Raw data for: No reproductive benefits of dear enemy recognition in a territorial songbird

Michael Reichert, Jodie Crane, Gabrielle Davidson, Eileen Dillane, Ipek Kulahci, James O'Neill, Kees Van Oers, Ciara Sexton & John Quinn
Territorial animals often learn to distinguish their neighbors from unfamiliar conspecifics. This cognitive ability facilitates the dear enemy effect, where individuals respond less aggressively to neighbors than to other individuals, and is hypothesized to be adaptive by reducing unnecessary aggressive interactions with individuals that are not a threat to territory ownership. A key prediction of this hypothesis, that individuals with better ability to learn to recognize neighbors should have higher fitness, has never been tested....

What explains vast differences in jumping power within a clade? diversity, ecology, and evolution of anuran jumping power

Elizabeth Mendoza, Manny Azizi & Daniel Moen
1. Anuran (frog and toad) jumping power varies greatly across species, yet muscle power does not. Given that the jumping power of some species is up to five times higher than typical muscle power, power amplification by elastic elements is suggested to explain this discrepancy. However, the ecological reasons for this variation in jumping power are unclear. One hypothesis is that small jumpers are limited by the time available to accelerate their body during take-off,...

The evolution of fossorial locomotion in the transition from tetrapod to snake-like in lizards

& Philip J Bergmann
Dramatic evolutionary transitions in morphology are often assumed to be adaptive in a new habitat. However, these assumptions are rarely tested because such tests require intermediate forms, which are often extinct. In vertebrates, the evolution of an elongate, limbless body is generally hypothesized to facilitate locomotion in fossorial and/or cluttered habitats. However, these hypotheses remain untested because few studies examine the locomotion of species ranging in body form from tetrapod to snake-like. Here, we address...

Becoming creatures of habit: among- and within-individual variation in nesting behavior shifts with age

David Delaney, Luke Hoekstra & Fredric Janzen
The quantification of repeatability has enabled behavioral and evolutionary ecologists to assess the heritable potential of traits. For behavioral traits that vary across life, age-related variation should be accounted for to prevent biasing the microevolutionary estimate of interest. Moreover, to gain a mechanistic understanding of ontogenetic variation in behavior, among- and within-individual variance should be quantified across life. We leveraged a 30-year study of painted turtles (Chrysemys picta) to assess how age contributes to variation...

A time-lagged association between the gut microbiome, nestling weight and nestling survival in wild great tits

Gabrielle Davidson, Shane Somers, Niamh Wiley, Crystal Johnson, Micheal Reichert, R. Paul Ross, Catherine Stanton & John Quinn
Natal body mass is a key predictor of viability and fitness in many animals. While variation in body mass and therefore viability of juveniles may be explained by genetic and environmental factors, emerging evidence points to the gut microbiota as an important factor influencing host health. The gut microbiota is known to change during development, but it remains unclear whether the microbiome predicts fitness, and if it does, at which developmental stage it affects fitness...

Age predicts risky investment better than residual reproductive value

David Delaney, Luke Hoekstra & Fredric Janzen
Life-history theory predicts that investment into reproduction should increase as future reproductive opportunities (i.e., residual reproductive value, RRV) decrease. Researchers have thus intuitively used age as a proxy for RRV and assume RRV decreases with age when interpreting age-specific investment. Yet, age is an imperfect proxy for RRV and may even be a poor correlate in some systems. We used a 30-year study of the nesting ecology of painted turtles ( Chrysemys picta ) to...

Phylogenomic data for hyperdiverse daisy tribes

Jennifer Mandel, Linda Watson & Carolina Siniscalchi
Asteraceae account for 10% of all flowering plant species, and 35-40% of these are in five closely-related tribes that total over 10,000 species. These tribes include Anthemideae, Astereae, Calenduleae, Gnaphalieae, and Senecioneae, which form one of two enormous clades within Subfamily Asteroideae. We took a phylogenomics approach to resolve evolutionary relationships among these five tribes. We sampled the nuclear and plastid genomes via HybSeq target enrichment and genome skimming, and recovered 74 plastid genes and...

