“…Our additional data from the Gulf Coast region supported the taxonomic conclusions of Dragoo et al (2003). Populations of hog-nosed skunks in southern Texas and northeastern Mexico might be more stable than previously suggested (e.g., Dragoo et al, 2003;Dragoo and Sheffield, 2009). Alternatively, populations may be re-expanding into formerly occupied areas.…”

“…Hog-nosed skunks (Conepatus leuconotus) are adapted for digging and rooting (Patton, 1974;Davis and Schmidly, 1994), and they have black pelage with one white dorsal stripe extending from forehead to tail (Dragoo, 2009;Dragoo and Sheffield, 2009). The historical distribution of hog-nosed skunks encompassed much of the southwestern United States and Mexico; however, current status of populations largely is unknown (Dragoo et al, 2003(Dragoo et al, , 2004Dragoo, 2009;Dragoo and Sheffield, 2009).…”

“…The historical distribution of hog-nosed skunks encompassed much of the southwestern United States and Mexico; however, current status of populations largely is unknown (Dragoo et al, 2003(Dragoo et al, , 2004Dragoo, 2009;Dragoo and Sheffield, 2009). Numerous reports suggested that populations, particularly along the Gulf Coast of Texas, have experienced severe declines associated with modifications of habitat (Schmidly, 1983;Dragoo et al, 2003;Dragoo, 2009), use of pesticides (Dragoo et al, 2003;Dragoo and Sheffield, 2009), and competition by wild boars (Sus scrofa; Dragoo et al, 2003). The lack of records of hog-nosed skunks from southern Texas has promoted speculation that populations have been extirpated (Dragoo et al, 2003).…”

“…Specifically, musteloid diets include fish and marine invertebrates [e.g., Lontra canadensis ; Larivière and Walton, ), small mammals, insects, fruits, eggs, and even bamboo ( Ailurus fulgens ; Roberts and Gittleman, )]. Within single families and genera, dietary diversification may be high: while the American hog‐nosed skunk ( Conepatus leuconotus ) is predominantly insectivorous, the Andean hog‐nosed skunk ( Conepatus chinga ) is a dedicated hypercarnivore, exploiting both small vertebrates and invertebrates (Donadio et al, ; Montalvo et al, ; Dragoo and Sheffield, ).…”

Dietary ecology and its relationship with both muscle architecture and bite force potential has been studied in many mammalian (and non‐mammalian) taxa. However, despite the diversity of dietary niches that characterizes the superfamily Musteloidea, the masticatory muscle fiber architecture of its members has yet to be investigated anatomically. In this study, we present myological data from the jaw adductors in combination with biomechanical data derived from craniomandibular measurements for 17 species representing all four families (Ailuridae, Mephitidae, Mustelidae, and Procyonidae) of Musteloid. These data are combined to calculate bite force potential at each of three bite points along the dental row. Across our sample as a whole, masticatory muscle mass scaled with isometry or slight positive allometry against both body mass and skull size (measured via a cranial geometric mean). Total jaw adductor physiological cross‐sectional area scaled with positive allometry against both body mass and skull size, while weighted fiber length scaled with negative allometry. From a dietary perspective, fiber length is strongly correlated with dietary size such that taxa that exploit larger foods demonstrated myological adaptations toward gape maximization. However, no consistent relationship between bite force potential and dietary mechanical resistance was observed. These trends confirm previous findings observed within the carnivoran family Felidae (as well as within primates), suggesting that the mechanisms by which masticatory anatomy adapts to dietary ecology may be more universally consistent than previously recognized.

“…Studies on different modern skunk species indicate that invertebrates compose the bulk of their diet but sometimes consume vertebrates such as small mammals, birds, reptiles and carrion (Larivière & Messier 2000; Widmann & Widmann 2004; Montalvo et al. 2008; Dragoo & Sheffield 2009). In the taphonomic study of the scats of the Andean hog‐nosed skunk ( Conepatus chinga ) carried out by Montalvo et al.…”

Domingo, M.S., Sánchez, I.M., Alberdi, M.T., Azanza, B. & Morales, J. 2011: Evidence of predation/scavenging on Moschidae (Mammalia, Ruminantia) from the Late Miocene of Spain. Lethaia, Vol. 45, pp. 386–400. Fossil remains belonging to three musk deer species (Moschidae) from the Late Miocene pseudo‐karstic fossil site of Batallones‐1 (Madrid, Spain) bear evidence of corrosion produced by digestive acids. Although moschid bones co‐occur with remains of several other vertebrate taxa, modifications due to digestion are restricted to the fossils of these ruminants. In this study, we focus on the particular taphonomic history undergone by the moschid assemblage. A description of the bone‐surface modifications together with an analysis of the skeletal part representation and bone breakage are provided. The absence in the fossil site of many moschid skeletal elements and fragments of long bones indicates that these ruminants were preyed on or consumed out of the cavity and eventually became part of the bone assemblage when their predator/scavenger became trapped. The features exhibited by the moschid fossiliferous assemblage allow the evaluation of the trophic interactions in this Late Miocene community. The ailurid Simocyon batalleri and the amphicyonid Magericyon anceps are potentially responsible for the moschid assemblage considering the taphonomical features exhibited by the musk deer remains (type and degree of digestive damage and bone breakage, size of the recovered remains) and the dietary adaptations and preferences of these carnivorans. Together, digestive corrosion traces and moschid bone assemblage characteristics provide strong evidence for specific predator‐prey interactions in a Miocene ecosystem.
