Control of cyanobacterial blooms in weir pools

Autor: Webster, I. T, Jones, G. J, Oliver, R. L, Bormans, M, Sherman, B. S

Murray-Darling Freshwater Research CentreMDFRC item.This paper describes research work on the effects of river flows on occurrence of cyanobacterial blooms in the relatively slow-flowing pools behind the regulatory weirs on the Murray-Darling river s

Buoyancy and suspension of planktonic cyanobacteria

Autor: Oliver, R. L, Walsby, A. E

Murray-Darling Freshwater Research CentreMDFRC item.Cyanobacteria are unique among phytoplankton in their ability to controltheir depth in lakes by buoyancy regulation. They derive their buoyancyfrom gas vesicles, which if present in sufficient quant

Optical properties, of waters in the Murray-Darling Basin, South-eastern Australia

Autor: Oliver, R. L

Murray-Darling Freshwater Research CentreMDFRC item.Apparent and inherent optical properties were determined for a range of water types in the Murray- Darling basin by using a combination of field and laboratory techniques. The absorption coefficient

Optical properties of Gas-vacuolate cells and colonies of Microcystis in relation to light attenuation in a turbid, stratified reservoir (Mount Bold Reservoir, South Australia)

Autor: Ganf, G. G, Oliver, R. L, Walsby, A. E

Murray-Darling Freshwater Research CentreMDFRC item.Profiles of downwelling and upwelling irradiance were measured in a stratified, turbid reservoir, when Microcystis aeruginosa formed a significant proportion of the phytoplankton community. The atte

The role of gas vacuoles and carbohydrate content in the buoyancy and vertical distribution of Anabaena minutissima in Lake Rotongaio, New Zealand

Autor: Walsby, A. E, Reynolds, C. S, Oliver, R. L, Kromkamp, J

Murray-Darling Freshwater Research CentreMDFRC item.The late summer phytoplankton of Lake Rotongaio contained an almost pure population of Anabaena minutissima var. attenuata, a gas vacuolate species producing thin solitary filaments. The population

Physiology of geosim production by Anabaena circinalis isolated from the Murrumbidgee River, Australia

Autor: Bowmer, K. H, Padovan, A, Oliver, R. L, Korth, W, Ganf, G. G

Murray-Darling Freshwater Research CentreMDFRC item.Chemical analysis and sensory assessment of river waters from the Murrumnidgee and Murray River showed geosim is an important odor compound. Experiments in culture using Anabaena circinalis isolated
