We determined the number and distribution of rRNA genes among individuals of eight pitch pine populations representing a small ecosystem. While these populations show little or no variation for allozymes and also experience high gene flow, they exhibit large amounts of morphological diversity, apparently caused by environmental stress. Nine to ten… CONTINUE READING
