Museonder
The Museonder is a Dutch museum in the Hoge Veluwe National Park, De Hoge Veluwe National Park The museum focuses on the geology and biology of the Veluwe and calls itself the world's first fully underground museum. The name "Museonder" is a portmanteau of the Dutch language, Dutch words for "museum" and "under", respectively "museum" and "onder". History The museum was opened in March 1993 by Prince Claus of the Netherlands. It was immediately praised for its modern approach to presenting information. Within six months it was reported that the number of visitors to the national park had risen by nearly half, largely due to the new museum. It was also made public that the museum suffered from vandalism and needed to hire more guards and to repair parts of the exhibition. In 2008, the directorate of the national park announced renovations to the park, including the Museonder. The museum would host changing exhibitions, in addition to the permanent presentation.

Hoge Veluwe National Park
De Hoge Veluwe National Park (, "The High Veluwe") is a Dutch national park in the province of Gelderland near the cities of Ede, Wageningen, Arnhem and Apeldoorn. It is approximately in area, consisting of heathlands, sand dunes, and woodlands. It is situated in the Veluwe, the area of the largest terminal moraine in the Netherlands. Most of the landscape of the park and the Veluwe was created during the last ice age. The alternating sand dune areas and heathlands may have been caused by human utilization of the surrounding lands. The park forms one of the largest continuous nature reserves in the Netherlands. History The park was established by the businessman Anton Kröller and his wife Helene Kröller-Müller as a private estate in 1909. Up until 1923 the park was under construction with wildlife being imported and the building of the hunting lodge and fences. The hunting residence is called ''St. Hubertus Hunting Lodge'' after St. Hubertus and was designed by prominent D ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Tree
In botany, a tree is a perennial plant with an elongated stem, or trunk, usually supporting branches and leaves. In some usages, the definition of a tree may be narrower, including only woody plants with secondary growth, plants that are usable as lumber or plants above a specified height. In wider definitions, the taller palms, tree ferns, bananas, and bamboos are also trees. Trees are not a taxonomic group but include a variety of plant species that have independently evolved a trunk and branches as a way to tower above other plants to compete for sunlight. The majority of tree species are angiosperms or hardwoods; of the rest, many are gymnosperms or softwoods. Trees tend to be long-lived, some reaching several thousand years old. Trees have been in existence for 370 million years. It is estimated that there are some three trillion mature trees in the world. A tree typically has many secondary branches supported clear of the ground by the trunk. This trunk typically ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Root
In vascular plants, the roots are the organs of a plant that are modified to provide anchorage for the plant and take in water and nutrients into the plant body, which allows plants to grow taller and faster. They are most often below the surface of the soil, but roots can also be aerial or aerating, that is, growing up above the ground or especially above water. Function The major functions of roots are absorption of water, plant nutrition and anchoring of the plant body to the ground. Anatomy Root morphology is divided into four zones: the root cap, the apical meristem, the elongation zone, and the hair. The root cap of new roots helps the root penetrate the soil. These root caps are sloughed off as the root goes deeper creating a slimy surface that provides lubrication. The apical meristem behind the root cap produces new root cells that elongate. Then, root hairs form that absorb water and mineral nutrients from the soil. The first root in seed producing plants is the r ...

Glacial Erratic
A glacial erratic is glacially deposited rock differing from the type of rock native to the area in which it rests. Erratics, which take their name from the Latin word ' ("to wander"), are carried by glacial ice, often over distances of hundreds of kilometres. Erratics can range in size from pebbles to large boulders such as Big Rock () in Alberta. Geologists identify erratics by studying the rocks surrounding the position of the erratic and the composition of the erratic itself. Erratics are significant because: *They can be transported by glaciers, and they are thereby one of a series of indicators which mark the path of prehistoric glacier movement. Their lithographic origin can be traced to the parent bedrock, allowing for confirmation of the ice flow route. *They can be transported by ice rafting. This allows quantification of the extent of glacial flooding resulting from ice dam failure which release the waters stored in proglacial lakes such as Lake Missoula. Erratics ...

Aurochs
The aurochs (''Bos primigenius'') ( or ) is an extinct cattle species, considered to be the wild ancestor of modern domestic cattle. With a shoulder height of up to in bulls and in cows, it was one of the largest herbivores in the Holocene; it had massive elongated and broad horns that reached in length. The aurochs was part of the Pleistocene megafauna. It probably evolved in Asia and migrated west and north during warm interglacial periods. The oldest known aurochs fossils found in India and North Africa date to the Middle Pleistocene and in Europe to the Holstein interglacial. As indicated by fossil remains in Northern Europe, it reached Denmark and southern Sweden during the Holocene. The aurochs declined during the late Holocene due to habitat loss and hunting, and became extinct when the last individual died in 1627 in Jaktorów forest in Poland. The aurochs is depicted in Paleolithic cave paintings, Neolithic petroglyphs, Ancient Egyptian reliefs and Bronze ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Straight-tusked Elephant
The straight-tusked elephant (''Palaeoloxodon antiquus'') is an extinct species of elephant that inhabited Europe and Western Asia during the Middle and Late Pleistocene (781,000–30,000 years before present). Recovered individuals have reached up to in height, and an estimated in weight. The straight-tusked elephant probably lived in small herds, flourishing in interglacial periods, when its range would extend as far north as Great Britain. Isolated tusks are often found while partial or whole skeletons are rare, and there is evidence of predation by early humans. It is the ancestral species of most dwarf elephants that inhabited islands in the Mediterranean. Description ''Palaeoloxodon antiquus'' was quite large, with individuals reaching in height. Like other members of '' Palaeoloxodon'', ''P. antiquus'' possesses a well developed parieto-occipital crest at the top of the cranium that anchored the splenius as well as possibly the rhomboid muscles to support the lar ...

