Sensitivity of transects across a depth gradient to measuring changes in aerial coverage and abundance of Ruppia megacarpa Mason (Page 1)

Sensitivity of transects across a depth gradient to measuring changes in aerial coverage and abundance of Ruppia megacarpa Mason

Effective management of estuarine systems that contain submerged aquatic macrophytes, requires knowledge of whether macrophyte populations are stable, increasing or decreasing in terms of aerial coverage and abundance. This study established three transects within Wilson Inlet and monitored them five times during 1996 for percent cover of Ruppia megacarpa and maximum depth limits of these meadows.

Sydney rock oyster, Saccostrea commercialis (Iredale & Roughley), filtration of shrimp farm effluent: the effects on water quality (Page 1)

Sydney rock oyster, Saccostrea commercialis (Iredale & Roughley), filtration of shrimp farm effluent: the effects on water quality

Jones AB and Preston NP ·
1999

Shrimp pond effluent water can contain higher concentrations of dissolved nutrients and suspended particulates than the influent water. Consequently, there are concerns about adverse environmental impacts on coastal waters caused by eutrophication and increased turbidity. One potential method of improving effluent water quality prior to discharge or recirculation is to use bivalves to filter the effluent.

Temperature, salinity and food effects on asexual reproduction and abundance of the scyphozoan Chrysaora quinquecirrha

Purcell JE, White JR, Nemazie DA, and Wright DA ·
1999

Outbreaks of jellyfish are reported worldwide, yet the environmental factors that control the sizes of jellyfish populations are not well understood. The scyphomedusan Chrysaora quinquecirrha occurs in the mesohaline portion of Chesapeake Bay each summer. Population sizes of the medusae show dramatic annual variations that are correlated with salinity and temperature.

Within canopy growth strategies of the two seagrass species Amphibolis griffithii (J. Black) den Hartog and Amphibolis antarctica (Labillardiere) Sonder & Ascherson ex Ascherson (Page 1)

Within canopy growth strategies of the two seagrass species Amphibolis griffithii (J. Black) den Hartog and Amphibolis antarctica (Labillardiere) Sonder & Ascherson ex Ascherson

Carruthers TJB ·
1999

Responses in leaf production to variation in light climate throughout Amphibolis griffithii and A.antarctica canopies were studied at Rottnest Island, Western Australia. To test the importance of small scale changes in the physical environment (e.g. light, temperature and water movement) within the canopy, leaf production rates at different heights within the canopies and Radiation Use Efficiency (RUE), for the entire canopy of each species, were calculated and compared.

Moreton Bay and Catchment (Page 1)

Moreton Bay and Catchment

Tibbetts IR, Narelle JH and Dennison WC (Editors) ·
1 December 1998

This book is the proceedings of the Moreton Bay and Catchment conference. It is divided into nine major sections covering the environmental history of the region, geology and geomorphology, catchment rivers and lakes, water quality, marine plants, marine animals, corals, flood effects and management options. The conference was preceded by a relatively small flood, which served as an opportunity to study the impact of flood events on Moreton Bay.
