Data from: Evaluation of Blue Crab, Callinectes sapidus, megalopal settlement and condition during the Deepwater Horizon oil spill

Erin K. Grey, Susan C. Chiasson, Hannah G. Williams, Victoria J. Troeger & Caz M. Taylor
The Blue Crab, Callinectes sapidus, is a commercially, culturally, and ecologically significant species in the Gulf of Mexico (GOM), whose offshore stages were likely impacted by the Deepwater Horizon oil spill (DWH). To test for DWH effects and to better understand the planktonic ecology of this species, we monitored Callinectes spp. megalopal settlement and condition at sites within and outside of the spill extent during and one year after the DWH. We tested for DWH...

Data from: New mud turtles (Kinosternidae, Kinosternon) from the Middle-Late Miocene of the United States

Jason R. Bourque
Kinosternon Spix, 1824, was widespread in xeric to savanna associated paleowetlands across North America during the middle–late Miocene and steadily diversified following its first occurrences in the Hemingfordian. In the middle Miocene, Kinosternon rincon n. sp. occurred in the late Barstovian Cerro Conejo Formation of north central New Mexico, perhaps concurrently with Kinosternon pojoaque Bourque 2012a from the Tesuque Formation. Subsequent late Miocene kinosternine fossils indicate that at least three potentially contemporaneous species existed throughout...

Data from: Moth tails divert bat attack: evolution of acoustic deflection

Jesse R. Barber, Brian C. Leavell, Adam L. Keener, Jesse W. Breinholt, Brad A. Chadwell, Christopher J.W. McClure, Geena M. Hill & Akito Y. Kawahara
Adaptations to divert the attacks of visually guided predators have evolved repeatedly in animals. Using high-speed infrared videography, we show that luna moths (Actias luna) generate an acoustic diversion with spinning hindwing tails to deflect echolocating bat attacks away from their body and toward these nonessential appendages. We pit luna moths against big brown bats (Eptesicus fuscus) and demonstrate a survival advantage of ∼47% for moths with tails versus those that had their tails removed....

Data from: Assessing reproductive behavior important to fisheries management: a case study with red drum, Sciaenops ocellatus

Susan K. Lowerre-Barbieri, Sarah Lyle Walters Burnsed & Joel William Bickford
Spawning site selection and reproductive timing affect stock productivity and structure in marine fishes but are poorly understood. Traditionally, stock assessments measure reproductive potential as spawning stock biomass or egg production and do not include other aspects of reproductive behavior. Red drum make an excellent case study to assess these other aspects, as (1) they are highly fecund, pelagic spawners, like most exploited marine fishes; (2) their life cycle is delineated between nursery (estuarine) and...

Data from: Raccoon contact networks predict seasonal susceptibility to rabies outbreaks and limitations of vaccination

Jennifer J. H. Reynolds, Ben T. Hirsch, Stanley D. Gehrt & Meggan E. Craft
1. Infectious disease transmission often depends on the contact structure of host populations. Although it is often challenging to capture the contact structure in wild animals, new technology has enabled biologists to obtain detailed temporal information on wildlife social contacts. In this study, we investigated the effects of raccoon contact patterns on rabies spread using network modelling. 2. Raccoons (Procyon lotor) play an important role in the maintenance of rabies in the United States. It...

Data from: Conservation under uncertainty: optimal network protection strategies for worst-case disturbance events

Miguel A. Acevedo, Jorge A. Sefair, J. Cole Smith, , Brian Reichert & Robert J. Fletcher
1. Conservation goals are ideally set after a thorough understanding of potential threats; however, predicting future spatial patterns of threats, such as disturbance, remains challenging. Here, we develop a novel extension of network fortification-interdiction models (NFIM) that deals with uncertainty in future spatial patterns of disturbance by optimally selecting sites that will best mitigate a worst-case scenario for a given magnitude of disturbance. 2. This approach uses information on between-patch movement probabilities and patch-specific survival,...

Data from: Comparing process-based and constraint-based approaches for modeling macroecological patterns

Xiao Xiao, James P. O'Dwyer & Ethan P. White
Ecological patterns arise from the interplay of many different processes, and yet the emergence of consistent phenomena across a diverse range of ecological systems suggests that many patterns may in part be determined by statistical or numerical constraints. Differentiating the extent to which patterns in a given system are determined statistically, and where it requires explicit ecological processes, has been difficult. We tackled this challenge by directly comparing models from a constraint-based theory, the Maximum...

