Data from: Population signatures of large-scale, long-term disjunction and small-scale, short-term habitat fragmentation in an Afromontane forest bird

Jan Christian Habel, Luc Lens, Martin Husemann, Ronald K. Mulwa, Luca Borghesio, Franz Gassert, Dennis Rödder & Werner Ulrich
The Eastern Afromontane cloud forests occur as geographically distinct mountain exclaves. The conditions of these forests range from large to small and from fairly intact to strongly degraded. For this study, we sampled individuals of the forest bird species, the Montane White-eye Zosterops poliogaster from 16 sites and four mountain archipelagos. We analysed 12 polymorphic microsatellites and three phenotypic traits, and calculated Species Distribution Models (SDMs) to project past distributions and predict potential future range...

Data from: Genetic divergence along the speciation continuum: the transition from host race to species in Rhagoletis (Diptera: Tephritdae)

Thomas H. Q. Powell, Glen R. Hood, Mason O. Murphy, Jeffrey S. Heilveil, Stewart H. Berlocher, Partrik Nosil, Jeffrey L. Feder & Patrik Nosil
Studies of related populations varying in their degrees of reproductive isolation can provide insights into speciation. Here, the transition from partially isolated host races to more fully separated sibling species is investigated by comparing patterns of genetic differentiation between recently evolved (∼150 generations) apple and ancestral hawthorn-infesting populations of Rhagoletis pomonella to their sister taxon, the undescribed flowering dogwood fly attacking Cornus florida. No fixed or diagnostic private alleles differentiating the three populations were found...

Data from: Does local adaptation to resources explain genetic differentiation among Daphnia populations?

Michael Allen, Ryan Thum & Carla Cáceres
Substantial genetic differentiation is frequently observed among populations of cyclically parthenogenetic zooplankton despite their high dispersal capabilities and potential for gene flow. Local adaptation has been invoked to explain population genetic differentiation despite high dispersal, but several neutral models that account for basic life history features also predict high genetic differentiation. Here, we study genetic differentiation among four populations of Daphnia pulex in east central Illinois. As with other studies of Daphnia, we demonstrate substantial...

Data from: Ecological drift and local exposures drive gastrointestinal bacterial community differences among Galápagos iguana populations

Emily Lankau Wheeler, Pei-Ying Hong & Roderick I. Mackie
Diet strongly influences the intestinal microbial communities through species sorting. Alternatively, these communicates may differ because of chance variation in local microbial exposures or species losses among allopatric host populations (i.e. ecological drift). We investigated how these forces shape enteric communities of Galápagos marine and land iguanas. Geographically proximate populations shared more similar communities within a host ecotype, suggesting a role for ecological drift during host colonization of the islands. Additionally, evidence of taxa sharing...

Data from: Gut microbiome composition and metabolomic profiles of wild western lowland gorillas (Gorilla gorilla gorilla) reflect host ecology

Andres Gomez, Klara Petrzelkova, Carl J. Yeoman, Klara Vlckova, Jakub Mrázek, Ingrid Koppova, Franck Carbonero, Alexander Ulanov, David Modry, Angelique Todd, Manolito Torralba, Karen Nelson, H. Rex Gaskins, Brenda Wilson, Rebecca M. Stumpf, Bryan A. White, Steven R. Leigh & Karen E. Nelson
The metabolic activities of gut microbes significantly influence host physiology; thus, characterizing the forces that modulate this micro-ecosystem is key to understanding mammalian biology and fitness. To investigate the gut microbiome of wild primates and determine how these microbial communities respond to the host's external environment, we characterized faecal bacterial communities and, for the first time, gut metabolomes of four wild lowland gorilla groups in the Dzanga-Sangha Protected Areas, Central African Republic. Results show that...

Data from: Genomic diversity and differentiation of a managed island wild boar population

Laura Iacolina, Massimo Scandura, Daniel J. Goedbloed, Panoraia Alexandri, Richard P. M. A. Crooijmans, Greger Larson, Alan Archibald, Marco Apollonio, Lawrence B. Schook, Martien A. Groenen & Hendrik-Jan Megens
The evolution of island populations in natural systems is driven by local adaptation and genetic drift. However, evolutionary pathways may be altered by humans in several ways. The wild boar (WB) (Sus scrofa) is an iconic game species occurring in several islands, where it has been strongly managed since prehistoric times. We examined genomic diversity at 49 803 single-nucleotide polymorphisms in 99 Sardinian WBs and compared them with 196 wild specimens from mainland Europe and...

