This personal narrative tracks the history of this epidemic in Tasmania during the 1960s, when it first appeared as iodine deficiency, then as iodine excess, how it was formally recognised and the events leading to its eventual treatment. The addition of iodine into the diet of Tasmanians, initially in bread and then unwittingly through use of iodophors in the dairy industry, resulted in a sequence of events that required unravelling by medical practitioners new to the field but aided by experts from elsewhere. The Tasmanian thyrotoxicosis epidemic was, and continues to be, cited in the annals of the scientific literature as an important medical case study.","PeriodicalId":35513,"journal":{"name":"Papers and Proceedings - Royal Society of Tasmania","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2021-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"69101999","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}

A range of threats occur across all species, with four listed as endangered, two as critically endangered, and the Red Handfish now on the brink of extinction. This paper summarises the contribution being made to the national recovery of the Spotted Handfish and Red Handfish by a captive breeding project underway at Beauty Point in northern Tasmania. Information is provided on husbandry techniques, survival and growth rates in captivity and a trial underway to identify their reproductive strategies. This program highlights the contribution the aquarium industry can make to improving the survival of two of the world’s most unique species of marine fishes and the collaboratives efforts of those involved.","PeriodicalId":35513,"journal":{"name":"Papers and Proceedings - Royal Society of Tasmania","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2021-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"69102015","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}

A nesting aggregation of females was observed over a 25-day period, enabling the first detailed observations of host log, nest design, prey and egg deposition, and behavioural patterns to be made. Cells were provisioned with large flies (order Diptera) of nine species from nine genera and four families to observe behaviour. This aggregation used a large eucalypt with an exposed core of friable brown rot for nesting. Our study showed that the day-to-day behaviour of the female is predictable, centring on nest construction, hunting large flies and egg-laying.

The resulting narrow trough, some 50 km long and 5 km wide, has been partially infilled with soft sands, clays and gravels, with intercalated basalt flows in places, of mainly Paleogene (lower Tertiary) age. Low hills of hard Jurassic dolerite define the structure on either side. The graben was formed during the break-up of Gondwana, the separation of Australia from Antarctica, and the making of Tasmania, in the Cretaceous-early Cenozoic period, some 70–140 million years ago (Ma). A spreading ridge had propagated eastwards through the Great Australian Bight but was unable to break through the Bass Strait area, and instead a large wedge of crust containing the future Tasmania was pulled away from the corner of Antarctica on a series of transcurrent faults. The associated crustal stretching in the Bass Strait area resulted in the formation of the deep ‘hole’ of Bass Basin, which had offshoots onto what became Tasmania, including the Tamar Graben. For much of its life, the Tamar River was a major feeder stream into the Bass Basin, carrying large volumes of sediment eroded from the Tasmanian highlands. The course of its major tributary, the South Esk River, within the southern part of the graben was completely blocked by basalt flows near the present Evandale about 35 Ma, forcing it into a new course to the west through the dolerite, to form the Cataract Gorge.","PeriodicalId":35513,"journal":{"name":"Papers and Proceedings - Royal Society of Tasmania","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2021-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"69101985","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}
