Biogeographic distribution of Scottnema lindsayae in Victoria Land, Antarctica. NP = not published. NA = specific coordinates not available within the named locale identified above. For references to “this paper”, the year collected refers to the year at the beginning of the austral summer in which samples were collected at 0-10 cm depth unless otherwise indicated. For abundance, ‘Present’ indicates no abundance information available, Low = >0 to 20 nematodes per kg dry soil, M-low = 21 to 200 nematodes per kg dry soil, Medium = 201 to 600 nematodes per kg dry soil, M-high = 601 to 1000 nematodes per kg dry soil, High = 1001 to 2000 nematodes per kg dry soil, V-high = >2000 nematodes per kg dry soil, n = number of samples and % = percentage of samples in which Scottnema lindsayae occurred. AThere may have been a typographical error in the original publication reporting this latitude/longitude. *Geographic coordinates associated with the recognized Antarctic place name for a general feature as listed by the USGS Advisory Committee on Antarctic Names (http://geonames.usgs.gov/antarctic/) and updated by the Polar Geospatial Center (http://www.pgc.umn.edu).
