“…Assimilation of these I3C-depleted stable carbon isotope sources could help explain the fauna1 isotope ratios. Concentrations of both methane and sulfide in the Mayan Blue system were low (see 'Results'), but low concentrations of these compounds can support chemoautotrophic production by methanotrophic and sulfide-oxidizing bacteria (Dando et al 1985, Ward & Kilpatrick 1990.…”

ABSTRACT. Stable carbon and nltrogen isotope data, complen~ented wlth other geochemical parameters, were used to Identify the sources of organic mattrr that support the food web of an anchialine cave ecosystem In the northeastern Yucatan Peninsula, Mexlco. A n c h~a l~n e caves, coinmon along tropical kal-st~c and volcan~c coastlines, are completely or partially Inundated by highly stratified layers of fresh and marine waters. Stable isotope data from the cave fauna, the particulate organlc matter (POM) from the cenote pool and from the cave, the forest soil and the cave sedlmcnts ~ndicated that at least 3 soul-ces of nutritive organics could support the anchialine food web. Thcsr sources were. (1) soil from the overlying forest; (2) freshwater algae from adjoining open water pools; and (3) chernoautotrophic nitrifying bactei-la living in the cave. Production of nitrate a n d a tlccrcasc in O2 along the halocline provided geochemlcal evidence of nitrification. Stable nitrogen isotope datd defined 2 to 2.5 trophic levels In the food web. Furthermore, it was found that troglobitic (cave-limited) species res~ding In the water column a r e cilpable of preferentially feeding on specific organic reservoirs. This study presents the first extensive description of the ecological and biogeochemical relationships of the anchialine cave ecosystem.

“…This tubular structure increases the surface area of the bacteriocyte zone and creates a more rigid network further facilitating the movement of water from the infra-branchial chamber to the supra-branchial chamber. Similar structures are present within the Lucinoidea; Dando et al (1985) noted the inter-lamellar bridges in Myrtea spinifera and Distel and Felbeck (1987) illustrated a complex tubular structure in Lucinoma aequizonata. Such complex structures are found throughout the Lucinoidea but this gill differs in consisting of a only a single demibranch (Taylor and Glover 2010).…”

Three dimensional tubular structures of the ctenidium of some thyasirid bivalves are described for the first time. The classification of the thyasirid gill is modified accordingly into five types based on the number of demibranchs, reflection of the filaments and shape of the filaments, either rod, laminar or tubular. The tubular structure is seen in its most modified form in a chemosymbiotic abyssal species from the south-east Atlantic, which is described here as Ochetoctena tomasi gen et sp. nov.

“…concentration < 0.1 µM; Dando et al 1985), the 13 C content of Thyasira sarsi tissues was much higher. In some specimens it approached the values found in heterotrophic bivalves in the same sediment, -17.4 to -17.1 ‰ δ 13 C (Dando & Spiro 1993).…”

Several bivalve molluscs, including species of Thyasira (family Thyasiridae), use symbiotic sulphur-oxidising bacteria to exploit sulphides in reducing sediments are able to oxidise the insoluble sulphides as well as dissolved sulphide. The behaviour of these bivalves was observed in narrow glass vessels. Rates of sulphide oxidation by Thyasira sarsi (Philippi) were determined in a mesocosm, using specimens and sediment from Oslofjord. . This suggests that sulphate reduction rates control density in T. sarsi populations. The activities of T. sarsi and other lucinaceans can re-oxidise reducing and polluted sediments, allowing colonisation by sulphide-intolerant benthic animals.
