| 采取捕食者-猎物间捕食效应研究方法,研究了黑暗条件下缢蛏对牟氏角毛藻、青岛大扁藻的滤食效应。结果表明,缢蛏滤食牟氏角毛藻和青岛大扁藻的功能反应均属Holling-Ⅱ型,拟合的圆盘方程分别为Na=0.981*N0/（1+0.00039*N0）和Na=0.7949*N0/（1+0.00636*N0）;缢蛏自身密度对滤食牟氏角毛藻、青岛大扁藻功能反应影响的数学模型分别为E=0.985P-1.0256和E=0.778P-1.1819;缢蛏自身密度与牟氏角毛藻、青岛大扁藻藻浓度间的联合反应方程分别为Na=0.9663*P-0.0256*N0/（1+0.00039*N0）和Na=0.6182*P-0.1819*N0/（1+0.00636*N0）分析了缢蛏的滤藻速率、滤藻功能反应类型及滤藻效应特征。 |

| Abstract: |
| The effect of filter-feeding in dark by Sinonovacula constricta on Chaeroeeros moelleri and Platymonas subcordiformis was studied. The result show that the pattern of functional response in S. constricta to C. moelleri and P. subcordiformis is of Holling-II type, the fitted Holling’s disc equations are Na=0.981*N0/(1+0.00039*N0)and Na=0.7949*N0/(1+0.00636*N0), respectively, while that of density to C. moelleri and P. subcordiformis are E=0.985P-1.0256 and E=0.778P-1.1819. The associated response equations between the density of S. constricta and C. moelleri, and that of S. constricta and P. subcordiformis are Na=0.9663*P-0.0256*N0/(1+0.00039*N0) and Na=0.6182*P-0.1819*N0/(1+0.00636*N0), respectively. In addition, the filter-feeding rate, the type of functional reaction and the effect of S. constricta on algae were studied. |
