Smith & Suzanne T. Williams
Eye reduction occurs in many troglobitic, fossorial, and deep-sea animals but there is no clear consensus on its evolutionary mechanism. Given the highly conserved and pleiotropic nature of many genes instrumental to eye development, degeneration might be expected to follow consistent evolutionary trajectories in closely related animals. We tested this in a comparative study of ocular anatomy in solariellid snails from deep and shallow marine habitats using morphological, histological, and tomographic techniques, contextualized phylogenetically. Of...

Data from: X-rays and virtual taphonomy resolve the first Cissus (Vitaceae) macrofossils from Africa as early diverging members of the genus

Neil F. Adams, Margaret E. Collinson, Selena Y. Smith, Marion K. Bamford, Félix Forest, Panagiota Malakasi, Federica Marone & Dan Sykes
PREMISE OF THE STUDY: Fossilized seeds similar to Cissus (Vitaceae) have been recognized from the Miocene of Kenya, though some were previously assigned to the Menispermaceae. We undertook a comparative survey of extant African Cissus seeds to identify the fossils and consider their implications for the evolution and biogeography of Cissus and for African early Miocene paleoenvironments. METHODS: Micro-computed tomography (µCT) and synchrotron-based X-ray tomographic microscopy (SRXTM) were used to study seed morphology and anatomy....

Data from: Exploring the universal ecological responses to climate change in a univoltine butterfly

Phillip B. Fenberg, Angela Self, John R. Stewart, Rebecca J. Wilson & Stephen J. Brooks
1. Animals with distinct life stages are often exposed to different temperatures during each stage. Thus, how temperature affects these life stages should be considered for broadly understanding the ecological consequences of climate warming on such species. For example, temperature variation during particular life stages may affect respective change in body size, phenology and geographic range, which have been identified as the “universal” ecological responses to climate change. While each of these responses has been...

Data from: Interspecific interactions through 2 million years: are competitive outcomes predictable?

Lee Hsiang Liow, Emanuela Di Martino, Kjetil Lysne Voje, Seabourne Rust & Paul D. Taylor
Ecological interactions affect the survival and reproduction of individuals. However, ecological interactions are notoriously difficult to measure in extinct populations, hindering our understanding of how the outcomes of interactions such as competition vary in time and influence long-term evolutionary changes. Here, the outcomes of spatial competition in a temporally continuous community over evolutionary timescales are presented for the first time. Our research domain is encrusting cheilostome bryozoans from the Wanganui Basin of New Zealand over...

Data from: Metabarcoding and mitochondrial metagenomics of endogean arthropods to unveil the mesofauna of the soil

Paula Arribas, Carmelo Andújar, Kevin Hopkins, Matthew Shepherd & Alfried P. Vogler
Biological communities inhabiting the soil are among the most diversified, complex and yet most poorly studied terrestrial ecosystems. The greatest knowledge gaps apply to the arthropod mesofauna (0·1–2 mm body size) because conventional morphological and molecular approaches are in many cases insufficient for the characterisation of these complex communities. The development of high-throughput sequencing (HTS) methodologies is required to solve current impediments and to further advance our understanding of below-ground biodiversity. We propose a flotation–Berlese–flotation...

Data from: Lessons from genome skimming of arthropod-preserving ethanol

Benjamin Linard, Paula Arribas, Carmelo Andújar, Alex Crampton-Platt & Alfried P. Vogler
Field-collected specimens of invertebrates are regularly killed and preserved in ethanol, prior to DNA extraction from the specimens, while the ethanol fraction is usually discarded. However, DNA may be released from the specimens into the ethanol, which can potentially be exploited to study species diversity in the sample without the need for DNA extraction from tissue. We used shallow shotgun sequencing of the total DNA to characterize the preservative ethanol from two pools of insects...

