Dictyotaceae
Dictyotaceae is large family (biology), family of brown algae (class Phaeophyceae). Members of this family generally prefer warmer waters than other brown algae. ''Lobophora variegata'' (= ''Pocockiella varieagata'') often presents a beautiful blue iridescence due to microscopic bacteria which live on the surface of the blades . A number of genera are known as forkweed (e.g. ''Dictyota'', ''Glosophora'', ''Dilophus'', ''Dictyopteris'', ''Pachydictyon'' and ''Lobospira''.

Dictyota
''Dictyota'' is a genus of brown seaweed in the family Dictyotaceae. Species are predominantly found in tropical and subtropical seas, and are known to contain numerous chemicals (diterpenes) which have potential medicinal value. As at the end of 2017, some 237 different diterpenes had been identified from across the genus. Taxonomy and Nomenclature The genus ''Dictyota'' was first described by Jean Vincent Lamouroux in 1809. The name ''Dictyota'' is derived from the Greek word “Διχτυον” meaning “net” or “network”, referring to the inner cellular structure of specimens when viewed under a microscope, which features netted cortical and medullary cells. ''Dictyota'' belongs to the order Dictyotales and the SSDO-clade, which also includes the orders Sphacelariales, Syringodermatales, and Onslowiales. The family Dictyotaceae is divided into two tribes: Dictyoteae and Zonarieae. The former have a single lens-shaped apical cell from which the thallus grows, while ...

Lobophora Variegata
''Lobophora variegata'' is a species of small thalloid brown alga which grows intertidally or in shallow water in tropical and warm temperate seas. It has three basic forms, being sometimes ruffled, sometimes reclining and sometimes encrusting, and each form is typically found in a different habitat. This seaweed occurs worldwide. It is the type species of the genus '' Lobophora'', the type locality being the Antilles in the West Indies. Description ''Lobophora variegata'' has three different morphological forms; an erect ruffled form, a decumbent or reclining form which grows flattened against the substrate and an encrusting form. Each of these forms may dominate its habitat. This seaweed is generally greenish-brown or pale brown. The sporangial sori are scattered across both surfaces of the thalli (fronds). The ruffled form grows in ball-like clumps of wavy fronds as a result of the continued growth of the lateral blades. It is most often found in sandy areas and among tu ...

Phaeophyceae
Brown algae (singular: alga), comprising the class Phaeophyceae, are a large group of multicellular algae, including many seaweeds located in colder waters within the Northern Hemisphere. Brown algae are the major seaweeds of the temperate and polar regions. They are dominant on rocky shores throughout cooler areas of the world. Most brown algae live in marine environments, where they play an important role both as food and as a potential habitat. For instance, ''Macrocystis'', a kelp of the order Laminariales, may reach in length and forms prominent underwater kelp forests. Kelp forests like these contain a high level of biodiversity. Another example is ''Sargassum'', which creates unique floating mats of seaweed in the tropical waters of the Sargasso Sea that serve as the habitats for many species. Many brown algae, such as members of the order Fucales, commonly grow along rocky seashores. Some members of the class, such as kelps, are used by humans as food. Between 1,500 and ...

Zonaria (alga)
''Zonaria'' is a genus of thalloid brown alga comprising approximately 12 species. Specimens can reach around 25 cm in size, all of which exhibit a characteristic semi-circular growth pattern which produces distinct alternating patterns of darker and lighter tissue akin to tree rings. ''Zonaria'' produces tetraspores. ''Zonaria'' is widespread with some species being locally abundant upon shallow subtidal of rock reefs. The species currently recognised are: The three ''Zonaria'' Australian species ''Z. turneriana'', ''Z. crenata'' and ''Z. angustata'' produce phloroglucinol derivatives.

Dictyota Dichotoma
''Dictyota dichotoma'' is a species of Brown algae found in the temperate western and eastern Atlantic Ocean, the Mediterranean Sea, the Black Sea, the Red Sea and the western Indian Ocean. Description The thallus of ''Dictyota dichotoma'' grows in tufts and is a yellowish-brown or greenish colour, with a faint bluish iridescence when underwater. It forms membranous, flattened, dichotomously-branching fronds up to long and wide. These have a reticulated (net-like) structure and no midrib. The tufts are semi-erect and have little or no stalk; they are anchored to the seabed by rhizoids, filamentous outgrowths that can absorb nutrients from their surroundings. The thallus branches are strap-like, the branches being equal in length and having rounded ends. Clusters of spores develop in round or oval sori under the surface of the thallus, finally bursting through. Distribution and habitat ''Dictyota dichotoma'' has a wide range, being found in the western Atlantic Ocean and the ea ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
