    NPP multi-biome: NPP and driver data for ecosystem model-data intercomparison

    The Ecosystem Model-Data Intercomparison (EMDI), an on-going activity whose first workshop was held in Durham, New Hampshire, USA, in December 1999, provides the first opportunity for a wide range of global carbon cycle models to be compared with measured net primary productivity (NPP). The second EMDI workshop was held in April 2001 at the National Center for Ecological Analysis and Synthesis (NCEAS), Santa Barbara, California, U.S.A.

    Plant reproductive susceptibility to habitat fragmentation meta-analysis

    List of 89 plant species selected for the meta-analysis. For each species we show the botanical family, the value of effect size (Hedge's d) and its variance (Vd), the compatibility system (CS), pollination specialization (PS), life form (LF), habitat type, geographic region and the source publication where information was obtained. SI: self-incompatible, SC: self-compatible, S: specialist, G: generalist, T: tree, Sh: shrub, V: vine, H: herb, Hp: hemi-parasite, ep: epiphyte.

    Predator prey allometry in fishes

    Predator-size prey-size relationships for piscivorous fishes. We use these data to compare cannibal to non-canibal prey, predator-size prey-size relationships among Northwest Atlantic fishes (part of these data are available at Ecological Archives E086-135; http://esapubs.org/archive/ecol/E086/135/), western Pacific large pelagics and for 14 populations of striped bass.

    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.

    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).
