Summary New analytical tools applied to long‐term data demonstrate that ecological communities are highly dynamic over time. We developed an r package, library(“codyn”) , help ecologists easily implement these metrics and gain broader insights into community dynamics. provides temporal diversity indices stability metrics. All functions designed be implemented multiple replicates. Temporal include species turnover, mean rank shifts rate of change Community calculate overall patterns...
Abstract The first Provenance Challenge was set up in order to provide a forum for the community understand capabilities of different provenance systems and expressiveness their representations. To this end, functional magnetic resonance imaging workflow defined, which participants had either simulate or run produce some representation, from identified queries be implemented executed. Sixteen teams responded challenge, submitted inputs. In paper, we present challenge queries, summarize...
In recent years, a number of data identification technologies have been developed which purport to permanently identify digital objects. this paper, nine and systems for assigning persistent identifiers are assessed their applicability Earth science (ARKs, DOIs, XRIs, Handles, LSIDs, OIDs, PURLs, URIs/URNs/URLs, UUIDs). The evaluation used four use cases that focused on the suitability each scheme provide Unique Identifiers objects, Locators serve as Citable Locators, uniquely scientific...
Abstract The Earth System Science Server (ES3) project is developing a local infrastructure for managing science data products derived from satellite remote sensing. By ‘local,’ we mean the that scientist uses to manage creation and dissemination of her own products, particularly those are constantly incorporating corrections or improvements based on scientist's research. Therefore, in addition being robust capacious enough support public access, ES3 intended be flexible idiosyncratic...
Many soil and water conservation (SWC) measures have been applied in the Jinghe River Basin to decrease erosion restore degraded vegetation cover. Analysis of historical streamflow records suggests that SWC may led declines streamflow, although climate human use contributed observed changes. This paper presents an application a watershed-scale, physically-based eco-hydrological model—the Regional Hydro-Ecological Simulation System (RHESSys)—in study impacts on streamflow. Several extensions...
We illustrate how combining retrospective and prospectiveprovenance can yield scientifically meaningful hybrid provenancerepresentations of the computational histories data produced during a script run. use scripts from multiple disciplines (astrophysics, climate science, biodiversity curation, social network analysis), implemented in Python, R, MATLAB, to highlight usefulness diverse forms retrospectiveprovenance when coupled with prospectiveprovenance. Users provide prospective provenance,...
DataONE has consistently focused on interoperability among data repositories to enable seamless access well-described the Earth and environment. Our existing services promote discovery through harmonization of diverse metadata specifications used across communities, our integrated search portal services. In terms FAIR principles, we have done a good job at Findable Accessible, while as community placed less emphasis Interoperable Reusable. We present new for quantitatively providing guidance...
