Four rodent species captured in the study area have been previously identified as potential hantavirus reservoir species: Peromyscus
Weight and pelage color were used to separate Peromyscus
juveniles from adults and sub-adults; for both species of Peromyscus
non-reproductive juveniles were < 16 g.
A total of 95 Peromyscus
mice (trap success 51%) were collected: 73 P.
3) found Peromyscus
leucopus to be somewhat of a "habitat generalist" because it was collected in diverse riparian settings ranging from woodlands with a lush, thick understory and ground cover to more xeric ones with sparse groundcover and no understory.
In our study, five spirochetes, based on cell morphology, were isolated from the hearts of Peromyscus
maniculatus and Myodes gapperi around the Turtle River and Forest River areas of Grand Forks, ND.
The two species of Peromyscus
at the study area exhibited very little habitat overlap, with P.
Six hantavirus-associated rodent species occur in Texas, including Microtus ochrogaster, Oryzomys palustris, Peromyscus
the pinon deer mouse, Peromyscus
truei) or expanded their upper range upslope while maintaining a stable lower range limit (e.
Maniculatus or deer mouse is described as a small, white-footed mouse with sharply bicolor tail, white beneath and dark above with ears usually shorter than hind foot, prominent and leaflike.
The species Linnen and Hoekstra studied, Peromyscus
maniculatus, is the most widespread mammal in North America.
fontinella are probably the cotton mouse, Peromyscus
gossypinus (Leconte), golden mouse, Ochrotomys nuttalli (Harlan) and Florida mouse, Podomys floridanus (Chapman) (Pearson 1954; Layne 1963; Bigler & Jenkins 1975).
