Masai Ostrich
The Masai ostrich (''Struthio camelus massaicus''), also known as the East African ostrich is a red-necked subspecies variety of the common ostrich and is endemic to East Africa. It is one of the largest birds in the world, second only to its sister subspecies ''Struthio camelus camelus''. Today it is hunted and farmed for eggs, meat, and feathers. Taxonomy Subspecies The Masai ostrich is one of the four extent subspecies of ostrich currently inhabiting Africa, including the nominative ostrich ('' S. c. camelus'') found across northern Africa, the South African ostrich ('' S. c. australis''), and the Somali ostrich ('' S. c. molybdyphanes''). It is considered one of the two red-necked forms of ostrich, along with ''S. c. camelus'', as opposed to the two blue-necked forms (''S. c. australis'' and ''S. c. molybdyphanes''). Comparative restriction-enzyme analysis of mitochondrial DNA (mtDNA) found the Masai ostrich, though genetically distinct, is most closely related to ''S. ...

Thermoregulation
Thermoregulation is the ability of an organism to keep its body temperature within certain boundaries, even when the surrounding temperature is very different. A thermoconforming organism, by contrast, simply adopts the surrounding temperature as its own body temperature, thus avoiding the need for internal thermoregulation. The internal thermoregulation process is one aspect of homeostasis: a state of dynamic stability in an organism's internal conditions, maintained far from thermal equilibrium with its environment (the study of such processes in zoology has been called physiological ecology). If the body is unable to maintain a normal temperature and it increases significantly above normal, a condition known as hyperthermia occurs. Humans may also experience lethal hyperthermia when the wet bulb temperature is sustained above for six hours. The opposite condition, when body temperature decreases below normal levels, is known as hypothermia. It results when the homeostatic ...

Jackal
Jackals are medium-sized canids native to Africa and Eurasia. While the word "jackal" has historically been used for many canines of the subtribe canina, in modern use it most commonly refers to three species: the closely related black-backed jackal (''Lupulella mesomelas'') and side-striped jackal (''Lupulella adusta'') of sub-Saharan-Africa, and the golden jackal (''Canis aureus'') of south-central Europe and Asia. The African golden wolf (''Canis lupaster'') was also formerly considered as a jackal. While they do not form a monophyletic clade, all jackals are opportunistic omnivores, predators of small to medium-sized animals and proficient scavengers. Their long legs and curved canine teeth are adapted for hunting small mammals, birds, and reptiles, and their large feet and fused leg bones give them a physique well-suited for long-distance running, capable of maintaining speeds of for extended periods of time. Jackals are crepuscular, most active at dawn and dusk. Th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ostrich Eggs In A Nest At An Ostrich Farm, South Pasadena, Ca
Ostriches are large flightless birds of the genus ''Struthio'' in the order Struthioniformes, part of the infra-class Palaeognathae, a diverse group of flightless birds also known as ratites that includes the emus, rheas, and kiwis. There are two living species of ostrich: the common ostrich, native to large areas of sub-Saharan Africa and the Somali ostrich, native to the Horn of Africa. The common ostrich was also historically native to the Arabian Peninsula, and ostriches were present across Asia as far east as Mongolia during the Late Pleistocene and possibly into the Holocene. They lay the largest eggs of any living land animal. With the ability to run at 70 km/h (43.5 mph), they are the fastest birds on land. They are farmed worldwide, particularly for their feathers as they are used as decoration and feather dusters. Their skin is also used for leather products. They are the heaviest living birds.

Crèche (zoology)
The crèche (from French) in zoology refers to care of offspring in a group or colony. Many species such as common eider, lions, and penguins form crèche and exhibit group behaviours. Crèches can serve different functions and purposes depending on the species and the environment. For example, some crèches may aid in defence while other crèches may aid in feeding and protection from harsh weather conditions. This form of group living has evolved over time to become advantageous to the species. Studies have shown that by participating in group living, species will increase their inclusive fitness since their young will be in a better condition to reproduce and carry on the line of descendants in the species. Crèche behaviour in eiders, ''Somateria mollissima'' In the Common eider population, after giving birth to their eggs, the mother will incubate them until they hatch. The mothers will hear a signal from the juvenile's which will cause her to move away and open the nest ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Savanna
A savanna or savannah is a mixed woodland- grassland (i.e. grassy woodland) ecosystem characterised by the trees being sufficiently widely spaced so that the canopy does not close. The open canopy allows sufficient light to reach the ground to support an unbroken herbaceous layer consisting primarily of grasses. According to '' Britannica'', there exists four savanna forms; ''savanna woodland'' where trees and shrubs form a light canopy, ''tree savanna'' with scattered trees and shrubs, ''shrub savanna'' with distributed shrubs, and ''grass savanna'' where trees and shrubs are mostly nonexistent.Smith, Jeremy M.B.. "savanna". Encyclopedia Britannica, 5 Sep. 2016, https://www.britannica.com/science/savanna/Environment. Accessed 17 September 2022. Savannas maintain an open canopy despite a high tree density. It is often believed that savannas feature widely spaced, scattered trees. However, in many savannas, tree densities are higher and trees are more regularly spaced than in f ...

Uganda
}), is a landlocked country in East Africa. The country is bordered to the east by Kenya, to the north by South Sudan, to the west by the Democratic Republic of the Congo, to the south-west by Rwanda, and to the south by Tanzania. The southern part of the country includes a substantial portion of Lake Victoria, shared with Kenya and Tanzania. Uganda is in the African Great Lakes region. Uganda also lies within the Nile basin and has a varied but generally a modified equatorial climate. It has a population of around 49 million, of which 8.5 million live in the capital and largest city of Kampala. Uganda is named after the Buganda kingdom, which encompasses a large portion of the south of the country, including the capital Kampala and whose language Luganda is widely spoken throughout the country. From 1894, the area was ruled as a protectorate by the United Kingdom, which established administrative law across the territory. Uganda gained independence from the UK on 9 ...

Soda Lake
A soda lake or alkaline lake is a lake on the strongly alkaline side of neutrality, typically with a pH value between 9 and 12. They are characterized by high concentrations of carbonate salts, typically sodium carbonate (and related salt complexes), giving rise to their alkalinity. In addition, many soda lakes also contain high concentrations of sodium chloride and other dissolved salts, making them saline or hypersaline lakes as well. High pH and salinity often coincide, because of how soda lakes develop. The resulting hypersaline and highly alkalic soda lakes are considered some of the most extreme aquatic environments on Earth.Grant, W. D. (2006). ''Alkaline environments and biodiversity.'' in ''Extremophiles'', 2006, UNESCO / Eolss Publishers, Oxford, UK In spite of their apparent inhospitability, soda lakes are often highly productive ecosystems, compared to their (pH-neutral) freshwater counterparts.
