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 ...
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 ...

This is a list of adaptive radiated marsupials by form; they are adaptively radiated marsupial species equivalent to the many niche-types of non-marsupial mammals. Many of the surviving species are from Australia. There are unique types, for example the extinct genus Nototherium, a 'rhinoceros-type'. [1]
Adaptive radiation is when many species emerge in a short time. Yes, allopatric speciation may have been the manner in which all the species emerged in the adaptive radiation. Still, this does not make the radiation a form of speciation. Radiation is a form of a (large) group of speciations. --Ettrig 17:40, 17 October 2010 (UTC)
The second term describes absorption of radiation by the molecules in a short segment of the radiation's path (ds) and the first term describes emission by those same molecules. In a non-homogeneous medium, these parameters can vary with altitude and location along the path, formally making these terms n ( s ) , σ λ ( s ) , T ( s ) , and I λ ...

For example, Albinaria land snails on islands in the Mediterranean [1] and Batrachoseps salamanders from California [2] each include relatively dispersal-limited, and closely related, ecologically similar species often have minimal range overlap, a pattern consistent with allopatric, nonecological speciation.