Data for: Effects of fire on ground-dwelling arthropods in a shrub-dominated grassland

Shawn Wilder & Anna Butler
Arthropods are abundant and diverse animals in many terrestrial food webs. In western Oklahoma, some shrublands are interspersed with discrete, dense thickets of tall, woody vegetation, known as mottes. Some of these shrublands are managed with prescribed burning. The goal of this study was to examine if prescribed burning interacted with habitat type (i.e., shrubland vs. mottes) to affect ground-dwelling arthropod communities. Arthropods were collected in pitfall traps at four sampling locations in relation to...

QTL × environment interactions underlie adaptive divergence in switchgrass across a large latitudinal gradient

David Lowry, John Lovell, Li Zhang, Jason Bonnette, Philip Fay, Robert Mitchell, John Lloyd-Reilley, Arvid Boe, Yanqi Wu, Francis Rouquette, Richard Wynia, Xiaoyu Weng, Kathrine Behrman, Adam Healey, Kerrie Barry, Anna Lipzen, Diane Bauer, Aditi Sharma, Jerry Jenkins, Jeremy Schmutz, Felix B. Fritschi & Thomas E. Juenger
Local adaptation is the process by which natural selection drives adaptive phenotypic divergence across environmental gradients. Theory suggests that local adaptation results from genetic trade-offs at individual genetic loci, where adaptation to one set of environmental conditions results in a cost to fitness in alternative environments. However, the degree to which there are costs associated with local adaptation is poorly understood because most of these experiments rely on two-site reciprocal transplant experiments. Here, we quantify...

Locomotion and paleoclimate explain the re-evolution of quadrupedal body form in Brachymeles lizards

Philip Bergmann, , Elyse Freitas, Duncan Irschick, Gunter Wagner & Cameron Siler
Evolutionary reversals, including re-evolution of lost structures, are commonly found in phylogenetic studies. However, we lack an understanding of how these reversals happen mechanistically. A snake-like body form has evolved many times in vertebrates, and occasionally, a quadrupedal form has re-evolved, including in Brachymeles lizards. We use body form and locomotion data for species ranging from snake-like to quadrupedal to address how a quadrupedal form could re-evolve. We show that large, quadrupedal species are faster...

Effect of stressors on the carrying capacity of spatially distributed metapopulations

Bo Zhang, Donald DeAngelis, Wei-Ming Ni, Yuanshi Wang, Lu Zhai, Alex Kula, Shuang Xu & David Van Dyken
Stressors such as antibiotics, herbicides and pollutants are becoming increasingly common in the environment. The effects of stressors on populations are typically studied in homogeneous, non-spatial settings. However, most populations in nature are spatially distributed over environmentally heterogeneous landscapes with spatially-restricted dispersal. Little is known about the effects of stressors in these more realistic settings. Here, we combine laboratory experiments with novel mathematical theory to rigorously investigate how a stressor’s physiological effect and spatial distribution...

Structural and compositional heterogeneity influences the thermal environment across multiple scales

David Londe, Dwayne Elmore, Craig Davis, Sam Fuhlendorf, Barney Luttbeg & Torre Hovick
Heterogeneity is becoming increasingly recognized as a critical driver of biodiversity and ecosystem processes. While the influence of heterogeneity on species diversity and abundance is well documented, how heterogeneity influences the distribution and arrangement of important resources across a landscape is still unclear. In particular, the mechanistic relationship between temperature and heterogeneity remains to be explored. Heterogeneity in vegetation structure and composition is often cited as important drivers of the near ground thermal environment. Due...

Phosphorus-supply driven shifts in the quotas of multiple elements in algae and Daphnia: ionomic basis of stoichiometric constraints

Punidan Jeyasingh, Jared Goos, Patrick Lind & Ryan Sherman
The growth rate hypothesis posits that the rate of protein synthesis is constrained by phosphorus (P) supply. P scarcity invokes differential expression of genes involved in processing of most if not all elements encompassing an individual (the ionome). Whether such ionome-wide adjustments to P supply impact growth and trophic interactions is unclear. We quantified the ionomes of a resource-consumer pair in contrasting P supply conditions. Consumer growth penalty was driven by not only P imbalance...

