Mountain Gorilla
The mountain gorilla (''Gorilla beringei beringei'') is one of the two subspecies of the eastern gorilla. It is listed as endangered by the IUCN . There are two populations: One is found in the Virunga Mountains, Virunga volcanic mountains of Central Africa, Central/East Africa, within three National Parks: Mgahinga Gorilla National Park, Mgahinga, in southwest Uganda; Volcanoes National Park, Volcanoes, in northwest Rwanda; and Virunga National Park, Virunga, in the eastern Democratic Republic of Congo (DRC). The other population is found in Uganda's Bwindi Impenetrable National Park. Some primatologists speculate the Bwindi population is a separate subspecies, though no description has been finalized. The latest population count, released in 2019, revealed there to be approximately 1060 mountain gorillas in the wild. Evolution, taxonomy, and classification Mountain gorillas are descendants of ancestral monkeys and apes found in Africa and Arabia during the start of the Oligo ...

Paul Matschie
file: Paul Matschie (BerlLeben 1901-09).JPG, Paul Matschie Paul Matschie (11 August 1861, Brandenburg an der Havel – 7 March 1926, Friedenau) was a German zoologist. He studied mathematics and natural sciences at the Universities of University of Halle, Halle and University of Berlin, Berlin, afterwards working as an unpaid volunteer at the Museum für Naturkunde, Berlin Zoological Museum under Jean Cabanis (1816–1906). In 1892, he was in charge of the department of mammals at the museum, later becoming a curator (1895), and in 1902, attaining the title of professor. In 1924, he was appointed second director at the museum. During the years 1891–1893, he described 11 Species description, new species of reptiles. A species of gecko, ''Hemidactylus matschiei'' (Gustav Tornier, Tornier, 1901), is named in his honor. Matschie organized the fifth International Congress of Zoologists in Berlin and was for some years co-editor of the journal ''Natur und Haus''. Matschie's tree-k ...

Oligocene
The Oligocene ( ) is a geologic epoch (geology), epoch of the Paleogene Geologic time scale, Period that extends from about 33.9 million to 23 million years before the present ( to ). As with other older geologic periods, the rock beds that define the epoch are well identified but the exact dates of the start and end of the epoch are slightly uncertain. The name Oligocene was coined in 1854 by the German paleontologist Heinrich Ernst Beyrich from his studies of marine beds in Belgium and Germany. The name comes from Ancient Greek (''olígos'') 'few' and (''kainós'') 'new', and refers to the sparsity of Neontology, extant forms of Mollusca, molluscs. The Oligocene is preceded by the Eocene Epoch and is followed by the Miocene Epoch. The Oligocene is the third and final epoch of the Paleogene Period. The Oligocene is often considered an important time of transition, a link between the archaic world of the tropical Eocene and the more modern ecosystems of the Miocene. Major chang ...

Foraging
Foraging is searching for wild food resources. It affects an animal's fitness because it plays an important role in an animal's ability to survive and reproduce. Foraging theory is a branch of behavioral ecology that studies the foraging behavior of animals in response to the environment where the animal lives. Behavioral ecologists use economic models and categories to understand foraging; many of these models are a type of optimal model. Thus foraging theory is discussed in terms of optimizing a payoff from a foraging decision. The payoff for many of these models is the amount of energy an animal receives per unit time, more specifically, the highest ratio of energetic gain to cost while foraging. Foraging theory predicts that the decisions that maximize energy per unit time and thus deliver the highest payoff will be selected for and persist. Key words used to describe foraging behavior include ''resources'', the elements necessary for survival and reproduction which have a l ...

Diurnal Animal
Diurnality is a form of plant and 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 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 preferred pollinator ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Quadrupedal
Quadrupedalism is a form of Animal locomotion, locomotion in which animals have four legs that are used to weight-bearing, bear weight and move around. An animal or machine that usually maintains a four-legged posture and moves using all four legs is said to be a quadruped (from Latin ''quattuor'' for "four", and ''pes'', ''pedis'' for "foot"). Quadruped animals are found among both vertebrates and invertebrates. Quadrupeds vs. tetrapods Although the words ‘quadruped’ and ‘tetrapod’ are both derived from terms meaning ‘four-footed’, they have distinct meanings. A tetrapod is any member of the Linnaean taxonomy, taxonomic unit Tetrapoda (which is defined by descent from a specific four-limbed ancestor), whereas a quadruped actually uses four limbs for locomotion. Not all tetrapods are quadrupeds and not all quadrupedal animals are tetrapods; some arthropods are adapted for four-footed locomotion, such as the raptorial Mantodea, or mantises, and the Nymphalidae, or b ...

