Data from: Biodiverse cities: the nursery industry, homeowners, and neighborhood differences drive urban tree composition

Meghan Avolio, Diane Pataki, Tara Trammell, Joanna Endter-Wada, Meghan L. Avolio, Diane E. Pataki & Tara L. E. Trammell
In arid and semi-arid regions, where few if any trees are native, city trees are largely human-planted. Societal factors such as resident preferences for tree traits, nursery offerings, and neighborhood characteristics are potentially key drivers of urban tree community composition and diversity, however they remain critically understudied. We investigated patterns of urban tree structure in residential neighborhoods of the Salt Lake Valley, Utah, combining biological variables, such as neighborhood and plant nursery tree species and...

Data from: Genetic constraints on wing pattern variation in Lycaeides butterflies: a case study on mapping complex, multifaceted traits in structured populations

Lauren K. Lucas, Chris C. Nice, Zach Gompert & Zachariah Gompert
Patterns of phenotypic variation within and among species can be shaped and constrained by trait genetic architecture. This is particularly true for complex traits, such as butterfly wing patterns, that consist of multiple elements. Understanding the genetics of complex trait variation across species boundaries is difficult, as it necessitates mapping in structured populations and can involve many loci with small or variable phenotypic effects. Here, we investigate the genetic architecture of complex wing pattern variation...

Data from: Large-effect mutations generate trade-off between predatory and locomotor ability during arms race coevolution with deadly prey

Michael T.J. Hague, Gabriela Toledo, Shana L. Geffeney, Charles T. Hanifin, , , Michael T. J. Hague & Edmund D. Brodie
Adaptive evolution in response to one selective challenge may disrupt other important aspects of performance. Such evolutionary trade-offs are predicted to arise in the process of local adaptation, but it is unclear if these phenotypic compromises result from the antagonistic effects of simple amino acid substitutions. We tested for trade-offs associated with beneficial mutations that confer tetrodotoxin (TTX) resistance in the voltage-gated sodium channel (NaV1.4) in skeletal muscle of the common garter snake (Thamnophis sirtalis)....

Data from: Priority effects within coinfected hosts can drive unexpected population-scale patterns of parasite prevalence

Patrick A. Clay, Michael H. Cortez, Meghan A. Duffy & Volker H. W. Rudolf
Organisms are frequently coinfected by multiple parasite strains and species, and interactions between parasites within hosts are known to influence parasite prevalence and diversity, as well as epidemic timing. Importantly, interactions between coinfecting parasites can be affected by the order in which they infect hosts (i.e. within-host priority effects). In this study, we use a single-host, two-pathogen, SI model with environmental transmission to explore how within-host priority effects scale up to alter host population-scale infection...

Data from: Parental habituation to human disturbance over time reduces fear of humans in coyote offspring

Christopher J. Schell, Julie K. Young, Elizabeth V. Lonsdorf, Rachel M. Santymie, Jill M. Mateo & Rachel M. Santymire
A fundamental tenet of maternal effects assumes that maternal variance over time should have discordant consequences for offspring traits across litters. Yet, seldom are parents observed across multiple reproductive bouts, with few studies considering anthropogenic disturbances as an ecological driver of maternal effects. We observed captive coyote (Canis latrans) pairs over two successive litters to determine whether among-litter differences in behavior (i.e., risk-taking) and hormones (i.e., cortisol and testosterone) corresponded with parental plasticity in habituation....

Data from: Predation shapes the evolutionary traits of cervid weapons

Matthew C. Metz, Douglas J. Emlen, Daniel R. Stahler, Daniel R. MacNulty, Douglas W. Smith & Mark Hebblewhite
Sexually selected weapons evolved to maximize the individual reproductive success of males in many polygynous breeding species. Many weapons are also retained outside of reproductive periods for secondary reasons, but the importance of these secondary functions is poorly understood. Here we leveraged a unique opportunity from the predator–prey system in northern Yellowstone National Park, WY, USA to evaluate whether predation by a widespread, coursing predator (wolves) has influenced a specific weapon trait (antler retention time)...

