Data from: Costs and benefits of non-random seed release for long distance dispersal in wind-dispersed plant species

Jelle Treep, Monique De Jager, Leandra S. Kuiper, Tomer Duman, Gabriel G. Katul & Merel B. Soons
The dispersal ability of plants is a major factor driving ecological responses to global change. In wind-dispersed plant species, non-random seed release in relation to wind speeds has been identified as a major determinant of dispersal distances. However, little information is available about the costs and benefits of non-random abscission and the consequences of timing for dispersal distances. We asked: 1) To what extent is non-random abscission able to promote long-distance dispersal and what is...

Data from: Development and usability testing of an audit and feedback tool for anesthesiologists

Atilio Barbeito & Noa Segall
Background: We describe the creation and evaluation of a personal audit & feedback (A&F) tool for anesthesiologists. Methods: A survey aimed at capturing barriers for personal improvement efforts and feedback preferences was administered to attending anesthesiologists. The results informed the design and implementation of 4 dashboards that display information on individual practice characteristics as well as comparative performance on several quality metrics. The dashboards’ usability was then tested using the human-centered design framework. Results: Anesthesiologists...

The current extinction and climate change crises pressure us to predict population dynamics with ever-greater accuracy. Although predictions rest on the well-advanced theory of age-structured populations, two key issues remain poorly-explored. Specifically, how the age-dependency in demographic rates and the year-to-year interactions between survival and fecundity affect stochastic population growth rates. We use inference, simulations, and mathematical derivations to explore how environmental perturbations determine population growth rates for populations with different age-specific demographic rates and...

Data from: Gene flow, divergent selection and resistance to introgression in two species of morning glories (Ipomoea)

Joanna L. Rifkin, Allan S. Castillo, Irene T. Liao & Mark D. Rausher
Gene flow is thought to impede genetic divergence and speciation by homogenizing genomes. Recent theory and research suggests that strong enough divergent selection can overpower gene flow, leading to islands of divergence. However, there are alternative explanations for these patterns. Independent evidence that islands of divergence are due to divergent selection would allow these explanations to be distinguished, but such evidence is scarce. Here we present multiple lines of evidence that islands of divergence in...