Terrestrial Animal
Terrestrial animals are animals that live predominantly or entirely on land (e.g. cats, chickens, ants, most spiders), as compared with aquatic animals, which live predominantly or entirely in the water (e.g. fish, lobsters, octopuses), and semiaquatic animals, which rely on both aquatic and terrestrial habitats (e.g. platypus, most amphibians). Some groups of insects are terrestrial, such as ants, butterflies, earwigs, cockroaches, grasshoppers and many others, while other groups are partially aquatic, such as mosquitoes and dragonflies, which pass their larval stages in water. Alternatively, terrestrial is used to describe animals that live on the ground, as opposed to arboreal animals that live in trees. Ecological subgroups The term "terrestrial" is typically applied to species that live primarily on or in the ground, in contrast to arboreal species, who live primarily in trees, even though the latter are actually a specialized subgroup of the terre ...

Ambam
Ambam is a town and commune in the Vallée-du-Ntem department, South Province, Cameroon on the border with Equatorial Guinea and Gabon. This frontier town is located approximately 220 km from Yaoundé and as of 2005 had a population of 41,089. Traditionally, it has traded with its neighbouring countries across the border. The Fang are the main ethnic group. History This town was once occupied by the Germans under the nation of Kamerun. The Germans built several administrative buildings in Ambam as it was of strategic importance. On 14 December 2000, the building proposal of a new road connecting Ambam to Eking on the Gabonese border was passed and signed on 2 February 2001. The building of the 27 kilometre road was funded by African Development Foundation (ADF) and the Government of Cameroon and was intended to improve socio-economic infrastructure and to improve the institutional capacities of the Ministries of Public Works (MINTP), Forestry and Wildlife (MINFOF), an ...

Kivu
Kivu is the name for a large region in the eastern Democratic Republic of the Congo that borders Lake Kivu. It was a ''Région'' (read 'province') of the country under the rule of Mobutu Sese Seko from 1966 to 1988. As an official ''Région'' in 1986 it was divided into the three "Sub-Regions" (''Sous-Régions'' in French) of: Nord-Kivu, Sud-Kivu and Maniema, Those three became the current provinces in the reorganization of 1988. The capital of the Kivu Region was in Bukavu, and the capitals of the three Sub-Regions were in Goma, Uvira and Kindu. History Kivu has been repeatedly subjected to major conflicts since the early 20th century. Under Belgian colonial rule, it was the site of several religious revolts such as the 1944 Kivu uprising. Following independence, it was a battleground of the Simba rebellion, First Congo War, and Second Congo War, and has been the site of an ongoing military conflict since the early 2000s. In 2025 substantial parts of the area came ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Temporalis Muscle
In anatomy, the temporalis muscle, also known as the temporal muscle, is one of the muscles of mastication (chewing). It is a broad, fan-shaped convergent muscle on each side of the head that fills the temporal fossa, superior to the zygomatic arch so it covers much of the temporal bone.Illustrated Anatomy of the Head and Neck, Fehrenbach and Herring, Elsevier, 2012, page 98 ''Temporal'' refers to the head's temples. Structure In humans, the temporalis muscle arises from the temporal fossa and the deep part of temporal fascia. This is a very broad area of attachment. It passes medial to the zygomatic arch. It forms a tendon which inserts onto the coronoid process of the mandible, with its insertion extending into the retromolar fossa posterior to the most distal mandibular molar.Human Anatomy, Jacobs, Elsevier, 2008, page 194 In other mammals, the muscle usually spans the dorsal part of the skull all the way up to the medial line. There, it may be attached to a sagittal cres ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Silverback Of Ntambara Group
Gorillas are primarily herbivorous, terrestrial great apes that inhabit the tropical forests of equatorial Africa. The genus ''Gorilla'' is divided into two species: the eastern gorilla and the western gorilla, and either four or five subspecies. The DNA of gorillas is highly similar to that of humans, from 96 to 99% depending on what is included, and they are the next closest living relatives to humans after the chimpanzees. Gorillas are the largest living primates, reaching heights between , weights between , and arm spans up to , depending on species and sex. They tend to live in troops, with the leader being called a silverback. The eastern gorilla is distinguished from the western by darker fur colour and some other minor morphological differences. Gorillas tend to live 35–40 years in the wild. Gorillas' natural habitats cover tropical or subtropical forest in Sub-Saharan Africa. Although their range covers a small percentage of Sub-Saharan Africa, gorillas cover a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
