The existing literature on social exclusion among older people, though relatively limited, suggests that disadvantage among older people is cumulative in nature. Some aspects of disadvantage starting at early life stages have long-term consequences. As such, older people with disadvantages may be subject to higher risks of persistent social exclusion. This article aims to improve understanding of social exclusion and its persistence among senior Australians in three ways. Firstly, the incidence of social exclusion among older people is analysed using selected indicators. Secondly, the study examines whether an older person experiencing social exclusion at one time is more likely to experience it again (persistence). Thirdly, it investigates what factors may be protecting older people from social exclusion. The analysis is conducted using the first eight waves of the Household, Income and Labour Dynamics in Australia (HILDA) Survey. The sample of older people is disaggregated into a younger group (55–64 years at wave 1) and an older group (65+ years). The article suggests that higher education and income, as well as better health conditions and previous employment experiences, are important protective factors from social exclusion for older Australians.

This study investigated the boreal digging frog, Kaloula borealis, to determine the egg hatching period and whether the hatching period is affected by incubation temperature. The results of this study showed that all the eggs hatched within 48 h after spawning, with 28.1% (±10.8, n=52) hatching within 24 h and 99.9% (±0.23, n=49) within 48 h after spawning. A significant difference was noted in the mean hatching proportion of tadpoles at different water temperatures. The mean hatching rates between 15 and 24 h after spawning was higher at a water temperature of 21.1 (±0.2) °C than at 24.1 (±0.2) °C. These results suggest that incubation temperature affected the early life stages of the boreal digging frog, since they spawn in ponds or puddles that form during the rainy season.
