Fedora4: The Open Linked Data Platform

Presentation at Open Repositories 2015 (OR2015), the 10th International Conference on Open Repositories, Indianapolis, Indiana, in session P1A: Linked Open Data (LOD). Note that high quality video files for this talk were not obtainable, so some video quality problems may be noticed. Linked Open Data has moved from being a buzzword to a fundamental building block of modern repositories and information systems. Its explosion, taking in this domain the form of scholarly and scientific datasets, publications, annotations, cultural heritage descriptions and other repository-based content, offers unprecedented opportunity for scientific and societal advancement. It is the interconnections that integrate systems and resources, however, that turn disparate ideas into unanticipated solutions. The Open Repositories community largely understands the value of linked data. The trouble has been in answering the question of “how?” to do this together, rather than "why?" do it at all. In order to be effective, we need to have solid guidelines, common practices, and well specified toolsets and products. A confluence of developments has opened the door to exactly this. In October of 2012, the initial W3C working draft of the Linked Data Platform 1.0 (LDP) document was published[2]. In July of 2012, the demand for a next-generation Fedora platform was channeled into the Fedora 4 (F4) project, which at the time was termed Fedora Futures. The alignment of these two stars set in motion events that provided both requirements and solutions for the community.

Concentrations and Yields of Total Hg and MeHg in Large Boreal Rivers Linked to Water and Wetland Coverage in the Watersheds

Large rivers are major contributors of mercury (Hg) exports to the ocean, as they integrate processes of loading and loss occurring at the watershed level. Within a watershed, stream-scale studies have revealed that specific landscape features, such as wetlands or lakes, are hotspots for Hg and methylmercury (MeHg) loading, sinks and transformation, but we still do not know how these landscape features operate at the whole network scale and over large geographic gradients. In this study, we evaluate how landscape metrics (vegetation types, wetland and lake cover, climate, hydrology) are related to riverine concentrations and watershed yields of Hg and MeHg in 18 large boreal rivers draining watersheds that range from 44 km2 to 209 453 km2, distributed along a 650 km latitudinal transect in the James Bay region of Québec. Our results reinforce the role of wetlands as sources of MeHg, but further show that surface coverage of water in the watershed is the major driver of both Hg and MeHg concentrations and exports to the coast at the whole network scale. Our findings also demonstrate that seasonality modulates the relationship between landscape features and the various Hg forms. Based on hydrometric data, we additionally estimate annual exports for the whole Eastern James Bay to 441 kg Hg and 15 kg MeHg, for an average landscape yield of 1.24 g Hg km-2 y-1 and 0.041 g MeHg km-2 y-1. Our study provides tools to broadly predict riverine Hg concentrations and exports with only a few easily accessible landscape metrics.

Microsatellite genotyping data for habitat-linked genetic structure for white-crowned sparrow (Zonotrichia leucophrys): local factors shape population genetic structure

Ecological, environmental, and geographic factors all influence genetic structure. Species with broad distributions are ideal systems because they cover a range of ecological and environmental conditions allowing us to test which components predict genetic structure. This study presents a novel, broad geographic approach using molecular markers, morphology, and habitat modelling to investigate rangewide and local barriers causing contemporary genetic differentiation within the geographical range of three white-crowned sparrow (Zonotrichia leucophrys) subspecies: Z. l. gambelii, Z. l. oriantha, and Z. l. pugetensis. Three types of genetic markers showed geographic distance between sampling sites, elevation, and ecosystem type are key factors contributing to population genetic structure. Microsatellite markers revealed white-crowned sparrows do not group by subspecies, but instead indicated four groupings at a rangewide scale and two groupings based on coniferous and deciduous ecosystems at a local scale. Our analyses of morphological variation also revealed habitat differences; sparrows from deciduous ecosystems are larger than individuals from coniferous ecosystems based on principal component analyses. Habitat modeling showed isolation by distance was prevalent in describing genetic structure, but isolation by resistance also had a small but significant influence. Not only do these findings have implications concerning the accuracy of subspecies delineations, they also highlight the critical role of local factors such as habitat in shaping contemporary population genetic structure of species with high dispersal ability.

Data from: White plumage color as an honest indicator: feather macrostructure links reflectance with reproductive effort and success

The structural condition of feathers may generally have a decisive role in shaping the color properties of the plumage. However, the information content of structurally mediated color differences is poorly known. This makes it particularly hard to determine the meaning of color variation in pigment-free white plumage patches. The white wing patch of the collared flycatcher (Ficedula albicollis) is an important sexual trait, and changes in its reflectance are partly due to macrostructural condition. We used two years of macrostructural, reflectance and breeding data from both sexes to examine whether wing patch macrostructure lends information content to actual reflectance in terms of reproductive effort and success. Macrostructure strongly predicted actual reflectance in males but only weakly in females. Furthermore, in males, feather vane width was related positively to current year reproductive effort, and negatively to previous year reproductive effort. This indicates that macrostructurally mediated reflectance attributes may inform the receiver not only of actual reproductive capacity but also of individual quality via reproductive costs.
