Data from: Malagasy cichlids differentially limit impacts of body shape evolution on oral jaw functional morphology

Christopher M. Martinez & John Steven Sparks
Patterns of trait covariation, like integration and modularity, are vital factors that influence the evolution of vertebrate body plans. In functional systems, decoupling of morphological modules buffers functional change in one trait by reducing correlated variation with another. However, for complex morphologies with many-to-one mapping of form to function (MTOM), resistance to functional change may also be achieved by constraining morphological variation within a functionally stable region of morphospace. For this research, we used geometric...

Data from: Cladogenetic and anagenetic models of chromosome number evolution: a Bayesian model averaging approach

William A. Freyman, Sebastian Höhna & William A Freyman
Chromosome number is a key feature of the higher-order organization of the genome, and changes in chromosome number play a fundamental role in evolution. Dysploid gains and losses in chromosome number, as well as polyploidization events, may drive reproductive isolation and lineage diversification. The recent development of probabilistic models of chromosome number evolution in the groundbreaking work by Mayrose et al. (2010, ChromEvol) have enabled the inference of ancestral chromosome numbers over molecular phylogenies and...

Data from: Declines in low-elevation subalpine tree populations outpace growth in high-elevation populations with warming

Erin Conlisk, Cristina Castanha, Matthew J. Germino, Thomas T. Veblen, Jeremy M. Smith & Lara M. Kueppers
1. Species distribution shifts in response to climate change require that recruitment increase beyond current range boundaries. For trees with long lifespans, the importance of climate-sensitive seedling establishment to the pace of range shifts has not been demonstrated quantitatively. 2. Using spatially explicit, stochastic population models combined with data from long-term forest surveys, we explored whether the climate-sensitivity of recruitment observed in climate manipulation experiments was sufficient to alter populations and elevation ranges of two...

Data from: Measuring β‐diversity by remote sensing: a challenge for biodiversity monitoring

Duccio Rocchini, Sandra Luque, Nathalie Pettorelli, Lucy Bastin, Daniel Doktor, Nicolò Faedi, Hannes Feilhauer, Jean-Baptiste Féret, Giles M. Foody, Yoni Gavish, Sergio Godinho, William E. Kunin, Angela Lausch, Pedro J. Leitao, Matteo Marcantonio, Markus Neteler, Carlo Ricotta, Sebastian Schmidtlein, Petteri Vihervaara, Martin Wegmann & Harini Nagendra
Biodiversity includes multiscalar and multitemporal structures and processes, with different levels of functional organization, from genetic to ecosystemic levels. One of the mostly used methods to infer bio- diversity is based on taxonomic approaches and community ecology theories. However, gathering extensive data in the field is difficult due to logistic problems, especially when aiming at modelling biodiversity changes in space and time, which assumes statistically sound sampling schemes. In this context, airborne or satellite remote...

Data from: Pleistocene climatic fluctuations drive isolation and secondary contact in the red diamond rattlesnake (Crotalus ruber) in Baja California

Sean M. Harrington, Bradford D. Hollingsworth, Timothy E. Higham & Tod W. Reeder
Aim: Many studies have investigated the phylogeographic history of species on the Baja California Peninsula, and they often show one or more genetic breaks that are spatially concordant among many taxa. These phylogeographic breaks are commonly attributed to vicariance as a result of geological or climatic changes, followed by secondary contact when barriers are no longer present. We use restriction-site associated DNA sequence data and a phylogeographic model selection approach to explicitly test the secondary...

Data from: Residential development alters behavior, movement, and energetics in an apex predator, the puma

Yiwei Wang, Justine A. Smith & Christopher C. Wilmers
Human development strongly influences large carnivore survival and persistence globally. Behavior changes are often the first measureable responses to human disturbances, and can have ramifications on animal populations and ecological communities. We investigated how a large carnivore responds to anthropogenic disturbances by measuring activity, movement behavior, and energetics in pumas along a housing density gradient. We used log-linear analyses to examine how habitat, time of day, and proximity to housing influenced the activity patterns of...

Data from: Theory, practice, and conservation in the age of genomics: the Galápagos giant tortoise as a case study

Stephen J. Gaughran, Maud C. Quinzin, Joshua M. Miller, Ryan C. Garrick, Danielle L. Edwards, Michael A. Russello, Nikos Poulakakis, Claudio Ciofi, Luciano B. Beheregaray, Aldalgisa Caccone & Adalgisa Caccone
Hgh-throughput DNA sequencing allows efficient discovery of thousands of single nucleotide polymorphisms (SNPs) in non-model species. Population genetic theory predicts that this large number of independent markers should provide detailed insights into population structure, even when only a few individuals are sampled. Still, sampling design can have a strong impact on such inferences. Here, we use simulations and empirical SNP data to investigate the impacts of sampling design on estimating genetic differentiation among populations that...

