Data from: Revisiting Brownian motion as a description of animal movement: a comparison to experimental movement dataDaniel Bearup, Carly M. Benefer, Sergei V. Petrovskii & Rod P. Blackshaw
Characterization of patterns of animal movement is a major challenge in ecology with applications to conservation, biological invasions and pest monitoring. Brownian random walks, and diffusive flux as their mean field counterpart, provide one framework in which to consider this problem. However, it remains subject to debate and controversy. This study presents a test of the diffusion framework using movement data obtained from controlled experiments. Walking beetles (Tenebrio molitor) were released in an open circular...
Data from: Weaponry and defenses in fighting animals: how allometry can alter predictions from contest theoryAlexandre Palaoro & Mark Briffa
Theoretical models have been developed to understand how animals decide to withdraw from a contest. They provide testable predictions regarding the relationship between resource holding potential (RHP) and contest duration that assume linear relationships among RHP traits. However, RHP traits might scale with body size according to power laws. Furthermore, investment across different RHP traits may vary. Herein, we provide a model that encompasses the allometric relationship between body size and other RHP traits. First,...
Data from: Can plan recommendations improve the coverage decisions of vulnerable populations in health insurance marketplaces?Andrew J. Barnes, Yaniv Hanoch & Thomas Rice
Objective: The Affordable Care Act’s marketplaces present an important opportunity for expanding coverage but consumers face enormous challenges in navigating through enrollment and re-enrollment. We tested the effectiveness of a behaviorally informed policy tool—plan recommendations—in improving marketplace decisions. Study Setting: Data were gathered from a community sample of 656 lower-income, minority, rural residents of Virginia. Study Design: We conducted an incentive-compatible, computer-based experiment using a hypothetical marketplace like the one consumers face in the federally-facilitated...
Fish exhibit impaired sensory function and altered behaviour at levels of ocean acidification expected to occur owing to anthropogenic carbon dioxide emissions during this century. We provide the first evidence of the effects of ocean acidification on reproductive behaviour of fish in the wild. Satellite and sneaker male ocellated wrasse (Symphodus ocellatus) compete to fertilize eggs guarded by dominant nesting males. Key mating behaviours such as dominant male courtship and nest defence did not differ...
Data from: An experimental comparison of three Towed Underwater Video Systems using species metrics, benthic impact and performanceEmma V. Sheehan, Sandrine Vaz, Erin Pettifer, Nicola L. Foster, Sarah J. Nancollas, Sophie Cousens, Luke Holmes, Jean-Valery Facq, Gregory Germain & Martin J. Attrill
1. Managing ecological systems, which operate over large spatial scales is inherently difficult and often requires sourcing data from different countries and organizations. The assumption might be made that data collected using similar methodologies are comparable but this is rarely tested. Here, benthic video data recorded using different towed underwater video systems (TUVSs) were experimentally compared. 2. Three technically different TUVSs were compared on different seabed types (rocky, mixed ground and sandy) in Kingmere Marine...
