Wolf-dog
A wolfdog is a canine produced by the mating of a domestic dog (''Canis familiaris'') with a gray wolf (''Canis lupus''), eastern wolf (''Canis lycaon''), red wolf (''Canis rufus''), or Ethiopian wolf (''Canis simensis'') to produce a hybrid. Admixture There are a range of experts who believe that they can tell the difference between a wolf, a dog, and a wolfdog, but they have been proven to be incorrect when providing their evidence before courts of law. Admixture between domestic dogs and other subspecies of gray wolves are the most common wolfdogs since dogs and gray wolves are considered the same species, are genetically very close and have shared vast portions of their ranges for millennia. Such admixture in the wild have been detected in many populations scattered throughout Europe and North America, usually occurring in areas where wolf populations have declined from human impacts and persecutions. At the same time, wolfdogs are also often bred in captivity for va ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Wolf
The wolf (''Canis lupus''; : wolves), also known as the grey wolf or gray wolf, is a Canis, canine native to Eurasia and North America. More than thirty subspecies of Canis lupus, subspecies of ''Canis lupus'' have been recognized, including the dog and dingo, though grey wolves, as popularly understood, only comprise Wild type, naturally-occurring wild subspecies. The wolf is the largest wild Neontology, extant member of the family Canidae, and is further distinguished from other ''Canis'' species by its less pointed ears and muzzle, as well as a shorter torso and a longer tail. The wolf is nonetheless related closely enough to smaller ''Canis'' species, such as the coyote and the golden jackal, to produce fertile Canid hybrid, hybrids with them. The wolf's fur is usually mottled white, brown, grey, and black, although subspecies in the arctic region may be nearly all white. Of all members of the genus ''Canis'', the wolf is most Generalist and specialist species, specializ ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Coywolf
A coywolf is a canid hybrid descended from coyotes (''Canis latrans''), Eastern wolf, eastern wolves (''Canis lycaon''), Gray wolf, gray wolves (''Canis lupus''), and dogs (''Canis familiaris''). All of these species are members of the genus ''Canis'' with 78 chromosomes; they therefore can interbreed. One genetic study indicates that these species genetic divergence, genetically diverged relatively recently (around 55,000–117,000 years ago). Genomic studies indicate that nearly all North American gray wolf populations possess some degree of admixture with coyotes following a geographic Cline (biology), cline, with the lowest levels occurring in Alaska, and the highest in Ontario and Quebec, as well as Atlantic Canada. Another term for these hybrids is sometimes wolfote. Description Hybrids of any combination tend to be larger than coyotes but smaller than wolves; they show behaviors intermediate between coyotes and the other parent's species. In one captive hybrid experiment, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ethiopian Wolf
The Ethiopian wolf (''Canis simensis''), also called the red jackal, the Simien jackal or Simien fox, is a canine native to the Ethiopian Highlands. In southeastern Ethiopia, it is also known as the horse jackal. It is similar to the coyote in size and build, and is distinguished by its long and narrow skull, and its red and white fur. Unlike most large canids, which are widespread, generalist feeders, the Ethiopian wolf is a highly specialised feeder of Afroalpine rodents with very specific habitat requirements. It is one of the world's rarest canids, and Africa's most endangered carnivore. The species's current range is limited to seven isolated mountain ranges at altitudes of 3,000–4,500 m, with the overall adult population estimated at 360–440 individuals in 2011, more than half of them in the Bale Mountains. The Ethiopian wolf is listed as endangered by the IUCN, on account of its small numbers and fragmented range. Threats include increasing pressure from expanding ...

Teotihuacan
Teotihuacan (; Spanish language, Spanish: ''Teotihuacán'', ; ) is an ancient Mesoamerican city located in a sub-valley of the Valley of Mexico, which is located in the State of Mexico, northeast of modern-day Mexico City. Teotihuacan is known today as the site of many of the most architecturally significant Mesoamerican pyramids built in the pre-Columbian Americas, namely the Pyramid of the Sun and the Pyramid of the Moon. Although close to Mexico City, Teotihuacan was not a Mexica (i.e. Aztec) city, and it predates the Aztec Empire by many centuries. At its zenith, perhaps in the first half of the first millennium (1 CE to 500 CE), Teotihuacan was the largest city in the Americas, with a population of at least 25,000, but has been estimated at 125,000 or more, making it at least the sixth-largest city in the world during its epoch. The city covered and 80 to 90 percent of the total population of the valley resided in Teotihuacan. Apart from the pyramids, Teotihu ...

