The last decade has witnessed exciting developments in multi-target tracking theory and practice. Mahler's finite set statistics (FISST) provides a general systematic foundation for multi-target tracking based on the theory of random finite set (RFS). The RFS framework has led to the development of novel and efficient multi-target Bayes filters and their(More)
Assessment of plastic and heritable components of phenotypic variation is crucial for understanding the evolution of adaptive character traits in heterogeneous environments. We assessed the above in relation to adaptive shell morphology of the rocky intertidal snail Nucella lapillus by reciprocal transplantation of snails between two shores differing in(More)
The bryozoan Celleporella has been shown to be composed of multiple, often cryptic, lineages. We sequenced two complete mitochondrial (mt) genomes of the Celleporella hyalina species complex from Wales, UK and Norway (i) to determine genetic divergence at the complete mt genome level, and (ii) to design new molecular markers for examining the(More)
Natural variability in stable isotope ratios and element concentrations in calcified structures of fish (e.g. scales and otoliths) has provided biogeochemical ‘tags’ for studying origins and movements of marine species, but has been little used in freshwater studies. We examine whether variability in scale δ15N and δ13C values of Salmo trutta L., could(More)
ACKNOWLEDGEMENTS This framework paper has been prepared by Dr. Roger Hughes (School of Public Health, Griffith University) with input from members of the Australian Public Health Nutrition Academic Collaboration (APHNAC) and others, listed below. This competency framework is presented in response to the Public Health Education and Research Program (PHERP)(More)
Polyembryony-the production of multiple cloned embryos from a single fertilised egg-is a seemingly paradoxical combination of reproductive modes that nevertheless persists in diverse taxa. We document features of polyembryony in the Cyclostomata (Bryozoa)-an ancient order of modular colonial marine invertebrates-that suggest a substantial reduction in the(More)
The Sendai Framework for Disaster Risk Reduction (2015) is a global strategy for addressing disaster risk and resilience that has been ratified by member countries of the United Nations. Its guiding principles emphasise building resilience through inter-sectoral collaboration, as well as partnerships that facilitate community empowerment and address(More)
The intertidal snail Nucella lapillus generally has thicker shells at sites sheltered from wave action, where crabs are abundant and pose a high risk of predation, than at exposed sites where crabs are rare. We studied two populations showing the opposite trend. We reciprocally transplanted snails between field sites and measured shell length, width and lip(More)
When a steamroller is coming down the road, you have three choices: Get out of the way, run to stay ahead of it, or lie down and get your clothes pressed. The steamroller is age — old age — and it will remake our society in the first half of the 21st century. Everything from census numbers to personal experiences underscores the aging of our state and(More)
