“…Aphelenchoides baguei Maslen (1979) Dimension Refer Table 3 Description Remarks The morphological details and dimensions of the present specimen conform well with those described by Maslen (1979) though some variations are found in body and tail lengths which may be due to intraspecific variations. Aphelenchoides confusus Thorne and Malek (1968) Dimension Refer Remarks The morphological characteristics and dimensions of the present species conform well with those described by Thorne and Malek (1968) though some variations are found in the length of body and tail which may be due to intraspecific variations.…”

Study of Aphelenchoides nematodes from different localities of Manipur were conducted for their documentation. During the study eight known and a new species were identified. Aphelenchoides aerialis sp. nov. differed from all other species of Aphelenchoides in having a tail without bifurcation and strong ventral mucro with single ventrosublateral caudal papillae in male. The known species along with the new species are described in the present study.

“…An outstanding feature of high latitude nematode faunas is their frequently high species richness (e,g. Mulvey, 1963;Kuzmin, 1973;Procter, 1977Procter, , 1979Spaull, 1973a;Maslen, 1979) compared with mid-latitude, and low latitude faunas (e.g. Nielsen, 1949;Banage & Visser, 1967;Willard, Fisher & Petrovich, 1973;Wasilewska, 1970;Yeates, 1967Yeates, , 1970Yeates, , 1972Yeates, , 1973.…”

“…or Teratocephalus spp. (mean stoma widths of the nematodes are c. 7, 5 and 3 μm, respectively [2,10]), it is not surprising that it was more attracted to algae and fungi than the other two nematodes: with the exception of the bacterium B1, algal and fungal cells were larger than the bacteria offered to nematodes.…”

“…Not only are they abundant, with up to 10 6 individuals present per m 2 of soils in the Maritime Antarctic [11], but they also play important ecological roles in these soils by acting as consumers, typically of bacterial prey, and also as predators of other nematodes, rotifers and protozoa [21]. Furthermore, nematodes are the top predators in what are thought to be the simplest soil food webs encountered on Earth, those occurring in the McMurdo Dry Valleys of Continental Antarctica [7].…”

“…Furthermore, nematodes are the top predators in what are thought to be the simplest soil food webs encountered on Earth, those occurring in the McMurdo Dry Valleys of Continental Antarctica [7]. Previous studies have concentrated on Antarctic nematode taxonomy, ecophysiology and biogeography [2,7,10,11,15,26]. However, despite their potentially large ecological influence, little is known of the feeding preferences of Antarctic soil nematodes [11].…”

We tested the preferences of three nematode taxa, Geomonhystera villosa, Plectus spp. and Teratocephalus spp., extracted from moss at Signy Island in the Maritime Antarctic, for two microalgae, three microfungi and six heterotrophic bacteria, each also from soils at Signy Island.Choice test experiments on water agar medium, in which nematodes were enumerated in wells containing microbes at 24 and 48 h, indicated that there were differing preferences between nematodes for distinct prey. G. villosa was significantly attracted to the alga Chlorella cf. minutissima and the fungus Mortierella hyalina, and was more attracted to all algae and fungi than either of the other two nematodes. Both G. villosa and Teratocephalus spp. were attracted to an actinobacterium. Plectus spp.were significantly attracted to the alga Stichococcus bacillaris and bacteria with close taxonomic affinities to Arthrobacter, Pseudomonas and Polaromonas. Experiments using 0.5 µm diameter fluorescent beads indicated significantly increased ingestion by nematodes in the presence of each of these microbes compared with controls, except by Plectus spp. in the presence of S. bacillaris. We conclude that complex trophic interactions may occur in apparently simple Antarctic soil food webs.
