“…Negative correlations between species distributions, however, are only suggestive of competition, and the influence of competition on marine mesoherbivores is poorly understood. In contrast to the above studies, others have found little evidence for competition among epifaunal amphipods based on distributional data and laboratory experiments (Nelson 1979, Stoner 1985, Duffy & Hay 1991b. Similar analyses have not been reported for sponge-associated amphipods, but competition has been invoked as an important determinant of host use in other spongedwelling invertebrates (e.g, the sponge shrimps Synalpheus, Duffy 1996a,b).…”

Marine amphipods commonly use other organisms as both habitat and/or food, offering an opportunity to contrast host associations in marine environments with that of terrestrial invertebrates. A few species of amphipods have been found to specialise on their hosts for habitat or food; however, their host associations remain poorly described and previous studies have confounded habitat and feeding specificity. We examined the patterns of host use for amphipods associated with macroalgae and sponges. For macroalgae, the analysis was limited to strictly herbivorous species in order to address feeding specificity only. On both hosts, amphipods displayed a range of host specificity, from more generalised to more specialised species. Even when not specialised, amphipod species had disjunct distributions, resulting in a distinct assemblage of amphipods associated with each host species. This was true for both herbivorous amphipods inhabiting algae, where host specificity relates to feeding specificity, and for amphipods on sponges, where host specificity is likely to relate to habitat specificity only. For most species of herbivorous amphipods, patterns of host use were largely unrelated to sampling time (day vs night), remained distinct across seasons, and were unaffected by the presence of alternative food sources (epiphytes).

“…The "espera" stage is very rare in the Atlantic populations (Friedmann et al, 1977) while it is commonly found throughout the year in the Mediterranean Sea (Huve & Huve, 1964;Meinesz, 1972). The capitula of P. capitatus support large communities of macrofauna dominated numerically by small Crustaceans, mostly amphipods, tanaidaceans and large harpacticoid copepods (Stoner, 1985).…”

Based on recent biodiversity studies carried out in different parts of the Mediterranean, the following 19 species are included as new records on the floral or faunal lists of the relevant ecosystems: the green algae Penicillus capitatus (Maltese waters); the nemertean Amphiporus allucens (Iberian Peninsula, Spain); the salp Salpa maxima (Syria); the opistobranchs Felimida britoi and Berghia coerulescens (Aegean Sea, Greece); the dusky shark Carcharhinus obscurus (central-west Mediterranean and Ionian Sea, Italy); Randall's threadfin bream Nemipterus randalli, the broadbanded cardinalfish Apogon fasciatus and the goby Gobius kolombatovici (Aegean Sea, Turkey); the reticulated leatherjack Stephanolepis diaspros and the halacarid Agaue chevreuxi (Sea of Marmara, Turkey); the slimy liagora Ganonema farinosum, the yellowstripe barracuda Sphyraena chrysotaenia, the rayed pearl oyster Pinctada imbricata radiata and the Persian conch Conomurex persicus (south-eastern Kriti, Greece); the blenny Microlipophrys dalmatinus and the bastard grunt Pomadasys incisus (Ionian Sea, Italy); the brown shrimp Farfantepenaeus aztecus (north-eastern Levant, Turkey); the blue-crab Callinectes sapidus (Corfu, Ionian Sea, Greece). In addition, the findings of the following rare species improve currently available biogeographical knowledge: the oceanic pufferfish Lagocephalus lagocephalus (Malta); the yellow sea chub Kyphosus incisor (Almuñécar coast of Spain); the basking shark Cetorhinus maximus and the shortfin mako Isurus oxyrinchus (north-eastern Levant, Turkey).

“…Of the 6 most abundant species in this study, epifaunal species were positively affected by the presence of macroalgae, while infaunal species were not affected (Capitella capitata) or negatively affected (Nereis diversicolor). Effects of the presence of algal cover on the macroinvertebrate community have been attributed to modification of biotic interactions, such as predation and availabdity of food or living space (Heck & Thoman 1981, Lewis 1984, Summerson & Peterson 1984, Stoner 1985, Schneider & Mann 1991, and modification of physico-chemical sediment characteristics (Kalejta & Hockey 1991). In the ecosystem studied, the lagoon area used for extensive aquaculture supported large populations of predators (reared fish species and shorebirds).…”

The composition and distribution of the benthic macroinvertebrate community in a lagoon fish-pond system in the Bay of Cadiz. Spain, were studied by taking monthly samples at 4 sites during 1991. A total of 29 macroinvertebrate species, representing 16 orders. were identified. Gastropods, amphipods and chironomid larvae dominated the macrofauna in term of numbers of individuals, while in biomass terms gastropods, bivalves and polychaetes were dominant. The diversity (H') and evenness (J') indices of this community were low, ranging from 0.58 to 1.85 and 0.30 to 0.75 respectively (natural log base). Monthly total invertebrate density showed considerable seasonal variation, with a main peak in winter. Taking the most abundant species only, the densities of Hydrobja minoricensis, H. ventrosa, Microdeutopus gryllotalpa and Chironomus salinarius were positively related, and the density of Nereis diversicolor negatively related, to the biomass of benthic macroalgae (Ulva lactuca and Cladophora sp.). The density of C. salinarius was also positively related to the silt content in the sediment. Mean annual production varied between 13.3 g m-' yr-' ash-free dry weight (50.7 g m-2 yrr' dry weight) and 27.3 g m-' yr-' AFDW (122.0 g m-'yr-' DW) depending on the sampling site, yielding production/biomass (P/B) ratios between 1.08 and 1.37 yr-l. The annual production estimate for the whole system was 19.5 g m-' yr-' AFDW (66.6 g yr-' DW).
