“…The mangrove microclimatic thermal conditions regulate the aerial temperature, which consequentially modulated interstitial temperatures at the location. The direct relationship between air temperature and the temperature of tidal flats has long been noted (Eltringham, 1971; Kennedy et al , 1974). Temperature of exposed (low tide) interstitial water may rise too high when the sun is shining or fall abruptly in the rains.…”

Here we report novel data on the ecology and diversity of West African estuarine biological communities, with emphasis on the opisthobranch gastropod, Haminoea orbignyana. Macrofaunal samples were obtained from five intertidal flats within Bodo Creek in the lower Niger Delta during two years (May 2006-April 2008 to investigate diversity and community assemblages of epimacrofauna. A total of 601 individuals belonging to 18 species were recorded, with density varying between 4 ind.m 22 and 660 ind.m 22 . Gastropods (predominantly Pachymelania aurita and H. orbignyana) accounted for 92.3% of the community abundance, followed by malacostraca crustaceans (7.7%). Diversity varied (P , 0.05) between locations, with the mangrove swamp station having higher richness, diversity and evenness values than the open intertidal flat locations. The species H. orbignyana was only found on downstream sampling sites reaching a maximum density of 52 ind.m 22 . The species seems to recruit during November/December and likely attains a maximum life span of about 18 months.

“…virginica (8.30 m m S-') and Ostrea edulis (6.00 mm S-') (Walne 1965); however, sinking rate for 0, edulis was calculated for larvae swimming at 21 "C and ca 31 to 32 %o. & Haskin (1978) suggest a linear relationship between sinking rate and larval length while Chia et al (1984) Gallager et al 1986, Lucas et al 1986 (Cain 1972(Cain , 1973 for Rangia cuneata, Kennedy et al 1974 for Mulinia lateralis, Roosenburg et al 1984 Harder (1968) and Mann (1988) report o n responses o f other bivalve larvae to laboratory-generated salinity discontinuities. Harder (1968) salinity (16.51 over 33.75 %o) resulted in the return of the larvae to the lower, high salinity layer suggesting that the lower salinity was below the optimum for the species.…”

“…Adults were induced to spawn by thermal stimulation (Kennedy et al 1974, Goldberg 1980, Wright et al 1983. Water temperature was raised to 24 "C for Spisula solidissima, to 28 "C for Mulinia lateralis and to 32 "C for Rangia cuneata.…”

“…In reality bivalve larvae do not encounter such high salinity discontinuities. The rationale for selection of these values was to include extremes of the range of tolerance of each species (Chanley 1965, Calabrese 1969, Cain 1973, Castagna & Chanley 1973, Kennedy et al 1974, Roosenburg et al 1984) that could probably be encountered by larvae during their dispersal. The design assumes that if larval distribution was not affected by these extreme discontinuity values, then lower magnitudes or gradients as encountered in the field would make little or no difference to larval swimming behaviour.…”

Straight-hinge, umbo and pediveliger larvae of the mactrid bivalves Spisula solidissima, Mulinia lateralis and Rangia cuneata were exposed to intense salinity discontinuities of 0, 5, 10 and 15 O/w in vertically oriented swimming chambers. Larvae concentrated in the region of highest gradient, i. e. at the salinity discontinuity, regardless of species, stage of development or larval brood. S. solidisima larvae, initially swimming at 30 O/w salinity, crossed discontinuities of both 5 and 10 %O but not of 15 %o. M. lateralis larvae, initially swimming at 25 %O salinity, also crossed a discontinuity of 5 %O but not of 10 or 15 %o. R. cuneata larvae, initially swimming at 10 %O salinity, generally preferred to remain at that salinity. Swimming and passive sinking velocities, defined as vertical distance traversed per unit time, were measured in different salinities under constant temperature and light. For all species, swimming rate changed with larval stage, highest velocity occurring at the umbo stage. Upward swimming rate of S. solidissima larvae ranged from 0.18 to 0.49 mm S-' and increased with increasing salinity. Upward swimming rate of M. lateralislarvae ranged from 0.25 to 0.50 mm S-', but was not consistently related to salinity. Upward swimming rate of R. cuneata larvae ranged from 0.18 to 0.53 mm S-'; swimming rate of pediveliger larvae increased consistently as salinity decreased. Downward swimming rates were similar to upward rates. No significant differences in downward swimming rate were detected in relation to salinity. Passive sinking was more frequent than active downward swimming in umbo and pediveliger larvae. Sinking rate increased with larval size of S. solidissima and M. lateralis larvae; however, R. cuneata straight-hinge larvae sank faster than umbo and pediveliger larvae. Species-specific differences in larval sinking and swimming are related to the different habitats occupied by adults. Larvae of S. solidissima, a marine stenohaline species, remained in high salinity water. Larvae of M. lateralis, a euryhaline species, use their preference for discontinuities or higher salinity water to assist retention in partially mixed estuaries. High sinking rate and short larval period of R, cuneata may offset the behavioural characteristic and aid in the retention of R. cuneata larvae in the low salinity zone of most partially mixed estuaries.

“…M. lateralis has been well studied with respect to its salinity and temperature tolerances from eggs through adults both in the field and in the laboratory. Kennedy et al (1974) demonstrated that temperature sensitivity decreased in the following order: 2-3 hour cleavage stage, trochophore larvae, straight hinge veliger. Calabrese (1969bCalabrese ( , 1970 and Calabrese & Rhodes (1974) showed that although the larvae grew in temperature/salinity combinations ranging from 20-300/00 and 20-30°C, optimal conditions for embryos were 22.5 -300/00 and 15 -25°C while optimal conditions for larvae ranged from 20-27%0 and 7.5-2rc.…”

The effects of intrinsic (body size, gill surface area and activity patterns) and extrinsic (temperature, salinity and oxygen concentration and food) factors on oxygen consumption were measured in the mactrid clam Mulinia lateralis. Both acclimated and acute rates of VO, were measured under 9 salinity-temperature combinations and a model is presented which indicates that: 1) body size is the over-riding factor determining VO" 2) acclimation temperature alone has no significant effect on either fed or starved animals 3) the interaction of acclimation temperature and salinity and exposure salinity is the strongest factor influencing VO, after body size, 4) exposure conditions are more likely to determine energy levels of expenditure than acclimation conditions. Small individuals have a greater gill surface area per body weight than larger individuals. The degree of oxygen independence is dependent on both body size and on acclimation temperature and shows a slight increase after exposure to anoxic conditions. .Patterns of shell valve activity were altered and VO, increased in response to algae, charcoal and algal extract.There was no evidence of a complete temperature acclimation even after 3 weeks.The scope for activity indicates that starved animals at high temperatures are at a greater energetic disadvantage than individuals at lower temperatures. Equations are presented for clearance/pumping rate, convection requirements and utilization efficiencies and indicate that metabolism increases faster in relation to body size than does pumping rate resulting in decreased net energy gain as the animals increase in size.Survival of M. lateralis populations appears to be a combination of behavioural and physiological adaptations which allow successful exploitation of favourable conditions while at the same time leaving the animals vulnerable to long term stress conditions.
