The 17 production of the adhesive secretions was monitored using microscopy and staining 18 experiments, while the attachment strength over substrates of varied chemistry and 19 topography was indirectly evaluated through flow channel experiments. Branched chains of beads (vesicles) varying in shape from round to oval depending on habitat. Subregnum: Harosa The swimming behaviour of Hormosira banksii spermatozoids was studied using videomicroscopy under different conditions, including movement on glass surfaces, on solvent droplets containing the species-specific gamete attractant at different concentrations and in relation to eggs. General Description. Hormosira banksii is a relatively large brown alga, which occupies the lower intertidal rocky platforms of southern Australasia.

Summary 5 Hormosira banksii (known as Neptune's necklace, Neptune's pearls, sea grapes or bubbleweed) is a species of seaweed (brown algae, Fucales) found in Australia and New Zealand.It is commonly found in rock pools at mid-tide levels and is characterised by strings of olive-brown hollow beads. Providers NIWA NZIB Provider Contribution Summary Biostatus The intertidal seaweed Hormosira banksii (H. banksii) is an abundant species and important ecosystem engineer on rocky shores and estuaries in south-east Australia, where it creates thick canopies colonized by a range of invertebrates, particularly gastropods.

Classification. NVS code Help. Abstract Hormosira banksii is an important intertidal habitat-forming seaweed in southern Australia that shows large variation in morphology. Research focussing on the roles of ecosystem engineers is lagging behind restoration research of ecosystem engineers. On a shallow sand flat at Princess Royal Harbour near Albany, Western Australia, the brown macrophyte Hormosira banksii attaches to shells of infaunal bivalves. The thallus consists of branched chains of water-filled vesicles (or receptacles), spherical to elongate in shape (Womersley 1987), but the morphology is very variable. Some infaunal bivalves do serve as anchors for holdfasts of macroalgae, like Katelysia rhinophera hosting Hormosira banksii in Princess Royal Harbor, Western Australia (Black and Peterson, 1987), and such macroalgal growth is habitat for many smaller crustaceans and fish. H. banksii is the most broadly distributed brown macroalga in Australasia, with the edge of its equatorward distributional limit located at a cold-warm transition zone (∼28 °S). Selected citations: Clarke & Womersley 1981: 497, figs 1–3. This study is by far the largest quantitative evaluation of morphological variation in H. banksii.

WildNet taxon ID Notheia anomala is a macroalgae in the family Notheiceae and the order Fucales.It is native to New Zealand and Australia.It is an obligate epiphyte that is commonly found growing on Hormosira (although there is a single unconfirmed observation of Notheia being attached to Xiphophora chondrophylla). Superregnum: Eukaryota Provide feedback or report problems to Infraphylum: Limnista Hormosira banksii(Turner) Decaisne is a brown macro- alga common to southeastern and southern Australia. Based on an experimental design developed by Toxikos Pty Ltd, Gunns Limited requested that the 72-h germination assay with H. banksii be extended to assess rhizoid growth over a 14 and 21-day exposure period, which may prove to be more We review the role of benthic macroalgae as ecosystem engineers and focus particularly on the temperate Australasian fucoid Hormosira banksii as a case study for rocky intertidal restoration efforts. Infraregnum: Heterokonta Abstract. We investigated the effects of phosphate, ammonium, and a mixture of heavy metals as components of sewage effluent, together with the effects of reduced salinity due to sewage effluent discharge into a marine environment, on the development of Hormosira banksii (Turner) Decaisne embryos. • interactions among Hormosira banksii, Morula marginalba (drilling, carnivorous gastropod), barnacles •Morula refuges within the wet canopy of Hormosira at low tide • Barnacle mortality high within near seaweeds • storm in 1974, tore Hormosira away, no cover for Morula • … Laboratory proce-dures for obtaining gamete release, fertilization, and Author information: (1)Institute for Marine and Antarctic Studies, University of Tasmania, Private Bag 1370, Launceston, Tasmania, 7250, Australia. Hormosira banksii is a dominant intertidal alga characterised by limited dispersal of propagules, yet it has a broad distribution throughout temperate Australasia. Several simple or branched stalks can arise from a simple disc-like holdfast. Hormosira banksii is a morphologically variable macro-algal species from southeastern and southern Australia, which has been previously categorised into ecoforms according to habitat. The beads have a slimy layer which conserves moisture. Flora category. How satisfied are you with your experience today? Both plants are light-tolerating and tolerant of some admixture of fresh water and mud, but Corallina can grow exposed to the strongest surf where Hormosira cannot exist. McKenzie, A.
