Pseudochirulus Mayeri
The pygmy ringtail possum (''Pseudochirulus mayeri'') is a species of marsupial in the family Pseudocheiridae. It is found in the montane forest regions of Papua New Guinea and West Papua, Indonesia.Hatfield, Lucy. "Pseudochirulus mayeri (pygmy ringtail)." ''Animal Diversity Web.'' Regents of the University of Michigan, 19 March 2011. Web. 14 October 2014http://animaldiversity.ummz.umich.edu/accounts/Pseudochirulus_mayeri//ref> They are "widespread along the Central Cordillera" and live at elevations between above sea level.” Pygmy ringtails are herbivores or “ arboreal folivores” that eat pollen, lichen, fungus and “epiphytic moss." ''P. mayeri'' also eat the bark of trees, which provides them with calcium and potassium. They have “large incisor” teeth which help with “clipping forage from plants” and have “selenodont molars” that help with “shredding ingested foliage." They have “an enlarged cecum that acts as a fermentation chamber” and allows ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Walter Rothschild, 2nd Baron Rothschild
Lionel Walter Rothschild, 2nd Baron Rothschild, Baron de Rothschild, (8 February 1868 – 27 August 1937) was a British banker, politician, zoologist and soldier, who was a member of the Rothschild family. As a Zionist leader, he was presented with the Balfour Declaration, which pledged British support for a Jewish national home in Palestine. Rothschild was the president of the Board of Deputies of British Jews from 1925 to 1926. Early life Walter Rothschild was born in London as the eldest son and heir of Emma Louise von Rothschild and Nathan Rothschild, 1st Baron Rothschild, an immensely wealthy financier of the international Rothschild financial dynasty and the first Jewish peer in England. The eldest of three children, Walter was deemed to have delicate health and was educated at home. As a young man, he travelled in Europe, attending the University of Bonn for a year before entering Magdalene College, Cambridge. In 1889, leaving Cambridge after two years, he was ...

Cecum
The cecum or caecum is a pouch within the peritoneum that is considered to be the beginning of the large intestine. It is typically located on the right side of the body (the same side of the body as the appendix (anatomy), appendix, to which it is joined). The word cecum (, plural ceca ) stems from the Latin ''wikt:caecus, caecus'' meaning blindness, blind. It receives chyme from the ileum, and connects to the ascending colon of the large intestine. It is separated from the ileum by the ileocecal valve (ICV) or Bauhin's valve. It is also separated from the Large intestine#Structure, colon by the cecocolic junction. While the cecum is usually intraperitoneal, the ascending colon is Retroperitoneal space, retroperitoneal. In herbivores, the cecum stores food material where bacteria are able to break down the cellulose. In humans, the cecum is involved in absorption of salts and electrolytes and lubricates the solid waste that passes into the large intestine. Structure Develo ...

Mammals Described In 1932
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 wi ...

Eastern Grass-owl
The eastern grass owl (''Tyto longimembris''), also known as Chinese grass owl or Australian grass owl, is a species of owl in the family Tytonidae. They feed predominantly on small rodents. Though some authorities consider this owl to be conspecific with the African grass owl, ''T. capensis'', other consider it to be a valid species. Description The eastern grass owl is a medium-sized owl, similar in size to the barn owl. Adult males measure from in length, while the larger females can measure from . The wingspan is from . The female weighs while the male weighs . They have dark brown or tan upper parts with pale spots. They have black and tan bars on its wings and a very pale beak, feathered legs, and dark brown eyes. Like all ''Tyto'' owls, it has a heart-shaped facial disk with brown buff and a white bordering. Call The eastern grass owl's primary call is like many other tyto owls.

Papuan Hawk-owl
The Papuan hawk-owl (''Uroglaux dimorpha'') is a medium-sized, sleek owl with a proportionately small head, long tail, and short, rounded wings. Its white facial disk is small and indistinct, with black streaks, and white eyebrows. It has buff-colored upperparts and barred black and brown underparts. Its eyes are bright yellow, and it has a gray to black bill. The male is larger than the female, which is unusual among owls. Though generally found in lowland rainforest or gallery forest in lowland savanna, the Papuan hawk-owl is occasionally found at elevations of up to above sea level. It is probably a resident species in its restricted range, New Guinea. Not much is known about the status of this species, as insufficient data exist to quantify its population. It is rarely seen, and may be threatened due to deforestation.

Greater Sooty Owl
The greater sooty owl (''Tyto tenebricosa'') is a medium to large owl found in south-eastern Australia, Montane rainforests of New Guinea and have been seen on Flinders Island in the Bass Strait. The lesser sooty owl (''T. multipunctata''), is sometimes considered to be conspecific with this species, in which case they are then together referred to as sooty owls. It is substantially smaller and occurs in the wet tropics region of North Queensland, Australia. Description Greater sooty owls have a finely white spotted head with scattered white spots on the wings. The females are lighter colored than the males. They appear to be the heaviest of the living species in the barn owl family, however the Tasmanian subspecies of the Australian masked owl is larger still. The females' length is and weighs . The smaller male has a length of and weighs . The wing length is 30–40 cm. The large dark eyes are set in a round large facial disk. The facial disk is dark gray-silver or ...

Pheromone
A pheromone () is a secreted or excreted chemical factor that triggers a social response in members of the same species. Pheromones are chemicals capable of acting like hormones outside the body of the secreting individual, to affect the behavior of the receiving individuals. There are ''alarm signal, alarm pheromones'', ''food trail pheromones'', ''sex pheromones'', and many others that affect behavior or physiology. Pheromones are used by many organisms, from basic unicellular prokaryotes to complex multicellular eukaryotes. Their use among insects has been particularly well documented. In addition, some vertebrates, plants and ciliates communicate by using pheromones. The ecological functions and evolution of pheromones are a major topic of research in the field of chemical ecology. Background The portmanteau word "pheromone" was coined by Peter Karlson and Martin Lüscher in 1959, based on the Greek φερω ''pheroo'' ('I carry') and ὁρμων ''hormon'' ('stimulating'). P ...

Olfaction
The sense of smell, or olfaction, is the special sense through which smells (or odors) are perceived. The sense of smell has many functions, including detecting desirable foods, hazards, and pheromones, and plays a role in taste. In humans, it occurs when an odor binds to a receptor within the nasal cavity, transmitting a signal through the olfactory system. Glomeruli aggregate signals from these receptors and transmit them to the olfactory bulb, where the sensory input will start to interact with parts of the brain responsible for smell identification, memory, and emotion. There are many different causes for alteration, lack, or disturbance to a normal sense of smell, and can include damage to the nose or smell receptors, or central problems affecting the brain. Some causes include upper respiratory infections, traumatic brain injury, and neurodegenerative disease. History of study Early scientific study of the sense of smell includes the extensive doctoral dissertation of ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
