We examined intra‐specific phylogenetic relationships in leatherside chub, Gila copei. The complete mitochondrial (mt) cytochrome b gene (1140 bp) was sequenced for 30 individuals from 10 populations that span the geographical distribution of this species. Traditional phylogenetic analyses revealed two deeply divergent and evolutionarily distinct mtDNA clades that are geographically separated in northern and southern drainage basins. Inter‐population sequence variation between clades ranged…

Range-wide comparisons of northern leatherside chub populations reveal historical and contemporary patterns of genetic variation
TLDR
The results suggest that populations of leatherside chub were historically more widely inter-connected and have recently been isolated, likely through a combination of natural and anthropogenic habitat fragmentation.
Neglected taxonomy of rare desert fishes: congruent evidence for two species of leatherside chub.
TLDR
The two clades of leatherside chub are elevated to distinct species status (Lepidomeda copei in the north andL. aliciae in the south), and it is argued that each warrants independent conservation and recovery action.
Patterns of Molecular Diversity in Naturally Occurring and Refugial Populations of the Least Chub
TLDR
It is found that a large proportion of the diversity in this species was attributable to population structuring, and it is suggested that surveys to discover additional populations be a high management priority.
EVOLUTIONARY HISTORY OF THE NORTHERN LEOPARD FROG: RECONSTRUCTION OF PHYLOGENY, PHYLOGEOGRAPHY, AND HISTORICAL CHANGES IN POPULATION DEMOGRAPHY FROM MITOCHONDRIAL DNA
TLDR
A detailed history of how a widespread terrestrial vertebrate responded to episodic Pleistocene glacial events in North America is provided and illustrates how complementary methods of data analysis can be used to disentangle recent and ancient effects on the genetic structure of a species.
Natural history and evolution of a color polymorphism in Rana pipiens, the northern leopard frog
TLDR
This research helps to elucidate how biogeographic and microevolutionary forces influence a wide-spread North American species, R. pipiens, and exemplifies the importance of investigating for evidence of selective maintenance before studies attempt to measure the selective mechanisms maintaining a polymorphism.
Evolutionary Relationships of the Plagopterins (Teleostei: Cyprinidae) from Cytochrome b Sequences
Abstract Sequences of cytochrome b (cytb) were used to examine composition and phylogenetic relationships of cyprinid fishes of the tribe Plagopterini, endemic to the Great Basin and Lower Colorado…

Small Fish in a Large Landscape: Diversification of Rhinichthys osculus (Cyprinidae) in Western North America
TLDR
The map of 112 restriction sites in the mitochondrial DNA genome of the Speckled Dace suggested at least three separate ichthyofaunal invasions of California, as well as a Bonneville Basin fragmented by a north-south connection between southeastern Idaho and the Colorado River.

Evolution of the Mitochondrial Cytochrome Oxidase II Gene in Collembola
TLDR
The collembolan COII gene showed the lowest A +T content of all insects so far examined, confirming that the well-known A + T bias in insect mitochondrial genes tends to increase from the basal to apical orders.
Evolutionary Relationships of Minnows in the Genus Luxilus (Teleostei: Cyprinidae) as Determined from Cytochrome b Sequences
TLDR
General concordance of these results with those based on morphological characters provides support for a close relationship of the cornutus and zonatus groups and for basal position of the coccogenis group.
Phylogenetic Relationships of the Creek Chubs and the Spine‐Fins: an Enigmatic Group of North American Cyprinid Fishes (Actinopterygii: Cyprinidae)
TLDR
The analyses support recognition of Snyderichthys, formerly considered a subgenus of Gila, and indicate that the Plagopterin Clade is sister to the Creek Chub Clade, indicating that hypotheses of relationship between plagopterins and other Western taxa are unsupported and the Open Posterior Myodome Clades is a monophyletic group.
INFERRING PHYLOGENIES FROM mtDNA VARIATION: MITOCHONDRIAL‐GENE TREES VERSUS NUCLEAR‐GENE TREES

TLDR
An accurately resolved gene tree may not be congruent with the species tree because of lineage sorting of ancestral polymorphisms, but a survey of mtDNA‐haplotype diversity in 34 species of birds indicates that coalescence is generally very recent, which suggests that coalescent times are typically much shorter than internodal branch lengths of the species Tree, and that sorting of mt DNA lineages is not likely to confound the species trees.
Molecular Systematics and the Conservation of Rare Species
: Despite the tradition of systematic biology as the science of diversity, systematics has until recently contributed relatively little to the theory and practice of conservation biology. We identify…
Separating population structure from population history: a cladistic analysis of the geographical distribution of mitochondrial DNA haplotypes in the tiger salamander, Ambystoma tigrinum.
TLDR
This paper shows how a nested cladistic analysis of geographical distances can be used to test the null hypothesis of no geographical association of haplotypes, test the hypothesis that significant associations are due to restricted gene flow, and identify patterns of significant association that is due to historical events.
MOLECULAR CONTRIBUTIONS TO CONSERVATION
TLDR
A broad range of cases in which molecular techniques have been used to provide insight into conservation efforts is presented, rather than showcasing exhaustive details from a few well-known examples.
Intraspecific Cladogram Estimation: Accuracy at Higher Levels of Divergence
TLDR
This method has greater statistical power and more accurately reconstructs phylogenetic relationships than does maximum parsimony when few molecular characters are available for analysis, even at higher levels of diversification.
Populations, Genetic Variation, and the Delimitation of Phylogenetic Species
TLDR
Cl cladistic relationships as representative of phylogenetic relationships requires two conditions, both of which were identified by Hennig (1966, Phylogenetic systematics, Univ. Illinois Press, Urbana).
Nested clade analyses of phylogeographic data: testing hypotheses about gene flow and population history
TLDR
It is shown that nested phylogeographical analyses have more power to detect geographical associations than traditional, nonhistorical analyses and, as a consequence, allow a broader range of gene‐flow parameters to be estimated in a precise fashion.
