Data from: Marine invertebrate migrations trace climate change over 450 million years

Carl J Reddin, Ádám T Kocsis & Wolfgang Kiessling
Aim: Poleward migration is a clear response of marine organisms to current global warming but the generality and geographical uniformity of this response are unclear. Marine fossils are expected to record the range shift responses of taxa and ecosystems to past climate change. However, unequal sampling (natural and human) in time and space biases the fossil record, restricting previous studies of ancient migrations to individual taxa and events. We expect that temporal changes in the...

Data from: Synchronous diversification of Sulawesi's iconic artiodactyls driven by recent geological events

Thomas, Friederike Johansson, Abdul Haris Mustari, John Williams, Kusdiantoro Mohamad, Chandramaya Siska Damayanti … & Greger Larson
The high degree of endemism on Sulawesi has previously been suggested to have vicariant origins, dating back 40 Myr ago. Recent studies, however, suggest that much of Sulawesi’s fauna assembled over the last 15 Myr. Here, we test the hypothesis that more recent uplift of previously submerged portions of land on Sulawesi promoted diversification, and that much of its faunal assemblage is much younger than the island itself. To do so, we combined palaeogeographical reconstructions...

Data from: Matriline effects on metamorphic traits in a natural system in the European common frog (Rana temporaria)

Carolin Dittrich, Juliane Huster, Mark-Oliver Rödel & Heike Feldhaar
Successful reproduction is an important determinant of the fitness of an individual and of the dynamics of populations. Offspring of the European common frog (Rana temporaria) exhibit a high degree of variability in metamorphic traits. However, environmental factors alone cannot explain this phenotypic variability, and the influence of genetic factors remains to be determined. Here, we tested whether the maternal genotype influences developmental time, body size, and body condition of offspring in a forest pond...

Data from: Diversity change during the rise of tetrapods and the impact of the ‘Carboniferous rainforest collapse’

Emma M. Dunne, Roger A. Close, David J. Button, Neil Brocklehurst, Daniel D. Cashmore, Graeme T. Lloyd & Richard J. Butler
The Carboniferous and early Permian were critical intervals in the diversification of early four-limbed vertebrates (tetrapods), yet the major patterns of diversity and biogeography during this time remain unresolved. Previous estimates suggest that global tetrapod diversity rose continuously across this interval and that habitat fragmentation following the ‘Carboniferous rainforest collapse’ (CRC) drove increased endemism among communities. However, previous work failed to adequately account for spatial and temporal biases in sampling. Here, we reassess early tetrapod...

Data from: Using molecular phylogenies in island biogeography: it’s about time

Luis Valente, Albert B. Phillimore & Rampal S. Etienne
Island biogeography aims at inferring the processes that govern the assembly of communities in space and time. Molecular phylogenies can tell us about the timings of island colonisations and diversification, but have rarely been used for the estimation of colonisation, speciation and extinction rates on islands. In this study we illustrate the effects of including phylogenetic information with the Galápagos avifauna. We find that by including colonisation times we obtain much more precise and accurate...

Data from: Whole-body photoreceptor networks are independent of ‘lenses’ in brittle stars

Lauren Sumner-Rooney, Imran A. Rahman, Julia D. Sigwart & Esther Ullrich-Lüter
Photoreception and vision are fundamental aspects of animal sensory biology and ecology, but important gaps remain in our understanding of these processes in many species. The colour-changing brittle star Ophiocoma wendtii is iconic in vision research, speculatively possessing a unique whole-body visual system that incorporates information from nerve bundles underlying thousands of crystalline ‘microlenses’. The hypothesis that these form a sophisticated compound eye-like system regulated by chromatophore movement has been extensively reiterated, with consequent investigations...

Data from: Skeletal microstructure of Stenopterygius quadriscissus (Reptilia, Ichthyosauria) from the Posidonienschiefer (Posidonia Shale, Lower Jurassic) of Germany

Katherine L. Anderson, Patrick S. Druckenmiller, Gregory M. Erickson & Erin E. Maxwell
Ichthyosaurians (Ichthyosauria) are a major clade of secondarily aquatic marine tetrapods that occupied several major predatory niches during the Mesozoic Era. Multiple lines of evidence including isotopic, body shape and swimming modality analyses suggest they exhibited elevated growth and metabolic rates, and body temperatures. However, applications of osteohistological methods to test hypotheses regarding their physiology are few. Previous studies focused on the humeri, vertebrae and ribs from a small number of taxa. Here, we use...

Data from: Accounting for differences in species frequency distributions when calculating beta diversity in the fossil record

Neil Brocklehurst, Michael O. Day & Jörg Fröbisch
1. Beta diversity is a measure of the taxonomic differentiation between habitats/localities within an assemblage, and is normally calculated as a set of pairwise taxonomic “distances” between the localities. 2. Due to the incomplete sampling, beta diversity estimates for fossil assemblages will always be higher than the true value. However, the difference between the observed and true distances will vary greatly depending on differences in the shape of the relative abundance distribution. 3. Using simulations,...

Data from: Evolutionary adaptation to aquatic lifestyle in extinct sloths can lead to systemic alteration of bone structure

Eli Amson, Guillaume Billet & Christian De Muizon
Through phenotypic plasticity, bones can change in structure and morphology, in response to physiological and biomechanical influences over the course of individual life. Changes in bones also occur in evolution as functional adaptations to environment. In this study, we report on the evolution of bone mass increase (BMI) that occurred in the postcranium and skull of extinct aquatic sloths. Although non-pathological BMI in postcranial skeleton has been known in aquatic mammals, we here document general...

Data from: Demography and selection shape transcriptomic divergence in field crickets

Thomas Blankers, Sibelle Torres Vilaça, Isabelle Waurick, David A. Gray, R. Matthias Hennig, Camilla J. Mazzoni, Frieder Mayer & Emma L. Berdan
Gene flow, demography, and selection can result in similar patterns of genomic variation and disentangling their effects is key to understanding speciation. Here, we assess transcriptomic variation to unravel the evolutionary history of Gryllus rubens and G. texensis, cryptic field cricket species with highly divergent mating behavior. We infer their demographic history and screen their transcriptomes for footprints of selection in the context of the inferred demography. We find strong support for a long history...

Data from: Re-evaluation of the ontogeny and reproductive biology of the Triassic fish Saurichthys (Actinopterygii, Saurichthyidae)

Erin E. Maxwell, Thodoris Argyriou, Rudolf Stockar & Heinz Furrer
Viviparity has evolved independently at least 12 times in ray-finned fishes. However, the fossil record of actinopterygian viviparity is poor, with only two documented occurrences. Both of these are from the non-teleost actinopterygian Saurichthys, and include S. curionii and S. macrocephalus from the Middle Triassic Meride Limestone (Monte San Giorgio, Switzerland). Here, we present new data on the reproductive biology of these species, giving unprecedented insights into their life-history. Based on positional and preservational criteria,...
