Knettishall Heath
Knettishall Heath is a biological Site of Special Scientific Interest west of Knettishall in Suffolk. A larger area of 176 hectares is the Knettishall Heath Nature Reserve, which is managed by the Suffolk Wildlife Trust. Despite its name, Knettishall Heath is in fact a diverse mosaic of habitats with woodland and riverside meadows, as well as large areas of heath. Ecology The site is heath and grassland, mainly on acidic soils, with areas of secondary woodland and wet hollows. There are heathland plants such as sheep's sorrel, tormentil, harebell, ling and heath bedstraw, while wet areas have fen vegetation including water mint and yellow iris. Rare species Of the more than 12,500 species living in the Brecks, 30% are nationally rare. The heath is home to the rare grey carpet moth which is only found in Breckland, and the lunar yellow underwing moth. Seven bat species are found at Knettishall, including the nationally scarce barbastelle bat. Exmoor ponies In 2013, a five- ...

Site Of Special Scientific Interest
A Site of Special Scientific Interest (SSSI) in Great Britain or an Area of Special Scientific Interest (ASSI) in the Isle of Man and Northern Ireland is a conservation designation denoting a protected area in the United Kingdom and Isle of Man. SSSI/ASSIs are the basic building block of site-based nature conservation legislation and most other legal nature/geological conservation designations in the United Kingdom are based upon them, including national nature reserves, Ramsar sites, Special Protection Areas, and Special Areas of Conservation. The acronym "SSSI" is often pronounced "triple-S I". Selection and conservation Sites notified for their biological interest are known as Biological SSSIs (or ASSIs), and those notified for geological or physiographic interest are Geological SSSIs (or ASSIs). Sites may be divided into management units, with some areas including units that are noted for both biological and geological interest. Biological Biological SSSI/ASSIs may ...

Barbastelle Bat
The western barbastelle (''Barbastella barbastellus''), also known as the barbastelle or barbastelle bat, is a European bat in the genus ''Barbastella''. This species is found from Portugal to Azerbaijan and from Sweden to Canary Islands, where a sub-species was identified. It has a short nose, small eyes and wide ears. The conservation status of ''B. barbastellus'' is assessed as "near threatened", "vulnerable", "critically endangered" or "extinct" in various parts of its range. Taxonomy The western barbastelle was described as a new species in 1774 by Johann Christian Daniel von Schreber, who placed it in the genus ''Vespertilio'', with a species name of ''Vespertilio barbastellus''. The holotype had been collected in Burgundy, France. In 1836 it was placed in the genus ''Barbastellus'', and the first use of its current name combination of ''Barbastella barbastellus'' was in 1897 by Gerrit Smith Miller Jr. The name ''Barbastella barbastellus'' might be coming from the ...

Long Distance Trail
A long-distance trail (or long-distance footpath, track, way, greenway) is a longer recreational trail mainly through rural areas used for hiking, backpacking, cycling, horse riding or cross-country skiing. They exist on all continents except Antarctica. Many trails are marked on maps. Typically, a long-distance route will be at least long, but many run for several hundred miles, or longer. Many routes are waymarked and may cross public or private land and/or follow existing rights of way. Generally, the surface is not specially prepared, and the ground can be rough and uneven in areas, except in places such as converted rail tracks or popular walking routes where stone-pitching and slabs have been laid to prevent erosion. In some places, official trails will have the surface specially prepared to make the going easier. Historically Historically, and still nowadays in countries where most people move on foot or with pack animals, long-distance trails linked far away to ...

Chalk
Chalk is a soft, white, porous, sedimentary carbonate rock. It is a form of limestone composed of the mineral calcite and originally formed deep under the sea by the compression of microscopic plankton that had settled to the sea floor. Chalk is common throughout Western Europe, where deposits underlie parts of France, and steep cliffs are often seen where they meet the sea in places such as the Dover cliffs on the Kent coast of the English Channel. Chalk is mined for use in industry, such as for quicklime, bricks and builder's putty, and in agriculture, for raising pH in soils with high acidity. It is also used for " blackboard chalk" for writing and drawing on various types of surfaces, although these can also be manufactured from other carbonate-based minerals, or gypsum. Description Chalk is a fine-textured, earthy type of limestone distinguished by its light color, softness, and high porosity. It is composed mostly of tiny fragments of the calcite shells or skeletons ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ice Age
An ice age is a long period of reduction in the temperature of Earth's surface and atmosphere, resulting in the presence or expansion of continental and polar ice sheets and alpine glaciers. Earth's climate alternates between ice ages and greenhouse periods, during which there are no glaciers on the planet. Earth is currently in the Quaternary glaciation. Individual pulses of cold climate within an ice age are termed ''glacial periods'' (or, alternatively, ''glacials, glaciations, glacial stages, stadials, stades'', or colloquially, ''ice ages''), and intermittent warm periods within an ice age are called '' interglacials'' or ''interstadials''. In glaciology, ''ice age'' implies the presence of extensive ice sheets in both northern and southern hemispheres. By this definition, Earth is currently in an interglacial period—the Holocene. The amount of anthropogenic greenhouse gases emitted into Earth's oceans and atmosphere is predicted to prevent the next glacial period for th ...

Burial Mound
Burial, also known as interment or inhumation, is a method of final disposition whereby a dead body is placed into the ground, sometimes with objects. This is usually accomplished by excavating a pit or trench, placing the deceased and objects in it, and covering it over. A funeral is a ceremony that accompanies the final disposition. Humans have been burying their dead since shortly after the origin of the species. Burial is often seen as indicating respect for the dead. It has been used to prevent the odor of decay, to give family members closure and prevent them from witnessing the decomposition of their loved ones, and in many cultures it has been seen as a necessary step for the deceased to enter the afterlife or to give back to the cycle of life. Methods of burial may be heavily ritualized and can include natural burial (sometimes called "green burial"); embalming or mummification; and the use of containers for the dead, such as shrouds, coffins, grave liners, and bu ...

