Ruff (bird)
The ruff (''Calidris pugnax'') is a medium-sized wading bird that breeds in marshes and wet meadows across northern Eurasia. This highly gregarious sandpiper is migratory and sometimes forms huge flocks in its winter grounds, which include southern and western Europe, Africa, southern Asia and Australia. The ruff is a long-necked, pot-bellied bird. This species shows marked sexual dimorphism; the male is much larger than the female (the reeve), and has a breeding plumage that includes brightly coloured head tufts, bare orange facial skin, extensive black on the breast, and the large collar of ornamental feathers that inspired this bird's English name. The female and the non-breeding male have grey-brown upperparts and mainly white underparts. Three differently plumaged types of male, including a rare form that mimics the female, use a variety of strategies to obtain mating opportunities at a lek, and the colourful head and neck feathers are erected as part of the elaborate ...

Diergaarde Blijdorp
(; ), officially Rotterdam Zoo, is a zoo located in the northwestern part of Rotterdam. It is one of the oldest zoos in the Netherlands, and has been operated by the ("Royal Rotterdam Zoo Foundation"). Divided into several zoogeographic regions, the Blijdorp Zoo boasts 562 species. It also has a shop, multiple cafes, and an information centre. The zoo is a member of the Dutch Zoo Federation and the European Association of Zoos and Aquaria. In 2007, it celebrated its 150th anniversary. History In 1855, a garden was set up for pheasants and waterfowl in the center of Rotterdam, near the Kruiskade. It was a success and on May 18, 1857, the 'Rotterdamsche Diergaarde' was opened as a sequel. The first director was the animal trainer Henri Martin. The same year the 'Vereniging Rotterdamsche Diergaarde' was founded. In 1932 it was decided to reorganize the zoo. In 1937 it was decided to move the zoo to a new location. The zoo exchanged land with the municipality: the municipali ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Stoat
The stoat (''Mustela erminea''), also known as the Eurasian ermine or ermine, is a species of mustelid native to Eurasia and the northern regions of North America. Because of its wide circumpolar distribution, it is listed as Least Concern on the IUCN Red List. The name ermine () is used especially in its pure white winter coat of the stoat or its fur. Ermine fur was used in the 15th century by Catholic monarchs, who sometimes used it as the mozzetta cape. It has long been used on the ceremonial robes of members of the United Kingdom House of Lords. It was also used in capes on images such as the Infant Jesus of Prague. The stoat was introduced into New Zealand in the late 19th century to control rabbits. However, they have had a devastating effect on native bird populations; as such, the species was nominated as one of the world's top 100 "worst invaders". Etymology The root word for "stoat" is likely either the Dutch word ("bold") or the Gothic word (, "to push"). Accor ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Natural History
Natural history is a domain of inquiry involving organisms, including animals, fungi, and plants, in their natural environment, leaning more towards observational than experimental methods of study. A person who studies natural history is called a naturalist or natural historian. Natural history encompasses scientific research but is not limited to it. It involves the systematic study of any category of natural objects or organisms, so while it dates from studies in the ancient Greco-Roman world and the mediaeval Arabic world, through to European Renaissance naturalists working in near isolation, today's natural history is a cross-discipline umbrella of many specialty sciences; e.g., geobiology has a strong multidisciplinary nature. Definitions Before 1900 The meaning of the English term "natural history" (a calque of the Latin ''historia naturalis'') has narrowed progressively with time, while, by contrast, the meaning of the related term "nature" has widened (see also ...

Systema Naturae
' (originally in Latin written ' with the Orthographic ligature, ligature æ) is one of the major works of the Sweden, Swedish botanist, zoologist and physician Carl Linnaeus (1707–1778) and introduced the Linnaean taxonomy. Although the system, now known as binomial nomenclature, was partially developed by the Bauhin brothers, Gaspard Bauhin, Gaspard and Johann Bauhin, Johann, Linnaeus was the first to use it consistently throughout his book. The first edition was published in 1735. The full title of the 10th edition (1758), which was the most important one, was ', which appeared in English in 1806 with the title: "A General System of Nature, Through the Three Grand Kingdoms of Animals, Vegetables, and Minerals, Systematically Divided Into their Several Classes, Orders, Genera, Species, and Varieties, with their Habitations, Manners, Economy, Structure and Peculiarities".

