Data from: Interactive effects of disturbance and dispersal on community assembly

Miriam N. Ojima & Lin Jiang
The traditional debate on alternative community states has been over whether or not they exist. Studies of community assembly have examined the role of assembly history in driving community divergence, but the context in which assembly history becomes important is a continued topic of interest. In this study, we created communities of bacterivorous ciliated protists in laboratory microcosms and manipulated assembly history, disturbance frequency, and the presence of dispersal among local communities to investigate the...

Data from: Comparative system identification of flower tracking performance in three hawkmoth species reveals adaptations for dim light vision

Anna L. Stöckl, Klara Kihlström, Steven Chandler & Simon Sponberg
Flight control in insects is heavily dependent on vision. Thus, in dim light, the decreased reliability of visual signal detection also prompts consequences for insect flight. We have an emerging understanding of the neural mechanisms that different species employ to adapt the visual system to low light. However, much less explored are comparative analyses of how low light affects the flight behaviour of insect species, and the corresponding links between physiological adaptations and behaviour. We...

Data from: Manipulating virulence factor availability can have complex consequences for infections

Michael Weigert, Adin Ross-Gillespie, Anne Leinweber, Gabriella Pessi, Sam P. Brown & Rolf Kuemmerli
Given the rise of bacterial resistance against antibiotics, we urgently need alternative strategies to fight infections. Some propose we should disarm rather than kill bacteria, through targeted disruption of their virulence factors. It is assumed that this approach (i) induces weak selection for resistance because it should only minimally impact bacterial fitness, and (ii) is specific, only interfering with the virulence factor in question. Given that pathogenicity emerges from complex interactions between pathogens, hosts, and...

Data from: Predator identity influences metacommunity assembly

Nicole K. Johnston, Zhichao Pu & Lin Jiang
1.Predation is among the most important biotic factors influencing natural communities, yet we have a rather rudimentary understanding of its role in modulating metacommunity assembly. 2.We experimentally examined the effects of two different predators (a generalist and a specialist) on metacommunity assembly, using protist microcosm metacommunities that varied in predator identity, dispersal among local communities, and the history of species colonization into local communities. 3.Generalist predation resulted in reduced α diversity and increased β diversity...

Data from: Intoxicated copepods: ingesting toxic phytoplankton leads to risky behaviour

Rachel S. Lasley-Rasher, Kathryn Nagel, Aakanksha Angra & Jeannette Yen
Understanding interactions between harmful algal bloom (HAB) species and their grazers is essential for determining mechanisms of bloom proliferation and termination. We exposed the common calanoid copepod, Temora longicornis to the harmful algal bloom species Alexandrium fundyense and examined effects on copepod survival, ingestion, egg production and swimming behaviour. A. fundyense was readily ingested by T. longicornis and significantly altered copepod swimming behaviour without affecting copepod survival or fitness. A. fundyense caused T. longicornis to...

Data from: Phylogenetic context determines the role of competition in adaptive radiation

Jiaqi Tan, Matthew R. Slattery, Xian Yang & Lin Jiang
Understanding ecological mechanisms regulating the evolution of biodiversity is of much interest to ecologists and evolutionary biologists. Adaptive radiation constitutes an important evolutionary process that generates biodiversity. Competition has long been thought to influence adaptive radiation, but the directionality of its effect and associated mechanisms remain ambiguous. Here, we report a rigorous experimental test of the role of competition on adaptive radiation using the rapidly evolving bacterium Pseudomonas fluorescens SBW25 interacting with multiple bacterial species...

Data from: The multivariate association between genomewide DNA methylation and climate across the range of Arabidopsis thaliana

Thomas E. Keller, Jesse R. Lasky & Soojin V. Yi
Epigenetic changes can occur due to extracellular environmental conditions. Consequently, epigenetic mechanisms can play an intermediate role to translate environmental signals to intracellular changes. Such a role might be particularly important in plants, which often show strong local adaptation and have the potential for heritable epigenetic states. However, little is currently known about the role of epigenetic variation in the ecological mechanisms of adaptation. Here, we used multivariate redundancy analyses to examine genomewide associations between...

Data from: Force and torque on spherical particles in micro-channel flows using computational fluid dynamics

Jin Suo, Erin E. Edwards, Ananyaveena Anilkumar, Todd Sulchek, Don P. Giddens & Susan N. Thomas
To delineate the influence of hemodynamic force on cell adhesion processes, model in vitro fluidic assays that mimic physiological conditions are commonly employed. Herein, we offer a framework for solution of the three-dimensional Navier–Stokes equations using computational fluid dynamics (CFD) to estimate the forces resulting from fluid flow near a plane acting on a sphere that is either stationary or in free flow, and we compare these results to a widely used theoretical model that...