Data from: Scale-dependent role of demography and dispersal on the distribution of populations in heterogeneous landscapes

Benjamin T. Martin, Sergiusz Czesny, David H. Wahl & Volker Grimm
Both dispersal and local demographic processes determine a population's distribution among habitats of varying quality, yet most theory, experiments, and field studies have focused on the former. We use a generic model to show how both processes contribute to a population's distribution, and how the relative importance of each mechanism depends on scale. In contrast to studies only considering habitat-dependent dispersal, we show that predictions of ideal free distribution (IFD) theory are relevant even at...

Data from: Habitat, predators, and hosts regulate disease in Daphnia through direct and indirect pathways

Alexander T. Strauss, Marta S. Shocket, David J. Civitello, Jessica L. Hite, Rachel M. Penczykowski, Meghan A. Duffy, Carla E. Cáceres & Spencer R. Hall
Community ecology can link habitat to disease via interactions among habitat, focal hosts, other hosts, their parasites, and predators. However, complicated food web interactions (i.e., trophic interactions among predators, and their impacts on host density and diversity) often obscure the important pathways regulating disease. Here, we disentangle community drivers in a case study of planktonic disease, using a two-step approach. In step one, we tested univariate field patterns linking community interactions to two disease metrics....

Data from: Herbivorous dinosaur jaw disparity and its relationship to extrinsic evolutionary drivers

Jamie A. MacLaren, Philip S. L. Anderson, Paul Barrett & Emily J. Rayfield
Morphological responses of nonmammalian herbivores to external ecological drivers have not been quantified over extended timescales. Herbivorous nonavian dinosaurs are an ideal group to test for such responses, because they dominated terrestrial ecosystems for more than 155 Myr and included the largest herbivores that ever existed. The radiation of dinosaurs was punctuated by several ecologically important events, including extinctions at the Triassic/Jurassic (Tr/J) and Jurassic/Cretaceous (J/K) boundaries, the decline of cycadophytes, and the origin of...

Data from: Evolution of tolerance in an invasive weed after reassociation with its specialist herbivore

Tania Jogesh, Margaret C. Stanley & May R. Berenbaum
The interaction between the European wild parsnip Pastinaca sativa and its coevolved florivore the parsnip webworm Depressaria pastinacella, established in North America for over 150 years, has resulted in evolution of local chemical phenotype matching. The recent invasion of New Zealand by webworms, exposing parsnips there to florivore selection for the first time, provided an opportunity to assess rates of adaptive response in a real-time experiment. We planted reciprocal common gardens in the USA and...

Data from: Intensifying drought eliminates the expected benefits of elevated carbon dioxide for soybean

Sharon B. Gray, Orla Dermody, Stephanie P. Klein, Anna M. Locke, Justin M. McGrath, Rachel E. Paul, David M. Rosenthal, Ursula M. Ruiz-Vera, Matthew H. Siebers, Reid Strellner, Elizabeth A. Ainsworth, Carl J. Bernacchi, Stephen P. Long, Donald R. Ort & Andrew D. B. Leakey
Stimulation of C3 crop yield by rising concentrations of atmospheric carbon dioxide ([CO2]) is widely expected to counteract crop losses that are due to greater drought this century. But these expectations come from sparse field trials that have been biased towards mesic growth conditions. This eight-year study used precipitation manipulation and year-to-year variation in weather conditions at a unique open-air field facility to show that the stimulation of soybean yield by elevated [CO2] diminished to...

Data from: Serum amyloid A protein concentration in blood is influenced by genetic differences in the cheetah (Acinonyx jubatus)

Ashley D. Franklin, Anne Schmidt-Küntzel, Karen A. Terio, Laurie L. Marker & Adrienne E. Crosier
Systemic amyloid A (AA) amyloidosis is a major cause of morbidity and mortality among captive cheetahs. The self-aggregating AA protein responsible for this disease is a byproduct of serum amyloid A (SAA) protein degradation. Transcriptional induction of the SAA1 gene is dependent on both C/EBPβ and NF-κB cis-acting elements within the promoter region. In cheetahs, 2 alleles exist for a single guanine nucleotide deletion in the putative NF-κB binding site. In this study, a novel...

