People's Trust For Endangered Species
Peoples Trust for Endangered Species (PTES) is a charitable organisation registered in England and Wales. It exists to promote the conservation of rare or declining species and habitats in the UK and worldwide through environmental monitoring, monitoring, public engagement, education, and through the funding of Habitat conservation, conservation projects and research. It also owns and manages two nature reserves. As of April 2015, PTES has 16 employees, five trustees and coordinates around 24,000 volunteering, volunteers in the UK. PTES relies on donations from the general public and grants from trusts and Foundation (non-profit), foundations to continue its work - it receives no core funding from the UK Government. The organisation has registered charity number 274206. History PTES was founded in 1977. Originally based in South Kensington at Imperial College London, in 1993 the organisation moved to its present location in Battersea, south-west London. In 2001 PTES developed Mam ...

Charitable Organization
A charitable organization or charity is an organization whose primary objectives are philanthropy and social well-being (e.g. educational, Religion, religious or other activities serving the public interest or common good). The legal definition of a charitable organization (and of charity) varies between countries and in some instances regions of the country. The Charity regulators, regulation, the tax treatment, and the way in which charity law affects charitable organizations also vary. Charitable organizations may not use any of their funds to profit individual persons or entities. (However, some charitable organizations have come under scrutiny for spending a disproportionate amount of their income to pay the salaries of their leadership). Financial figures (e.g. tax refund, revenue from fundraising, revenue from sale of goods and services or revenue from investment) are indicators to assess the financial sustainability of a charity, especially to charity evaluators.

South Kensington
South Kensington, nicknamed Little Paris, is a district just west of Central London in the Royal Borough of Kensington and Chelsea. Historically it settled on part of the scattered Middlesex village of Brompton. Its name was supplanted with the advent of the railways in the late 19th century and the opening (and shutting) and naming of local tube stations. The area has many museums and cultural landmarks with a high number of visitors, such as the Natural History Museum, the Science Museum and the Victoria and Albert Museum. Adjacent affluent centres such as Knightsbridge, Chelsea and Kensington, have been considered as some of the most exclusive real estate in the world. Geography As is often the case in other areas of London, the boundaries for South Kensington are arbitrary and have altered with time. This is due in part to usage arising from the tube stops and other landmarks which developed across Brompton. A contemporary definition is the commercial area around the Sout ...

Populations Of Species
This is a collection of lists of organisms by their population. While most of the numbers are estimates, they have been made by the experts in their fields. Species population is a science falling under the purview of population ecology and biogeography. Individuals are counted by census, as carried out for the piping plover; using the transect method, as done for the mountain plover; and beginning in 2012 by satellite, with the emperor penguin being first subject counted in this manner. Number of species More than 99 percent of all species, amounting to over five billion species, that ever lived on Earth are estimated to be extinct. Estimates on the number of Earth's current species range from 10 million to 14 million, of which about 1.2 million have been documented and over 86 percent have not yet been described. According to another study, the number of described species has been estimated at 1,899,587. 2000–2009 saw approximately 17,000 species described per year. The total ...

European Water Vole
The European water vole or northern water vole (''Arvicola amphibius''), is a semi-aquatic rodent. It is often informally called the water rat, though it only superficially resembles a true rat. Water voles have rounder noses than rats, deep brown fur, chubby faces and short fuzzy ears; unlike rats their tails, paws and ears are covered with hair. In the wild, on average, water voles only live about five months. Maximum longevity in captivity is two and a half years. Appearance Water voles reach in length, plus a tail which is about half the length of the body. Weights reported for adults are variable. It is possible for large, optimal adults to weigh as much as However, these are peak weights. Elsewhere, the mean body mass has been reported as , although this figure includes immature water voles. The minimum weight to successfully breed as well as to survive winter is reportedly in females and in males.Yavuz, Güliz, Ercüment Çolak, and Teoman Kankılıç. ''Investig ...

