Diseases of Aquatic Organisms (2017)

There is increasing public interest in the overall health of the marine environment. Harbor porpoises Phocoena phocoena have a coastal distribution, and stranded animals function as sentinels for population and…


Dead useful; methods for quantifying baseline variability in stranding rates to improve the ecological value of the strandings record as a monitoring tool

ten Doeschate, Mariel T. I.; Brownlow, Andrew C.; Davison, Nicholas J.; Thompson, Paul M.
Journal of the Marine Biological Association of the United Kingdom (2017)

The ecological value of the stranding record is often challenged due to the complexity in quantifying the biases associated with multiple components of the stranding process. There are biological, physical…
