Data from: Identification of candidate effector genes of Pratylenchus penetrans

Paulo Vieira, Thomas Mayer, Sebastian Eves-Van Den Akker, Dana K. Howe, Inga Zasada, Thomas Baum, Jonathan D. Eisenback, Kathryn Kamo, Thomas R. Maier & Thomas J. Baum
Pratylenchus penetrans is one of the most important species among root lesion nematodes (RLNs) due to the detrimental and economic impact that it causes in a wide range of crops. Similar to other plant-parasitic nematodes (PPNs), P. penetrans harbors a significant number of secreted proteins that play key roles during parasitism. Here we combined spatially and temporally resolved next generation sequencing datasets of P. penetrans to select a list of candidate genes aimed at the...

Data from: Grazing enhances belowground carbon allocation, microbial biomass, and soil carbon in a subtropical grassland

Chris H. Wilson, Michael S. Strickland, Jack A. Hutchings, Thomas S. Bianchi & S. Luke Flory
Despite the large contribution of rangeland and pasture to global soil organic carbon (SOC) stocks, there is considerable uncertainty about the impact of large herbivore grazing on SOC, especially for understudied subtropical grazing lands. It is well known that root system inputs are the source of most grassland SOC, but the impact of grazing on partitioning of carbon allocation to root tissue production compared to fine root exudation is unclear. Given that different forms of...

Data from: Production of omega-3 enriched tilapia through the dietary use of algae meal or fish oil: Improved nutrient value of fillet and offal

Tyler R. Stoneham, David D. Kuhn, Daniel P. Taylor, Andrew P. Neilson, Stephen A. Smith, Delbert M. Gatlin, Hyun Sik S. Chu, Sean F. O'Keefe & Sean F. O’Keefe
The goal of this project was to increase the nutrient value of fillets, by-product muscle, and offal of aquacultured tilapia. A diet that includes seafood with a high omega-3 (n-3) fatty acid content, more specifically eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA), are known to have numerous health benefits for consumers. Improved nutrient value of the offal may also attract new market opportunities for the aquaculture industry. Tilapia were cultured on different experimental feeds that...

Data from: Why are you swiping right? The impact of product orientation on swiping responses

Anneleen Van Kerckhove & Mario Pandelaere
Many apps require consumers to evaluate products by swiping them, to the right or left. This work explores whether product orientation affects the product evaluations communicated by swiping movements, compared with those made by pressing onscreen buttons. Building on stimulus-response compatibility (SRC) theory, which suggests that irrelevant product display features can activate certain behavioral responses when the product display and the behavioral response share a common dimension, this study predicts that the horizontal direction (left-to-right...

Data from: Ecological correlates of the spatial co-occurrence of sympatric mammalian carnivores worldwide

Courtney L. Davis, Lindsey N. Rich, Zach J. Farris, Marcella J. Kelly, Mario S. Di Bitetti, Yamil Di Blanco, Sebastian Albanesi, Mohammad S. Farhadinia, Navid Gholikhani, Sandra Hamel, Bart J. Harmsen, Claudia Wultsch, Mamadou D. Kane, Quinton Martins, Asia J. Murphy, Robin Steenweg, S. Sunarto, Atieh Taktehrani, Kanchan Thapa, Jody M. Tucker, Jesse Whittington, Febri A. Widodo, Nigel G. Yoccoz & David A.W. Miller
The composition of local mammalian carnivore communities has far-reaching effects on terrestrial ecosystems worldwide. To better understand how carnivore communities are structured, we analyzed camera trap data for 108,087 trap days across 12 countries spanning 5 continents. We estimate local probabilities of co-occurrence among 768 species pairs from the order Carnivora and evaluate how shared ecological traits correlated with probabilities of co-occurrence. Within individual study areas, species pairs co-occurred more frequently than expected at random....

