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

Abstract What is adaptive radiation? A working definition and the means to apply it are crucial to successful study of the process. Modern usage derives from Simpson (1953, p. 223): ‘adaptive radiation strictly speaking refers to more or less simultaneous divergence of numerous lines from much the same adaptive type into different, also ...

Environmental Adaptations: Radiation Tolerance
2018Several studies in different species have documented that tardigrades are among the most radiation-tolerant animals on Earth, surviving doses of ionizing radiation on the order of kGy. Both low-LET and high-LET radiation have been used with no apparent differences in the tolerance of the animals.

Ibis, 1969
Summary.Because of its homogeneity, both taxonomical and ecological, the sea‐bird family Alcidae constitutes an appropriate group for the study of adaptive radiation. This radiation involves mainly the acquisition of specialized feeding habits and the consequent specialization of the various species of the family at different trophic levels.The ...

Adaptive radiation and insects
2010The fundamental aspect of principle of divergence has emerged in different spheres of evolutionary biology as propounded by Charles Darwin. Adaptive radiation is an aspect of evolutionary biology encompassing microevolution and macroevolution, explaining the principles of divergence, taking into account the theories of natural selection and struggle ...
