Anuran limbs reflect microhabitat and distal, later-developing bones are more evolutionarily labile

Natasha Stepanova & Molly C. Womack
Tetrapod limbs have been used as a model system to investigate how selective pressures and constraints shape morphological evolution. Anurans have had many independent transitions to various microhabitats, allowing us to dissect how these factors influence limb morphology. Furthermore, anurans provide a unique system to test the generality of developmental constraints proposed in mammals, namely that later-developing limb bones are under less constraint and show more variation. We used micro-computed tomography scans of 236 species...

Data from: Comparing traditional and Bayesian approaches to ecological meta-analysis

Paula Pappalardo, Kiona Ogle, Elizabeth Hamman, James Bence, Bruce Hungate & Craig Osenberg
1. Despite the wide application of meta-analysis in ecology, some of the traditional methods used for meta-analysis may not perform well given the type of data characteristic of ecological meta-analyses. 2. We reviewed published meta-analyses on the ecological impacts of global climate change, evaluating the number of replicates used in the primary studies (ni) and the number of studies or records (k) that were aggregated to calculate a mean effect size. We used the results...

Data from: Visualizing mineralization processes and fossil anatomy using synchronous synchrotron X-ray fluorescence and X-ray diffraction mapping

Pierre Gueriau, Solenn Réguer, Nicolas Leclercq, Camila Cupello, Paulo M. Brito, Clément Jauvion, Séverin Morel, Sylvain Charbonnier, Dominique Thiaudière & Cristian Mocuta
Fossils, including those that occasionally preserve decay-prone soft-tissues, are mostly made of minerals. Accessing their chemical composition provides unique insight into their past biology and/or the mechanisms by which they preserve, leading to a series of developments in chemical and elemental imaging. However, the mineral composition of fossils, particularly where soft-tissues are preserved, is often only inferred indirectly from elemental data, while X-ray diffraction that specifically provides phase identification received little attention. Here, we show...

Biogeographic barriers, Pleistocene refugia, and climatic gradients in the southeastern Nearctic drive diversification in corn snakes (Pantherophis guttatus complex)

Edward Myers, Alexander McKelvy & Frank Burbrink
The southeastern Nearctic is a biodiversity hotspot that is also rich in cryptic species. This richness can be explained by numerous hypotheses affecting divergence, which include biogeographic barriers, adaptation to climatic gradients across this region, and Pleistocene speciation in glacial refugia. However, previous phylogeographic studies have both supported and refuted these hypotheses. Therefore, while one or more of these hypotheses may explain diversification, it is likely that taxa are forming within this region in species-specific...

Host identity and symbiotic association affects the genetic and taxonomic diversity of the clownfish-hosting sea anemone microbiome

Benjamin Titus, Robert Laroche, Estafania Rodriguez, Herman Wirshing & Christopher Meyer
All eukaryotic life engages in symbioses with a diverse community of bacteria that are essential for performing basic life functions. In many cases, eukaryotic organisms form additional symbioses with other macroscopic eukaryotes. The tightly-linked physical interactions that characterize many macroscopic symbioses creates opportunities for microbial transfer, which likely affects the diversity and function of individual microbiomes, and may ultimately lead to microbiome convergence between distantly related taxa. Here, we sequence the microbiomes of five species...

Beyond the landscape: resistance modelling infers physical and behavioural gene flow barriers to a mobile carnivore across a metropolitan area

Sophia Kimmig, Joscha Beninde, Myriam Brandt, Anna Schleimer, Stephanie Kramer-Schadt, Heribert Hofer, Konstantin Börner, Christoph Schulze, Ulrich Wittstatt, Mike Heddergott, Tania Halczok, Christoph Staubach & Alain Frantz
Urbanization affects key aspects of wildlife ecology. Dispersal in urban wildlife species may be impacted by geographical barriers but also by a species’ inherent behavioural variability. There are no functional connectivity analyses using continuous individual-based sampling across an urban-rural continuum that would allow a thorough assessment of the relative importance of physical and behavioural dispersal barriers. We used 16 microsatellite loci to genotype 374 red foxes (Vulpes vulpes) from the city of Berlin and surrounding...