Data from: Using host-associated differentiation to track source population and dispersal distance among insect vectors of plant pathogens

Gina M. Angelella, Andy P. Michel, Ian Kaplan, G.M. Angelella & A.P. Michel
Small, mobile insects are notoriously challenging to track across landscapes and manage in agricultural fields. However, genetic differentiation among insect populations and host-plants acquired through host-associated differentiation could be exploited to infer movement within crop systems and damage potential. Although many insects exhibit host-associated differentiation, management strategies for insect vectors of plant pathogens assume a homogenous population. Nevertheless, phenotypic changes derived from host-associated differentiation could manifest in altered behavior or physiology affecting the likelihood of...

Data from: Contemporaneous radiations of fungi and plants linked to symbiosis

François Lutzoni, Michael D. Nowak, Michael E. Alfaro, Valérie Reeb, Jolanta Miadlikowska, Michael Krug, A. Elizabeth Arnold, Louise A. Lewis, David L. Swofford, David Hibbett, Khidir Hilu, Timothy Y. James, Dietmar Quandt & Susana Magallón
Interactions between fungi and plants, including parasitism, mutualism, and saprotrophy, have been invoked as key to their respective macroevolutionary success. Here we evaluate the origins of plant-fungal symbioses and saprotrophy using a time-calibrated phylogenetic framework that reveals linked and drastic shifts in diversification rates of each kingdom. Fungal colonization of land was associated with at least two origins of terrestrial green algae and preceded embryophytes (as evidenced by losses of fungal flagellum, ca. 720 Ma),...

Data from: Response of bluebunch wheatgrass to invasion: differences in competitive ability among invader-experienced and naïve populations

Alexis L. Gibson, Cara R. Nelson, Daniel Z. Atwater & Alexis Gibson
1. Invasive species may alter selective pressures on native plant populations, and there is some evidence that competition with invasive plants may lead to differences in competitive ability between populations that have experienced invasion and those that have not. Previous results have varied among species but also among populations of the same species. 2. We conducted a greenhouse experiment to determine whether there was variation in traits, or in ability to tolerate or suppress an...

Data from: Estimating transient populations of unmarked individuals at a migratory stopover site using generalized N-mixture models

Eunbi Kwon, Lawrence M. Houghton, Robert E. Settlage, Daniel H. Catlin, Sarah M. Karpanty & James D. Fraser
1. Migration counts are popular indices used to monitor population trends over time. Advanced analytical methods for estimating abundance of unmarked, open populations now incorporate population growth models and simultaneously test for covariate effects on abundance and detection probability. However, estimating population abundance at a staging site is complicated by daily immigration and emigration of unmarked individuals. 2. We applied a set of generalized N-mixture models to simulated count data to test their applicability for...

Data from: Quantifying climate sensitivity and climate-driven change in North American amphibian communities

David A. W. Miller, Evan H. Campbell Grant, Erin Muths, Staci M. Amburgey, Michael J. Adams, Maxwell B. Joseph, J. Hardin Waddle, Pieter T. J. Johnson, Maureen E. Ryan, Benedikt R. Schmidt, Daniel L. Calhoun, Courtney L. Davis, Robert N. Fisher, David M. Green, Blake R. Hossack, Tracy A. G. Rittenhouse, Susan C. Walls, Larissa L. Bailey, Sam S. Cruickshank, Gary M. Fellers, Thomas A. Gorman, Carola A. Haas, Ward Hughson, David S. Pilliod, Steven J. Price … & Brent H. Sigafus
Changing climate will impact species’ ranges only when environmental variability directly impacts the demography of local populations. However, measurement of demographic responses to climate change has largely been limited to single species and locations. Here we show that amphibian communities are responsive to climatic variability, using >500,000 time-series observations for 81 species across 86 North American study areas. The effect of climate on local colonization and persistence probabilities varies among eco-regions and depends on local...

