Data from: Interbirth intervals in wild baboons: environmental predictors and hormonal correlates

Laurence R. Gesquiere, Jeanne Altmann, Elizabeth A. Archie & Susan C. Alberts
Objectives: Interbirth intervals (IBIs) are a key metric of female reproductive success; understanding how they are regulated by environmental, social, and demographic factors can provide insight into sources of variance in female fitness. Materials and Methods: Using 36 years of reproductive data on 490 IBIs for 160 wild female baboons, we identified sources of variance in the duration of IBIs and of their component phases: postpartum amenorrhea (PPA), sexual cycling, and pregnancy. We also examined...

Data from: Genome-wide analysis of SNPs is consistent with no domestic dog ancestry in the endangered Mexican wolf (Canis lupus baileyi)

Robert R. Fitak, Sarah E. Rinkevich & Melanie Culver
The Mexican gray wolf (Canis lupus baileyi) was historically distributed throughout the southwestern United States and northern Mexico. Extensive predator removal campaigns during the early 20th century, however, resulted in its eventual extirpation by the mid 1980s. At this time, the Mexican wolf existed only in three separate captive lineages (McBride, Ghost Ranch, and Aragón) descended from three, two, and two founders, respectively. These lineages were merged in 1995 to increase the available genetic variation,...

Data from: Urbanization and anticoagulant poisons promote immune dysfunction in bobcats

Laurel E.K. Serieys, Amanda J. Lea, Marta Epeldegui, Tiffany C. Armenta, Joanne Moriarty, Sue Vandewoude, Scott Carver, Janet Foley, Robert K. Wayne, Seth P.D. Riley, Christel H. Uittenbogaart, Laurel E. K. Serieys & Seth P. D. Riley
Understanding how human activities influence immune response to environmental stressors can support biodiversity conservation across increasingly urbanizing landscapes. We studied a bobcat (Lynx rufus) population in urban southern California that experienced a rapid population decline from 2002–2005 due to notoedric mange. Because anticoagulant rodenticide (AR) exposure was an underlying complication in mange deaths, we aimed to understand sublethal contributions of urbanization and ARs on 65 biochemical markers of immune and organ function. Variance in immunological...

Data from: Moving in the Anthropocene: global reductions in terrestrial mammalian movements

Marlee A. Tucker, Katrin Böhning-Gaese, William F. Fagan, John M. Fryxell, Bram Van Moorter, Susan C. Alberts, Abdullahi H. Ali, Andrew M. Allen, Nina Attias, Tal Avgar, Hattie Bartlam-Brooks, Buuveibaatar Bayarbaatar, Jerrold L. Belant, Alessandra Bertassoni, Dean Beyer, Laura Bidner, Floris M. Van Beest, Stephen Blake, Niels Blaum, Chloe Bracis, Danielle Brown, P. J. Nico De Bruyn, Francesca Cagnacci, Justin M. Calabrese, Constança Camilo-Alves … & Thomas Mueller
Animal movement is fundamental for ecosystem functioning and species survival, yet the effects of the anthropogenic footprint on animal movements have not been estimated across species. Using a unique GPS-tracking database of 803 individuals across 57 species, we found that movements of mammals in areas with a comparatively high human footprint were on average one-half to one-third the extent of their movements in areas with a low human footprint. We attribute this reduction to behavioral...

Data from: Using phylogenomic data to explore the effects of relaxed clocks and calibration strategies on divergence time estimation: primates as a test case

Mario Dos Reis, Gregg F. Gunnell, Jose Barba-Montoya, Alex Wilkins, Ziheng Yang & Anne D. Yoder
Primates have long been a test case for the development of phylogenetic methods for divergence time estimation. Despite a large number of studies, however, the timing of origination of crown Primates relative to the K-Pg boundary and the timing of diversification of the main crown groups remain controversial. Here we analysed a dataset of 372 taxa (367 Primates and 5 outgroups, 3.4 million aligned base pairs) that includes nine primate genomes. We systematically explore the...

Data from: Herbivory enhances the resistance of mangrove forest to cordgrass invasion

Yihui Zhang, Hanyu Meng, Yi Wang & Qiang He
The biotic resistance hypothesis proposes that biotic interactions, such as competition and herbivory, resist the establishment and spread of non-native species. The relative and interactive role of competition and herbivory in resisting plant invasions, however, remains poorly understood. We investigated the interactive role of competition and herbivory (by the native rodent Rattus losea) in resisting Spartina alterniflora (cordgrass) invasions into mangrove forests. In southern China, although exotic cordgrass numerically dominates intertidal mudflats and open gaps...

