The endangered Sonoran topminnow P. occidentalis has steadily declined in distribution and abundance in the past several decades, and currently survives in the United States only in several isolated localities in southern Arizona. This reduction is correlated with, and primarily attributed to, habitat destruction, and introduction and establishment of mosquitofish Gambusia affinis and other exotic fishes. Topminnows have characteristically been reduced in number or replaced within a year or two of introduction of non-native fishes. Other native fishes have experienced similar declines after introduction of exotics, and much of the endemic western ichthyofauna may be vulnerable to extirpation in this manner. Predation by introduced fishes on natives appears to be a likely mechanism of replacement

Hendrickson, Dean A., and W.L. Minckley. “Ciénegas-vanishing climax communities of the American Southwest.” Desert Plants 6 (3): 131–175. Publisher’s Version
The term cienega is here applied to mid-elevation (1,000-2,000 m) wetlands characterized by permanently saturated, highly organic, reducing soils. A depauperate flora dominated by low sedges highly adapted to such soils characterizes these habitats. Progression to cienegais dependent on a complex association of factors most likely found in headwater areas. Once achieved, the community appears stable and persistent since paleoecological data indicate long periods of cienegaconditions, with infrequent cycles of incision. We hypothesize the cienega to be an aquatic climax community. Cienegas and other marshland habitats have decreased greatly in Arizona in the past century. Cultural impacts have been diverse and not well documented. While factors such as grazing and streambed modifications contributed to their destruction, the role of climate must also be considered. Cienega conditions could be restored at historic sites by provision of constant water supply and amelioration of catastrophic flooding events.

Hendrickson, Dean A. “Congruence of bolitoglossine biogeography and phylogeny with geologic history: Paleotransport on displaced suspect terranes?.” Cladistics 3 (2): 113–129. Publisher’s Version
A vicariance hypothesis of New World biogeography involving transport of living biota on fragments of an ancestral landmass to present positions ranging from southern Alaska to northern South America is developed. Geological, as well as biogeographical, ecological, and systematic data from plethodontid salamanders provide correlative support for the model. Other groups appear to have similar biogeographic histories and, along with further geological data, could provide means of corroboration of this hypothesis. Active biotic dispersal between the American continents before Pliocene closure of the Panamanian isthmus may have been less prevalent than previously believed, and tectonic transport may have dispersed many organisms. If corroborated, geologists may be provided a new method of analyzing relationships among “suspect terranes” using phylogenetic analyses of living biota, and biologists may be required to reassess previous concepts of New World historical biogeography.

Hendrickson, Dean A. “Geographic variation in morphology of Agosia chrysogaster, a Sonoran desert cyprinid fish.” Tempe, Arizona: Arizona State University. Publisher’s Version
Morphometric analyses of Agosia chrysogaster (Girard) indicated a northern morph native to Bill Williams, Gila, Sonoyta and de la Concepcion basins of Arizona, New Mexico and Sonora, and a southern form from Willcox Playa of Arizona and Rios Sonora, Yaqui, Mayo, Fuerte and Sinaloa of Sonora and Sinaloa, Mexico. The latter is smaller, and less sexually dimorphic, but has longer pre and postdorsal body lengths. Populations in the geographically intermediate Rios Sonoyta and Sonora are morphologically intermediate. Males differ more between morphs than do females. Meristic characters show considerable overlap between morphs, but the northern form has higher mean lateral line scale counts. Highly tuberculate nuptial males, characteristic of the northern morph, were not found in the south, nor were “spawning” pits characteristic of breeding activities of the former. Morphs differ on a multivariate axis on which temporal variation at single localities is also reflected. Distances among some intra locality samples on this axis were greater than least inter morph distances. Measures of morphological dissimilarity were weakly correlated with inter sample differences in elevation, latitude, and longitude, but more highly correlated with an index of hydrologic isolation among localities. Differentiation among basins thus appears to reflect hydrographic isolation, rather than ecological conditions. Electrophoretic data on A. chrysogaster produced relationships patterns largely incongruent with results of the morphological analyses, and with unexpected geographic area relationships.

Subadult and adult fishes from the Gila River drainage in New Mexico and Arizona were tagged, released, and recaptured from April 1983 through May 1985. Numbers of tagged and recaptured fish were dominated by desert mountain sucker, Pantosteus clarki, and Sonora sucker, Catostomus insignis. Fishes were presumed to be sedentary as only two of 53 recaptures were made outside of original release sites. The relatively large habitats and comparatively cool thermal regime of the study area are believed to be the primary reasons for the apparent lack of movement. Growth rates of recaptured fishes were low and indicated that desert mountain and Sonora suckers grow slowly after reaching adult size.
