Abstract
The seasonal growth and reproduction of the red alga D. incrassata (O.F. Muller) Lamouroux are described from 2 New Hampshire, USA, sites in relation to a variety of environmental factors. The plant''s maximum abundance and reproduction occur during the winter-spring period of low temperatures (less than 10.degree. C) and high nutrients. Several interrelationships are described between growth, reproduction and habitat, including alterations of phenology and the inverse synchronization of growth and reproduction. The gametophytic generations of D. incrassata have a more restricted seasonal periodicity than the asexual plants. Tetrasporic plants are dominant even though asexual and sexual plants occur in a ratio of 1:1. The spores of D. incrassata are liberated during the spring-summer and germinate during the fall.This publication has 4 references indexed in Scilit:
