Venus Flytrap Seedlings Show Growth-Related Prey Size Specificity

Table 2

Change in number of traps of Venus flytrap seedlings under different prey availability. SWCP is the provider of 60 plants. Related 1 is 60 plants grown from seed and divided into the treatment subsets. Related 2 is a further 60 plants grown from seed and divided into the treatment subsets.
