Ecophysiology of the marine cyanobacterium, Lyngbya majuscula (Oscillatoriaceae) in Moreton Bay, Australia (Page 1)

Ecophysiology of the marine cyanobacterium, Lyngbya majuscula (Oscillatoriaceae) in Moreton Bay, Australia

Watkinson AJ, O'Neil JM, and Dennison WC ·
2005

Large blooms of the marine cyanobacterium Lyngbya majuscula in Moreton Bay, Australia (27 degrees 05'S, 153 degrees 08'E) have been re-occurring for several years. A bloom was studied in Deception Bay (Northern Moreton Bay) in detail over the period January-March 2000. In situ data loggers and field sampling characterised various environmental parameters before and during the L. majuscula bloom.

Healthy Waterways, Healthy Catchments (Page 1)

Healthy Waterways, Healthy Catchments

Abal EG, Bunn SE and Dennison WC ·
1 January 2005

This book was the fourth in a series of publications in support of the Heathy Waterways campaign in Southeast Queensland, Australia. It synthesizes the scientific investigations focused on the catchments and waterways of the Southeast Queensland region. Chapters on the setting, habitats, sediments, nutrients, monitoring, modeling, harmful algal blooms integrate the various scientific studies occurring in the region.

Quantifying and evaluating ecosystem health: A case study from Moreton Bay, Australia (Page 1)

Quantifying and evaluating ecosystem health: A case study from Moreton Bay, Australia

Pantus FJ and Dennison WC ·
2005

As part of the program monitoring the ecosystem health of Moreton Bay, Queensland, Australia, we developed a means for assessing ecosystem health that allows quantitative evaluation and spatial representations of the assessments. The management objectives for achieving ecosystem health were grouped into ecosystem objectives, water quality objectives, and human health objectives.

A comparison of issues and management approaches in Moreton Bay, Australia and Chesapeake Bay, USA (Page 1)

A comparison of issues and management approaches in Moreton Bay, Australia and Chesapeake Bay, USA

Dennison WC, Carruthers TJB, Thomas JE, and Glibert PM ·
2004

Management of coastal systems is becoming increasingly important, however understanding the process of effective management often remains elusive. This chapter contrasts examples of environmental problems and associated management in Moreton Bay, Australia, and Chesapeake Bay, USA. Targeted research in Moreton Bay identified specific issues which led to changed practices, while intense management and research in Chesapeake Bay has been unable to keep pace with increasing anthropogenic stress.

Assessing ecological impacts of shrimp and sewage effluent: Biological indicators with standard water quality analyses (Page 1)

Assessing ecological impacts of shrimp and sewage effluent: Biological indicators with standard water quality analyses

Jones AB, O'Donohue MJ, Udy J, and Dennison WC ·
2001

Despite evidence linking shrimp farming to several cases of environmental degradation, there remains a lack of ecologically meaningful information about the impacts of effluent on receiving waters. The aim of this study was to determine the biological impact of shrimp farm effluent, and to compare and distinguish its impacts from treated sewage effluent.

Discover the waterways of South East Queensland (Page 1)

Discover the waterways of South East Queensland

Bill Dennison ·
1 January 2001

This book was the third in a series of publications in support of the Healthy Waterways campaign in Southeast Queensland, Australia. It provides a guide for citizens to view various features of the waterways from specified vantage points. Grounded in the scientific understanding developed for the region, this book is an invitation to 'see it for yourself'. The book includes maps, conceptual diagrams, photos and 'catchment comments' from community leaders.

Effects of concentrated viral communities on photosynthesis and community composition of co-occurring benthic microalgae and phytoplankton (Page 1)

Effects of concentrated viral communities on photosynthesis and community composition of co-occurring benthic microalgae and phytoplankton

Hewson I, O'Neil JM, Heil CA, Bratbak G, and Dennison WC ·
2001

Marine viruses have been shown to affect phytoplankton productivity; however, there are no reports on the effect of viruses on benthic microalgae (microphytobenthos). Hence, this study investigated the effects of elevated concentrations of virus-like particles on the photosynthetic physiology and community composition of benthic microalgae and phytoplankton.

Virus-like particles associated with Lyngbya majuscula (Cyanophyta; Oscillatoriacea) bloom decline in Moreton Bay, Australia (Page 1)

Virus-like particles associated with Lyngbya majuscula (Cyanophyta; Oscillatoriacea) bloom decline in Moreton Bay, Australia

Hewson I, O'Neil JM, and Dennison WC ·
2001

Expansive blooms of the toxic cyanobacterium Lyngbya majuscula were observed in 2 shallow water regions of Moreton Bay, Australia. The rapid bloom decline (8 to <1 km(2) in <7 d) prompted an investigation of the role of cyanophage viruses in the ecophysiology of L. majuscula. Virus-like particles produced by decaying L. majuscula were observed using electron microscopy. The virus-like particles were similar in morphology to viruses in the genus Cyanostyloviridae.

Effect of the seagrass Zostera capricorni on sediment microbial processes (Page 1)

Effect of the seagrass Zostera capricorni on sediment microbial processes

Hansen JW, Udy JW, Perry CJ, Dennison WC, and Lomstein BA ·
2000

The effect of the seagrass Zostera capricorni on sediment microbial processes was studied in a tank experiment, where vegetated and unvegetated control sediments were incubated in 10 and 50% of incident light. Leaf and root-rhizome biomass, shoot density, and leaf productivity were significantly higher when plants were incubated in 50 % than in 10 % of incident Light.

Physiological responses of five seagrass species to trace metals (Page 1)

Physiological responses of five seagrass species to trace metals

Prange JA and Dennison WC ·
2000

Trace metal run-off associated with urban and industrial development poses potential threats to seagrasses in adjacent coastal ecosystems, Seagrass from the largest urban (Moreton Bay) and industrial (Port Curtis) coastal regions in Queensland, Australia were assessed for metal concentrations of iron (Fe), aluminium (Al), zinc (Zn), chromium (Cr) and copper (Cu), Trace metal concentrations in seagrass (Zostera capricorni) leaf and root-rhizome tissue had the following overall trend:
