“…Gulliksen (1980) found it "of crucial importance for the overall fauna composition" in a Norwegian fjord. Other solitary ascidians have been reported to show similar competitive ability: Molgula manhattansis {Fry, 1975;Dean & Hurd, 1980), Dendrodoa grossularia (Gulliksen, 1975), Ascidiella aspersa (this study), and a number of other species can dominate fouling assemblages (Sutherland, 1974;Osman, 1977;Marshall et al, 1980). Mussels (Mytilus edulis] characterized established communities and, possibly, the stable point at Station B at Helgoland.…”

The development of hard bottom comnlunities has been studied on test panels in Helgoland Harbour (German Bight) since 1977. Settlement and growth of epibenthic species was examined monthly. Natural variation in different seasons, years, and at three stations (the latter, only in 1981 and 1982) was investigated. At Station A (Binnenhafen), barnacles (Balanus crenatus) and polychaetes (Polydora cillata) were always among the first settlers in spring. They were followed by other barnacles (Elminlus modestus, Balanus improvisus] and by colonial ascidians (Botryllus schlosseri). The latter species often dominated from August to October, and tended to overgrow the barnacle populations. E. modestus showed strong annual variation, probably due to extremely low winter temperatures: after the cold winter of 1978/79, its populations were less dense than in previous years. In 1981 they recovered, and settlement increased again, but the cold winter 1981/82 damaged the population again. At Station B (Nordosthafen), mussels (Mytllus edulls) soon covered barnacles and empty space. By October they had monopolized the fouling community. At Station C (Siidhafen}, barnacle settlement in spring was followed by an overgrowth of hydrozoans (Laomedea spec.). In summer, ascidians (Clona lntestinalls and Ascldlella aspersa) settled and began to dominate. Barnacles were weaker in the competition for space as opposed to later colonizers at all three stations.

“…Several studies have addressed different aspects of the population dynamics of C. montagui and E. modestus, such as densities from newly settled larvae to adults, reproduction and recruitment periods, settlement characteristics and influence on juvenile and adult abundances (see Fry 1975;Harms and Anger 1989;Southward 1991;O'Riordan et al 2004;Cruz et al 2005;Power et al 2006). While classical population dynamics studies, based on densities and size-frequency distributions, have been conducted for several barnacle species (see Wu and Levings 1979;Dye 1993;Jenkins et al 2001;Chan and Williams 2004), to our knowledge only one study appears to have focused on E. modestus (Anger 1978) and none have focused on C. montagui.…”

Secondary production, calcification and CO2 fluxes in the cirripedes Chthamalus montagui and Elminius modestus

Calcification, a process common to numerous marine taxa, has traditionally been considered to be a significant source of CO(2) in tropical waters only. A number of relatively recent studies, however, have shown that significant amounts of CO(2) are also produced in temperate waters, although none of these studies was carried out on rocky shores, which are considered to be very productive systems. We compared the CO(2) fluxes due to respiration and calcification in two temperate species, the cirripedes Chthamalus montagui and Elminius modestus. The population dynamics of both species were estimated at two sites during a 1-year experimental period in order to establish mean organic (ash-free dry weight) and CaCO(3) (dry shell weight) production. Based on these parameters, we estimated the CO(2) fluxes due to respiration and calcification. CaCO(3) production was estimated to be 481.0 and 1,803.9 g(CaCO3) m(-2) year(-1) at each site, representing 3.4 and 12.7 mol(CO2) m(-2) year(-1) respectively, of released CO(2). These fluxes represent each 47% of the CO(2) released as a result of respiration and calcification. The production of CaCO(3) at the high-density site was: (1) among the highest values obtained for temperate organisms, and (2) comparable to the estimated CO(2) fluxes for coral reefs. As calcifying organisms are well represented in temperate ecosystems in terms of both density and biomass, our results provide clear evidence that calcification of temperate organisms should not be underestimated. Additional studies on other rocky shore taxa are needed before the relative importance of calcification in rocky intertidal carbon budgets can be generalized.
