TIDAL HEIGHT AND GAMETOGENESIS: REPRODUCTIVE VARIATION AMONG POPULATIONS OF GEUKENSIA DEMISSA

Abstract: High tidal populations of the mussel Geukensia demissa experience reduced filter feeding time as a result of aerial exposure. This study tested the hypothesis that such populations exhibit a temporal delay in their gametogenic cycle compared to populations from the low intertidal. As predicted, quantitative estimations of gametogenic condition of mussels from 10 high tidal populations were lower than those of mussels from 11 low intertidal populations in May 1986. A two-fold difference in potential feeding tim… Show more

“…In these locations, shell growth was rapid because individuals were continuously submersed, in contrast with those in the intertidal zone. In other bivalves such as scallops, mussels, and oysters, the growth rate also seems to be controlled by food availability (BAYNE & WORRAL 1980, BORRERO 1987, NAVARRO et al 2000, PATERSON et al 2003.…”

“…The timing, duration, and extent of gametogenesis and spawning are influenced by a variety of environmental factors. These include shore level (Ackerman 1971, Bartlett 1972, Suchanek 1981, Borrero 1987, temperature (Elvin 1974, Elvin and Gonor 1979, Hines 1979, and food availability (Pipe 1985). Since epiphytes could modify water flow, temperature, and/ or food availability, one might expect the timing and extent of reproduction to differ within the matched pairs.…”

“…Fig. Furthermore, Borrero (1987) has noted that even within a site, variable access to resources driven by reduced feeding times as a function of increasing distance into the marsh can result in delayed gamete production. Shell-to-tissue ratios of ribbed mussels for each meter into the marsh.…”
