Data from: Effects of removing woody cover on long‐term population dynamics of a rare annual plant (Agalinis auriculata): a study comparing remnant prairie and oldfield habitats

Helen M. Alexander, Cathy D. Collins, Aaron W. Reed, W. Dean Kettle, Daniel A. Collis, Lucy D. Christiana & Vaughn B. Salisbury
1. Worldwide, grasslands are becoming shrublands/forests. In North America, eastern red cedar (Juniperus virginiana) often colonizes prairies. Habitat management can focus on woody removal, but we often lack long-term data on whether removal leads to population recovery of herbaceous plants without seeding. 2. We undertook a long-term study (17 years) of numbers of the rare annual plant Agalinis auriculata in a gridwork of 100 m2 plots in adjacent prairie and oldfield sites in Kansas, USA....

Data from: Influence of preexisting preference for color on sampling and tracking behavior in bumble bees

Gyanpriya Maharaj, Patricia Panzica, Marisa Yoder, Aimee S. Dunlap & Patricia Horack
Animals reduce uncertainty in their lifetime by using information to guide decision making. Information available can be inherited from the past or gathered from the present. Therefore, animals must balance inherited biases with new information that may be in conflict with those potential biases. In our study, we set up color pairings such that an arbitrarily chosen focal color, human-orange, would result in an inherent bias in comparison to three other colors tested resulting in...

Data from: Three decades of annual growth, mortality, physical condition, and microsite for ten tropical rainforest tree species

Deborah A. Clark, David B. Clark & Susan G. Letcher
In lowland tropical rainforest, hundreds of tree species typically occur within mesoscale landscapes (50-500 ha). There is no consensus ecological theory that accounts for the coexistence of so many species with similar morphologies and the same fundamental requirements of light, nutrients, water, and physical space. In part this is due to the limited understanding of post-establishment ecology for the vast majority of tropical tree species. Of even more concern is the lack of understanding of...

Data from: Phylotranscriptomic analysis and genome evolution of the Cypripedioideae (Orchidaceae)

Sarah A. Unruh, Michael R. McKain, Yung-I Lee, Tomohisa Yukawa, Melissa K. McCormick, Richard P. Shefferson, Ann Smithson, James H. Leebens-Mack & J. Chris Pires
Premise of Study: The slipper orchids (Cypripedioideae) are a morphologically distinct subfamily of Orchidaceae. They also have some of the largest genomes in the orchids, which may be due to polyploidy or some other mechanism of genome evolution. We generated ten transcriptomes and incorporated existing RNA-seq data to infer a multi-locus nuclear phylogeny of the Cypripedioideae and to determine if a whole genome duplication event (WGD) correlated to the large genome size of this subfamily....

Data from: Diversification by host switching and dispersal shaped the diversity and distribution of avian malaria parasites in Amazonia

Alan Fecchio, Jeffrey Andrew Bell, Michael David Collins, Izeni Pires Farias, Christopher Harry Trisos, Joseph Andrew Tobias, Vasyl Volodymyr Tkach, Jason David Weckstein, Robert Eric Ricklefs & Henrique Batalha-Filho
Understanding how pathogens and parasites diversify through time and space is fundamental to predicting emerging infectious diseases. Here, we use biogeographic, coevolutionary and phylogenetic analyses to describe the origin, diversity, and distribution of avian malaria parasites in the most diverse avifauna on Earth. We first performed phylogenetic analyses using the mitochondrial cytochrome b (cyt b) gene to determine relationships among parasite lineages. Then, we estimated divergence times and reconstructed ancestral areas to uncover how landscape...

Data from: Effects of conditionally expressed phenotypes and environment on amphibian dispersal in nature

Brittany H. Ousterhout & Raymond D. Semlitsch
Individuals vary greatly in the distance they disperse, and in doing so, strongly affect ecological and evolutionary processes. Dispersal, when viewed as a component of phenotype, can be affected independently or jointly by environment. However, among taxa with complex life cycles that occupy different habitats over ontogeny, the effects of environment on dispersal and the interaction between environment and phenotype remains poorly understood. Here, we conducted a field experiment to measure how dispersal distance was...

