Data from: The scale-of-choice effect and how estimates of assortative mating in the wild can be biased due to heterogeneous samples

Emilio Rolan-Alvarez, Antonio Carvajal-Rodriguez, Alicia De Coo, Beatriz Cortés, Daniel Estévez-Barcia, Mar Ferreira, Rubén González & Adriana D. Briscoe
The mode in which sexual organisms choose mates is a key evolutionary process, as it can have a profound impact on fitness and speciation. One way to study mate choice in the wild is by measuring trait correlation between mates. Positive assortative mating is inferred when individuals of a mating pair display traits that are more similar than those expected under random mating while negative assortative mating is the opposite. A recent review of 1134...

Establishment and management of native functional groups in restoration

Sarah Kimball, Megan E. Lulow & Quinn M. Sorenson
The limiting similarity hypothesis predicts that communities should be more resistant to invasion by non-natives when they include natives with a diversity of traits from more than one functional group. In restoration, planting natives with a diversity of traits may result in competition between natives of different functional groups and may influence the efficacy of different seeding and maintenance methods, potentially impacting native establishment. We compare initial establishment and first-year performance of natives and the...

Data from: Transcriptome-wide differential gene expression in Bicyclus anynana butterflies: female vision-related genes are more plastic

Aide Macias-Muñoz, Gilbert Smith, Antónia Monteiro & Adriana D. Briscoe
cave-adapted species down-regulate the expression of vision genes or even lose their eyes and associated eye genes entirely. Alternatively, organisms that live in fluctuating environments, with different requirements for vision at different times, may evolve phenotypic plasticity for expression of vision genes. Here we use a global transcriptomic and candidate gene approach to compare gene expression in the heads of a polyphenic butterfly. Bicyclus anynana have two seasonal forms that display sexual dimorphism and plasticity...

Data from: Effects of climate on reproductive investment in a masting species: assessment of climatic predictors and underlying mechanisms

Xoaquín Moreira, Luis Abdala-Roberts, Yan B. Linhart & Kailen A. Mooney
1. Mechanisms by which climatic factors drive reproductive investment and phenology in masting species are not completely understood. Climatic conditions may act as a proximate cue, stimulating the onset of reproduction and indirectly increasing fitness through benefits associated with synchronous reproduction among individuals. Alternatively, climatic conditions may directly influence individual level allocation to reproduction and reproductive success through effects occurring independently of synchronous reproduction. We previously showed that masting in a ponderosa pine (Pinus ponderosa)...

Data from: Prevalence of coronary artery disease evaluated by coronary CT angiography in women with mammographically detected breast arterial calcifications

Leila Mostafavi, Wanda Marfori, Cesar Arellano, Alessia Tognolini, William Speier, Ali Adibi & Stefan G. Ruehm
To assess the correlation between breast arterial calcifications (BAC) on digital mammography and the extent of coronary artery disease (CAD) diagnosed with dual source coronary computed tomography angiography (CTA) in a population of women both symptomatic and asymptomatic for coronary artery disease. 100 consecutive women (aged 34 – 86 years) who underwent both coronary CTA and digital mammography were included in the study. Health records were reviewed to determine the presence of cardiovascular risk factors...

Data from: Natural selection on floral morphology depends on climate

Diane R. Campbell & John M. Powers
Climate has the potential to influence evolution, but how it influences the strength or direction of natural selection is largely unknown. We quantified the strength of selection on four floral traits of the subalpine herb Ipomopsis sp. in 10 years that differed in precipitation, causing extreme temporal variation in the date of snowmelt in the Colorado Rocky Mountains. The chosen floral traits were under selection by hummingbird and hawkmoth pollinators, with hawkmoth abundance highly variable...

Data from: Multicopy single-stranded DNA directs intestinal colonization of enteric pathogens

Johanna R. Elfenbein, Leigh A. Knodler, Ernesto S. Nakayasu, Charles Ansong, Heather M. Brewer, Lydia Bogomolnaya, L. Garry Adams, Michael McClelland, Joshua N. Adkins & Helene L. Andrews-Polymenis
Multicopy single-stranded DNAs (msDNAs) are hybrid RNA-DNA molecules encoded on retroelements called retrons and produced by the action of retron reverse transcriptases. Retrons are widespread in bacteria but the natural function of msDNA has remained elusive despite 30 years of study. The major roadblock to elucidation of the function of these unique molecules has been the lack of any identifiable phenotypes for mutants unable to make msDNA. We report that msDNA of the zoonotic pathogen...

Data from: Selection analysis on the rapid evolution of a secondary sexual trait

Swanne P. Gordon, David Reznick, Jeffrey D. Arendt, Allen Roughton, Michelle N. Ontiveros Hernandez, Paul Bentzen, Andrés López-Sepulcre & Jeff D. Arendt
Evolutionary analyses of population translocations (experimental or accidental) have been important in demonstrating speed of evolution because they subject organisms to abrupt environmental changes that create an episode of selection. However, the strength of selection in such studies is rarely measured, limiting our understanding of the evolutionary process. This contrasts with long-term, mark–recapture studies of unmanipulated populations that measure selection directly, yet rarely reveal evolutionary change. Here, we present a study of experimental evolution of...

Data from: Test of biotic and abiotic correlates of latitudinal variation in defences in the perennial herb Ruellia nudiflora

Luis Abdala-Roberts, Xoaquín Moreira, Sergio Rasmann, Victor Parra-Tabla & Kailen A. Mooney
1. Geographic variation in abiotic factors and species interactions is widespread and is hypothesized to generate concomitant patterns of species trait variation. For example, higher rates of herbivory at lower latitudes are thought to select for increased plant defences, although latitudinal variation in defences may also be influenced directly by abiotic factors and indirectly by predators and parasitoids reducing herbivore pressure. 2. We measured defences of the herb Ruellia nudiflora among 30 populations spanning a...
