Abiotic and Biotic Variables Influencing Ranavirosis Occurrence.

<p>Model estimates and 95% confidence intervals for top ranking parameters Δ<i>AIC</i> <6 for ranavirosis occurrence (Criteria 1; [<a href="http://www.plosone.org/article/info:doi/10.1371/journal.pone.0127037#pone.0127037.ref009" target="_blank">9</a>]). Zero is indicated with a dotted line to demonstrate the importance of parameters in which confidence intervals do not overlap zero. Effect sizes above zero denote a positive relationship between each variable and ranavirosis occurrence.</p

Anthropogenic and Ecological Drivers of Amphibian Disease (Ranavirosis)

<div><p>Ranaviruses are causing mass amphibian die-offs in North America, Europe and Asia, and have been implicated in the decline of common frog (<i>Rana temporaria</i>) populations in the UK. Despite this, we have very little understanding of the environmental drivers of disease occurrence and prevalence. Using a long term (1992-2000) dataset of public reports of amphibian mortalities, we assess a set of potential predictors of the occurrence and prevalence of <i>Ranavirus</i>-consistent common frog mortality events in Britain. We reveal the influence of biotic and abiotic drivers of this disease, with many of these abiotic characteristics being anthropogenic. Whilst controlling for the geographic distribution of mortality events, disease prevalence increases with increasing frog population density, presence of fish and wild newts, increasing pond depth and the use of garden chemicals. The presence of an alternative host reduces prevalence, potentially indicating a dilution effect. Ranavirosis occurrence is associated with the presence of toads, an urban setting and the use of fish care products, providing insight into the causes of emergence of disease. Links between occurrence, prevalence, pond characteristics and garden management practices provides useful management implications for reducing the impacts of <i>Ranavirus</i> in the wild.</p></div

Maps showing the temperature data collected by the 2 Sonic Kayaks at the British Science Festival.

<p>Each map shows data from 1 of the kayak systems, with the 4 consecutive trips overlaid. Blue indicates lower temperatures while red indicates higher temperatures. This demonstrates the possibilities for obtaining very fine-scale maps of temperature data over space and time. The temperature information was overlaid with Esri base layer map tiles using the folium leaflet.js python library.</p

Abiotic and Biotic Variables Influencing Ranavirosis Prevalence.

Zero is indicated with a dotted line to demonstrate the importance of parameters in which confidence intervals do not overlap zero. Effect sizes below zero indicate a negative relationship between the variable and ranavirosis prevalence and effect sizes above zero indicate a positive relationship.</p

Microsatellite genotypes of European lobsters

Genotype data at up to 15 microsatellite loci for 612 lobsters from 28 locations. The first 312 samples at top comprise fine-scale samples all taken within Cornwall, UK, and have also been used to calculate regional allele frequencies in the 2015 PLOS ONE publication by Ellis et al; Genotype Reconstruction of Paternity in European Lobsters (Homarus gammarus). The next 300 individuals comprise broad-scale European population genetic samples
