Dy also indicated that some resistant materials can suppress the development of nematodes. At 15 days soon after inoculation, white females have been observed on susceptible materials, comparing with only J3 or J4 have been observed on resistant varieties. Additionally, some supplies can inhibit the invasion of nematodes. The resistance mechanism requirements further investigation and these resistant components are valuable for breeding in future. IMPACTS OF SURFACE MINING RESTORATION EFFORTS ON SOIL-DWELLING NEMATODE COMMUNITIES Inside the APPALACHIAN Region. Smith, Haley S. and E.C. Bernard.

Coal will be the largest component of energy expected to power electrical plants. Within the United states, about 62 of coal is mined using surface mining, a technique that destroys native ecosystems. Post-mining reclamation is needed to decrease long-term environmental impacts connected with surface mining. Traditional restoration of post-mining web-sites within the southeastern U.S. consists of strategies that discourage above and below-ground succession of native flora and fauna communities. Recent advances in mining restoration tactics proposed by the Appalachian Regional Reforestation Initiative (ARRI) have improved reclamation of post-mining websites above-ground by growing native tree abundance and development rate. The below-ground component of these reclaimed regions remains undescribed. Diverse soil nematode faunas have been shown to enhance nitrogen uptake in hardwood seedlings, which may perhaps play a important part in these nitrogen-limited, early successional systems. We addressed how conventional restoration solutions used following the passage on the Surface Mining Control and Reclamation Act (SMCRA) approved by the Office of Surface Mining, also as ARRI’s Forestry Reclamation Method (FRA), influence below-ground nematode communities. Soils were collected from mining restoration web-sites applying each postSMCRA and FRA approaches from three age groups: 0-3 years since reclamation, 4-8 years given that reclamation, and 9 + years due to the fact reclamation, at the same time as unmined forest soils. Nematodes were extracted from these soils and identified to morphospecies. Soil pH was also determined. In addition, the effect of those nematode communities on plant survival and nutrient uptake in mined soils was determined by seedling biomass of plants grown in mining soils with nematode communities of varying diversity. Carbon and nitrogen ratios of those seedlings were measured to estimate the value of nematode communities as bioremediators. Nematode biodiversity increased with soil age, with forest soils obtaining the highest biodiversity. Bacterial feeders have been the dominant feeding group. Plectid diversity was greater within the oldest age groups of each SMCRA and FRA soils than in younger soils. Soil restoration age, not restoration approach or nematode neighborhood, was the main driver of seedling biomass.
