2007 pre-treatment soils pH, nutrients, texture:Nutrient Network: A cross-site investigation of bottom-up control over herbaceous plant community dynamics and ecosystem function.
This experiment is one implementation of a globally distributed experiment, known as the Nutrient Network. At Cedar Creek, as in over 70 other sites in grasslands around the world, the experiment aims to describe impacts of increased nutrients (nitrogen, phosphorus, potassium, sulfur and other metals) and decreased herbivory (removal of mammals by fencing). Two overarching questions are being explored with these manipulations: 1. To what extent are plant production and diversity co-limited by multiple nutrients in herbaceous-dominated communities? 2. Under what conditions do grazers or fertilization control plant biomass, diversity, and composition? By utilizing identical protocols at diverse grassland sites around the world, NutNet aims to uncover both the generalities in ecosystem functioning, and the contingencies or differences which can obscure those common mechanisms. In addition to the standard NutNet protocol, e247 includes an additional low Nitrogen gradient (1 gram Nitrogen per meter squared per year and 5 grams Nitrogen per meter squared per year in addition to the standard 10 grams Nitrogen per meter squared per year).

Congruence checks for EML-described datasets in the Long Term Ecological Research (LTER) Network, Checks described as of 2015
These data are descriptions of all checks contributed to the LTER EML Congruence Checker as of late 2015. The EML Congruence Checker (ECC) informs contributors about the structure of the data package, indicating whether the asserted metadata accurately defines the data entity (table); this is called “structural congruence”. The checks and checking software are discussed in O'Brien, M. C, D. Costa and M. Servilla. 2016. Ensuring the quality of data packages in the LTER network data management system. Ecological Informatics. DOI: 10.1016/j.ecoinf.2016.08.001. Data are organized into a flat table, with one row per check. Each check is characterized with multiple typologies including priority, justification, scope (community), response behavior type and data packaging aspect. Operational information for software includes EML path, criteria for pass/fail, response expected, sample datasets for both pass and fail responses, with failure notes. Management fields indicate if the check has been implemented or not (as of paper publication), with dates when the check was added or updated.
EML congruence checker reports from the Long Term Ecological Research Network PASTA system, 2013-2015
These data are results of LTER EML Congruence Checker reports from 9,353 data packages from 2013 to 2015, by 27 current and former LTER sites, plus ad hoc packages contributed by the Network. All data were gleaned from publicly available reports that accompany each data package at upload. These data and related checks and checking software are discussed in O'Brien, M. C, D. Costa and M. Servilla. 2016. Ensuring the quality of data packages in the LTER network data management system. Ecological Informatics. DOI: 10.1016/j.ecoinf.2016.08.001. Data are organized into a denormalized flat table, with one row per check run (nultiple rows per dataset and per entity). No data for error-responses are present, since these data are from uploaded datasets, and datasets with errors are not accepted.
Saturated and unsaturated hydraulic conductivity for Saddle Stream Network, 2017
Saturated and unsaturated hydraulic conductivity are important surface hydrologic properties that dictate the how fast water moves into the subsurface. Saturated and unsaturated hydraulic conductivity were measured at approximately 25 locations throughout the Niwot Ridge Saddle Stream Catchment in 2017. Saturated hydraulic conductivity was calculated from saturated infiltration rates determined using a single-ring infiltrometer. Unsaturated hydraulic conductivity was calculated from unsaturated infiltration rates determined using a mini-disk portable tension infiltrometer. Both measurements had over an order of magnitude variation across the catchment, suggesting a wide range in hydrologic function. Replicate measurements within 1m^2 were often comparable, but at some sites showed large differences. These differences likely reflect the small-scale variability in subsurface characteristics across the catchment.
Soil loss on ignition for Saddle Stream Network, 2017
Soil loss on ignition (LOI), as a proxy for total soil organic matter, is an important control on surface hydrology. To measure soil LOI across the Niwot Ridge LTER Saddle Stream Catchment, surface (0 – 10 cm) soil samples (n = 84) were collected on roughly a 60 x 60 m grid, including sensor network sites. After drying, sieving to < 2mm, and grinding to a fine powder, a ~20 g subsample of soil was combusted at 550°C for 4 hours. LOI is reported as a percent difference between dry weights at 550°C and 105°C. The average LOI was 19.23%, but soils had a wide range from 4.80% to 46.77%. This dataset is useful for studies of spatial patterns in organic matter accumulation, biogeochemical process rates, and surface hydrology.
Soil moisture and temperature surveys for Saddle Stream Network, 2017
Surface soil moisture and temperature reflect patterns in snowmelt and hydrologic connectivity in alpine ecosystems. In the summer of 2017, surface soil moisture and temperature were measured on eight surveys at 84 locations in the Niwot Ridge Saddle Stream catchment. The eight surveys were July 3, 2017 – September 9, 2017. Overall, soil moisture showed the influence of snowmelt early in the season and equilibration of soil moisture during the summer monsoon. Seasonal patterns in soil temperature were opposite that of soil moisture in that temperatures increased until the summer monsoon, which cooled surface soils temporarily. Soil moisture was highly variable between locations in that some locations remained consistently dry, while others remained consistently wet. Still others experienced an order of magnitude of variation in soil moisture over the course of the season. These data are useful for validating hydrologic models and remotely sensed thermal and moisture properties, informing growing season plant phenology, and understanding hydrologic connectivity in alpine ecosystems.
Soil texture for Saddle Stream Network, 2017
Soil texture is an important hydrologic control. To measure soil texture across the Niwot Ridge LTER Saddle Stream Catchment, surface (0 – 10 cm) soil samples (n = 84) were collected on roughly a 60 x 60 m grid, including sensor network sites. After drying and sieving to less than 2mm, soil size fractions (percent sand, silt, and clay) and corresponding soil texture were determined by laser particle size analysis. Soil size fractions and texture are reported using both United States Department of Agriculture and World Reference Base soil classification standards. Soils were one of four textures: loamy sand, silt loam, sandy loam, and loam. Over half of the soils sampled were sandy loam. This dataset is useful for hydrologic modeling studies and other studies related to understanding alpine hydrology.
Stream Order for drainage to streams in the Ipswich or Parker River Network - ASCII Raster File
This datalayer is a gridded data set that identifies for each pixel the stream order that drainage from the pixel initially enters into the river network. The resolution is 120 m x 120 m. Based on the flow direction in: WAT-RGIS-120m-FlowDirection.asc. First order streams at the 120m resolution are equivalent to third order when calculated at the pixel level from the drainage direction grid (i.e. 3rd order pixels are equivalent to 1st order streams, 4th order pixels are second order streams, etc). Idenitify the distribution of inputs from land to streams of different sizes.

