Abstract Introgressive hybridization has important management and evolutionary consequences in regard to the maintenance of the integrity of gene pools and the acquisition of new alleles by means other than mutation. Among North American cypriniform fishes, hybridization often occurs between historically allopatric forms placed into sympatry via human activities and between sympatric forms inhabiting a modified environment. In the Colorado River system, several native catostomids are known to hybridize, including ...

Tissue extracts of skeletal muscle, heart, eye, brain, liver, kidney, gill and stomach were electrophoretically examined for glucose dehydrogenase (EC 1.1.1.47) activity in 21 species of marine teleost fishes. Glucose dehydrogenase expression was detected only in liver extracts. Considerable interordinal variation was found in levels of enzymatic activity. Available data support the hypothesis that glucose dehydrogenase provides NADPH for the mixed-function oxidase system in teleosts.

1. Karyotypically tetraploid fishes of the catostomid tribe Moxostomatini were electrophoretically examined to ascertain in the genetic control of 14 enzyme systems (21 loci in dipoid Cypriniformes). 2. The Moxostomatini have become functionally diploid at 50% or more of their loci since the original polyploidization event in the catosomid line. 3. The subgenera Megapharynx and Moxostoma s.s. (genus Moxostoma) are recognized as comprising a single lineage on the basis of synapomorphic diploidization at the G-3-pdh-A locus. 4. Thoburnia s.l. is allied with the genus Hypentelium on the basis of synapomorphic diploidization at the M-Aat-A locus supporting separate generic status for Thorburnia s.l.

ABSTRACT Phylogenetic relationships among the western North American cyprinids Mylopharodon conocephalus and the four species of Ptychocheilus-P. grandis, P. lucius, P. oregonensis, and P. umpquae-were estimated from the perspective of an outgroup species, Hesperoleucus symmetricus. Canonical variate analysis (CVA) of 46 morphometric measures yielded scores that had group bivariate prediction ellipses with minimal overlap among species (95% prediction interval). These measures also indicated large phenetic differences between P. lucius and M. conocephalus, and other ingroup taxa. Ptychocheilus umpquae from the Umpqua and Siuslaw drainages was easily separable and may warrant recognition as separate taxa. Gap-coding of six counts and 35 measures yielded multistate characters that were then subjected to parsimony analysis. This analysis yielded a single tree with a consistency index of 0.868, with most of the homoplasy associated with P. lucius. The Wagner analysis supported the monophyly of the genus Ptychocheilus and the relationships within the genus of (oregonensis [umpquae (grandis, lucius)]) consistent with a north-to-south pattern of speciation. Given the ages of fossil taxa in the genus and their hypothesized relationships to extant members, the genus evolved prior to the Miocene. No taxonomic changes have been proposed for this group at this time, although additional study of the population currently recognized as P. umpquae inhabiting the Siuslaw drainage is warranted. A key to the species of Ptychocheilus has been provided.
