Saguinus Mystax
The moustached tamarin (''Saguinus mystax'') is a New World monkey and a species of tamarin. The moustached tamarin is named for the lack of coloring in the facial hair surrounding their mouth, appearing similar to a moustache. As with all New World monkeys, the moustached tamarin is found only in areas of Central and South America. Taxonomy There are 3 subspecies of the moustached tamarin: * Spix's moustached tamarin, ''Saguinus mystax mystax'' * White-rumped moustached tamarin, ''Saguinus mystax pluto'' * Red-capped tamarin, ''Saguinus mystax pileatus'' Description Moustached tamarins have a lifespan of about 20 years. They are small, weighing 500 to 600 grams, and range in length from 30 to 92 centimeters, with adult females larger than males. Moustached tamarin monkeys are characterized by white, curly hair around their mouth, similar to a moustache. Their face is flat with almond-like shaped eyes. Their ears are furry and large, and they have long, silky, body hair. T ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Johann Baptist Von Spix
Johann Baptist Ritter von Spix (9 February 1781 – 13 March 1826) was a German natural history, biologist. From his expedition to Brazil, he brought to Germany a large variety of specimens of plants, insects, mammals, birds, amphibians and fish. They constitute an important basis for today's National Zoological Collection in Munich. Numerous examples of his ethnographic collections, such as dance masks and the like, are now part of the collection of the Museum Five Continents, Museum of Ethnography in Munich. Biography Spix was born in Höchstadt, in present-day Middle Franconia, as the seventh of eleven children. His childhood home is the site of the Spix Museum, open to the public since 2004. He studied philosophy in Bamberg and graduated with a doctoral degree. Later he studied theology in Würzburg. After attending lectures of the young professor Friedrich Wilhelm Joseph Schelling, F. W. J. Schelling, Spix became interested in nature. He quit his theology studi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Frugivorous
A frugivore is an animal that thrives mostly on raw fruits or succulent fruit-like produce of plants such as roots, shoots, nuts and seeds. Approximately 20% of mammalian herbivores eat fruit. Frugivores are highly dependent on the abundance and nutritional composition of fruits. Frugivores can benefit or hinder fruit-producing plants by either dispersing or destroying their seeds through digestion. When both the fruit-producing plant and the frugivore benefit by fruit-eating behavior the interaction is a form of mutualism. Frugivore seed dispersal Seed dispersal is important for plants because it allows their progeny to move away from their parents over time. The advantages of seed dispersal may have led to the evolution of fleshy fruits, which entice animals to consume them and move the plant's seeds from place to place. While many fruit-producing plant species would not disperse far without frugivores, their seeds can usually germinate even if they fall to the ground directly ...

Tayras
The tayra (''Eira barbara'') is an omnivorous animal from the weasel family, native to the Americas. It is the only species in the genus ''Eira''. Tayras are also known as the ''tolomuco'' or ''perico ligero'' in Central America, ''motete'' in Honduras, ''irara'' in Brazil, ''san hol'' or ''viejo de monte'' in the Yucatan Peninsula, and high-woods dog (or historically ''chien bois'') in Trinidad. The genus name ''Eira'' is derived from the indigenous name of the animal in Bolivia and Peru, while ''barbara'' means "strange" or "foreign". Description Tayras are long, slender animals with an appearance similar to that of weasels and martens. They range from in length, not including a 37- to 46-cm-long (15 to 18 in) bushy tail, and weigh . Males are larger, and slightly more muscular, than females. They have short, dark brown to black fur which is relatively uniform across the body, limbs, and tail, except for a yellow or orange spot on the chest. The fur on the head and neck is ...

Quadrupedalism
Quadrupedalism is a form of locomotion where four limbs are used to bear weight and move around. An animal or machine that usually maintains a four-legged posture and moves using all four limbs is said to be a quadruped (from Latin ''quattuor'' for "four", and ''pes'', ''pedis'' for "foot"). Quadruped animals are found among both vertebrates and invertebrates. Quadrupeds vs. tetrapods Although the words ‘quadruped’ and ‘tetrapod’ are both derived from terms meaning ‘four-footed’, they have distinct meanings. A tetrapod is any member of the taxonomic unit Tetrapoda (which is defined by descent from a specific four-limbed ancestor), whereas a quadruped actually uses four limbs for locomotion. Not all tetrapods are quadrupeds and not all entities that could be described as ‘quadrupedal’ are tetrapods. This last meaning includes certain artificial objects; almost all quadruped ''organisms'' are tetrapods (with the exception of some raptorial arthropods adapted fo ...

