North Island (Houtman Abrolhos)
North Island is the northernmost island in the Houtman Abrolhos, a coral reef archipelago in the Indian Ocean off the coast of Mid West Western Australia. Located about 14 km (9 mi) from the nearest island group, it is one of the largest islands in the Houtman Abrolhos, and one of the few to support dune systems. It has relatively diverse flora dominated by chenopod shrubs and fauna that includes the introduced tammar wallaby, around seven species of reptile, and about 15 resident bird species. First recorded and surveyed in 1840, North Island has been a seasonal camp for western rock lobster fishermen since the beginning of the 20th century, and this remains the principal focus of human activity on the island. There is also a small amount of tourism, though for the most part it is reserved as conservation habitat for vegetation communities and rare birds. History Discovery The earliest recorded sighting of North Island occurred in May 1840, during the third survey ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Indian Ocean
The Indian Ocean is the third-largest of the world's five oceanic divisions, covering or ~19.8% of the water on Earth's surface. It is bounded by Asia to the north, Africa to the west and Australia to the east. To the south it is bounded by the Southern Ocean or Antarctica, depending on the definition in use. Along its core, the Indian Ocean has some large marginal or regional seas such as the Arabian Sea, Laccadive Sea, Bay of Bengal, and Andaman Sea. Etymology The Indian Ocean has been known by its present name since at least 1515 when the Latin form ''Oceanus Orientalis Indicus'' ("Indian Eastern Ocean") is attested, named after Indian subcontinent, India, which projects into it. It was earlier known as the ''Eastern Ocean'', a term that was still in use during the mid-18th century (see map), as opposed to the ''Western Ocean'' (Atlantic Ocean, Atlantic) before the Pacific Ocean, Pacific was surmised. Conversely, Ming treasure voyages, Chinese explorers in the Indian Oce ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Flag Hill (Houtman Abrolhos)
Flag Hill is the highest hill on East Wallabi Island, and the highest point in the Houtman Abrolhos, an archipelago off the coast of Western Australia. It is located in the north-east of the island;Australia 1:100000 Topographic Survey, Sheet 1641 (Edition 1): Wallabi its gazetted location is ,Gazetteer of Australia (1996). Belconnen, ACT: Australian Surveying and Land Information Group. but in fact it is located somewhat east of there at about . It is about 15 metres (50 ft) high. Although East Wallabi Island was extensively explored by survivors of the 1629 ''Batavia'' shipwreck, no records of that event refer specifically to Flag Hill. Accordingly, discovery of the hill is attributed to John Clements Wickham, Commander during the third voyage of HMS ''Beagle'', which surveyed East Wallabi Island in May 1840. Wickham's lieutenant, John Lort Stokes, later wrote: No explanation for the name "Flag Hill" was given. From the peak of Flag Hill, Wickham's party sighted an island ...

University Of Western Australia
The University of Western Australia (UWA) is a public research university in the Australian state of Western Australia. The university's main campus is in Perth, the state capital, with a secondary campus in Albany, Western Australia, Albany and various other facilities elsewhere. UWA was established in 1911 by an act of the Parliament of Western Australia and began teaching students two years later. It is the sixth-oldest university in Australia and was Western Australia's only university until the establishment of Murdoch University in 1973. Because of its age and reputation, UWA is classed one of the "sandstone universities", an informal designation given to the oldest university in each state. The university also belongs to several more formal groupings, including the Group of Eight (Australian universities), Group of Eight and the Matariki Network of Universities. In recent years, UWA has generally been ranked either in the bottom half or just outside the University rankings ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Vertebrate
Vertebrates () comprise all animal taxa within the subphylum Vertebrata () ( chordates with backbones), including all mammals, birds, reptiles, amphibians, and fish. Vertebrates represent the overwhelming majority of the phylum Chordata, with currently about 69,963 species described. Vertebrates comprise such groups as the following: * jawless fish, which include hagfish and lampreys * jawed vertebrates, which include: ** cartilaginous fish (sharks, rays, and ratfish) ** bony vertebrates, which include: *** ray-fins (the majority of living bony fish) *** lobe-fins, which include: **** coelacanths and lungfish **** tetrapods (limbed vertebrates) Extant vertebrates range in size from the frog species ''Paedophryne amauensis'', at as little as , to the blue whale, at up to .

Percy Sladen Trust Expedition To The Abrolhos Islands
The Percy Sladen Trust Expeditions to the Abrolhos Islands were two scientific expeditions, conducted in 1913 and 1915 under the leadership of Professor William John Dakin and funded by the Percy Sladen Trust. These expeditions conducted extensive research into the natural history of the Houtman Abrolhos, an archipelago in the Indian Ocean off the coast of Western Australia. The first expedition lasted for three weeks from November 1913; the expedition members were Dakin and Wilfred Alexander. The pair undertook shore collecting, biological observations on various islands, some geological observations, and dredging in the lagoons and between the island groups. The resultant collections and observations were sufficiently important to warrant a second visit, and accordingly a second expedition was funded. The second expedition lasted for four weeks from October 1915; this time Dakin's companion was A. Cayzer. More hydrographic equipment was carried the second time, and a great deal of ...

Pigeon Island (Houtman Abrolhos)
Pigeon Island is a small island located need the middle of the Wallabi Group of the Houtman Abrolhos, an archipelago off the coast of Western Australia. It is almost entirely given over to western rock lobster fishers' camps, and as a result is far more disturbed than most other islands in the archipelago. A nearby island also seasonally populated by fishers is named Little Pigeon Island, hence Pigeon Island is sometimes referred to as "Big Pigeon Island". History The geographic location of Pigeon Island suggests that it might have been visited by survivors of the 1629 '' Batavia'' shipwreck, but there is no surviving evidence of this, either documentary or archaeological. It was mined for guano in the 20th century. Geography Pigeon Island is roughly triangular in shape, with a short side on the south west, and two long sides coming together at a point in the north east. The island is covered with infrastructure, with a high density of huts covering the entire island, right dow ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Angling
Angling is a fishing technique that uses a fish hook or "angle" (from Old English ''angol'') attached to a fishing line to tether individual fish in the mouth. The fishing line is usually manipulated via a fishing rod, although rodless techniques such as handlining and longlining also exist. Modern angling rods are usually fitted with a reel that functions as a cranking device for storing, retrieving and releasing out the line, although Tenkara fishing and cane pole fishing are two rod-angling methods that do not use any reel. The hook itself can be additionally weighted with a dense tackle called a sinker, and is typically dressed with an appetizing bait to attract the fish and enticing it into swallowing the hook, but sometimes an inedible fake bait with multiple attached hooks (known as a lure) is used instead of a single hook with edible bait. A bite indicator, such as a float or a quiver tip, is often used to relay underwater status of the hook to the surface. When ...

Crayfish
Crayfish are freshwater crustaceans belonging to the clade Astacidea, which also contains lobsters. In some locations, they are also known as crawfish, craydids, crawdaddies, crawdads, freshwater lobsters, mountain lobsters, rock lobsters, mudbugs, baybugs or yabbies. Taxonomically, they are members of the superfamilies Astacoidea and Parastacoidea. They breathe through feather-like gills. Some species are found in brooks and streams, where fresh water is running, while others thrive in swamps, ditches, and paddy fields. Most crayfish cannot tolerate polluted water, although some species, such as ''Procambarus clarkii'', are hardier. Crayfish feed on animals and plants, either living or decomposing, and detritus. The term "crayfish" is applied to saltwater species in some countries. Terminology The name "crayfish" comes from the Old French word ' (Modern French '). The word has been modified to "crayfish" by association with "fish" (folk etymology). The largely American ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