Data from: Tempo and mode of antibat ultrasound production and sonar jamming in the diverse hawkmoth radiation

Akito Y. Kawahara & Jesse R. Barber
The bat–moth arms race has existed for over 60 million y, with moths evolving ultrasonically sensitive ears and ultrasound-producing organs to combat bat predation. The evolution of these defenses has never been thoroughly examined because of limitations in simultaneously conducting behavioral and phylogenetic analyses across an entire group. Hawkmoths include >1,500 species worldwide, some of which produce ultrasound using genital stridulatory structures. However, the function and evolution of this behavior remain largely unknown. We built...

Data from: Resolving basal lamiid phylogeny and the circumscription of Icacinaceae with a plastome-scale data set

Gregory W. Stull, Rodrigo Duno De Stefano, Douglas E. Soltis & Pamela S. Soltis
PREMISE OF THE STUDY: Major relationships within Lamiidae, an asterid clade with ∼40000 species, have largely eluded resolution despite two decades of intensive study. The phylogenetic positions of Icacinaceae and other early-diverging lamiid clades (Garryales, Metteniusaceae, and Oncothecaceae) have been particularly problematic, hindering classification and impeding our understanding of early lamiid (and euasterid) character evolution. METHODS: To resolve basal lamiid phylogeny, we sequenced 50 plastid genomes using the Illumina sequencing platform and combined these with...

Data from: Regional variation in Caribbean dry forest tree species composition

Janet Franklin, Julie Ripplinger, Ethan H. Freid, Humfredo Marcano-Vega & David W. Steadman
How does tree species composition vary in relation to geographical and environmental gradients in a globally rare tropical/subtropical broadleaf dry forest community in the Caribbean? We analyzed data from 153 Forest Inventory and Analysis (FIA) plots from Puerto Rico and the U.S. Virgin Islands (USVI), along with 42 plots that we sampled in the Bahamian Archipelago (on Abaco and Eleuthera Islands). FIA data were collected using published protocols. In the Bahamian Archipelago, we recorded terrain...

Data from: The influence of host plant extrafloral nectaries on multitrophic interactions: an experimental investigation

Suzanne Koptur, Ian M. Jones & Jorge E. Peña
A field experiment was conducted with outplantings of the native perennial shrub Senna mexicana var. chapmanii in a semi-natural area adjacent to native pine rockland habitat in southern Florida. The presence of ants and the availability of extrafloral nectar were manipulated in a stratified random design. Insect communities were monitored and recorded over a period of six months with a view to addressing three main questions. Do ants provide biotic defense against key herbivores on...

Data from: Character evolution and the origin of Caimaninae (Crocodylia) in the New World Tropics: new evidence from the Miocene of Panama and Venezuela

Alexander K. Hastings, Moritz Reisser & Torsten M. Scheyer
Alligators and caimans share a close relationship, supported by both molecular and morphological characters. The divergence between alligators and caimans has been difficult to discern in the fossil record. Two basal taxa have recently been described from the Miocene of Panama and Venezuela but have not yet been presented in a joint phylogeny. Continued preparation of the type material of the Venezuelan Globidentosuchus brachyrostris Scheyer et al., 2013 has revealed new characters for scoring in...

Data from: Fire and non-native grass invasion interact to suppress tree regeneration in temperate deciduous forests

S. Luke Flory, Keith Clay, Sarah M. Emery, Joseph R. Robb & Brian Winters
1. While many ecosystems depend on fire to maintain biodiversity, non-native plant invasions can enhance fire intensity, suppressing native species and generating a fire–invasion feedback. These dynamics have been observed in arid and semi-arid ecosystems, but fire–invasion interactions in temperate deciduous forests, where prescribed fires are often used as management tools to enhance native diversity, have rarely been investigated. 2. Here we evaluated the effects of a widespread invasive grass on fire behaviour in eastern...

