“…They feed on fine organic matter that settles on the sediments (Sreenivasan and Natatajan 1991), and in Qatar are commonly observed grazing at the edges of algal mats. Based on studies mainly in India, these animals can reproduce year around, but growth is faster in the summer and slower in the winter (Rao and Rao 1983), with optimal growth temperature range of 28-348C (Sreenivasan 1985). The life expectancy of this species is~1 year (Reid and Ozawa 2016).…”

The southern margin of the Arabian Gulf is a ''classic'' shallow-water, evaporative, carbonate-producing setting. The sediments and early diagenetic products creating the ''Great Pearl Bank'' of the United Arab Emirates to the east and accumulating in the coastal regions of Qatar to the west have long been studied as modern analogs for ancient evaporitic carbonate deposits of the rock record. An integrated study measuring the chemistry of Qatar subtidal coastal waters, evaporating tidal-pond waters (to halite saturation), and meteoric pond waters was undertaken encompassing both the dry (fall) and wet (winter/spring) seasons of 2016-2017. Measured parameters included temperature, pH, dissolved oxygen, and alkalinity, as well as major-ion (Na þ , Ca 2þ , Mg 2þ , K þ , Sr 2þ , Cl -, and SO 4 2-) and stable-isotope (d 18 O and dD) composition. Initial concentration by evaporation (to~90 practical salinity units (psu)) is interpreted to drive minor diagenetic aragonite precipitation. Further evaporation initially causes minor aragonite dissolution followed by gypsum and halite precipitation. One pond showed evidence of ongoing replacive dolomitization interpreted to be driven by H 2 S formation and oxidation in association with microbial breakdown of organic matter. The stable-isotope composition of water in restricted ponds is a function of the degree of evaporation and dilution by meteoric waters during the wet season. Unexpectedly, beyond 350 psu, d 18 O and dD continue to rise reaching values greater than 12 and 60%, respectively. The slope of the d 18 O-dD regression line exhibits no differences between dry and wet seasons.During collection of coastal waters (up to~90 psu), live Pirenella cingulata (previously Cerithidea cingulata) gastropods were collected and their shells analyzed for d 18 O and d 13 C, as well as Sr 2þ and Ca 2þ concentration. The d 18 O of water and Pirenella from the same sample site exhibits a strong correlation (R 2 ! 0.85) with a slope of~1, suggesting that the shells may be a useful chemical archive for the isotopic composition of past oceans. The d 18 O and d 13 C of the shells correlate positively, likely reflecting greater sequestration of 12 C into organic matter in more restrictive evaporative settings. The intercept of the d 18 O and d 13 C correlation shifts between dry and wet seasons, and is interpreted to reflect average seawater temperature differences during recent growth. There is also a strong correlation (R 2 ! 0.85) between shell d 18 O and measured water salinity, reflecting their mutual control by degree of evaporation. The Sr 2þ content of the gastropods does not correlate well with any measured oceanographic parameter, or show evidence of systematic seasonal change.

“…There are numerous studies on the oxygen consumption in the intertidal animals, often combined with studies in ventilatory and cardiac activities and haemocyanin function (see reviews of Mangum 1983;McMahon andWilkens 1983 andNewell 1979). The effect of body size in gastropods has been extensively studied by Berg and Ockelmann 1959;Davis 1966;Huebner 1973;Brown et al 1978;Rao and Rao 1984. In addition, the effect of body size on the oxygen consumption of bivalves has also been studied (Nagabhushanam 1957;Lomte and Nagabhushanam 19n;Rao et al 1974;Mane 1975). Travallion (1965) noted, in particular, the ability of Nuculasulcata and Nucula turgida to withstand considerable periods of hypoxia.…”

The effect of temperature on the rate of oxygen consumption and heart rate has been investigated in the Red Sea, inter-tidal wedge clam Donax faba. The 010 values for both oxygen consumption and heart rate were often < 2.5 and were relatively constant over a wide range of temperature. This suggests that wedge clam is well adapted for life in high temperature environment. It was noted, however, that behavioural mechanisms were important in reducing the degree of temperature stress that could be experienced in the field.

“…Several ecological studies have been made on this species: Vohra (1971:694), in an ecological study of zonation along a sandy shore in Singapore, found C. coralium to be common on sticky, sandy areas overgrown with Halophila ovalis. Studies exist on the respiration (Rao and Rao, 1984), starvation metabolism (Rao et al, 1987), and seasonal changes in the levels and content of biochemical constituents (Rao et al, 1988) of C. coralium populations in India. Fecal pellets and stomach contents reveal that this species is a deposit feeder and feeds on diatoms and microalgae comprising the detritus in these habitats.…”

SMITHSONIAN CONTRIBUTIONS TO ZOOLOGY • NUMBER 510 SERIES PUBLICATIONS OF THE SMITHSONIAN INSTITUTIONEmphasis upon publication as a means of "diffusing knowledge" was expressed by the first Secretary of the Smithsonian. In his formal plan for the Institution, Joseph Henry outlined a program that included the following statement: "It is proposed to publish a series of reports, giving an account of the new discoveries in science, and of the changes made from year to year in all branches of knowledge." This theme of basic research has been adhered to through the years by thousands of titles issued in series publications under the Smithsonian imprint, commencing with Smithsonian Contributions to Knowledge in 1848 and continuing with the following active series:
