White-bellied Robin-chat
The white-bellied robin-chat (''Cossyphicula roberti'') is a species of bird in the Old World flycatcher family Muscicapidae. It is found across the Western High Plateau, Bioko and the Albertine Rift montane forests. Its natural habitats are subtropical or tropical moist lowland forest and subtropical or tropical moist montane forest. A molecular phylogenetic study published in 2023 found that the white-bellied robin-chat was sister A sister is a woman or a girl who shares parents or a parent with another individual; a female sibling. The male counterpart is a brother. Although the term typically refers to a familial relationship, it is sometimes used endearingly to ref ... to the mountain robin-chat.

Hermann Grote
Hermann Grote (7 July 1882 – 12 August 1951) was a German ornithologist known for his studies of African avifauna. While serving as a director of a sisal plantation in German East Africa, he published papers on the local avifauna (from 1909 to 1913). As a Russian POW during WWI, he learned Russian, a skill set he subsequently used to translate Russian ornithological works into German. During his career, he was associated with ornithological research performed at the Museum für Naturkunde in Berlin.1952 .1 Obituaries 223 - University of New Mexico obituary of Hermann Grote In 1923 he was elected a corresponding fellow of the |
Molecular Phylogenetic
Molecular phylogenetics () is the branch of phylogeny that analyzes genetic, hereditary molecular differences, predominantly in DNA sequences, to gain information on an organism's evolutionary relationships. From these analyses, it is possible to determine the processes by which diversity among species has been achieved. The result of a molecular phylogenetic analysis is expressed in a phylogenetic tree. Molecular phylogenetics is one aspect of molecular systematics, a broader term that also includes the use of molecular data in taxonomy and biogeography. Molecular phylogenetics and molecular evolution correlate. Molecular evolution is the process of selective changes (mutations) at a molecular level (genes, proteins, etc.) throughout various branches in the tree of life (evolution). Molecular phylogenetics makes inferences of the evolutionary relationships that arise due to molecular evolution and results in the construction of a phylogenetic tree.

Afromontane Endemic Bird Species
The Afromontane regions are subregions of the Afrotropical realm, one of the Earth's eight biogeographic realms, covering the plant and animal species found in the mountains of Africa and the southern Arabian Peninsula. The Afromontane regions of Africa are discontinuous, separated from each other by lower-lying areas, and are sometimes referred to as the Afromontane archipelago, as their distribution is analogous to a series of sky islands. Geography Afromontane communities occur above elevation near the equator, and as low as elevation in the Knysna-Amatole montane forests of South Africa. Afromontane forests are generally cooler and more humid than the surrounding lowlands. The Afromontane archipelago mostly follows the East African Rift from the Red Sea to Zimbabwe, with the largest areas in the Ethiopian Highlands, the Albertine Rift Mountains of Uganda, Rwanda, Burundi, Democratic Republic of the Congo, and Tanzania, and the Eastern Arc highlands of Kenya and Tanzania. ...

Birds Of Central Africa
Birds are a group of warm-blooded vertebrates constituting the class Aves (), characterised by feathers, toothless beaked jaws, the laying of hard-shelled eggs, a high metabolic rate, a four-chambered heart, and a strong yet lightweight skeleton. Birds live worldwide and range in size from the bee hummingbird to the common ostrich. There are over 11,000 living species and they are split into 44 orders. More than half are passerine or "perching" birds. Birds have wings whose development varies according to species; the only known groups without wings are the extinct moa and elephant birds. Wings, which are modified forelimbs, gave birds the ability to fly, although further evolution has led to the loss of flight in some birds, including ratites, penguins, and diverse endemic island species. The digestive and respiratory systems of birds are also uniquely adapted for flight. Some bird species of aquatic environments, particularly seabirds and some waterbirds, have furth ...

Cossyphicula
''Cossyphicula'' is a genus of passerine birds belonging to the Old World flycatcher family Muscicapidae that are found in Sub-Saharan Africa. Taxonomy The genus ''Cossyphicula'' was introduced in 1934 by the German ornithologist Hermann Grote to accommodate the white-bellied robin-chat which is therefore considered as the type species. The name is a diminutive of the genus name ''Cossypha'' introduced for the robin-chats by Nicholas Aylward Vigors in 1825. Species The genus contains two species: * White-bellied robin-chat, ''Cossyphicula roberti'' * Mountain robin-chat, ''Cossyphicula isabellae'' (formerly placed in ''Cossypha ''Cossypha'' are small insectivorous birds, with most species called robin-chats. They were formerly in the thrush (bird), thrush family Turdidae, but are now more often treated as part of the Old World flycatcher Muscicapidae. These are African ...'')