Data from: Genetic coupling of female mate choice with polygenic ecological divergence facilitates stickleback speciation

Rachael A. Bay, Matthew E. Arnegard, Gina L. Conte, Jacob Best, Nicole L. Bedford, Shaugnessy R. McCann, Matthew E. Dubin, Yingguang Frank Chan, Felicity C. Jones, David M. Kingsley, Dolph Schluter & Catherine L. Peichel
Ecological speciation with gene flow is widespread in nature, but it presents a conundrum: how are associations between traits under divergent natural selection and traits that contribute to assortative mating maintained? Theoretical models suggest that genetic mechanisms inhibiting free recombination between loci underlying these two types of traits (hereafter, “genetic coupling”) can facilitate speciation. Here, we perform a direct test for genetic coupling by mapping both divergent traits and female mate choice in a classic...

Data from: Seasonal variation in daily patterns of social contacts in the European badger Meles meles

Matthew J. Silk, Nicola Weber, Lucy C. Steward, Richard J. Delahay, Darren P. Croft, David J. Hodgson, Mike Boots & Robbie A. McDonald
Social interactions among hosts influence the persistence and spread of infectious pathogens. Daily and seasonal variation in the frequency and type of social interactions will play an important role in disease epidemiology and, alongside other factors, may have an influence on wider disease dynamics by causing seasonal forcing of infection, especially if the seasonal variation experienced by a population is considerable. We explored temporal variation in within-group contacts in a high-density population of European badgers...

Data from: Trait-dependent distributional shifts in fruiting of common British fungi

Alan C. Gange, Einar Heegaard, Lynne Boddy, Carrie Andrew, Paul Kirk, Rune Halvorsen, Thomas W. Kuyper, Claus Bässler, Jeffrey Diez, Jacob Heilman-Clausen, Klaus Høiland, Ulf Büntgen & Håvard Kauserud
Despite the dramatic phenological responses of fungal fruiting to recent climate warming, it is unknown whether spatial distributions of fungi have changed and to what extent such changes are influenced by fungal traits, such as ectomycorrhizal (ECM) or saprotrophic lifestyles, spore characteristics, or fruit body size. Our overall aim was to understand how climate and fungal traits determine whether and how species-specific fungal fruit body abundances have shifted across latitudes over time, using the UK...

Data from: Range instability leads to cytonuclear discordance in a morphologically cryptic ground squirrel species complex

Mark A. Phuong, Ke Bi & Craig Moritz
The processes responsible for cytonuclear discordance frequently remain unclear. Here, we employed an exon capture dataset and demographic methods to test hypotheses generated by species distribution models to examine how contrasting histories of range stability vs. fluctuation have caused cytonuclear concordance and discordance in ground squirrel lineages from the Otospermophilus beecheyi species complex. Previous studies in O. beecheyi revealed three morphologically cryptic and highly divergent mitochondrial DNA lineages (named the Northern, Central, and Southern lineages...

Data from: A new genus of horse from Pleistocene North America

Peter D. Heintzman, Grant D. Zazula, Ross D.E. MacPhee, Eric Scott, James A. Cahill, Brianna K. McHorse, Joshua D. Kapp, Mathias Stiller, Matthew J. Wooller, Ludovic Orlando, John R. Southon, Duane G. Froese, Beth Shapiro, Matthew J Wooller, Duane G Froese, Brianna K McHorse, Peter D Heintzman, James A Cahill, Joshua D Kapp & John Southon
The extinct “New World stilt-legged”, or NWSL, equids constitute a perplexing group of Pleistocene horses endemic to North America. Their slender distal limb bones resemble those of Asiatic asses, such as the Persian onager. Previous palaeogenetic studies, however, have suggested a closer relationship to caballine horses than to Asiatic asses. Here, we report complete mitochondrial and partial nuclear genomes from NWSL equids from across their geographic range. Although multiple NWSL equid species have been named,...

Data from: Seed origin and warming constrain lodgepole pine recruitment, slowing the pace of population range shifts

Erin Conlisk, Cristina Castanha, Matthew J. Germino, Thomas T. Veblen, Jeremy M. Smith, Andrew B. Moyes & Lara M. Kueppers
Understanding how climate warming will affect the demographic rates of different ecotypes is critical to predicting shifts in species distributions. Here we present results from a common garden, climate change experiment in which we measured seedling recruitment of lodgepole pine, a widespread North American conifer that is also planted globally. Seeds from a low-elevation provenance had greater recruitment to their third year (by 323%) than seeds from a high-elevation provenance across sites within and above...

