Both species are listed as Data Deficient by the IUCN, mainly due to the lack of information about population sizes and trends.
The goal of this study was to build spatially explicit models for the abundance of both species in relation to environmental variables using data collected during eight scientific cruises along the Patagonian shelf. Spatial models were constructed using generalized additive models.
In total, 88 schools individuals of Commerson's dolphin and schools individuals of Peale's dolphin were recorded in 8, km surveyed. Commerson's dolphin was found less than 60 km from shore; whereas Peale's dolphins occurred over a wider range of distances from the coast, the number of animals sighted usually being larger near or far from the coast.
Fitted models indicate overall abundances of approximately 22, Commerson's dolphins and 20, Peale's dolphins in the total area studied. This work provides the first large-scale abundance estimate for Peale's dolphin in the Atlantic Ocean and an update of population size for Commerson's dolphin.
Additionally, our results contribute to baseline data on suitable habitat conditions for both species in southern Patagonia, which is essential for the implementation of adequate conservation measures.
