• dispersal
  • The population structure may be a result of founder events (non-random colonization), selection for spawning time (variable environments leading to isolation-bytime) or selection against dispersal (isolation-inspace). (uio.no)
  • Evidence
  • Evidence for reproductive isolate selection in Mediterranean orchids: karyotype differences compensate for the lack of pollinator specificity. (springer.com)
  • hybrid sterility
  • This is not surprising, given the ease of quantifying either sexual isolation or hybrid sterility as compared with tests for gametic interactions. (pnas.org)
  • selection
  • Reproductive isolation on the continental slope may have occurred as a result of selection exerted by gradients of depth-correlated physical factors, such as pressure and temperature. (nerc.ac.uk)
