Warming Oceans May Be Causing One Whale Species To Have Fewer Calves
- New research links warmer oceans to longer calving intervals in southern right whales.
- Some mothers now have calves every four years, up from about three years.
- Scientists studied decades of whale observations along Australian coastlines to identify the trend.
- The study links changes in krill availability to warmer waters as a possible cause.
- Slower reproduction could complicate recovery despite the species’ overall rebound.
- Long-term data show a gradual increase in calving intervals over time.
- The findings illustrate how climate change affects ocean ecosystems in complex ways.
- Researchers monitored individual whales returning to calving grounds year after year.
- Southern right whales began recovering from commercial whaling, aiding conservation prospects.
- Researchers emphasize continued monitoring to understand future population dynamics.
