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 P.O.W. of the Russians during World War I, he learned the Russian language, 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 [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Songbird
A songbird is a bird belonging to the suborder Passeri of the perching birds (Passeriformes). Another name that is sometimes seen as the scientific or vernacular name is Oscines, from Latin ''oscen'', "songbird". The Passeriformes contains 5000 or so speciesEdwards, Scott V. and John Harshman. 2013. Passeriformes. Perching Birds, Passerine Birds.

Songbirds form one of the two major lineages of extant perching birds (~4000 species), the other being the Tyranni (~1000 species), which are most diverse in the Neotropics and absent from many parts of the world. The Tyranni have a simpler syrinx musculature, and while their vocalizations are often just as complex and striking as thos ...

Bulbul
The bulbuls are members of a family, Pycnonotidae, of medium-sized passerine songbirds, which also includes greenbuls, brownbuls, leafloves, and bristlebills. The family is distributed across most of Africa and into the Middle East, tropical Asia to Indonesia, and north as far as Japan. A few insular species occur on the tropical islands of the Indian Ocean. There are 160 species in 32 genera. While different species are found in a wide range of habitats, the African species are predominantly found in rainforest, whereas Asian bulbuls are predominantly found in more open areas. Taxonomy The family Pycnonotidae was introduced by the English zoologist George Robert Gray in 1840 as a subfamily Pycnonotinae of the thrush family Turdidae. The Arabic word ''bulbul'' (بلبل) is sometimes used to refer to the "nightingale" as well as the bulbul, but the English word ''bulbul'' refers to the birds discussed in this article.

Usambara Mountains
The Usambara Mountains of northeastern Tanzania in tropical East Africa, comprise the easternmost ranges of the Eastern Arc Mountains. The ranges of approximately long and about half that wide, are situated in the Lushoto District of the Tanga Region. They were formed nearly two million years ago by faulting and uplifting, and are composed of Precambrian metamorphic rocks. They are split into two sub-ranges; the West Usambaras being higher than the East Usambaras, which are nearer the coast and receive more rainfall. The mountains are clad in virgin tropical rainforest which has been isolated for a long period and they are a centre of endemism. Historically they were inhabited by Bantu, Shambaa, and Maasai people but in the eighteenth century, a Shambaa kingdom was founded by Mbegha. The kingdom eventually fell apart after a succession struggle in 1862. German colonists settled in the area which was to become German East Africa, and after World War I it became part of the ...

Nguru Mountains
The Nguru Mountains are a mountain range in Morogoro Region, Tanzania, Africa. The Nguru Mountains are part of the Eastern Arc Mountains. The mountains are predominantly covered with rainforest, home to 83 species of birds (Romdal 2001) and African violets. There are a number of forest reserves in the mountains. Geography The Nguru Mountains cover an area of 1672.90 km². The highest elevation is 2400 meters in Nguru South. The range runs roughly northeast-southwest, and is split by the valley of the Mjonga River, a tributary of the Wami River. The range lies in the watershed of the Wami. The plain of the Wami and its tributary the Mkata lies to the southeast and east. The Uluguru Mountains lie to the southeast across the plain. The Ukaguru Mountains lie to the southwest, and the Nguu Mountains lie to the north; both ranges are separated from the Nguru Mountains by low hills. More hilly country separates the Maasai Steppe the northwest. Climate The Nguru mountains interce ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Habitat
In ecology, the term habitat summarises the array of resources, physical and 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 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 light intensity. Biotic factors will include the availability of food and the presence or absence of predators. Every species has particular habitat requirements, with habitat generalist species able to thrive in a wide array of environmental conditions while habitat specialist species requiring a very limited set of factors to survive. The habitat of a species is not necessarily found in a geographical area, it can be the interior ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Forest
A forest is an area of land dominated by trees. Hundreds of definitions of forest are used throughout the world, incorporating factors such as tree density, tree height, land use, legal standing, and ecological function. The United Nations' Food and Agriculture Organization (FAO) defines a forest as, "Land spanning more than 0.5 hectares with trees higher than 5 meters and a canopy cover of more than 10 percent, or trees able to reach these thresholds ''in situ''. It does not include land that is predominantly under agricultural or urban use." Using this definition, '' Global Forest Resources Assessment 2020'' (FRA 2020) found that forests covered , or approximately 31 percent of the world's land area in 2020. Forests are the predominant terrestrial ecosystem of Earth, and are found around the globe. More than half of the world's forests are found in only five countries (Brazil, Canada, China, Russia, and the United States). The largest share of forests (45 percent) are in th ...

Shrubland
Shrubland, scrubland, scrub, brush, or bush is a plant community characterized by vegetation dominated by shrubs, often also including grasses, herbs, and geophytes. Shrubland may either occur naturally or be the result of human activity. It may be the mature vegetation type in a particular region and remain stable over time, or a transitional community that occurs temporarily as the result of a disturbance, such as fire. A stable state may be maintained by regular natural disturbance such as fire or browsing. Shrubland may be unsuitable for human habitation because of the danger of fire. The term was coined in 1903. Shrubland species generally show a wide range of adaptations to fire, such as heavy seed production, lignotubers, and fire-induced germination. Botanical structural form In botany and ecology a shrub is defined as a much-branched woody plant less than 8 m high and usually with many stems. Tall shrubs are mostly 2–8 m high, small shrubs 1–2 m high and su ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Conspecific
Biological specificity is the tendency of a characteristic such as a behavior or a biochemical variation to occur in a particular species. Biochemist Linus Pauling stated that "Biological specificity is the set of characteristics of living organisms or constituents of living organisms of being special or doing something special. Each animal or plant species is special. It differs in some way from all other species...biological specificity is the major problem about understanding life." Biological specificity within ''Homo sapiens'' ''Homo sapiens'' has many characteristics that show the biological specificity in the form of behavior and morphological traits. Morphologically, humans have an enlarged cranial capacity and more gracile features in comparison to other hominins. The reduction of dentition is a feature that allows for the advantage of adaptability in diet and survival. As a species, humans are culture dependent and much of human survival relies on the culture and so ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Phyllastrephus
''Phyllastrephus'' is a songbird genus in the bulbul family Pycnonotidae. Most of the species in the genus are typical greenbuls, though two are brownbuls, and one is a leaflove. Taxonomy and systematics The genus ''Phyllastrephus'' was introduced by the English naturalist William John Swainson in 1832 with ''Le Jaboteur'' ( Levaillant), now the terrestrial brownbul, as the type species. The genus name combines the Ancient Greek ''phullon '' meaning "leaf" with ''strephō'' meaning "to toss" or "to turn". Species The genus contains the following 20 species: * Lowland tiny greenbul (''Phyllastrephus debilis'') * Montane tiny greenbul (''Phyllastrephus albigula'') * White-throated greenbul (''Phyllastrephus albigularis'') * Xavier's greenbul (''Phyllastrephus xavieri'') * Icterine greenbul (''Phyllastrephus icterinus'') * Terrestrial brownbul (''Phyllastrephus terrestris'') * Cameroon olive greenbul (''Phyllastrephus poensis'') * Northern brownbul (''Phyllastrephus strepi ...
