Development of juvenile culture techniques and testing of potential biomarkers of environmental stress in freshwater mussels (Bivalvia: Unionidae)
… of using river water in a flow-through culture system to rear juvenile freshwater mussels. The culture method placed juvenile mussels, confined in small dishes, into oval troughs supplied with untreated river water. Two of three years produced acceptable survival rates of 27% and 19% to …

Growth Response of Soil Algae to Tordon 101 Mixture
… observed on soil algae in field plots and in laboratory culture of algal species selected from those isolated from the plots.

The development and evaluation of a polymerase chain reaction assay for the diagnosis of mycobacterium tuberculosis infections
… (microscopy) and prolonged incubation periods (laboratory culture) . For these reasons various "rapid detection" methods have been developed but none of these meet all the requirements of sensitivity, specificity and rapidity. DNA probes, although rapid, only have a sensitivity similar to that …

Characterizing cobalamin cycling by Antarctic marine microbes across multiple scales
… multiple spatiotemporal scales. I conducted laboratory culture experiments with complementary proteomics and transcriptomics to investigate the B₁₂-ecophysiology of P. antarctica strain CCMP 1871 morphotypes under iron-B₁₂ co-limitation.

The biology and ecology of Bifurcaria brassiceaformis (Kütz) Barton (Phaeophyta, Fucales)
… tolerances (temperature and light) in laboratory culture, of the endemic intertidal South African fucoid Bifurcaria brassicaeformis (Kütz) Barton have been investigated. A general description is included of the morphology and anatomy, and comparisons made with that of other species in …

The physiology of the genus bacillus
… the metabolism of these organisms in pure laboratory culture and also in mixed cultures in the natural habitat.

Estimating phytoplankton growth rates from compositional data
… then test this model with a set of data from a laboratory culture whose population growth rate was independently determined. In general, the parameter estimates I obtain for simulated data are better the lower the levels of stochasticity. Despite large confidence intervals around some model …

Laboratorization of Everyday Life: Adaptations among Robots, Laboratory and Society
… embodied in service robots, I show how both the laboratory culture and wider society expect their own respective values and environmental cultures to displace the other. This dissertation highlights the importance of understanding how robotics laboratories and larger society mutually transform …

The marine biogeochemistry of molybdenum
… and dissimilatory nitrate reduction. Laboratory culture work on two N2 fixing marine cyanobacteria, Trichodesmium and Crocosphaera, and a marine facultative denitrifier, Marinobacter hydrocarbanoclasticus, showed that Mo cell quotas in these organisms were positively correlated with …

Untangling Genomes from Metagenomes
… the vast majority remain inaccessible to laboratory investigation of their physiology and genetic potential, due to the difficulty of predicting and replicating the conditions they may require for growth. This is doubly true for viruses, where to isolate and study a given virus, a …

Factors that impact Pseudo-nitzschia spp. occurrence, growth, and toxin production
… in these waters. This is combined with laboratory studies examining key environmental factors and the multifactorial impact of multiple macronutrient and micronutrient availability on PN growth and DA production. An LC-MS method was established, optimised, and compared with ELISA for the …

The effects of elevated CO2 and ocean acidification on the production of marine biogenic trace gases
… 70,000 litre, high pCO2 mesocosm experiments and laboratory culture studies. DMS is a climatically important trace gas produced by marine algae: it transfers sulphur into the atmosphere and is a major influence on biogeochemical climate feedbacks. Halocarbons are also important biogenic trace …

A preliminary study of Gelidium capense in culture
… water movement, were performed under controlled laboratory culture conditions on the subtidal red alga Gelidium capense, with regards to its potential for aquaculture for its use in the agar and paper-making industries. Agar was also extracted from a wild population and its concentration …

Molecular characterization of organically bound copper in the marine environment
… decreased cell growth and even cell death. Laboratory culture experiments have shown that a diverse array of microbes produce organic ligands that complex Cu (CuL) and buffer the free ion concentration, which is the most bioavailable fraction. In this way, the microbes impose a control on …

Interactions Between The Nudibranch Okenia Zoobotryon And Its Bryozoan
… not significantly prefer Z. verticillatum. Next, laboratory culture of larvae of O. zoobotryon was performed. During larval culture some aspects of this previously undocumented life-history were recorded; adults of this species developed from planktotrophic veliger larvae that hatched out of egg …
