Haematological and biochemical reference intervals for wild green turtles (Chelonia mydas): a Bayesian approach for small sample sizes

Animal health is directly linked to population viability, which may be impacted by anthropogenic disturbances and diseases. Reference intervals (RIs) for haematology and blood biochemistry are essential tools for the assessment of animal health. However, establishing and interpreting robust RIs for threatened species is often challenged by small sample sizes. Bayesian predictive modelling is well suited to sample size limitations, accounting for individual variation and interactions between influencing variables. We aimed to derive baseline RIs for green turtles (Chelonia mydas) across two foraging aggregations in North Queensland, Australia, using Bayesian generalized linear mixed-effects models (n=97). The predicted RIs were contained within previously published values and had narrower credible intervals. Most analytes did not vary significantly with foraging ground (76%, 22/29), body mass (86%, 25/29) or curved carapace length (83%, 24/29). Length and body mass effects were found for eosinophils, heterophil:lymphocyte ratio, alkaline phosphatase, aspartate transaminase and urea. Significant differences between foraging grounds were found for albumin, cholesterol, potassium, total protein, triglycerides, uric acid and calcium:phosphorus ratio. We provide derived RIs for foraging green turtles, which will be helpful in future population health assessments and conservation efforts. Future RI studies on threatened species would benefit from adapting established veterinary and biomedical standards

Diversifying audiences and producers of public involvement in scientific research:The AudioLab

Plain English summary A partnership between a public engagement specialist, and a director of a digital radio station working towards social change, The AudioLab is a creative and innovative way to support diverse young people to connect with and get actively involved in health research. We worked with 25 creative young adults at relative socioeconomic, educational and/or health disadvantage in 2016 and 2017. Facilitated by the project leads, the emerging young talents connected with science in a series of culturally- and personally-relevant and creative sessions, culminating in their production of digital content and a one-hour live radio show, which reached at least 2324 people online. As a result of taking part in The AudioLab, the young adults felt more confident about themselves and about science; they could see a role for their creative talents in science communication, and felt able to become actively involved in health research. After the project, the ongoing partnership between the project leads and the young adults helped 12 of the participants to progress to employment, training and voluntary roles within health, research, creative and communications environments. We believe that the AudioLab presents a way of working that takes a step towards greater diversity and inclusion among both the audiences and producers of public involvement in health research. It has the potential to be reproduced as a method in other locations. Abstract Background The AudioLab is an innovative way to support greater inclusion in public engagement and involvement in health research. A partnership between a public engagement with research specialist, and a director of a digital radio station working towards social change, The AudioLab piloted an approach working with young people at relative socioeconomic, educational and/or health disadvantage to engage and involve them meaningfully, and sustainably, with health science and research. Methods Twenty-five young adults from diverse backgrounds took part in AudioLab pilots in 2016 and 2017. Facilitated by the project leads, they engaged with science in a series of culturally-relevant and creative sessions, culminating in their production of digital content and a one-hour live radio show, the latter reaching at least 2324 people online. Results Young adults’ agency within health research and science engagement was increased, with 12 of the participants progressing to roles within health, research, creative and communications environments. Conclusions Through partnership working between the project leads, co-production of creative outputs by the young people with scientists and science communicators, and a ‘reimagining’ of the positive assets that diverse young adults bring to engagement with health research, the AudioLab presents a way of working that takes a step towards greater diversity and inclusion among both the audiences and producers of public involvement in health research. Further, the AudioLab has the potential to be reproduced as a method in other locations
