Effects of height on the shore and complexity of habitat on abundances of amphipods on rocky shores in New South Wales, Australia

Effects of macroalgal identity on epifaunal assemblages: native species versus the invasive species Sargassum muticum

“…Morphology and complexity of macroalgae might also be important factors in shaping the structure of these assemblages and determining habitat choice (see Schreider et al 2003;Wernberg et al 2004;Schmidt and Scheibling 2006;Cacabelos et al 2010). For example, certain crustaceans are more abundant in branched macroalgae than in macroalgae with a foliose morphology (McDonald and Bingham 2010).…”

“…In particular, epifaunal assemblages are very influenced by marine macroalgae that exist on the coast, because many invertebrates use macroalgae as a refuge from physical stress, protection from predators, and many of them are herbivores that consume epiphytic algae or the host plant itself (Duffy 1990;Bell 1991;Viejo 1999). There is evidence that different macrophytes support different assemblages of mobile epifauna (Cacabelos et al 2010 and references therein), and this may be due to several biological factors such as life cycles, algal structure (sensu McCoy and Bell 1991;Gee and Warwick 1994), presence of algal epiphytes (Dawes et al 2000), habitat complexity (Buschbaum et al 2006;Schreider et al 2003), chemical defences (Steinberg et al 1998), or physical factors (e.g., wave exposure or tidal height) (Chemello and Milazzo 2002;Schreider et al 2003). Behavioral choices of animals may also account for patterns of distribution, with larger abundance of species in their preferred host habitats (Chapman 2000).…”

Current Patterns in Intertidal Macro-Algal Diversity and Zonation of Two Sites on Ghana’s Coast

“…The importance of Macroalgae and their trophic link with intertidal fauna has been documented by numerous authors [1] the resultant being the proven relevance of these relationships in maintaining species richness and diversity within a community.…”

New Record of a Hyalid Species, Protohyale (Boreohyale) triangulata (Crustacea: Amphipoda: Hyalidae), from Korea

“…The species of Hyalidae Bulycheva, 1957 (Crustacea: Amphipoda) are usually predominant species among macroalgae or mussels inhabiting the intertidal zone and shallow waters of tropical and subtropical regions (Hiwatari and Kajihara, 1981;Hiwatari, 2003;Serejo and Sittrop, 2009), and these small herbivorous species may play important ecological roles in structuring intertidal assemblage (Schreider et al, 2003). Bousfield and Hendrycks (2002) revised the Hyalidae species of the North Pacific Basin based on five characters: hydrodynamic lobes of the gnathopods (anterior lobes of basis and ischium), surge seta and notch of basis on pereopods 5-7, preamplexing notch of female, posterior marginal cusps of coxae 1-4, and forms of oostegites and marginal setae.…”
