Project description
A new way to assess physiological state in wild animals
Fitness – the ability of an organism to survive and reproduce – is central to evolutionary biology and conservation ecology. Thermal imaging of body surface temperature has been proposed as a non-invasive means to examine how physiological processes in wild animals are dynamically adjusted to maximise fitness in response to environmental variation. The aim of the EU-funded THERMALIMAGING STATE project is to develop thermal imaging as a powerful new tool to advance our understanding of the links between individual state and fitness in natural environments. This novel technique will be validated in the US and then field-trialled in the EU, guided by the expertise of internationally recognised ecophysiologists at the University of Groningen and the Max Planck Institute for Ornithology.
Objective
Understanding variation in ability to survive and pass on genes (fitness) is central to evolutionary biology and conservation ecology. Fitness differences are largely explained by physiological state, as physiological processes are dynamically adjusted to maximise fitness in response to environmental variation. However, assessing physiological state in wild animals is usually invasive, requiring trapping and handling. As well as raising ethical concerns, such techniques interrupt natural behaviour, can cause bias toward trappable individuals, and may alter subsequent performance. Welfare limits on repeated invasive sampling also restrict tracking of responses over time. Previously, I provided proof of concept for an innovative alternative approach to overcome these issues non-invasive thermal imaging of body surface temperature. I showed body surface temperature reflects two physiological processes highly relevant to fitness acute stress and maintenance of energy reserves. But, the mechanisms underlying these relationships remain unclear, calling for rigorous experimental exploration to build the foundations needed for this method to be applied in research and conservation. Hence, the aim of this proposal is to develop thermal imaging as a powerful new tool to advance understanding of the links between individual state and fitness in natural environments. An initial visit to the world leading wild-vertebrate stress lab (Tufts University, US) will be used to perform detailed physiological validations in captivity. Methods established in the US will then be field-trialled in the EU, guided by the expertise of internationally recognised ecophysiologists at the University of Groningen and Max Planck Institute for Ornithology, ensuring in-depth synthesis of results. Combined, this work will place me at the forefront of the exciting, transformative use of thermal imaging as a novel tool for studying how wild animals cope with changing environments.
