“…Other potentially important processes that can explain spatial variability at this scale, such as variation in recruitment (e.g. Menge et al 1993) and the requirements for habitat, are currently under investigation. These results were not confounded by temporal variability because the only scale at which this might have occurred was at the regional scale, where no variation was observed for R. verruculosa.…”

“…Some authors have demonstrated that distance of the patch from potentially colonizing organisms is an important factor influencing patch colonization in marine habitats (e.g. Sousa, 1984;Virnstein and Curran, 1986;Edgar, 1992), but this is not always the case (Menge et al, 1993). The patterns of colonization in this study were not often synchronous with, or in the same direction as, the changes in abundances of the natural turfs.…”

Role of colonization in spatio-temporal patchiness of microgastropods in coralline turf habitat

The ability of benthic macrofauna to disperse and colonize new habitats throughout their life may contribute substantially to small-scale patchiness in abundances in different habitats. Microgastropods in coralline turf on rocky shores in Australia are very patchy in abundance at different spatio-temporal scales. They therefore represent an ideal assemblage for testing hypotheses about processes of colonization. Patterns and rates of colonization of 10 species of microgastropods were investigated in one intertidal habitat (coralline turf) in Botany Bay, New South Wales, Australia, using artificial substrata, which are considered to be a good mimic of natural coralline turfs. The experiment was designed to test the hypotheses that (1) patterns (abundance of colonizing individuals) and mode (juveniles vs. adults) of colonization depends on the proximity of a patch to a potential source of dispersing colonists (i.e. patch of natural coralline turf), (2) different species show different rates of colonization, and (3) patterns of succession are not repeatable among different patches of natural algae. Seven different plots (natural patches of coralline turf) were randomly chosen in the area of study. Artificial units (called patches) were placed at different distances around each plot (within the plot and 0, 50 or 100 cm away from the edge). Samples were collected 6, 13, and 27 days after the experiment started. Colonization was rapid (i.e. within 6 days) for most species. Pattern (number of individuals) and mode of colonization (adults vs. juveniles) varied among algal plots. Most species responded differently across patches causing no consistent patterns of colonization. Furthermore, patterns of colonization of artificial units were not always synchronous with, or in the same direction as, changes in abundances in the nearest algal plots, which themselves showed no consistent spatio-temporal pattern.

“…Phymatolithon lenormandii and Chondrus crispus). This may suggest that in the western location diVerent alga and invertebrate assemblages are mainly distributed in patches within zones thus forming a mosaic community (Menge et al 1993). In recent years, it has been realised that most intertidal algae and invertebrates are distributed extremely patchy within any height on rocky shores (Aberg and Pavia 1997;Benedetti-Cecchi 2001;Chapman 2002;Fraschetti et al 2005).…”

Community composition of the rocky intertidal at Helgoland (German Bight, North Sea)

At the rocky island of Helgoland (North Sea), the distribution and abundances of intertidal communities were assessed and the eVects of wave exposure and tidal height on the spatial distribution patterns of the communities were evaluated. Macroalgae and invertebrates were sampled quantitatively along line transects in three intertidal locations, a semi-exposed, an exposed and a sheltered one. The semi-exposed location was characterised by (1) Ulva spp. at the high intertidal (Ulva-community), (2) mussels and periwinkles at the mid intertidal (Mytilus-community) and (3) Corallina oYcinalis and mainly the large brown alga Fucus serratus at the low intertidal (Fucuscommunity). The exposed location encompassed the mid and low intertidal; at both zones the Fucus-community occurred. The sheltered location was characterised by (1) barnacles (Balanus-community) and (2) bryozoans, hydrozoans and mainly the large brown alga Ascophyllum nodosum (Ascophyllum-community). At the semi-exposed, but not at the exposed location the communities changed with the intertidal position. A relationship between wave exposure and the occurrence of speciWc communities was shown for the sheltered location; in contrast, communities of the semi-exposed and the exposed location appear to be little inXuenced by wave exposure directly. The community concept and the potential causes of distribution patterns of the deWned communities are discussed and suggestions for a future monitoring are given. Variations in the communities at diVerent spatial scales speak in favour of a multiple scale sampling design to monitor changes in the intertidal communities at Helgoland.
