A novel method of estimating the cell volume of non-testate, free-living amoebae is presented. Measurements of the length (L) of motile forms of some amoebae, obtained by applying some basic rules, can be used to calculate diameter (D) using a relatively simple formula, derived from regression analysis (N=39): D=0.6L. Important physiological and ecological variables, including carbon content and respiratory rate, can then be easily calculated using this estimated cell volume.
本文提出了一种估算无壳、自由生活变形虫细胞体积的新方法。通过应用一些基本规则测量某些变形虫活动形态的长度(L),利用回归分析得出的一个相对简单的公式(N = 39):D = 0.6L,可用于计算直径(D)。然后,利用这个估算出的细胞体积,就可以轻松计算包括碳含量和呼吸速率在内的重要生理和生态变量。