Data from: Phylogenetic patterns of trait and trait plasticity evolution: Insights from amphibian embryos

Rick Relyea, Patrick R. Stephens, Lisa N. Barrow, Andrew Blaustein, Paul Bradley, Julia Buck, Ann Chang, Brian I Crother, James Collins, Julia Earl, Stephanie S. Gervasi, Jason T. Hoverman, Olliver Hyman, Emily Claire Moriarty Lemmon, Thomas Luhring, Moses Michelsohn, Christopher M. Murray, Steven Price, Raymond Semlitsch, Andy Sih, Aaron Stoler, Nick VandenBroek, Alexa Warwick, Greta Wengert, John Hammond … & Aaron B. Stoler
Environmental variation favors the evolution of phenotypic plasticity. For many species, we understand the costs and benefits of different phenotypes, but we lack a broad understanding of how plastic traits evolve across large clades. Using identical experiments conducted across North America, we examined prey responses to predator cues. We quantified five life history traits and the magnitude of their plasticity for 23 amphibian species/populations (spanning three families and five genera) when exposed to no cues,...

Data from: A biphasic locomotor response to acute unsignaled high temperature exposure in Drosophila.

Daniela Ostrowski, Autoosa Salari, Melissa Zars & Troy Zars
Unsignaled stress can have profound effects on animal behavior. While most investigation of stress-effects on behavior follows chronic exposures, less is understood about acute exposures and potential after-effects. We examined walking activity in Drosophila following acute exposure to high temperature or electric shock. Compared to initial walking activity, flies first increase walking with exposure to high temperatures then have a strong reduction in activity. These effects are related to the intensity of the high temperature...

Data from: Thermal niche evolution across replicated Anolis lizard adaptive radiations

Alex R. Gunderson, D. Luke Mahler & Manuel Leal
Elucidating how ecological and evolutionary mechanisms interact to produce and maintain biodiversity is a fundamental problem in evolutionary ecology. We investigate this issue by focusing on how physiological evolution affects performance and species coexistence along the thermal niche axis in replicated radiations of Anolis lizards, groups best known for resource partitioning based on morphological divergence. We find repeated divergence in thermal physiology within these radiations, and that this divergence significantly affects performance within natural thermal...

Data from: Evolutionary relationships, cospeciation, and host switching in avian malaria parasites

Robert E. Ricklefs, Sylvia M. Fallon & Eldredge Bermingham
We used phylogenetic analyses of cytochrome b sequences of malaria parasites and their avian hosts to assess the coevolutionary relationships between host and parasite lineages. Many lineages of avian malaria parasites have broad host distributions, which tend to obscure cospeciation events. The hosts of a single parasite or of closely related parasites were nonetheless most frequently recovered from members of the same host taxonomic family, more so than expected by chance. However, global assessments of...

Data from: Brassicales phylogeny inferred from 72 plastid genes: a reanalysis of the phylogenetic localization of two paleopolyploid events and origin of novel chemical defenses

Patrick P. Edger, Jocelyn C. Hall, Alex Harkess, Michelle Tang, Jill Coombs, Setareh Mohammadin, M. Eric Schranz, Zhiyong Xiong, James Leebens-Mack, Blake C. Meyers, Kenneth J. Systma, Marcus A. Koch, Ihsan A. Al-Shehbaz, J. Chris Pires & Kenneth J. Sytsma
PREMISE OF THE STUDY - Previous phylogenetic studies employing molecular markers have yielded various insights into the evolutionary history across Brassicales, but many relationships between families remain poorly supported or unresolved. A recent phylotranscriptomic approach utilizing 1155 nuclear markers obtained robust estimates for relationships among 14 of 17 families. Here we report a complete family‐level phylogeny estimated using the plastid genome. METHODS - We conducted phylogenetic analyses on a concatenated data set comprising 44,926 bp...

Data from: Pollination on the dark side: acoustic monitoring reveals impacts of a total solar eclipse on flight behavior and activity schedule of foraging bees

Candace Galen, Zachary Miller, Austin Lynn, Michael Axe, Samuel Holden, Levi Storks, Edward Ramirez, Emilia Asante, David Heise, Susan Kephart, James Kephart, Eddie Ramirez & Jim Kephart
The total solar eclipse of 21 August 2017 traversed ~5000 km from coast to coast of North America. In its 90-min span, sunlight dropped by three orders of magnitude and temperature by 10–15°C. To investigate impacts of these changes on bee (Hymenoptera: Apoidea) pollinators, we monitored their flights acoustically in natural habitats of Pacific Coast, Rocky Mountain, and Midwest regions. Temperature changes during the eclipse had little impact on bee activity. Most of the explained...

