N.A.Wakef., a distinctive plant restricted to northeast Tasmania. It compares changes over time in population size and evaluates the species response to disturbance. Results found H. calycina distribution is restricted to isolated clumps on highly insolated ridges and steep upper slopes of fine-grained Mathinna-series sedimentary rocks in dry sclerophyll forest dominated by Eucalyptus sieberi L.Johnson. Nine populations were documented with an estimated area of occupancy of 0.43 km2 and area of extent measuring 95 km2, demonstrating that the current listing of H. calycina as vulnerable is appropriate on Tasmania’s Threatened Species Protection Act 1995. We believe that the distribution of the present population is a result of natural factors (i.e., restricted habitat range and natural fire events) and anthropogenic factors (managed fire regime and illegal firewood cutting). Although frequent fire and roading have the potential to impact populations, H. calycina appears to be stable without active management in a landscape of patchy, regular, low severity fire. Our results indicate susceptibility to the soil-borne pathogen Phytophthora cinnamomi is likely less problematic than previously postulated, yet more data and research is required before management is changed.","PeriodicalId":35513,"journal":{"name":"Papers and Proceedings - Royal Society of Tasmania","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2020-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"69102247","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 paper examines the presence and behaviour of insect and bird visitors as potential pollen vectors. Very few insects were observed to visit the flowers. However, several bird species fed on the flower-heads and foraged for small invertebrates inhabiting the blossoms. These feeding behaviours resulted in adhesion of pollen to feathers likely to be transferred from one genet to another as birds moved. During feeding, rosellas were observed to not only ingest flower-heads but the presence of branchlet clip under 57% of A. dealbata trees surveyed is evidence of the widespread occurrence of these species foraging on flowers. However, given the profusion of flowers and the small numbers of birds observed, it is difficult to conclude that birds are wholly responsible for outcross pollination and we discuss the possibility that wind may also be an important pollen vector. Although the floral attributes of A. dealbata are more aligned with insect pollination, we failed to definitively identify any one major pollinator of the species in this environment and suggest that the pollination syndrome may most accurately be described as generalist.","PeriodicalId":35513,"journal":{"name":"Papers and Proceedings - Royal Society of Tasmania","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2020-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"69102312","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}

It is important for heritage management to understand the scenic attractors of tourists. Photographs of Cradle Mountain (150) and Freycinet National Park (149) were collected from a range of sources to determine whether there is a constancy of gaze between those who promote tourism and those who tour, and between the two visually distinct destinations. Publicly available images from four different sources were used to compare content attributes and mise en scene attributes between localities using Chi-square and ANOSIM. The photographs were then ordinated using the same attributes, and the results were displayed using photographic average composites. The Discover Tasmania and Google Images photographs were similar, both better conforming to advanced compositional principles compared to the Instagram and promotional images, which were similar, especially in the featuring of people in landscape foregrounds. There may be a reciprocal interaction between promotional and tourist images, rather than a one-way process. The contrasting features in the images from the two places were largely a product of the very different physical environments. However, the photographs at Freycinet were taken from several geographic locations, whereas the vista of Dove Lake and Cradle Mountain dominated all image sources at Cradle Mountain. The content analysis of the images was consistent between places, except where a feature of an artefact or natural feature created opportunity for artistic expression.","PeriodicalId":35513,"journal":{"name":"Papers and Proceedings - Royal Society of Tasmania","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2020-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"69102143","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}

In cases of suspicious death of humans and animals, carrion insects may be used to assist in crime scene reconstruction. The present research represents the first study in forensic entomology to be undertaken in Tasmania, investigating insect succession patterns on decomposing pig carcasses and providing a preliminary database of forensically important insects. Six pig carcasses were placed in two contrasting locations (rural and urban) in northern Tasmania. Insect successional waves were recorded over a 40-day study during the austral summer season. Results showed that decomposition rates and insect assemblages varied between each location. Eleven insect taxa, representing nine families, were identified in association with the decomposition of the pig carcasses at both localities. Blowflies present on the pig carcasses throughout the decomposition process were Calliphora stygia Malloch (Diptera: Calliphoridae) at both sites and Lucilia sericata (Meigen) at the urban site only. These preliminary results will provide useful information in any future casework involving human remains and associated insect material in Tasmania.","PeriodicalId":35513,"journal":{"name":"Papers and Proceedings - Royal Society of Tasmania","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2019-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"69102088","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}

For our study of the effect of edaphic factors on vegetation we chose Long Point in Moulting Lagoon, Tasmania’s largest saltmarsh, which is dominated by a diverse assemblage of halophytic succulents and graminoids. Three transects were established to sample variations in vegetation along the gradient from saltmarsh to woodland. Soil samples were analysed for summer and winter moisture, pH, and electrical conductivity (EC); a mixed summer and winter sample from each point was analysed for soil organic matter (SOM) and carbon. Additionally, a particle size analysis was carried out on all summer samples. Aspects of soil characteristics were aligned to classified vegetation groups and elevation. Moisture, pH, EC, SOM and carbon were all negatively correlated with elevation; the saltmarsh zone displaying higher levels of all variables than those in the adjacent woodland zone. Clay content decreased and sand content increased from the marine margin of the saltmarsh zone to the woodland zone. Within the saltmarsh zone, soil moisture, EC and carbon had highest values in the low marsh area, with values decreasing towards the upper marsh area. This study deepens our understanding of the roles various edaphic factors play in the floristic composition of coastal saltmarshes.","PeriodicalId":35513,"journal":{"name":"Papers and Proceedings - Royal Society of Tasmania","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2019-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"69102126","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}
