Phyllospora Comosa
''Phyllospora comosa'', known as crayweed, is a species of brown algae in the Seirococcaceae family that is a type of temperate seaweed forest important as habitat for many marine species and also for producing oxygen and capturing atmospheric carbon. It is found in the oceans around Australia and New Zealand. Crayweed grows up to in length and forms dense, shallow forests. It is abundant in cooler waters along the south-eastern coastline of Australia, around Tasmania and in South Australia and occurs to a depth of around on the east coast and farther south to about . On some Tasmanian coasts it can occur depths of at . It used to occur around Sydney but has disappeared from metropolitan areas under pressure from human activities during the 1970s and 1980s. The algae have a central main axis, usually up to long, which bear many branches along their length, with closely arranged, leaf-like laterals. Some laterals have conceptacles, in which develop cells which produce sperm a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Brown Algae
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 ...

South Australia
South Australia (commonly abbreviated as SA) is a state in the southern central part of Australia. It covers some of the most arid parts of the country. With a total land area of , it is the fourth-largest of Australia's states and territories by area, and second smallest state by population. It has a total of 1.8 million people. Its population is the second most highly centralised in Australia, after Western Australia, with more than 77 percent of South Australians living in the capital Adelaide, or its environs. Other population centres in the state are relatively small; Mount Gambier, the second-largest centre, has a population of 33,233. South Australia shares borders with all of the other mainland states, as well as the Northern Territory; it is bordered to the west by Western Australia, to the north by the Northern Territory, to the north-east by Queensland, to the east by New South Wales, to the south-east by Victoria, and to the south by the Great Australian Bight.M ...

Sydney
Sydney ( ) is the capital city of the state of New South Wales, and the most populous city in both Australia and Oceania. Located on Australia's east coast, the metropolis surrounds Sydney Harbour and extends about towards the Blue Mountains to the west, Hawkesbury to the north, the Royal National Park to the south and Macarthur to the south-west. Sydney is made up of 658 suburbs, spread across 33 local government areas. Residents of the city are known as "Sydneysiders".

The traditional custodians of the land on which modern Sydney stands are ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Algae
Algae (; singular alga ) is an informal term for a large and diverse group of photosynthetic eukaryotic organisms. It is a polyphyletic grouping that includes species from multiple distinct clades. Included organisms range from unicellular microalgae, such as ''Chlorella,'' ''Prototheca'' and the diatoms, to multicellular forms, such as the giant kelp, a large brown alga which may grow up to in length. Most are aquatic and autotrophic (they generate food internally) and lack many of the distinct cell and tissue types, such as stomata, xylem and phloem that are found in land plants. The largest and most complex marine algae are called seaweeds, while the most complex freshwater forms are the ''Charophyta'', a division of green algae which includes, for example, ''Spirogyra'' and stoneworts. No definition of algae is generally accepted. One definition is that algae "have chlorophyll ''a'' as their primary photosynthetic pigment and lack a sterile covering of cells around thei ...

Conceptacles
Conceptacles are specialized cavities of marine and freshwater algae that contain the reproductive organs. They are situated in the receptacle and open by a small ostiole.Boney, A.D. (1969). ''A Biology of Marine Algae''. Hutchinson Educational Ltd, London Conceptacles are present in Corallinaceae,Irvine, L.M. and Chamberlain, Y.M. (1994). ''Seaweeds of the British Isles''. Volume 1, Part 2B. Natural History Museum, London. and Hildenbrandiales, as well as the brown Fucales. In the Fucales there is no haploid phase in the reproductive cycle and therefore no alternation of generations.Fritsch, F.E. (1945). ''The Structure and Reproduction of the Algae''. Vol 2.

Coogee, New South Wales
Coogee is a beachside suburb of local government area City of Randwick 8 kilometres south-east of the Sydney central business district, in the state of New South Wales, Australia. It is typically associated as being part of the Eastern Suburbs region. The Tasman Sea and Coogee Bay along with Coogee Beach lie towards the eastern side of the suburb. The boundaries of Coogee are formed mainly by Clovelly Road, Carrington Road and Rainbow Street, with arbitrary lines drawn to join these thoroughfares to the coast in the north-east and south-east corners. History Aboriginal The name Coogee is said to be taken from a local Aboriginal word ''koojah'' which means "smelly place". Another version is ''koo-chai'' or ''koo-jah'', both of which mean "the smell of the seaweed drying" in the Bidigal language, or "stinking seaweed", a reference to the smell of decaying kelp washed up on the beach. Early visitors to the area, from the 1820s onwards, were never able to confirm exactl ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
