Leopards
The leopard (''Panthera pardus'') is one of the five extant cat species in the genus ''Panthera''. It has a pale yellowish to dark golden fur with dark spots grouped in rosettes. Its body is slender and muscular reaching a length of with a long tail and a shoulder height of . Males typically weigh , and females . The leopard was first described in 1758, and several subspecies were proposed in the 19th and 20th centuries. Today, eight subspecies are recognised in its wide range in Africa and Asia. It initially evolved in Africa during the Early Pleistocene, before migrating into Eurasia around the Early–Middle Pleistocene transition. Leopards were formerly present across Europe, but became extinct in the region at around the end of the Late Pleistocene-early Holocene. The leopard is adapted to a variety of habitats ranging from rainforest to steppe, including arid and montane areas. It is an opportunistic predator, hunting mostly ungulates and primates. It relies on its ...

European Leopard
Leopards have a long history in Europe, spanning from the Early-Middle Pleistocene transition, around 1.2-0.6 million years ago, until the end of the Late Pleistocene, around 12,000 years ago, and possibly later into the early Holocene. Remains of leopards have been found across Europe, from the Iberian Peninsula to the Caucasus. Taxonomy and genetics The proposed Late Pleistocene European leopard subspecies ''Panthera pardus spelaea'' was first described as ''Felis pardus spelaea'' by Emil Bächler in 1936. Several fossil bones from the Early, Middle and Late Pleistocene were described and have been proposed as different leopard subspecies: * ''Panthera pardus antiqua'' * ''Panthera pardus begoueni'' * ''Panthera pardus sickenbergi'' * ''Panthera pardus vraonensis'' Analysis of mitochondrial genomes from Late Pleistocene European leopard specimens found in Baumannshöhle in Germany, dating to around 40,000 years ago, found that they shared a mitochondrial genome lineag ...

African Leopard
The African leopard (''Panthera pardus pardus'') is the nominate subspecies of the leopard, native to many countries in Africa. It is widely distributed in most of sub-Saharan Africa, but the historical range has been Habitat fragmentation, fragmented in the course of Habitat destruction, habitat conversion. Leopards have also been recorded in North Africa as well. Taxonomy ''Felis pardus'' was the scientific name used by Carl Linnaeus in the 10th edition of Systema Naturae, 10th edition of ''Systema Naturae'' in 1758. His description was based on descriptions by earlier naturalists such as Conrad Gessner. He assumed that the leopard occurred in India. In the 18th and 19th centuries, several naturalists described various leopard skins and skulls from Africa, including: * ''Felis pardus panthera'' proposed by Johann Christian Daniel von Schreber in 1778 based on descriptions by earlier naturalists * ''Felis leopardus'' var. ''melanotica'' by Albert Günther in 1885 from the Cape ...

Panthera
''Panthera'' is a genus within the family (biology), family Felidae, and one of two extant genera in the subfamily Pantherinae. It contains the largest living members of the cat family. There are five living species: the jaguar, leopard, lion, snow leopard and tiger. Numerous extinct species are also named, including the Panthera spelaea, cave lion and American lion. Etymology The word derives from Classical Latin , itself from the Ancient Greek (). Characteristics In ''Panthera'' species, the dorsal profile of the skull is flattish or evenly convex. The frontal interOrbit (anatomy), orbital area is not noticeably elevated, and the area behind the elevation is less steeply sloped. The basic Cranial cavity, cranial axis is nearly horizontal. The inner chamber of the Auditory bulla, bullae is large, the outer small. The partition between them is close to the external auditory meatus. The convexly rounded chin is sloping. All ''Panthera'' species have an incompletely ossified h ...

Rosette (zoology)
A rosette is a rose-like Animal markings, marking or formation found on the fur and skin of some animals, particularly Felidae, cats. Rosettes are used to camouflage the animal, either as a defense mechanism or as a stalking tool. Predators use their rosettes to simulate the different shifting of shadows and shade, helping the animals to remain hidden from their prey. Rosettes can be grouped in clusters around other spots, or may appear as blotches on the fur. Leopard The leopard (''Panthera pardus'') has a wide variety of coat coloration. On each color variation, the leopard has rosette patterns on their backs, flanks, and limbs. They also have patterns that are considered to be spots and not rosettes on their heads, stomach, and limbs. Jaguar Like the leopard, the jaguar (''Panthera onca'') has a wide variety of coat coloration. The jaguar can have a coat in colors ranging from white to black with the most common residing in brownish yellow area. These big cats have rose ...

Maasai Mara National Reserve
Maasai Mara, sometimes also spelt Masai Mara and locally known simply as The Mara, is a large national game reserve in Narok County, Kenya, contiguous with the Serengeti National Park in Tanzania. It is named in honour of the Maasai people, the ancestral inhabitants of the area, who migrated to the area from the Nile Basin. Their description of the area when looked at from afar: "Mara" means "spotted" in the Maa language because of the short bushy trees which dot the landscape. Maasai Mara is one of the wildlife conservation and wilderness areas in Africa, with its populations of lions, leopards, cheetahs and African bush elephants. It also hosts the Great Migration, which secured it as one of the Seven Natural Wonders of Africa, and as one of the ten Wonders of the World. The Great Migration usually happens in July depending on weather as the wildebeest moves in large numbers crossing the Mara River from Tanzania. The Greater Mara ecosystem encompasses areas known as the M ...