Agreement On The Conservation Of African-Eurasian Migratory Waterbirds
The Agreement on the Conservation of African-Eurasian Migratory Waterbirds, or African-Eurasian Waterbird Agreement (AEWA), is an independent international treaty developed under the auspices of the United Nations Environment Programme's Convention on Migratory Species. Background The Agreement on the Conservation of African-Eurasian Migratory Waterbirds was drafted on 19 June 1995 in The Hague, Netherlands, in order to coordinate efforts to conserve bird species migrating between European and African nations. Description The AEWA is an independent treaty under the auspices of the Convention on Migratory Species, of the United Nations Environment Programme. The agreement focuses on bird species that depend on wetlands for at least part of their lifecycle and cross international borders in their migration patterns. As of 2023 it covered 255 species. As of July 2023, its scope covered territories in 119 Range States stretching from the Arctic to South Africa, encompassing the ...

Bird Conservation
Bird conservation is a field in the science of conservation biology related to threatened birds. Bird conservation efforts aim to protect species and mitigate the decline of threatened bird population numbers. According to Worldwatch Institute, many bird populations are currently declining worldwide, with 1,200 species facing extinction in the next century. Current estimates imply a total of nearly 11,000 extant species, suggesting that 11.6% of all bird species, a near ratio of one in nine birds, have gone extinct over the last 126,000 years of human history. The biggest cited reason surrounds habitat loss. Other threats include overhunting, accidental mortality due to structural collisions, long-line fishing bycatch, pollution, competition and predation by pet cats, oil spills and pesticide use and climate change. Governments, along with numerous conservation charities, work to protect birds in various ways, including legislation, preserving and restoring bird habitat, and ...

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 an inventory of the global conservation status and extinction risk of biological species. A series of Regional Red Lists, which assess the risk of extinction to species within a political management unit, are also produced by countries and organizations. The goals of the Red List are to provide scientifically based information on the status of species and subspecies at a global level, to draw attention to the magnitude and importance of threatened biodiversity, to influence national and international policy and decision-making, and to provide information to guide actions to conserve biological diversity. Major species assessors include BirdLife International, the Institute of Zoology (the research division of the Zoological Society of London), the World Conservation Monitoring Centre, and many Specialist Groups w ...

Least Concern
A least-concern species is a species that has been evaluated and categorized by the International Union for Conservation of Nature (IUCN) as not being a focus of wildlife 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 15,636) in the IUCN database still use the code "LR/lc", which indicates they have not been re- ...

Rice
Rice is a cereal grain and in its Domestication, domesticated form is the staple food of over half of the world's population, particularly in Asia and Africa. Rice is the seed of the grass species ''Oryza sativa'' (Asian rice)—or, much less commonly, ''Oryza glaberrima'' (African rice). Asian rice was domesticated in China some 13,500 to 8,200 years ago; African rice was domesticated in Africa about 3,000 years ago. Rice has become commonplace in many cultures worldwide; in 2023, 800 million tons were produced, placing it third after sugarcane and maize. Only some 8% of rice is traded internationally. China, India, and Indonesia are the largest consumers of rice. A substantial amount of the rice produced in developing nations is lost after harvest through factors such as poor transport and storage. Rice yields can be reduced by pests including insects, rodents, and birds, as well as by weeds, and by List of rice diseases, diseases such as rice blast. Traditional rice polyc ...

Forage
Forage is a plant material (mainly plant leaves and stems) eaten by grazing livestock. Historically, the term ''forage'' has meant only plants eaten by the animals directly as pasture, crop residue, or immature cereal crops, but it is also used more loosely to include similar plants cut for fodder and carried to the animals, especially as hay or silage. While the term ''forage'' has a broad definition, the term ''forage crop'' is used to define crops, annual or biennial, which are grown to be utilized by grazing or harvesting as a whole crop. Common forages Grasses Grass forages include: *''Agrostis'' spp. – bentgrasses **''Agrostis capillaris'' – common bentgrass **''Agrostis stolonifera'' – creeping bentgrass *''Andropogon hallii'' – sand bluestem *''Arrhenatherum elatius'' – false oat-grass *''Bothriochloa bladhii'' – Australian bluestem *''Bothriochloa pertusa'' – hurricane grass *''Brachiaria decumbens'' – Surinam grass *''Brachiaria humidicola'' – kor ...
