LJMU's Research Centre in Evolutionary Anthropology and Palaeoecology actively engages with broadcasters and the creative sector, providing a significant evidence base and impacting the commissioning and content of television programming about human evolution. LJMU research is at the forefront of this activity, underpinning programmes that are an excellent vehicle to promote the public understanding of human evolution, which in turn promotes public engagement with science more generally. Television production companies and broadcasters approach LJMU to provide high-quality scientific input which drives decisions about and ultimately produces up-to-date factual programming that attracts, engages and educates large and diverse viewing audiences in the UK and worldwide.
Salmon maturation prior to harvest constitutes an environmental, welfare and production bottleneck for the salmon aquaculture industry. Our research has reduced the number of fish that mature during the grow-out phase so they do not reallocate energy to develop gonads and display secondary sexual characteristics that reduce yield, harvest quality and increase disease susceptibility that can result in downgrading at processing and lost profitability. In addition, reproductively competent fish that escape from on-growing cages may breed with wild stocks, leading to potential introgression. This has a major impact on public perception of farmed salmon and it limits the expansion of the industry. The IoA Reproduction team has undertaken a comprehensive body of work since 1993 to address this critical production bottleneck through an array of management strategies. This work culminated in the REF period by the demonstration that salmon puberty can be reduced to <3% by the use of standardised lighting regimes (2008) followed by the first commercial production of sterile salmon (2012-13).
Regulation of our sleep-wake cycle is crucial to health and well-being. The quality (intensity and spectral distribution) of artificial light is currently described according to its ability to activate rod and cone photoreceptors in the human eye. This approach ignores the discovery of a third photoreceptor that Lucas and his group have shown to be responsible for a range of sub-conscious neurophysiological and neurobehavioural responses to light, which together strongly contribute to health, productivity and well-being. Their research has established ways of measuring light that predict its effect on these newly discovered photoreceptors. They have partnered with industrial [text removed for publication] and public policy (various) organisations to translate this knowledge into improved artificial light sources and updated international standards for architectural lighting, for use in a wide range of domestic, public and industrial settings.
