Of these three techniques, underwater visual estimation is the most commonly-used method to record the size of M. alfredi; typically, disc width (DW, defined by Notarbartolo Di Sciara [15] as the greatest dimension between the outermost tips of the pectoral fins) is estimated based on the...
effect of temperature on RL was highest for the articulated alga and lowest for Variations in light exposure and water chemistry during the experiment. Organisms were exposed to diurnal variations in solar radiation under three different light treatments (see Materials and meth- ods). Solar ...
