Four species of spotted skunks (Carnivora, Mephitidae, Spilogale) are currently recognized: Spilogale angustifrons, S. gracilis, S. putorius, and S. pygmaea. Understanding species boundaries within this group is critical for effective conservation given that regional populations or subspecies (e.g., S. p. interrupta) have experienced significant population declines. Further, there may be currently unrecognized diversity within this genus as some taxa (e.g., S. angustifrons) and geographic… 
Pattern and timing of mitochondrial divergence of island spotted skunks on the California Channel Islands
Island spotted skunks (Spilogale gracilis amphiala) are a rare subspecies endemic to the California Channel Islands, currently extant on Santa Cruz and Santa Rosa islands. How and when skunks arrived
Mitochondrial Genomes of the United States Distribution of Gray Fox (Urocyon cinereoargenteus) Reveal a Major Phylogeographic Break at the Great Plains Suture Zone
Despite broad-scale sampling, Gray foxes in the United States displayed a deep, cryptic divergence suggesting taxonomic revision is needed, and secondary contact at a common phylogeographic break, the Great Plains Suture Zone, suggests ongoing evolutionary processes may reinforce this divergence.
The Relevance of a Type Locality: the Case of Mephitis interrupta Rafinesque, 1820 (Carnivora: Mephitidae)
For more than 130 years, the type locality of the Plains Spotted Skunk, Spilogale putorius interrupta (Rafinesque, 1820) has been accepted to be along the upper Missouri River. The species'
Itching for Recognition: Dermatophytosis Identified in an Eastern Spotted Skunk (Spilogale putorius) Population in Texas
Abstract The diversity, clinical manifestations, and impact on overall health of pathogenic fungi in Spilogale putorius (Eastern Spotted Skunk [ESS]) have been poorly investigated. Herein, we


Genetic variation in the eastern spotted skunk (Spilogale putorius) with emphasis on the plains spotted skunk (S. p. interrupta)
Overall, genetic variability in the plains spotted skunk was lower than that seen in common carnivores (e.g., striped skunks, Mephitis mephitis, and raccoons, Procyon lotor), but slightly higher than in the endangered black-footed ferret (Mustela nigripes).
Phylogeography of striped skunks (Mephitis mephitis) in North America: Pleistocene dispersal and contemporary population structure
It appears that periodic Pleistocene glacial expansions and retreats caused a series of range expansions and secondary contact events in this native North American species to create a complex pattern of population structure today.
Evolutionary history of the critically endangered Cozumel dwarf carnivores inferred from mitochondrial DNA analyses
Although it is likely that the island taxa colonized Cozumel before the Mayan peoples populated the island, the hypothesis that colonization by these taxa was not human facilitated is unable to definitively reject.
Molecular Phylogeography of Harvest Mice (Reithrodontomys megalotis) Based on Cytochrome b DNA Sequences
It is suggested that populations of R. megalotis have probably developed considerable phenotypic plasticity whose analysis and description should be approached from an ecological more than historical perspective.
Genetic differentiation of island spotted skunks, Spilogale gracilis amphiala
The results indicate that the taxonomic status of the island spotted skunk should be reconsidered and that both island populations might constitute evolutionarily significant units worthy of conservation.
Biogeographically dynamic genetic structure bridging two continents in the monotypic Central American rodent Ototylomys phyllotis
The results support monophyly of the genus Ototylomys and identify three major phylogeographical lineages within O. phyllotis that are linked to its diversification and coincide with the main geological features that shaped Middle America.
A Comparative Analysis of Genetic Diversity and Structure in Jaguars (Panthera onca), Pumas (Puma concolor), and Ocelots (Leopardus pardalis) in Fragmented Landscapes of a Critical Mesoamerican Linkage Zone
The first genetic study on wild populations of multiple Neotropical felids coexisting across a fragmented landscape in Belize shows the value of understanding fine-scale patterns of gene flow in multiple co-occurring felid species of conservation concern, which is vital for wildlife movement corridor planning and prioritizing future conservation and management efforts within human-impacted landscapes.
Phylogeography of a widespread small carnivore, the western spotted skunk (Spilogale gracilis) reveals temporally variable signatures of isolation across western North America
This study supports PPD in shaping species‐level diversity compared to QCC‐driven changes at the intraspecific level for Spilogale, similar to the patterns reported for other small mammals.
Taxonomic status of southern South American Conepatus (Carnivora: Mephitidae)
It is indicated that environmental variation seems to be responsible for shape and size variation in Conepatus skulls from southern South America.
Evolutionary Significant Units versus Geopolitical Taxonomy: Molecular Systematics of an Endangered Sea Turtle (genus Chelonia)
The arguments for and against the species status of the endangered black turtle are explored, a pragmatic category for this type of taxonomy is proposed: the geopolitical species is proposed, and the practice of pre- serving species status for conservation purposes is argued.
