Carbon and evapotranspiration dynamics of a non-native perennial grass with biofuel potential in the southern U.S. Great Plains
(Elsevier BV, 2019-05-15)Old world bluestem cultivar WW-B Dahl [Bothriochloa bladhii (Retz.), S. T. Blake] is a non-native perennial C4 bunch grass with biofuel production potential grown predominantly in the Southern U.S. Great Plains. Although ... -
Concentration of human erythrocytes by anopheline mosquitoes (Diptera: Culicidae) during feeding
(Oxford University Press (OUP), 1991-11)Erythrocyte densities in the blood meals of six Anopheles mosquito species were compared with those of human host erythrocyte densities. During engorgement, An. gambiae Giles and An. stephensi Liston concentrated erythrocytes ... -
Contributions of temporal segregation, oviposition choice, and non-additive effects of competitors to invasion success of Aedes japonicus (Diptera: Culicidae) in North America
(Springer Science and Business Media LLC, 2014-12-17)The mosquito Aedes japonicus (Diptera: Culicidae) has spread rapidly through North America since its introduction in the 1990s. The mechanisms underlying its establishment in container communities occupied by competitors ... -
County scale distribution of Amblyomma americanum (Ixodida: Ixodidae) in Oklahoma: Addressing local deficits in tick maps based on passive reporting
(Oxford University Press (OUP), 2015-03)Geographic distribution records for the lone star tick [Amblyomma americanum (L.)] in the peer-reviewed literature are incomplete for Oklahoma, preventing accurate disease risk assessments. To address this issue and document ... -
Differences in mosquito communities in six cities in Oklahoma
(Oxford University Press (OUP), 2019-04-05)Vector-borne diseases in the United States have recently increased as a result of the changing nature of vectors, hosts, reservoirs, pathogens, and the ecological and environmental conditions. Current information on vector ... -
Effect of two commercial herbicides on life history traits of a human disease vector, Aedes aegypti, in the laboratory setting
(Springer Science and Business Media LLC, 2016-03-10)Some mosquito species utilize the small niches of water that are abundant in farmland habitats. These niches are susceptible to effects from agricultural pesticides, many of which are applied aerially over large tracts of ... -
Elution independent collection device (EICD) for rapid collection of Anaplasma marginale DNA from blood samples
(Elsevier BV, 2022-01)Currently utilized molecular detection methods are based mainly on nucleic acid extraction, amplification, and detection procedures that may require costly equipment, numerous reagents, and highly trained personnel. These ... -
Exflagellation responses of cultured Plasmodium falciparum (Haemosporida: Plasmodiidae) gametocytes to human sera and midguts of anopheline mosquitoes (Diptera: Culicidae)
(Oxford University Press (OUP), 1994)The process of exflagellation was quantified for cultured Plasmodium falciparum gametocytes exposed to human sera and midgut homogenates from six vector species of Anopheles mosquitoes. Neither serum factors related to ... -
First detection of Rickettsia typhi and Rickettsia felis in fleas collected from client-owned companion animals in the southern Great Plains
(Oxford University Press (OUP), 2017-03-25)Flea-borne rickettsiosis occurs worldwide and includes a number of pathogens, namely, Rickettsia typhi and Rickettsia felis. Most studies in the United States have occurred in southern Texas and California where flea-borne ... -
Invasive woody plants as foci of tick-borne pathogens: Eastern redcedar in the southern Great Plains
(Society for Vector Ecology, 2021-06)Habitat preference and usage by disease vectors are directly correlated with landscapes often undergoing anthropogenic environmental change. A predominant type of land use change occurring in the United States is the ... -
Involvement of invasive eastern red cedar (Juniperus virginiana) in the expansion of Amblyomma americanum in Oklahoma

Mapping of schistosomiasis and soil-transmitted helminths in Namibia: The first large-scale protocol to formally include rapid diagnostic tests
(Public Library of Science (PLoS), 2015-07-21)Background: Namibia is now ready to begin mass drug administration of praziquantel and albendazole against schistosomiasis and soil-transmitted helminths, respectively. Although historical data identifies areas of transmission ... -
Molecular identification of Rickettsia typhi and R. felis in co-infected Ctenocephalides felis (Siphonaptera: Pulicidae)
(Oxford University Press (OUP), 1998)Rickettsia typhi and R. felis, 2 closely related rickettsial species, often have been identified in cat fleas, Ctenocephalides felis (Bouche) from the same geographical location. However, no fleas have been found to be ... -
Mosquito-borne parasites in the Great Plains: Searching for vectors of nematodes and avian malaria parasites
(Elsevier BV, 2021)Vector-borne diseases in the United States have recently increased as a result of the changing nature of vectors, hosts, reservoirs, parasite/pathogens, and the ecological and environmental conditions. While most focus has ... -
