On defining and finding islands of trees and mitigating large island bias

Ana Serra Silva & Mark Wilkinson
How best can we summarise sets of phylogenetic trees? Systematists have relied heavily on consensus methods, but if tree distributions can be partitioned into distinct subsets it may be helpful to provide separate summaries of these rather than relying entirely upon a single consensus tree. How sets of trees can most helpfully be partitioned and represented leads to many open questions, but one natural partitioning is provided by the islands of trees found during tree...

Eggs of extinct dwarf island emus retained large-size: Electronic supplementary material

Julian Hume & Christian Robertson
Islands off southern Australia once harboured three subspecies of the mainland emu (Dromaius novaehollandiae), the smaller Tasmanian emu (D. n. diemenensis), and two dwarf emus, King Island emu (D. n. minor) and Kangaroo Island emu (D. n. baudinianus), which all became extinct rapidly after discovery by human settlers. Little was recorded about their life histories and only a few historical museum specimens exist, including a number of complete eggs from Tasmania and a unique egg...

A broadly resolved molecular phylogeny of New Zealand cheilostome bryozoans as a framework for hypotheses of morphological evolution

Russell Orr, E. Di Martino, D.P. Gordon, M.H. Ramsfjell, H.L. Mello, A.M. Smith & L.H. Liow
Larger and larger molecular phylogenies based on ever more genes are becoming commonplace with the advent of cheaper and more streamlined sequencing and bioinformatics pipelines. However, many groups of inconspicuous but no less evolutionarily or ecologically important marine invertebrates are still neglected in the quest for understanding species- and higher-level phylogenetic relationships using high-throughput sequencing approaches. Here, we alleviate this issue by presenting a 17 gene phylogeny of >200 newly sequenced cheilostome bryozoan species, mainly...

Community metabarcoding reveals the relative role of environmental filtering and spatial processes in metacommunity dynamics of soil microarthropods across a mosaic of montane forests

Víctor Noguerales, Emmanouil Meramveliotakis, Adrián Castro-Insua, Carmelo Andújar, Paula Arribas, Thomas Creedy, Isaac Overcast, Hélène Morlon, Brent C. Emerson, Alfried P. Vogler & Anna Papadopoulou
Disentangling the relative role of environmental filtering and spatial processes in driving metacommunity structure across mountainous regions remains challenging, as the way we quantify spatial connectivity in topographically and environmentally heterogeneous landscapes can influence our perception of which process predominates. More empirical datasets are required to account for taxon- and context-dependency but relevant research in understudied areas is often compromised by the taxonomic impediment. We here employed haplotype-level community DNA metabarcoding, enabled by stringent filtering...

What you sample is what you get: ecomorphological variation in Trithemis (Odonata, Libellulidae) dragonfly wings reconsidered

Norman MacLeod, Banjamin Price & Zachary Stevens
Abstract Background The phylogenetic ecology of the Afro-Asian dragonfly genus Trithemis has been investigated previously by Damm et al. (in Mol Phylogenet Evol 54:870–882, 2010) and wing ecomorphology by Outomuro et al. (in J Evol Biol 26:1866–1874, 2013). However, the latter investigation employed a somewhat coarse sampling of forewing and hindwing outlines and reported results that were at odds in some ways with expectations given the mapping of landscape and water-body preference over the Trithemis...

Spatial patterns of phylogenetic diversity and endemism in the Western Ghats, India: a case study using ancient predatory arthropods

D. K. Bharti, Greg Edgecombe, Praveen Karanth & Jahnavi Joshi
The Western Ghats (WG) mountain chain in peninsular India is a global biodiversity hotspot, one in which patterns of phylogenetic diversity and endemism remain to be documented across taxa. We used a well-characterized community of ancient soil predatory arthropods from the WG to understand diversity gradients, identify hotspots of endemism and conservation importance, and highlight poorly-studied areas with unique biodiversity. We compiled an occurrence dataset for 19 species of scolopendrid centipedes, which was used to...

Evolution of body size and wing shape trade-offs in arsenurine silkmoths

Chris Hamilton, Nathalie Winiger, Juliette Rubin, Jesse Breinholt, Rodolphe Rougerie, Ian Kitching, Jesse Barber & Akito Kawahara
One of the key objectives in biological research is understanding how evolutionary processes have produced Earth's diversity. A critical step towards revealing these processes is an investigation of evolutionary tradeoffs – that is, the opposing pressures of multiple selective forces. For millennia, nocturnal moths have had to balance successful flight, as they search for mates or host plants, with evading bat predators. However, the potential for evolutionary trade-offs between wing shape and body size are...

Functional constraints during development limit jaw shape evolution in marsupials

Anne-Claire Fabre, Carys Dawling, Roberto Portela Miguez, Vincent Fernandez, Eve Noirault & Anjali Goswami
Differences in jaw function experienced through ontogeny can have striking consequences for evolutionary outcomes, as has been suggested for the major clades of mammals. In contrast to placentals, marsupial newborns have an accelerated development of the head and forelimbs, allowing them to crawl to the mother’s teats to suckle within just a few weeks of conception. The different functional requirements that marsupial newborns experience in early postnatal development have been hypothesized to have constrained their...

Evolutionary modularity, integration and disparity in an accretionary skeleton: Analysis of venerid Bivalvia

Stewart Edie, Safia Khouja, Katie Collins, Nicholas Crouch & David Jablonski
Modular evolution, the relatively independent evolution of body parts, may promote high morphological disparity in a clade. Conversely, integrated evolution via the stronger covariation of parts may limit disparity. However, integration can also promote high disparity by channeling morphological evolution along lines of least resistance—a process that may be particularly important in the accumulation of disparity among organisms with accretionary growth, as in many invertebrate systems. We use a time-calibrated phylogenetic hypothesis and high-density, 3D...

