International Journal of Comparative Psychology (2019)

The number of welfare-oriented studies is increasing in animals under human care, including odontocetes. However, validated welfare indicators are lacking for captive odontocetes. We studied the effect of several conditions…


Clinical, pathological, and laboratory diagnoses of diseases of harbour porpoises (Phocoena phocoena), live stranded on the Dutch and adjacent coasts from 2003 to 2016

Harbour porpoises (Phocoena phocoena) in the North Sea live in an environment heavily impacted by humans, the consequences of which are a concern for their health. Autopsies carried out on…


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…


Estimation of population size and trends for highly mobile species with dynamic spatial distributions

Boyd, Charlotte; Barlow, Jay; Becker, Elizabeth A.; Forney, Karin A.; Gerrodette, Tim; Moore, Jeffrey E.; Punt, André E.
Diversity and Distributions (2017)

Conventional spatial density models assume a constant relationship between densities and habitat covariates over some time period, typically a survey season. The estimated population size must change whenever total habitat…


Quantifying parasite presence in relation to biological parameters of harbour porpoises Phocoena phocoena stranded on the Dutch coast

ten Doeschate, M. T. I.; IJsseldijk, L. L.; Hiemstra, S.; de Jong, E. A.; Strijkstra, A.; Gröne, A.; Begeman, L.
Diseases of Aquatic Organisms (2017)

Harbour porpoises are often found to be infected by endoparasites in several organs including the lungs and stomach as well as the heart, liver and ears. Nevertheless there is still…
