A popular animal model first used in polio research, which is a model of choice for research in measles—paramyxovirus—herpes simplex, influenza—orthomyxovirus—HIV-1, respiratory syncytial virus, and adenovirus-based gene replacement research
In our analyses, we have sought: (1) to confirm cotton rats as the culprit by examining the relationship between cotton rat density and recent girdling activity as well as where cotton rats were present in the past in relation to old girdling activity, (2) to learn whether certain size classes of pines were selected over others, presumably because of their differential nutritional value, and (3) to determine how pine density influences the extent of girdling damage and evaluate the possible ecological role of cotton rats in succession.
During a recent investigation involving the use of radiotelemetry to study the movement patterns of the hispid cotton rat (Sigmodon hispidus), we documented several occurrences of predation on transient cotton rats.
The three most common species in the small-mammal community are cotton rats (Sigmodon hispidus), prairie voles (Microtus ochrogaster), and deer mice (Peromyscus maniculatus), which collectively comprise nearly 95% of the total trap records from the site (J.
Herein, we evaluated the population dynamics and ecology of southern bog lemmings and woodland voles as the dominant rodents in the absence of the larger and usually dominant oldfield meadow voles, cotton rats, and rice rats in our region.
Kidney samples from the 3 antibody-positive Mexican deer mice, Mexican deer mouse TK93314 (15) and 8 other antibody-negative Mexican deer mice, 18 southern pygmy mice (Baiomys musculus), and 11 Jaliscan cotton rats (Sigmodon mascotensis) were tested for arenavirus by cultivation in monolayers of Vero E6 cells (16).
