    Coho salmon online data from Myers' stock recruitment database

    The Coho Salmon data is part of Ranson Myers Stock Recruitment Database site. The site consists of maps, plots, and numerical data relating to over 600 fish populations (over 100 species) from all over the world. Approximately 100 new populations are added per year. The purpose of this site is to compile all population dynamics data on fish in the world, so that synthetic analyses will lead to enhanced conservation and improved fisheries management.

    Determining pan-tropical patterns of liana distributions from regional datasets

    This dataset contains information on the abundance, basal area, and species identity for more than 80,000 lianas from tropical forests located in Mexico, Central and South America, Africa, and Asia. We have compiled this dataset to determine the distribution of lianas (abundance, biomass, and diversity) across large geographic regions and abiotic gradients throughout the tropics.

    Digital library of management laws: California current large marine ecosystem

    I am creating this library as part of my dissertation research project at U.C. Santa Barbara. I am using a digital integration technology (DIGIN®) to create this library, which has the functionality of a database but the capacity of a library. The international agreements and treaties, as well as the national (United States and Mexico), state (Washington, Oregon, California and Baja), and local laws and regulations are included in this library to represent governmental level management within the scope of the California Current Large Marine Ecosystem.

    Evolutionary significant units (ESU) table

    This table was shared in conjunction with a working group project to assess the usefulness of algorithms and quantitative approaches to measuring biodiversity in terms of 'taxonomic distinctiveness' or 'independent evolutionary units'. The group evaluated whether and how phylogenetic information can be used to measure species value. Specifically, they analyzied the effects of sample size, topology, branch lengths and model of evolutionary change on various quantitative measures of phylogenetic diversity.

    Foraging trait variation in Ambystoma maculatum

    Predator-prey interactions often vary markedly across natural landscapes. One explanation for this variation is local genetic differentiation of prey traits due to selection from predators. Here, I evaluated the relative contributions of selection from a gape-limited predator (Ambystoma opacum) and spatial location within a larger landscape to explanations of variation in foraging, growth, and survival in 10 populations of temporary pond breeding salamander larvae (Ambystoma maculatum).

    Geographic range occupancy of North American birds

    Although the geographic range is a fundamental unit of analysis for many macroecological and biogeographical studies, as a representation of the spatial distribution of individuals it is clearly a scale-dependent abstraction. As any amateur naturalist realizes, a species is not guaranteed to be present at every point within the range delimited by a field guide. Geographically extensive survey data such as the North American Breeding Bird Survey (BBS) allow the characterization of distribution patterns within the geographic range.

    Global analysis of nitrogen and phosphorus limitation

    The cycles of the key nutrient elements nitrogen (N) and phosphorus (P) have been massively altered by anthropogenic activities. Thus, it is essential to understand how photosynthetic production across diverse ecosystems is, or is not, limited by N and P. Via a large-scale meta-analysis of experimental enrichments, we show that P limitation is equally strong across these major habitats and that N and P limitation are equivalent within both terrestrial and freshwater systems.

    Hurricane related demography of Ardisia escallonioides (FL)

    Demographic rates of a subtropical undestory shrub in seven different states of canopy openness and habitat transition estimates for states of canopy openness in subtropical hardwood hammocks of extreme southern Florida. Demographic rates were estimated from empirical data at 4 sites after Hurricane Andrew, a category 5 hurricane (Aug 24, 1992). Habitat dynamics were estimated from the historical record combined with empirical data on the rate canopy closure (from fisheye photographs).

    Incidence of the rust Triphragmium ulmariae on Filipendula ulmaria in the Skeppsvik archipelago, Sweden

    The data set provides information on the incidence and severity of a rust fungus Triphragmium ulmariae occurring in populations of the herbaceous perennial Filipendula ulmaria growing on a range of islands in the Skeppsvik archipelago, northern Sweden. These data, together with information on the size of individual host populations, is being used to monitor temporal and spatial dynamics in a natural plant pathogen - host metapopulation system.