European Procurement Markets as Bipartite Networks

Data is sourced from Tenders Electronic Daily (TED), the official procurement portal of the European Union.</p> <p>Nodes with the suffix "_i" are issuers (sometimes referred to as buyers) of public contracts, for instance public hospitals, ministries, local governments. Nodes with the suffix "_w" are winners (sometimes called suppliers) of public contracts, generally private-sector firms. Identities have been statistically deduplicated, as described in the paper. </p> <p>Each network is bipartite: edges only exist between issuers and winners. Edges represent contracting relationships and have two attributes: </p> <ul> <li>``count'' measures the volume of contracts between the issuer and winner in the given year. This attribute can be interpreted as a weight or strength of the relationship.</li> <li>``pctSingleBid'' describes the share of contracts between the issuer and winner awarded without competition, i.e. with the winner as single bidder or sole-supplier. Note: missing data on single-bidding is imputed. This is an elementary indicator of corruption risk of the contract. For more information consult the paper referenced above.</li> </ul> <p>Ids of issuers and winners are consistent across time and within countries. Node ids have been randomly generated and do not correspond to any official statistics.</p> <p>The networks are stored in the GML format. For example: they can be read in directly by Gephi or by the Python NetworkX library with the following commands (using the 2010 Portuguese market as an example):</p> <blockquote> <p> import networkx as nx<br> G=nx.read_gml('country_year_networks/PT_2010.gml')</p> </blockquote>