Eye size and investment in frogs and toads correlate with adult habitat, activity pattern and breeding ecology

Kate N. Thomas, David J. Gower, Rayna C. Bell, Matthew K. Fujita, Ryan K. Schott & Jeffrey W. Streicher
Frogs and toads (Amphibia: Anura) display diverse ecologies and behaviours, which are often correlated with visual capacity in other vertebrates. Additionally, anurans exhibit a broad range of relative eye sizes, which have not previously been linked to ecological factors in this group. We measured relative investment in eye size and corneal size for 220 species of anurans representing all 55 currently recognized families and tested whether they were correlated with six natural history traits hypothesized...

Data from: A new small, mesorostrine inioid (Cetacea, Odontoceti, Delphinida) from four late Miocene localities of the Pisco Basin, Peru

Olivier Lambert, Alberto Collareta, Aldo Benites-Palomino, Claudio Di Celma, Christian De Muizon, Mario Urbina & Giovanni Bianucci
The moderately rich past diversity of the superfamily Inioidea (Cetacea, Odontoceti) in both the Atlantic and Pacific oceans contrasts with the present survival of a single genus (Inia, Amazon river dolphin, family Iniidae) in freshwater deposits of South America and of a single species (Pontoporia blainvillei, Franciscana, family Pontoporiidae) along the eastern coast of that continent. However, part of the late Miocene to Pliocene inioid fossil record is made of relatively fragmentarily known species, for...

Contribution of genetic versus plastic responses to adaptive patterns in a widespread butterfly along a latitudinal cline

Franziska Günter, Michaël Beaulieu, Kasimir F. Freiberg, Ines Welzel, Nia Toshkova, Žagar, Tatjana Simčič & Klaus Fischer
Understanding how organisms adapt to complex environments is a central goal of evolutionary biology and ecology. This issue is of special interest in the current era of rapidly changing climatic conditions. Here, we investigate clinal variation and plastic responses in life history, morphology, and physiology in the butterfly Pieris napi along a pan-European gradient by exposing butterflies raised in captivity to different temperatures. We found clinal variation in body size, growth rates and concomitant development...

Data from: One panel to rule them all: DArTcap genotyping for population structure, historical demography, and kinship analyses, and its application to a threatened shark

Pierre Feutry, Floriaan Devloo-Delva, Adrien Tran Lu Y, Stefano Mona, Rasanthi Gunasekera, Grant Johnson, Richard Pillans, Damian Jaccoud, Andrzej Kilian, David Morgan, Thor Saunders, Nicholas Bax & Peter Kyne
With recent advances in sequencing technology, genomic data are changing how important conservation management decisions are made. Applications such as Close-Kin Mark-Recapture demand large amounts of data to estimate population size and structure, and their full potential can only be realised through ongoing improvements in genotyping strategies. Here we introduce DArTcap, a cost-efficient method that combines DArTseq and sequence capture, and illustrate its use in a high resolution population analysis of Glyphis garricki, a rare,...

La Bioarchéologie en France : état des lieux, enjeux et perspectives

Rose-Marie Arbogast & Margareta Tengberg
La bioarchéologie est l’étude des vestiges biologiques recueillis dans le cadre de fouilles archéologiques tels que les restes végétaux et animaux, mais aussi leurs composants physico-chimiques, génétiques et les traces de substances organiques (lait, graisses, cires…). Elle regroupe un très large éventail d’approches et de disciplines : archéozoologie, archéobotanique, analyses chimiques, isotopiques ou moléculaires, menées à des échelles très diverses et envisagées de façon croisée. Son évolution récente est marquée par un important renouvellement tant...

Drosophila suzukii wing spot size is robust to developmental temperature

Ceferino Varón González, Antoine Fraimout & Vincent Debat
Phenotypic plasticity is an important mechanism allowing adaptation to new environments and as such it has been suggested to facilitate biological invasions. Under this assumption, invasive populations are predicted to exhibit stronger plastic responses than native populations. Drosophila suzukii is an invasive species whose males harbor a spot on the wing tip. In this study, by manipulating developmental temperature, we compare the phenotypic plasticity of wing spot size of two invasive populations with that of...