Precocial
In biology, altricial species are those in which the young are underdeveloped at the time of birth, but with the aid of their parents mature after birth. Precocial species are those in which the young are relatively mature and mobile from the moment of birth or hatching. Precocial species are normally nidifugous, meaning that they leave the nest shortly after birth or hatching. These categories form a continuum, without distinct gaps between them. Altriciality Etymology The word is derived from the Latin root ''alere'', meaning "to nurse, to rear, or to nourish" and indicates the need for young to be fed and taken care of for a long duration. By contrast, species whose young are immediately or quickly mobile are called ''precocial''. Precociality Etymology The word "precocial" is derived from the same root as ''precocious'', implying early maturity in both cases. Superprecociality Extremely precocial species are called "superprecocial". Examples are the megapode birds, which ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Diurnality
Diurnality is a form of plant and ethology, animal behavior characterized by activity during daytime, with a period of sleeping or other inactivity at night. The common adjective used for daytime activity is "diurnal". The timing of activity by an animal depends on a variety of environmental factors such as the temperature, the ability to gather food by sight, the risk of predation, and the time of year. Diurnality is a cycle of activity within a 24-hour period; cyclic activities called circadian rhythms are endogenous cycles not dependent on external cues or environmental factors except for a zeitgeber. Animals active during twilight are crepuscular, those active during the night are nocturnal and animals active at sporadic times during both night and day are cathemerality, cathemeral. Plants that open their flowers during the daytime are described as diurnal, while those that bloom during nighttime are nocturnal. The timing of flower opening is often related to the time at which ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Arboreal
Arboreal locomotion is the Animal locomotion, locomotion of animals in trees. In habitats in which trees are present, animals have evolved to move in them. Some animals may scale trees only occasionally, but others are exclusively arboreal. The habitats pose numerous mechanical challenges to animals moving through them and lead to a variety of anatomical, behavioral and ecological consequences as well as variations throughout different species.Cartmill, M. (1985). Climbing. In ''Functional Vertebrate Morphology'', eds. M. Hildebrand D. M. Bramble K. F. Liem and D. B. Wake, pp. 73–88. Cambridge: Belknap Press. Furthermore, many of these same principles may be applied to climbing without trees, such as on rock piles or mountains. Some animals are exclusively arboreal in habitat, such as the tree snail. Biomechanics Arboreal habitats pose numerous mechanical challenges to animals moving in them, which have been solved in diverse ways. These challenges include moving on n ...

Geoffroy's Saddle-back Tamarin
Geoffroy's saddle-back tamarin (''Leontocebus nigrifrons'') is a species of saddle-back tamarin, a type of small monkey from South America. Geoffroy's saddle-back tamarin was formerly considered to be a subspecies of the brown-mantled tamarin, ''L. fuscicollis''. It lives in Loreto, Peru. Geoffroy's saddle-back tamarin has a head and body length of between and with a tail length between and long. Males weigh about and females weight about . It lives in groups with multiple males and females. It reaches sexual maturity at 18 months. Both males and females emigrate from their natal group. Geoffroy's saddle-back tamarin frequently associates with and forms mixed groups with moustached tamarins, ''Saguinus mystax''. The two species often sleep in the same tree and both species respond to each other's alarm calls. Its diet consists of fruits, gums, nectar, insects and other small animals. The IUCN rates it as least concern A least-concern species is a species tha ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Brown-mantled Tamarin
The brown-mantled tamarin (''Leontocebus fuscicollis''), also known as Spix's saddle-back tamarin, is a species of saddle-back tamarin. This New World monkey is found in the Southern American countries of Bolivia, Brazil and Peru.

Spatial Memory
In cognitive psychology and neuroscience, spatial memory is a form of memory responsible for the recording and recovery of information needed to plan a course to a location and to recall the location of an object or the occurrence of an event. Spatial memory is necessary for orientation in space. Spatial memory can also be divided into egocentric and allocentric spatial memory. A person's spatial memory is required to navigate around a familiar city. A rat's spatial memory is needed to learn the location of food at the end of a maze. In both humans and animals, spatial memories are summarized as a cognitive map. Spatial memory has representations within working, short-term memory and long-term memory. Research indicates that there are specific areas of the brain associated with spatial memory. Many methods are used for measuring spatial memory in children, adults, and animals. Short-term spatial memory Short-term memory (STM) can be described as a system allowing one to tempora ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
