Columba Bollii
Bolle's pigeon (''Columba bollii'') is a species of the genus Columba of family Columbidae, doves and pigeons, endemic to the Canary Islands, Spain. This bird is named after the German naturalist Carl Bolle, who was the first to distinguish it from the laurel pigeon. This wood pigeon is endemic to the laurel forest habitat. Description Larger than the common pigeon, a length of 36 cm to 38 cm. It is a large dark grey pigeon. At 37–40 cm, it looks like a very dark wood pigeon. Its dark grey, rather than brown, plumage and the dark bands on the grey tail distinguish it from the other pigeon endemic to the Canary Islands, the laurel pigeon. It is a basically dark grey bird, with a pinkish breast. It lacks any white markings, which together with its darker plumage distinguishes it from the other species. With red beak, most intense at the tip. Head relatively large, slate gray, in males, with bluish or greenish metallic side of the neck and back of neck. Eyes round ...

Frederick DuCane Godman
Frederick DuCane Godman DCL FRS FLS FGS FRGS FES FZS MRI FRHS (15 January 1834 – 19 February 1919) was an English lepidopterist, entomologist and ornithologist. He was one of the twenty founding members of the British Ornithologists' Union. Along with Osbert Salvin, he is remembered for studying the fauna and flora of Central America. Godman collected Iznik, Hispano-Moresque and early Iranian pottery. His collection of more than 600 pieces was donated to the British Museum through the will of his younger daughter, Catherine, who died in 1982. Early life and Cambridge years Frederick DuCane Godman was born on 15 January 1834 at Park Hatch, Godalming, Surrey, and was one of the thirteen children of Joseph Godman and Caroline Smith. Joseph Godman was a partner in the brewery firm Whitbread & Company. Frederick was sent to study at Eton College in 1844 but left three years later due to poor health and was educated at home by private tutors. At the age of 18 he went with hi ...

Persea Indica
''Persea indica'' is a large, evergreen tree in the laurel family (Lauraceae), native to humid uplands on Madeira and the Canary Islands in the North Atlantic. It belongs to the genus ''Persea'', a group of evergreen trees including the avocado. It is threatened by habitat loss. It has been introduced to a number of islands in the nearby Azores. Overview The family Lauraceae was part of Gondwanaland flora. There they spread over most of the continent. The genus ''Persea'' died out in increasingly xerophytic Africa, starting with the freezing of Antarctica about 20 million years ago and the formation of the Benguela current. The genus is Local extinction, extinct in Africa, save for ''P. indica'', which survives in the fog shrouded mountains of the Canary Islands, which with Madagascar, constitute Africa's Laurel forest plant refugia. Fossil evidence indicates that the genus originated in West Africa during the Paleocene, and spread to Asia, to South America, and to Europe and ...

Habitats Directive
The Habitats Directive (more formally known as Council Directive 92/43/EEC on the Conservation of natural habitats and of wild fauna and flora) is a directive adopted by the European Community in 1992 as a response to the Berne Convention. The European Community was reformed as the European Union the following year, but the directive is still recognised. The Habitats Directive required national governments to specify areas that are expected to be ensuring the conservation of flora and fauna species. This led to the setting up of a network of protected areas across the EU, along with ' Special Areas of Conservation', which together with the existing Special Protection Areas, became the so-called Natura 2000 network established to protect species and habitats. This directive is one of the main pillars of the European Union's system of wildlife and nature conservation, another being the Birds Directive. The Habitats Directive, together with the Birds Directive, are also called th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Birds Directive
The Birds Directive (formally known as Council Directive 2009/147/EC on the conservation of wild birds) is the oldest piece of EU legislation on the environment and one of its cornerstones which was unanimously adopted in April 1979 as the Directive 79/409/EEC. Amended in 2009, it became the Directive 2009/147/EC. It aims to protect all European wild birds and the habitats of listed species, in particular through the designation of Special Protection Areas (often known by the acronym SPA). The Birds Directive is one of the EU's two directives in relation to wildlife and nature conservation, the other being the Habitats Directive. The Habitats Directive led to the setting up of a network of Special Areas of Conservation, which together with the existing Special Protection Areas form a network of protected sites across the European Union called Natura 2000. In the UK the Directive is implemented by the Wildlife and Countryside Act 1981. See also * Conservation movement * List of ...

European Union
The European Union (EU) is a supranational political and economic union of member states that are located primarily in Europe. The union has a total area of and an estimated total population of about 447million. The EU has often been described as a '' sui generis'' political entity (without precedent or comparison) combining the characteristics of both a federation and a confederation. Containing 5.8per cent of the world population in 2020, the EU generated a nominal gross domestic product (GDP) of around trillion in 2021, constituting approximately 18per cent of global nominal GDP. Additionally, all EU states but Bulgaria have a very high Human Development Index according to the United Nations Development Programme. Its cornerstone, the Customs Union, paved the way to establishing an internal single market based on standardised legal framework and legislation that applies in all member states in those matters, and only those matters, where the states have agreed to act ...

