鱼类对湖泊中的浮游动物群落具有主要的结构影响(Hrbacek等人,1961年;布鲁克斯和多德森,1965年),可能级联到较低的营养水平和化学环境(卡彭特等人,1985; Carpenter和Kitchman,1993)。从封闭实验中可获得充分的证据(例如,Christoffersen等人,1993年),全湖实验(例如,夏皮罗等人,1975; Benndorf,1987; Gulati et al.,1990; Carpenter和Kitchell,1993)和经验分析(Jeppesen等人,1990年、1997年)。最近,已经变得明显的是,0+鱼类可能在浮游动物种群动态中起关键作用(Cryer等人,1986;米尔斯等人,1987),并且一些研究表明,鱼苗是浮游动物仲夏减少的原因(Luecke等人,1990; Jeppesen等人,1997年),这是一种现象,往往是由于密度增加不可食用的浮游植物,如蓝藻(例如,德贝尔纳迪和Guisanni,1990年)。全湖(S~ mdergaard等人,1997)和围隔(He和Wright,1992)实验支持0+鱼的结构作用。鱼类自上而下控制浮游动物的重要性是如何沿着营养梯度变化的,这一点引起了广泛的争论。McQueen等人,(1986)提出,在贫营养湖泊中,食动物性鱼类的级联效应比在富营养湖泊中更强,但越来越多的文献认为,在经典意义上,鱼类的级联效应在富营养和富营养湖泊的食物网中更大
Fish have a major structuring impact on the zooplankton communities in lakes (Hrbacek et ai., 1961; Brooks and Dodson, 1965) that may cascade to the lower trophic levels and chemical environment (Carpenter et aI., 1985; Carpenter and Kitchell, 1993). Ample evidence is available from enclosure experiments (eg, Christoffersen et ai., 1993), whole-lake experiments (eg, Shapiro et aI., 1975; Benndorf, 1987; Gulati et aI., 1990; Carpenter and Kitchell, 1993), and empirical analyses (Jeppesen et ai., 1990, 1997). More recently, it has become evident that 0+ fish may play a key role in zooplankton population dynamics (Cryer et aI., 1986; Mills et aI., 1987), and some studies suggest that fish larvae are responsible for the midsummer decline in zooplankton (Luecke et ai., 1990; Jeppesen et aI., 1997), a phenomenon that is often attributed to increased density of inedible phytoplankton such as cyanobacteria (eg, De Bernardi and Guisanni, 1990). Whole-lake (S~ mdergaard et ai., 1997) and enclosure (He and Wright, 1992) experiments support the structuring role of 0+ fish. How the impDrtance of top-down control of zooplankton by fish varies along a trophic gradient is debated extensively. McQueen et ai.(1986) suggested that the cascading effect of zooplanktivorous fish is stronger in oligotrophic lakes than in eutrophic lakes, but a growing body of literature argues that the cascading effect of fish is greater in eutrophic and hypertrophic lakes with respect to the food web in the classic sense
