Caspian Sea Wolf
The steppe wolf (''Canis lupus campestris''), also known as the Caspian Sea wolf, is a subspecies of grey wolf native to the Caspian steppes, the steppe regions of the Caucasus, the lower Volga region, southern Kazakhstan north to the middle of the Emba, and the steppe regions of the lower European part of the former Soviet Union. It may also occur in northern Afghanistan and Iran and occasionally the steppe regions of Romania and Hungary. The German name is ''der Steppenwolf'', whence the novel (1927) by German-Swiss author Hermann Hesse is named. Studies have shown that this type of wolf is known to carry rabies. Due to its close proximity to domestic animals, the need for a reliable vaccination is high. Rueness ''et al.'' (2014) showed that wolves in the Caucasus Mountains of the putative Caucasian subspecies, ''C. l. cubanensis'', are not genetically distinct enough to be considered a subspecies, but may represent a local ecomorph of ''C. l. lupus''.

Steppenwolf (novel)
''Steppenwolf'' (originally ) is the tenth novel by German-Swiss author Hermann Hesse. Originally published in Germany in 1927, it was first translated into English in 1929. The novel was named after the German name for the steppe wolf. The story in large part reflects a profound crisis in Hesse's spiritual world during the 1920s. ''Steppenwolf'' was wildly popular and has been a perpetual success across the decades, but Hesse later asserted that the book was largely misunderstood. Background and publication history In 1924, Hermann Hesse married singer Ruth Wenger. After several weeks, however, he left Basel, only returning near the end of the year. Upon his return, he rented a separate apartment, adding to his isolation. After a short trip to Germany with Wenger, Hesse stopped seeing her almost completely. The resulting feeling of isolation and inability to make lasting contact with the outside world led to increasing despair and the return of Hesse's suicidal thoughts. ...

Subspecies Of Canis Lupus
There are 38 subspecies of ''Canis lupus'' listed in the taxonomic authority ''Mammal Species of the World'' (2005, 3rd edition). These subspecies were named over the past 250 years, and since their naming, a number of them have gone extinct. The nominate subspecies is the Eurasian wolf (''Canis lupus lupus''). Taxonomy In 1758, the Swedish botanist and zoologist Carl Linnaeus published in his ''Systema Naturae'' the binomial nomenclature – or the two-word naming – of species. ''Canis'' is the Latin word meaning "dog", and under this genus he listed the dog-like carnivores including domestic dogs, wolves, and jackals. He classified the domestic dog as ''Canis familiaris'', and on the next page he classified the wolf as ''Canis lupus''. Linnaeus considered the dog to be a separate species from the wolf because of its head and body and tail ''cauda recurvata'' - its upturning tail - which is not found in any other canid. In 1999, a study of mitochondrial DNA indicated that th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Mammals Described In 1804
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 Sauropsida ...

