Figure 1From: Effects of intraspecific competition on the life cycle of the stonefly, Nemurella pictetii (Plecoptera: Nemouridae)Head capsule width of larvae of Nemurella pictetii (mean ± SD) with time during the speed of growth and maturation experiment. Aggregate values are shown; low larval density (5 larvae per experimental unit): n = 10; high larval density (20 larvae per experimental unit): n = 9.Back to article page
