African Leopard

Leopard---Panthera-pardus-copia

African Leopard (Panthera Pardus Pardus)

The African leopard (Panthera pardus pardus) is a leopard subspecies native to Africa. It is widely distributed in most of sub-Saharan Africa, but the historical range has been fragmented in the course of habitat conversion.[2]

Characteristics and geographical variation

African leopards exhibit great variation in coat color, depending on location and habitat. Coat color varies from pale yellow to deep gold or tawny, and sometimes black, and is patterned with black rosettes while the head, lower limbs and belly are spotted with solid black. Male leopards are larger, averaging 60 kg (130 lb) with 91 kg (201 lb) being the maximum weight attained by a male. Females weigh about 35 to 40 kg (77 to 88 lb) in average.

Between 1996 and 2000, 11 adult leopards were radio-collared on Namibian farmlands. Males weighed 37.5 to 52.3 kg (83 to 115 lb) only, and females 24 to 33.5 kg (53 to 74 lb).[3]

Leopards inhabiting the mountains of the Cape Provinces appear physically different from leopards further north. Their average weight may be only half that of the more northerly leopard.[4]

Distribution and habitat

African leopards used to occur in most of sub-Saharan Africa, occupying both rainforest and arid desert habitats. They were found in all habitats with annual rainfall above 50 mm (2.0 in), and can penetrate areas with less than this amount of rainfall along river courses. They range exceptionally up to 5,700 m (18,700 ft), have been sighted on high slopes of the Ruwenzori and Virunga volcanoes, and observed when drinking thermal water 37 °C (99 °F) in the Virunga National Park.[5]

They appear to be successful at adapting to altered natural habitat and settled environments in the absence of intense persecution. There were many records of their presence near major cities. But already in the 1980s, they have become rare throughout much of West Africa.[6] Now, they remain patchily distributed within historical limits.[2]

In North Africa, a tiny relict population, the Barbary leopard, persists in the Atlas Mountains of Morocco.[7]

African leopards inhabited a wide range of habitats within Africa, from mountainous forests to grasslands and savannahs, excluding only extremely sandy desert. They are most at risk in areas of semi-desert, where scarce resources often result in conflict with nomadic farmers and their livestock.

Ecology and behavior

Leopards are generally most active between sunset and sunrise, and kill more prey at this time.[8] In Kruger National Park, male leopards and female leopards with cubs were relatively more active at night than solitary females. The highest rates of daytime activity were recorded for leopards using thorn thickets during the wet season, when impala also used them.[9]

They have an exceptional ability to adapt to changes in prey availability, and have a very broad diet. Small prey are taken where large ungulates are less common. The known prey of leopards ranges from dung beetles to adult elands, which can reach 900 kg (2,000 lb).[5] In sub-Saharan Africa, at least 92 prey species have been documented in their diet including rodentsbirds, small and large antelopeshyraxes and hares, and arthropods. They generally focus their hunting activity on locally abundant medium-sized ungulate species in the 20 to 80 kg (44 to 176 lb) range, while opportunistically taking other prey. Average intervals between ungulate kills range from seven[9] to 12–13 days.[8]

In the Serengeti National Park, leopards were radio-collared for the first time in the early 1970s. Their hunting at night was difficult to watch; the best time for observing them was after dawn. Of their 64 daytime hunts only three were successful. In this woodland area, they preyed mostly on impala, both adult and young, and caught some Thomson’s gazelles in the dry season. Occasionally, they successfully hunted warthogdik-dikreedbuckduikersteenbokwildebeest and topi calves, jackalhareguinea fowl and starling. They were less successful in hunting zebraskongonisgiraffesmongoosesgenetshyrax and small birds. Scavenging from the carcasses of large animals made up a small proportion of their food.[10] In tropical rainforest in Central Africa, their diet consists of duikers and small primates. Some individual leopards have shown a strong preference for pangolins and porcupines.[11]

Leopards often cache large kills in trees, a behavior for which great strength is required. There have been several observations of leopards hauling carcasses of young giraffe, estimated to weigh up to 125 kg (276 lb), i.e. 2–3 times the weight of the leopard, up to 5.7 m (19 ft) into trees.[8]

Their diet includes reptiles, and they will occasionally take domestic livestock when other food is scarce. Leopards are very stealthy and like to stalk close and run a relatively short distance after their prey. They kill through suffocation by grabbing their prey by the throat and biting down with their powerful jaws. They rarely fight other predators for their food.

Threats

Throughout Africa, the major threats to leopards are habitat conversion and intense persecution, especially in retribution for real and perceived livestock loss.[12]

The impact of trophy hunting on populations is unclear, but may have impacts at the demographic and population level, especially when females are shot. In Tanzania, only males are allowed to be hunted, but females comprised 28.6% of 77 trophies shot between 1995 and 1998.[13] Removing an excessively high number of males may produce a cascade of deleterious effects on the population. Although male leopards provide no parental care to cubs, the presence of the sire allows mothers to raise cubs with a reduced risk of infanticide by foreign males. There are few reliable observations of infanticide in leopards but new males entering the population are likely to kill existing cubs.[14]

Analysis of leopard scats and camera trapping surveys in contiguous forest landscapes in the Congo Basin revealed a high dietary niche overlap and an exploitative competition between leopards and bushmeat hunters. With increasing proximity to settlements and concomitant human hunting pressure, leopards exploit smaller prey and occur at considerably reduced population densities. In the presence of intensive bushmeat hunting surrounding human settlements, leopards appear entirely absent.[15]

Conservation

Panthera pardus is listed in CITES Appendix I.[2]