Caspian Seal
The Caspian seal (''Pusa caspica'', syn. ''Phoca caspica'') is one of the smallest members of the earless seal family and unique in that it is found exclusively in the brackish Caspian Sea. It lives along the shorelines, but also on the many rocky islands and floating blocks of ice that dot the Caspian Sea. In winter and cooler parts of the spring and autumn season, it populates the northern Caspian coastline. As the ice melts in the summer and warmer parts of the spring and autumn season, it also occurs in the deltas of the Volga and Ural Rivers, as well as the southern latitudes of the Caspian where the water is cooler due to greater depth. Evidence suggests the seals are descended from Arctic ringed seals that reached the area from the north during an earlier part of the Quaternary period and became isolated in the landlocked Caspian Sea when continental ice sheets melted. Description Adults are about in length. Males are longer than females at an early age, but females exp ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Surplus Killing
Surplus killing, also known as excessive killing, killing for sport, henhouse syndrome, or overkill, is a common behavior exhibited by predators, in which they kill more prey than they can immediately eat and then they either cache or abandon the remainder. The term was invented by Dutch biologist Hans Kruuk after studying spotted hyenas in Africa and red foxes in England. Some of the other animals which have been observed engaging in surplus killing include orcas, zooplankton, humans, damselfly naiads, predaceous mites , martens, weasels, honey badgers, jaguar , leopards, lions, wolves, spiders, brown bears, American black bears, polar bears, coyotes, lynxes, minks, raccoons and dogs. Examples In Tasmania, in a single dog attack, 58 little penguins were killed. In mainland Australia, a single fox once killed around 74 penguins over several days, eating almost nothing. One leopard in Cape Province, South Africa killed 51 sheep and lambs in a single incident. Similarly, two cara ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Withers
The withers is the ridge between the shoulder blades of an animal, typically a quadruped. In many species, it is the tallest point of the body. In horses and dogs, it is the standard place to measure the animal's height. In contrast, cattle are often measured to the top of the hips. The term (pronounced ) derives from Old English ''wither'' (“against”), because it is the part of a draft animal that pushes against a load. Horses The withers in horses are formed by the dorsal spinal processes of roughly the 3rd through 11th thoracic vertebrae, which are unusually long in this area. Most horses have 18 thoracic vertebrae. The processes at the withers can be more than long. Since they do not move relative to the ground as the horse's head does, the withers are used as the measuring point for the height of a horse. Horses are sometimes measured in hands – one hand is . Horse heights are extremely variable, from small pony breeds to large draft breeds. The height at the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Eurasian Wolf
The Eurasian wolf (''Canis lupus lupus''), also known as the common wolf,Mech, L. David (1981), ''The Wolf: The Ecology and Behaviour of an Endangered Species'', University of Minnesota Press, p. 354, is a subspecies of grey wolf native to Europe and Asia. It was once widespread throughout Eurasia prior to the Middle Ages. Aside from an extensive paleontological record, Indo-European languages typically have several words for "wolf", thus attesting to the animal's abundance and cultural significance.Gamkrelidze, T. V. & Ivanov, V. V. (1995), ''Indo-European and the Indo-Europeans: A Reconstruction and Historical Analysis of a Proto-Language and Proto-Culture'', Walter de Gruyter, pp. 413-417, It was held in high regard in Baltic, Celtic, Slavic, Turkic, ancient Greek, Roman, and Thracian cultures, whilst having an ambivalent reputation in early Germanic cultures. It is the largest of Old World grey wolves, averaging in Europe; however, exceptionally large individuals have w ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Guard Dogs
A guard dog or watchdog (not to be confused with an attack dog) is a dog used to watch for and guard property against unwanted or unexpected human or animal intruders. The dog is discerning so that it does not annoy or attack the resident humans of the house. History The use of dogs as guardians is well known since ancient times. The Romans used to put mosaics (''Cave canem'' mosaics) at the entrance of the houses to warn visitors and intruders of the presence of dangerous dogs at the property. One of the first dog types used as guardians were the ancestral Mastiff-type landraces of the group known as Livestock guardian dogs which protected livestock against large predators such as wolves, bears and leopards. Orthrus is a famous example of a livestock guardian dog from the Greek mythology known for guarding Geryon's red cattle. Some ancient guard dogs in more urban areas, such as the extinct bandogges, were chained during the day and released at night to protect propert ...

Ecomorphology
Ecomorphology or ecological morphology is the study of the relationship between the ecological role of an individual and its morphological adaptations. The term "morphological" here is in the anatomical context. Both the morphology and ecology exhibited by an organism are directly or indirectly influenced by their environment, and ecomorphology aims to identify the differences. Current research places emphasis on linking morphology and ecological niche by measuring the performance of traits (i.e. sprint speed, bite force, etc.) associated behaviours, and fitness outcomes of the relationships. Current ecomorphological research focuses on a functional approach and application to the science. A broadening of this field welcomes further research in the debate regarding differences between both the ecological and morphological makeup of an organism. Development of ecomorphology The roots of ecomorphology date back to the late 19th century.Bock, W. J. 1994. Concepts and methods in ec ...

Hermann Hesse
Hermann Karl Hesse (; 2 July 1877 – 9 August 1962) was a German-Swiss poet, novelist, and painter. His best-known works include ''Demian'', ''Steppenwolf (novel), Steppenwolf'', ''Siddhartha (novel), Siddhartha'', and ''The Glass Bead Game'', each of which explores an individual's search for Authenticity (philosophy), authenticity, self-knowledge and spirituality. In 1946, he received the Nobel Prize in Literature. Life and work Family background Hermann Karl Hesse was born on 2 July 1877 in the Black Forest town of Calw in Kingdom of Württemberg, Württemberg, German Empire. His grandparents served in India at a mission under the auspices of the Basel Mission, a Protestant Christian missionary society. His grandfather Hermann Gundert compiled a Malayalam grammar and a Malayalam-English dictionary, and also contributed to a translation of the Bible into Malayalam in South India. Hesse's mother, Marie Gundert, was born at such a mission in South India in 1842. In descri ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
