The importance of the subarctic gyres of the North Pacific Ocean to marine birds and mammals is poorly known because of a paucity of data spanning appropriate scales of time and space.

The little information that is available indicates the western subarctic gyre (WSAG) is more productive than the eastern subarctic gyre (ESAG).Cited by: – Precipitous declines in abundance of multiple marine mammal species in the north Pacific since s (northern fur seal, harbor seal, sea otter) – Incidental mortality from fisheries and intentional harvesting (s s) initial cause, but not continued decline File Size: 5MB.

The geographic distribution of studies within the database reflects the distribution of these four marine mammal species ().Harbor seals range along the entire Northeast Pacific from central Baja California to the end of the Aleutian Island chain (Caretta et al., ).Consequently, we found diet studies for harbor seals in every one of the six geographic cells in our by: 9.

Invasive mammals have irreversibly altered ecosystems of Hawai‘i and other tropical Pacific islands in numerous cases through novel herbivory, predation, and diseases, thereby causing the disproportionate extinction of flora and fauna that occur nowhere else on Earth.

You observe that all four species feed on insects. However, you notice that the species do not feed at the same time of day: one species feeds most actively at dawn, another during the middle of the day, another at dusk, and the last species feeds at night.

They show that the Pacific Ocean's top predators move across an ever-changing oceanic landscape, in order to enjoy shifting biological feasts, that move with the the currents and the seasons. Seabirds (also known as marine birds) are birds that are adapted to life within the marine environment.

While seabirds vary greatly in lifestyle, behaviour and physiology, they often exhibit striking convergent evolution, as the same environmental problems and feeding niches have resulted in similar adaptations. The first seabirds evolved in the Cretaceous period, and modern seabird families.

Originally published inthis book is concerned with the ways in which seabirds function as predators in the marine environment; in particular about how they find and catch food and how much of it they consume.

This article considers the role of marine mammals in a sea or ocean ecosystem based on the example of the Far Eastern seas with adjacent waters of the North Pacific, which is one of the regions of the World Ocean that is distinguished by its high biological and fish capacity and by a high abundance of cetaceans and pinnipeds.
