Highly Mobile Seabirds Reveal Areas of Conservation Importance Across the Atlantic Ocean

Marie‐Morgane Rouyer, Ana S. L. Rodrigues, Tammy E. Davies, Bethany L. Clark et autres

ABSTRACT Countries have committed to expanding the marine protected area (MPA) network to 30% of the world's ocean by 2030, more than tripling current coverage, and focusing on areas important for biodiversity. For such expansion to translate into effective conservation of marine …

Day length may impose an ecological constraint on chick provisioning behaviour in a high-latitude seabird

Katrina Siddiqi-Davies, Natasha Gillies, Sarah Bond, Jóhannis Danielsen et autres

Abstract Variation in daylight hours may shape light-dependent behaviours both across seasons and among latitudinally distinct breeding colonies. We investigated the influence of photoperiod variation on chick provisioning behaviour in a high-latitude seabird, the Manx shearwater (Puffinus puffinus), a visual hunter that …

Male and adult northern fulmars Fulmarus glacialis are disproportionately taken as bycatch in Northeast Atlantic longline fisheries

Signe Christensen-Dalsgaard, Graeme William Shannon, Jóhannis Danielsen, Jan Andries Van Franeker et autres

Fisheries bycatch is one of the leading causes of seabird mortality across the globe, making it an urgent conservation priority. To quantify the impact on affected seabird populations and develop targeted mitigation strategies, it is crucial to understand the demographic patterns of …

Unifying local and large-scale drivers of the Faroe shelf ecosystem

Hjálmar Hátún, Jóhannis Danielsen, Bergur Olsen, Sólvá Jacobsen et autres

Demersal fish stocks and seabird populations on the Faroe shelf have declined profoundly over the past half-century, and the relative role of exploitation and climate remains a key question. The dynamics of the subpolar gyre influences both the marine climate and several …

Ecosystem based management of sandeels, demersal fish and seabirds in Boreal ecosystems in Northeast Atlantic

Pétur Steingrund, Tycho Anker‐Nilssen, Valur Bogason, Jóhannis Danielsen et autres

The current project aims to explore the potential of ecosystem based management on the marine shelves at Iceland, Faroe Islands and Norway. It was found that oceanographich features like the size of the subpolar gyre or the strength of the East Icelandic …

Half a century of environmental variability and seabird trends on the Faroe Shelf in the North Atlantic Ocean

Bergur Olsen, Tycho Anker‐Nilssen, Jóhannis Danielsen, Eilif Gaard et autres

The Faroe Shelf, located on the North Atlantic’s Iceland-Scotland ridge, has historically hosted a rich ecosystem with large seabird populations. However, substantial declines in their population sizes have been observed over the past half century. This study introduces and documents comprehensive decades-long …

Night flight facilitates late breeding catch-up in a long-distance migratory seabird

Katrina Siddiqi-Davies, Joe Wynn, Oliver Padget, Sarah Bond et autres

Long-distance migrants must optimise their timing of breeding to capitalise on resources at both breeding and over-wintering sites. In species with protracted breeding seasons, departing earlier on migration might be advantageous, but is constrained by the ongoing breeding attempt. Here we investigated …