Data from: SNP-skimming: a fast approach to map loci generating quantitative variation in natural populations

Carrie A. Wessinger, John K. Kelly, Peng Jiang, Mark D. Rausher, Lena C. Hileman & Carolyn A. Wessinger
Genome-wide association mapping (GWAS) is a method to estimate the contribution of segregating genetic loci to trait variation. A major challenge for applying GWAS to non-model species has been generating dense genome-wide markers that satisfy the key requirement that marker data is error-free. Here we present an approach to map loci within natural populations using inexpensive shallow genome sequencing. This 'SNP skimming' approach involves two steps: an initial genome-wide scan to identify putative targets followed...

Data from: Speciation in sympatry with ongoing secondary gene flow and an olfactory trigger in a radiation of Cameroon cichlids

Jelmer W. Poelstra, Emilie J. Richards & Christopher H. Martin
The process of sympatric speciation in nature remains a fundamental unsolved problem. Cameroon crater lake cichlid radiations were long regarded as one of the most compelling examples; however, recent work showed that their origins were more complex than a single colonization event followed by isolation. Here, we performed a detailed investigation of the speciation history of a radiation of Coptodon cichlids from Lake Ejagham using whole-genome sequencing data. The existence of this radiation is remarkable...

Data from: Computational biomechanical analyses demonstrate similar shell-crushing abilities in modern and ancient arthropods

Russell D. C. Bicknell, Justin A. Ledogar, Stephen Wroe, Benjamin C. Gutzler, Winsor H. Watson, John R. Paterson & Winsor H. Watson
The biology of the extant American horseshoe crab, Limulus polyphemus, is well documented—including its dietary habits, particularly the ability to crush shell with its gnathobasic walking appendages—but virtually nothing is known about the feeding biomechanics of this iconic arthropod. This species is also considered the archetypal functional analogue for a range of extinct groups that have gnathobasic appendages, including eurypterids, trilobites, and some of the earliest arthropods, especially Sidneyia inexpectans from the middle Cambrian (508...

Data from: Costs of injury for scent signalling in a strepsirrhine primate

Rachel L. Harris, Marylène Boulet, Kathleen E. Grogan & Christine M. Drea
Honesty is crucial in animal communication when signallers are conveying information about their condition. Condition dependence implies a cost to signal production; yet, evidence of such cost is scarce. We examined the effects of naturally occurring injury on the quality and salience of olfactory signals in ring-tailed lemurs (Lemur catta). Over a decade, we collected genital secretions from 23 (13 male, 10 female) adults across 34 unique injuries, owing primarily to intra-group fights. Using gas...

Data from: Costs and benefits of non-random seed release for long distance dispersal in wind-dispersed plant species

Jelle Treep, Monique De Jager, Leandra S. Kuiper, Tomer Duman, Gabriel G. Katul & Merel B. Soons
The dispersal ability of plants is a major factor driving ecological responses to global change. In wind-dispersed plant species, non-random seed release in relation to wind speeds has been identified as a major determinant of dispersal distances. However, little information is available about the costs and benefits of non-random abscission and the consequences of timing for dispersal distances. We asked: 1) To what extent is non-random abscission able to promote long-distance dispersal and what is...

Data from: Development and usability testing of an audit and feedback tool for anesthesiologists

Atilio Barbeito & Noa Segall
Background: We describe the creation and evaluation of a personal audit & feedback (A&F) tool for anesthesiologists. Methods: A survey aimed at capturing barriers for personal improvement efforts and feedback preferences was administered to attending anesthesiologists. The results informed the design and implementation of 4 dashboards that display information on individual practice characteristics as well as comparative performance on several quality metrics. The dashboards’ usability was then tested using the human-centered design framework. Results: Anesthesiologists...

