Hoary Fox
The hoary fox or hoary zorro (''Lycalopex vetulus''), also known as ''raposinha-do-campo'' in Brazil ( Portuguese for "little fox of the meadow"), is a species of zorro or "false" fox endemic to Brazil. Unlike many other foxes, it feeds primarily on small invertebrates such as insects. Description The hoary fox has a short muzzle, small teeth, a short coat, and slender limbs. The upper part of the body is grey, and the underside of the body is cream or fawn. The tail is black on the tip with a marked dark stripe along the upper surface, which in male animals may extend all the way along the back to the nape of the neck. The ears and outside part of the legs are reddish or tawny, and the lower jaw is black. Some melanistic individuals have also been reported. It is small for a fox, weighing only , with a head and body length of , and a tail . Together with its slender form, the small size of the hoary fox makes it an agile and fast-running animal, while its relatively weak teeth ...

Blanford's Fox
Blanford's fox (''Vulpes cana'') is a small fox native to West Asia, Central Asia and parts of South Asia. It is listed as Least Concern on the IUCN Red List. Naming Blanford's fox is named after the English naturalist William Thomas Blanford, who described it in 1877. It is also known as the Afghan fox, royal fox, dog fox, hoary fox, steppe fox, black fox, king fox (), cliff fox or Balochistan fox. Description Blanford's fox is a small fox with wide ears and a long, bushy tail nearly equal to the length of its body. Its body size often varies geographically. In the Afghan-Iranian region, the collected specimens had head-body lengths of and tail lengths of , while specimens in Oman had a total length of and a tail length of . Weights of those specimens averaged , body lengths , tail . Among all extant canids, only the fennec fox is smaller than Blanford's. The body is brownish-grey, fading to light yellow on the belly. The winter coat is soft and woolly, with a dense bla ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Endemic Mammals Of Brazil
Endemism is the state of a species being found only 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 also be referred to as an ''endemism'' or, in scientific literature, as an ''endemite''. Similarly, many species found in the Western ghats of India are examples of endemism. Endemism is an important concept in conservation biology for measuring biodiversity in a particular place and evaluating the risk of extinction for species. Endemism is also of interest in evolutionary biology, because it provides clues about how changes in the environment cause species to undergo range shifts (potentially expanding their range into a larger area or becomin ...

South American Foxes
The South American foxes (''Lycalopex''), commonly called ''raposa'' in Portuguese language, Portuguese, or ''zorro'' in Spanish language, Spanish, are a genus inhabiting South America. Despite their name, they are not Vulpes, true foxes, but are a unique canid genus more closely related to wolves and jackals than to true foxes; some of them resemble foxes due to convergent evolution. The South American gray fox, ''Lycalopex griseus'', is the most common species, and is known for its large ears and a highly marketable, russet-fringed Fur, pelt. The second-oldest known fossils belonging to the genus were discovered in Chile, and date from 2.0 to 2.5 million years ago, in the mid- to late Pliocene. The Vorohué Formation of Argentina has provided older fossils, dating to the Uquian to Ensenadan (Late Pliocene). [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Weaning
Weaning is the process of gradually introducing an infant human or other mammal to what will be its adult diet while withdrawing the supply of its mother's milk. In the United Kingdom, UK, weaning primarily refers to the introduction of solid foods at 6 months; in the United States, US, it primarily refers to stopping breastfeeding. The process takes place only in mammals, as only mammals produce milk. The infant is considered to be fully weaned once it is no longer breastfeeding, fed by any breast milk (or bottled Infant formula, substitute). Humans In some cultures, weaning progresses with the introduction of feeding the child food that has been prechewed by the parent along with continued breastfeeding, a practice known as premastication. The practice was important throughout human history in that it naturally gave a child a greatly improved protein source in addition to preventing iron deficiency. However, premasticated food from caregivers of lower socioeconomic status i ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Sex Ratio
A sex ratio is the ratio of males to females in a population. As explained by Fisher's principle, for evolutionary reasons this is typically about 1:1 in species which reproduce sexually. However, many species deviate from an even sex ratio, either periodically or permanently. These include parthenogenic and androgenetic species, periodically mating organisms such as aphids, some eusocial wasps, bees, ants, and termites. Types In most species, the sex ratio varies according to the age profile of the population. It is generally divided into four subdivisions: * — ratio at fertilization * — ratio at birth * — ratio in sexually mature organisms ** The tertiary sex ratio is equivalent to the (ASR), which is defined as the ratio of adult males to females in a population. ** The operational sex ratio (OSR) is the ratio of ''sexually active'' males to females in a population, and is therefore derived from a subset of the individuals included when calculating the ASR. ...

Gestation
Gestation is the period of development during the carrying of an embryo, and later fetus, inside viviparous animals (the embryo develops within the parent). It is typical for mammals, but also occurs for some non-mammals. Mammals during pregnancy can have one or more gestations at the same time, for example in a multiple birth. The time interval of a gestation is called the '' gestation period''. In obstetrics, '' gestational age'' refers to the time since the onset of the last menses, which on average is fertilization age plus two weeks. Mammals In mammals, pregnancy begins when a zygote (fertilized ovum) implants in the female's uterus and ends once the fetus leaves the uterus during labor or an abortion (whether induced or spontaneous). Humans In humans, pregnancy can be defined clinically, biochemically or biologically. Clinically, pregnancy starts from first day of the mother's last period. Biochemically, pregnancy starts when a woman's human chorionic gonado ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
