Application of infrared thermography coupled with Eulerian Video Magnification to monitor vital signs in wild seals, from sandy beaches to icy shores

In this study, we demonstrate that IRT-EVM is a powerful, non-invasive method for assessing vital signs in free-living pinnipeds. These imaging techniques are likely to be applicable towards study of other mammalian species, with appropriate validations for use in new field environments to ensure accuracy of IRT-EVM derived vital sign measurements is maintained. This work makes strides towards monitoring wildlife metabolic indices to evaluate impacts of intra-annual and longer-term environmental change on population health.
