COSEWIC assessment and update status report on the small-mouthed salamander Ambystoma texanum in Canada
In this update of the 1991 status report for the Small-mouthed Salamander, we bring together all available data that relate to the distribution of Ambystoma texanum on Pelee Island: the only Canadian locality for this species. We include locality information for Ambystoma texanum, A. laterale and diploid, triploid and tetraploid genomic hybrids that also exist on the island because: (1) the identification of A. texanum, and distinguishing that species from the genomic hybrids is confusing; and (2) both A. texanum and A. laterale males are used as sperm donors for the persistence of genomic hybrid combinations. Although this update only considers the status of "pure" diploid A. texanum, the presence of rare A. texanum males can be estimated through an examination of the more common genomic hybrids.
