Anthropogenic Sound and Bivalve Behavior

Full Title: Impacts of Anthropogenic Sound on Bivalve Behavior
In response to growing concerns about anthropogenic sound’s impact on marine organisms, particularly in aquaculture settings, this project aims to investigate its effects on bivalve behavior and physiology across different life stages. With limited understanding of how laboratory and coastal sounds influence bivalve activities and ecosystem services provision.

Project Abstract:

There has been an increased interest in the impact of anthropogenic sound on marine organisms in coastal systems and in aquaculture in recent years. Bivalve hatcheries and nurseries in Florida frequently experience difficulties producing seed. One parameter we have not considered as a potential culprit is sound. Further, adult bivalves are becoming increasingly valued in Florida for their ecosystem services. In laboratory measurements, we have observed that ambient and equipment sounds effect the valve-gaping behavior of bivalves. Little is known about the effects of laboratory and common coastal sounds on behavior, filtration rates, and provision of ecosystem services. This project will support an undergraduate intern, with the overall goal of experimentally examining the effects of anthropogenic sound on the behavior and physiology of important bivalve species at three life stages.

No cost extension was granted through 12/31/24 due to several issues: 1) funds were not available for expenditures until late May, 2023. 2) The student intern could not immediately find local summer housing, delaying his starting work in the lab until late June. 3) Many of the electrical supplies needed were on backorder and/or were delayed in arriving, possibly due to continuing Covid shortages. 4) The PI had health issues from mid-May to mid-November, necessitating considerable sick leave. This unfairly delayed the student intern in his work since the PI was not available for guidance on a full-time basis.

This proposal outlines a collaborative effort between Florida Sea Grant (FSG) and the University of Florida’s Shimberg Center for Housing Studies to develop a statewide resiliency initiative called “Disaster Resilient Florida,” aimed at addressing coastal climate change challenges with a focus on underserved communities. The initiative will advance awareness, planning, and preparation for the impacts of coastal climate change on affordable housing in Florida, through capacity building, educational opportunities, partnership expansion, and support for marginalized communities.
The Indian River Lagoon (IRL) faces biodiversity threats and water quality challenges exacerbated by climate change, prompting the initiation of the Regional Resiliency Action Plan (RRAP) to address these issues through green infrastructure in Brevard and Volusia counties. The RRAP outlines objectives for prioritizing green infrastructure and promoting habitat connectivity, with ongoing efforts focusing on comprehensive land cover assessments, optimization modeling, and community engagement to support resilience planning and ecological restoration in Brevard County, aligning with Florida Sea Grant priorities and Stetson University’s mission for environmental resilience.
The project addresses inequities in Jacksonville’s urban core by centering the needs of underserved communities and integrating community-designed spatial justice principles into infrastructure planning through participatory action research. Drawing on critical scholarship and recognizing the intersection of justice and infrastructure, particularly in the face of climate change, the project aims to understand and address root causes of spatial injustice, promoting social progress and environmental resilience through community-driven research and advocacy.