Threatened Species
Threatened species are any species (including animals, plants and fungi) which are vulnerable to endangerment in the near future. Species that are threatened are sometimes characterised by the population dynamics measure of ''critical depensation'', a mathematical measure of biomass related to population growth rate. This quantitative metric is one method of evaluating the degree of endangerment. IUCN definition The International Union for Conservation of Nature (IUCN) is the foremost authority on threatened species, and treats threatened species not as a single category, but as a group of three categories, depending on the degree to which they are threatened: *Vulnerable species *Endangered species * Critically endangered species Less-than-threatened categories are near threatened, least concern, and the no longer assigned category of conservation dependent. Species which have not been evaluated (NE), or do not have sufficient data ( data deficient) also are not considered ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
IUCN Red List
The International Union for Conservation of Nature (IUCN) Red List of Threatened Species, also known as the IUCN Red List or Red Data Book, founded in 1964, is the world's most comprehensive inventory of the global conservation status of biological species. It uses a set of precise criteria to evaluate the extinction risk of thousands of species and subspecies. These criteria are relevant to all species and all regions of the world. With its strong scientific base, the IUCN Red List is recognized as the most authoritative guide to the status of biological diversity. A series of Regional Red Lists are produced by countries or organizations, which assess the risk of extinction to species within a political management unit. The aim of the IUCN Red List is to convey the urgency of conservation issues to the public and policy makers, as well as help the international community to reduce species extinction. According to IUCN the formally stated goals of the Red List are to provi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Least Concern
A least-concern species is a species that has been categorized by the International Union for Conservation of Nature (IUCN) as evaluated as not being a focus of species conservation because the specific species is still plentiful in the wild. They do not qualify as threatened, near threatened, or (before 2001) conservation dependent. Species cannot be assigned the "Least Concern" category unless they have had their population status evaluated. That is, adequate information is needed to make a direct, or indirect, assessment of its risk of extinction based on its distribution or population status. Evaluation Since 2001 the category has had the abbreviation "LC", following the IUCN 2001 Categories & Criteria (version 3.1). Before 2001 "least concern" was a subcategory of the "Lower Risk" category and assigned the code "LR/lc" or lc. Around 20% of least concern taxa (3261 of 15636) in the IUCN database still use the code "LR/lc", which indicates they have not been re-evaluate ...

Black Rat
The black rat (''Rattus rattus''), also known as the roof rat, ship rat, or house rat, is a common long-tailed rodent of the stereotypical rat genus ''Rattus'', in the subfamily Murinae. It likely originated in the Indian subcontinent, but is now found worldwide. The black rat is black to light brown in colour with a lighter underside. It is a generalist omnivore and a serious pest to farmers because it feeds on a wide range of agricultural crops. It is sometimes kept as a pet. In parts of India, it is considered sacred and respected in the Karni Mata Temple in Deshnoke. Taxonomy ''Mus rattus'' was the scientific name proposed by Carl Linnaeus in 1758 for the black rat. Three subspecies were once recognized, but today are considered invalid and are now known to be actually color morphs: *''Rattus rattus rattus'' – roof rat *''Rattus rattus alexandrinus'' – Alexandrine rat *''Rattus rattus frugivorus'' – fruit rat Characteristics A typical adult black rat is long, n ...

Secondary Growth
In botany, secondary growth is the growth that results from cell division in the cambia or lateral meristems and that causes the stems and roots to thicken, while primary growth is growth that occurs as a result of cell division at the tips of stems and roots, causing them to elongate, and gives rise to primary tissue. Secondary growth occurs in most seed plants, but monocots usually lack secondary growth. If they do have secondary growth, it differs from the typical pattern of other seed plants. The formation of secondary vascular tissues from the cambium is a characteristic feature of dicotyledons and gymnosperms. In certain monocots, the vascular tissues are also increased after the primary growth is completed but the cambium of these plants is of a different nature. In the living pteridophytes this feature is extremely rare, only occurring in ''Isoetes''. Lateral meristems In many vascular plants, secondary growth is the result of the activity of the two lateral meriste ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Old-growth Forest
An old-growth forestalso termed primary forest, virgin forest, late seral forest, primeval forest, or first-growth forestis a forest that has attained great age without significant disturbance, and thereby exhibits unique ecological features, and might be classified as a climax community. The Food and Agriculture Organization of the United Nations defines primary forests as naturally regenerated forests of native tree species where there are no clearly visible indications of human activity and the ecological processes are not significantly disturbed. More than one-third (34 percent) of the world's forests are primary forests. Old-growth features include diverse tree-related structures that provide diverse wildlife habitat that increases the biodiversity of the forested ecosystem. Virgin or first-growth forests are old-growth forests that have never been logged. The concept of diverse tree structure includes multi-layered canopies and canopy gaps, greatly varying tree height ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
