Fields in a concentrated area of soybean production in South Carolina were chosen for soil sampling to determine the distribution of plant-parasitic nematodes. Five hundred sampling sites were distributed over 19 counties according to county soybean acreage. Helicotylenchus and Scutellonema were identified most frequently from soil samples; together, these genera occurred in over 70% of the sam...

The helical cytokine interleukin-6 (IL-6) assembles a multiprotein receptor complex. The starting event in the activation of intracellular signaling is the binding of the IL-6/IL-6R alpha subcomplex to two gp130 chains. The homodimerization of gp130 is triggered by two distinct and independent regions of IL-6 called sites 2 and 3. Several IL-6 antagonists have been obtained that affect signalin...

the distribution of macroinvertebrate communities from 5 sampling sites of the tajan river were used to examine the relationship among physiochemical parameters with macroinvertebrate communities and also to assess ecological classification system as a tool for the management and conservation purposes. the amount of variation explained in macroinvertebrate taxa composition is within values repo...

Based upon ecological data provided by a 6-year study of native species assemblage structure and function in near-pristine Limahuli Stream (Kauai), The Hawaii Stream Index of Biological Integrity (HS-IBI) incorporates 11 metrics covering five ecological categories (taxonomic richness, sensitive species, reproductive capacity, trophic-habitat capacity, and tolerance capacity). The HS-IBI was sho...