European Hedgehog
The European hedgehog (''Erinaceus europaeus''), also known as the West European hedgehog or common hedgehog, is a hedgehog species native to Europe from Iberia and Italy northwards into Scandinavia and westwards into the British Isles.Harris, S. & Yalden, D.W. (2008). ''Mammals of the British Isles: Handbook, 4th Edition.'' The Mammal Society, Southampton. It is a generally common and widely distributed species that can survive across a wide range of habitat types. It is a well-known species, and a favourite in European gardens, both for its endearing appearance and its preference for eating a range of garden pests. While populations are currently stable across much of its range, it is declining severely in Great Britain where it is now Red Listed (classified as near to extinction). Outside its native range, the species was introduced to New Zealand during the late-19th and early-20th centuries. Description The European hedgehog has a generalised body structure with unspeciali ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Hazel Dormouse
The hazel dormouse or common dormouse (''Muscardinus avellanarius'') is a small mammal and the only living species in the genus ''Muscardinus''. Distribution and habitat The hazel dormouse is native to northern Europe and Asia Minor. It is the only dormouse native to the British Isles, and is therefore often referred to simply as the "dormouse" in British sources, although the edible dormouse, ''Glis glis'', has been accidentally introduced and now has an established population in South East England. Though Ireland has no native dormouse, the hazel dormouse was discovered in County Kildare in 2010, and appears to be spreading rapidly, helped by the prevalence of hedgerows in the Irish countryside. The United Kingdom distribution of the hazel dormouse can be found on theNational Biodiversity Network website A 2020 study found that hazel dormice in Britain have declined by 51% since 2000. Woodland habitat loss and management and a warming climate are seen as material threats to th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Conservation Biology
Conservation biology is the study of the conservation of nature and of Earth's biodiversity with the aim of protecting species, their habitats, and ecosystems from excessive rates of extinction and the erosion of biotic interactions. It is an interdisciplinary subject drawing on natural and social sciences, and the practice of natural resource management. The conservation ethic is based on the findings of conservation biology. Origins The term conservation biology and its conception as a new field originated with the convening of "The First International Conference on Research in Conservation Biology" held at the University of California, San Diego in La Jolla, California, in 1978 led by American biologists Bruce A. Wilcox and Michael E. Soulé with a group of leading university and zoo researchers and conservationists including Kurt Benirschke, Sir Otto Frankel, Thomas Lovejoy, and Jared Diamond. The meeting was prompted due to concern over tropical deforestation, disappearin ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Earth
Earth is the third planet from the Sun and the only astronomical object known to harbor life. While large volumes of water can be found throughout the Solar System, only Earth sustains liquid surface water. About 71% of Earth's surface is made up of the ocean, dwarfing Earth's polar ice, lakes, and rivers. The remaining 29% of Earth's surface is land, consisting of continents and islands. Earth's surface layer is formed of several slowly moving tectonic plates, which interact to produce mountain ranges, volcanoes, and earthquakes. Earth's liquid outer core generates the magnetic field that shapes the magnetosphere of the Earth, deflecting destructive solar winds. The atmosphere of the Earth consists mostly of nitrogen and oxygen. Greenhouse gases in the atmosphere like carbon dioxide (CO2) trap a part of the energy from the Sun close to the surface. Water vapor is widely present in the atmosphere and forms clouds that cover most of the planet. More solar e ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Species
In biology, a species is the basic unit of classification and a taxonomic rank of an organism, as well as a unit of biodiversity. A species is often defined as the largest group of organisms in which any two individuals of the appropriate sexes or mating types can produce fertile offspring, typically by sexual reproduction. Other ways of defining species include their karyotype, DNA sequence, morphology, behaviour or ecological niche. In addition, paleontologists use the concept of the chronospecies since fossil reproduction cannot be examined. The most recent rigorous estimate for the total number of species of eukaryotes is between 8 and 8.7 million. However, only about 14% of these had been described by 2011. All species (except viruses) are given a two-part name, a "binomial". The first part of a binomial is the genus to which the species belongs. The second part is called the specific name or the specific epithet (in botanical nomenclature, also sometimes i ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Diversity Of Life
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 proce ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Natural Heritage
Natural heritage refers to the sum total of the elements of biodiversity, including flora and fauna, ecosystems and geological structures. It forms part of our natural resources. Definition Heritage is that which is ''inherited'' from past generations, maintained in the present, and bestowed to future generations. The term "natural heritage", derived from "natural inheritance", pre-dates the term "biodiversity". It is a less scientific term and more easily comprehended in some ways by the wider audience interested in conservation. The term was used in this context in the United States when Jimmy Carter set up the Georgia Heritage Trust while he was governor of Georgia; Carter's trust dealt with both natural and cultural heritage. It would appear that Carter picked the term up from Lyndon Johnson, who used it in a 1966 Message to Congress. (He may have gotten the term from his wife Lady Bird Johnson who was personally interested in conservation.) President Johnson signed the W ...

Mammals
Mammals () are a group of vertebrate animals constituting the class Mammalia (), characterized by the presence of mammary glands which in females produce milk for feeding (nursing) their young, a neocortex (a region of the brain), fur or hair, and three middle ear bones. These characteristics distinguish them from reptiles (including birds) from which they diverged in the Carboniferous, over 300 million years ago. Around 6,400 extant species of mammals have been described divided into 29 orders. The largest orders, in terms of number of species, are the rodents, bats, and Eulipotyphla (hedgehogs, moles, shrews, and others). The next three are the Primates (including humans, apes, monkeys, and others), the Artiodactyla ( cetaceans and even-toed ungulates), and the Carnivora (cats, dogs, seals, and others). In terms of cladistics, which reflects evolutionary history, mammals are the only living members of the Synapsida (synapsids); this clade, together with Saur ...
