Botha's Lark
Botha's lark (''Spizocorys fringillaris'') is a species of lark in the family Alaudidae. It is endemic to South Africa. Its natural habitats are subtropical or tropical high-altitude grassland and pastureland. It is threatened by habitat loss. Taxonomy and systematics Botha's lark was originally placed in the genus '' Alauda''. Formerly, some authorities have classified it within either the genus ''Calandrella ''Calandrella'' is a genus of larks in the family Alaudidae.

Carl Jakob Sundevall
Carl Jakob Sundevall (22 October 1801, Högestad – 2 February 1875) was a Swedish zoologist. Sundevall studied at Lund University, where he became a Ph.D. in 1823. After traveling to East Asia, he studied medicine, graduating as Doctor of Medicine in 1830. He was employed at the Swedish Museum of Natural History, Stockholm from 1833, and was professor and keeper of the vertebrate section from 1839 to 1871. He wrote ''Svenska Foglarna'' (1856–87) which described 238 species of birds observed in Sweden. He classified a number of birds collected in southern Africa by Johan August Wahlberg. In 1835, he developed a phylogeny for the birds based on the muscles of the hip and leg that contributed to later work by Thomas Huxley. He then went on to examine the arrangement of the deep plantar tendons in the bird's foot. This latter information is still used by avian taxonomists. Sundevall was also an entomologist and arachnologist, for which (for the latter field) in 1833 he publish ...

Lark
Larks are passerine birds of the family Alaudidae. Larks have a cosmopolitan distribution with the largest number of species occurring in Africa. Only a single species, the horned lark, occurs in North America, and only Horsfield's bush lark occurs in Australia. Habitats vary widely, but many species live in dry regions. When the word "lark" is used without specification, it often refers to the Eurasian skylark ''(Alauda arvensis)''. Taxonomy and systematics The family Alaudidae was introduced in 1825 by the Irish zoologist Nicholas Aylward Vigors as a subfamily Alaudina of the finch family Fringillidae. Larks are a well-defined family, partly because of the shape of their . They have multiple scutes on the hind side of their tarsi, rather than the single plate found in most songbirds. They also lack a pessulus, the bony central structure in the syrinx of songbirds. They were long placed at or near the beginning of the songbirds or oscines (now often called Passeri), just afte ...

Endemism
Endemism is the state of a species being found in a single defined geographic location, such as an island, state, nation, country or other defined zone; organisms that are indigenous to a place are not endemic to it if they are also found elsewhere. For example, the Cape sugarbird is found exclusively in southwestern South Africa and is therefore said to be ''endemic'' to that particular part of the world. An endemic species can be also be referred to as an ''endemism'' or in scientific literature as an ''endemite''. For example '' Cytisus aeolicus'' is an endemite of the Italian flora. '' Adzharia renschi'' was once believed to be an endemite of the Caucasus, but it was later discovered to be a non-indigenous species from South America belonging to a different genus. The extreme opposite of an endemic species is one with a cosmopolitan distribution, having a global or widespread range. A rare alternative term for a species that is endemic is "precinctive", which applies to ...

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 ...

Grassland
A grassland is an area where the vegetation is dominated by grasses (Poaceae). However, sedge (Cyperaceae) and rush (Juncaceae) can also be found along with variable proportions of legumes, like clover, and other herbs. Grasslands occur naturally on all continents except Antarctica and are found in most ecoregions of the Earth. Furthermore, grasslands are one of the largest biomes on earth and dominate the landscape worldwide. There are different types of grasslands: natural grasslands, semi-natural grasslands, and agricultural grasslands. They cover 31–69% of the Earth's land area. Definitions Included among the variety of definitions for grasslands are: * "...any plant community, including harvested forages, in which grasses and/or legumes make up the dominant vegetation." * "...terrestrial ecosystems dominated by herbaceous and shrub vegetation, and maintained by fire, grazing, drought and/or freezing temperatures." (Pilot Assessment of Global Ecosystems, 2000) * "A ...

Pasture
Pasture (from the Latin ''pastus'', past participle of ''pascere'', "to feed") is land used for grazing. Pasture lands in the narrow sense are enclosed tracts of farmland, grazed by domesticated livestock, such as horses, cattle, sheep, or swine. The vegetation of tended pasture, forage, consists mainly of grasses, with an interspersion of legumes and other forbs (non-grass herbaceous plants). Pasture is typically grazed throughout the summer, in contrast to meadow which is ungrazed or used for grazing only after being mown to make hay for animal fodder. Pasture in a wider sense additionally includes rangelands, other unenclosed pastoral systems, and land types used by wild animals for grazing or browsing. Pasture lands in the narrow sense are distinguished from rangelands by being managed through more intensive agricultural practices of seeding, irrigation, and the use of fertilizers, while rangelands grow primarily native vegetation, managed with extensive practices like co ...

Habitat Loss
Habitat destruction (also termed habitat loss and habitat reduction) is the process by which a natural habitat becomes incapable of supporting its native species. The organisms that previously inhabited the site are displaced or dead, thereby reducing biodiversity and species abundance. Habitat destruction is the leading cause of biodiversity loss. Fragmentation and loss of habitat have become one of the most important topics of research in ecology as they are major threats to the survival of endangered species. Activities such as harvesting natural resources, industrial production and urbanization are human contributions to habitat destruction. Pressure from agriculture is the principal human cause. Some others include mining, logging, trawling, and urban sprawl. Habitat destruction is currently considered the primary cause of species extinction worldwide. Environmental factors can contribute to habitat destruction more indirectly. Geological processes, climate change, introdu ...

Alauda
''Alauda'' is a genus of larks found across much of Europe, Asia and in the mountains of north Africa, and one of the species (the Raso lark) endemic to the islet of Raso in the Cape Verde Islands. Further, at least two additional species are known from the fossil record. The current genus name is from Latin ''alauda'', "lark". Pliny the Elder thought the word was originally of Celtic origin. Taxonomy and systematics The genus ''Alauda'' was introduced by the Swedish naturalist Carl Linnaeus in 1758 in the tenth edition of his ''Systema Naturae''. The type species was subsequently designated as the Eurasian skylark. The genus ''Alauda'' has four extant and at least two extinct species. Formerly, many other species have also been considered to belong to the genus. Extant species The genus contains four species: Extinct species * †''Alauda xerarvensis'' (late Pliocene of Varshets, Bulgaria) * †''Alauda tivadari'' (late Miocene of Polgardi, Hungary) Former species Previ ...

Calandrella
''Calandrella'' is a genus of larks in the family Alaudidae. Taxonomy and systematics The genus ''Calandrella'' was established by the German naturalist Johann Jakob Kaup in 1829 with the greater short-toed lark as the type species. The genus name is a diminutive of Ancient Greek ''kalandros'', the calandra lark. Four of the species in the genus use the shortened name of short-toed lark as an alternate name. Extant species Six species are recognized in the genus: Extinct species At least one fossil species is included in this genus: * †''Calandrella gali'' (late Miocene of Polgardi, Hungary) Former species Some authorities have classified the following species as belonging to the genus ''Calandrella'': * Buckley's lark (as ''Calandrella buckleyi'') * Obbia lark (as ''Calandrella obbiensis'') * Sclater's lark (as ''Calandrella sclateri'') * Stark's lark (as ''Calandrella starki'') * Masked lark (as ''Calandrella personata'') * Botha's lark (as ''Calandrella fringillaris'') * ...
