Hacking","doi":"10.31646/WA.180","DOIUrl":"https://doi.org/10.31646/WA.180","url":null,"abstract":"This paper investigates possible changes in the organisation of the intertidal macrofauna community of Arrawarra Beach, NSW, over a range of tidal heights. The beach was divided into seven levels at low tide and 10 core samples for fauna were taken at each level during both high and low tide and at two evenly spaced tidal stages in between. For each tidal stage the distribution of the macrofauna across the shore was investigated for the existence of sub- communities across the tidal gradient using cluster analysis. This analysis failed to demonstrate a consistent “zonation” across the tidal cycle, although three sub-communities or assemblages were apparent high tide and the sample time before it. Movement of separate species populations was investigated over the tidal cycle using chi-squared analysis and an associated pseudo-probability test. Only one species (the polychaete Arabella iricolor iricolor) showed a significant change in distribution across the shore with time; however, small population numbers for many of the species may have confounded the concept of the potential movement with water level of sandy beach macrofauna as: i) a series of subcommunities; and ii) individual species. It is concluded that beach macrofaunal communities are organised as a seriation of species across the shore rather than in distinct “zones”.","PeriodicalId":197128,"journal":{"name":"Wetlands Australia Journal","volume":"28 16","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-01-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133424887","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}

Changes in mangrove/saltmarsh distribution in the Georges River estuary, southern Sydney, 1930-1970 1930-1970年悉尼南部乔治河河口红树林/盐沼分布的变化

Haworth","doi":"10.31646/WA.237","DOIUrl":"https://doi.org/10.31646/WA.237","url":null,"abstract":"Aerial photographs taken between 1930 and 1970 of the Georges River in southern Sydney show a rapid advance of mangroves landward (upslope) at the expense of salt-marsh, though the timing and extent of the advances was not the same in all locations. By 1970, in the central estuarine reaches, salt marsh has all but disappeared from the tidal wetlands of the bayhead fluvial-estuarine deltas, surviving only on the more open ‘half moon’ embayments adjacent to the main river, as well as on the Mill Creek delta. In contract, there was little or no advance of the mangroves seaward onto tidal mud flats during this period, except in the one instance of upper Salt Pan Creek, which also contains the highest proportion of erodible shale in its catchment. Salt marsh survived best in wetland sites with least disturbance from urban development and engineering works, strongly pointing to increased urban runoff and nutrient-enriched sediment as key factors accounting for local differences in mangrove advance. \u0000 \u0000The confined topography of bayhead sites produced the most complete and earliest changeover to mangroves, probably because they concentrated both runoff and nutrient in comparison to the more open sites near the main river. Mill Creek, with the least urbanised catchment, had areas that represented both geomorphic types, yet significant areas of salt marsh survived in all parts of the wetland. The general upslope advance of mangroves after 1940 in the Georges River is undoubtedly partly associated with the degree and timing of catchment disturbances as Sydney spread southwards. However, despite this local variability, the mid to late 20th Century mangrove advance both in the Georges River and elsewhere in southeast Australia is so widespread that the influence of other forcing agents, such as global sea level rise and regional changes in temperature and rainfall, cannot be ruled out.","PeriodicalId":197128,"journal":{"name":"Wetlands Australia Journal","volume":"22 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":"124113642","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}

Underwood","doi":"10.31646/WA.243","DOIUrl":"https://doi.org/10.31646/WA.243","url":null,"abstract":"Restoration of habitat is of increasing importance in the modern world as more of the remaining patches of natural habitats become degraded. Restoration is seen as an important way of reversing the trend. Although restoration is part of ecology and therefore could properly be considered a scientific discipline, scientific methodology and current ecological knowledge are missing from many restoration programmes. In Australia, much money and resources are wasted in on-the-ground projects which are poorly designed and seldom evaluated. There is a great need to bring a rigorous scientific protocol into programmes of restoration. Many programmes of restoration are poor because the logical connection between the aims of the programme and the means and assessment of restoration are lost. Here, we discuss the advantages of treating restoration as a test designed to falsify a null hypothesis within the scientific protocol used successfully in other branches of ecology. The aims of restoration, which are often expressed in rather general terms, usually include several steps in this protocol (the observations, models and hypotheses). Clearly separating these in logic is shown to lead to more realistic definitions and goals of restoration and more rigorous ways of assessing the success of these. Finally, we discuss recent advances in methodologies for detecting environmental impacts. These are potentially extremely useful for the measurement and evaluation of restoration, but they are not being incorporated into many programmes of restoration. Restoration must be treated as more of a scientific discipline if it is to progress and cease to be unaccountable.","PeriodicalId":197128,"journal":{"name":"Wetlands Australia Journal","volume":"6 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":"117353093","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}