Data from: The diversity of population responses to environmental change

Fernando Colchero, Owen R. Jones, Dalia A. Conde, Dave Hodgson, Felix Zajitschek, Benedikt R. Schmidt, Aurelio F. Malo, Susan C. Alberts, Peter H. Becker, Sandra Bouwhuis, Anne M. Bronikowski, Kristel M. De Vleeschouwer, Richard J. Delahay, Stefan Dummermuth, Eduardo Fernández-Duque, John Frisenvænge, Martin Hesselsøe, Sam Larson, Jean-Francois Lemaitre, Jennifer McDonald, David A.W. Miller, Colin O'Donnell, Craig Packer, Becky E. Raboy, Christopher J. Reading … & Chris J. Reading
The current extinction and climate change crises pressure us to predict population dynamics with ever-greater accuracy. Although predictions rest on the well-advanced theory of age-structured populations, two key issues remain poorly-explored. Specifically, how the age-dependency in demographic rates and the year-to-year interactions between survival and fecundity affect stochastic population growth rates. We use inference, simulations, and mathematical derivations to explore how environmental perturbations determine population growth rates for populations with different age-specific demographic rates and...

Data from: Gene flow, divergent selection and resistance to introgression in two species of morning glories (Ipomoea)

Joanna L. Rifkin, Allan S. Castillo, Irene T. Liao & Mark D. Rausher
Gene flow is thought to impede genetic divergence and speciation by homogenizing genomes. Recent theory and research suggests that strong enough divergent selection can overpower gene flow, leading to islands of divergence. However, there are alternative explanations for these patterns. Independent evidence that islands of divergence are due to divergent selection would allow these explanations to be distinguished, but such evidence is scarce. Here we present multiple lines of evidence that islands of divergence in...

Data from: Seed traits, not density or distance from parent, determine seed predation and establishment in an Afrotropical forest

Cooper Rosin & John R. Poulsen
Seed predators drive patterns in seed mortality and seedling establishment and are posited to contribute to the maintenance of plant species diversity through several mechanisms. Negative density dependence and spatially-restricted recruitment are apparently widespread in Neotropical forests, but are little studied in Afrotropical forests, where generalist vertebrates may contribute more to seed mortality than do specialized invertebrates and fungi. We experimentally assessed the roles of seed density and distance from the parent tree for ten...

Data from: Don’t throw out the sympatric speciation with the crater lake water: fine-scale investigation of introgression provides equivocal support for causal role of secondary gene flow in one of the clearest examples of sympatric speciation

Emilie J. Richards, Jelmer W. Poelstra & Christopher H. Martin
Genomic data has revealed complex histories of colonization and repeated gene flow previously unrecognized in some of the most celebrated examples of sympatric speciation and radiation. However, much of the evidence for secondary gene flow into these radiations comes from summary statistics calculated from sparse genomic sampling without knowledge of which specific genomic regions introgressed. This tells us little about how gene flow potentially influenced sympatric diversification. Here we investigated whole genomes of Barombi Mbo...

Data from: Exposure to predators does not lead to the evolution of larger brains in experimental populations of threespine stickleback

Kieran Samuk, Jan Xue, Diana Jessie Rennison & Diana J. Rennision
Natural selection is often invoked to explain differences in brain size among vertebrates. However, the particular agents of selection that shape brain size variation remain obscure. Recent studies suggest that predators may select for larger brains because increased cognitive and sensory abilities allow prey to better elude predators. Yet, there is little direct evidence that exposure to predators causes the evolution of larger brains in prey species. We experimentally tested this prediction by exposing families...

Data from: Assessing cetacean surveys throughout the Mediterranean Sea: a gap analysis in environmental space

Laura Mannocci, Jason J. Roberts, Patrick N. Halpin, Matthieu Authier, Olivier Boisseau, Mohamed Nejmeddine Bradai, Ana Cañadas, Carla Chicote, Léa David, Nathalie Di-Méglio, Caterina M. Fortuna, Alexandros Frantzis, Manel Gazo, Tilen Genov, Philip S. Hammond, Drasko Holcer, Kristin Kaschner, Dani Kerem, Giancarlo Lauriano, Tim Lewis, Giuseppe Notarbartolo Di Sciara, Simone Panigada, Juan Antonio Raga, Aviad Scheinin, Vincent Ridoux … & Joseph Vella
Heterogeneous data collection in the marine environment has led to large gaps in our knowledge of marine species distributions. To fill these gaps, models calibrated on existing data may be used to predict species distributions in unsampled areas, given that available data are sufficiently representative. Our objective was to evaluate the feasibility of mapping cetacean densities across the entire Mediterranean Sea using models calibrated on available survey data and various environmental covariates. We aggregated 302,481...

