Fig. 2From: Laboratory study of Fritillaria lifecycle reveals key morphogenetic events leading to genus-specific anatomyLaboratory culture of F. borealis. A Wild specimen carrying ectoparasites. B Schematic of the procedure for maintaining a laboratory population during the seven days lifecycle. Animal handling steps are indicated with italic font. C Animal production in the laboratory during a 17-weeks period. For each spawn conducted (arrowheads), the number of parents (orange squares) and the number of produced offspring (black dots) have been plotted. Curves show 2 periods moving averages for each series. Spawns were established using animals from the same population, excepted at days 50 and 51, when new populations were established by using animals from populations 1 and 2 in the same spawn. D Average fecundity of adults determined from the offspring counted after laboratory spawnsBack to article page
