Description

Yacine Ben Chehida and co-authors track genetic change in Iberian harbor porpoises in work from 2023. The Iberian group is an edge population adapted to local upwelling, distinct from porpoises further north. The work covers the last thirty years in Iberian waters.

Comparing samples from 1990 to 2002 with samples from 2012 to 2015, the team found a sharp drop in genetic diversity. Two southern animals carried a lineage close to the Mauritanian group, hinting at some movement between them. Model tests favor a real fall in population size over mere drift in a small group. The authors urge urgent conservation steps.
