Editorial and introduction: The species concept in fish biology

Editorial and introduction: The species concept in fish biology 1968) dealt with hybridization between two suckers, into sympatry they would fuse. Ecophenotypes would Catostomus commersonii and C. macrocheilus.They not qualify as subspecies. Example: Esox americanus occupied separate glacial refugia and appear to hybrid- americanus and E.a. vermiculatus. Although many ize in all sympatric locations, yet maintain their iden- workers doubt the value of this category (e.g. see tity – I was a fan of the basic species concept expressed Rainer Froese’s article herein), I feel it useful in stud- in Mayr (1942) and later works and the sucker study ies of biodiversity or conservation where we wish to convinced me that species were objective units whose draw attention in formal taxonomy to cases where integrity could not be destroyed even in the face of there has been some recognizable divergence, as noted interbreeding with other species under natural sym- above, within a species. Only a minority of species patric conditions (i.e. species were, in part, irreversible may warrant the recognition of subspecies. Lower discontinuities, unlike lower units of classification). I levels of intraspecific diversity may be recognized have since benefited from recent papers such as those whether or not subspecies are described. of Wiley and Mayden (1985), Schwartz http://www.deepdyve.com/assets/images/DeepDyve-Logo-lg.png Reviews in Fish Biology and Fisheries Springer Journals
