The effect of diet and temperature on reproductive rate in Arcella vulgaris Ehrenberg (Sarcodina: Testacida)
journal contribution
posted on 2023-05-16, 20:46 authored by Laybourn-Parry, J, Whymant, LThe acceptability of bacterial, algal and fungal food cources as manifested by reproductive rate was investigated in Arcella vulgaris at 5°C intervals between 10°C-25°C. Bacteria and diets containing bacteria produced the highest rates of reproduction, a fungal diet induced the lowest rate of reproduction. On all diets reproductive rate increased with temperature up to 20°C, thereafter levelling out. Generation times were long, ranging from 64 h to 95 h, depending on diet and temperature. Consumption experiments using bacteria as food indicated that energy consumption was independent of temperature. © 1980 Springer-Verlag.
