Observations were made on the behaviour of a group of slender lorises (Loris tαrdigrαdus) maintained in the Adelaide Zoo. Descriptions of their individual behaviour, social interactions, reproductive biology and development of young are given. The slender loris displays a more complex social lifestyle than has previously been reported, with huddling, marking activities and the behavioural complex of stretching/wrestling/allogrooming occurring daily. Evidence of the formation of a female coalition is described for the first time for this species. The low reproductive success of the group may have been attributable to the mixing of two Sri Lanka subspecies. Matings between L. tαrdigrαdus grαndis and L. tαrdigrαdus tαrdigrαdus produced one sibling that reached maturity but did not breed.

hydrological models to estimate concentrations of pharmaceutical and natural steroid estrogens in a 20 water stressed catchment in South Australia alongside a UK catchment and to forecast their 21 concentrations in 2050 based on demographic and climate change predictions. The results show that 22 despite their differing climates and demographics, modeled concentrations of steroid estrogens in 23 effluents from Australian sewage treatment works and a receiving river were predicted (simulated) to be 24 similar to those observed in the UK and Europe, exceeding the combined estradiol equivalent's 25 predicted no effect concentration for feminization in wild fish. Furthermore, by 2050 a moderate 26 increase in estrogenic contamination and the potential risk to wildlife was predicted with up to a two-27 fold rise in concentrations. 28
