“…Some work has been done creating so-called backpacks for bivalves, containing all the electronic components necessary for measuring behavioural metrics and transmitting collected data, as well as a battery (e.g. Taylor et al, 2013). Untethering allows observation of a more natural mode of life, particularly desirable where mobile species of bivalve are employed.…”

Biological early warning systems (BEWSs) monitor the behaviour or physiology of living organisms as an indirect mechanism to sense local environmental changes, and have become a widely established tool for monitoring water pollution. Complementary to conventional chemical and physical techniques, their strength lies in the ability to continuously monitor water quality, providing direct and rapid warning of toxic discharges. Bivalve molluscs (mussels and clams) are ideal sensing organisms for BEWSs, owing to their: high water filtration capacity; sensitivity to numerous, diverse pollutants; considerable longevity; high abundance; and wide range of physical responses to environmental change. Two behavioural metrics of bivalves have dominated in ecotoxicological studies, and consequently spawned development into BEWSs: valve movements, typically measured using electromagnetic techniques; and bivalve cardiac activity, typically measured using infrared photoplethysmography. However, other, less studied bivalve behaviours may exhibit pollutant impacts, including shell growth and dissolution, premature egg/larval release, horizontal movement, and burial. Such metrics may, with further research, provide bases for future BEWSs, some through current valve movement monitoring technology, others potentially through acoustic telemetry. Future bivalve-based BEWSs may become more informative and sensitive through the greater nuance that lies in integration of different metrics simultaneously and/or multi-species monitoring. Future directions may seek techniques that reduce disturbance to bivalves and enable observation of a more natural mode of behaviour, through using untethered, or entirely unequipped, specimens. With rigorous controls for individual- and population-level variation, bivalves have great power as biosensors and, bolstered by the scope for future advancements, this field has the potential to make significant contributions to future water quality management.

I would like to extend my profound gratitude to Dr. James J. Niemeier for his mentorship and contribution to innumerable experiments and discussions on the different research projects that we worked on together. The IIHR Hydroscience and Engineering Laboratories staff, my fellow students and undergraduate research assistants for their help. Hannah Taylor for her help with initial prototypes of testing radio boards. Robert B. Hart (Gabriel) for his time as diver in the underwater experiments at the University of Iowa Aquatic Center diving pool. Jeffrey T. Schnell, high school intern, for his assistance with some of the initial experiments (Summer 2013) and 3-D modeling of cybermussel's backpack (Summer 2014). Matthew J. Janechek for his wonderful help in the 3-D curved spiral antenna modeling and 3-D printing of the antenna housing fixture. Michael J. Salino-Hugg for his assistance during the last stage of the research in testing the radioantenna system assemblage and underwater antenna measurements at the Wind Tunnel Annex Laboratory facilities water tank. Kathryn Temple for her assistance on the mussel shell material characterization related measurements. I express my gratitude to the following IIHR's shop staff for their collaboration in numerous tasks: Brandon Barquist, Christian Borgwardt, Nicholas T. Thornburg, Timothy J. Houser, among others.
