Brief Description (Abstract):

Investigations relating to ecology of terrestrial invertebrate fauna of Antarctica are mainly confined to the Sub-Antarctica and maritime zones. The effects of some physico-chemical soil factors on the distribution of soil nematode fauna have not been attempted so far in Schirmacher Oasis of Antarctic Continental zone. Only ten species, representing six genera of nematodes, have so far been recorded from the Continental Antarctic zone (Maslen, 1979). Five genera of nematodes viz., Tylenchorhynchus, Drylaimellus, Aporcelaimellus, Dorylaimoides, and Paramylonchulus were recorded for the first time from this area. Altogether 30 stations among 15 study sites were chosen for sampling during the study period from 3.1.90 to 30.2.90.

Status: Completed

Purpose: The results presented in this investigation were based on sample survey of 30 stations from 15 sampling sites of Schirmacher Oasis area of the Antarctic continent. The nematode fauna, encountered in this study, belonged to 4 genera of the families Tylenchorhyncludae, Belondiridae, Leptonchidae and Mylonchulidae. Tylenchorhynchus sp. was most dominant soil fauna in the present study. It is interesting to note that so far only six genera and ten species of nematodes have been reported from the Continental Zones by Maslen (1979). These included Plectus, Monhystera, Panagrolaimus, Scottnema, Eudorylaimus and Mesodorylaimus but all the four genera (viz. Drylaimellus, Dorylaimoides, Tylenchorhynchus and Paramylonchulus) obtained in the present study have not been reported so far from this continent, therefore it seems to be the additions to the nematode fauna in the Antarctic Continental Zone.
