Dr. Weir’s research found that Maui and Hector’s dolphins have high energy needs, must forage and feed almost all the time in order to produce healthy calves and be resilient to disease. This means in addition to managing top threats from toxoplasmosis and fisheries, we must also manage threats from seismic surveying which can disrupt normal foraging and feeding, and we must halt the degradation of the marine environment from land-based impacts such as sedimentation and pollution.
