Maintaining a stable core body temperature is essential for endotherms. Cetaceans live in a highly thermally conductive medium, requiring special adaptations to reduce heat loss and maintain homeothermy. We employed a combination of aerial photogrammetry and existing data sources to estimate heat loss rates in five sympatric cetaceans of varying sizes, inhabiting the sub-arctic waters (∼3.

Unoccupied aerial vehicles (UAVs), or "drones," are increasingly used as a tool for cetacean research, but knowledge about how these tools contribute to underwater sound is lacking. In this study, underwater sound levels of three commonly used UAV models (Mavic Pro Platinum, Phantom 4 Pro v2.0, Inspire 1 Pro) were recorded.

Quantifying the energy expenditure of animals is critical to understanding the cost of anthropogenic disturbance relative to their overall energy requirements. We used novel drone focal follows (776 follows, 185 individuals) and aerial photogrammetry (5372 measurements, 791 individuals) to measure the respiration rate and body condition loss of southern right whales (Eubalaena australis) on a breeding ground in Australia. Respiration rates were converted to oxygen consumption rate and field metabolic rate (FMR) using published bioenergetic models.

Article Synopsis
  • The Southern Ocean's changing physical properties are negatively affecting the survival of Antarctic krill, which in turn impacts predators like the southern right whale that depend on these krill for energy.
  • Over the past decade, monitoring of southern right whales has revealed a reduced reproductive rate and a change in their foraging habits, likely linked to their declining access to food resources.
  • A study using aerial photogrammetry showed a 23% drop in maternal body condition among these whales, highlighting the link between Southern Ocean productivity and the well-being of capital breeders as they adapt to climate change.
