实验室条件下研究了起始食物浓度和温度对舞行波豆虫(Bodo saltans)种群生长的影响.在起始食物浓度分别为2.10×106,2.80×106,4.20×106,6.40×106mL-1的条件下,B.saltans种群生长率分别为0.116 6,0.137 6,0.120 2,0.112 8 h-1,相应的世代时间分别为5.90,5.00,5.80,6.10 h.温度对B.saltans种群生长有显著影响,当培养温度分别为10,20,30℃时,B.saltans种群生长率分别为0.050 0,0.124 6,0.120 3 h-1,相应的世代时间分别为13.86,5.60,5.80 h.温度从10℃升高到20℃时,B.saltans的种群生长率升高2.49倍,相应世代时间减少8.3 h;而当培养温度从20℃升高到30℃时种群生长率和世代时间变化不大.与个体大小相近的其他异养鞭毛虫类群(如领鞭毛类)相比,波豆虫具有种群增长迅速、世代时间短的特点.
