Abstract
The possibility of changes in demographic parameters for right whales off South Africa is examined through analysis of resightings data for females with calves over the 1979–2006 period. No statistically significant change in either adult survival rate or population growth rate is detected. However the mean calving interval shows a decrease from 3.2 to 3.1 years somewhere between 1985 and 1990.
