    • Determination of growth, mass, and body mass index of harbour porpoises (Phocoena phocoena): Implications for conservational status assessment of populations 

      Stepien, Emilie Nicoline; Nabe–Nielsen, Jacob; Hansen, Kirstin Anderson; Kristensen, Jakob Højer; Blanchet, Marie-Anne; Brando, Sabrina; Desportes, Geneviève; Lockyer, Christina; Marcenaro, Lauro; Bunskoek, Paulien; Kemper, José; Siebert, Ursula; Olsen, Morten Tange; Wahlberg, Magnus (Journal article; Tidsskriftartikkel; Peer reviewed, 2023-01-27)
      Longitudinal data on individual growth and seasonal changes in body mass, girth, and blubber thickness are rarely available for cetaceans, making it difficult to assess their population composition and individual nutritional condition. During different time intervals from 1997 to 2020, we collected longitudinal data on length, body mass, girth,and blubber thickness from seventeen harbour porpoises ...

    • Evolutionary history and seascape genomics of Harbour porpoises (Phocoena phocoena) across environmental gradients in the North Atlantic and adjacent waters 

      Celemín, Enrique; Autenrieth, Marijke; Roos, Anna; Pawliczka, Iwona; Quintela, Maria; Lindstrøm, Ulf Ove; Benke, Harald; Siebert, Ursula; Lockyer, Christina; Berggren, Per; Özturk, A. Amaha; Özturk, Bayram; Lesage, Véronique; Tiedemann, Ralph (Journal article; Tidsskriftartikkel; Peer reviewed, 2023-09-08)
      The Harbour porpoise (Phocoena phocoena) is a highly mobile cetacean species primarily occurring in coastal and shelf waters across the Northern hemisphere. It inhabits heterogeneous seascapes broadly varying in salinity and temperature. Here, we produced 74 whole genomes at intermediate coverage to study Harbour porpoise's evolutionary history and investigate the role of local adaptation in the ...

    • Report of the Workshop on Age Estimation in Monodontids 

      Hohn, Aleta A.; Lockyer, Christina; Acquarone, Mario (Journal article; Tidsskriftartikkel; Peer reviewed, 2016)
      The workshop was a 2-day event organised immediately before the Society for Marine Mammalogy biennial conference in Tampa. NAMMCO funding enabled participation of 4 invited experts and also supported the organization and logistics associated with the workshop. The breadth and depth of the workshop presentations made it clear that most issues concerning monodontid age estimation are not unique. Many ...
