Molecular Ecology, 30(19), 4642-4659. https://doi.org/10.1111/mec.16086

Many marine species exhibit fine-scale population structure despite high mobility and a lack of physical barriers to dispersal, but the evolutionary drivers of differentiation in these systems are generally poorly understood. Here we investigate the... Read More about Population structure associated with bioregion and seasonal prey distribution for Indo‐Pacific bottlenose dolphins (Tursiops aduncus) in South Africa.
