The jaguar (Panthera onca) is a large felid species and the only extant member of the genus Panthera native to the Americas. Hábitos, costumbres y taxonomía. Although reduced, its range remains large. The spots on the head and neck are generally solid, as are those on the tail, where they may merge to form a band. On average [6] [5], In 1758, Carl Linnaeus described the jaguar in his work Systema Naturae and gave it the scientific name Felis onca. Nevertheless, even in those times, the jaguar's chief prey was the capybara in South America, and the peccary further north. Los jaguares son los mayores felinos del continente americano. Male ranges cover roughly twice as much area, varying in size with the availability of game and space, and do not overlap. [102] The name of zipa Nemequene was derived from the Muysccubun words nymy and quyne, meaning "force of the jaguar". El jaguar tiene un cuerpo compacto, cabeza ancha y una mandíbula poderosa. Results of jaguar mitochondrial DNA analysis indicate that the species' lineage evolved between 280,000 and 510,000 years ago. If you know someone who is destroying the habitat, hurting or hunting the [8] Pocock did not have access to sufficient zoological specimens to critically evaluate their subspecific status, but expressed doubt about the status of several. The jaguar enjoys swimming, and is largely a solitary, opportunistic, stalk-and-ambush predator at the top of the food chain. It is listed as Near Threatened on the IUCN Red List; a… [89], To estimate population sizes within specific areas and to keep track of individual jaguars, camera trapping and wildlife tracking telemetry are widely used, and feces may be sought out with the help of detector dogs to study jaguar health and diet. The Aztec civilization shared this image of the jaguar as the representative of the ruler and as a warrior. [57], The activity patterns of the jaguar have been found to coincide with the activity of their main prey species in their biomes. It is the national animal of Guyana, and is featured in its Coat of arms of Guyana. Baker, Natural History and Behavior, pp. A year earlier, 125–180 jaguars were estimated to be living in Mexico's 4,000-km2 (2400-mi2) Calakmul Biosphere Reserve, with another 350 in the state of Chiapas. [7] In 1939, Reginald Innes Pocock recognized eight subspecies based on geographic origins and skull morphology of these specimens. Where present, it also preys on Odocoileus deer, spectacled caiman (Caiman crocodilus), South American tapir (Tapirus terrestris), crab-eating fox (Cerdocyon thous), tapeti (Sylvilagus brasiliensis) and agouti species. [28] It has lost habitat most rapidly in drier regions such as the Argentine pampas, the arid grasslands of Mexico and the southwestern United States. Pairs separate after mating, and females provide all parenting. [80] Detailed work performed under the auspices of the Wildlife Conservation Society revealed the species has lost 37% of its historic range, with its status unknown in an additional 18% of the global range. ... los jaguares tienen unas características físicas que los distinguen de sus primos del género Panthera. binocular vision and retractable nails on its legs, jaguars are used to [9] By 2005, nine subspecies were considered to be valid taxa. Conservation organizations may thus focus on providing viable, connected habitat for the jaguar, with the knowledge other species will also benefit. It kills capybara by piercing its canine teeth through the temporal bones of the capybara's skull, breaking its zygomatic arch and mandible and penetrating its brain, often through the ears. In 1999, its historic range at the turn of the 20th century was estimated at 19,000,000 km2 (7,300,000 sq mi) stretching from the southern United States through Central America to southern Argentina. Given its historical distribution, the jaguar has featured prominently in the mythology of numerous indigenous peoples of the Americas, including those of the Maya and Aztec civilizations. This spotted cat closely resembles the leopard, but is usually larger and sturdier. [51], Like all cats, the jaguar is an obligate carnivore, feeding only on meat. Adults generally meet only to court and mate (though limited noncourting socialization has been observed anecdotally[60]) and carve out large territories for themselves. The description of P. o. palustris was based on a fossil skull. Baker, Hand-rearing, pp. The countries included in this range are Argentina, Belize, Bolivia, Colombia, Costa Rica (particularly on the Osa Peninsula), Ecuador, French Guiana, Guatemala, Guyana, Honduras, Nicaragua, Panama, Paraguay, Peru, Suriname, the United States and Venezuela. He therefore concluded that they are most closely related to each other. This willingness to take livestock has induced ranch owners to hire full-time jaguar hunters.