    Puma genetic data: Southwestern USA

    Data consist of genotypes and geographic locations of 540 free-ranging pumas (Puma concolor) sampled throughout the states of Utah, Colorado, Arizona, and New Mexico. All pumas were legally killed by hunters between 1999 and 2002. Pumas were genotyped at 16 microsatellite loci, with known relatives excluded.

    Ranking and mapping the impact of human activities on global ocean ecosystems

    Conservation prioritization and spatially explicit management of the oceans require high-resolution maps of where human impacts to marine ecosystems occur, yet few such maps exist. Here we synthesize global data on 17 threats and 14 marine ecosystems to produce a global, 1km2 resolution map of human impacts specific to each marine ecosystem. We found that none of the ocean is unaffected by humans but that a relatively small fraction is heavily impacted, and that results vary greatly by region and ecosystem type.

    Sea-viewing Wide Field-of-view Sensor (SeaWiFS)

    Subtle changes in ocean color signify various types and quantities of marine phytoplankton (microscopic marine plants), the knowledge of which has both scientific and practical applications. It became apparent to the oceanographic community that because of the dynamic nature of the world's oceans and climate, and the importance of the ocean's role in global change, a follow-on sensor to the Coastal Zone Color Scanner (CZCS) should be flown.

    Serengeti ecosystem

    The Serengeti ecosystem exemplifies a number of general features of terrestrial food web dynamics and can therefore be viewed as a model system for studying a complex interplay of basic ecological principles.

    Spatial locations and size measurements of Ambrosia dumosa in Joshua Tree National Park

    This data set contains spatial locations and size measurements of Ambrosia dumosa plants sampled in a 1-ha plot in Joshua Tree National Park in 1984.

    U.S. National Park Service kelp monitoring database

    NCEAS Project, "7600: Halpern: Implications for reserve design (Hosted by NCEAS)", and a paper titled, "Supporting Online Material for Strong Top-down control in Southern California Kelp Forest Ecosystems" used this MS Access database. The U.S. National Park Service has been conducting annual surveys of algal, invertebrate, and fish abundances at 16 different kelp forest sites around the five islands in the Channel Islands National Park since 1982 as part of the Kelp Forest Monitoring Program (KFMP).

    Updated zooplankton data for 7/8 Dorset lakes in 1993-96

    Updated zooplankton data for 7/8 Dorset lakes in 1993-96. Pelagic crustacean zooplankton were sampled in each lake on a monthly basis. The data is in post93zoodata.csv.

    Zooplankton for all 8 Dorset lakes

    Zooplankton for all 8 Dorset lakes (last updated version of lakezoo.txt: 21 January 1997) Pelagic crustacean zooplankton were sampled in each lake on a monthly basis (fortnightly in harp and plastic) from 1978 to 1992 (1978 to 1995 in harp and plastic). These data are in tab-delimited ASCII format, without column headings, in lakezoo2.txt. Samples with missing biomass estimates in the years 1978 to 1981 were counted using a different protocool than the rest of the samples.

    Zooplankton for Middle and Hannah Lakes (Sudbury)

    Zooplankton data from the two Sudbury lakes (Middle and Hannah). Pelagic crustacean zooplankton were sampled in each lake on a monthly basis from 1973 to 1992. These data are in tab-delimited ASCII format, without column headings, in MEHHZOO.TXT. N.B. Samples with missing biomass estimates in the years 1973 to 1984 were counted using a different protocool than the rest of the samples.
