Lycalopex vetulus (Carnivora: Canidae)
Lycalopex vetulus (Lund, 1842), commonly called the hoary fox, is Brazil’s smallest canid. It has a slender body and limbs and a small skull composed of relative fragile bones. Its size and skull characteristics combined with its peculiar dentition make it more suitable for an insectivorous diet rather than one of large vertebrates. L. vetulus is endemic to Brazil and occurs primarily in the so...
متن کاملLycalopex gymnocercus (Carnivora: Canidae)
Lycalopex gymnocercus (Fischer, 1814) is a canid commonly called the Pampas fox. A sexually dimorphic fox-like carnivore of medium size with reddish coloration on sides and white on the ventral surface, it is 1 of 6 species in the genus Lycalopex. It occurs in eastern Bolivia, western and central Paraguay, Uruguay, north and central Argentina, and southeastern Brazil. It prefers open habitats b...
متن کاملMolecular assessment of the phylogeny and biogeography of a recently diversified endemic group of South American canids (Mammalia: Carnivora: Canidae)
To investigate the evolution and biogeography of an endemic group of South American foxes, we examined mitochondrial DNA control region sequences for 118 individuals belonging to all six extant species of the genus Lycalopex. Phylogenetic and molecular dating analyses supported the inference that this genus has undergone a very recent and rapid radiation, stemming from a common ancestor that li...
متن کاملComparative molecular phylogeny and evolution of sex chromosome DNA sequences in the family Canidae (Mammalia: Carnivora).
To investigate the molecular phylogeny and evolution of the family Canidae, nucleotide sequences of the zinc-finger-protein gene on the Y chromosome (ZFY, 924-1146 bp) and its homologous gene on the X chromosome (ZFX, 834-839 bp) for twelve canid species were determined. The phylogenetic relationships among species reconstructed by the paternal ZFY sequences closely agreed with those by mtDNA a...
متن کاملInterplay between metabolic rate and diet quality in the South 4 American fox ,
24 Abstract 25 26 We studied the metabolic costs associated with the ingestion of peppertree fruits (Schinus molle) in the culpeo fox, 27 Pseudalopex culpaeus, the second largest canid in South America. Throughout its range of distribution, this fox feeds 28 on rodents and other small vertebrates, and also on peppertree fruits, which represent 98% of total fruits consumed in 29 semiarid Chile. ...
