stasipatric, a. Biol.|stæsɪˈpætrɪk|
[f. Gr. στάσις stasis + πάτρα fatherland (f. πατήρ father) + -ic.]
Applied to a form of speciation in which new taxa are considered to arise within the geographical range of the parent species, each part of which comes to be occupied by one of the new taxa. Hence stasiˈpatrically adv.
1967M. J. D. White et al. in Austral. Jrnl. Zool. XV. 298 If a term, equivalent to allopatric and sympatric, is needed to describe the process of direct conversion of an essentially continuous population into a number of contiguous taxa (races, semispecies, or species) by the spread of chromosomal rearrangements around which isolating mechanisms develop, one might perhaps choose the adjective stasipatric, which is intended to indicate the essentially unchanging geographic range of the superspecies. 1968Science 8 Mar. 1069/1 In the case of a chromosomal rearrangement which first establishes itself near the edge of a species distribution, one can imagine it spreading both inwards through the range of the species (stasipatrically) and outwards into previously unoccupied territory (allopatrically). 1973L. S. Dillon Evolution x. 138/2 The stasipatric model is not designed to displace the established ones but to supplement them. |
