| cotton rats and other small mammals as hosts for immature dermacentor variabilis (acari: ixodidae) in central oklahoma. | eight species of small mammals were evaluated as potential hosts for american dog ticks, dermacentor variabilis (say), in an upland, tallgrass prairie study site in central oklahoma. only hispid cotton rats, sigmodon hispidus, and deer mice, peromyscus maniculatus, were found to be important hosts for immature d. variabilis. although d. varibilis larvae and nymphs frequently infested both cotton rats and deer mice, cotton rats were the most important host species for both immature stages in the ... | 1992 | 1404263 |
| coccidian parasites (apicomplexa) from snakes in the southcentral and southwestern united states: new host and geographic records. | four hundred thirty-five leptotyphlopid, colubrid, elapid, and viperid snakes were collected from various localities in arkansas, new mexico, oklahoma, and texas, and their feces were examined for coccidian parasites. of these, 131 (30%) were passing oocysts or sporocysts of at least 1 coccidian; 88 (67%) of the infected snakes had only 1 species of coccidian when they were examined. aquatic and semiaquatic snakes accounted for 48% of the infections, whereas strictly terrestrial snakes comprised ... | 1995 | 7876980 |
| small mammals as indicators of short-term and long-term disturbance in mixed prairie. | disturbance by military maneuvers over short and long time scales may have differential effects on grassland communities. we assessed small mammals as indicators of disturbance by military maneuvers in a mixed prairie in southern oklahoma usa. we examined sites on two soil series, foard and lawton, across a gradient of disturbance intensity. a manova showed that abundance of small mammals was associated (p = 0.03) with short-term (cover of vehicle tracks) disturbance but was not associated (p = ... | 2008 | 17458511 |