Data from: Effects of 16S rDNA sampling on estimates of the number of endosymbiont lineages in sucking lice

Julie M. Allen, J. Gordon Burleigh, Jessica E. Light & David L. Reed
Phylogenetic trees can reveal the origins of endosymbiotic lineages of bacteria and detect patterns of co-evolution with their hosts. Although taxon sampling can greatly affect phylogenetic and co-evolutionary inference, most hypotheses of endosymbiont relationships are based on few available bacterial sequences. Here we examined how different sampling strategies of Gammaproteobacteria sequences affect estimates of the number of endosymbiont lineages in parasitic sucking lice (Insecta: Phthirapatera: Anoplura). We estimated the number of louse endosymbiont lineages using...

Data from: Development of a genotype-by-sequencing immunogenetic assay as exemplified by screening for variation in red fox with and without endemic rabies exposure

Michael E. Donaldson, Yessica Rico, Karsten Hueffer, Halie M. Rando, Anna V. Kukekova & Christopher J. Kyle
Pathogens are recognized as major drivers of local adaptation in wildlife systems. By determining which gene variants are favored in local interactions among populations with and without disease, spatially explicit adaptive responses to pathogens can be elucidated. Much of our current understanding of host responses to disease comes from a small number of genes associated with an immune response. High-throughput sequencing (HTS) technologies, such as genotype-by-sequencing (GBS), facilitate expanded explorations of genomic variation among populations....

Data from: Day/night upper thermal limits differ within Ectatomma ruidum ant colonies

Annika S. Nelson, Trey Scott, Maciej Barczyk, Terrence P. McGlynn, Arian Avalos, Elizabeth Clifton, Amlan Das, Andreia Figueiredo, Laura L. Figueroa, Mark Janowiecki, Sarah Pahlke, Jignasha D. Rana & Sean O'Donnell
In the tropics, daily temperature fluctuations can pose physiological challenges for ectothermic organisms, and upper thermal limits may affect foraging activity over the course of the day. Variation in upper thermal limits can occur among and within species, and for social insects such as ants, within colonies. Within colonies, upper thermal limits may differ among individuals or change for an individual throughout the day. Daytime foragers of the Neotropical ant Ectatomma ruidum have higher critical...

M. Groenen, Lusheng Huang & Hendrik-Jan Megens
Background: Pigs were domesticated independently in Eastern and Western Eurasia early during the agricultural revolution, and have since been transported and traded across the globe. Here, we present a worldwide survey on 60K genome-wide single nucleotide polymorphism (SNP) data for 2093 pigs, including 1839 domestic pigs representing 122 local and commercial breeds, 215 wild boars, and 39 out-group suids, from Asia, Europe, America, Oceania and Africa. The aim of this study was to infer global...

Data from: Cyclic bouts of extreme bradycardia counteract the highmetabolism of frugivorous bats

M. Teague O'Mara, Martin Wikelski, Christian C. Voigt, Andries Ter Maat, Henry S. Pollock, Gary Burness, Lanna M. Desantis, Dina K. N. Dechmann & Dina KN Dechmann
Active flight requires the ability to efficiently fuel bursts of costly locomotion while maximizing energy conservation during non-flying times. We took a multi-faceted approach to estimate how fruit-eating bats (Uroderma bilobatum) manage a high-energy lifestyle fueled primarily by fig juice. Miniaturized heart rate telemetry shows that they use a novel, cyclic, bradycardic state that reduces daily energetic expenditure by 10% and counteracts heart rates as high as 900 bpm during flight. Uroderma bilobatum support flight...

Data from: Alteration of plant-species assemblages can decrease the transmission potential of malaria mosquitoes

Babak Ebrahimi, Bryan T. Jackson, Julie L. Guseman, Colin M. Przybylowicz, Christopher M. Stone & Woodbridge A. Foster
1. Knowledge of the link between a vector population’s pathogen-transmission potential and its biotic environment can generate more realistic forecasts of disease risk due to environmental change. It also can promote more effective vector control by both conventional and novel means 2. The present study assessed the effect of particular plant-species assemblages differing in nectar production on components of the vectorial capacity of the mosquito Anopheles gambiae s.s., an important vector of African malaria. 3....

Data from: Human movement, cooperation, and the effectiveness of coordinated vector control strategies

Chris M. Stone, Samantha R. Schwab, Dina M. Fonseca & Nina H. Fefferman
Vector-borne disease transmission is often typified by highly focal transmission and influenced by movement of hosts and vectors across different scales. The ecological and environmental conditions (including those created by humans through vector control programmes) that result in metapopulation dynamics remain poorly understood. The development of control strategies that would most effectively limit outbreaks given such dynamics is particularly urgent given the recent epidemics of dengue, chikungunya and Zika viruses. We developed a stochastic, spatial...
