Project Title: Impacts of substrate-borne vibration and chemical stressors on the embryonic development and hatching of marine invertebrates

Abstract:

Emerging evidence is highlighting the importance of sensory cues in the regulation of embryonic development and hatching for many species. Multiple environmental stressors, such as substrate-borne vibration and chemical pollution from anthropogenic activities, could therefore influence hatching times and disrupt developmental processes. Water-borne noise has been shown to decrease hatching success in marine invertebrates, as well as alter hatching times and developmental rates. However, the potential impacts of substrate-borne vibration, both as a single stressor and in combination with chemical stressors, on the embryonic development and hatching of marine invertebrates is largely unknown. Investigating embryonic and larval stages of species is crucial to develop a population level understanding of how multiple stressors potentially impact marine invertebrates, and therefore marine ecosystems. Results will be informative for future conservation management strategies and aid in the development of mitigation measures for anthropogenic activities relating to the seabed.
