Data from: Genetics of urban colonization: neutral and adaptive variation in coyotes (Canis latrans) inhabiting the New York metropolitan area

Alexandra L. DeCandia, Carol S. Henger, Amelia Krause, Linda J. Gormezano, Mark Weckel, Christopher Nagy, Jason Munshi-South & Bridgett M. VonHoldt
Theory predicts that range expansion results in genetic diversity loss in colonizing populations. Rapid reduction of population size exacerbates negative effects of genetic drift, while sustained isolation decreases neutral variation. Amid this demographic change, natural selection can act to maintain functional diversity. Thus, characterizing neutral and functional variation is critical for disentangling the evolutionary forces that shape genetic variation in newly established populations. Coyotes (Canis latrans) provide an ideal study system for examining the genetic...

Data from: Palaeoproteomics resolves sloth phylogeny

Samantha Presslee, Graham J. Slater, Francois Pujos, Analia M. Forasiepi, Roman Fischer, Kelly Molloy, Meaghan Mackie, Jesper V. Olsen, Alejandro Kramarz, Matias Taglioretti, Fernando Scaglia, Maximiliano Lezcano, José Luis Lanata, John Southon, Robert Feranec, Jonathan Bloch, Adam Hajduk, Fabiana M. Martin, Rodolfo Salas Gismondi, Marcelo Reguero, Christian De Muizon, Alex Greenwood, Brian T. Chait, Kirsty Penkman, Matthew Collins … & Ross D. E. MacPhee
The living tree sloths Choloepus and Bradypus are the only remaining members of Folivora, a major xenarthran radiation that occupied a wide range of habitats in many parts of the western hemisphere during the Cenozoic, including both continents and the West Indies. Ancient DNA evidence has played only a minor role in folivoran systematics, as most sloths lived in places not conducive to genomic preservation. Here we utilize collagen sequence information, both separately and in...

Data from: Enigmatic hook-like structures in Mesozoic ammonites (Scaphitidae)

Isabelle Kruta, Jeremie Bardin, Christopher Smith, Paul Tafforeau & Neil Landman
In the last few decades, hook-like structures have been reported in the Mesozoic ammonite family Scaphitidae. Despite their exceptional preservation and debates about their function, no detailed reconstruction of them has yet been made. For the first time, we describe the composition and detailed morphology of these structures in the body chambers of six specimens of the Campanian ammonite Rhaeboceras halli (Meek and Hayden) using high resolution X-ray imaging. The hook-like structures are composed of...

Data from: Quantifying the completeness of the bat fossil record

Emily E. Brown, Daniel D. Cashmore, Nancy B. Simmons & Richard J. Butler
Bats (Chiroptera) are one of the most successful extant mammalian orders, uniquely capable of powered flight and laryngeal echolocation. The timing and evidence for evolution of their novel adaptations has been difficult to ascertain from the fossil record due to chronological gaps (e.g. during the Palaeocene) and the fragmentary nature of most fossil bat material. Changes in fossil specimen completeness through time and space can bias our understanding of macroevolutionary processes. Here, we quantify the...

Data from: Population genetics of fruit bat reservoir informs the dynamics, distribution, and diversity of Nipah virus

Kevin J. Olival, Latinne Alice, Islam Ariful, Epstein H. Jonathan, Hersch Rebecca, Engstrand C. Rachel, Gurley S. Emily, George Amato, Luby P. Stephen & Daszak Peter
The structure and connectivity of wildlife host populations may influence zoonotic disease dynamics, evolution, and therefore spillover risk to people. Fruit bats in the genus Pteropus, or flying foxes, are the primary natural reservoir for henipaviruses - a group of emerging paramyxoviruses that threaten livestock and public health. In Bangladesh, Pteropus medius is the reservoir for Nipah virus - and viral spillover has led to human fatalities nearly every year since 2001. Here we use...

Data from: Diversification rates have no effect on the convergent evolution of foraging strategies in the most speciose genus of bats, Myotis

Ariadna E Morales, Manuel Ruedi, Kathryn Field & Bryan C Carstens
Adaptive radiations are defined as rapid diversification with phenotypic innovation led by colonization to new environments. Notably, adaptive radiations can occur in parallel when habitats with similar selective pressures are accessible promoting convergent adaptions. While convergent evolution appears to be a common process, it is unclear what are the main drivers leading the reappearance of morphologies or ecological roles. We explore this question in Myotis bats, the only Chiropteran genus with a worldwide distribution. Three...

Data from: Aerodynamic reconstruction of the primitive fossil bat Onychonycteris finneyi (Mammalia: Chiroptera)

Lucila I. Amador, Nancy B. Simmons & Norberto P. Giannini
Bats are the only mammals capable of powered flight. One of the oldest bats known from a complete skeleton is Onychonycteris finneyi from the Early Eocene (Green River Formation, Wyoming, 52.5 mya). Estimated to weigh ~40 g, Onychonycteris exhibits the most primitive combination of characters thus far known for bats. Here we reconstructed the aerofoil of the two known specimens, calculated basic aerodynamic variables, and compared them with those of extant bats and gliding mammals....

Data from: Tooth microwear and occlusal modes of euharamiyidans from the Jurassic Yanliao Biota reveal mosaic tooth evolution in Mesozoic allotherian mammals

Fangyuan Mao & Jin Meng
‘Haramiyidans’ are extinct mammaliaforms often clustered with Multituberculata as Allotheria, and with a fossil record extending from the Upper Triassic to possibly the Upper Cretaceous. For many decades, ‘haramiyidans’ were known only from isolated teeth, and their relationships to other mammaliaforms remain unclear. With the discovery of several euharamiyidans represented by skeletal specimens from the Jurassic Yanliao Biota, north‐western China, our knowledge of this group has significantly advanced. Nonetheless, much morphology, including dentition and occlusal...