Data from: Environmental and scale-dependent evolutionary trends in the body size of crustaceans

Adiël A. Klompmaker, Carrie E. Schweitzer, Rodney M. Feldmann & Michał Kowalewski
The ecological and physiological significance of body size is well recognized. However, key macroevolutionary questions regarding the dependency of body size trends on the taxonomic scale of analysis and the role of environment in controlling long-term evolution of body size are largely unknown. Here, we evaluate these issues for decapod crustaceans, a group that diversified in the Mesozoic. A compilation of body size data for 792 brachyuran crab and lobster species reveals that their maximum,...

Data from: Can butterflies evade fire? Pupa location and heat tolerance in fire prone habitats of Florida

Matthew D. Thom, Jaret C. Daniels, Leda N. Kobziar & Jonathan R. Colburn
Butterflies such as the atala hairstreak, Eumaeus atala Poey, and the frosted elfin, Callophrys irus Godart, are restricted to frequently disturbed habitats where their larval host plants occur. Pupae of these butterflies are noted to reside at the base of host plants or in the leaf litter and soil, which may allow them to escape direct mortality by fire, a prominent disturbance in many areas they inhabit. The capacity of these species to cope with...

Worldwide evidence of a unimodal relationship between productivity and plant species richness

Lauchlan H. Fraser, Jason Pither, Anke Jentsch, Marcelo Sternberg, Martin Zobel, Diana Askarizadeh, Sandor Bartha, Carl Beierkuhnlein, Jonathan A. Bennett, Alex Bittel, Bazartseren Boldgiv, Ilsi I. Boldrini, Edward Bork, Leslie Brown, Marcelo Cabido, James Cahill, Cameron N. Carlyle, Giandiego Campetella, Stefano Chelli, Ofer Cohen, Anna-Maria Csergo, Sandra Diaz, Lucas Enrico, David Ensing, Alessandra Fidelis … & Szilárd Szentes
The search for predictions of species diversity across environmental gradients has challenged ecologists for decades. The humped-back model (HBM) suggests that plant diversity peaks at intermediate productivity; at low productivity few species can tolerate the environmental stresses, and at high productivity a few highly competitive species dominate. Over time the HBM has become increasingly controversial, and recent studies claim to have refuted it. Here, by using data from coordinated surveys conducted throughout grasslands worldwide and...

Data from: Building the avian tree of life using a large-scale, sparse supermatrix

J. Gordon Burleigh, Rebecca T. Kimball & Edward L. Braun
Birds are the most diverse tetrapod class, with about 10,000 extant species that represent a remarkable evolutionary radiation in which most taxa arose during a short period of time. There has been a tremendous increase in the amount of molecular data available from birds, and more than two-thirds of these species have some sequence data available. Here we assembled these available sequence data from birds to estimate a large-scale avian phylogeny. We performed an unconstrained...

Data from: Inhibition of BTK and ITK with ibrutinib is effective in the prevention of chronic graft-versus-host disease in mice

Steven D. Schutt, Jianing Fu, Hung Nguyen, David Bastian, Jessica Heinrichs, Yongxia Wu, Chen Liu, Daniel G. McDonald, Joseph Pidala & Xue-Zhong Yu
Bruton’s Tyrosine Kinase (BTK) and IL-2 Inducible T-cell Kinase (ITK) are enzymes responsible for the phosphorylation and activation of downstream effectors in the B-cell receptor (BCR) signaling and T cell receptor (TCR) signaling pathways, respectively. Ibrutinib is an FDA-approved potent inhibitor of both BTK and ITK that impairs B-cell and T-cell function. CD4 T cells and B cells are essential for the induction of chronic graft-versus-host disease (cGVHD). We evaluated these targets by testing the...

Data from: The relationship of recombination rate, genome structure, and patterns of molecular evolution across angiosperms

George Paul Tiley & J. Gordon Burleigh
Background: Although homologous recombination affects the efficacy of selection in populations, the pattern of recombination rate evolution and its effects on genome evolution across plants are largely unknown. Recombination can reduce genome size by enabling the removal of LTR retrotransposons, alter codon usage by GC biased gene conversion, contribute to complex histories of gene duplication and loss through tandem duplication, and enhance purifying selection on genes. Therefore, variation in recombination rate across species may explain...

