Chek Jawa
Tanjong Chek Jawa (or Tanjung Chek Jawa or simply Chek Jawa) is a cape and the name of its 100-hectare wetlands located on the south-eastern tip of Pulau Ubin, an island off the north-eastern coast of the main island of Singapore. Chek Jawa is among the last few places left in Singapore with a natural rocky shore. The wetlands are unique as several ecosystems can be observed in one area – sandy beach, rocky beach, seagrass lagoon, coral rubble, mangroves and coastal forest. The site forms part of the Ubin–Khatib Important Bird Area (IBA), identified as such by BirdLife International because it supports significant numbers of visiting and resident birds, some of which are threatened. In December 2001, the government called off reclamation plans of the Chek Jawa area after a biodiversity survey conducted by conservationist volunteers. State use of the land will be deferred for the next 10 years. However, Chek Jawa may still be re-used by the government in and after 2012. Hist ...

Biodiversity
Biodiversity or biological diversity is the variety and variability of life on Earth. Biodiversity is a measure of variation at the genetic (''genetic variability''), species (''species diversity''), and ecosystem (''ecosystem diversity'') level. Biodiversity is not distributed evenly on Earth; it is usually greater in the tropics as a result of the warm climate and high primary productivity in the region near the equator. Tropical forest ecosystems cover less than 10% of earth's surface and contain about 90% of the world's species. Marine biodiversity is usually higher along coasts in the Western Pacific, where sea surface temperature is highest, and in the mid-latitudinal band in all oceans. There are latitudinal gradients in species diversity. Biodiversity generally tends to cluster in hotspots, and has been increasing through time, but will be likely to slow in the future as a primary result of deforestation. It encompasses the evolutionary, ecological, and cultural ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Seastar
Starfish or sea stars are star-shaped echinoderms belonging to the class Asteroidea (). Common usage frequently finds these names being also applied to ophiuroids, which are correctly referred to as brittle stars or basket stars. Starfish are also known as asteroids due to being in the class Asteroidea. About 1,900 species of starfish live on the seabed in all the world's oceans, from warm, tropical zones to frigid, polar regions. They are found from the intertidal zone down to abyssal depths, at below the surface. Starfish are marine invertebrates. They typically have a central disc and usually five arms, though some species have a larger number of arms. The aboral or upper surface may be smooth, granular or spiny, and is covered with overlapping plates. Many species are brightly coloured in various shades of red or orange, while others are blue, grey or brown. Starfish have tube feet operated by a hydraulic system and a mouth at the centre of the oral or lower surface. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Sea Anemone
Sea anemones are a group of predation, predatory marine invertebrates of the order (biology), order Actiniaria. Because of their colourful appearance, they are named after the ''Anemone'', a terrestrial flowering plant. Sea anemones are classified in the phylum Cnidaria, class Anthozoa, subclass Hexacorallia. As cnidarians, sea anemones are related to corals, jellyfish, tube-dwelling anemones, and ''hydra (genus), Hydra''. Unlike jellyfish, sea anemones do not have a Jellyfish#Life history and behavior, medusa stage in their life cycle. A typical sea anemone is a single polyp (zoology), polyp attached to a hard surface by its base, but some species live in soft sediment, and a few float near the surface of the water. The polyp has a columnar trunk topped by an oral disc with a ring of tentacles and a central mouth. The tentacles can be retracted inside the body cavity or expanded to catch passing prey. They are armed with cnidocytes (stinging cells). In many species, additional n ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Seawater
Seawater, or salt water, is water from a sea or ocean. On average, seawater in the world's oceans has a salinity of about 3.5% (35 g/L, 35 ppt, 600 mM). This means that every kilogram (roughly one liter by volume) of seawater has approximately of dissolved salts (predominantly sodium () and chloride () ions). The average density at the surface is 1.025 kg/L. Seawater is denser than both fresh water and pure water (density 1.0 kg/L at ) because the dissolved salts increase the mass by a larger proportion than the volume. The freezing point of seawater decreases as salt concentration increases. At typical salinity, it freezes at about . The coldest seawater still in the liquid state ever recorded was found in 2010, in a stream under an Antarctic glacier: the measured temperature was . Seawater pH is typically limited to a range between 7.5 and 8.4. However, there is no universally accepted reference pH-scale for seawater and the difference between measurement ...

