Data from: Mate choice strategies in a spatially-explicit model environment

Giordano B.S. Ferreira, Matthias Scheutz, Sunny K. Boyd & Giordano B. S. Ferreira
Decisions about the choice of a mate can greatly impact both individual fitness and selection processes. We developed a novel agent-based model to investigate two common mate choice rules that may be used by female gray treefrogs (Hyla versicolor). In this model environment, female agents using the minimum-threshold strategy found higher quality mates and traveled shorter distances on average, compared with female agents using the best-of-n strategy. Females using the minimum-threshold strategy, however, incur significant...

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: Limited genetic evidence for host plant-related differentiation in the Western cherry fruit fly Rhagoletis indifferens (Diptera: Tephritidae)

Gilbert Saint Jean, Glen R. Hood, Scott P. Egan, Thomas H.Q. Powell, Hannes Schuler, Meredith M. Doellman, Mary M. Glover, James J. Smith, Wee L. Yee, Robert B. Goughnour, Howard M.A. Thistlewood, Sheri A. Maxwell, Nusha Keyghobadi, Juan Rull, Martin Aluja, Jeffrey L. Feder & Thomas H. Q. Powell
The shift of the fruit fly Rhagoletis pomonella (Walsh) in the mid-1800s from downy hawthorn, Crataegus mollis (Torrey & Asa Gray) Scheele, to introduced domesticated apple, Malus domestica (Borkhausen), in the eastern USA is a model for ecological divergence with gene flow. A similar system may exist in the northwestern USA and British Columbia, Canada, where Rhagoletis indifferens Curran (Diptera: Tephritidae) attacks the native bitter cherry Prunus emarginata (Douglas ex Hooker) Eaton (Rosaceae). Populations of...

Data from: Spatiotemporal incidence of Zika and associated environmental drivers for the 2015-2016 epidemic in Colombia

Amir S. Siraj, I. Rodriguez-Barraquer, Christopher M. Barker, Natalia Tejedor-Garavito, Dennis Harding, Christopher Lorton, Dejan Lukacevic, Gene Oates, Guido Espana, Moritz U. G. Kraemer, Carrie Manore, Michael A. Johansson, Andrew J. Tatem, Robert C. Reiner & T. Alex Perkins
Despite a long history of mosquito-borne virus epidemics in the Americas, the impact of the Zika virus (ZIKV) epidemic of 2015-2016 was unexpected. The need for scientifically informed decision-making is driving research to understand the emergence and spread of ZIKV. To support that research, we assembled a data set of key covariates for modeling ZIKV transmission dynamics in Colombia, where ZIKV transmission was widespread and the government made incidence data publically available. On a weekly...

Data from: A century of genetic variation inferred from a persistent soil-stored seed bank

Jennifer L. Summers, Brittany Bernik, Colin J. Saunders, Jason S. McLachlan & Michael J. Blum
Stratigraphic accretion of dormant propagules in soil can result in natural archives useful for studying ecological and evolutionary responses to environmental change. Few attempts have been made, however, to use soil-stored seed banks as natural archives, in part because of concerns over non-random attrition and mixed stratification. Here we examine the persistent seed bank of Schoenoplectus americanus, a foundational brackish marsh sedge, to determine whether it can serve as a resource for reconstructing historical records...

Data from: The importance of growing up: juvenile environment influences dispersal of individuals and their neighbours

Stacy B. Endriss, Megan L. Vahsen, Ellyn V. Bitume, J. Grey Monroe, Kathryn G. Turner, Andrew P. Norton & Ruth A. Hufbauer
Dispersal is a key ecological process that is strongly influenced by both phenotype and environment. Here, we show that juvenile environment influences dispersal not only by shaping individual phenotypes, but also by changing the phenotypes of neighbouring conspecifics, which influence how individuals disperse. We used a model system (Tribolium castaneum, red flour beetles) to test how the past environment of dispersing individuals and their neighbours influences how they disperse in their current environment. We found...

Data from: Adaptive periodicity in the infectivity of malaria gametocytes to mosquitoes

Petra Schneider, Samuel S.C. Rund, Natasha L. Smith, Kimberley F. Prior, Aidan J. O'Donnell, Sarah E. Reece & Samuel S. C. Rund
Daily rhythms in behaviour, physiology, and molecular processes are expected to enable organisms to appropriately schedule activities according to consequences of the daily rotation of the Earth. For parasites, this includes capitalizing on periodicity in transmission opportunities and for hosts/vectors, this may select for rhythms in immune defence. We examine rhythms in the density and infectivity of transmission forms (gametocytes) of rodent malaria parasites in the host’s blood, parasite development inside mosquito vectors, and potential...

Data from: Climate-mediated hybrid zone movement revealed with genomics, museum collection and simulation modeling

Sean F. Ryan, Jillian M. Deines, J. Mark Scriber, Michael E. Pfrender, Stuart E. Jones, Scott J. Emrich & Jessica J. Hellmann
Climate-mediated changes in hybridization will dramatically alter the genetic diversity, adaptive capacity and evolutionary trajectory of interbreeding species. Our ability to predict the consequences of such changes will be key to future conservation and management decisions. Here we tested through simulations how recent warming (over a 32-year period) is affecting the geographic extent of a climate-mediated developmental threshold implicated in maintaining a butterfly hybrid zone (Papilio glaucus and Papilio canadensis; Lepidoptera: Papilionidae). These simulations predict...

