Effects of fertilizer and weed species richness on soil nematode community in a microcosm field experiment
نویسندگان
چکیده
Both fertilizer and plant species richness may affect the soil nematode community. However, influence of weed interaction is unclear. Nematode abundance biodiversity in wheat plots treated with nitrogen, phosphate potassium addition (0, 1, 2 4 levels) were investigated a long-term microcosm experiment established 2010 at Kaifeng, China. The results demonstrated that treatment increased total nematode, bacterivores, parasites whereas it decreased genera number, Shannon—Wiener diversity index (H′), Margalef (SR), maturity (ΣMI), structure (SI), degraded In contrast, these ecological indices enhanced Principal component analysis (PCA) indicated fertilizer’s effect was more significant than richness. Redundancy (RDA) affected mainly through increasing available phosphorus by 4.71 times ammonium nitrogen content 74.03%; enhancing moisture 2.07%. Our suggest relieve negative on

Species richness effects on grassland recovery from drought depend on community productivity in a multisite experiment.
Biodiversity can buffer ecosystem functioning against extreme climatic events, but few experiments have explicitly tested this. Here, we present the first multisite biodiversity × drought manipulation experiment to examine drought resistance and recovery at five temperate and Mediterranean grassland sites. Aboveground biomass production declined by 30% due to experimental drought (standardised ...
متن کاملMetacommunity influences on community richness at multiple spatial scales: a microcosm experiment.
Large-scale processes are known to be important for patterns of species richness, yet the ways in which local and larger scale processes interact is not clear. I used metacommunities consisting of five interconnected microbial aquatic communities to examine the manner in which processes at different scales affect local and metacommunity richness. Specifically, I manipulated the potential disper...

abstract reception environment has considerable effects on accepting a translation. as the expectations of a target culture and its values and needs change throughout history, its criteria for accepting a translation or rejecting it will change accordingly (gentzler, 2001). the expectations of iran, as the reception environment in the present study, have changed after the islamic revolution. i...
Effects of N fertilizer and a bioherbicide on Egyptian broomrape (Orobanche aegyptiaca) in a tomato field
This study aimed to investigate the effects of nitrogen fertilizer and a bioherbicide on Egyptian broomrape in a tomato research field at College of Agriculture, Shiraz University, Shiraz, Iran in 2014. Treatments consisted of several levels of nitrate ammonium including 0, 100, 200 and 300 kg ha-1 and a biofertilizer as the first factor and how to use the bioherbicide including soak...
متن کاملcritical period effects in foreign language learning:the influence of maturational state on the acquisition of reading,writing, and grammar in english as a foreign language
since the 1960s the age effects on learning both first and second language have been explored by many linguists and applied linguists (e.g lennerberg, 1967; schachter, 1996; long, 1990) and the existence of critical period for language acquisition was found to be a common ground of all these studies. in spite of some common findings, some issues about the impacts of age on acquiring a second or...
