Proposal of a fertility index of Hypnea for ecophysiological studies

Few studies of natural populations of the red algae Hypnea musciformis have been conducted. To enhance our knowledge, it would be helpful to define methodologies that explore the species' adaptability to different environments and seasons. Tetrasporophyte is the most frequent reproductive stage...
