Data from: Local endemism and within-island diversification of shrews illustrate the importance of speciation in building Sundaland mammal diversity

Terrence C. Demos, Anang S. Achmadi, Thomas C. Giarla, Heru Handika, , Kevin C. Rowe & Jacob A. Esselstyn
Island systems are important models for evolutionary biology because they provide convenient, discrete biogeographic units of study. Continental islands with a history of intermittent dry land connections confound the discrete definitions of islands and have led zoologists to predict (1) little differentiation of terrestrial organisms among continental shelf islands and (2) extinction, rather than speciation, to be the main cause of differences in community composition among islands. However, few continental island systems have been subjected...

Data from: Serological evidence of lyssaviruses among bats on southwestern Indian Ocean islands

Julien Mélade, Stewart McCulloch, Beza Ramasindrazana, Erwan Lagadec, Magali Turpin, Hervé Pascalis, Steven M. Goodman, Wanda Markotter & Koussay Dellagi
We provide serological evidence of lyssavirus circulation among bats on southwestern Indian Ocean (SWIO) islands. A total of 572 bats belonging to 22 species were collected on Anjouan, Mayotte, La Réunion, Mauritius, Mahé and Madagascar and screened by the Rapid Fluorescent Focus Inhibition Test for the presence of neutralising antibodies against the two main rabies related lyssaviruses circulating on the African continent: Duvenhage lyssavirus (DUVV) and Lagos bat lyssavirus (LBV), representing phylogroups I and II,...

Data from: Comparative genomics reveals convergent rates of evolution in ant-plant mutualisms

Benjamin E. R. Rubin & Corrie S. Moreau
Symbiosis—the close and often long-term interaction of species—is predicted to drive genome evolution in a variety of ways. For example, parasitic interactions have been shown to increase rates of molecular evolution, a trend generally attributed to the Red Queen Hypothesis. However, it is much less clear how mutualisms impact the genome, as both increased and reduced rates of change have been predicted. Here we sequence the genomes of seven species of ants, three that have...

Data from: Early and dynamic colonization of Central America drives speciation in Neotropical army ants

Max E. Winston, Daniel J. C. Kronauer & Corrie S. Moreau
The emergence of the Isthmus of Panama is one of the most important events in recent geological history, yet its timing and role in fundamental evolutionary processes remain controversial. While the formation of the isthmus was complete around 3 million years ago (Ma), recent studies have suggested prior intercontinental biotic exchange. In particular, the possibility of early intermittent land bridges facilitating colonization constitutes a potential mechanism for speciation and colonization before full closure of the...

Data from: Defensive traits exhibit an evolutionary trade-off and drive diversification in ants

Benjamin D. Blanchard & Corrie S. Moreau
Evolutionary biologists have long predicted that evolutionary trade-offs among traits should constrain morphological divergence and species diversification. However, this prediction has yet to be tested in a broad evolutionary context in many diverse clades, including ants. Here, we reconstruct an expanded ant phylogeny representing 82% of ant genera, compile a new family-wide trait database, and conduct various trait-based analyses to show that defensive traits in ants do exhibit an evolutionary trade-off. In particular, the use...

Data from: A complete molecular phylogeny of Claravis confirms its paraphyly within small New World ground-doves (Aves: Peristerinae) and implies multiple plumage state transitions

Andrew D. Sweet, J. Dylan Maddox & Kevin P. Johnson
The three species in the genus Claravis (Aves: Peristerinae) are unique among members of the small New World ground-dove clade. All three species inhabit forested areas rather than open scrubby habitat, and exhibit obvious sexual dichromatism. However, the phylogenetic relationships within Claravis remain unknown. The only molecular phylogenetic study to include more than one species of Claravis indicated the genus is paraphyletic. Here we include molecular data from all three Claravis species, including sequences from...

Data from: The ecology of a continental evolutionary radiation: Is the radiation of sigmodontine rodents adaptive?

