Lake Walyungup
Lake Walyungup is a shallow saline lake in the suburbs of Warnbro and Port Kennedy, located south of the central business district of Perth, the capital of Western Australia. It is part of Rockingham Lakes Regional Park. In the local Nyungar language, Walyungup means "place where Noongars talk". Overview The lake is popular with land sailors, and is bound in the north by Safety Bay Road, in the east by Mandurah Road and in the west by the Mandurah railway line, with the Warnbro railway station bordering the north-western corner of the lake. North of Safety Bay Road, Lake Cooloongup is located. The lake, situated on an Holocene beach ridge, was once connected to the sea and was formed approximately 6,000 to 7,000 years ago. Within the lake, Holocene nonmarine microbial structures, reported as either stromatolites or thrombolites, have been found. Like Lake Cooloongup, Lake Walyungup is thought to be drying because of reduced rainfalls. Depths of both lakes fluctuate from as ...

Thrombolite
Thrombolites (from Ancient Greek θρόμβος ''thrómbos'' meaning " clot" and λῐ́θος ''líthos'' meaning "stone") are clotted accretionary structures formed in shallow water by the trapping, binding, and cementation of sedimentary grains by biofilms of microorganisms, especially cyanobacteria. Structures Thrombolites have a clotted structure without the laminae of stromatolites. Each clot within a thrombolite mound is a separate cyanobacterial colony. The clots are on the scale of millimetres to centimetres and may be interspersed with sand, mud or sparry carbonate. Clots that make up thrombolites are called thromboids to avoid confusion with other clotted textures. The larger clots make up more than 40% of a thrombolite's volume and each clot has a complex internal structure of cells and rimmed lobes resulting primarily from calcification of the cyanobacterial colony. Very little sediment is found within the clots because the main growth method is calcification r ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Warnbro Railway Station
Warnbro railway station is a commuter railway station in Warnbro, a suburb of Perth, Western Australia. It is on the Mandurah line, which is part of the Transperth commuter rail network, and is located immediately south-east of the interchange of Safety Bay Road and Ennis Avenue. It has two side platforms, linked by a pedestrian overpass accessed by stairs, a lift, and escalators. Services run every 10 minutes during peak, and every 15 minutes between peak.

Banksia Littoralis
''Banksia littoralis'', commonly known as the swamp banksia, swamp oak, river banksia or seaside banksia and the western swamp banksia, is a species of tree that is Endemism, endemic to the south-west of Western Australia. The Noongar peoples know the plant as pungura, boongura or gwangia. It has rough, crumbly bark, linear, more or less serrated leaves arranged in Whorl (botany), whorls, yellow flowers and up to two hundred Follicle (fruit), follicles in each head. Description ''Banksia littoralis'' is a tree that typically grows up to around , sometimes to , with rough, crumbly bark and woolly-hairy stems. The leaves are arranged in whorls and are linear in shape, usually serrated in the upper half, long and wide on a Petiole (botany), petiole long. The flowers are arranged on a cylindrical head long and wide when the flowers open. The flowers are yellow with a perianth long and a hooked Gynoecium#Pistils, pistil long.

Canopy (biology)
In biology, the canopy is the aboveground portion of a plant cropping or crop, formed by the collection of individual plant crowns. In forest ecology, canopy also refers to the upper layer or habitat zone, formed by mature tree crowns and including other biological organisms ( epiphytes, lianas, arboreal animals, etc.). The communities that inhabit the canopy layer are thought to be involved in maintaining forest diversity, resilience, and functioning. Sometimes the term canopy is used to refer to the extent of the outer layer of leaves of an individual tree or group of trees. Shade trees normally have a dense canopy that blocks light from lower growing plants. Observation Early observations of canopies were made from the ground using binoculars or by examining fallen material. Researchers would sometimes erroneously rely on extrapolation by using more reachable samples taken from the understory. In some cases, they would use unconventional methods such as chairs susp ...

Eucalyptus Gomphocephala
''Eucalyptus gomphocephala'', known as tuart, is a species of tree, one of the six forest giants of Southwest Australia. Tuart forest was common on the Swan coastal plain, until the valuable trees were felled for export and displaced by the urban development around Perth, Western Australia. The wood is dense, hard, water resistant and resists splintering, and found many uses when it was available. Remnants of tuart forest occur in state reserves and parks, the tree has occasionally been introduced to other regions of Australia and overseas. Remaining trees are vulnerable to phytophthora dieback, an often fatal disorder, including a previously unknown species discovered during analysis of dead specimens. Description The tree is native to the southwest of Western Australia and typically grows to a height of . The tallest known living Tuart is 47m tall and located in the Tuart Forest NP near Ludlow. The largest Tuart tree has a wood volume of 108m³. Taller trees are often found a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
World War II
World War II or the Second World War, often abbreviated as WWII or WW2, was a world war that lasted from 1939 to 1945. It involved the vast majority of the world's countries—including all of the great powers—forming two opposing military alliances: the Allies and the Axis powers. World War II was a total war that directly involved more than 100 million personnel from more than 30 countries. The major participants in the war threw their entire economic, industrial, and scientific capabilities behind the war effort, blurring the distinction between civilian and military resources. Aircraft played a major role in the conflict, enabling the strategic bombing of population centres and deploying the only two nuclear weapons ever used in war. World War II was by far the deadliest conflict in human history; it resulted in 70 to 85 million fatalities, mostly among civilians. Tens of millions died due to genocides (including the Holocaust), starvation, ma ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Wagyl
The Wagyl (also written Waugal and Waagal and variants) is the Noongar manifestation of the Rainbow Serpent in Australian Aboriginal mythology, from the culture based around the south-west of Western Australia. The Noongar describe the Wagyl as a snakelike Dreaming creature responsible for the creation of the Swan and Canning rivers and other waterways and landforms around present day Perth and the south-west of Western Australia. The Wagyl created many local landscape features between the Porongarups and off the coast of Fremantle. Indeed, Porongarup means 'spirit gathering place', from the Noongar nys , Borong , lit=Spirit , label=none, nys , Gar , lit=Gathering , label=none and nys , Up , lit=Place , label=none. The Wagyl was delegated to protect the rivers, lakes, springs and the wildlife, and Wagyl sacred sites tend to be natural sun-traps, located beside bodies of water. The Noongar people were appointed by the Wagyl as the guardians of the land, and the Wagyl was ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Evapotranspiration
Evapotranspiration (ET) is the combined processes by which water moves from the earth’s surface into the atmosphere. It covers both water evaporation (movement of water to the air directly from soil, canopies, and water bodies) and transpiration (movement of water from the soil, through roots and bodies of vegetation, on leaves and then into the air). Evapotranspiration is an important part of the local water cycle and climate, as well as measurement of it plays a key role in agricultural irrigation and water resource management. Definition Evapotranspiration is a combination of evaporation and transpiration, measured in order to better understand crop water requirements, irrigation scheduling, and watershed management. The two key components of evapotranspiration are: * Evaporation: the movement of water directly to the air from sources such as the soil and water bodies. It can be affected by factors including heat, humidity, and wind speed. * Transpiration: the move ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