Multiple factors affect discrimination learning performance, but not between-individual variation, in wild mixed-species flocks of birds

Michael Reichert, Sam Crofts, Gabrielle Davidson, Josh Firth, Ipek Kulahci & John Quinn
Cognition arguably drives most behaviours in animals, but whether and why individuals in the wild vary consistently in their cognitive performance is scarcely known, especially under mixed-species scenarios. One reason for this is that quantifying the relative importance of individual, contextual, ecological and social factors remains a major challenge. We examined how many of these factors, and sources of bias, affected participation, and performance, in an initial discrimination learning experiment and two reversal learning experiments...

Quantitative genetics of phosphorus content in the freshwater herbivore, Daphnia pulicaria

Ryan Sherman, Rachel Hartnett, Emily Kiehnau, Lawrence Weider & Punidan Jeyasingh
1. Phosphorus (P) is essential for growth of all organisms, and P content is correlated with growth in most taxa. Although P content was initially considered to be a trait fixed at the species level, there is growing evidence for considerable intraspecific variation. Selection on such variation can thus alter the rates at which P fluxes through food webs. 2. Nevertheless, prior work describing the sources and extent of intraspecific variation in P content were...

Data from: Wintering grounds, population size and evolutionary history of a cryptic passerine species from isotopic and genetic data

Ivan De La Hera, Jordi Gomez, Eileen Dillane, Azaitz Unanue, Anton Perez-Rodriguez, Javier Perez-Tris & Maria Torres-Sanchez
Cryptic species pose a particular challenge to biologists in the context of life history investigations because of the difficulty in their field discrimination. Additionally, there is normally a lag in their widespread acceptance by the scientific community once they are formally recognised. These two factors might constrain our ability to properly assess the conservation status of the different species conforming a cryptic complex. In this study, we analysed isotopic and genetic data to shed light...

Testing for adaptive radiation: a new approach applied to Madagascar frogs

Daniel Moen, Rojo Ravelojaona, Carl Hutter & John Wiens
Adaptive radiation is a key topic at the intersection of ecology and evolutionary biology. Yet the definition and identification of adaptive radiation both remain contentious. Here, we introduce a new approach for identifying adaptive radiations which combines key aspects of two widely used definitions. Our approach compares evolutionary rates in morphology, performance, and diversification between the candidate radiation and other clades. We then apply this approach to a putative adaptive radiation of frogs from Madagascar...

Structural implications of traditional agricultural landscapes on the functional diversity of birds near the Korean Demilitarized Zone

Jae Hyun Kim, Shinyeong Park, Seung Ho Kim, Keunwon Kang, Bruce Waldman, Myung Hwa Lee, Minhye Yu, Hyunyoung Yang, Hyun Yong Chung & Eun Ju Lee
Bird assemblages are sensitive to changes in landscape composition and the environment, such as those that result from drought. In this study, the relationship between landscape composition and avian functional diversity in traditional agricultural ecosystems in the Civilian Control Zone (CCZ) of Korea was examined. In addition, the resilience of biodiversity to changes in landscape elements resulting from drought conditions was investigated. The traditional agricultural landscape (TAL) of the sites studied was divided into three...

Pinyon jay (Gymnorhinus cyanocephalus) nest site selection in central New Mexico: Habitat Data to be used with AICc

Michael Novak, Loren Smith & Scott McMurry
Pinyon Jays (Gymnorhinus cyanocephalus) are experiencing range wide population declines primarily in response to habitat degradation. Studies examining Pinyon Jay nest site selection in pinyon-juniper woodlands would be helpful in determining potential habitat management prescriptions. Therefore, we conducted a nest site selection study in Pinyon Jay breeding habitat in central New Mexico. We compared size and foliage characteristics of pinyon and juniper trees in 42 17.5-m radius plots around Pinyon Jay nests to 41 same-sized...
