During dedicated surveys for the Critically Endangered eastern stock of North Pacific right whales (Eubalaena japonica) in the Bering Sea, focal follows (FFs) were combined with passive acoustic monitoring to correlate vocal activity with dive behavior.
A new method for obtaining abundance estimates of Hawaiian monk seals that relies upon the proportion of the non-pup population observed in standardized counts at other sites with known abundance.
Investigation and description of the foraging behavior of monk seals in the main Hawaiian Islands, including a metric to classify foraging behavior from telemetry instruments.
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.
This project was designed to gather and synthesize information about the ecology of the seals within Iliamna Lake through a combination of aerial surveys, biological sampling, and ethnographic research.
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.