Data from: Beyond neutral and forbidden links: morphological matches and the assembly of mutualistic hawkmoth-plant networks

Federico D. Sazatornil, Marcela Moré, Santiago Benitez-Vieyra, Andrea A. Cocucci, Ian J. Kitching, Boris O. Schlumpberger, Paulo E. Oliveira, Marlies Sazima & Felipe W. Amorim
A major challenge in evolutionary ecology is to understand how co-evolutionary processes shape patterns of interactions between species at community level. Pollination of flowers with long corolla tubes by long-tongued hawkmoths has been invoked as a showcase model of co-evolution. Recently, optimal foraging models have predicted that there might be a close association between mouthparts' length and the corolla depth of the visited flowers, thus favouring trait convergence and specialization at community level. Here, we...

Data from: Phylogeny and new taxonomy of the Booted Eagles (Accipitriformes: Aquilinae)

Heather R. L. Lerner, Les Christidis, Anita Gamauf, Carole Griffiths, Elisabeth Haring, Christopher J. Huddleston, Sonia Kabra, Annett Kocum, Meade Krosby, Kirsti Kvaloy, David Mindell, Pamela Rasmussen, Nils Rov, Rachel Wadleigh, Michael Wink & Jan Ove Gjershaug
We present a phylogeny of all booted eagles (38 extant and one extinct species) based on analysis of published sequences from seven loci. We find molecular support for five major clades within the booted eagles: Nisaetus (10 species), Spizaetus (4 species), Clanga (3 species), Hieraaetus (6 species) and Aquila (11 species), requiring generic changes for 14 taxa. Additionally, we recommend that the Long-crested Eagle (Lophaetus occipitalis) and the Black Eagle (Ictinaetus malaiensis) remain in their...

Data from: Australian spiny mountain crayfish and their temnocephalan ectosymbionts: an ancient association on the edge of coextinction?

Jennifer F. Hoyal Cuthill, Kim B. Sewell, Lester R. G. Cannon, Michael A. Charleston, Susan Lawler, D. Timothy J. Littlewood, Peter D. Olson & David Blair
Australian spiny mountain crayfish (Euastacus, Parastacidae) and their ecotosymbiotic temnocephalan flatworms (Temnocephalida, Platyhelminthes) may have co-occurred and interacted through deep time, during a period of major environmental change. Therefore, reconstructing the history of their association is of evolutionary, ecological, and conservation significance. Here, time-calibrated Bayesian phylogenies of Euastacus species and their temnocephalans (Temnohaswellia and Temnosewellia) indicate near-synchronous diversifications from the Cretaceous. Statistically significant cophylogeny correlations between associated clades suggest linked evolutionary histories. However, there is...

Data from: The ‘dance’ of life: visualizing metamorphosis during pupation in the blow fly Calliphora vicina by X-ray video imaging and micro-computed tomography

Martin J. R. Hall, Thomas J. Simonsen & Daniel Martín-Vega
The dramatic metamorphosis from larva to adult of insect orders such as Diptera cannot usually be witnessed because it occurs within an opaque structure. For the cyclorrhaphous dipterans, such as blow flies, this structure is the puparium, formed from the larval cuticle. Here, we reveal metamorphosis within the puparium of a blow fly at higher temporal resolution than previously possible with two-dimensional time-lapse videos created using the X-ray within a micro-computed tomography scanner, imaging development...

Data from: Exploring phylogenetic relationships within Myriapoda and the effects of matrix composition and occupancy on phylogenomic reconstruction

Rosa Fernández, Gregory D. Edgecombe & Gonzalo Giribet
Myriapods, including the diverse and familiar centipedes and millipedes, are one of the dominant terrestrial arthropod groups. Although molecular evidence has shown that Myriapoda is monophyletic, its internal phylogeny remains contentious and understudied, especially when compared to those of Chelicerata and Hexapoda. Until now, efforts have focused on taxon sampling (e.g., by including a handful of genes from many species) or on maximizing matrix size (e.g., by including hundreds or thousands of genes in just...