Data from: Step-wise evolution of complex chemical defenses in millipedes: a phylogenomic approach

Juanita Rodriguez, Tappey H. Jones, Petra Sierwald, Paul E. Marek, William A. Shear, Michael S. Brewer, Kevin M. Kocot & Jason E. Bond
With fossil representatives from the Silurian capable of respiring atmospheric oxygen, millipedes are among the oldest terrestrial animals, and likely the first to acquire diverse and complex chemical defenses against predators. Exploring the origin of complex adaptive traits is critical for understanding the evolution of Earth’s biological complexity, and chemical defense evolution serves as an ideal study system. The classic explanation for the evolution of complexity is by gradual increase from simple to complex, passing...

Data from: Response of Prochilodus nigricans to flood pulse variation in the central Amazon

Peter B. Bayley, Leandro Castello, Vandick S. Batista & Nidia N. Fabré
The influence of the flood pulse on fish populations has been posited, but infrequently tested or quantified. Here, we tested the effect of habitat on population size, using Prochilodus nigricans as a case study species. Floodplain habitat was based on the littoral zone area occupied by P. nigricans to feed. The magnitude of this habitat in each hydrological year, the moving littoral (ML), was expressed as the sum of daily littoral areas during the advancing...

Data from: The Bogert effect revisited: salamander regulatory behaviors are differently constrained by time and space

Vincent R. Farallo, Rebecca Wier & Donald B. Miles
The use of behavior to buffer extreme environmental variation is expected to enable species to a) extend the breadth of environments they inhabit beyond that predicted from climatic data, and b) diminish the negative effects of broad-scale and chronic disturbances such as climate change. The term Bogert effect refers to behavioral compensation entailing microhabitat selection to maintain performance across a gradient of environmental conditions resulting in evolutionary inertia of physiological traits. Here we compare microhabitats...

Data from: Rethinking phylogenetic comparative methods

Josef C. Uyeda, Rosana Zenil-Ferguson & Matthew W. Pennell
As a result of the process of descent with modification, closely related species tend to be similar to one another in a myriad different ways. In statistical terms, this means that traits measured on one species will not be independent of traits measured on others. Since their introduction in the 1980s, phylogenetic comparative methods (PCMs) have been framed as a solution to this problem. In this paper, we argue that this way of thinking about...

Data from: Incubation temperature and social context affect the nest exodus of precocial ducklings

Sydney F. Hope, Robert A. Kennamer, Schuyler G. Van Montfrans & William A. Hopkins
The environments that animals experience during development have important fitness consequences. In birds, parents influence the developmental environment of their offspring through incubation. Subtle changes in incubation temperature affect offspring morphology and physiology, such as growth, immune function, and thermoregulation, yet little is known about how it may affect critical early-life behaviors. Because expression of behavior can be influenced by the social environment, the effect of incubation temperature on behavior may be context-dependent. We investigated...

Data from: Adaptive radiation along a deeply conserved genetic line of least resistance in Anolis lizards

Joel W. McGlothlin, Megan E. Kobiela, Helen V. Wright, D. Luke Mahler, Jason J. Kolbe, Jonathan B. Losos, & Edmund D. Brodie
On microevolutionary timescales, adaptive evolution depends upon both natural selection and the underlying genetic architecture of traits under selection, which may constrain evolutionary outcomes. Whether such genetic constraints shape phenotypic diversity over macroevolutionary timescales is more controversial, however. One key prediction is that genetic constraints should bias the early stages of species divergence along “genetic lines of least resistance” defined by the genetic (co)variance matrix, G. This bias is expected to erode over time as...

Data from: The evolution of the dicynodont sacrum: constraint and innovation in the synapsid axial column

Christopher T. Griffin & Kenneth D. Angielczyk
Constraint is a universal feature of morphological evolution. The vertebral column of synapsids (mammals and their close relatives) is a classic example of this phenotypic restriction, with greatly reduced variation in the number of vertebrae compared to the sauropsid lineage. Synapsids generally possess only three sacral vertebrae, which articulate with the ilium and play a key role in locomotion. Dicynodont anomodonts are the exception to this rule, possessing seven or more sacral vertebrae while reaching...

