Korup National Park
Korup National Park is in the Southwest Province of Cameroon and extends over 1,260 km2 of mostly undisturbed primary forest. It is reputedly one of Africa’s oldest and richest tropical forests in terms of floral and faunal diversity. It is the most accessible rainforest national park in Cameroon with basic lodging infrastructure and a large network of trails open to visitors. The park is a popular birdwatching destination and famous for primate viewing (including species such as the drill, Preuss's red colobus, red-eared guenon and Nigeria chimpanzee). Researchers from various disciplines have been conducting biological studies in Korup for over three decades, generating a wealth of information on rainforest ecosystems. Location The Korup National Park is in the Southwest Province of Cameroon between in ahaus N and 8°42’ to 9°16’ E. It is 50 km inland from the Bight of Biafra, 20 km from the edge of the mangrove swamps of the Rio Del Rey estuary and partiall ...

Southwest Province, Cameroon
The Southwest Region or South-West Region () is a region in Cameroon. Its capital is Buea. , its population was 1,553,320. Along with the Northwest Region, it is one of the two Anglophone (English-speaking) regions of Cameroon. Various Ambazonian nationalist and separatist factions regard the ''Sud-Ouest'' region as being distinct as a polity from Cameroon. Administration The region is divided into six divisions or departments: Fako, Koupé-Manengouba, Lebialem, Manyu, Meme, and Ndian. These are in turn broken down into subdivisions. Presidentially appointed senior divisional officers () and subdivisional officers () govern each respectively. Ambazonian separatism Separatists from the Ambazonia administration regard both the Nord-Ouest (Northwest) and Sud-Ouest (Southwest) regions as being constituent components of their envisaged breakaway state. Geography The region was notable for having the first English-speaking university in Cameroon (the University of Buea). Towns in ...

Oban Hills
The Oban Hills are a range of hills in Cross River State, Nigeria. They lie within the Oban Hills Division of the Cross River National Park. Geography The hills are rugged, rising from in the river valleys to over in the mountains. The soils are highly vulnerable to leaching and erosion where stripped of plant cover. The rainy season lasts from March to November, with annual rainfall of over 3,500 mm. The northern part is drained by the Cross River and its tributaries. The southern parts are drained by the Calabar, Kwa and Korup rivers. Land use The Oban hills, which take their name from the small town of Oban to the south, contain the largest area of unexploited lowland rain forest in Nigeria. It is possible that at one time the region was home to more people, perhaps being depopulated due to its proximity to the slave trading center of Calabar, and that the forest may actually be fairly recent growth. A 1988 report said that the remaining patches of forest on mounta ...

Nocturnal
Nocturnality is an animal behavior characterized by being active during the night and sleeping during the day. The common adjective is "nocturnal", versus diurnal meaning the opposite. Nocturnal creatures generally have highly developed senses of hearing, smell, and specially adapted eyesight. Some animals, such as cats and ferrets, have eyes that can adapt to both low-level and bright day levels of illumination (see metaturnal). Others, such as bushbabies and (some) bats, can function only at night. Many nocturnal creatures including tarsiers and some owls have large eyes in comparison with their body size to compensate for the lower light levels at night. More specifically, they have been found to have a larger cornea relative to their eye size than diurnal creatures to increase their : in the low-light conditions. Nocturnality helps wasps, such as ''Apoica flavissima'', avoid hunting in intense sunlight. Diurnal animals, including squirrels and songbirds, are active du ...

Diurnality
Diurnality is a form of plant and ethology, animal behavior characterized by activity during daytime, with a period of sleeping or other inactivity at night. The common adjective used for daytime activity is "diurnal". The timing of activity by an animal depends on a variety of environmental factors such as the temperature, the ability to gather food by sight, the risk of predation, and the time of year. Diurnality is a cycle of activity within a 24-hour period; cyclic activities called circadian rhythms are endogenous cycles not dependent on external cues or environmental factors except for a zeitgeber. Animals active during twilight are crepuscular, those active during the night are nocturnal and animals active at sporadic times during both night and day are cathemerality, cathemeral. Plants that open their flowers during the daytime are described as diurnal, while those that bloom during nighttime are nocturnal. The timing of flower opening is often related to the time at which ...

