These rates express which share of the population is grazed per unit time, independent of the relative or absolute abundance of a species. Therefore, a change of wi with abundance (Fig. 3) is no mathematical artifact but a real change of behaviour (Sterner,
1989). Because of the contradiction to the optimal foraging theory and because of the morphological constraints of gastropod radular grazing (Hawkins and Hartnoll,1983), I suggest that the observed change of grazing selectivity is not due to individual
picking of preferred cell types. It could be an indirect consequence of the changes in spatial structure (`architecture' sensu Wetzel, 1983) of the periphyton
community during the colonization process. Initially, when biomass is low, most algae grow on the primary substratum. The strength of attachment to the substratum
might be decisive for grazing resistance. Later, the unicellular algae on the primary
substratum become overgrown and shaded by filamentou

这些率表达人口的哪个份额每个单位时间,种类的相对或绝对丰盈的独立吃草。 所以, wi的变动以丰盈(图3)是没有数学人工制品,但是更加严厉的行为的真正的变动(
1989)。 由于对优选的搜寻理论的矛盾和由于形态限制腹足动物radular吃草(Hawkins和Hartnoll 1983),我建议吃草选择性的被观察的变动不归结于个体 首选的细胞类型picking。 它可能是变化的一种间接后果在空间结构(“建筑学’ sensu Wetzel上的1983) periphyton 在殖民化过程期间的community。 最初,当生物量是低的时,多数海藻在主要下层增长。 附件力量下层的
