Table 4.
Biogeographic distribution of Panagrolaimus davidi in Victoria Land, Antarctica. NP = not published. NA = not available. For references to “this paper”, the year collected refers to the year at the beginning of the austral summer in which samples were collected. For abundance, M-low = 21 to 200 nematodes per kg dry soil, Medium = 201 to 600 nematodes per kg dry soil, n = number of samples and % = percentage of samples in which Panagrolaimus occurred.