[69]. [54], Its bite force allows it to pierce the shells of armored reptiles and turtles. [1] Trophy hunting is still permitted in Bolivia, and it is not protected in Ecuador or Guyana. [21][22][23][24], Its immediate ancestor was Panthera onca augusta, which was larger than the contemporary jaguar. [46], In pre-Columbian Central and South America, the jaguar was a symbol of power and strength. Hunting jaguars is prohibited in Argentina, Brazil, Colombia, French Guiana, Honduras, Nicaragua, Panama, Paraguay, Suriname, the United States, and Venezuela. El jaguar es el tercer felino más grande en el mundo, detrás de los leones y tigres. separate and live solitary all their lives, only other Jaguars frequent in [110] In the spirit of the ancient Mayan culture, the 1968 Summer Olympics in Mexico City adopted a red jaguar as the first official Olympic mascot. [81], The major risks to the jaguar include deforestation across its habitat, increasing competition for food with human beings, especially in dry and unproductive habitat,[1][82] poaching, hurricanes in northern parts of its range, and the behavior of ranchers who will often kill the cat where it preys on livestock. ", "Planning to save a species: the jaguar as a model", "Jaguar spotting: A new wild cat may be roaming the United States", "Conservation units, priority areas and dispersal corridors for jaguars in Brazil", "Occupancy estimation of jaguar Panthera onca to assess the value of east-central Mexico as a jaguar corridor", "Structure and Character: Keystone Species", "Are large predators keystone species in Neotropical forests? Both sexes hunt, but males travel farther each day than females, befitting their larger territories. Vídeo. Specific areas of high importance for jaguar conservation, so-called "Jaguar Conservation Units" (JCU) were determined in 2000. Current conservation efforts often focus on educating ranch owners and promoting ecotourism. After killing prey, the jaguar will drag the carcass to a thicket or other secluded spot. [3] The jaguar is the largest native cat species of the New World, and the third largest in the world. In the 19th and 20th centuries, several jaguar type specimens formed the basis for descriptions of subspecies. Each unit was assessed and evaluated on the basis of size, connectivity, habitat quality for both jaguar and prey, and jaguar population status. In northern Mexico, the jaguar and cougar were found to almost always live in the same areas with neither species having areas where it was the only one of the two living. Jaguar fossils were discovered in Whitman County, Washington, Fossil Lake (Oregon), Niobrara, Nebraska, Franklin County, Tennessee, Edwards County, Texas, and in eastern Florida. The spots and their shapes vary between individual jaguars: rosettes may include one or several dots. serious danger of extinction. [101] The skins were traded with the lowland peoples of the tropical Orinoquía Region. During this period, the biggest exporters were Brazil and Paraguay, and the biggest importers were the US and Germany. mating season, their gestation lasts between 90 and 110 days. [107] The flag of the Department of Amazonas features a black jaguar silhouette pouncing towards a hunter. The international trade of jaguar skins had its largest boom between the end of the Second World War and the early 1970, due to the growing economy and lack of regulations. [37], Melanistic jaguars are informally known as black panthers. Researchers typically focus on particular bioregions, thus species-wide analysis is scant. [51], In South America, however, where the jaguar are larger than the cougar, the jaguar tends to take larger prey, usually over 22 kg (49 lb) and the cougar smaller prey, usually between 2 and 22 kg (4 and 49 lb), which reduces the cougar's average size. The jaguar stands 63 to 76 cm (25 to 30 in) tall at the shoulders. [19], Since 2017, the jaguar is therefore considered to be a monotypic taxon. [60][105] Remains of jaguar bones were discovered in a burial site in Guatemala which indicates that Mayans kept jaguars as pets. They have a keen sense of sight as well as hearing and smell, they are very [1], The jaguar prefers dense forest and typically inhabits dry deciduous forests, tropical and subtropical moist broadleaf forests, rainforests and cloud forests in Central and South America; open, seasonally flooded wetlands, dry grassland and historically also oak forests in the United States. The gorget shows evenly-engraved lines and measures 104 mm × 98 mm (4.1 in × 3.9 in). In the Andes, a jaguar cult disseminated by the early Chavín culture became accepted over most of today's Peru by 900 BC. When adapted to the prey, the jaguar has been shown to take cattle as a large portion of its diet; while land clearance for grazing is a problem for the species, the jaguar population may have increased when cattle were first introduced to South America, as the animals took advantage of the new prey base. [22][23][24], The jaguar is thought to have genetically diverged from a common ancestor of the Panthera at least 1.5 million years ago and to have entered the American continent in the Early Pleistocene via Beringia, the land bridge that once spanned the Bering Strait. Características del jaguar. Human attitudes in the areas surrounding reserves and laws and regulations to prevent poaching are essential to make conservation areas effective. The length, from the nose to the base of the tail, varies from 1.12 to 1.85 m (3 ft 8 in to 6 ft 1 in). as deer and tapirs. [76] However, such behavior appears to be more frequent where humans enter jaguar habitat, and decrease prey. In Aztec mythology, the jaguar was considered to be the totem animal of the powerful deity Tezcatlipoca. Hay muchas características resaltantes de este animal, tales como su implacable mordida (la más fuerte de todos los félidos), o su estructura musculo-esquelética que le da un aspecto muy feroz y ventaja demasiado amplia para con sus presas.
