Wied's Marmoset
Wied's marmoset (''Callithrix kuhlii''), also known as Wied's black-tufted-ear marmoset, is a New World monkey that lives in tropical and subtropical forests of eastern Brazil. Unlike other marmosets, Wied's marmoset lives in groups consisting of 4 or 5 females and 2 or 3 males (plus children). They are matriarchal, and only the dominant female is allowed to mate. Like other marmosets, the offspring are always born in pairs. Diet This monkey supplements its diet of sap with fruit, nectar, flowers and seeds, as well as spiders and insects. Since these are harvested from the middle and lower part of the forest, Wied's marmoset often travels and forages in the company of the golden-headed lion tamarin, which forages in the canopy. Natural Predators Wied's marmoset is eaten by birds of prey (the harpy eagle, the gray hawk, the roadside hawk and the white-tailed hawk), felines (the jaguar, jaguarundi and ocelot) and snakes. Behavior Wied's marmoset is highly social, spending much ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Ocelot
The ocelot (''Leopardus pardalis'') is a medium-sized spotted wild cat that reaches at the shoulders and weighs between on average. It was first described by Carl Linnaeus in 1758. Two subspecies are recognized. It is native to the southwestern United States, Mexico, Central and South America, and to the Caribbean islands of Trinidad and Margarita. It prefers areas close to water sources with dense vegetation cover and high prey availability. Typically active during twilight and at night, the ocelot tends to be solitary and territorial. It is efficient at climbing, leaping and swimming. It preys on small terrestrial mammals, such as armadillos, opossums, and lagomorphs. Both sexes become sexually mature at around two years of age and can breed throughout the year; peak mating season varies geographically. After a gestation period of two to three months the female gives birth to a litter of one to three kittens. They stay with their mother for up to two years, after which the ...

Endemic Fauna Of Brazil
Endemism is the state of a species being found in a single defined geographic location, such as an island, state, nation, country or other defined zone; organisms that are indigenous to a place are not endemic to it if they are also found elsewhere. For example, the Cape sugarbird is found exclusively in southwestern South Africa and is therefore said to be ''endemic'' to that particular part of the world. An endemic species can be also be referred to as an ''endemism'' or in scientific literature as an ''endemite''. For example '' Cytisus aeolicus'' is an endemite of the Italian flora. '' Adzharia renschi'' was once believed to be an endemite of the Caucasus, but it was later discovered to be a non-indigenous species from South America belonging to a different genus. The extreme opposite of an endemic species is one with a cosmopolitan distribution, having a global or widespread range. A rare alternative term for a species that is endemic is "precinctive", which applies to s ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Callithrix
''Callithrix'' is a genus of New World monkeys of the family Callitrichidae, the family containing marmosets and tamarins. The genus contains the Atlantic Forest marmosets. The name ''Callithrix'' is derived from the Greek words ''kallos'', meaning beautiful, and ''thrix'', meaning hair. Taxonomy The genera ''Mico'' and ''Callibella'' were formerly considered a subgenus of the genus ''Callithrix''. ''Callithrix'' differs from ''Mico'' in dental morphology and geographic distribution; ''Callithrix'' species are distributed near the Atlantic coast of Brazil, while ''Mico'' species are distributed further inland. ''Callithrix'' differs from ''Callibella'' in these features, as well as in size, with ''Callithrix'' species being significantly larger. ''Callithrix'' species differ from the tamarins of the genus ''Saguinus'' in that ''Callithrix'' has enlarged mandibular incisor teeth the same size as the canine teeth, which are used for gouging holes in trees to extract exudates. ...

Genotype
The genotype of an organism is its complete set of genetic material. Genotype can also be used to refer to the alleles or variants an individual carries in a particular gene or genetic location. The number of alleles an individual can have in a specific gene depends on the number of copies of each chromosome found in that species, also referred to as ploidy. In diploid species like humans, two full sets of chromosomes are present, meaning each individual has two alleles for any given gene. If both alleles are the same, the genotype is referred to as homozygous. If the alleles are different, the genotype is referred to as heterozygous. Genotype contributes to phenotype, the observable traits and characteristics in an individual or organism. The degree to which genotype affects phenotype depends on the trait. For example, the petal color in a pea plant is exclusively determined by genotype. The petals can be purple or white depending on the alleles present in the pea plant. Howev ...

Phenotype
In genetics, the phenotype () is the set of observable characteristics or traits of an organism. The term covers the organism's morphology or physical form and structure, its developmental processes, its biochemical and physiological properties, its behavior, and the products of behavior. An organism's phenotype results from two basic factors: the expression of an organism's genetic code, or its genotype, and the influence of environmental factors. Both factors may interact, further affecting phenotype. When two or more clearly different phenotypes exist in the same population of a species, the species is called polymorphic. A well-documented example of polymorphism is Labrador Retriever coloring; while the coat color depends on many genes, it is clearly seen in the environment as yellow, black, and brown. Richard Dawkins in 1978 and then again in his 1982 book ''The Extended Phenotype'' suggested that one can regard bird nests and other built structures such as cad ...

Uterus
The uterus (from Latin ''uterus'', plural ''uteri'') or womb () is the organ in the reproductive system of most female mammals, including humans that accommodates the embryonic and fetal development of one or more embryos until birth. The uterus is a hormone-responsive sex organ that contains glands in its lining that secrete uterine milk for embryonic nourishment. In the human, the lower end of the uterus, is a narrow part known as the isthmus that connects to the cervix, leading to the vagina. The upper end, the body of the uterus, is connected to the fallopian tubes, at the uterine horns, and the rounded part above the openings to the fallopian tubes is the fundus. The connection of the uterine cavity with a fallopian tube is called the uterotubal junction. The fertilized egg is carried to the uterus along the fallopian tube. It will have divided on its journey to form a blastocyst that will implant itself into the lining of the uterus – the endometrium, where it will ...

Zygote
A zygote (, ) is a eukaryotic cell formed by a fertilization event between two gametes. The zygote's genome is a combination of the DNA in each gamete, and contains all of the genetic information of a new individual organism. In multicellular organisms, the zygote is the earliest developmental stage. In humans and most other anisogamous organisms, a zygote is formed when an egg cell and sperm cell come together to create a new unique organism. In single-celled organisms, the zygote can divide asexually by mitosis to produce identical offspring. German zoologists Oscar and Richard Hertwig made some of the first discoveries on animal zygote formation in the late 19th century. Humans In human fertilization, a released ovum (a haploid secondary oocyte with replicate chromosome copies) and a haploid sperm cell (male gamete) combine to form a single diploid cell called the zygote. Once the single sperm fuses with the oocyte, the latter completes the division of the second ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
