title: Insights on community dynamics from large-scale, long-term data: time series for zooplankton and environmental variates from 35 North American lakes

description: NCEAS-1998-2244-NonDist-Dataset: The NCEAS Community Dynamics Working Group brought together theoretical and empirical ecologists to evaluate the relative importance of intrinsic and extrinsic sources of variability in natural communities. We focused on zooplankton community dynamics, in part because we had access to extensive time series data on zooplankton community structure from 35 North American lakes. Thirty-four of the lakes were concentrated at 5 sites: the North Temperate Lakes LTER site in Wisconsin; the University of Notre Dame Environmental Research Center in Michigan; the Dorset Environmental Research Centre, the Experimental Lakes Area, and the Sudbury region, all in Ontario. We also have data for saline Mono Lake in California. Our database has many strengths, including the length of the time series (5-21 years); consistent sampling methodologies, particularly for zooplankton; and the availability of information on environmental factors, including phytoplankton, physical parameters, and water chemistry. Another unique aspect of our dataset is that it includes data from both undisturbed reference lakes and experimentally manipulated lakes. The whole-lake experiments include food web manipulations, nutrient enrichments, acidifications and limings, and an unplanned invasion of an exotic species. Some of the experimental manipulations are even replicated within and among sites, providing a unique opportunity to explore the extent to which responses to a particular perturbation are consistent across lakes. In addition to determining how manipulations change the dynamics of zooplankton communities, we are using the data from the reference lakes to establish bounds on

In addition to determining how manipulations change the dynamics of zooplankton communities, we are using the data from the reference lakes to establish bounds on normal ranges of variability and to explore how this variability differs among lakes at a site vs. between sites. Thus, our joint database is facilitating extensive comparisons of zooplankton community dynamics at the scale of whole lakes.

title: Counts of gypsy moths in pheromone traps in the Central Appalachian Mountains

description: These are counts of gypsy moths, Lymantria dispar, in pheromone traps and counts of egg masses. They were collected as part of a gypsy moth management program in portions of the central Appalachian Mtns. in Virginia and West Virginia. In VA, traps were placed on a quasi 2 km grid and in WV the traps were in a qualsi 3 kim grid. In certain locations (where isolated colonies were thought to exist based upon previous years trapping data) traps were put at much higher densities. These data exhibit a very strong trend - counts are very high to the northeast and low (mostly zero) in the southwest. This is because the trapping grid was located on the advancing front of the expanding range of this species. Data are formated as easting, northing, males/trap. Coordinates are in UTM values.

title: Counts of oribatid mites in sphagnum mosses

description: In June 1989, 70 cores of Sphagnum moss (5 cm in diameter and 7 cm deep) were extracted from a 10 x 2.5 m sampling area in a floating moss and peat blanket extending from the forest border into the lake; the blanket is 10 m broad on the average. Sampling was stratified by types of substrate, with the number of cores in each subsample proportional to the surface area of its stratum. One of the aims of the sampling was to study the spatial distribution of the oribatid community in the mosses, and to verify whether this structure could be related to that of environmental variables.. Within the sampling area, mosses have not been disturbed during recent years, so we considered their spatial pattern to be natural. This data set contains 3 files (below). Data on a line are separated by tabs. 1) Oribatida: 35 species (rows) x 70 sites (columns). 2) Coord.xy: 70 sites (rows) x 2 coordinates, in m, in Cartesian plane (columns). 3) Environ: 70 sites (rows) x 5 environmental variables (columns). The environmental variables were: substratum (seven unordered qualitative classes: four species of Sphagnum, ligneous litter, bare peat, interface bewteen Sphagnum species); coverage density of the shrub cover (three semi-quantitative classes); morphology of the substratum (two qualitative classes: blanket or hummock); density of the substratum in g/l of dry uncompressed matter (quantitative); and water content in percent (quantitative).

title: Global Distribution of Root Profiles in Terrestrial Ecosystems

description: A database of vertical root profiles for global terrestrial ecosystems was assembled from the primary literature in order to characterize the belowground structure of global vegetation types and to study relationships of belowground vegetation structure with climate, soil characteristics, and aboveground vegetation structure. Variables used to characterize belowground vegetation structure include the depth above which 50 percent of all roots are located and the depth above which 95 percent of all roots are located in the profile. For each root profile, information recorded includes latitude and longitude, elevation, soil texture, depth of organic horizons, type of roots measured (e.g., fine or total, live or dead), sampling methods, units of measurements (root mass, length, number, surface area), and sampling depth. Some profiles lack information on one or more of these variables. Also recorded are presence and dominance of plant life forms (including succulents, forbs, grasses, semi-shrubs, shrubs, and four categories of trees: needle-leaved vs. broadleaved, evergreen vs. deciduous) and whether the vegetation was relatively natural or altered by humans (e.g., forest plantations and pastures). The database also includes data on mean annual precipitation and the seasonal distribution of precipitation. Data sets that are related to this root profile data set include root nutrient concentrations (for approximately 372 site-pit-depths from 56 papers in Gordon and Jackson 2000) and root turnover rates (data for approximately 188 sites from 152 papers that were used to estimate root turnover rates for 341 site-vegetation combinations in Gill and Jackson 2000). The three recent papers include most of the data contained in the initial root data set; however, some observations may have been excluded because of more stringent selection criteria. Many of the source papers provided data for all three of the rooting data sets and users are encouraged to review all three data sets. The Oak Ridge National Laboratory (ORNL) Distributed Active Archive Center (DAAC) for Biogeochemistry Dynamics organized and formatted these data for long-term archive. The archived data are contained in two files: (1) The ecosystem root profiles file, containing estimated 50 percent rooting depths (D50) and 95 percent rooting depths (D95) plus information on sampling methods, vegetation, climate, and soil, and (2) a file containing the references to file (1). These files were obtained from H. Jochen Schenk, Department of Biological Science, California State University Fullerton, California, in February 2003. The data were placed into a spreadsheet format and stored as an ASCII comma-separated (.csv) file. Missing values are represented by -999.

title: Global Distribution of Root Turnover in Terrestrial Ecosystems

description: Estimates of root turnover rates were calculated from measurements of live root standing crop and belowground net primary production (BNPP) compiled from the primary literature. Vegetation characteristics, soil properties, and climate conditions were associated with turnover rates to examine patterns and controls for biomes worldwide (Gill and Jackson 2000).

title: PISCO: Physical Oceanography: bottom-mounted ADCP data: Jalama Beach Campground, California, USA (JAL)

description: This metadata record describes bottom-mounted ADCP data collected at Jalama Beach Campground, California, USA, by PISCO. Measurements were collected using an RDI 600 kHz Workhorse Sentinel ADCP beginning 2001-02-15. The instrument depth was 015 meters, in an overall water depth of 15 meters (both relative to Mean Sea Level, MSL). The instrument was programmed with a sampling interval of 2.0 minutes and a vertical resolution of 1 meter.
