Frontiers in Marine Science, 2022 Climate change is a global phenomenon, yet impacts on resource availability to predators may be spatially and temporally diverse and asynchronous. As capital breeders, whales are dependent on dense, predictable prey resources during foraging seasons.

Spatio-temporal patterns of beaked whale echolocation signals in the North Pacific. [PDF]
, 2014 At least ten species of beaked whales inhabit the North Pacific, but little is known about their abundance, ecology, and behavior, as they are elusive and difficult to distinguish visually at sea.

Spatial and seasonal distribution of American whaling and whales in the age of sail. [PDF]
PLoS ONE, 2012 American whalemen sailed out of ports on the east coast of the United States and in California from the 18(th) to early 20(th) centuries, searching for whales throughout the world's oceans.

Thermal Footprints of Whales [PDF]
Oceanography, 2009 Under the right meteorological conditions, whales can leave a trail of cool spots on the ocean surface that are detectable in infrared images. When the wind is light and the sun is shining, the surface water warms to produce a thermal gradient in the top

Killer whales and whaling: the scavenging hypothesis [PDF]
Biology Letters, 2005 Killer whales (Orcinus orca) frequently scavenged from the carcasses produced by whalers. This practice became especially prominent with large-scale mechanical whaling in the twentieth century, which provided temporally and spatially clustered floating carcasses associated with loud acoustic signals.

North Atlantic blue and fin whales suspend their spring migration to forage in middle latitudes: building up energy reserves for the journey? [PDF]
PLoS ONE, 2013 The need to balance energy reserves during migration is a critical factor for most long-distance migrants and an important determinant of migratory strategies in birds, insects and land mammals.

IET Networks, EarlyView., 2023 We utilise a metaheuristic optimisation method, inspired by nature, called the Lévy‐flight firefly algorithm (LFA), to tackle the power regulation and user grouping in the NOMA systems. Abstract The non‐orthogonal multiple access strategies have shown promise to boost fifth generation and sixth generation wireless networks' spectral efficiency and ...