Butterflies
Butterflies are insects in the macrolepidopteran clade Rhopalocera from the Order (biology), order Lepidoptera, which also includes moths. Adult butterflies have large, often brightly coloured wings, and conspicuous, fluttering flight. The group comprises the large superfamily (zoology), superfamily Papilionoidea, which contains at least one former group, the skippers (formerly the superfamily "Hesperioidea"), and the most recent analyses suggest it also contains the moth-butterflies (formerly the superfamily "Hedyloidea"). Butterfly fossils date to the Paleocene, about 56 million years ago. Butterflies have a four-stage life cycle, as like most insects they undergo Holometabolism, complete metamorphosis. Winged adults lay eggs on the food plant on which their larvae, known as caterpillars, will feed. The caterpillars grow, sometimes very rapidly, and when fully developed, pupate in a chrysalis. When metamorphosis is complete, the pupal skin splits, the adult insect climbs o ...

Amphibians
Amphibians are four-limbed and ectothermic vertebrates of the class Amphibia. All living amphibians belong to the group Lissamphibia. They inhabit a wide variety of habitats, with most species living within terrestrial, fossorial, arboreal or freshwater aquatic ecosystems. Thus amphibians typically start out as larvae living in water, but some species have developed behavioural adaptations to bypass this. The young generally undergo metamorphosis from larva with gills to an adult air-breathing form with lungs. Amphibians use their skin as a secondary respiratory surface and some small terrestrial salamanders and frogs lack lungs and rely entirely on their skin. They are superficially similar to reptiles like lizards but, along with mammals and birds, reptiles are amniotes and do not require water bodies in which to breed. With their complex reproductive needs and permeable skins, amphibians are often ecological indicators; in recent decades there has been a dramatic decli ...

Reptiles
Reptiles, as most commonly defined are the animals in the Class (biology), class Reptilia ( ), a paraphyletic grouping comprising all sauropsid, sauropsids except birds. Living reptiles comprise turtles, crocodilians, Squamata, squamates (lizards and snakes) and rhynchocephalians (tuatara). As of March 2022, the Reptile Database includes about 11,700 species. In the traditional Linnaean taxonomy, Linnaean classification system, birds are considered a separate class to reptiles. However, crocodilians are more closely related to birds than they are to other living reptiles, and so modern Cladistics, cladistic classification systems include birds within Reptilia, redefining the term as a clade. Other cladistic definitions abandon the term reptile altogether in favor of the clade Sauropsida, which refers to all amniotes more closely related to modern reptiles than to mammals. The study of the traditional reptile Order (biology), orders, historically combined with that of modern amphi ...

Gymnosiphon
''Gymnosiphon'' (yellowseed) is a genus of monocotyledonous flowering plants from the yam order. Like most of the other members of the family in which the plant is placed (Burmanniaceae), ''Gymnosiphon'' is entirely myco-heterotrophic genus that does not contain chlorophyll and respectively does not perform photosynthesis. ''Gymnosiphon'' is distributed across the moist, tropical regions of Asia, America and Africa. The plant has very small size and thin stems. Leaves are rudimentary and with appearance like scales or bracts. Its flowers are white in color, pale and solitary or sometimes collected in tiny inflorescences of few depending on the species. They are also actinomorphic with three larger outer tepals and three more inner and smaller ones. Phylogenetically ''Gymnosiphon'' is placed in the clade of Burmanniaceae Burmanniaceae is a family of flowering plants, consisting of 99 species of herbaceous plants in eight genera. Description These plants are annual or per ...

Herbaceous Layer
Stratification in the field of ecology refers to the vertical layering of a habitat; the arrangement of vegetation in layers. It classifies the layers (sing. ''stratum'', pl. ''strata'') of vegetation largely according to the different heights to which their plants grow. The individual layers are inhabited by different animal and plant communities (stratozones). Vertical structure in terrestrial plant habitats The following layers are generally distinguished: forest floor (root and moss layers), herb, shrub, understory and canopy layers. These vegetation layers are primarily determined by the height of their individual plants, the different elements may however have a range of heights. The actual layer is characterised by the height range in which the vast majority of photosynthetic organs (predominantly leaves) are found. Taller species will have part of their shoot system in the underlying layers. In addition to the above-ground stratification there is also a “root layer”. ...