Data from: Phylogenomic data reveal reticulation and incongruence among mitochondrial candidate species in Dusky Salamanders (Desmognathus)

Robert Alexander Pyron, Kyle A. O'Connell, Emily Moriarty Lemmon, Alan R. Lemmon & David A. Beamer
Gene flow between evolutionarily distinct lineages is increasingly recognized as a common occurrence. Such processes distort our ability to diagnose and delimit species, as well as confound attempts to estimate phylogenetic relationships. A conspicuous example is Dusky Salamanders (Desmognathus), a common model-system for ecology, evolution, and behavior. Only 22 species are described; 7 in the last 40 years. However, mitochondrial datasets indicate the presence of up to 45 “candidate species” presenting a complex history of...

To hop or not to hop? the answer is in the bird trees

Pauline Provini & Elizabeth Höfling
Birds can use different types of gaits to move on the ground: they either walk, hop, or run. Although velocity can easily explain a preference for running, it remains unclear what drives a bird species to favour hopping over walking. As many hopping birds are relatively small and arboreal, we wanted to test the link between size, arboreality and hopping ability. First, we carried out ancestral character state reconstructions of size range, hopping ability and...

Modifications of the rainforest frugivore community are associated with reduced seed removal at the community level

Olivier Boissier
Tropical rainforests worldwide are under increasing pressure from human activities, which are altering key ecosystem processes such as plant-animal interactions. However, while the direct impact of anthropogenic disturbance on animal communities has been well studied, the consequences of such defaunation for mutualistic interactions such as seed dispersal remains chiefly understood at the plant species level. We asked whether communities of endozoochorous tree species had altered seed removal in forests affected by hunting and logging and...

To further focus on an endangered songbird and associated steppe birds. Location: Inner Mongolia, China Methods: We investigated the relative importance of abiotic and biotic factors driving the abundance and co-occurrence of steppe birds in Inner Mongolia by using joint species distribution models. We examined the general patterns of species assemblage, with...

Redescription of the cranial skeleton of the Early Devonian (Emsian) sarcopterygian Durialepis edentatus Otto, 2007 (Dipnomorpha; Porolepiformes)

Sam Giles, Jorge Mondéjar-Fernández & Matt Friedman
Porolepiforms represent a clade of Devonian stem lungfishes, divided into the cosmine-bearing and likely paraphyletic ‘Porolepidae’ (e.g., Porolepis, Heimenia) and the cosmine-free and stratigraphically younger Holoptychiidae (e.g., Holoptychius, Glyptolepis, Laccognathus). Data on the dermoskeleton are available for both groups, but are more limited for ‘porolepids’. Here we present new information on the ‘porolepid’ Durialepis edentatus from the Emsian (Early Devonian) of Germany based on micro-CT scanning. The material comprises an articulated skull of a single...

Data from: Protein-encoding ultraconserved elements provide a new phylogenomic perspective of Oestroidea flies (Diptera, Calyptratae)

Eliana Buenaventura, Michael W. Lloyd, Juan Manuel Perilla López, Vanessa L. González, Arianna Thomas-Cabianca & Torsten Dikow
The diverse superfamily Oestroidea with more than 15,000 known species includes among others, blow flies, flesh flies, bot flies, and the diverse tachinid flies. Oestroidea exhibit strikingly divergent morphological and ecological traits, but even with a variety of data sources and inferences there is no consensus on the relationships among major Oestroidea lineages. Phylogenomic inferences derived from targeted enrichment of ultraconserved elements or UCEs have emerged as a promising method for resolving difficult phylogenetic problems...

Extensive photobiont sharing in a rapidly-radiating cyanolichen clade

Manuela Dal Forno & Robert Lücking
Recent studies have uncovered remarkable diversity Dictyonema s.lat. basidiolichens, here recognized as subtribe Dictyonemateae. This group includes five genera and 148 species, but hundreds more await description. The photobionts of these lichens belong to Rhizonema, a recently resurrected cyanobacterial genus known by a single species. To further investigate photobiont diversity within Dictyonemateae, we generated 765 new cyanobacterial sequences from 635 specimens collected from 18 countries. The ITS barcoding locus supported the recognition of 200 mycobiont...

