This paper develops a multistate capture-recapture model to estimate calving probabilities in North Atlantic right whales using sightings data from 1990-2019, finding decreased calving rates after a 2010 regime shift and links to prey availability and severe injury.

This study estimates cause-specific injury and mortality rates of North Atlantic right whales using a multistate capture-recapture model, finding increased entanglement injuries and mortality in females with calves.

The paper quantifies reproductive performance decline in North Atlantic right whales by comparing observed calf numbers to theoretical maximums, finding reproductive performance at 27% of expected.

The paper estimates population dynamics of North Atlantic humpback whales in the Gulf of Maine from 2000 to 2019, finding increased abundance but declining calf survival and sex ratio shifts.
