To assess the efficacy of translocating seals to areas of greater prey availability, 12 weanling monk seals were translocated with pre-release health screening and post-release monitoring.
We individually identified 297 monk seals between 1988 and 2014 and recorded that 83 (28 percent) of these had at least one documented hooking or entanglement.
Visual observations of individually identifiable monk seals associating onshore were used to estimate contact rates, assuming random mixing, and also to investigate contact patterns of different age and sex classes.
As Hawaiian monk seal population numbers continue to decline, outstanding fine-scale genetic questions require enhanced genotyping capacity of a rich archive of specimens.
Twenty seals were outfitted with tracking devices to map their home ranges, which were then compared with the persistent organic pollutants in their serum.
Validation of fecal glucocorticoid (GC) and thyroid (T3) hormone metabolite measures in the critically endangered Hawaiian monk seal. Examination of variation in the concentrations of these hormones in individuals across the species' range.
