    Mass loss datafile and nitrogen concentration data

    The primary objective of this study is to examine the control that substrate quality and climate have on patterns of long-term decomposition and nitrogen accumulation in above- and below-ground fine litter. Of particular interest will be to examine the degree these two factors control the formation of stable organic matter and nitrogen after extensive decay. These data sets are part of : (LIDET) Harmon, M. 2005. LTER Intersite Fine Litter Decomposition Experiment (LIDET): Long-Term Ecological Research.Corvallis, OR: Forest Science Data Bank: TD023. [Database].

    Masting dynamics data set

    This group compiled an extensive data base of time series for masting species with associated climatic data. Individual seed production in 59 populations of plants from 24 species spanning a large range of annual variablilty, from species exhibiting strong masting to others with little annual variability in seed production was explored.

    Molecular sequence data for emydid turtles

    The data consists of molecular sequences (cytochrome b, ND4, and R35) the final processing of which was done here at NCEAS. As is required for publication in most journals, the sequences have been depsoited in GENBANK. HTML links to GENBANK and preliminary list of accession numbers is provided.

    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.
