Data from: Maintenance of genetic diversity in an introduced island population of Guanacos after seven decades and two severe demographic bottlenecks: implications for camelid conservation

Benito A. González, Pablo Orozco-TerWengel, Rainer Von Borries, Warren E. Johnson, William L. Franklin & Juan C. Marín
Fifteen Guanacos were introduced to Staats Island in Falklands/Malvinas archipelago from Patagonia in the 1930s. After introduction, the Guanaco population increased to almost 400 animals that retained a footprint of the founding effect and bottleneck reflected in the genetic status of this isolated population. The goals of this study were to (i) make a genetic assessment of this island population through comparisons with mainland populations and simulation, and (ii) assess the likely source population of...

Data from: Reconstructing the demographic history of orang-utans using approximate Bayesian computation

Investigating how different evolutionary forces have shaped patterns of DNA variation within and among species requires detailed knowledge of their demographic history. Orang-utans, whose distribution is currently restricted to the Southeast Asian islands of Borneo (Pongo pygmaeus) and Sumatra (Pongo abelii), have likely experienced a complex demographic history, influenced by recurrent changes in climate and sea levels, volcanic activities and anthropogenic pressures. Using the most extensive sample set of wild orang-utans to date, we employed...

Data from: A new earthworm species within a controversial genus: Eiseniona gerardoi sp. n. (Annelida, Lumbricidae) - description based on morphological and molecular data.

Marta Novo, Rosa Fernández, Mónica Gutiérrez, Dario J. Díaz Cosín, Daniel Fernández Marchán & Dario Diaz Cosin
The morphological and anatomical simplicity of soil dwelling animals, such as earthworms, has limited the establishment of a robust taxonomy making it sometimes subjective to authors’ criteria. Within this context, integrative approaches including molecular information are becoming more popular to solve the phylogenetic positioning of conflictive taxa. Here we present the description of a new lumbricid species from the region of Extremadura (Spain), Eiseniona gerardoi sp. n. The assignment to this genus is based on...

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...

Data from: Nucleus reuniens of the thalamus contains head direction cells

Maciej M. Jankowski, , Nicholas F. Wright, Seralynne D. Vann, Jonathan T. Erichsen, John P. Aggleton, Shane M. O’Mara & Shane M O'Mara
Discrete populations of brain cells signal heading direction, rather like a compass. These ‘head direction’ cells are largely confined to a closely-connected network of sites. We describe, for the first time, a population of head direction cells in nucleus reuniens of the thalamus in the freely-moving rat. This novel subcortical head direction signal potentially modulates the hippocampal CA fields directly and, thus, informs spatial processing and memory.

Data from: An holistic ecological analysis of the diet of Cory’s shearwaters using prey morphological characters and DNA barcoding

Hany Alonso, José Pedro Granadeiro, Silke Waap, José Xavier, William O. C. Symondson, Jaime A. Ramos & Paulo Catry
Knowledge of the dietary choices and trophic niches of organisms is the key to understanding their roles in ecosystems. In seabird diet studies, prey identification is a difficult challenge, often yielding results with technique-specific biases. Additionally, sampling efforts are often not extensive enough to reveal intra-populational variation. Immature animals, which may constitute up to 50% of a population, may occupy a significantly different trophic niche to more-experienced birds, but this remains largely unexplored. We investigated...

Data from: Comparative evaluation of potential indicators and temporal sampling protocols for monitoring genetic erosion

Sean Hoban, Jan A. Arntzen, Michael W. Bruford, José A. Godoy, A. Rus Hoelzel, Gernot Segelbacher, Carles Vilà & Giorgio Bertorelle
Genetic biodiversity contributes to individual fitness, species' evolutionary potential, and ecosystem stability. Temporal monitoring of the genetic status and trends of wild populations' genetic diversity can provide vital data to inform policy decisions and management actions. However, there is a lack of knowledge regarding which genetic metrics, temporal sampling protocols, and genetic markers are sufficiently sensitive and robust, on conservation-relevant timescales. Here, we tested six genetic metrics and various sampling protocols (number and arrangement of...
