| survey for evidence of colorado tick fever virus outside of the known endemic area in california. | a virus very similar or identical to colorado tick fever (ctf) virus was recovered from the blood clot of one of 104 black-tailed jack rabbits (lepus californicus) examined during a survey for various zoonotic agents in mammals and ticks from the university of california, hopland field station, mendocino county, california, 1974--79. this is the first reported isolation of a ctf-like virus from l. californicus, and only the second time such a virus has been found in northwestern california. mend ... | 1982 | 7102919 |
| reservoir competence of four chaparral-dwelling rodents for borrelia burgdorferi in california. | aspects of the reservoir competence of four rodents for the lyme disease spirochete, borrelia burgdorferi, were evaluated in california. rodents were live-trapped and ear-punch biopsies were cultured during each season. a second set of biopsies was cultured from representative individuals after 2-3 weeks of captivity and the results of culturing biopsies taken on both dates were compared with the results of feeding ixodes pacificus larvae on hosts xenodiagnostically. the prevalence of infections ... | 1996 | 8651378 |

| role of small mammals in the ecology of borrelia burgdorferi in a peri-urban park in north coastal california. | the role of small mammals other than woodrats in the enzootiology of the lyme disease spirochete, borrelia burgorferi, was assessed in the peri-urban park. mammals were collected monthly from september through to april. following tick removal, the animals were tested for b. burgdorferi by culture of ear-punch biopsies. larvae and nymphs that were intermediate in morphology between ixodes spinipalpis and ixodes neotomae occurred on several species of rodents (peromyscus truei, peromyscus californ ... | 1997 | 9291589 |
| cross-transmission studies with eimeria arizonensis, e. arizonensis-like oocysts and eimeria langebarteli: host specificity at the genus and species level within the muridae. | cross-transmission experiments were done using sporulated oocysts of eimeria arizonensis from peromyscus truei and peromyscus maniculatus, and oocysts of 2 putative species that resemble e. arizonensis, i.e., eimeria albigulae from neotoma albigula, and eimeria onychomysis from onychomys leucogaster. oocysts of each species were inoculated into representatives of p. maniculatus and the latter 2 rodent species. other experiments were conducted wherein oocysts of eimeria langebarteli from peromysc ... | 1999 | 10577723 |
| experimental evaluation of rodent exclusion methods to reduce hantavirus transmission to residents in a native american community in new mexico. | we conducted a pilot study to evaluate the efficacy of rodent proofing continuously occupied homes as a method for lowering the risk for hantavirus pulmonary syndrome (hps) among residents of a native american community in northwestern new mexico. rodent proofing of dwellings was paired with culturally appropriate health education. seventy homes were randomly assigned to treatment or control categories. treatment homes were rodent-proofed by sealing openings around foundations, doors, roofs, and ... | 2002 | 12653299 |
| effectiveness of six species of rodents as dispersers of singleleaf piñon pine (pinus monophylla). | the effectiveness of six species of rodents as dispersers of singleleaf piñon pine (pinus monophylla) was investigated in field enclosures. the rodent species were panamint kangaroo rat (dipodomys panamintinus), great basin pocket mouse (perognathus parvus), pinyon mouse (peromyscus truei), deer mouse (peromyscus maniculatus), least chipmunk (tamias minimus), and white-tailed antelope ground squirrel (ammospermophilus leucurus). five measures of seed harvesting and caching behavior were assessed ... | 2004 | 14534782 |
| seed-caching responses to substrate and rock cover by two peromyscus species: implications for pinyon pine establishment. | we examined whether pinyon mice ( peromyscus truei) and brush mice ( p. boylii) could act as directed dispersal agents of pinyon pine ( pinus edulis) through differential responses to soil particle size and rock cover. in field experiments, we allowed mice to either cache pinyon seeds or recover artificially cached seeds (pilfer) from quadrats containing large- or small-particle soils. both species placed most (70%) seed caches in small-particle soil. pilfering was the same from both particle si ... | 2004 | 15258848 |
| reproductive protein evolution within and between species: maintenance of divergent zp3 alleles in peromyscus. | in a variety of animal taxa, proteins involved in reproduction evolve more rapidly than nonreproductive proteins. most studies of reproductive protein evolution, however, focus on divergence between species, and little is known about differentiation among populations within a species. here we investigate the molecular population genetics of the protein zp3 within two peromyscus species. zp3 is an egg coat protein involved in primary binding of egg and sperm and is essential for fertilization. we ... | 2008 | 18466231 |
| the pox in the north american backyard: volepox virus pathogenesis in california mice (peromyscus californicus). | volepox virus (vpxv) was first isolated in 1985 from a hind foot scab of an otherwise healthy california vole (microtus californicus). subsequent surveys in san mateo county, ca, revealed serological evidence suggesting that vpxv is endemic to this area, and a second viral isolate from a pinyon mouse (peromyscus truei) was collected in 1988. since then, few studies have been conducted regarding the ecology, pathology, and pathogenicity of vpxv, and its prevalence and role as a potential zoonotic ... | 2012 | 22952799 |

| flea (siphonaptera) species richness in the great basin desert and island biogeography theory. | numbers of flea (siphonaptera) species (flea species richness) on individual mammals should be higher on large mammals, mammals with dense populations, and mammals with large geographic ranges, if mammals are islands for fleas. i tested the first two predictions with regressions of h. j. egoscue's trapping data on flea species richness collected from individual mammals against mammal size and population density from the literature. mammal size and population density did not correlate with flea s ... | 2014 | 24820569 |