Mountain Robin-chat
The mountain robin-chat (''Cossyphicula isabellae'') is a species of bird in the Old World flycatcher family Muscicapidae. It is native to the Western High Plateau. Its natural habitat is subtropical or tropical moist montane forests. A molecular phylogenetic study published in 2023 found that the mountain robin-chat was sister to the white-bellied robin-chat. Based on this result the mountain robin-chat was moved from the genus ''Cossypha'' to the genus ''Cossyphicula ''Cossyphicula'' is a genus of passerine birds belonging to the Old World flycatcher family Muscicapidae that are found in Sub-Saharan Africa.

Sister Taxon
In phylogenetics, a sister group or sister taxon, also called an adelphotaxon, comprises the closest relative(s) of another given unit in an evolutionary tree. Definition The expression is most easily illustrated by a cladogram: Taxon A and taxon B are sister groups to each other. Taxa A and B, together with any other extant or extinct descendants of their most recent common ancestor (MRCA), form a monophyletic group, the clade AB. Clade AB and taxon C are also sister groups. Taxa A, B, and C, together with all other descendants of their MRCA form the clade ABC. The whole clade ABC is itself a subtree of a larger tree which offers yet more sister group relationships, both among the leaves and among larger, more deeply rooted clades. The tree structure shown connects through its root to the rest of the universal tree of life. In cladistic standards, taxa A, B, and C may represent specimens, species, genera, or any other taxonomic units. If A and B are at the same taxonomic ...

Montane Forest
Montane ecosystems are found on the slopes of mountains. The alpine climate in these regions strongly affects the ecosystem because temperatures lapse rate, fall as elevation increases, causing the ecosystem to stratify. This stratification is a crucial factor in shaping plant community, biodiversity, metabolic processes and ecosystem dynamics for montane ecosystems. Dense montane forests are common at moderate elevations, due to moderate temperatures and high rainfall. At higher elevations, the climate is harsher, with lower temperatures and higher winds, preventing the growth of trees and causing the plant community to transition to montane grasslands and shrublands or alpine tundra. Due to the unique climate conditions of montane ecosystems, they contain increased numbers of endemic species. Montane ecosystems also exhibit variation in ecosystem services, which include carbon storage and water supply. Life zones As elevation increases, the alpine climate, climate becomes co ...

Subtropical Or Tropical Moist Lowland Forest
Tropical and subtropical moist broadleaf forests (TSMF), also known as tropical moist forest, is a subtropical and tropical forest habitat type defined by the World Wide Fund for Nature (WWF). Description TSMF is generally found in large, discontinuous patches centered on the equatorial belt and between the Tropic of Cancer and Tropic of Capricorn. TSMF are characterized by low variability in annual temperature and high levels of rainfall of more than annually. Forest composition is dominated by evergreen and semi-deciduous tree species. These forests are home to more species than any other terrestrial ecosystem on Earth: Half of the world's species may live in these forests, where a square kilometer may be home to more than 1,000 tree species. These forests are found around the world, particularly in the Indo-Malayan Archipelago, the Amazon Basin, and the African Congo Basin. The perpetually warm, wet climate makes these environments more productive than any other t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Habitat
In ecology, habitat refers to the array of resources, biotic factors that are present in an area, such as to support the survival and reproduction of a particular species. A species' habitat can be seen as the physical manifestation of its ecological niche. Thus "habitat" is a species-specific term, fundamentally different from concepts such as Biophysical environment, environment or vegetation assemblages, for which the term "habitat-type" is more appropriate. The physical factors may include (for example): soil, moisture, range of temperature, and Luminous intensity, light intensity. Biotic index, Biotic factors include the availability of food and the presence or absence of Predation, predators. Every species has particular habitat requirements, habitat generalist species are able to thrive in a wide array of environmental conditions while habitat specialist species require a very limited set of factors to survive. The habitat of a species is not necessarily found in a ge ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
