Biomarkers to Assess Possible Biological Effects on Reproductive Potential, Immune Function, and Energetic Fitness of Bottlenose Dolphins Exposed to Sounds Consistent with Naval Sonars
Abstract
The overarching goal of this research is to utilize novel biomarkers to examine whether significant sub-lethal responses to sonar-type sounds occur in bottlenose dolphins exposed to such sounds. The collaborators will use immune function markers, acute phase proteins, fertility potential assays, and targeted and non-targeted metabolomics to investigate samples collected from trained dolphins before exposure to the sonar-type sounds, immediately after exposure, and one week post-exposure. Today's molecular technologies, in the form of biomarkers, provide avenues by which scientists can directly measure biologically significant responses such as changes in reproductive potential, immune system function, acute phase responses, and energetic fitness. The objectives of our collaborative study were as follows: (1) acquire appropriate samples for analysis, (2) conduct R&D to ensure that available assays can measure useful parameters, (3) design experiments in which animals are humanely exposed to stressors and in which an extensive suite of biological effects are monitored, (4) conduct chemical assays that rigorously adhere to QA/QC requirements, and (5) interpret the results of the assays with regard to what they do or do not do in terms of biologically significant effects on individuals and populations.
