Topic: Blow, Baleen, and Dentine: Alternative matrices for studying the physiology of marine mammals
Arctic marine mammals are experiencing a number of threats, including climate change and increased anthropogenic activity. These threats have the potential to alter the physiological state of individuals (e.g. increased stress levels due to environmental pressures or suboptimal shifts in diet), which could lead to population-level consequences over time. Physiological tools, such as measuring steroid hormones, can be useful in assessing the impacts of these threats; however, collecting samples from marine mammals can be challenging and novel tools are needed. Here, we explore the use of three alternative matrices, blow, baleen, and dentine, to assess the physiological state of Arctic marine mammals to better understand their life histories and the potential impacts of climate change and human activity.
