Number of quadrats and site(s) sampled in the Sydney Region, NSW, Australia on each intertidal rocky-shore from North to South.+
Figure 2.
Mean density of Turbo undulatus on intertidal rocky reefs.
Mean density (+ S.E.; n = 8) of T. undulatus in areas of (a) Hormosira (black bars; quadrat 0.25 m2) and non-Hormosira (white bars), (b) Pyura (dark grey bars; quadrat 0.04 m2) and non-Pyura (white bars) and (c) Corallina (n = 6; quadrat 0.25 m2, grey bars) and non-Corallina (white bars), at each location and at each time of sampling. In areas of unstructured habitat (e.g. non-Hormosira), mean density of individuals are presented above the columns, where needed, due to the small number of individuals.

Analyses of the proportion of small (and thus, large) T. undulatus in intertidal, structured habitats at each location and time of sampling.+
Figure 3.
Mean density of Turbo torquatus on subtidal rocky reefs.
Mean density (+ S.E.; n = 7) of T. torquatus in 5×1 m transects in each of three representative sites of each habitat at Cape Banks at (a) time 1 and (b) time 2.

Analyses of the proportion of small (and thus, large) T. torquatus in structured and unstructured habitats on subtidal rocky reefs at each location and time of sampling.+
