Article
Full-text available
In species that aggregate for reproduction, the social and fitness costs of movement between groups frequently lead to restricted exchange between breeding areas. We report on four individual humpback whales identified in both the Cape Verde Islands and Guadeloupe; locations separated by an ocean basin and >4000 km. This rate of exchange is rarely...
Article
Full-text available
Unmanned aerial vehicles (UAVs) are increasingly being recognized as potentially useful for detection of marine mammals in their natural habitats, but an important consideration is the associated uncertainties in animal detection. We present a study based on field trials using UAVs to carry out image-based monitoring of cetaceans in two fjords in n...
Article
Full-text available
Humpback whales wintering in the entire West Indies chain are widely treated as comprising a single breeding population. However, most areas outside of Silver Bank and Samana Bay, Dominican Republic, are poorly and sporadically studied. Data is presented on the timing and movement patterns of 262 whales from the southeastern Caribbean, extending fr...
Article
Full-text available
Effective conservation of the endangered North Atlantic humpback whale (Megaptera novaeangliae) which breeds in the eastern North Atlantic around the Cape Verde Islands off West Africa requires information about their spatio-temporal distribution, population size, and migratory patterns. Understanding temporal distribution is particularly important...
Article
Full-text available
In the northern hemisphere, humpback whales ( Megaptera novaeangliae) typically migrate between summer/autumn feeding grounds at high latitudes, and specific winter/spring breeding grounds at low latitudes. Northeast Atlantic (NEA) humpback whales for instance forage in the Barents Sea and breed either in the West Indies, or the Cape Verde Islands,...
Preprint
Full-text available
Rapid climate change in Arctic and Subarctic ecosystems is altering the spatio-temporal dynamics and abundance of resources. Whether highly mobile predators can respond and match their movements to changed resource peaks remains largely unclear. In the last decade, humpback whales ( Megaptera novaeangliae ) established a new foraging site in fjords...

From Norway to Cape Verde: New insights into the migratory behavior of humpback whales in the Eastern North Atlantic
Conference Paper
Full-text available
Humpback whales wintering throughout the West Indies chain are widely treated as comprising a single breeding population. However, most areas outside of the Dominican Republic are poorly and sporadically studied. We present data on the timing and movement patterns of 269 whales from the southeast Caribbean, extending from Antigua in the north to Tr...
Article
Full-text available
Knowledge on the ecology of humpback whales in the eastern North Atlantic is lacking by comparison with most other ocean basins. Humpback whales were historically over-exploited in the region and are still found in low relative abundances. This, coupled with their large range makes them difficult to study. With the aim of informing more effective c...

What is more beautiful on a cold winter’s night than catching a glimpse of the northern lights or “aurora borealis” dancing across the sky? For thousands of years people in the northern part of the world have marveled at the spectacular displays that occasionally light up the night sky. This stunning phenomenon is deeply embedded in the mythology...
Article
Seasonality of biomarker baseline levels were studied in polar cod (Boreogadus saida), caught in Kongsfjorden, Svalbard, in April, July, September and December, 2006-2007. Physiological parameters (condition factor, gonado- and hepato-somatic indexes, energy reserves, potential metabolic activity and antifreeze activity) in polar cod were used to i...

The foraging behaviour of little auks (Alle alle) in the Bjørndalen colony on the western coast of Spitsbergen was studied during the breeding season 2005. The duration of foraging trips and contents of gular pouches were analysed. Quantitative zooplankton samples procured in the vicinity of the colony facilitated a comparison between gular pouch c...
Article
Full-text available
The effects of temperature and body size on the clearance rate of the appendicularian Oikopleura dioica were investigated. The clearance rate increased with the trunk length of the animals according to a power function with exponent 3.2 ± 0.17 (range 2.9–3.8). The intercepts of the three regressions were significantly different with the highest rat...
