| factors affecting the seasonal abundance of ground squirrel and wood rat fleas (siphonaptera) in san diego county, california. | abiotic and biotic factors affecting the seasonal abundance of 3 species of sylvatic fleas on their hosts were examined at 7 sites in san diego county, california. indices for oropsylla (diamanus) montana (baker) were usually highest on spermophilus beecheyi nudipes (huey) when < 18.4 degrees c (october-december), whereas those for hoplopsyllus anomalus (baker) were highest when > 18.4 degrees c (july-september). o. montana was affected most by ambient temperature (inversely for the coastal site ... | 1996 | 8840686 |
| detection and characterization of borrelia bissettii in rodents from the central california coast. | this is the first report of borrelia burgdorferi sensu lato in rodents from san luis obispo county, with most isolates obtained from a previously unreported host, neotoma lepida thomas. b. burgdorferi sensu lato was identified in seven rodent species, including the california vole, microtus californicus peale; dusky-footed woodrat, neotoma fuscipes baird; desert woodrat, neotoma lepida thomas; brush mouse, peromyscus boylii baird; california mouse, peromyscus californicus gambel; deer mouse, per ... | 2004 | 15311469 |
| epizootiology of tacaribe serocomplex viruses (arenaviridae) associated with neotomine rodents (cricetidae, neotominae) in southern california. | the objective of this study was to advance our knowledge of the epizootiology of bear canyon virus and other tacaribe serocomplex viruses (arenaviridae) associated with wild rodents in california. antibody (immunoglobulin g [igg]) to a tacaribe serocomplex virus was found in 145 (3.6%) of 3977 neotomine rodents (cricetidae: neotominae) captured in six counties in southern california. the majority (122 or 84.1%) of the 145 antibody-positive rodents were big-eared woodrats (neotoma macrotis) or ca ... | 2015 | 25700047 |
| new host and locality records of coccidia (apicomplexa: eimeriidae) from rodents in the southwestern and western united states. | one hundred forty-seven murid and heteromyid rodents were collected from various sites in the southwestern and western united states (arizona, colorado, new mexico, texas, and utah) and baja california norte, mexico, and their feces were examined for coccidial parasites. of these, 53 (36%) were infected with at least 1 coccidian; 45 of 53 (85%) of the infected rodents harbored only 1 species of coccidian. infected rodents included: 10 of 22 (45%) neotoma albigula, 3 of 11 (27%) neotoma floridana ... | 1991 | 1779282 |
| arenavirus antibody in rodents indigenous to coastal southern california. | the purpose of this study was to extend our knowledge on the geographic and natural rodent host ranges of new world arenaviruses in california. sera from 1,094 sigmodontine and 112 murine rodents were tested for antibody against whitewater arroyo and amapari viruses. antibody was found in 55 (4.6%) of the 1,206 rodents: 4 from northwestern san diego county, 3 from los angeles county, and 48 from orange county. the antibody-positive rodents included 8 (7.8%) of 103 neotoma fuscipes, 1 (0.6%) of 1 ... | 2000 | 11289675 |
| experimental evidence for asymmetric mate preference and aggression: behavioral interactions in a woodrat (neotoma) hybrid zone. | female mate preferences may be under strong selection in zones of contact between closely related species because of greater variation in available mates and the potential costs of hybridization. we studied female mate preferences experimentally in a zone of secondary contact between desert and bryant's woodrat (neotoma lepida and n. bryanti) in the southern foothills of the sierra nevada of california. we tested female preference for conspecific versus heterospecific males in paired choice tria ... | 2013 | 24093823 |
