The Seagrass Epiphytes of the Indian River, Florida I. Species List with Descriptions and Seasonal Occurrences

Abstract
Algae (41 spp.) occurred as epiphytes on the seagrasses Halodule wrightii, Syringodium filiforme and Thalassia testudinum in the Indian River, Florida. Monthly collections were made at 3 stations and bi-monthly collections were made at 2 stations from Dec. 1977 through Dec. 1978. Species numbers and species abundance were generally highest in the winter and the spring when Rhodophyta and Phaeophyta were most abundant and lowest during the late summer and early fall. Cyanophyta and Chlorophyta occurred relatively consistently throughout the year. The epiphytes are divided into 3 groups based on their seasonal pattern: year-round species, winter-spring species and species of rare or irregular occurrence.
