“…Histochemical studies notwithstanding, glycogen does not appear as the major storage product in Actinia equina, where it ranges seasonally from 1.4% to 3.6% of dW (Ortega, Lopez and Navarro, 1988), or in Metridium senile or Anthopleura xanthogrammica, where it accounts for 1% and 4% of body dry weight, respectively (Giese, 1966). A coordinated seasonal study of glycogen storage and mobilization during the annual reproductive cycle is necessary before the quantitative importance of this storage product can be stated with certainty.…”

“…Lipogenesis in the oocytes of the deep sea species Paracalliactis stephensoni appears to be initiated by the arrival in the abyss of particles derived from the spring bloom of phytoplankton ( Van-Praet and Duchateau, 1984), and coincides with an increase in amylase activity in this species (section 2.4, page 78). In Actinia equina glycogen increases in oocytes and other cells during gametogenesis (Boury-Esnault and Doumenc, 1979), but fluctuation in glycogen and lipid levels is not pronounced in this species (Ortega, Lopez de Pariza and Navarro, 1988), some populations of which do not show a strong seasonality of reproduction (Chia and Rostron, 1970;Schafer, 1981; but see Carter and Miles, 1989). Whether variation in food availability affects egg quality (i.e.…”

“…Lophelia pertusa from Mingulay reef did, however, not display a seasonal trend in total amount of storage lipids (Dodds et al 2009). CWCs could make use of additional carbon storage in carbohydrates, such as glycogen, like anemones (Fitt and Pardy 1981;Ortega et al 1988;Zamer and Hoffmann 1993) and zooxanthellate corals (Kopp et al 2015), but this remains to be verified.…”

Cold-water coral (CWC) reefs are hotspots of biodiversity and productivity in the deep sea, but their distribution is limited by the availability of food, which undergoes complex local and temporal variability. We studied the resource utilization, metabolism, and tissue storage of CWC Lophelia pertusa during an experimentally simulated 3-day food pulse, of 13 C 15 N-enriched phytodetritus, followed by a 4-week food deprivation. Oxygen consumption (0.145 μmol O 2 [mmol organic carbon {OC}] −1 h −1 ), release of particulate organic matter (0.029 μmol particulate organic carbon [POC] [mmol OC] −1 h −1 and 0.005 μmol particulate organic nitrogen [mmol OC] −1 h −1 ), ammonium excretion (0.004 μmol NH 4 + [mmol OC] −1 h −1 ), tissue C and N content, and fatty acid (FA) and amino *Correspondence: sandra.maier@nioz.nlThis is an open access article under the terms of the Creative Commons Attribution-NonCommercial-NoDerivs License, which permits use and distribution in any medium, provided the original work is properly cited, the use is non-commercial and no modifications or adaptations are made.

“…The clear shallow waters that serve as primary habitat to tropical corals and sea anemones are characteristically low in available nutrient levels (Hopley 2011;Mohamed et al 2019;Schwartz 2005), with dependent species relying on high nutrient recycling adaptations, storage mechanisms, and a capacity for efficient nutrient capture in the water column (Ortega et al 1988;Savage 2019). At low nutrient levels, corals, sea anemones, and algae coexist.…”

The coastal waters of Malaysia have been known to allow proliferation of sea anemone assemblages, which are resident species of tropical coral reefs. Along the Perhentian Islands of Terengganu, no efforts have been made thus far to investigate the presence and population dynamics of sea anemone assemblages locally. In this study, Heteractis magnifica assemblages at Village Reef at Perhentian Kecil were monitored during May, July, and August of 2020, thus providing a first assessment of their abundance. Sea anemone formation size, individual size, habitat location, and hosting status of anemonefish were assessed. Results demonstrate significantly larger counts of individuals within aggregated formations in the patch reef as compared to the fringe reef, without the presence of larger individual sizes. In addition, Heteractis magnifica specimens that were actively hosting anemonefish had significantly larger cover, larger individual sizes, and demonstrated higher individual counts within their aggregated formations compared to non-hosting specimens. There was no significant overall effect of time on sea anemone growth throughout the monitoring period, nor were there any significant changes in abundance levels regarding formation make-up throughout the monitoring phase. However, time related effects where present upon data inspection per assessment period. The restricted time frame of the monitoring period could play a role in explaining the absence of overall time related effects. A prolonged monitoring will help to further understand Heteractis magnifica population dynamics at this location, which can increase knowledge capacity for reef management and conservation strategies.