Data from: The role of diversification in the continental scale community assembly of the American oaks (Quercus)

Jeannine Cavender-Bares, Shan Kothari, José Eduardo Meireles, Matthew A. Kaproth, Paul S. Manos & Andrew L. Hipp
Premise of the study: Evolutionary and biogeographic history, including past environmental change and diversification processes, are likely to have influenced the expansion, migration, and extinction of populations, creating evolutionary legacy effects that influence regional species pools and the composition of communities. We consider the consequences of the diversification process in shaping trait evolution and assembly of oak-dominated communities throughout the continental U.S. Methods: Within the US oaks, we tested for phylogenetic and functional trait patterns...

Data from: Genomic signatures of population bottleneck and recovery in Northwest Atlantic pinnipeds

Kristina M. Cammen, Thomas F. Schultz, W. Don Bowen, Michael O. Hammill, Wendy B. Puryear, Jonathan Runstadler, Frederick W. Wenzel, Stephanie A. Wood & Michael Kinnison
Population increases over the past several decades provide natural settings in which to study the evolutionary processes that occur during bottleneck, growth, and spatial expansion. We used parallel natural experiments of historical decline and subsequent recovery in two sympatric pinniped species in the Northwest Atlantic, the gray seal (Halichoerus grypus atlantica) and harbor seal (Phoca vitulina vitulina), to study the impact of recent demographic change in genomic diversity. Using restriction site‐associated DNA sequencing, we assessed...

Data from: Near absence of differential gene expression in the retina of rainbow trout after exposure to a magnetic pulse: implications for magnetoreception

Robert R. Fitak, Lorian E. Schweikert, Benjamin R. Wheeler, David A. Ernst, Kenneth J. Lohmann & Sonke Johnsen
The ability to perceive Earth’s magnetic field, or magnetoreception, exists in numerous animals. Although the mechanism underlying magnetoreception has not been clearly established in any species, in salmonid fish it is hypothesized to occur by means of crystals of magnetite associated with nervous tissue such as the brain, olfactory organ, or retina. In this study, rainbow trout (Oncorhynchus mykiss) were exposed to a brief magnetic pulse known to disrupt magnetic orientation behavior in several animals....

Data from: A test of the eavesdropping avoidance hypothesis as an explanation for the structure of low amplitude aggressive signals in the song sparrow

Joseph M. Niederhauser, Adrienne L. DuBois, William A. Searcy, Stephen Nowicki & Rindy C. Anderson
Low amplitude signals function in private exchanges of information between signalers and nearby receivers. The eavesdropping avoidance hypothesis proposes that selection favors quiet threat signals in order to avoid the costs of eavesdroppers. If true, then selection should favor other acoustic traits in addition to low amplitude that lead to quiet signals transmitting less effectively through the environment compared to broadcast signals. The “warbled” soft songs of male song sparrows differ from “crystallized” soft songs...

Data from: Mutual visual signalling between the cleaner shrimp Ancylomenes pedersoni and its client fish

Eleanor M. Caves, Patrick A. Green & Sonke Johnsen
Cleaner shrimp and their reef fish clients are an interspecific mutualistic interaction that is thought to be mediated by signals, and a useful system for studying the dynamics of interspecific signalling. To demonstrate signalling, one must show that purported signals at minimum (a) result in a consistent state change in the receiver and (b) contain reliable information about the sender’s intrinsic state or future behaviour. Additionally, signals must be perceptible by receivers. Here, we document...

Data from: CHIIMP: an automated high-throughput microsatellite genotyping approach reveals greater allelic diversity in wild chimpanzees

Hannah J. Barbian, Andrew Jesse Connell, Alexa N. Avitto, Ronnie M. Russell, Andrew G. Smith, Madhurima S. Gundlapally, Alexander L. Shazad, Yingying Li, Frederic Bibollet-Ruche, Emily E. Wroblewski, Deus Mjungu, Elizabeth V. Lonsdorf, Fiona A. Stewart, Alexander K. Piel, Anne E. Pusey, Paul M. Sharp & Beatrice H. Hahn
Short tandem repeats (STRs), also known as microsatellites, are commonly used to non-invasively genotype wild-living endangered species, including African apes. Until recently, capillary electrophoresis has been the method of choice to determine the length of polymorphic STR loci. However, this technique is labor intensive, difficult to compare across platforms, and notoriously imprecise. Here we developed a MiSeq-based approach and tested its performance using previously genotyped fecal samples from long-term studied chimpanzees in Gombe National Park,...