Data from: Herbivores alter plant-wind interactions by acting as a point mass on leaves and by removing leaf tissue

Adit R. Kothari & Nicholas P. Burnett
In nature, plants regularly interact with herbivores and with wind. Herbivores can wound and alter the structure of plants, whereas wind can exert aerodynamic forces that cause the plants to flutter or sway. While herbivory has many negative consequences for plants, fluttering in wind can be beneficial for plants by facilitating gas exchange and loss of excess heat. Little is known about how herbivores affect plant motion in wind. We tested how the mass of...

Data from: Discovery and characterization of single nucleotide polymorphisms in two anadromous alosine fishes of conservation concern

Diana S. Baetscher, Daniel J. Hasselman, Kerry Reid, Eric P. Palkovacs & John Carlos Garza
Freshwater habitat alteration and marine fisheries can affect anadromous fish species, and populations fluctuating in size elicit conservation concern and coordinated management. We describe the development and characterization of two sets of 96 single nucleotide polymorphism (SNP) assays for two species of anadromous alosine fishes, alewife and blueback herring (collectively known as river herring), that are native to the Atlantic coast of North America. We used data from high-throughput DNA sequencing to discover SNPs and...

Data from: Early-branching euteleost relationships: areas of congruence between concatenation and coalescent model inferences

Matthew A. Campbell, Michael E. Alfaro, Max Belasco & J. Andrés López
Phylogenetic inference based on evidence from DNA sequences has led to significant strides in the development of a stable and robustly supported framework for the vertebrate tree of life. To date, the bulk of those advances have relied on sequence data from a small number of genome regions that have proven unable to produce satisfactory answers to consistently recalcitrant phylogenetic questions. Here, we re-examine phylogenetic relationships among early-branching euteleostean fish lineages classically grouped in the...

Data from: Repeated evolution of vertebrate pollination syndromes in a recently diverged Andean plant clade

Laura P. Lagomarsino, Elisabeth J. Forrestel, Nathan Muchhala & Charles C. Davis
While specialized interactions, including those involving plants and their pollinators, are often invoked to explain high species diversity, they are rarely explored at macroevolutionary scales. We investigate the dynamic evolution of hummingbird and bat pollination syndromes in the centropogonid clade (Lobelioideae: Campanulaceae), an Andean-centered group of ∼550 angiosperm species. We demonstrate that flowers hypothesized to be adapted to different pollinators based on flower color fall into distinct regions of morphospace, and this is validated by...

Data from: Metagenomic sequencing detects respiratory pathogens in hematopoietic cellular transplant patients

Charles Langelier, Matt S. Zinter, Katrina K. Kalantar, Gregory A. Yanik, Stephanie Christenson, Brian O'Donovan, Corin C. White, Anil Sapru, Christopher C. Dvorak, Steve Miller, Charles Y. Chiu, Joseph L. DeRisi, Katrina Kalantar, Corin White & Michael Wilson
Rationale: Current microbiologic diagnostics often fail to identify the etiology of lower respiratory tract infections (LRTI) in hematopoietic cellular transplant recipients (HCT), which precludes the implementation of targeted therapies. Objectives: To address the need for improved LRTI diagnostics, we evaluated the utility of metagenomic next generation sequencing (mNGS) of bronchoalveolar lavage (BAL) to detect microbial pathogens in HCT patients with acute respiratory illnesses. Methods: We enrolled 22 post-HCT adults ages 19-69 years with acute respiratory...

Data from: Correlated evolution between colouration and ambush site in predators with visual prey lures

Felipe Malheiros Gawryszewski, Miguel A. Calero-Torralbo, Rosemary Gillespie, Miguel Rodriguez-Girones, Marie E. Herberstein, Felipe M. Gawryszewski & Rosemary G. Gillespie
The evolution of a visual signal will be affected by signaller and receiver behaviour, and by the physical properties of the environment where the signal is displayed. Crab spiders are typical sit-and-wait predators found in diverse ambush sites, such as tree bark, foliage and flowers. Some of the flower-dweller species present a UV+-white visual lure that makes them conspicuous and attractive to their prey. We hypothesised that UV+-white colouration was associated with the evolution of...

