| ticks (acari: ixodidae) collected from small and medium-sized kansas mammals. | seven species of hard-bodied ticks were collected from 20 species of small and medium-sized mammals in kansas; amblyomma americanum l., dermacentor variabilis (say), haemaphysalis leporispalustris (packard), ixodes cookei packard, i. kingi bishopp, i. sculptus neumann, and i. texanus banks. dermacentor variabilis was found statewide, a. americanum only in the eastern one-third of the state, and the ixodes spp. and h. leporispalustris were widely scattered. the most common tick found was d. varia ... | 1994 | 8057327 |
| intraspecific variation in estrogen receptor alpha and the expression of male sociosexual behavior in two populations of prairie voles. | estrogen (e) regulates a variety of male sociosexual behaviors. we hypothesize that there is a relationship between the distribution of estrogen receptor alpha (eralpha) and the degree of male social behavior. to test this hypothesis, eralpha immunoreactivity (ir) was compared in prairie voles (microtus ochrogaster) from illinois (il), which are highly social, and kansas (kn), which are less social. the expression of androgen receptors (ar) in males also was compared between populations. the exp ... | 2004 | 15246861 |
| the effects of peptides on partner preference formation are predicted by habitat in prairie voles. | this study tested the hypothesis that intraspecific variations in mating systems are correlated with differences in the capacity of peripheral arginine vasopressin (avp) to facilitate partner preferences. it has been hypothesized that differences in environmental conditions, kansas being more xeric than illinois, are responsible for some of the intraspecific differences in the mating systems between kansas (kn) and illinois (il) prairie voles. we predicted that prairie voles from kn would be mor ... | 2001 | 11161883 |
| resistance of the prairie vole (microtus ochrogaster) and the woodrat (neotoma floridana), in kansas, to venom of the osage copperhead (agkistrodon contortrix phaeogaster). | prairie vole (microtus ochrogaster) serum has no anti-lysing or antibody activity against osage copperhead (agkistrodon contortrix phaeogaster) venom. however, the serum has an anti-hemorrhagic component, which significantly reduces the size of hemorrhage produced by the minimal hemorrhagic dose of venom and which blocks the minimal hemorrhagic dose at a dilution of 1/8. woodrat (neotoma floridana) serum also has an antihemorrhagic component which blocks the minimal hemorrhagic dose at a dilutio ... | 1982 | 6753240 |
