Item Identification

Title: Estimated seabird species richness
Short Name: Estimated seabird species richness
Status: Completed

Estimated seabird species richness from spatial statistical models developed by the NOAA Biogeography Branch. We operationally define seabirds as all avian species regularly sighted over marine waters. Given this definition, most species included in this chapter belong to the following taxonomic orders: Charadriiformes (gulls, terns, auks, phalaropes), Pelecaniformes (gannets, pelicans, and cormorants), and Procellariiformes (shearwaters, fulmars, petrels). Species richness is defined as the number of species present. Our best estaimte of species richness comes from the median of upper and lower bounds on predicted species richness at each location, obtained by summing minimum and maximum number of species that could have been present over all species and groups, treating each species or group as present if its predicted relative abundance was above a threshold. | Description Source: NOAA