Bronze Age
The Bronze Age is a historic period, lasting approximately from 3300 BC to 1200 BC, characterized by the use of bronze, the presence of writing in some areas, and other early features of urban civilization. The Bronze Age is the second principal period of the three-age system proposed in 1836 by Christian Jürgensen Thomsen for classifying and studying ancient societies and history. An ancient civilization is deemed to be part of the Bronze Age because it either produced bronze by smelting its own copper and alloying it with tin, arsenic, or other metals, or traded other items for bronze from production areas elsewhere. Bronze is harder and more durable than the other metals available at the time, allowing Bronze Age civilizations to gain a technological advantage. While terrestrial iron is naturally abundant, the higher temperature required for smelting, , in addition to the greater difficulty of working with the metal, placed it out of reach of common use until the end o ...

Rabbit Warren
A warren is a network of wild rodent or lagomorph, typically rabbit burrows. Domestic warrens are artificial, enclosed establishment of animal husbandry dedicated to the raising of rabbits for meat and fur. The term evolved from the medieval Anglo-Norman concept of free warren, which had been, essentially, the equivalent of a hunting license for a given woodland. Architecture of the domestic warren The cunicularia of the monasteries may have more closely resembled hutches or pens, than the open enclosures with specialized structures which the domestic warren eventually became. Such an enclosure or ''close'' was called a ''cony-garth'', or sometimes ''conegar'', ''coneygree'' or "bury" (from "burrow"). Moat and pale To keep the rabbits from escaping, domestic warrens were usually provided with a fairly substantive moat, or ditch filled with water. Rabbits generally do not swim and avoid water. A ''pale'', or fence, was provided to exclude predators. Pillow mounds The most cha ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Rabbit Haemorrhagic Disease
Rabbit hemorrhagic disease (RHD), also known as viral hemorrhagic disease (VHD), is a highly infectious and lethal form of viral hepatitis that affects European rabbits. Some viral strains also affect hares and cottontail rabbits. Mortality rates generally range from 70 to 100 percent. The disease is caused by strains of ''rabbit hemorrhagic disease virus'' (RHDV), a lagovirus in the family ''Caliciviridae''. ''Rabbit hemorrhagic disease virus'' ''Rabbit hemorrhagic disease virus'' (RHDV) is a virus in the genus ''Lagovirus'' and the family ''Caliciviridae''. It is a nonenveloped virus with a diameter around 35–40 nm, icosahedral symmetry, and a linear positive-sense RNA genome of 6.4–8.5 kb. RHDV causes a generalized infection in rabbits that is characterized by liver necrosis, disseminated intravascular coagulation, and rapid death. Division into serotypes has been defined by a lack of cross-neutralization using specific antisera. Rabbit lagoviruses also include rel ...

Myxomatosis
Myxomatosis is a disease caused by ''Myxoma virus'', a poxvirus in the genus ''Leporipoxvirus''. The natural hosts are tapeti (''Sylvilagus brasiliensis'') in South and Central America, and brush rabbits (''Sylvilagus bachmani'') in North America. The myxoma virus causes only a mild disease in these species, but causes a severe and usually fatal disease in European rabbits (''Oryctolagus cuniculus''). Myxomatosis is an excellent example of what occurs when a virus jumps from a species adapted to it to a naive host, and has been extensively studied for this reason. The virus was intentionally introduced in Australia, France, and Chile in the 1950s to control wild European rabbit populations. Cause ''Myxoma virus'' is in the genus ''Leporipoxvirus'' (family ''Poxviridae''; subfamily ''Chordopoxvirinae''). Like other poxviruses, myxoma viruses are large DNA viruses with linear double-stranded DNA. Virus replication occurs in the cytoplasm of the cell. The natural hosts are tapet ...

Rabbits
Rabbits, also known as bunnies or bunny rabbits, are small mammals in the family Leporidae (which also contains the hares) of the order Lagomorpha (which also contains the pikas). ''Oryctolagus cuniculus'' includes the European rabbit species and its descendants, the world's 305 breeds of domestic rabbit. ''Sylvilagus'' includes 13 wild rabbit species, among them the seven types of cottontail. The European rabbit, which has been introduced on every continent except Antarctica, is familiar throughout the world as a wild prey animal and as a domesticated form of livestock and pet. With its widespread effect on ecologies and cultures, the rabbit is, in many areas of the world, a part of daily life—as food, clothing, a companion, and a source of artistic inspiration. Although once considered rodents, lagomorphs like rabbits have been discovered to have diverged separately and earlier than their rodent cousins and have a number of traits rodents lack, like two extra incisor ...

Exmoor Pony At Šlovický Vrch, Dobřany, 2019-02-23, 01
Exmoor is loosely defined as an area of hilly open moorland in west Somerset and north Devon in South West England. It is named after the River Exe, the source of which is situated in the centre of the area, two miles north-west of Simonsbath. Exmoor is more precisely defined as the area of the former ancient royal hunting forest, also called Exmoor, which was officially surveyed 1815–1818 as in extent. The moor has given its name to a National Park, which includes the Brendon Hills, the East Lyn Valley, the Vale of Porlock and of the Bristol Channel coast. The total area of the Exmoor National Park is , of which 71% is in Somerset and 29% in Devon. The upland area is underlain by sedimentary rocks dating from the Devonian and early Carboniferous periods with Triassic and Jurassic age rocks on lower slopes. Where these reach the coast, cliffs are formed which are cut with ravines and waterfalls. It was recognised as a heritage coast in 1991. The highest point on Exmoor is ...
