Description

The jaguar is a compact and muscular animal. It is the largest cat native to the Americas and the third largest in the world, exceeded in size only by the tiger and the lion.

Exceptionally big males have been recorded to weigh as much as . The smallest females from Middle America weigh about . It is

ranges from pale yellow to tan or reddish-yellow, with a whitish underside and covered in black spots. The spots and their shapes vary: on the sides, they become rosettes which may include one or several dots. The spots on the head and neck are generally solid, as are those on the tail where they may merge to form bands near the end and create a black tip. They are elongated on the middle of the back, often connecting to create a median stripe, and blotchy on the belly. These patterns serve as

Jaguars living in forests are often darker and considerably smaller than those living in open areas, possibly due to the smaller numbers of large, herbivorous prey in forest areas.

Jaguars are also good at climbing trees but do so less often than cougars.

This situation may be advantageous to the cougar. Its broader prey niche, including its ability to take smaller prey, may give it an advantage over the jaguar in human-altered landscapes.

and penetrating its brain, often through the ears. It has been hypothesized to be an adaptation to cracking open turtle shells; armored reptiles may have formed an abundant prey base for the jaguar following the late Pleistocene extinctions. However, this is disputed, as even in areas where jaguars prey on reptiles, they are still taken relatively infrequently compared to mammals in spite of their greater abundance. Between October 2001 and April 2004, 10 jaguars were monitored in the southern Pantanal. In the dry season from April to September, they killed prey at intervals ranging from one to seven days; and ranging from one to 16 days in the wet season from October to March. The jaguar uses a stalk-and-ambush strategy when hunting rather than chasing prey. The cat will slowly walk down forest paths, listening for and stalking prey before rushing or ambushing. The jaguar attacks from cover and usually from a target's blind spot with a quick pounce; the species' ambushing abilities are considered nearly peerless in the animal kingdom by both indigenous people and field researchers and are probably a product of its role as an apex predator in several different environments. The ambush may include leaping into water after prey, as a jaguar is quite capable of carrying a large kill while swimming; its strength is such that carcasses as large as a Heifer (cow), heifer can be hauled up a tree to avoid flood levels. After killing prey, the jaguar will drag the carcass to a thicket or other secluded spot. It begins eating at the neck and chest. The heart and lungs are consumed, followed by the shoulders.


Social activity

The jaguar is generally Solitary animal, solitary except for females with cubs. In 1977, groups consisting of a male, female and cubs, and two females with two males were sighted several times in a study area in the Paraguay River valley; a radio-collared female moved in a home range of , which partly overlapped with another female. The home range of the male in this study area overlapped with several females. In the Venezuelan Llanos and Brazilian
Pantanal The Pantanal () is a natural region encompassing the world's largest tropical wetland area, and the world's largest Flooded grasslands and savannas, flooded grasslands. It is located mostly within the Brazilian state of Mato Grosso do Sul, but i ...
, male coalitions were detected, which marked, defended and invaded territories together, hunted together and mated with several females. The jaguar uses scrape marks, urine, and feces to Territorial marking, mark its territory. The size of home ranges depends on the level of deforestation and human population density. The home ranges of females vary from in the Pantanal to in the Amazon to in the Atlantic Forest. Male jaguar home ranges vary from in the Pantanal to in the Amazon to in the Atlantic Forest and in the Cerrado. Studies employing Global Positioning System, GPS telemetry in 2003 and 2004 found densities of only six to seven jaguars per in the Pantanal region, compared with 10 to 11 using traditional methods; this suggests the widely used sampling methods may inflate the actual numbers of individuals in a sampling area. Fights between males occur but are rare, and avoidance behavior has been observed in the wild. In one wetland population with degraded territorial boundaries and more social proximity, adults of the same sex are more tolerant of each other and engage in more friendly and co-operative interactions. The jaguar roars/grunts for long-distance communication; intensive bouts of counter-calling between individuals have been observed in the wild. This vocalization is described as "hoarse" with five or six guttural notes. prusten, Chuffing is produced by individuals when greeting, during Courtship display, courting, or by a mother comforting her cubs. This sound is described as low intensity snorts, possibly intended to signal tranquility and passivity. Cubs have been recorded bleating, gurgling and mewing.


Reproduction and life cycle

In captivity, the female jaguar is recorded to reach sexual maturity at the age of about 2.5 years. Estrus lasts 7–15 days with an estrus cycle of 41.8 to 52.6 days. During estrus, she exhibits increased restlessness with rolling and prolonged vocalizations. She is an induced ovulator but can also ovulate spontaneously. Gestation lasts 91 to 111 days. The male is sexually mature at the age of three to four years. His mean ejaculate volume is 8.6±1.3 ml. Generation time, Generation length of the jaguar is 9.8 years. In the Pantanal, breeding pairs were observed to stay together for up to five days. Females had one to two cubs. The young are born with closed eyes but open them after two weeks. Cubs are weaned at the age of three months but remain in the birth den for six months before leaving to accompany their mother on hunts. Jaguars remain with their mothers for up to two years. They appear to rarely live beyond 11 years, but captive individuals may live 22 years. In 2001, a male jaguar killed and partially consumed two cubs in Emas National Park. DNA paternity testing of blood samples revealed that the male was the father of the cubs. Two more cases of Infanticide (zoology), infanticide were documented in the northern Pantanal in 2013. To defend against infanticide, the female may hide her cubs and distract the male with courtship behavior.


