The nematode community distribution

The study found that nematode composition differed significantly between the upper and deeper layers of sediment but not among the deeper layers. Nematode density showed spatial variability across layers, with higher values in the upper layer. Nematode diversity decreased with increasing depth. Non–selective deposit feeders (1B) were dominated in the surface layers, while the predator–omnivores feeders (2B) was numerous in the deeper layers

This study aims to investigate how nematodes’ communities variables such as diversity, sex and feeding structure alter in different 5 layers of sediment deep profile of the river bed. Our studies found for the first time that nematodes’ communities not only stay on 10 cm first layers but they can contribute until 50 cm deep in the sediment profile of the river bed.

A survey was carried out to study the distribution of plant parasitic nematodes associated with fruit crops of Bhubaneswar- The capital of state Odisha, India. Around 240 soil samples were collected from the rhizosphere of fruit crops; cashew nut, guava, papaya and lime across the different places of Bhubaneswar. Nematodes were isolated by Cobb’s sieving and decanting method followed by modified Baermann’s funnel technique. Communities of plant parasitic nematodes were analysed.

A survey was conducted to explore the existence of plant parasitic nematodes associated with millet crops in Tiruvannamalai District. In this study, nine genera of plant-parasitic nematodes were recognized. The analysis of nematode communities revealed that the Tylenchorynchus sp. was the most frequently occurring nematode having an absolute frequency of 46.6% followed by Helicotylenchus sp. (38.8%) and Meloidogyne sp. (25.9%).

As mentioned above, the purpose of this research was to: (i) to survey of nematode assemblages in the Ba Lai river (from estuary to upstream) by assessing their composition, density and diversity and also (ii) determine effects of Ba Lai dam on the distribution of nematode communities.

The highest numbers of nematodes with a percentage ranging from 76.4% in Cung Hau to 77% in Ham Luong estuaries. There were 92 genera (71 genera in Ham Luong and 62 genera in Cung Hau) of nematodes recorded in both estuaries. The mean nematode densities varied between 90 ± 31 - 1524 ± 269 ind.10 cm² and 105 ± 79 - 1120 ± 534 ind.10 cm² in Ham Luong and Cung Hau estuary, respectively.

This paper showed result of the studying composition and abundance of meiofaunal communities from Cung Hau estuary and Ham Luong estuary, with special focus on the nematode communities. The results of this study will illustrate the overall patterns in the species composition, density and diversity of meiofaunal communities in two estuaries Ham Luong and Cung Hau of Me Kong Delta in the Southern of Vietnam.
