Seasonal Distribution and Reproductive Status of Macroalgae in Narragansett Bay and Associated Waters, Rhode Island, U.S.A.

Seasonal Distribution and Reproductive Status of Macroalgae in Narragansett Bay and Associated... Abstract This study is the first systematic survey of attached macroalgae at predetermined stations representative of Narragansett Bay and its associated waters. We examined all species found within a 100 m segment of shoreline in both intertidal and upper subtidal zones at 10 widely dispersed stations over 4 seasons (1989 -- 1990). Of 94 species identified, 22 were Chlorophyta, 21 were Phaeophyta, 46 were Rhodophyta and 5 were macroscopic chrysophytes. The R : P ratio of 2.2 fits within a latitudinal gradient of increasing values from the Arctic (0.7) to the Caribbean (4.6) and is higher than that reported 20 years ago for Conanicut Island, R.I. The largest number of species per station was 54, found at the mouth of the bay. In the East Passage and the Sakonnet River, species numbers decreased to 46 and 47 respectively. Fewer than 30 species appeared in the West Passage and just 15 in the northernmost station, although suitable substrata were available. Four species were found at all 10 stations: Ulva lactuca, Petalonia fascia, Ralfsia verrucosa and Scytosiphon lomentaria, and 25 species were found at only one station: Chlorophyta, 4; Phaeophyta, 4; Rhodophyta, 17.