Cave Bear
The cave bear (''Ursus spelaeus'') is a prehistoric species of bear that lived in Europe and Asia during the Pleistocene and became extinct about 24,000 years ago during the Last Glacial Maximum. Both the word "cave" and the scientific name ''spelaeus'' are used because fossils of this species were mostly found in caves. This reflects the views of experts that cave bears may have spent more time in caves than the brown bear, which uses caves only for hibernation. Taxonomy Cave bear skeletons were first described in 1774 by Johann Friedrich Esper, in his book ''Newly Discovered Zoolites of Unknown Four Footed Animals''. While scientists at the time considered that the skeletons could belong to apes, canids, felids, or even dragons or unicorns, Esper postulated that they actually belonged to polar bears. Twenty years later, Johann Christian Rosenmüller, an anatomist at Leipzig University, gave the species its binomial name. The bones were so numerous that most researcher ...

Woolly Rhinoceros
The woolly rhinoceros (''Coelodonta antiquitatis'') is an extinct species of rhinoceros that was common throughout Europe and Asia during the Pleistocene epoch and survived until the end of the last glacial period. The woolly rhinoceros was a member of the Pleistocene megafauna. The woolly rhinoceros was covered with long, thick hair that allowed it to survive in the extremely cold, harsh mammoth steppe. It had a massive hump reaching from its shoulder and fed mainly on herbaceous plants that grew in the steppe. Mummified carcasses preserved in permafrost and many bone remains of woolly rhinoceroses have been found. Images of woolly rhinoceroses are found among cave paintings in Europe and Asia. Taxonomy Woolly rhinoceros remains have been known long before the species was described, and were the basis for some mythical creatures. Native peoples of Siberia believed their horns were the claws of giant birds. A rhinoceros skull was found in Kl ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Extinction
Extinction is the termination of a kind of organism or of a group of kinds (taxon), usually a species. The moment of extinction is generally considered to be the death of the last individual of the species, although the capacity to breed and recover may have been lost before this point. Because a species' potential range may be very large, determining this moment is difficult, and is usually done retrospectively. This difficulty leads to phenomena such as Lazarus taxa, where a species presumed extinct abruptly "reappears" (typically in the fossil record) after a period of apparent absence. More than 99% of all species that ever lived on Earth, amounting to over five billion species, are estimated to have died out. It is estimated that there are currently around 8.7 million species of eukaryote globally, and possibly many times more if microorganisms, like bacteria, are included. Notable extinct animal species include non-avian dinosaurs, saber-toothed cats, dodos, m ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Skeleton
A skeleton is the structural frame that supports the body of an animal. There are several types of skeletons, including the exoskeleton, which is the stable outer shell of an organism, the endoskeleton, which forms the support structure inside the body, and the hydroskeleton, a flexible internal skeleton supported by fluid pressure. Vertebrates are animals with a vertebral column, and their skeletons are typically composed of bone and cartilage. Invertebrates are animals that lack a vertebral column. The skeletons of invertebrates vary, including hard exoskeleton shells, plated endoskeletons, or Sponge spicule, spicules. Cartilage is a rigid connective tissue that is found in the skeletal systems of vertebrates and invertebrates. Etymology The term ''skeleton'' comes . ''Sceleton'' is an archaic form of the word. Classification Skeletons can be defined by several attributes. Solid skeletons consist of hard substances, such as bone, cartilage, or cuticle. These can be further ...

Extant Taxon
Neontology is a part of biology that, in contrast to paleontology, deals with living (or, more generally, '' recent'') organisms. It is the study of extant taxa (singular: extant taxon): taxa (such as species, genera and families) with members still alive, as opposed to (all) being extinct. For example: * The moose (''Alces alces'') is an extant species, and the dodo (''Raphus cucullatus'') is an extinct species. * In the group of molluscs known as the cephalopods, there were approximately 600 extant species and 7,500 extinct species. A taxon can be classified as extinct if it is broadly agreed or certified that no members of the group are still alive. Conversely, an extinct taxon can be reclassified as extant if there are new discoveries of living species ("Lazarus species"), or if previously-known extant species are reclassified as members of the taxon. Most biologists, zoologists, and botanists are in practice neontologists, and the term neontologist is used large ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