Data from: Ecophenotypy, temporal and spatial fidelity, functional morphology, and physiological trade-offs among intertidal bivalves

John W. Huntley, James D. Schiffbauer, Teresa D. Avila & Jesse S. Broce
Ecophenotypic variation in populations is driven by differences in environmental variables. In marine environments, ecophenotypic variation may be caused by differences in hydrodynamic conditions, substrate type, water depth, temperature, salinity, oxygen concentration, and habitat heterogeneity, among others. Instances of ecophenotypic variation in modern and fossil settings are common, but little is known about the influences of time-averaging and spatial-averaging on their preservation. Here we examine the shell morphology of two adjacent populations, both live-collected and...

Data from: Predator-driven natural selection on risk-taking behavior in anole lizards

Oriol Lapiedra, Thomas W. Schoener, Manuel Leal, Jonathan B. Losos & Jason J. Kolbe
Biologists have long debated the role of behavior in evolution, yet understanding of its role as a driver of adaptation is hampered by the scarcity of experimental studies of natural selection on behavior in nature. After showing that individual Anolis sagrei lizards vary consistently in risk-taking behaviors, we experimentally established populations on eight small islands either with or without Leiocephalus carinatus, a major ground predator. We found that selection predictably favors different risk-taking behaviors under...

Data from: Negative effects of vertebrate on invertebrate herbivores mediated by enhanced plant nitrogen content

Yu Zhu, Zhiwei Zhong, Jordi Pagès, Deborah Finke, Deli Wang, Quanhui Ma, Nazim Hassan, Zhu Hui, Ling Wang & Hui Zhu
1. Classic theory holds that the main interaction within the herbivore guild is competition, based on research focused on co-occurring, similarly-sized species that reduce the quantity of shared plant resources. However, plant quality may also be crucial in mediating herbivore interspecific interactions. This is especially true when competition occurs between distantly-related herbivore species, given that small terrestrial herbivores (e.g. insect herbivores) appear to be more sensitive to alterations of plant quality than plant quantity. 2....

Data from: Clonal evolution and genome stability in a 2,500-year-old fungal individual

James B. Anderson, Johann N. Bruhn, Dahlia Kasimer, Hao Wang, Nicolas Rodrigue & Myron L. Smith
Individuals of the basidiomycete fungus Armillaria are well-known for their ability to spread from woody substrate to substrate on the forest floor through the growth of rhizomoprhs. Here we made 248 collections of A. gallica in one locality in Michigan’s Upper Peninsula. To identify individuals, we genotyped collections with molecular markers and somatic compatibility testing. We found several different individuals in proximity to one another, but one genetic individual stood out as exceptionally large, covering...

Data from: Choice in a floral marketplace: the role of complexity in bumble bee decision-making

Matthew W. Austin, Patricia Horack & Aimee S. Dunlap
Animals have evolved in complex, heterogeneous environments. Thus, decision-making behavior is likely affected by a diversity of co-occurring community-level traits. Here, we investigate how three co-occurring traits of floral communities - the number of flower types, reliability that flowers are associated with a reward, and signal complexity of flowers - affect bumble bee (Bombus impatiens) decision-making. We used arrays of artificial flowers in a full factorial experimental design to assess floral selectivity (preference and constancy),...

Data from: Mollusks from the upper Shackleton Limestone (Cambrian Series 2), Central Transantarctic Mountains, East Antarctica

Thomas M. Claybourn, Sarah M. Jacquet, Christian B. Skovsted, Timothy P. Topper, Lars E. Holmer & Glenn A. Brock
An assemblage of Cambrian Series 2, Stages 3–4 conchiferan mollusks from the Shackleton Limestone, Transantarctic Mountains, East Antarctica is formally described and illustrated. The fauna includes one bivalve, one macromollusk and ten micromollusks, including the first description of the species Xinjispira simplex outside North China. The new fauna shows some similarity to previously described micromollusks from lower Cambrian glacial erratics from the Antarctic Peninsula. The fauna, mainly composed of steinkerns, is relatively low diversity, but...

Data from: Scans for signatures of selection in Russian cattle breed genomes reveal new candidate genes for environmental adaptation and acclimation

Andrey A. Yurchenko, Hans D. Daetwyler, Nikolay Yudin, Robert D. Schnabel, Christy J. Vander Jagt, Vladimir Soloshenko, Bulat Lhasaranov, Ruslan Popov, Jeremey F. Taylor & Denis M. Larkin
Domestication and selective breeding has resulted in over 1000 extant cattle breeds. Many of these breeds do not excel in important traits but are adapted to local environments. These adaptations are a valuable source of genetic material for efforts to improve commercial breeds. As a step toward this goal we identified candidate regions to be under selection in genomes of nine Russian native cattle breeds adapted to survive in harsh climates. After comparing our data...
