MACROALGAS MARINAS DE LA BAHÍA DE SAN QUINTÍN, BAJA CALIFORNIA, MÉXICO

Abstract

In order to know the composition and
distribution of macroalgae species in the
lagoon complex of San Quintin Bay, Baja
California, nine sampled were realized in
three sites during 1988, 1989, 1990, 1995 and
1996; also a bibliographyc revision on the
marine benthic algae cited from the study
area. A total of 37 genera with 46 species of
marine macroalgae were determined, of
which 22 are Rhodophyta, (47.82 %), 12
Phaeophyta (26.08 %) and 12 Chlorophyta
(26.08 %). The floristic list includes data on
the presence and distribution of species
found, reproductive stage, substrate and
epiphytism. The families with best
representation with regard to richness
and occurrence are: Corallinaceae,
Ceramiaceae, Rhodomelaceae (Rhodophyta); Ectocarpaceae, Scytosiphonaceae
(Phaeophyta) and Ulvaceae (Chlorophyta).
18 (39.13 %) represent new records from the
study area. Ulva expansa Linnaeus is
reported for the first time for the occidental
coast of Baja California. The floristc list and
the bibliographyc information were
actualized; the dates show that the number
od species of marine algae from San Quintin
Bay is composed for 59 species.