Data from: Vegetation response to control of invasive Tamarix in southwestern US rivers: a collaborative study including 416 sites

Eduardo González, Anna A. Sher, Robert M. Anderson, Robin F. Bay, Daniel W. Bean, Gabriel J. Bissonnete, Bérenger Bourgeois, David J. Cooper, Kara Dohrenwend, Kim D. Eichhorst, Hisham El Waer, Deborah K. Kennard, Rebecca Harms-Weissinger, Annie L. Henry, Lori J. Makarick, Steven M. Ostoja, Lindsay V. Reynolds, W. Wright Robinson & Patrick B. Shafroth
Most studies assessing vegetation response following control of invasive Tamarix trees along southwestern U.S. rivers have been small in scale (e.g., river reach), or at a regional scale but with poor spatial-temporal replication, and most have not included testing the effects of a now widely-used biological control. We monitored plant composition following Tamarix control along hydrologic, soil and climatic gradients in 244 treated and 172 reference sites across six U.S. States. This represents the largest...

Data from: Habitat filtering determines the functional niche occupancy of plant communities worldwide

Yuanzhi Li, Bill Shipley, Jodi N. Price, Vinícius De L. Dantas, Riin Tamme, Mark Westoby, Andrew Siefert, Brandon S. Schamp, Marko J. Spasojevic, Vincent Jung, Daniel C. Laughlin, Sarah J. Richardson, Yoann Le Bagousse-Pinguet, Christian Schöb, Antonio Gazol, Honor C. Prentice, Nicolas Gross, Jacob Overton, Marcus V. Cianciaruso, Frédérique Louault, Chiho Kamiyama, Tohru Nakashizuka, Kouki Hikosaka, Takehiro Sasaki, Masatoshi Katabuchi … & Yoann Le Bagousse-Pinguet
How the patterns of niche occupancy vary from species-poor to species-rich communities is a fundamental question in ecology that has a central bearing on the processes that drive patterns of biodiversity. As species richness increases, habitat filtering should constrain the expansion of total niche volume, while limiting similarity should restrict the degree of niche overlap between species. Here, by explicitly incorporating intraspecific trait variability, we investigate the relationship between functional niche occupancy and species richness...

Data from: Genetic and individual assignment of tetraploid green sturgeon with SNP assay data

Eric C. Anderson, Thomas C. Ng, Eric D. Crandall & John Carlos Garza
Polyploid organisms pose substantial obstacles to genetic analysis, as molecular assay data are usually difficult to evaluate in a Mendelian framework. Green sturgeon (Acipenser medirostris) is a tetraploid species and is facing significant conservation challenges, including bycatch in ocean fisheries. We present here novel molecular genetic assays and analytical methodology for green sturgeon that allow discrimination of fish from the two visually indistinguishable distinct population segments (DPSs), and also provide individual-specific genetic tags. We show...

Data from: Atoll-scale patterns in coral reef community structure: Human signatures on Ulithi Atoll, Micronesia

Nicole L. Crane, Peter Nelson, Avigdor Abelson, Kristin Precoda, Rulmal Jr., John, Giacomo Bernardi & Michelle Paddack
The dynamic relationship between reefs and the people who utilize them at a subsistence level is poorly understood. This paper characterizes atoll-scale patterns in shallow coral reef habitat and fish community structure, and correlates these with environmental characteristics and anthropogenic factors, critical to conservation efforts for the reefs and the people who depend on them. Hierarchical clustering analyses by site for benthic composition and fish community resulted in the same 3 major clusters: cluster 1–oceanic...

Data from: The evolution of feather coloration and song in Old World orioles (genus Oriolus)

Beata Matysiokova, Nicholas Friedman, Lucia Turčoková & Vladimir Remes
What is the tempo and mode of evolution – how fast and in what pattern do traits evolve – is a major question of evolutionary biology. Here we studied patterns of evolutionary change in visual and acoustic signals in Old World orioles. Since producing multiple signals may be costly, we also tested whether there was an evolutionary trade-off between the elaboration of those two types of signals. We studied 30 Oriolus taxa using comparative methods...

Data from: Integrating lipid storage into general representations of fish energetics

Benjamin T. Martin, Ron Heintz, Eric M. Danner & Roger M. Nisbet
Fish, even of the same species, can exhibit substantial variation in energy density (energy per unit wet weight). Most of this variation is due to differences in the amount of storage lipids. In addition to their importance as energy reserves for reproduction and for survival during unfavourable conditions, the accumulation of lipids represents a large energetic flux for many species, so figuring out how this energy flux is integrated with other major energy fluxes (growth,...
