Cerberiopsis candelabra Vieill. is a long-lived, monocarpic (= semelparous) and mass-flowering rain-forest tree, endemic to New Caledonia. Population size structures suggest establishment has been episodic, followed by a recruitment gap that might signal population decline. Here, we use age structures based on tree rings to better assess population dynamics and persistence, and investigate influences of tree size, age and growth rate on flowering. Age structures of populations surveyed in 2007–2008 were unimodal, with establishment over c. 15–81 y, followed by a recruitment gap of c. 23–79 y. Seedling mortality was generally high. High densities of flowering trees or large-scale exogenous disturbances may be necessary for in-situ regeneration. There was no evidence of a simple flowering threshold: flowering in 2017 occurred across a wide range of tree size, age and growth rate. Instead, evidence suggested that size and age at flowering may vary among plants depending on their growth trajectory. Environmental triggers of flowering were not identified by dating tree establishment, but the last three mass-flowering events occurred in years of tropical cyclones. Regeneration and persistence might be facilitated if large-scale disturbances trigger flowering, improving reproductive efficiency by synchronising flowering and linking reproduction with environmental conditions that enhance seedling recruitment.

John Carne Bidwill was born in 1815 in England and died in Queensland in 1853. His short life is relevant to Australia's garden history, botany, the horticultural use of Australian plants in European gardens and the colonial history of Sydney, New Zealand, Wide Bay and Maryborough. He may have been the first to introduce plant breeding into Australia. In a short life, and working in his spare time, he contributed more than many full-time and longer-lived horticulturists. This included discovering new species, crossing new hybrids (specific and inter-generic), and propagating and promulgating plants for the nursery trade and gardeners. His efforts are marked by his name gracing many Australian and New Zealand plants, exotic plant hybrids and modern suburbs of Sydney and Maryborough. This brief biography outlines Bidwill's time in Australasia and Queensland.

Primiparae were randomly assigned to two conditions of routine ultrasound examination at their first antenatal clinic visit: (a) high feedback ultrasound where the monitor screen was visible and the patient was shown the foetal size, shape and movement (N = 67); (b) low feedback ultrasound where the screen was not seen and specific verbal feedback was denied (N = 62). Women were interviewed at 16 weeks gestation. Those receiving high feedback were more likely to report that they had acted on health advice given at the first antenatal visit to reduce their smoking and drinking.