Data from: A phylogenomic framework, evolutionary timeline and genomic resources for comparative studies of decapod crustaceans

Joanna M. Wolfe, Jesse W. Breinholt, Keith A. Crandall, Alan R. Lemmon, Emily Moriarty Lemmon, Laura E. Timm, Mark E. Siddall & Heather D. Bracken-Grissom
Comprising over 15 000 living species, decapods (crabs, shrimp and lobsters) are the most instantly recognizable crustaceans, representing a considerable global food source. Although decapod systematics have received much study, limitations of morphological and Sanger sequence data have yet to produce a consensus for higher-level relationships. Here, we introduce a new anchored hybrid enrichment kit for decapod phylogenetics designed from genomic and transcriptomic sequences that we used to capture new high-throughput sequence data from 94...

Data from: Phylogeography and species-limits in the red-shouldered hawk (Buteo lineatus): characterization of the northern Florida suture zone in birds

George F. Barrowclough, Jeff G. Groth, & Mary E. Blair
The North American red-shouldered hawk, Buteo lineatus, is comprised of two widely allopatric eastern and western populations with an additional well-marked subspecies in the Florida peninsula. The two eastern populations meet in northern Florida, the location of a well-known suture zone in many non-avian organisms. We sequenced the complete mitochondrial ND2 gene and two nuclear introns to investigate its genetic population structure and species status. No mitochondrial haplotypes were shared between the eastern and western...

Data from: Dietary adaptations and paleoecology of Lophialetidae (Mammalia: Tapiroidea) from the Eocene of the Erlian Basin, China: Combined evidence from mesowear and stable isotope analyses

Yanxin Gong, Yuanqing Wang, Yang Wang, Fang-Yuan Mao, Bin Bai, Haibing Wang, Qian Li, Xun Jin, Xu Wang & Jin Meng
Lophialetidae are an extinct group of endemic Asiatic tapiroids that are widely distributed in the Eocene sediments of Asia. Schlosseria magister and Lophialetes expeditus are the most abundant species in this family. However, their dietary and ecological characteristics are largely unknown to date. For the first time, we reconstruct the paleodiet and habitat of these two lophialetids using a combination of mesowear and stable carbon isotope analyses of fossil teeth excavated from the Erlian Basin,...

Data from: Dispersal out of Wallacea spurs diversification of Pteropus flying foxes, the world’s largest bats (Mammalia: Chiroptera)

Susan M. Tsang, Sigit Wiantoro, Maria Josefa Veluz, Norimasa Sugita, Y-Lan Nguyen, Nancy B. Simmons & David J. Lohman
Aim: Islands provide opportunities for isolation and speciation. Many landmasses in the Indo-Australian Archipelago (IAA) are oceanic islands, and founder-event speciation is expected to be the predominant form of speciation of volant taxa on these islands. We studied the biogeographic history of flying foxes, a group with many endemic species and a predilection for islands, to test this hypothesis and infer the biogeographic origin of the group. Location: Australasia, Indo-Australian Archipelago, Madagascar, Pacific Islands Taxon:...

Data from: Earth history and the passerine superradiation

Carl H. Oliveros, Daniel J. Field, Daniel T. Ksepka, F. Keith Barker, Alexandre Aleixo, Michael J. Andersen, Per Alström, Brett W. Benz, Edward L. Braun, Michael J. Braun, Gustavo A. Bravo, Robb T. Brumfield, R. Terry Chesser, Santiago Claramunt, Joel Cracraft, Andrés M. Cuervo, Elizabeth P. Derryberry, Travis C. Glenn, Michael G. Harvey, Peter A. Hosner, Leo Joseph, Rebecca T. Kimball, Andrew L. Mack, Colin M. Miskelly, A. Townsend Peterson … & Brant C. Faircloth
Avian diversification has been influenced by global climate change, plate tectonic movements, and mass extinction events. However, the impact of these factors on the diversification of the hyperdiverse perching birds (passerines) is unclear because family level relationships are unresolved and the timing of splitting events among lineages is uncertain. We analyzed DNA data from 4,060 nuclear loci and 137 passerine families using concatenation and coalescent approaches to infer a comprehensive phylogenetic hypothesis that clarifies relationships...

Data from: The chemical basis of a signal of individual identity: Shell pigment concentrations track the unique appearance of Common Murre eggs

Mark E Hauber, Alexander L Bond, Amy-Lee Kouwenberg, Gregory J Robertson, Erpur S Hansen, Mande Holford, Miri Dainson, Alec Luro & James Dale
In group-living species with parental care, the accurate recognition of one’s own young is critical to fitness. Because discriminating offspring within a large colonial group may be challenging, progeny of colonial breeders often display familial or individual identity signals to elicit and receive costly parental provisions from their own parents. For instance, the Common Murre (or Common Guillemot: Uria aalge) is a colonially breeding seabird that does not build a nest and lays and incubates...

Data from: Why is Amazonia a ‘source’ of biodiversity? climate-mediated dispersal and synchronous speciation across the Andes in an avian group (Tityrinae)

Lukas J. Musher, Mateus Ferreira, Anya L. Auerbach, Jessica McKay & Joel Cracraft
Amazonia is a ‘source’ of biodiversity for other Neotropical ecosystems, but which conditions trigger in situ speciation and emigration is contentious. Three hypotheses for how communities have assembled include (1) a stochastic model wherein chance dispersal events lead to gradual emigration and species accumulation, (2) diversity-dependence wherein successful dispersal events decline through time due to ecological limits, and (3) barrier displacement wherein environmental change facilitates dispersal to other biomes via transient habitat corridors. We sequenced...