Data from: Parameterizing the robust design in the BUGS language: lifetime carry‐over effects of environmental conditions during growth on a long‐lived bird

Thomas V. Riecke, Alan G. Leach, Dan Gibson & James S. Sedinger
1. Since the initial development of the robust design, this capture‐recapture model structure has been modified to estimate temporary emigration, and expanded to include auxiliary information such as band recovery and live resight data using maximum likelihood approaches. These developments have allowed investigators to separately assess individual and group effects on true survival, site fidelity, and temporary emigration. Additionally, recent advances in the BUGS language have allowed researchers to develop increasingly complex, user‐specified models in...

Data from: Free‐moving artificial eggs containing temperature loggers reveal remarkable within‐clutch variance in incubation temperature

Sydney F. Hope, Sarah E. DuRant, John J. Hallagan, Michelle L. Beck, Robert A. Kennamer & William A. Hopkins
Incubation is a crucial aspect of avian parental care and measuring incubation temperature in the wild can improve our understanding of life history tradeoffs and inform conservation efforts. However, there are challenges associated with measuring the temperature of eggs in natural nests. Most studies to date have measured incubation temperature by using a single, stationary logger in each nest. However, real eggs are rotated and moved throughout the nest by the parent during the incubation...

Data from: Crop pests and predators exhibit inconsistent responses to surrounding landscape composition

Daniel S. Karp, Rebecca Chaplin-Kramer, Timothy D. Meehan, Emily A. Martin, Fabrice DeClerck, Heather Grab, Claudio Gratton, Lauren Hunt, Ashley E. Larsen, Alejandra Martínez-Salinas, Megan E. O’Rourke, Adrien Rusch, Katja Poveda, Mattias Jonsson, Jay A. Rosenheim, Nancy A. Schellhorn, Teja Tscharntke, Stephen D. Wratten, Wei Zhang, Aaron L. Iverson, Lynn S. Adler, Matthias Albrecht, Audrey Alignier, Gina M. Angelella, Muhammad Zubair Anjum … & Yi Zou
The idea that noncrop habitat enhances pest control and represents a win–win opportunity to conserve biodiversity and bolster yields has emerged as an agroecological paradigm. However, while noncrop habitat in landscapes surrounding farms sometimes benefits pest predators, natural enemy responses remain heterogeneous across studies and effects on pests are inconclusive. The observed heterogeneity in species responses to noncrop habitat may be biological in origin or could result from variation in how habitat and biocontrol are...

Data from: An evaluation of transferability of ecological niche models

Huijie Qiao, Xiao Feng, Luis E. Escobar, A. Townsend Peterson, Jorge Soberon, Gengping Zhu & Monica Papeș
Ecological niche modeling (ENM) is used widely to study species’ geographic distributions. ENM applications frequently involve transferring models calibrated with environmental data from one region to other regions or times that may include novel environmental conditions. When novel conditions are present, transferability implies extrapolation, whereas, in absence of such conditions, transferability is an interpolation step only. We evaluated transferability of models produced using 11 ENM algorithms from the perspective of interpolation and extrapolation in a...

Data from: Incomplete host immunity favors the evolution of virulence in an emergent pathogen

Arietta E. Fleming-Davies, Paul D. Williams, André A. Dhondt, Andrew P. Dobson, Wesley A. Hochachka, Ariel E. Leon, David H. Ley, Erik E. Osnas & Dana M. Hawley
Immune memory evolved to protect hosts from reinfection, but incomplete responses that allow future reinfection might inadvertently select for more harmful pathogens. We present empirical and modeling evidence that incomplete immunity promotes the evolution of higher virulence in a natural host-pathogen system. We performed sequential infections of house finches with Mycoplasma gallisepticum strains of varying virulence. Virulent bacterial strains generated stronger host protection against reinfection than less virulent strains, and thus excluded less virulent strains...
