AbstractThe habitat relationships of the white-throated woodrat (Neotoma albigula albigula) and the plains woodrat (Neotoma micropus canescens) were studied in the Rio Grande Valley of southern New Mexico from May, 1964, to August, 1965. These two species of woodrats were found coexisting where they had been described in different habitats in 1907. Alterations in vegetation caused by farming and ranching practices appear to be the cause of the breakdown in habitat separation of the woodrats. The carrying capacity in woodrat habitat is probably determined by food in this area. Woodrats are absent where Yucca elata is absent, except in the foothill arroyos. Wherever Neotoma micropus was found, N. albigula was also found in this study. However, albigula was found in the apparent absence of micropus in some areas.
