Spatially variable effects of copper on sessile invertebrates across a marina
A manipulative field experiment was used to assess the spatial variation in the effect of copper on sessile invertebrates within a marina in Port Phillip Bay, Victoria. Sessile... -
Responses of Bugula neritina, an arborescent bryozoan to the removal of growing tips: short term patterns of regeneration.
In colonial organisms, physical damage or predation can result in the loss of part of the colony. Although the colony may survive, the loss of part of the colony may alter... -
Responses of Bugula neritina, an arborescent bryozoan, to the removal of growing tips at different locations within the colony
For colonial organisms physical damage or predation can result in the loss of part of the colony. Although the colony may survive, the loss of part of the colony may alter... -
Recovery of the encrusting bryozoan, Parasmittina delicatula, from damage at Queenscliff, Victoria.
Parasmittina delicatula colonies were located on the Queenscliff pier in early 1999 and assigned to a small size class (10-15mm) or large size class (30mm or more). Each colony... -
Patterns of recruitment of epifaunal species at Portsea, Victoria.
This study investigated the temporal and spatial patterns of recruitment of epifaunal species at Portsea. Recruitment panels were immersed at depths of 1 - 2.2 metres for 10... -
Patterns of establishment and subsequent change in the structure of a marine epifaunal community.
Artificial substrata were used to investigate the patterns of establishment and change in the structure of a subtidal, marine epifaunal community at Portsea, Victoria from... -
Patterns of development in the epifaunal community at Portsea, Victoria.
This experiment examined the temporal changes in species composition and diversity of a developing epifaunal community on artificial substrata at Portsea. The substrata used... -
Effects of sewage effluent on 'reference' infaunal assemblages.
This experiment tested the effects of secondary treated sewage effluent on infauna assemblages that were collected 2km from a sewage outfall ('reference' assemblage). Twelve... -
Effects of sewage effluent on 'pulse' infaunal assemblages.
This experiment tested the effects of secondary treated sewage effluent on infauna assemblages that were taken from a 'reference' site immediately after a large dump of... -
Effects of sewage effluent on 'outfall' infaunal assemblages.
This experiment tested the effects of secondary treated sewage effluent on infaunal assemblages that were collected 50m from a sewage outfall ('outfall' assemblage). Twelve... -
Effects of sewage effluent and shorebird exclusion on intertidal infaunal assemblages
This experiment tested the effects of liquid effluents on infauna assemblages in the presence and absence of shorebirds. Small plots of sediment (70cm x 50cm) were dosed with... -
Effects of Sabella spallanzanii physical structure on soft sediment macrofaunal assemblages: effects on colonisation
The introduced European polychaete Sabella spallanzanii has become a dominant feature of sub-tidal habitats in south-eastern Australia. This study examines the physical effects... -
Effects of Sabella spallanzanii physical structure on soft sediment macrofaunal assemblages: effects on existing assemblages
The introduced European polychaete Sabella spallanzani has become a dominant feature of sub-tidal habitats in south-eastern Australia. This study examines the physical effects... -
Effects of predation by fishes on the epifaunal community at Portsea, Victoria.
Exclusions were attached to artificial substrata to investigate the relative effects of predation on the development of epifaunal communities at Portsea. Exclusions were black... -
Effects of introduced species on the recruitment of sessile invertebrates.
This experiment was conducted to determine if an established Botryllus schlosseri colony affected the recruitment of sessile invertebrates. Small perspex plates that had been in... -
Effects of introduced sessile invertebrates: removal experiments.
Three removal experiments were conducted to test the effects of the introduced species, Bugula neritina, Ascidiella aspersa and Botryllus schlosseri on sessile invertebrate... -
Ecological effects of introduced sessile marine invertebrates.
Manipulative field experiments were used to investigate the effects of the ascidians Botryllus schlosseri and Ascidiella aspersa and the bryozoan Bugula neritina on sessile... -
Denitrification measurements of sediments using cores and chambers: comparison of fluxes and denitrification efficiencies
Denitrification is a microbial process that takes place on and within sediment and results in the transformation of dissolved inorganic nitrogen to nitrogen gas (N2), which is... -
Competitive interactions in the epifaunal community at Portsea, Victoria.
The resource provides information on the rates of growth, competitive ability and life spans of species in the epifaunal community at Portsea. Estimates of rates of growth for... -
Comparing the effects of an introduced and native species of bryozoan
An experiment was conducted to compare the effects of the introduced bryozoan, Bugula neritina, and the native bryozoan, Bugula dentata, on sessile invertebrate assemblages....
