Adaptation and adaptive radiation
2019A key outcome of evolution by natural selection is adaptation. Since the beginning of the age of genetics, evolutionary biologists have focused on the evolution of nuclear genes as the basis for adaptation. Changes to the mitochondrial genome were long viewed as the result of drift and unimportant to organism fitness.

Adaptation and constraint in a stickleback radiation
Journal of Evolutionary Biology, 2013AbstractThe evolution of threespine sticklebacks in freshwater lakes constitutes a well‐studied example of a phenotypic radiation that has produced numerous instances of parallel evolution, but the exact selective agents that drive these changes are not yet fully understood.

Online Adaptive Radiation Therapy
International Journal of Radiation Oncology*Biology*Physics, 2017The current paradigm of radiation therapy has the treatment planned on a snapshot dataset of the patient's anatomy taken at the time of simulation. Throughout the course of treatment, this snapshot may vary from initial simulation. Although there is the ability to image patients within the treatment room with technologies such as cone beam computed ...

Population Genomics of Adaptive Radiation
Molecular EcologyAdaptive radiations are rich laboratories for exploring, testing, and understanding key theories in evolution and ecology because they offer spectacular displays of speciation and ecological adaptation. Particular challenges to the study of adaptive radiation include high levels of species richness, rapid speciation, and gene flow between species. Over

Adaptive radiation is the simultaneous diversification of a lineage into numerous sublineages and specializations (Simpson, 1953a). All of the species of a radiation constitute a monophyletic group, and they often share some innovative trait or set of traits (sometimes called a key innovation—Liem, 1973) that is thought to have allowed the lineage to ...

Citation analysis and adaptive radiation
Scientometrics, 1987Bibliometrics does not allow prediction of the duration of research fronts. Utilizing an analogy with the concept of adaptive radiation, this heuristic article suggests a technique which may permit a measure of predictability to bibliometrics.

Neotropics as a Cradle for Adaptive Radiations
Cold Spring Harbor Perspectives in BiologyNeotropical ecosystems are renowned for numerous examples of adaptive radiation in both plants and animals resulting in high levels of biodiversity and endemism. However, we still lack a comprehensive review of the abiotic and biotic factors that contribute to these adaptive radiations.

The Adaptive Radiation of Proprioceptors
1978The term “proprioception”, coined by Sherrington (1906) has become an accepted and frequently used word in the vocabulary of sensory physiologists. However its popular use has been accompanied by a loss of precision in its meaning. It is, therefore not inappropriate in 1977 to look again at the definition of proprioception as it was originally ...