Data from: Spatial-temporal dynamics of Neotropical velvet ant (Hymenoptera: Mutillidae) communities along a forest-savanna gradient

Júlio M. Alvarenga, Cecília R. Vieira, Leandro B. Godinho, Pedro H. Campelo, James P. Pitts, Guarino R. Colli, Cecília Rodrigues Vieira, James Purser Pitts, Júlio Miguel Alvarenga, Leandro Braga Godinho, Pedro Henrique Campelo & Guarino Rinaldi Colli
Understanding how and why biological communities are organized over space and time is a major challenge and can aid biodiversity conservation in times of global changes. Herein, spatial-temporal variation in the structure of velvet ant communities was examined along a forest-savanna gradient in the Brazilian Cerrado to assess the roles of environmental filters and interspecific interactions upon community assembly. Velvet ants were sampled using 25 arrays of Y-shaped pitfall traps with drift fences for one...

Data from: Convergent adaptation to dangerous prey proceeds through the same first-step mutation in the garter snake Thamnophis sirtalis

Michael Thomas Jonathan Hague, Chris R. Feldman, , , Michael T.J. Hague & Edmund D. Brodie
Convergent phenotypes often result from similar underlying genetics, but recent work suggests convergence may also occur in the historical order of substitutions en route to an adaptive outcome. We characterized convergence in the mutational steps to two independent outcomes of tetrodotoxin (TTX) resistance in separate geographic lineages of the common garter snake (Thamnophis sirtalis) that coevolved with toxic newts. Resistance is largely conferred by amino acid changes in the skeletal muscle sodium channel (NaV1.4) that...

Data from: Wolf in sheep's clothing: model misspecification undermines tests of the neutral theory for life histories

Matthieu Authier, Lise M. Aubry & Emmanuelle Cam
Understanding the processes behind change in reproductive state along life-history trajectories is a salient research program in evolutionary ecology. Two processes, state dependence and heterogeneity, can drive the dynamics of change among states. Both processes can operate simultaneously, begging the difficult question of how to tease them apart in practice. The Neutral Theory for Life Histories (NTLH) holds that the bulk of variations in life-history trajectories is due to state dependence and is hence neutral:...

Data from: Tree circumference dynamics in four forests characterized using automated dendrometer bands

Valentine Herrmann, Sean M. McMahon, Matteo Detto, James A. Lutz, Stuart J. Davies, Chia-Hao Chang-Yang & Kristina J. Anderson-Teixeira
Stem diameter is one of the most commonly measured attributes of trees, forming the foundation of forest censuses and monitoring. Changes in tree stem circumference include both irreversible woody stem growth and reversible circumference changes related to water status, yet these fine-scale dynamics are rarely leveraged to understand forest ecophysiology and typically ignored in plot- or stand-scale estimates of tree growth and forest productivity. Here, we deployed automated dendrometer bands on 12–40 trees at four...

Data from: Predator foraging response to a resurgent dangerous prey

Aimee Tallian, Douglas W. Smith, Daniel R. Stahler, Matthew C. Metz, Rick L. Wallen, Chris Geremia, Joel Ruprecht, C. Travis Wyman & Daniel R. MacNulty
Prey switching occurs when a generalist predator kills disproportionately more of an abundant prey species and correspondingly spares a rarer species. Although this behaviour is a classic stabilizing mechanism in food web models, little is known about its operation in free-living systems which often include dangerous prey species that resist predation. We used long-term (1995–2015) data from a large mammal system in northern Yellowstone National Park, USA, to understand how prey preference of a wild,...

Data from: Dynamics of genomic change during evolutionary rescue in the seed beetle Callosobruchus maculatus

Alexandre Rego, Frank J. Messina & Zachariah Gompert
Rapid adaptation can be necessary to prevent extinction when populations are exposed to extremely marginal or stressful environments. Factors that affect the likelihood of evolutionary rescue from extinction have been identified, but much less is known about the evolutionary dynamics and genomic basis of successful evolutionary rescue, particularly in multicellular organisms. We conducted an evolve-and-resequence experiment to investigate the dynamics of evolutionary rescue at the genetic level in the cowpea seed beetle, Callosobruchus maculatus, when...
