| 中文摘要 | The vertical distribution of dominant genera of bacterivorous nematodes to 150-cm depth in an aquic brown soil was compared after 14 years of four contrasting land uses, i.e., cropland-rice (CR), cropland-maize (CM), abandoned cropland (AC), and woodland (WL). The study was conducted at the Shenyang Experimental Station of Ecology, a Chinese Ecosystem Research Network (CERN) site in Northeast China. Data were analyzed using two-way analysis of variance with land use and depth as independent variables. More than 70% of Chiloplacus, Fucephalobus, and Monhystera spp. were present in the uppermost soil layer (0 to 5 cm) in the CR treatment. In contrast, Chiloplacus and Prismatolahnus spp. were distributed down to 100-cm depth in the AC and CM treatments, respectively. Differences in numbers of Acrobeles, Acrobeloides, Cephalobus, Chiloplacus, Eucephalobus, Monhystera, Plectus, and Prismatolaimus were found among land uses and at various depths. Soil C and N were correlated positively with numbers of Monhystera and Plectus in the CR treatment, Acrobeloides in the CM treatment, and Acrobeles and Acrobeloides in the AC treatment. Soil pH was correlated negatively with Monhystera, Plectus (CR), and Acrobeloides (CM, AC). The relationship of pH with Acrobeles depended on land use: positive in the WL treatment and negative in the AC treatment. Our results suggested that Cephalobus and Prismatolaimus in the CR treatment, and Chiloplacus and Prismatolaimus in the WL treatment, were insensitive to soil properties measured. Differences in vertical distribution should be considered when studying dominant bacterivorous nematode genera among land uses. |