Freshwater
Fresh water or freshwater is any naturally occurring liquid or frozen water containing low concentrations of dissolved salts and other total dissolved solids. Although the term specifically excludes seawater and brackish water, it does include non- salty mineral-rich waters such as chalybeate springs. Fresh water may encompass frozen and meltwater in ice sheets, ice caps, glaciers, snowfields and icebergs, natural precipitations such as rainfall, snowfall, hail/ sleet and graupel, and surface runoffs that form inland bodies of water such as wetlands, ponds, lakes, rivers, streams, as well as groundwater contained in aquifers, subterranean rivers and lakes. Fresh water is the water resource that is of the most and immediate use to humans. Water is critical to the survival of all living organisms. Many organisms can thrive on salt water, but the great majority of higher plants and most insects, amphibians, reptiles, mammals and birds need fresh water to survive. Fresh wa ...

Spring Tide
Tides are the rise and fall of sea levels caused by the combined effects of the gravitational forces exerted by the Moon (and to a much lesser extent, the Sun) and are also caused by the Earth and Moon orbiting one another. Tide tables can be used for any given locale to find the predicted times and amplitude (or " tidal range"). The predictions are influenced by many factors including the alignment of the Sun and Moon, the phase and amplitude of the tide (pattern of tides in the deep ocean), the amphidromic systems of the oceans, and the shape of the coastline and near-shore bathymetry (see '' Timing''). They are however only predictions, the actual time and height of the tide is affected by wind and atmospheric pressure. Many shorelines experience semi-diurnal tides—two nearly equal high and low tides each day. Other locations have a diurnal tide—one high and low tide each day. A "mixed tide"—two uneven magnitude tides a day—is a third regular category. Tide ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Tour Guide
A tour guide (U.S.) or a tourist guide (European) is a person who provides assistance, information on cultural, historical and contemporary heritage to people on organized sightseeing and individual clients at educational establishments, religious and historical sites such as; museums, and at various venues of tourist attraction resorts. Tour guides also take clients on outdoor guided trips. These trips include hiking, whitewater rafting, mountaineering, alpine climbing, rock climbing, ski and snowboarding in the backcountry, fishing, and biking. History In 18th-century Japan, a traveler could pay for a tour guide or consult guide books such as Kaibara Ekken's ''Keijō Shōran'' (The Excellent Views of Kyoto). Description In Europe The CEN (European Committee for Standardization) definition for "tourist guide" – part of the work by CEN on definitions for terminology within the tourism industry – is a "person who guides visitors in the language of their choice a ...

National Parks Board
The National Parks Board (NParks) is a statutory board under the Ministry of National Development of the Government of Singapore. History In November 1989, Minister of National Development, S. Dhanabalan, presented the National Parks Bill in Parliament to form a body to manage the three parks, Singapore Botanic Gardens, Fort Canning Park and Bukit Timah Nature Reserve, in Singapore. In March 1990, Minister of State for National Development, Lee Boon Yang introduced the National Parks Bill in Parliament to form the National Parks Board as a statutory board. On 6 June 1990, the National Parks Board was formed to manage the three parks. On 1 July 1996, the Parks and Recreation Department was merged with the National Parks Board. Since 1 April 2019, all non-food plant and animal-related functions originally under the Agri-Food and Veterinary Authority of Singapore were transferred to NParks under Animal and Veterinary Service (AVS) as part of a reorganisation.

Habitat Conservation
Habitat conservation is a management practice that seeks to conserve, protect and restore habitats and prevent species extinction, fragmentation or reduction in range. It is a priority of many groups that cannot be easily characterized in terms of any one ideology. History of the conservation movement For much of human history, ''nature'' was seen as a resource that could be controlled by the government and used for personal and economic gain. The idea was that plants only existed to feed animals and animals only existed to feed humans. The value of land was limited only to the resources it provided such as fertile soil, timber, and minerals. Throughout the 18th and 19th centuries, social views started to change and conservation principles were first practically applied to the forests of British India. The conservation ethic that began to evolve included three core principles: 1) human activities damage the environment, 2) there was a civic duty to maintain the environment ...

Singapore Government
The Government of Singapore is defined by the Constitution of Singapore to mean the executive branch of the state, which is made up of the president and the Cabinet. Although the president acts in their personal discretion in the exercise of certain functions as a check on the Cabinet and the Parliament, their role is largely ceremonial. It is the Cabinet, composed of the prime minister and other ministers appointed on their advice by the president, that have the general direction and control of the government. The Cabinet is formed by the political party that gains a simple majority in each general election. A statutory board is an autonomous agency of the Government that is established by an Act of Parliament and overseen by a government ministry. Unlike ministries and government departments that are subdivisions of ministries, statutory boards are not staffed by civil servants and have greater independence and flexibility in their operations. There are five Community De ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
