Cactus Deermouse – Peromyscus eremicus

Peromyscus eremicusBaird, 1857

Accepted name, Mammal Species of the World 2005

P. eremicus species group. Once included P. merriami (see Hoffmeister and Lee, 1963a), P. eva (see Lawlor, 1971b), and P. fraterculus (see Riddle et al., 2000a, c). Even following removal of these several species confused under eremicus, mitochondrial DNA variation delineates well-marked W (Sonoran) and E (Chihuahuan) lineages whose taxonomic status should be explored (see Walpole et al., 1997; Riddle et al., 2000c). Lawlor (1971a) relegated the population on Isla Turner, collatus, to subspecies, a relationship and ranking bolstered by molecular analyses (Hafner et al., 2001), but Hall (1981) and Alvarez-Castañeda and Cortés-Calva (1999) continued to list it as a species. Relationships of P. eremicus to various insular forms in Gulf of California elucidated first by Lawlor (1971a, b, 1983) and later Hafner et al. (2001). Genetic variation broadly s... [truncated]