Arctic Wolf
The Arctic wolf (''Canis lupus arctos''), also known as the white wolf, polar wolf, and the Arctic grey wolf, is a Subspecies of Canis lupus, subspecies of grey wolf native to the High Arctic tundra of Canada's Queen Elizabeth Islands, from Melville Island (Northwest Territories and Nunavut), Melville Island to Ellesmere Island. Unlike some populations that move between tundra and forest regions, Arctic wolves spend their entire lives north of the northern treeline. Their distribution to south is limited to the northern fringes of the Middle Arctic tundra on the southern half of Prince of Wales Island (Nunavut), Prince of Wales and Somerset Island (Nunavut), Somerset Islands. It is a medium-sized subspecies, distinguished from the northwestern wolf by its smaller size, whiter colouration, narrower Neurocranium, braincase,Goldman, E. A. (1964). Classification of wolves.

Coyote
The coyote (''Canis latrans''), also known as the American jackal, prairie wolf, or brush wolf, is a species of canis, canine native to North America. It is smaller than its close relative, the Wolf, gray wolf, and slightly smaller than the closely related eastern wolf and red wolf. It fills much of the same ecological niche as the golden jackal does in Eurasia; however, the coyote is generally larger. The coyote is listed as Least Concern, least concern by the International Union for Conservation of Nature, due to its wide distribution and abundance throughout North America. The species is versatile, able to adapt to and expand into environments modified by humans; urban coyotes are common in many cities. The coyote was sighted in eastern Panama (across the Panama Canal from their home range) for the first time in 2013. The coyote has 19 recognized subspecies. The average male weighs and the average female . Their fur color is predominantly light gray and red or fulvous int ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Eastern Wolf
The eastern wolf (''Canis lycaon'' or ''Canis lupus lycaon''), also known as the timber wolf, Algonquin wolf and eastern timber wolf, is a canine of debated taxonomy native to the Great Lakes region and southeastern Canada. It is considered either a unique subspecies of gray wolf, or red wolf, or a separate species from both. Many studies have found the eastern wolf to be the product of ancient and recent genetic admixture between the gray wolf and the coyote, while other studies have found some or all populations of the eastern wolf, as well as coyotes, originally separated from a common ancestor with the wolf over 1 million years ago and that these populations of the eastern wolf may be the same species as or a closely related species to the red wolf (''Canis lupus rufus'' or ''Canis rufus'') of the Southeastern United States. Regardless of its status, it is regarded as unique and therefore worthy of conservation with Canada citing the population in eastern Canada (also kn ...

Whole Genome Sequencing
Whole genome sequencing (WGS), also known as full genome sequencing or just genome sequencing, is the process of determining the entirety of the DNA sequence of an organism's genome at a single time. This entails sequencing all of an organism's chromosomal DNA as well as DNA contained in the mitochondrial DNA, mitochondria and, for plants, in the chloroplast. Whole genome sequencing has largely been used as a research tool, but was being introduced to clinics in 2014. In the future of personalized medicine, whole genome sequence data may be an important tool to guide therapeutic intervention. The tool of DNA sequencing, gene sequencing at Single-nucleotide polymorphism, SNP level is also used to pinpoint functional variants from association studies and improve the knowledge available to researchers interested in evolutionary biology, and hence may lay the foundation for predicting disease susceptibility and drug response. Whole genome sequencing should not be confused with DNA ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Apennines
The Apennines or Apennine Mountains ( ; or Ἀπέννινον ὄρος; or – a singular with plural meaning; )Latin ''Apenninus'' (Greek or ) has the form of an adjective, which would be segmented ''Apenn-inus'', often used with nouns such as ("mountain") or Greek (), but ''Apenninus'' is just as often used alone as a noun. The ancient Greeks and Romans typically but not always used "mountain" in the singular to mean one or a range; thus, "the Apennine mountain" refers to the entire chain and is translated "the Apennine mountains". The ending can vary also by gender depending on the noun modified. The Italian singular refers to one of the constituent chains rather than to a single mountain, and the Italian plural refers to multiple chains rather than to multiple mountains. are a mountain range consisting of parallel smaller chains extending the length of peninsular Italy. In the northwest they join the Ligurian Alps at Altare. In the southwest they end at Reggio di ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Protein
Proteins are large biomolecules and macromolecules that comprise one or more long chains of amino acid residue (biochemistry), residues. Proteins perform a vast array of functions within organisms, including Enzyme catalysis, catalysing metabolic reactions, DNA replication, Cell signaling, responding to stimuli, providing Cytoskeleton, structure to cells and Fibrous protein, organisms, and Intracellular transport, transporting molecules from one location to another. Proteins differ from one another primarily in their sequence of amino acids, which is dictated by the Nucleic acid sequence, nucleotide sequence of their genes, and which usually results in protein folding into a specific Protein structure, 3D structure that determines its activity. A linear chain of amino acid residues is called a polypeptide. A protein contains at least one long polypeptide. Short polypeptides, containing less than 20–30 residues, are rarely considered to be proteins and are commonly called pep ...
