Human adults with normal vision can combine visual landmark and non-visual self-motion cues to improve their navigational precision. Here we asked whether blind individuals treated with a retinal prosthesis could also benefit from using the resultant new visual signal together with non-visual information when navigating. Four patients (blind for 15-52 years) implanted with the Argus II retinal prosthesis (Second Sight Medical Products Inc. Sylmar, CA), and five age-matched and six younger controls, participated. Participants completed...
Data from: Geographical variation in species' population responses to changes in temperature and precipitationJames W. Pearce-Higgins, Nancy Ockendon, David J. Baker, Jamie Carr, Elizabeth C. White, Rosamunde E. A. Almond, Tatsuya Amano, Esther Bertram, Richard B. Bradbury, Cassie Bradley, Stuart H. M. Butchart, Nathalie Doswald, Wendy Foden, David J. C. Gill, Rhys E. Green, William J. Sutherland & Edmund V. J. Tanner
Despite increasing concerns about the vulnerability of species’ populations to climate change, there has been little overall synthesis of how individual population responses to variation in climate differ between taxa, with trophic level or geographically. To address this, we extracted data from 132 long-term (≥20 years) studies of population responses to temperature and precipitation covering 236 animal and plant species across terrestrial and freshwater habitats. Temperature tended to have a greater overall impact on populations...
Data from: SNP discovery in non-model organisms: strand-bias and base-substitution errors reduce conversion ratesAnders Gonçalves Da Silva, William Barendse, James W. Kijas, Wes C. Barris, Sean McWilliam, Rowan J. Bunch, Russell McCulloch, Blair Harrison, A. Rus Hoelzel, Phillip R. England & Russell McCullough
Single nucleotide polymorphisms (SNPs) have become the marker of choice for genetic studies in organisms of conservation, commercial or biological interest. Most SNP discovery projects in nonmodel organisms apply a strategy for identifying putative SNPs based on filtering rules that account for random sequencing errors. Here, we analyse data used to develop 4723 novel SNPs for the commercially important deep-sea fish, orange roughy (Hoplostethus atlanticus), to assess the impact of not accounting for systematic sequencing...
Data from: Contrasting population genetic structure among freshwater-resident and anadromous lampreys: the role of demographic history, differential dispersal, and anthropogenic barriers to movement.Fiona S. A. Bracken, A. Rus Hoelzel, John B. Hume & Martyn C. Lucas
The tendency of many species to abandon migration remains a poorly understood aspect of evolutionary biology that may play an important role in promoting species radiation by both allopatric and sympatric mechanisms. Anadromy inherently offers an opportunity for the colonization of freshwater environments, and the shift from an anadromous to a wholly freshwater life history has occurred in many families of fishes. Freshwater-resident forms have arisen repeatedly among lampreys (within the Petromyzontidae and Mordaciidae), and...
Data from: Seascape genetics along environmental gradients in the Arabian Peninsula: insights from ddRAD sequencing of anemonefishesPablo Saenz-Agudelo, Joseph D. DiBattista, Marek J. Piatek, Michelle R. Gaither, Hugo B. Harrison, Gerrit B. Nanninga & Michael L. Berumen
Understanding the processes that shape patterns of genetic structure across space is a central aim of landscape genetics. However, it remains unclear how geographic features and environmental variables shape gene flow, particularly for marine species in large complex seascapes. Here, we evaluated the genomic composition of the two-band anemonefish Amphiprion bicinctus across its entire geographic range in the Red Sea and Gulf of Aden, as well as its close relative, Amphiprion omanensis endemic to the...
Data from: Cultural traditions across a migratory network shape the genetic structure of southern right whales around Australia and New ZealandE. L. Carroll, C. S. Baker, M. Watson, R. Alderman, J. Bannister, O. E. Gaggiotti, D. R. Gröcke, N. Patenaude & R. Harcourt
Fidelity to migratory destinations is an important driver of connectivity in marine and avian species. Here we assess the role of maternally directed learning of migratory habitats, or migratory culture, on the population structure of the endangered Australian and New Zealand southern right whale. Using DNA profiles, comprising mitochondrial DNA (mtDNA) haplotypes (500 bp), microsatellite genotypes (17 loci) and sex from 128 individually-identified whales, we find significant differentiation among winter calving grounds based on both...
The drivers of speciation remain among the most controversial topics in evolutionary biology. Initially, Darwin emphasized natural selection as a primary mechanism of speciation, but the architects of the modern synthesis largely abandoned that view in favour of divergence by geographic isolation. The balance between selection and isolation is still at the forefront of the evolutionary debate, especially for the world's tropical oceans where biodiversity is high, but isolating barriers are few. Here, we identify...
The evolution of island populations in natural systems is driven by local adaptation and genetic drift. However, evolutionary pathways may be altered by humans in several ways. The wild boar (WB) (Sus scrofa) is an iconic game species occurring in several islands, where it has been strongly managed since prehistoric times. We examined genomic diversity at 49 803 single-nucleotide polymorphisms in 99 Sardinian WBs and compared them with 196 wild specimens from mainland Europe and...
