The gemsbok (Oryx gazella), or South African oryx, is a large antelope in the genus Oryx. It is endemic to the dry and barren regions of Botswana , Namibia , South Africa and (parts of) Zimbabwe , mainly inhabiting the Kalahari and Namib Deserts , areas in which it is supremely adapted for survival.
Tylosema esculentum, with common names gemsbok bean and marama bean or morama bean, [2] is a long-lived perennial legume native to arid areas of southern Africa. Stems grow at least 3 metres (9.8 ft), in a prostrate or trailing form, with forked tendrils that facilitate climbing .
Prior to The Origin of Species, there was little appreciation or understanding of the dynamic and reciprocal relations between organisms, their adaptations, and the environment. [231] An exception is the 1789 publication Natural History of Selborne by Gilbert White (1720–1793), considered by some to be one of the earliest texts on ecology ...
In ecology, resilience is the capacity of an ecosystem to respond to a perturbation or disturbance by resisting damage and subsequently recovering. Such perturbations and disturbances can include stochastic events such as fires, flooding, windstorms, insect population explosions, and human activities such as deforestation, fracking of the ground for oil extraction, pesticide sprayed in soil ...
This kills off marine life or forces it to leave the area, removing life from the area and giving it the name dead zone. Hypoxic zones or dead zones can occur naturally, but nutrient pollution from human activity has turned this natural process into an environmental problem. [29] There are five main sources of nutrient pollution.
It is a simple relationship between a host (the forest), an agent (the beetle) and the environment (the weather and temperature). [92] However, as climate change causes mountain areas to become warmer and drier, pine beetles have more power to infest and destroy the forest ecosystems, such as the whitebark pine forests of the Rocky Mountains. [92]
Hanlon described the current legal environment as a “real sort of turf war, if you will, between the federal government and the states.” “The FAA is in charge of assuring the safety of the ...
The bushmen of the Kalahari eat the Gemsbok Cucumber after it has been roasted in a fire for a couple of hours. This cooking renders the "burning" chemicals harmless; even if the cooked pulp is still slightly bitter, the Bushman seem to relish eating them, sucking out the contents and either spitting out or chewing up the plentiful seeds.
