Bino et al. 2015 Life history and dynamics of a platypus (Ornithorhynchus anatinus) population: four decades of mark-recapture surveys

Knowledge of the life-history and population dynamics of Australia’s iconic and evolutionarily distinct platypus (Ornithorhynchus anatinus) remains poor. We marked-recaptured 812 unique platypuses (total 1,622 captures), over four decades (1973–2014) in the Shoalhaven River, Australia. Strong sex-age differences were observed in life-history, including morphology and longevity. Apparent survival of adult females (Φ = 0.76) were higher than adult males (Φ = 0.57), as in juveniles: females Φ = 0.27, males Φ = 0.13. Females were highly likely to remain in the same pool (adult: P = 0.85, juvenile: P = 0.88), while residency rates were lower for males (adult: P = 0.74, juvenile: P = 0.46). We combined survival, movement and life-histories to develop population viability models and test the impact of a range of life-history parameters. While using estimated apparent survival produced unviable populations (mean population growth rate r = −0.23, extinction within 20 years), considering residency rates to adjust survival estimates, indicated more stable populations (r = 0.004, p = 0.04 of 100-year extinction). Further sensitivity analyses highlighted adult female survival and overall success of dispersal as most affecting viability. Findings provide robust life-history and viability estimates for a difficult study species. These could support developing large-scale population dynamics models required to underpin a much needed national risk assessment for the platypus, already declining in parts of its current distribution.

Brandis et al 2014 Assessing the use of camera traps to measure reproductive success in Straw-necked Ibis breeding colonies

Summary. Nest monitoring may influence reproductive success and rates of predation. This study compared data from two methods of monitoring nests — repeated visits to nests by investigators and collection of data by camera traps — in Straw-necked Ibis Threskiornis spinicollis breeding colonies in the Murrumbidgee catchment in New South Wales. There was no significant difference in reproductive success between nests monitored by these two methods. These data show that (1) nest monitoring using camera traps is a valid survey method that reduces the need for investigators to engage in intensive and costly monitoring in the field, and (2) there was no detectable interference from repeated visits to nests by investigators on the reproductive success of ibis.

Letten and Keith 2014 Phylogenetic and functional dissimilarity does not increase during temporal heathland succession

The compelling idea that closely related species should be less likely to coexist on account of their overlapping needs dates back to Darwin. It follows from Darwin's hypothesis that if species compete more intensely as communities mature, recently assembled communities (such as those emerging in the wake of a fire) will consist of closer relatives than older communities. Researchers from the Centre for Ecosystem Science tested this theory using a long-term dataset of community assembly in fire-prone heathland vegetation. Contrary to expectations, the relatedness of coexisting species tended to increase in the wake of fires, thus challenging this logical extention to one of ecology's oldest hypotheses.
