Adaptive radiation is not a strictly vertebrate phenomenon, and examples are also known from among plants. The most famous example of adaptive radiation in plants is quite possibly the Hawaiian silverswords , named for alpine desert-dwelling Argyroxiphium species with long, silvery leaves that live for up to 20 years before growing a single ...
The radiation adaptive response seems to be a main origin of the potential hormetic effect. The theoretical studies indicate that the adaptive response is responsible for the shape of dose-response curve and can transform the linear relationship (LNT) into the hormetic one. [25] [26]
A key innovation may allow a species to invade a new region or niche and thus be freed from competition, allowing subsequent speciation and radiation. A classic example of this is the fourth cusp of mammalian molars, the hypocone, which allowed early mammalian ancestors to effectively digest their generalised diet. The precursors to this, the ...
An evolutionary radiation is an increase in taxonomic diversity that is caused by elevated rates of speciation, [1] that may or may not be associated with an increase in morphological disparity. [2] A significantly large and diverse radiation within a relatively short geologic time scale (e.g. a period or epoch) is often referred to as an ...
Examples of divergence in nature are the adaptive radiation of the finches of the Galápagos, changes in mobbing behavior of the kittiwake, and the evolution of the modern-day dog from the wolf. The term can also be applied in molecular evolution , such as to proteins that derive from homologous genes.
Radiation is the evolutionary process of diversification of a single species into multiple forms. It includes the physiological and ecological diversity within a rapidly multiplying lineage. [ 8 ] There are many types of radiation including adaptive, concordant, and discordant radiation however escape and radiate coevolution does not always ...
Infrared or red radiation from a common household radiator or electric heater is an example of thermal radiation, as is the heat emitted by an operating incandescent light bulb. Thermal radiation is generated when energy from the movement of charged particles within atoms is converted to electromagnetic radiation.
Radiative transfer (also called radiation transport) is the physical phenomenon of energy transfer in the form of electromagnetic radiation. The propagation of radiation through a medium is affected by absorption, emission, and scattering processes. The equation of radiative transfer describes these interactions mathematically. Equations of ...
