It is the only fucoid alga in the region which also exists in free-living populations, and in this is it comparable with the unattached saltmarsh fucoids occurring in the northern hemisphere. The unattached populations of Hormosira are most often associated with mangroves, and the characteristics of such plants have been described from New Zealand (moore 1950, Bergquist 1959) and south eastern Australia (Clarke and Womersley 1981, King 1981). \u0000 \u0000The population that grows amongst the pneumatophores in the Avicennia mangrove communities of southern Botany Bay, Australia, has been described by King (1981). It appears to have been derived from adjacent populations on rocky shores. The characteristics that distinguish the thalli from those of rocky shore populations include the lack of holdfasts, the absence of sexual reproduction, and the compact and highly branched thallus form. Other features regarded as characteristic of unattached fucoids include dwarfed and twisted thalli often with yellowish tips (Norton and Mathieson 1983). King (1981) noted that small thalli were common in the free-living Hormosira but also noted that someplants were about four times larger than those found on rocky shores.","PeriodicalId":197128,"journal":{"name":"Wetlands Australia Journal","volume":"51 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-02-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131313472","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Umitsu","doi":"10.31646/WA.232","DOIUrl":"https://doi.org/10.31646/WA.232","url":null,"abstract":"The Shoalhaven River is an example of a mature, infilled estuary on a wave-dominated coast. The river presently flows between prominent levees towards the coast, periodically exiting at Shoalhaven Heads, but having much of its flow artificially diverted to exit at Crookhaven Heads. The alluvial plains east of Nowra are the result of estuarine infilling behind a sand barrier, represented by Comerong Island, a southern continuation of the Seven Mile Beach beach-ridge plain. Drilli has revealed marine sands adjacent to this eastern sand barrier, and extensive muds deposited in a barrier estuary beneath most of the plains. The molluscan composition of these sediments indicates deposition in brackish water conditions, with Notospisula trigonella especially widespread. Estuarine infill occurred progressively around deltaic channels, isolating smaller basins which accreted subsequently. Most of the estuarine sedimentation occurred 5500 – 3500 radiocarbon years BP. Brackish-water muds grade upwards into fresh-water alluvial muds deposited from fluvial overbank flows, and the transition is indicated from analysis of the diatoms within sediments in an augerhole near Jaspers Brush. Levees overlie these estuarine sediments in places and indicate natural changes in river channel location. There is an extensive potential acid sulphate soil hazard throughout the plains as a result of the occurrence of pyrite-rich estuarine muds up to an elevation close to mean sea level beneath most of the plains.","PeriodicalId":197128,"journal":{"name":"Wetlands Australia Journal","volume":"39 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-02-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125434395","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Pollard","doi":"10.31646/WA.160","DOIUrl":"https://doi.org/10.31646/WA.160","url":null,"abstract":"The physico-chemical and hydrological characteristics of two intermittently opening coastal lagoons on the mid south coast of New South Wales were studied and compared with those of a permanently open coastal lagoon in the same area. Aspects studied over a period of several years during the mid to late 1980's included seasonal patterns of catchment rainfall, fluctuations in salinity and water temperature, and the opening regimes of these lagoons to the sea. The two intermittently opening lagoons (Swan Lake and Lake Wollumboola) were found to open for durations of around one to five months at approximately two-yearly intervals over the study period. Their salinity regimes fluctuated over this period in response to a complex of factors including rainfall and catchment runoff, temperature and surface evaporation, and the morphology of their entrance channels and duration of their opening to, and thus, the amount of water exchange with, the sea. These physical, chemical and hydrological characteristics are compared and contrasted with those of the permanently open lagoon (Lake Conjola), and also those of similar intermittently opening lagoons in other areas of the Indo-Pacific region (including south-western Australia, southern Africa and eastern Mexico). The above findings, and particularly those relating to lagoon opening regimes and salinity fluctuations, will be discussed in relation to both the community structure of fish assemblages and fisheries in these two types of lagoons, and juvenile fish recruitment to them and adult fish movements into and out of them, in subsequent papers describing the ecology of fishes in these systems.","PeriodicalId":197128,"journal":{"name":"Wetlands Australia Journal","volume":"91 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-01-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125897600","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This has reduced the amount of flooding in inland wetlands and reduced many of their ecological values. Difficult policy decisions are required to halt or reverse this degradation. We revise current policies and frameworks for decisions about management of river flows and inland wetlands in NSW. The commercial value of water for irrigation is often measured in terms of agricultural output, while the value of water for preserving wetland quality is described in ecological terms. In this paper we advocate the need for the correct valuation of the benefits of irrigation as well as the need to use environmental valuation techniques to estimate the monetary value of improved wetland quality when using an economic framework to assist in decisions about the management of river flows and inland wetlands. The paper reviews the use of revealed preference and stated preference techniques for estimating the monetary value of improved environmental quality, and provides examples of where these techniques have been used to value wetlands and river flows.","PeriodicalId":197128,"journal":{"name":"Wetlands Australia Journal","volume":"110 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-01-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134167832","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
