hispida complexes are compared in an attempt to account for the different modes of evolution observed in these closely related groups of Calycadenia. Lacking other plausible explanations, it is suggested that differential methods for limiting recombination of critical adaptive gene complexes might account...
Differential interference contrast microscopy (DIC): This type is also known as Nomarski microscopy and is a method used in optical microscopy illumination to augment the contrast in unstained, crystal clear specimens. This technique utilizes interferometery to access data on the optical path length o...
