Data from: Efficient inference of recombination hot regions in bacterial genomes

Koji Yahara, Xavier Didelot, M Azim. Ansari, Samuel K. Sheppard & Daniel Falush
In eukaryotes, detailed surveys of recombination rates have shown variation at multiple genomic scales and the presence of “hotspots” of highly elevated recombination. In bacteria, studies of recombination rate variation are less developed, in part because there are few analysis methods that take into account the clonal context within which bacterial evolution occurs. Here we focus in particular on identifying “hot regions” of the genome where DNA is transferred frequently between isolates. We present a...

Data from: Herbivore effect traits and their impact on plant community biomass: an experimental test using grasshoppers

Hélène Deraison, Isabelle Badenhausser, Luca Börger & Nicolas Gross
1. Using trait-based approaches to study trophic interactions may represent one of the most promising approaches to evaluate the impact of trophic interactions on ecosystem functioning. To achieve this goal, it is necessary to clearly identify which traits determine the impact of one trophic level on another. 2. Using functionally contrasting grasshopper species, we tested the ability of multiple traits (morphological, chemical and biomechanical) to predict herbivore impact on the biomass of a diverse plant...

Data from: Evidence of land-sea transfer of the zoonotic pathogen Campylobacter to a wildlife marine sentinel species

Johanna L. Baily, Guillaume Méric, Sion Bayliss, Geoffrey Foster, Simon E. Moss, Eleanor Watson, Ben Pascoe, Jane Mikhail, Robert J. Goldstone, Romain Pizzi, David G. E. Smith, Kim Willoughby, Alisa J. Hall, Mark P. Dagleish, Samuel K. Sheppard & Ailsa J. Hall
Environmental pollution often accompanies the expansion and urbanization of human populations where sewage and wastewaters commonly have an impact on the marine environments. Here, we explored the potential for faecal bacterial pathogens, of anthropic origin, to spread to marine wildlife in coastal areas. The common zoonotic bacterium Campylobacter was isolated from grey seals (Halichoerus grypus), an important sentinel species for environmental pollution, and compared to isolates from wild birds, agricultural sources and clinical samples to...

Data from: Pan-Atlantic analysis of the overlap of a highly migratory species, the leatherback turtle, with pelagic longline fisheries

Coyne, Andres Domingo, Scott Eckert, Daniel Evans, Alejandro Fallabrino, Sandra Ferraroli, Angela Formia, Bruno Giffoni, Graeme C. Hays, George Hughes, Laurent Kelle, Aimee Leslie, Milagros López-Mendilaharsu, Paolo Luschi, Laura Prosdocimi, Sergio Rodriguez-Heredia, Avanaisa Turny … & Brendan J. Godley
Large oceanic migrants play important roles in ecosystems, yet many species are of conservation concern as a result of anthropogenic threats, of which incidental capture by fisheries is frequently identified. The last large populations of the leatherback turtle, Dermochelys coriacea, occur in the Atlantic Ocean, but interactions with industrial fisheries could jeopardize recent positive population trends, making bycatch mitigation a priority. Here, we perform the first pan-Atlantic analysis of spatio-temporal distribution of the leatherback turtle...

Data from: Cryptic ecology among host generalist Campylobacter jejuni in domestic animals

Strachan, Ken Forbes, Frances M. Colles, Keith A. Jolley, Stephen D. Bentley, Martin C. J. Maiden, Marja-Liisa Hänninen, Julian Parkhill, William P. Hanage & Jukka Corander
Homologous recombination between bacterial strains is theoretically capable of preventing the separation of daughter clusters, and producing cohesive clouds of genotypes in sequence space. However, numerous barriers to recombination are known. Barriers may be essential such as adaptive incompatibility, or ecological, which is associated with the opportunities for recombination in the natural habitat. Campylobacter jejuni is a gut colonizer of numerous animal species and a major human enteric pathogen. We demonstrate that the two major...