Attacks on humans

The Spanish conquistadors feared the jaguar. According to Charles Darwin, the indigenous peoples of South America stated that people did not need to fear the jaguar as long as capybaras were abundant. The first official record of a jaguar killing a human in Brazil dates to June 2008. Two children were attacked by jaguars in Guyana. The majority of known attacks on people happened when it had been cornered or wounded.


Threats

The jaguar is threatened by habitat loss, loss and habitat fragmentation, fragmentation of habitat, illegal killing in retaliation for livestock depredation and for illegal trade in jaguar body parts. It is listed as
Near Threatened A near-threatened species is a species which has been Conservation status, categorized as "Near Threatened" (NT) by the International Union for Conservation of Nature (IUCN) as that may be vulnerable to Endangered species, endangerment in the ne ...

since 2002, as the jaguar population has probably declined by 20–25% since the mid-1990s. Deforestation is a major threat to the jaguar across its range. Habitat loss was most rapid in drier regions such as the Argentine pampas, the arid grasslands of Mexico and the southwestern United States. In 2002, it was estimated that the range of the jaguar had declined to about 46% of its range in the early 20th century. In 2018, it was estimated that its range had declined by 55% in the last century. The only remaining stronghold is the Amazon rainforest, a region that is rapidly being fragmented by deforestation. Between 2000 and 2012, forest loss in the jaguar range amounted to , with fragmentation increasing in particular in corridors between Jaguar Conservation Units (JCUs). By 2014, direct linkages between two JCUs in Bolivia were lost, and two JCUs in northern Argentina became completely isolated due to deforestation. In Mexico, the jaguar is primarily threatened by

. Its habitat is fragmented in northern Mexico, in the Gulf of Mexico and the Yucatán Peninsula, caused by changes in land use, construction of roads and tourism infrastructure. In Panama, 220 of 230 jaguars were killed in retaliation for predation on livestock between 1998 and 2014. In Venezuela, the jaguar was extirpated in about 26% of its range in the country since 1940, mostly in dry savannas and unproductive scrubland in the northeastern region of Anzoátegui. In Ecuador, the jaguar is threatened by reduced prey availability in areas where the expansion of the road network facilitated access of human hunters to forests. In the Alto Paraná Atlantic forests, at least 117 jaguars were killed in Iguaçu National Park and the adjacent Misiones Province between 1995 and 2008. Some Afro-Colombians in the Colombian Chocó Department hunt jaguars for consumption and sale of meat. Between 2008 and 2012, at least 15 jaguars were killed by livestock farmers in central Belize. The international trade of jaguar skins boomed between the end of the Second World War and the early 1970s. Significant declines occurred in the 1960s, as more than 15,000 jaguars were yearly killed for their skins in the Brazilian Amazon alone; the trade in jaguar skins decreased since 1973 when the CITES, Convention on International Trade in Endangered Species was enacted. Interview surveys with 533 people in the northwestern Bolivian Amazon revealed that local people killed jaguars out of fear, in retaliation, and for trade. Between August 2016 and August 2019, jaguar skins and body parts were seen for sale in tourist markets in the Peruvian cities of Lima, Iquitos and Pucallpa. Human-wildlife conflict, opportunistic hunting and hunting for trade in domestic markets are key drivers for killing jaguars in Belize and Guatemala. Seizure reports indicate that at least 857 jaguars were involved in trade between 2012 and 2018, including 482 individuals in Bolivia alone; 31 jaguars were seized in China. Between 2014 and early 2019, 760 jaguar fangs were seized that originated in Bolivia and were destined for China. Undercover investigations revealed that the smuggling of jaguar body parts is run by Chinese residents in Bolivia.


Conservation

The jaguar is listed on CITES Appendix I, which means that all international commercial trade in jaguars or their body parts is prohibited. Hunting jaguars is prohibited in Argentina, Brazil, Colombia, French Guiana, Honduras, Nicaragua, Panama, Paraguay, Suriname, the United States, and Venezuela. Hunting jaguars is restricted in Guatemala and Peru. In Ecuador, hunting jaguars is prohibited, and it is classified as threatened with extinction. In Guyana, it is protected as an endangered species, and hunting it is illegal. In 1986, the Cockscomb Basin Wildlife Sanctuary was established in Belize as the world's first protected area for jaguar conservation.


