Sarah Malick-Wahls, Auteur ; Ingvar Byrkjedal, Auteur ; Barbara Ganter, Auteur ; Jan T. Lifjeld, Auteur ; Gunnhild Marthinsen, Auteur ; Hans-Ulrich Rösner, Auteur ; Terje Lislevand, AuteurThe sex of Dunlins from two widely separated Norwegian breeding populations can be determined using morphometrics, with the Dunlins’ sizes differing between populations. We aimed to understand the Dunlin’s physical characteristics within and out[...]

Aleš Svoboda, Auteur ; Gunnhild Marthinsen, Auteur ; Václav Pavel, Auteur ; Bohumír Chutný, Auteur ; Lucia Turčoková, Auteur ; Jan T. Lifjeld, Auteur ; Arild Johnsen, AuteurLong-distance migratory birds are potentially exposed to a range of blood sucking arthropods that transmit avian blood parasites. Because of differential vector exposure, the parasite fauna may vary in different habitat types, among populations,[...]
Article
Liv Wennerberg, Auteur ; Gunnhild Marthinsen, Auteur ; Jan T. Lifjeld, AuteurBreeding populations of southern dunlin Calidris alpina schinzii in South Fennoscandia and the Baltic are severely fragmented and declining dramatically. Information on the genetic structure and diversity is therefore of importance for the conse[...]
Article
Oddmund Kleven, Auteur ; Gunnhild Marthinsen, Auteur ; Jan T. Lifjeld, AuteurGenetic studies have shown that extra-pair paternity is widespread among socially monogamous bird species. Yet, the role of males and females and their behavior leading to this mixed reproductive strategy is poorly understood. Here, we analyze p[...]

While the teydea population is large and stable, the polatzeki population unde[...]
Article
Terje Lislevand, Auteur ; Gunnhild Marthinsen, Auteur ; Jan T. Lifjeld, AuteurThere have been very few reports of body size measurements of live Temminck's Stints, but earlier studies have shown sex differences in body mass and tarsus length. Here we use molecular techniques to determine the sex of Temminck's Stints from [...]

Hanna N. Stostad, Auteur ; Silje L. Rekdal, Auteur ; Oddmund Kleven, Auteur ; Terje Laskemoen, Auteur ; Gunnhild Marthinsen, Auteur ; Arild Johnsen, Auteur ; Jan T. Lifjeld, AuteurSperm morphology is highly diversified among species and at higher taxonomic levels. In birds, there is also increasing evidence of geographical differentiation in sperm traits within species, especially in those with strong sperm competition. G[...]

Jan T. Lifjeld, Auteur ; Gunnhild Marthinsen, Auteur ; Magne Myklebust, Auteur ; Deborah A. Dawson, Auteur ; Arild Johnsen, AuteurWe present photographic and molecular evidence of a wild Marsh Warbler x Sedge Warbler (Acrocephalus palustris x A. schoenobaenus) hybrid that occurred over three breeding seasons (2007-2009) near Trondheim, Central Norway. The bird had the appe[...]