Positive selection and inactivation in vision and hearing genes of cetaceans

Michael McGowen, Georgia Tsagkogeorga, Joseph Williamson, Phillip Morin & Stephen Rossiter
The transition to an aquatic lifestyle in cetaceans (whales and dolphins) resulted in a radical transformation in their sensory systems. Toothed whales acquired specialized high-frequency hearing tied to the evolution of echolocation, while baleen whales evolved low-frequency hearing. More generally, all cetaceans show adaptations for hearing and seeing underwater. To determine the extent to which these phenotypic changes have been driven by molecular adaptation, we performed large-scale targeted sequence capture of 179 sensory genes across...

Mind the outgroup and bare branches in total-evidence dating: a case study of Pimpliform Darwin Wasps (Hymenoptera, Ichneumonidae)

Tamara Spasojevic, Ilari E. Sääksjärvi, Masato Ito, Stanislav Korenko, Seraina Klopfstein, Gavin R. Broad & Martin Schwarz
Taxon sampling is a central aspect of phylogenetic study design, but it has received limited attention in the context of total-evidence dating, a widely used dating approach that directly integrates molecular and morphological information from extant and fossil taxa. We here assess the impact of commonly employed outgroup sampling schemes and missing morphological data in extant taxa on age estimates in a total-evidence dating analysis under the uniform tree prior. Our study group is Pimpliformes,...

Underlying data for: Influence of temporally varying weatherability on CO2-climate coupling and ecosystem change in the late Paleozoic

Jon Richey, Isabel Montañez, Yves Goddéris, Cindy Looy, Neil Griffis & William DiMichele
This dataset contains the primary data used as input parameters in a mechanistic stomatal CO2 model (Franks et al., 2014 (Geophysical Research Letters)) and the Paleosol Barometer Uncertainty Quantifier (i.e., PBUQ; Breecker, 2013 (Geochemistry, Geophysics, Geosystems)), as well as age-adjusted CO2 data from Montañez et al., 2016 (Nature Geoscience). The stomatal parameters were measured by Richey et al., 2020 (Climate Of The Past) and the paleosol parameters are revised from Montañez et al., 2007 (Science)....

Phylogenomic analysis sheds light on the evolutionary pathways towards acoustic communication in Orthoptera

Hojun Song, Olivier Béthoux, Seunggwan Shin, Alexander Donath, Harald Letsch, Shanlin Liu, Duane D. McKenna, Guanliang Meng, Bernhard Misof, Lars Podsiadlowski, Xin Zhou, Benjamin Wipfler & Sabrina Simon
Acoustic communication is enabled by the evolution of specialised hearing and sound producing organs. In this study, we performed a large-scale macroevolutionary study to understand how both hearing and sound production evolved and affected diversification in the insect order Orthoptera, which includes many familiar singing insects, such as crickets, katydids, and grasshoppers. Using phylogenomic data, we firmly establish phylogenetic relationships among the major lineages and divergence time estimates within Orthoptera, as well as the lineage-specific...

Intraspecific variation and energy channel coupling within a Chilean kelp forest

Emma Elliott Smith, Chris Harrod, Felipe Docmac, Seth Newsome & Emma Elliott Smith
The widespread importance of variable types of primary production, or energy channels, to consumer communities has become increasingly apparent. However, the mechanisms underlying this ‘multichannel’ feeding remain poorly understood, especially for aquatic ecosystems that pose unique logistical constraints given the diversity of potential energy channels. Here, we use bulk tissue isotopic analysis along with carbon isotope (δ13C) analysis of individual amino acids to characterize the relative contribution of pelagic and benthic energy sources to a...

Le rapport d’analyse carpologique : exposé des minimums méthodologiques communs attendus par la communauté archéologique (carpologues, responsables d’opérations, services de l’État)

Bénédicte Pradat, Frédérique Durand, Françoise Toulemonde, Charlotte Hallavant, Aurélie Salavert, Julian Wiethold & Véronique Zech‐Matterne
La carpologie, initiée en France il y a 50 ans, s’est considérablement développée en grande partie grâce à l’augmentation des opérations d’archéologie préventive. La hausse sensible du nombre de carpologues, l’accroissement des études qui en résulte et la multiplication des cadres institutionnels, publics ou privés, dans lesquels les études carpologiques sont réalisées, ont rendu nécessaire une réflexion collective sur les minimums méthodologiques devant apparaître dans les rapports d’études carpologiques. En effet, la mise en œuvre...
