Abstract
The Santa Cruz Channel is located in the Estuarine Complex of Itamaracá,
between the coordinates of 7°34’00’’ – 7°55’16’’S and 34°48’48’’ –
34°54’24’’W, northeast of Brazil. This channel is one of the most important
productive areas of the littoral zone in the Pernambuco State. Due to the
important environmental conditions, its phycological flora diversity is
represented by 252 species, distributed in 108 Bacillariophyta, 80 Rhodophyta,
19 Phaeophyta and 45 Chlorophyta. Some representatives of economic value are
found, such as Hypnea musciformis (Wulfen in Jacquin) J. V. Lamour., Solieria
filiformis (Kuetz.) P. W. Gabrielson (carrageenan producers), Gracilariopsis
lemaneiformis (Bory) Dawson, Acleto et Foldvik. Hydropuntia caudata (J.
Agardh) Gurgel & Fredericq and H. cornea (J. Agardh) M. J. Wynne (agar
producers). Other species, like H. opuntia (L.) J.V. Lamour, have a high
ecological role in the reef bottom.

1 Introduction
The biodiversity comprises not only the morphological variations of the
organisms but also its genetic and ecological variations [12]. In the sea is found
one of the highest biodiversities of the world that is a function of the algae
diversity [10]. When considering the representation of different plant groups in
the marine flora in terms of numbers of species, it is important to remember that
species vary enormously in number of individuals and in the size of those
individuals, and that the number of species described in any one group probably