Jaguar Conservation Units

In 1999, field scientists from 18 jaguar range countries determined the most important areas for long-term jaguar conservation based on the status of jaguar population units, stability of prey base and quality of habitat. These areas, called "Jaguar Conservation Units" (JCUs), are large enough for at least 50 breeding individuals and range in size from ; 51 JCUs were designated in 36 geographic regions including: * the
Sierra Madre Occidental The Sierra Madre Occidental is a major mountain range system of the North American Cordillera, that runs northwest–southeast through northwestern and western Mexico, and along the Gulf of California. The Sierra Madre is part of the American C ...
and Sierra de Tamaulipas in Mexico * the Selva Maya tropical forests extending over Mexico, Belize and Guatemala * the Chocó–Darién moist forests from Honduras and Panama to Colombia * Venezuelan Llanos * northern Cerrado and Amazon basin in Brazil * Tropical Andes in Bolivia and Peru * Misiones Province in Argentina Optimal routes of travel between core jaguar population units were identified across its range in 2010 to implement wildlife corridors that connect JCUs. These corridors represent areas with the shortest distance between jaguar breeding populations, require the least possible energy input of dispersal (ecology), dispersing individuals and pose a low mortality risk. They cover an area of and range in length from in Mexico and Central America and from in South America. Cooperation with local landowners and municipal, state, or federal agencies is essential to maintain connected populations and prevent fragmentation in both JCUs and corridors. Seven of 13 corridors in Mexico are functioning with a width of at least and a length of no more than . The other corridors may hamper passage, as they are narrower and longer. In August 2012, the United States Fish and Wildlife Service set aside in Arizona and New Mexico for the protection of the jaguar. The Jaguar Recovery Plan was published in April 2019, in which Interstate 10 is considered to form the northern boundary of the Jaguar Recovery Unit in Arizona and New Mexico. In Mexico, a national conservation strategy was developed from 2005 on and published in 2016. The Mexican jaguar population increased from an estimated 4,000 individuals in 2010 to about 4,800 individuals in 2018. This increase is seen as a positive effect of conservation measures that were implemented in cooperation with governmental and non-governmental institutions and landowners. An evaluation of JCUs from Mexico to Argentina revealed that they overlap with high-quality habitats of about 1,500 mammals to varying degrees. Since co-occurring mammals benefit from the JCU approach, the jaguar has been called an umbrella species. Central American JCUs overlap with the habitat of 187 of 304 regional endemic amphibian and reptile species, of which 19 amphibians occur only in the jaguar range.


Approaches

In setting up protected reserves, efforts generally also have to be focused on the surrounding areas, as jaguars are unlikely to confine themselves to the bounds of a reservation, especially if the population is increasing in size. Human attitudes in the areas surrounding reserves and laws and regulations to prevent poaching are essential to make conservation areas effective. To estimate population sizes within specific areas and to keep track of individual jaguars, camera trapping and Telemetry#Fishery and wildlife research and management, wildlife tracking telemetry are widely used, and feces are sought out with the help of detection dogs to study jaguar health and diet. Current conservation efforts often focus on educating ranch owners and promoting ecotourism. Ecotourism setups are being used to generate public interest in charismatic animals such as the jaguar while at the same time generating revenue that can be used in conservation efforts. A key concern in jaguar ecotourism is the considerable habitat space the species requires. If ecotourism is used to aid in jaguar conservation, some considerations need to be made as to how existing ecosystems will be kept intact, or how new ecosystems will be put into place that are large enough to support a growing jaguar population. Conservationists and professionals in Mexico and the United States have established the Northern Jaguar Reserve in northern Mexico. Advocacy for reintroduction of the jaguar to its former range in Arizona and New Mexico have been supported by documentation of natural migrations by individual jaguars into the southern reaches of both states, the recency of extirpation from those regions by human action, and supportive arguments pertaining to biodiversity, ecological, human, and practical considerations.


In culture and mythology

In the pre-Columbian era, pre-Columbian Americas, the jaguar was a symbol of power and strength. In the Andes, a jaguar cult disseminated by the early Chavín culture became accepted over most of today's Peru by 900 Before Christ, BC. The later Moche (culture), Moche culture in northern Peru used the jaguar as a symbol of power in many of their ceramics. In the Muisca religion in Altiplano Cundiboyacense, the jaguar was considered a sacred animal, and people dressed in jaguar skins during religious rituals. The skins were traded with peoples in the nearby Orinoquía Region. The name of the Muisca rulers, Muisca ruler Nemequene was derived from the Chibcha language, Chibcha words ''nymy'' and ''quyne'', meaning "force of the jaguar". Sculptures with "Olmec were-jaguar" motifs were found on the Yucatán Peninsula in Veracruz and Tabasco; they show stylized jaguars with half-human faces. In the later
