Drought and over-allocation of water have seen tree condition decline and environmental water is being used to aid recovery. An eight-variable visual assessment method is widely used to assess river red gum condition. These variables have been combined into a single aggregated index, the Red gum Condition Index (RCI), which comprises the Crown Condition sub-index (CCsi), which contributes 60% of the final score and assesses the amount of foliage in the tree crown; and the Secondary Variable sub-index (SVsi) which contributes 40% of the final score and aggregates measures of new tip growth, epicormic growth, reproduction, leaf die-off, mistletoe and bark condition. Relationships between variables define six condition categories. The R software package RCI calculates the RCI and provides quantitative and graphical outputs. Applied to two sites in South Australia, the RCI detected changes in tree condition attributable to environmental watering. As a responsive index with transparent categories the RCI can measure the current condition of river red gum stands and assess their watering needs. The RCI approach is readily transferrable to other tree species.","PeriodicalId":49425,"journal":{"name":"Transactions of the Royal Society of South Australia","volume":"30 1","pages":"67 - 85"},"PeriodicalIF":0.8,"publicationDate":"2019-01-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"85334973","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"综合性期刊","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This is particularly true with the loss of keystone species where considerable ecological shifts are anticipated. Strongly justified and well-managed translocations are increasingly employed in an attempt to mitigate the loss of species. Once widespread, Murray Crayfish Euastacas armatus is an iconic and keystone species that has suffered a considerable decline in distribution and abundance, including in the Lower River Murray where it is assumed to be rare or locally extinct. In the present study, we conducted targeted sampling at 30 sites from Lower River Murray over 2013–2017 to confirm its local extinction and then propose a strategy to reestablish the species, which defines a meaningful objective and monitoring indicators to assess reintroduction success, identifies suitable receiving habitats and source populations, defines reintroduction scenarios (e.g. numbers and duration) required (based on population modelling) and discussion limitations. Although first proposed a quarter of a century ago, we are now in an informed position to achieve this reintroduction objective. Considerable ecological and social benefits are anticipated with the successful reestablishment of a keystone species into the Lower River Murray.","PeriodicalId":49425,"journal":{"name":"Transactions of the Royal Society of South Australia","volume":"22 1","pages":"51 - 66"},"PeriodicalIF":0.8,"publicationDate":"2019-01-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"83922945","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"综合性期刊","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The vulnerable eastern Regent Parrot (Polytelis anthopeplus monarchoides) is declining in South Australia, but there is little information on the behavioural ecology of its cavity-nesting habits. The aim of this study was to quantify parental nest visitation behaviour and measure nest site attributes in relation to nesting outcome. We collected data from 25 nests along the Murray River in South Australia, and analysed 608 h of video recording and 67 h of binocular observations. This study provides the first quantitative data on parental care behaviour of the eastern Regent Parrot. The results show (1) parent birds had ~0.5 visits per hour during incubation and ~2 visits per hour during feeding; (2) 16% of nesting cavities were abandoned, 24% usurped, 4% depredated (by lace monitor, Varanus varius), 4% unknown outcome; and (3) canopy cover was 58% at successful nests versus 34% at failed nests. Behavioural monitoring in the field should span at least two hours to capture parental activity at the nest, nesting success was correlated with canopy cover, and nesting failure was mostly explained by usurpation and abandonment.","PeriodicalId":49425,"journal":{"name":"Transactions of the Royal Society of South Australia","volume":"4 1","pages":"147 - 165"},"PeriodicalIF":0.8,"publicationDate":"2018-12-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1080/03721426.2018.1552825","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"72503743","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"综合性期刊","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Filling the wetland with freshwater lowered electrical conductivity (EC) from ~60 to 13 dS m–1. This freshening was accompanied by substantial declines in total P (TP), filterable reactive P (FRP), dissolved organic C (DOC), total organic N (TON), dissolved organic N (DON), NH4+ and molybdenum-reactive Si (MoR Si) concentrations. Owing to the semiarid climate, the water level receded and EC increased to pre-flooding conditions within seven months. During this drying phase, some chemical species maintained lower concentrations then pre-flooding (TP and FRP), others returned to within their original range (DOC, TON, DON), and others went above their original range (NH4+ and MoR Si), the latter reflecting some bank discharge of groundwater. Unexpectedly low turbidity and P concentrations during the drying phase were promoted by the development of an extensive filamentous algal mat following flooding, which limited sediment resuspension as the water level receded. The transient response to freshening highlights that salinity is a key driver of biogeochemical cycles in semi-arid wetlands.","PeriodicalId":49425,"journal":{"name":"Transactions of the Royal Society of South Australia","volume":"7 1","pages":"27 - 50"},"PeriodicalIF":0.8,"publicationDate":"2018-11-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"91263667","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"综合性期刊","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This makes these production systems vulnerable to ecological disturbances. Quantifying the densities of feral honey bees is key to determining the reliance of free pollination services and system vulnerability. Current methods for estimating densities of feral honey bee hives are based on the number of haplotypes identified from drones caught using a pheromone lure. This method assumes that all hives contribute to the drone population, and that the area over which they are attracted is known. To test these assumptions the estimates based on drone capture should be compared to the genetic composition of hives in the same area. We developed a flag and pole method to sample worker sting DNA from feral hives in trees. We show that the use of alarm pheromone isopentyl acetate can significantly increase the efficiency of this method. We also demonstrate that the DNA collected from sting samples will amplify via PCR to a band intensity similar to that of leg tissue. In addition to providing a method to verify hive density estimates based on drone captures other applications of our method are discussed.","PeriodicalId":49425,"journal":{"name":"Transactions of the Royal Society of South Australia","volume":"75 1","pages":"92 - 96"},"PeriodicalIF":0.8,"publicationDate":"2018-11-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"85966478","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"综合性期刊","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