Data from: Reliable wolf-dog hybrid detection in Europe using a reduced SNP panel developed for non-invasively collected samples

Jenni Harmoinen, Alina Von Thaden, Jouni Aspi, Laura Kvist, Berardino Cocchiararo, Anne Jarausch, Andrea Gazzola, Teodora Sin, Hannes Lohi, Marjo Hytönen, Ilpo Kojola, Astrid Vik Stronen, Romolo Caniglia, Federica Mattucci, Marco Galaverni, Raquel Godinho, Aritz Ruiz-González, Ettore Randi, Violeta Muñoz-Fuentes & Carsten Nowak
Background: Understanding the processes that lead to hybridization of wolves and dogs is of scientific and management importance, particularly over large geographical scales, as wolves can disperse great distances. However, a method to efficiently detect hybrids in routine wolf monitoring is lacking. Microsatellites offer only limited resolution due to the low number of markers showing distinctive allele frequencies between wolves and dogs. Moreover, calibration across laboratories is time-consuming and costly. In this study, we selected...

Supplemental Material for \"Biomechanical analyses of Cambrian euarthropod limbs reveal their effectiveness in mastication and durophagy\"

Russell Bicknell, James Holmes, Gregory Edgecombe, Sarah Losso, Javier Ortega-Hernández, Stephen Wroe & John Paterson
Durophagy arose in the Cambrian and greatly influenced the diversification of biomineralised defensive structures throughout the Phanerozoic. Spinose gnathobases on protopodites of Cambrian euarthropod limbs are considered key innovations for shell-crushing, yet few studies have demonstrated their effectiveness with biomechanical models. Here we present finite element analysis models of two Cambrian trilobites with prominent gnathobases—Redlichia rex and Olenoides serratus—and compare these to the protopodites of the Cambrian euarthropod Sidneyia inexpectans and the modern American horseshoe...

An integrated phylogenetic reassessment of the parasitoid superfamily Platygastroidea (Hymenoptera: Proctotrupomorpha) results in a revised familial classification

Chen Huayan, Lahey Zachary, Elijah J. Talamas, Alejandro A. Valerio, Ovidiu A. Popovici, Luciana Musetti, Hans Klompen, Andrew Polaszek, Lubomír Masner, Andrew D. Austin & Norman F. Johnson
The superfamily Platygastroidea (Hymenoptera: Proctotrupomorpha) is a diverse group of parasitoid wasps that attack nine orders of insects as well as spiders. They appear to show a clear pattern of host group specificity among genera. A robust phylogeny is essential to understanding the monophyly of and relationships among lower level groups and the pattern of the shifts among host groups. We conducted phylogenetic analyses of Platygastroidea based on four molecular markers (18S, 28S, COI, and...

Calibrating phylogenies assuming bifurcation or budding alters inferred macroevolutionary dynamics in a densely sampled phylogeny of bivalve families

Nicholas Crouch, Stewart Edie, Katie Collins, Rüdiger Bieler & David Jablonski
Analyses of evolutionary dynamics can be profoundly affected by age calibrations of phylogenetic nodes under different models of lineage branching. Most time-calibrated molecular phylogenies of extant taxa assume a purely bifurcating model, where nodes are calibrated using the daughter lineage with the older first occurrence in the fossil record. Lineages can also split via budding, in which a parent lineage persists following the origin of a daughter lineage, and nodes are calibrated using the age...

A reassessment of the enigmatic diapsid Paliguana whitei and the early history of Lepidosauromorpha

David Paul Ford, Susan Evans, Jonah Choiniere, Vincent Fernandez & Roger Benson
Lepidosaurs include lizards, snakes, amphisbaenians and the tuatara, comprising a highly speciose evolutionary radiation with widely varying anatomical traits. Their stem-lineage originated by the late middle Permian 259 million years ago, but its early fossil record is poorly documented, obscuring the origins of key anatomical and functional traits of the group. Paliguana whitei, from the Early Triassic of South Africa, is an enigmatic fossil species with potential to provide information on this. However, its anatomy...

Hearing from the ocean and into the river: The evolution of the inner ear of Platanistoidea (Cetacea, Odontoceti)

Mariana Viglino, Maximiliano Gaetán, Mónica R. Buono, R. Ewan Fordyce & Travis Park
The inner ear of the two higher clades of modern cetaceans (Neoceti) is highly adapted for hearing infrasonic (mysticetes) or ultrasonic (odontocetes) frequencies. Within odontocetes, Platanistoidea comprises a single extant riverine representative, Platanista gangetica, and a diversity of mainly extinct marine species from the late Oligocene onward. Recent studies, drawing on features including the disparate tympanoperiotic, have not yet provided a consensus phylogenetic hypothesis for platanistoids. Further, cochlear morphology and evolutionary patterns have never been...

Evolution, diversity, and disparity of the tiger shark lineage Galeocerdo in deep time

Julia Türtscher, Faviel A. López-Romero, Patrick L. Jambura, René Kindlimann, David J. Ward & Jürgen Kriwet
Sharks have a long and rich fossil record that consists predominantly of isolated teeth due to the poorly mineralized cartilaginous skeleton. Tiger sharks (Galeocerdo), which represent apex predators in modern oceans, have a known fossil record extending back into the early Eocene (ca. 56 Ma) and comprise 22 recognised extinct and one extant species to date. However, many of the fossil species remain dubious, resulting in a still unresolved evolutionary history of the tiger shark...
