{"thcode":23,"term":{"code":31,"name":"Biological Occurrence","parent":26,"scope":"Biological Occurrence data identify different taxa together with the times and locations in which these particular organisms live. Distributions for these data subject types record observations of identifiable taxa at known times and places on the basis of captured samples, imagery, genetic testing, or other methods. Distributions also include single-taxon modeling approaches such as habitat suitability index models or essential fish habitat models; interpretations based on empirical correlations; population change models; connectivity estimates; or evaluations of migratory pathways and spawning grounds. Assessment types include spatially applicable indices for identifying and valuing regional taxa; classifications of species (for example, as harvested, protected, or invasive) as a function of location and time; evaluations of organism condition; assessments of stressor or disturbance effects on taxa, assemblages and communities; evaluations of ecological value of species (for example, keystone species, nonredundant species); taxon-based ecological services models; and place-based indices of susceptibility and vulnerability to disturbance. Predictions include evaluations of future impacts, distributions, and ecological or economic effects due to single or multiple stressors and other projected changes, as well as scenario-testing models of taxon losses\/gains under different management options, usually combined with projections of related ecological or economic effects."},"uf":[],"bt":[{"code":26,"name":"Living Resources","parent":6,"scope":"Includes aspects of coastal and marine biota that are of particular importance to ecology or to human uses.
