Southeastern Pacific humpback whales ( Megaptera novaeangliae ) and their breeding grounds: Distribution and habitat preference of singers and social groups off the coast of Ecuador
Abstract Understanding the distribution, habitat preference, and social structure of highly migratory species at important life history stages ( e.g ., breeding and calving) is essential for conservation efforts. We investigated the spatial distribution and habitat preference of humpback whale socia...

Abstract Understanding the distribution, habitat preference, and social structure of highly migratory species at important life history stages ( e.g ., breeding and calving) is essential for conservation efforts.

In contrast, competitive groups showed no clear habitat preference and exhibited social segregation from other whales. Understanding the habitat preference and distribution of humpback whales on breeding and calving grounds vulnerable to anthropogenic disturbance provides important baseline information that should be incorporated into conservation efforts at a regional scale. |
