Population decline in the federally endangered June sucker (Chasmistes liorus), a lakesucker unique to Utah Lake, Utah, has been attributed in part to hybridization with the more widespread Utah sucker (Catostomus ardens). As a group, suckers in Utah Lake exhibit considerable external morphological variation. Meristic and morphological ambiguities, presumably the result of hybridization, create a continuum of intermediate forms between Chasmistes and Catostomus extremes and prevent definitive… 
Multivariate heritability of shape in June sucker (Chasmistes liorus) and Utah sucker (Catostomus ardens): shape as a functional trait for discriminating closely related species
TLDR
Evaluating the distribution of shape phenotypes among purebreds of each species and their hybrids and determined the heritability of shape and ecological performance between June sucker and its sister species Utah sucker found little evidence for differential selection between species that would maintain shape variation.
Complete mitochondrial genomes of June sucker and Utah sucker (Chasmistes liorus and Catostomus ardens)
TLDR
The data suggest that Chasmistes liorus is sister to Catostomus ardens, and additional samples from multiple localities and/or cohorts of these species will allow us to better resolve the complicated phylogenetic relationships between these species.
Introgressive Hybridization and the Evolution of Lake-Adapted Catostomid Fishes
TLDR
Patterns of gene flow among four species of catostomid fishes from the Klamath and Rogue rivers are examined using molecular and morphological traits and it is concluded that observed patterns are most easily explained by introgressive hybridization among Klamaths BasinCatostomids.
Building a Better June Sucker: Characterization of Mouth Shape in the Captive Brood Stock
TLDR
To determine the utility of current captive brood lots to produce June sucker phenotypes, shape of the lip lobes on the lower jaw of each brood lot was characterized using geometric morphometrics and selection on lower lip shape in captive broodLots may be required to recreate June suckerphenotypes from captive brood stock.
Lake Suckers in the Western USA: History, Ecology, and Birliography of an Endangered Genus
TLDR
This special feature of the Western North American Naturalist is dedicated to lake sucker ecology and natural history and provides a central venue for publication of several papers presented in the symposium.
Ecomorphological and Genetic Investigations into the Utah Lake, UT Sucker Complex with Comparisons to the Jackson Lake, WY Sucker Complex
TLDR
A comparison of MORPHOLOGY with GENETIC STRUCTURE and STABLE ISOTOPIC SIGNATURES in the JACKSON LAKE SUCKER COMPLEX finds that the former is more stable than the latter.
Considerations for the Propagation and Conservation of Endangered Lake Suckers of the Western United States
Abstract Decades of persistent natural and anthropogenic threats coupled with competing water needs have compromised numerous species of freshwater fishes, many of which are now artificially
Historical biogeography reveals new independent evolutionary lineages in the Pantosteus plebeius-nebuliferus species-group (Actinopterygii: Catostomidae)
TLDR
The evolutionary history of the Pantosteus plebeius-nebuliferus species-group is characterized by vicariant post-dispersal processes linked to geological changes in the Sierra Madre Occidental and central Northern Mexico since the Pliocene, congruent with biogeographic patterns described for other co-distributed fish species.
Redescription of the Tyee Sucker, Catostomus tsiltcoosensis (Catostomidae)
TLDR
Evidence suggests that introgression and lateral transfer of mitochondria explains the cytochrome b pattern in C. tsiltcoosensis, except that the Coquille River population appears not to have been included in recent transfers, and speculation that lateral transfer might also be responsible for the pattern.
Residence time and drift patterns of larval June sucker Chasmistes liorus in the lower Provo River as determined by otolith microstructure.
TLDR
Patterns in catch and age distribution of larval C. liorus in the lower Provo River suggest that recruitment failure occurs during the larval drift period in years with insufficient discharge to transport larvae into the lake.

TLDR
There is insufficient evidence to deem these taxa hybrids, or the webug sucker, extinct, according to a comparative examination of the published descriptions of the internal and external anatomy of these two species.
SPECIES FLOCK IN THE NORTH AMERICAN GREAT LAKES: MOLECULAR ECOLOGY OF LAKE NIPIGON CISCOES (TELEOSTEI: COREGONIDAE: COREGONUS)
Studies on north temperate fish species indicate that new habitat availability following the last ice sheet retreat has promoted ecological speciation in postglacial lakes. Extensive ecophenotypic
Patterns of Intra- and Interspecies Genetic Diversity in Klamath River Basin Suckers
TLDR
The primary aims of this study were to measure interspecific and intraspecific genetic variation in Klamath River basin suckers by examining 15 microsatellite loci and hierarchical analysis of population subdivision based on groups generated from micros satellite genetic distance (R ST) data was performed.
DIVERGENCE WITH GENE FLOW IN THE ROCK‐DWELLING CICHLIDS OF LAKE MALAWI
TLDR
The effect of recent lake‐level fluctuations on patterns of allelic diversity in the genus Metriaclima is determined, to describe the patterns of population structure within this genus, and to identify barriers to migration.
Morphology and taxonomy of Klamath Basin suckers (Catostomidae)
TLDR
The possibility that a large-headed, thin-lipped species has become extinct in Upper Klamath Lake is discussed and it is suggested that the form could represent an ecophenotype of Ch.
Lake level fluctuations synchronize genetic divergences of cichlid fishes in African lakes.
TLDR
The data suggest that the same climatic phenomenon synchronized the onset of genetic divergence of lineages in all three species flocks, such that their most recent evolutionary history seems to be linked to the same external modulators of adaptive radiation.
Contrasting patterns of mitochondrial DNA and microsatellite introgressive hybridization between lineages of lake whitefish (Coregonus clupeaformis); relevance for speciation
TLDR
Assessment of mitochondrial DNA and microsatellite loci among lake whitefish populations indicated that environmental differences may be as important as the historical contingency of secondary contact in explaining the persistence of sympatric ecotypes and the differential pattern of introgressive hybridization among lakes.
Sympatric speciation in Nicaraguan crater lake cichlid fish
TLDR
A convincing case of sympatric speciation is presented in the Midas cichlid species complex (Amphilophus sp.) in a young and small volcanic crater lake in Nicaragua and it is found that the two species in Lake Apoyo are reproductively isolated and eco-morphologically distinct.
Ecological Speciation in Postglacial Fishes
TLDR
It is argued that knowledge of ecological environments is essential to understanding the origin of species in adaptive radiation, and perhaps more generally to complement (and perhaps transform) traditional genetic approaches to speciation.