Renan Maestri, Leandro Rabello Monteiro, Rodrigo Fornel, Nathan S. Upham, Bruce D. Patterson & Thales Renato Ochotorena De Freitas
Evolutionary radiations on continents are less well-understood and appreciated than those occurring on islands. The extent of ecological influence on species divergence can be evaluated to determine whether a radiation was ultimately the outcome of divergent natural selection or else arose mainly by nonecological divergence. Here, we used phylogenetic comparative methods to test distinct hypotheses corresponding to adaptive and nonadaptive evolutionary scenarios for the morphological evolution of sigmodontine rodents. Results showed that ecological variables (diet...

Data from: Limitations of species delimitation based on phylogenetic analyses: a case study in the (Hypogymnia hypotrypa) group (Parmeliaceae, Ascomycota)

Xinli Wei, Bruce McCune, H. Thorsten Lumbsch, Hui Li, Steven Leavitt, Yoshikazu Yamamoto, Svetlana Tchabanenko & Jiangchun Wei
Delimiting species boundaries among closely related lineages often requires a range of independent data sets and analytical approaches. Similar to other organismal groups, robust species circumscriptions in fungi are increasingly investigated within an empirical framework. Here we attempt to delimit species boundaries in a closely related clade of lichen-forming fungi endemic to Asia, the Hypogymnia hypotrypa group (Parmeliaceae). In the current classification, the Hypogymnia hypotrypa group includes two species: H. hypotrypa and H. flavida, which...

Data from: Social selection parapatry in Afrotropical sunbirds

Jay P. McEntee, Joshua V. Peñalba, Chacha Werema, Elia Mulungu, Maneno Mbilinyi, David Moyer, Louis Hansen, Jon Fjeldså & Rauri C. K. Bowie
The extent of range overlap of incipient and recent species depends on the type and magnitude of phenotypic divergence that separates them, and the consequences of phenotypic divergence on their interactions. Signal divergence by social selection likely initiates many speciation events, but may yield niche-conserved lineages predisposed to limit each others’ ranges via ecological competition. Here we examine this neglected aspect of social selection speciation theory in relation to the discovery of a non-ecotonal species...

Data from: Global population genetic dynamics of a highly migratory, apex predator shark

Andrea M. Bernard, Kevin A. Feldheim, Michael R. Heithaus, Sabine P. Wintner, Bradley M. Wetherbee & Mahmood S. Shivji
Knowledge of genetic connectivity dynamics in the world's large-bodied, highly migratory, apex predator sharks across their global ranges is limited. One such species, the tiger shark (Galeocerdo cuvier), occurs worldwide in warm temperate and tropical waters, uses remarkably diverse habitats (nearshore to pelagic) and possesses a generalist diet that can structure marine ecosystems through top-down processes. We investigated the phylogeography and the global population structure of this exploited, phylogenetically enigmatic shark by using 10 nuclear...

Data from: Phylogenetic stability, tree shape, and character compatibility: a case study using early tetrapods

Massimo Bernardi, Kenneth D. Angielczyk, Jonathan S. Mitchell & Marcello Ruta
Phylogenetic tree shape varies as the evolutionary processes affecting a clade change over time. In this study, we examined an empirical phylogeny of fossil tetrapods during several time intervals, and studied how temporal constraints manifested in patterns of tree imbalance and character change. The results indicate that the impact of temporal constraints on tree shape is minimal and highlights the stability through time of the reference tetrapod phylogeny. Unexpected values of imbalance for Mississippian and...

Data from: Phylogeography and species delimitation in convict cichlids (Cichlidae: Amatitlania): implications for taxonomy and Plio–Pleistocene evolutionary history in Central America

Justin C. Bagley, Wilfredo A. Matamoros, Caleb D. McMahan, Michael Tobler, Prosanta Chakrabarty & Jerald B. Johnson
We investigate phylogeographic patterns and delimit species boundaries within Amatitlania, a genus of Central American cichlid fishes. Phylogenetic analyses of mitochondrial DNA sequences from 318 individuals spanning the geographical ranges of all three currently recognized Amatitlania species strongly supported one major clade, with a relatively diverged subclade corresponding to A. kanna samples from eastern Costa Rica and Panama. Gene trees and networks revealed marked incongruences between phylogeographic structure and morpho-species taxonomy as a result of...
