Dear MARMAM community,



My co-authors and I are pleased to inform you about a new publication
titled “Fall distribution and diversity of cetaceans along the southern and
eastern coasts of Hokkaido, Japan” recently published in Regional Studies
in Marine Science.

Abstract

The southern and eastern coasts of Hokkaido, part of the western North
Pacific and the southern Sea of Okhotsk, are productive regions with a high
degree of biodiversity and human activity. This area is an important
habitat for cetaceans. However, only a few studies have been conducted on
comprehensive species co-inhabiting the study area at the same time.
Information regarding cetacean distribution patterns is necessary for
ecosystem management and marine conservation. The objective of this study
was to investigate the distribution patterns and environmental variables
affecting the distribution of cetaceans in coastal Hokkaido using sighting
surveys. Five baleen and seven toothed whale species were observed during
the study period. The maximum entropy model used to map the distribution of
11 selected cetacean species showed a heterogeneous distribution, which may
reflect a potentially suitable habitat for each species. In the North
Pacific region, there are differences in water temperature between east and
west of Cape Erimo, which is possibly the reason why some species are only
distributed in the eastern side. In the Nemuro Strait, the distribution
differs from north to south, likely influenced by seafloor topography. Our
results will help to clarify the habitat of various cetacean species in
coastal Hokkaido and provide essential information for their conservation.