Kenya
Kenya, officially the Republic of Kenya, is a country located in East Africa. With an estimated population of more than 52.4 million as of mid-2024, Kenya is the 27th-most-populous country in the world and the 7th most populous in Africa. Kenya's capital and largest city is Nairobi. Its second-largest and oldest city is Mombasa, a major port city located on Mombasa Island. Other major cities within the country include Kisumu, Nakuru & Eldoret. Going clockwise, Kenya is bordered by South Sudan to the northwest (though much of that border includes the disputed Ilemi Triangle), Ethiopia to the north, Somalia to the east, the Indian Ocean to the southeast, Tanzania to the southwest, and Lake Victoria and Uganda to the west. Kenya's geography, climate and population vary widely. In western, rift valley counties, the landscape includes cold, snow-capped mountaintops (such as Batian, Nelion and Point Lenana on Mount Kenya) with vast surrounding forests, wildlife and ...

Rainforest
Rainforests are forests characterized by a closed and continuous tree Canopy (biology), canopy, moisture-dependent vegetation, the presence of epiphytes and lianas and the absence of wildfire. Rainforests can be generally classified as tropical rainforests or temperate rainforests, but other types have been described. Estimates vary from 40% to 75% of all biotic community, biotic species being Indigenous (ecology), indigenous to the rainforests. There may be many millions of species of plants, insects and microorganisms still undiscovered in tropical rainforests. Tropical rainforests have been called the "jewels of the Earth" and the "medicine chest (idiom), world's largest pharmacy", because over one quarter of natural medicines have been discovered there. Rainforests as well as endemic rainforest species are rapidly disappearing due to #Deforestation, deforestation, the resulting habitat loss and air pollution, pollution of the atmosphere. Definition Rainforests are cha ...

Habitat Loss
Habitat destruction (also termed habitat loss or habitat reduction) occurs when a natural habitat is no longer able to support its native species. The organisms once living there have either moved elsewhere, or are dead, leading to a decrease in biodiversity and Abundance (ecology), species numbers. Habitat destruction is in fact the leading cause of biodiversity loss and species extinction worldwide. Humans contribute to habitat destruction through the Exploitation of natural resources, use of natural resources, agriculture, industrial production and urbanization (urban sprawl). Other activities include mining, logging and trawling. Environmental factors can contribute to habitat destruction more indirectly. Geological processes, climate change, introduced species, introduction of invasive species, ecosystem nutrient depletion, water pollution, water and noise pollution are some examples. Loss of habitat can be preceded by an initial habitat fragmentation. Fragmentation and lo ...

IUCN Red List
The International Union for Conservation of Nature (IUCN) Red List of Threatened Species, also known as the IUCN Red List or Red Data Book, founded in 1964, is an inventory of the global conservation status and extinction risk of biological species. A series of Regional Red Lists, which assess the risk of extinction to species within a political management unit, are also produced by countries and organizations. The goals of the Red List are to provide scientifically based information on the status of species and subspecies at a global level, to draw attention to the magnitude and importance of threatened biodiversity, to influence national and international policy and decision-making, and to provide information to guide actions to conserve biological diversity. Major species assessors include BirdLife International, the Institute of Zoology (the research division of the Zoological Society of London), the World Conservation Monitoring Centre, and many Specialist Groups w ...

Vulnerable Species
A vulnerable species is a species which has been Conservation status, categorized by the International Union for Conservation of Nature as being threatened species, threatened with extinction unless the circumstances that are threatened species, threatening its survival and reproduction improve. Vulnerability is mainly caused by habitat loss or destruction of the species' home. Vulnerable habitat or species are monitored and can become increasingly threatened. Some species listed as "vulnerable" may be common in captivity (animal), captivity, an example being the military macaw. In 2012 there were 5,196 animals and 6,789 plants classified as vulnerable, compared with 2,815 and 3,222, respectively, in 1998. Practices such as cryoconservation of animal genetic resources have been enforced in efforts to conserve vulnerable breeds of livestock specifically. Criteria The International Union for Conservation of Nature uses several criteria to enter species in this category. A taxon ...

Sexual Maturity
Sexual maturity is the capability of an organism to reproduce. In humans, it is related to both puberty and adulthood. ''Puberty'' is the biological process of sexual maturation, while ''adulthood'', the condition of being socially recognized as an independent person capable of giving consent and taking responsibility, generally implies sexual maturity (certain disorders of sexual development notwithstanding), but depends on other criteria, defined by specific cultural expectations. Most multicellular organisms are unable to sexually reproduce at birth (animals) or germination (e.g. plants): depending on the species, it may be days, weeks, or years until they have developed enough to be able to do so; in addition, certain cues may trigger an organism to become sexually mature. These may be external, such as drought, or fire, that triggers sexual maturation of certain plants, or internal, such as percentage of body fat (certain animals). Internal cues are not to be confused ...

Solitary Animal
Sociality is the degree to which individuals in an animal population tend to associate in social groups (gregariousness) and form cooperative societies. Sociality is a survival response to evolutionary pressures. For example, when a mother wasp stays near her larvae in the nest, parasites are less likely to eat the larvae. Biologists suspect that pressures from parasites and other predators selected this behavior in wasps of the family Vespidae. This wasp behaviour evidences the most fundamental characteristic of animal sociality: parental investment. Parental investment is any expenditure of resources (time, energy, social capital) to benefit one's offspring. Parental investment detracts from a parent's capacity to invest in future reproduction and aid to kin (including other offspring). An animal that cares for its young but shows no other sociality traits is said to be ''subsocial''. An animal that exhibits a high degree of sociality is called a ''social animal''. The ...
