To understand the potential of migrants to adjust to perturbations, it is critical to study the connection of different areas used by different populations during the annual cycle (i.e. migratory connectivity). Using a large-scale tracking data set of 662 individual seabirds from 2 sympatric auk meta-populations (common guillemots <jats:italic>Uria aalge<\/jats:italic> and Br\u00fcnnich\u2019s guillemots <jats:italic>U. lomvia<\/jats:italic>) breeding in 12 colonies throughout the Northeast Atlantic, we estimated migratory connectivity in seasonal space use as well as occupied environmental niches. We found strong migratory connectivity, within and between species. This was apparent through a combination of seasonal space use and occupied environmental niches. Br\u00fcnnich\u2019s guillemot populations grouped into 2 and common guillemot populations into 5 previously undescribed spatiotemporal clusters. Common guillemot populations clustered in accordance with the variable population trends exhibited by the species, while Br\u00fcnnich\u2019s guillemot populations are declining everywhere where known within the study area. Individuals from different breeding populations in both species were clustered in their space and environmental use, utilising only a fraction of the potential species-wide range. Further, space use varied among seasons, emphasising the variable constraints faced by both species during the different stages of their annual cycle. Our study highlights that considering spatiotemporal dynamics, not only in space but also in occupied environmental niches, improves our understanding of migratory connectivity and thus population vulnerability in the context of global change.<\/jats:p>","DOI":"10.3354\/meps13580","type":"journal-article","created":{"date-parts":[[2020,11,25]],"date-time":"2020-11-25T09:45:24Z","timestamp":1606297524000},"page":"173-188","update-policy":"https:\/\/doi.org\/10.3354\/policy","source":"Crossref","is-referenced-by-count":19,"title":["Strong migratory connectivity across meta-populations of sympatric North Atlantic seabirds"],"prefix":"10.3354","volume":"676","author":[{"given":"B","family":"Merkel","sequence":"first","affiliation":[{"name":"Norwegian Polar Institute, Fram Centre, PO Box 6606 Langnes, 9296 Troms\u00f8, Norway"},{"name":"Department of Arctic and Marine Biology, University of Troms\u00f8\u2014The Arctic University of Norway, 9037 Troms\u00f8, Norway"},{"name":"Akvaplan-niva, Fram Centre, PO Box 6606 Langnes, 9296 Troms\u00f8, Norway"}]},{"given":"S","family":"Descamps","sequence":"additional","affiliation":[{"name":"Norwegian Polar Institute, Fram Centre, PO Box 6606 Langnes, 9296 Troms\u00f8, Norway"}]},{"given":"NG","family":"Yoccoz","sequence":"additional","affiliation":[{"name":"Department of Arctic and Marine Biology, University of Troms\u00f8\u2014The Arctic University of Norway, 9037 Troms\u00f8, Norway"}]},{"given":"D","family":"Gr\u00e9millet","sequence":"additional","affiliation":[{"name":"Centre d\u2019Ecologie Fonctionnelle et Evolutive, UMR 5175, CNRS\u2014Universit\u00e9 de Montpellier\u2014Universit\u00e9 Paul-Val\u00e9ry Montpellier\u2014EPHE, Montpellier, France"},{"name":"FitzPatrick Institute, DST-NRF Centre of Excellence at the University of Cape Town, Rondebosch 7701, South Africa"}]},{"given":"P","family":"Fauchald","sequence":"additional","affiliation":[{"name":"Norwegian Institute for Nature Research, Fram Centre, PO Box 6606 Langnes, 9296 Troms\u00f8, Norway"}]},{"given":"J","family":"Danielsen","sequence":"additional","affiliation":[{"name":"University of the Faroe Islands, Vestarabryggja 15, 100 T\u00f3rshavn, Faroe Islands"}]},{"given":"F","family":"Daunt","sequence":"additional","affiliation":[{"name":"Centre for Ecology & Hydrology, Bush Estate, Penicuik, Midlothian EH26 0QB, UK"}]},{"given":"KE","family":"Erikstad","sequence":"additional","affiliation":[{"name":"Norwegian Institute for Nature Research, Fram Centre, PO Box 6606 Langnes, 9296 Troms\u00f8, Norway"},{"name":"Centre for Biodiversity Dynamics, Department of Biology, Norwegian University of Science and Technology, 7491 Trondheim, Norway"}]},{"given":"AV","family":"Ezhov","sequence":"additional","affiliation":[{"name":"Murmansk Marine Biological Institute, 17 Vladimirskaya Street, 183010 Murmansk, Russia"}]},{"given":"MP","family":"Harris","sequence":"additional","affiliation":[{"name":"Centre for Ecology & Hydrology, Bush Estate, Penicuik, Midlothian EH26 0QB, UK"}]},{"given":"M","family":"Gavrilo","sequence":"additional","affiliation":[{"name":"Association Maritime Heritage, 199106, Icebreaker \"Krassin\", The Lieutenant Schmidt emb., 23 Line, Saint Petersburg, Russia"},{"name":"National Park Russian Arctic, 168000, Sovetskikh Kosmonavtov Ave. 57, Archangelsk, Russia"}]},{"given":"SH","family":"Lorentsen","sequence":"additional","affiliation":[{"name":"Norwegian Institute for Nature Research, PO Box 5685 Sluppen, 7485 Trondheim, Norway"}]},{"given":"TK","family":"Reiertsen","sequence":"additional","affiliation":[{"name":"Norwegian Institute for Nature Research, Fram Centre, PO Box 6606 Langnes, 9296 Troms\u00f8, Norway"}]},{"given":"GH","family":"Systad","sequence":"additional","affiliation":[{"name":"Norwegian Institute for Nature Research, Thorm\u00f8hlensgate 55, 5006 Bergen, Norway"}]},{"given":"T","family":"Lindberg Th\u00f3rarinsson","sequence":"additional","affiliation":[{"name":"Northeast Iceland Nature Research Centre, Hafnarst\u00e9tt 3, 640 H\u00fasav\u00edk, Iceland"}]},{"given":"S","family":"Wanless","sequence":"additional","affiliation":[{"name":"Centre for Ecology & Hydrology, Bush Estate, Penicuik, Midlothian EH26 0QB, UK"}]},{"given":"H","family":"Str\u00f8m","sequence":"additional","affiliation":[{"name":"Norwegian Polar Institute, Fram Centre, PO Box 6606 Langnes, 9296 Troms\u00f8, Norway"}]}],"member":"1913","reference":[{"key":"Ref1","unstructured":"Amante C, Eakins BW (2009) ETOPO1 1 arc-minute global relief model: procedures, data sources and analysis.