Data from: Standing geographic variation in eclosion time and the genomics of host race formation in Rhagoletis pomonella fruit flies

Meredith M. Doellman, Scott P. Egan, Gregory J. Ragland, Peter J. Meyers, Glen R. Hood, Thomas H.Q. Powell, Peter Lazorchak, Daniel A. Hahn, Stewart H. Berlocher, Patrik Nosil, Jeff L. Feder, Jeffrey L. Feder & Thomas H. Q. Powell
Taxa harboring high levels of standing variation may be more likely to adapt to rapid environmental shifts and experience ecological speciation. Here, we characterize geographic and host-related differentiation for 10,241 single nucleotide polymorphisms in Rhagoletis pomonella fruit flies to infer if standing genetic variation in adult eclosion time in the ancestral hawthorn (Crataegus spp.)-infesting host race, as opposed to new mutations, contributed substantially to its recent shift to earlier fruiting apple (Malus domestica). Allele frequency...

Data from: Genomic differentiation during speciation-with-gene-flow: comparing geographic and host-related variation in divergent life history adaptation in Rhagoletis pomonella

Meredith M. Doellman, Gregory J. Ragland, Glen R. Hood, Peter J. Meyers, Scott P. Egan, Thomas H.Q. Powell, Peter Lazorchak, Mary M. Glover, Cheyenne Tait, Hannes Schuler, Daniel A. Hahn, Stewart H. Berlocher, James J. Smith, Patrik Nosil, Jeffrey L. Feder, Daniel Hahn, Stewart Berlocher, Peter Meyers, Scott Egan, Jeffrey Feder, Glen Hood, Thomas Powell & Gregory Ragland
A major goal of evolutionary biology is to understand how variation within populations gets partitioned into differences between reproductively isolated species. Here, we examine the degree to which diapause life history timing, a critical adaptation promoting population divergence, explains geographic and host-related genetic variation in ancestral hawthorn and recently derived apple-infesting races of Rhagoletis pomonella. Our strategy involved combining experiments on two different aspects of diapause (initial diapause intensity and adult eclosion time) with a...

Data from: Local and system-wide adaptation is influenced by population connectivity

Patrik Nosil, Victor Soria-Carrasco, Jeffery L. Feder, Samuel M. Flaxman, Zachariah Gompert, Jeffrey L. Feder & Zach Gompert
Complex systems can be conceptualized and studied as networks of nodes with varying connectivity between nodes. In well-connected systems, local disturbance of individual nodes can be countered by input from neighbouring nodes, buffering the system against local change. Thus, pronounced change in a well-connected system may not occur until the system hits a threshold or ‘tipping point’ that drives a shift to an alternative, system-wide state. In contrast, poorly connected systems are more prone to...

Data from: Natural selection and the predictability of evolution in Timema stick insects

Patrik Nosil, Romain Villoutreix, Clarissa F. De Carvalho, Tim E. Farkas, Victor Soria-Carrasco, Jeff L. Feder, Bernard J. Crespi & Zachariah Gompert
Predicting evolution remains difficult. We studied the evolution of cryptic body coloration and pattern in a stick insect using 25 years of field data, experiments, and genomics. We found that evolution is more difficult to predict when it involves a balance between multiple selective factors and uncertainty in environmental conditions than when it involves feedback loops that cause consistent back-and-forth fluctuations. Specifically, changes in color-morph frequencies are modestly predictable through time (r2 = 0.14) and...

Data from: Spatio-temporal genetic structure of Anopheles gambiae in the Northwestern Lake Victoria Basin, Uganda: implications for genetic control trials in malaria endemic regions

Martin Lukindu, Christina M. Bergey, Rachel M. Wiltshire, Scott T. Small, Brian P. Bourke, Jonathan K. Kayondo & Nora J. Besansky
Background: Understanding population genetic structure in the malaria vector Anopheles gambiae (s.s.) is crucial to inform genetic control and manage insecticide resistance. Unfortunately, species characteristics such as high nucleotide diversity, large effective population size, recent range expansion, and high dispersal ability complicate the inference of genetic structure across its range in sub-Saharan Africa. The ocean, along with the Great Rift Valley, is one of the few recognized barriers to gene flow in this species, but...

Data from: Effects of sampling effort on biodiversity patterns estimated from environmental DNA metabarcoding surveys

Erin K. Grey, Louis Bernatchez, Phillip Cassey, Kristy Deiner, Marty Deveney, Kimberley L. Howland, Anaïs Lacoursière-Roussel, Sandric Chee Yew Leong, Yiyuan Li, Brett Olds, Michael E. Pfrender, Thomas A. A. Prowse, Mark A. Renshaw & David M. Lodge
Environmental DNA (eDNA) metabarcoding can greatly enhance our understanding of global biodiversity and our ability to detect rare or cryptic species. However, sampling effort must be considered when interpreting results from these surveys. We explored how sampling effort influenced biodiversity patterns and nonindigenous species (NIS) detection in an eDNA metabarcoding survey of four commercial ports. Overall, we captured sequences from 18 metazoan phyla with minimal differences in taxonomic coverage between 18 S and COI primer...
