Abstract EN
Nematodes are the most diverse and highly significant group of soil-inhabiting microorganisms that play a vital role in organic material decomposition and nutrient recycling.
Diverse geographical locations and environmental gradients show a significant impact on the diversity of nematodes.
Present study aims to assess the effects of ecological (altitude, temperature, moisture) and edaphic (soil pH, nutrients, soil patches) factors on the soil nematode diversity and structure at five dif- ferent landscape patches (forests, apple orchards, rice fields, pastures, and alpine zone) from ten different sites of Kashmir valley (India).
Differences in the altitudinal gradients results in the shift of generic nema- tode population.
Among the soil patches, highest nematode diversity was observed in forest soil and least in alpine soil; however, bacteriovorous nematodes dominated all the soil patches.
The temperature and moisture have a significant effect on nematode diversity, the highest nematode trophic levels were observed above 21C temperature, and 30% moisture.
Nematode abundance decreased from alkaline to acidic pH of the soil.
Soil nutrients such as, nitrogen (N) and phosphorus (P) have shown a detrimental effect in nematode richness at each site, where nematode diversity and richness of genera were higher at abundant soil N and P but decreased at low soil nutrients.
Ecological indices like diversity index (DI), Shannon-Wiener Index (H’), enrichment index (EI), and maturity Index (MI) values demonstrated forest soil more favourable for nematodes and high soil health status than other soil patches.
This study suggested that these indices may be helpful as soil monitoring tools and assessing ecosystem sustainabil- ity and biodiversity.
