Distribution and abundance of large whales in Norwegian and adjacent waters based on ship surveys 1995-2001

NAMMCO Scientific Publications, 2009
The abundances of large whale species are presented for the northeast Atlantic from near-complete survey coverage in 1995 and from multiple partial-area surveys during 1996-2001.

Timing is everything: Drivers of interannual variability in blue whale migration. [PDF]

, 2020
Blue whales need to time their migration from their breeding grounds to their feeding grounds to avoid missing peak prey abundances, but the cues they use for this are unknown.

A review of the historic and present ecological role of aquatic and shoreline wood, from forest to deep sea

Biological Reviews, EarlyView.
ABSTRACT The ecology of forests, their losses, and terrestrial wood decomposition dynamics have been intensively studied and reviewed. In the aquatic realm, reviews have concentrated on large wood (LW) in rivers and the transition from freshwater to marine environments in the Pacific Northwest of North America. However, a comprehensive global synthesis

Frequency of Injuries from Line Entanglements, Killer Whales, and Ship Strikes on Bering-Chukchi-Beaufort Seas Bowhead Whales

, 2017
We analyzed scarring data for Bering-Chukchi-Beaufort (BCB) Seas bowhead whales ( Balaena mysticetus ) harvested by Alaska Native hunters to quantify the frequency of line entanglement, ship strikes, and killer whale-inflicted injuries.

Heavy with child? Pregnancy status and stable isotope ratios as determined from biopsies of humpback whales

Conservation Physiology, 2016
Recent advances in analytical techniques have allowed cetacean pregnancy status to be diagnosed using reproductive hormones from biopsy samples. We tested the efficacy of blubber progesterone assays for diagnosing pregnancy in humpback whales, calculated

Shaping research in marine functional connectivity for integrated and effective marine science and management

Biological Reviews, EarlyView.
ABSTRACT Effective knowledge of ecological connectivity at sea and at the land–sea interface is key to supporting global policy goals to conserve and restore ocean biodiversity and function. However, a persistent lack of commonality in terminology and understanding around the concept of connectivity in marine ecological studies hampers its integration ...

Joint power control and user grouping mechanism for efficient uplink non‐orthogonal multiple access‐based 5G communication: Utilising the Lèvy‐flight firefly algorithm

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 ...

Capture and killing of small cetaceans in the Faroe Islands is inhumane and offers little scope for improvement

Frontiers in Marine Science
The capture and killing of free-living small cetaceans in the Faroe Islands is described. After being driven on-shore by motor vessels, the animals are killed without pre-stunning using officially-prescribed methods that involve severing the spinal cord ...
