150 years of democracy? The case of New South Wales

New South Wales has a rich history of parliamentary democracy. As the oldest of the Australian States, it has provided a microcosm of the evolution of modern British-style democracy from the ‘hustings’ of the early colonial to the harbour views of the contemporary politicians’ offices. New South Wales’ political history is also rich with experimentation. The early introduction of the secret ballot, payment for members, the abolition of plural voting, and adult suffrage are well known. Although it needs to be recognized that it followed slightly behind that ‘ Paradise of Dissent’ South Australia on all those features.

Equally fascinating is the role of the Labour Party, whose campaigning on behalf of adult suffrage and payment for Members is fairly well known. Less known, but of great interest, were its activities on behalf of electoral reform, political accountability and easier enrolment and voting, particularly for ‘ itinerants’ at a time when its political base was in the rural workforce. New South Wales Labour was significant for its decision to stand alone, in contrast with its Victorian and New Zealand counterparts, which threw in their lot with the Progressives.

Climate change and sea turtles : a 150-year reconstruction of incubation temperatures at a major marine turtle rookery

Sea turtles show temperature dependent sex determination. Using an empirical relationship between sand and air temperature, we reconstructed the nest temperatures since 1855 at Ascension Island, a major green turtle (Chelonia mydas) rookery. Our results show that inter-beach thermal variations, previously ascribed to the albedo of the sand, which varies hugely from one beach to another, have persisted for the last century. Reconstructed nest temperatures varied by only 0.5 °C on individual beaches over the course of the nesting season, while the temperature difference between two key nesting beaches was always around 3 °C. Hence inter-beach thermal variations are the main factor causing a large range of incubation temperatures at this rookery. There was a general warming trend for nests, with a mean increase in reconstructed nest temperatures for different months of between 0.36 and 0.49 °C for the last 100 years.
