“…However, simple biomass or volume of algae has been the most commonly used complexity index (Heck & Wetstone 1977, Stoner & Lewis 1985, Hall & Bell 1988 but this is generally unsuitable as it fails to take into account the varying mass of different algae. Alternatively the surface area of a known weight of algae has been used (Hicks 1977, 1980, Russo 1990) but again because of the varying mass of different algae this does not always adequately represent the order of complexity which might intuitively be expected in a range of algal growth forms (Gibbons 1988b). So far the best measure of complexity appears to be one incorporating both surface area and volume into a ratio .…”

A measure of the complemty of a habltat lndependent of habltat type has long been requlred by benthlc ecologists, particularly when compansons between habitats or substrates need to be made and related to parameters of community structure Using manne algae from the Isles of Scdly, UK, and thelr associated epifaunal communihes as a testbed we have Investigated how the use of fractals may be one method of solvlng some of these problems The fractal dimensions of 4 species of macroalgae with a range of grolvth forms indlcate a n increasing order of compleuity, which is paralleled by differences in the community composlt~on and increasing diversity of 2 different slze fractions of the epifaunal communities associated wlth each alga We conclude that the fractal dimensions of the habitat provlde a numerical expression of complex~ty whlch IS easy to calculate, is Independent of the nature ot the habltat and is related to the scale at which the habltat may be v~e w e d by the size hierarchies of animals which occupy it

“…All these are members of the Rhodophyta except Ascophyllum, Fucus, and Laminaria, which are phaeophytes. Hicks (1977) failed to find Tegastes on a chlorophyte, Enteromorpha, and on two phaeophytes, Xiphophora and Zonaria. Coffin (1979) reported unidentified tegastids from the fronds of four species of red algae (Corallina officinalis, Phycodrys rubens, Phyllophora pseudoceranoides, and Ptilota serrata) and among the haptera of two browns (Agarum cribrosum and Laminaria saccharina).…”

“…The remaining cool-water records are from algae: Delesseriaceae (see Pallares, 1979); Delessaria (see Kunz, 1935); Corallina, Ecklonia, and Pterocladia (see Hicks, 1977); Ahnfeltia, Ascophyllum, and Fucus (see Chislenko, 1967); Laminaria (see Chislenko, 1967; this report); and Ptilota (this report). All these are members of the Rhodophyta except Ascophyllum, Fucus, and Laminaria, which are phaeophytes.…”

“…Habitat features can influence hydrodynamics at small scales (Madsen et al, 2001) and more physically complex patches may supply several different microhabitats. It would allow resource partitioning, as observed for Corallina officinalis, where six species of copepods are specialized on the use of different resources, probably mitigating interspecific competition (Hicks, 1977).…”

Effects of wave exposure on the abundance and composition of amphipod and tanaidacean assemblages inhabiting intertidal coralline algae

et al. 2015

Peracarid crustaceans are an important component of the vagile fauna associated with coralline algal beds, which often characterize the infralittoral fringe of tropical rocky shores. Among other variables affecting faunal assemblages, sedimentation, food supply and oxygen concentration within mats or turfs of coralline algae may greatly depend on the exposure to waves. In this study, peracarid assemblages were compared at replicated rocky shores within different levels of wave exposure, along a coastline in south-eastern Brazil. Overall amphipod diversity (11 species) was much higher than tanaidacean diversity (two species). Correlation analyses did not support any biological interactions between amphipods and tanaidaceans. Habitat complexity, while apparently limiting amphipod populations, did not affect tanaidaceans at a local scale. Amphipod abundance, not assemblage structure, was positively affected by wave exposure, probably improving oxygen concentration levels and renewal of food resources. Rather than abundance, which remains fairly stable, exposure to waves determined species identity in tanaidaceans, with Zeuxo coralensis found at exposed shores and Leptochelia aff. dubia found at sheltered shores, except for two L. aff. dubia individuals found at one of the exposed sites. Differences in the supply of sediment and the ability of these species in manipulating grains for tube building may explain such a striking pattern.