Data from: Movement is the glue connecting home ranges and habitat selection

Bram Van Moorter, Christer M. Rolandsen, Mathieu Basille & Jean-Michel Gaillard
1. Animal space use has been studied by focusing either on geographic (e.g. home ranges, species' distribution) or on environmental (e.g. habitat use and selection) space. However, all patterns of space use emerge from individual movements, which are the primary means by which animals change their environment. 2. Individuals increase their use of a given area by adjusting two key movement components: the duration of their visit and/or the frequency of revisits. Thus, in spatially...

Data from: The evolutionary history of ferns inferred from 25 low-copy nuclear genes

Carl J. Rothfels, Fay-Wei Li, Erin M. Sigel, Layne Huiet, Anders Larsson, Dylan O. Burge, Markus Ruhsam, Michael Deyholos, Douglas E. Soltis, , Shane W. Shaw, Lisa Pokorny, Tao Chen, Claude DePamphilis, Lisa DeGironimo, Li Chen, Xiaofeng Wei, Xiao Sun, Petra Korall, Dennis W. Stevenson, Sean W. Graham, Gane Ka-Shu Wong, Kathleen M. Pryer, C. Neal Stewart, Gane K-S. Wong … & Claude De Pamphilis
Premise of the study: Understanding fern (monilophyte) phylogeny and its evolutionary timescale is critical for broad investigations of the evolution of land plants, and for providing the point of comparison necessary for studying the evolution of the fern sister group, seed plants. Molecular phylogenetic investigations have revolutionized our understanding of fern phylogeny, however, to date, these studies have relied almost exclusively on plastid data. Methods: Here we take a curated phylogenomics approach to infer the...

Data from: Inferring speciation history in the Andes with reduced-representation sequence data: an example in the bay-backed antpittas (Aves; Grallariidae; Grallaria hypoleuca s. l.)

Benjamin M. Winger, Peter A. Hosner, Gustavo A. Bravo, Andrés M. Cuervo, Natalia Aristizábal, Luis E. Cueto & John M. Bates
In the Andes, humid-forest organisms frequently exhibit pronounced genetic structure and geographic variation in phenotype, often coincident with physical barriers to dispersal. However, phylogenetic relationships of clades have often been difficult to resolve due to short internodes. Consequently, even in taxa with well-defined genetic structure, the temporal and geographic sequences of dispersal and vicariance events that led to this differentiation have remained opaque, hindering efforts to test the association between diversification and earth history and...

Data from: Historical climatic variability and geographical barriers as drivers of community composition in a biodiversity hotspot

Jessica A. Oswald, J. Gordon Burleigh, David W. Steadman, Scott K. Robinson & Andrew W. Kratter
Aim: To evaluate the roles of Quaternary (< 2.6 Ma) climatic stability and geologic barriers (i.e. the Andes Mountains) in shaping the modern community composition and patterns of endemism in Neotropical dry forest bird communities. Location: Marañón Valley and Tumbes, north-western Peru. Methods: We recorded presence and abundance of species in six dry forest bird communities on either side of the Andes Mountains. We used the data to calculate the beta diversity and phylogenetic beta...

Data from: Contact zone dynamics during early stages of speciation in a chorus frog (Pseudacris crucifer)

Kathryn A. Stewart, James D. Austin, Kelly R. Zamudio & Stephen C. Lougheed
Characterizing the genetic and behavioural consequences of contact between previously geographically isolated lineages provides insights into the mechanisms underlying diversification and ultimately speciation. The spring peeper (Pseudacris crucifer) is a widespread Nearctic chorus frog with six divergent mitochondrial DNA (mtDNA) lineages, many of which came into secondary contact during the Holocene. We examined genetics, morphology, advertisement calls and female preference for two lineages that began diverging in allopatry in the Pliocene and now overlap in...

Data from: Synergistic effects of fire and elephants on arboreal animals in an African savannah

Robert M. Pringle, Duncan M. Kimuyu, Ryan L. Sensenig, Todd M. Palmer, Corinna Riginos, Kari E. Veblen & Truman P. Young
1. Disturbance is a crucial determinant of animal abundance, distribution and community structure in many ecosystems, but the ways in which multiple disturbance types interact remain poorly understood. The effects of multiple-disturbance interactions can be additive, subadditive or super-additive (synergistic). Synergistic effects in particular can accelerate ecological change; thus, characterizing such synergies, the conditions under which they arise, and how long they persist has been identified as a major goal of ecology. 2. We factorially...
