Climate and density-dependence cause changes in adult sex ratio in a large Arctic herbivore
Peeters, Bart; Veiberg, Vebjørn; Pedersen, Åshild Ønvik; Stien, Audun; Irvine, Robert Justin; Aanes, Ronny; Sæther, Bernt-Erik; Strand, Olav; Hansen, Brage Bremset (Journal article; Peer reviewed, 2017)Variation in adult sex ratio (ASR) affects population demography and dynamics of large mammals. The mechanisms behind this variation are largely unclear, but may be partly related to climatic drivers and density dependence ... -
Effects of Climate and Animal Density on Adult Sex Ratio Variation in a Large Herbivore
Peeters, Bart (Master thesis, 2014)Adult sex ratio is often biased in natural populations, and its variation is known to influence different demographic components at the population level. The causes of variation in adult sex ratio remain, however, poorly ... -
Population dynamics under climate change ad harvesting: Results from the high Arctic Svalbard reindeer
Peeters, Bart (Doctoral theses at NTNU;2019:268, Doctoral thesis, 2019)To prevent populations or species extinctions due to anthropogenic global change, we need a better mechanistic understanding of the interplay between intrinsic (e.g. resource competition, demographic structure) and extrinsic ... -
Sea ice loss increases genetic isolation in a high Arctic ungulate metapopulation
Peeters, Bart; Le Moullec, Mathilde; Raeymaekers, Joost A. M.; Fredricson Marquez, Jonatan; Røed, Knut; Pedersen, Åshild Ønvik; Veiberg, Vebjørn; Loe, Leif Egil; Hansen, Brage Bremset (Peer reviewed; Journal article, 2019)Sea ice loss may have dramatic consequences for population connectivity, extinction–colonization dynamics, and even the persistence of Arctic species subject to climate change. This is of particular concern in face of ... -
Spatial heterogeneity in climate change effects decouples the long‐term dynamics of wild reindeer populations in the high Arctic
Hansen, Brage Bremset; Pedersen, Åshild Ønvik; Peeters, Bart; Le Moullec, Mathilde; Albon, Steve D.; Herfindal, Ivar; Sæther, Bernt-Erik; Grøtan, Vidar; Aanes, Ronny (Journal article; Peer reviewed, 2019)The ‘Moran effect’ predicts that dynamics of populations of a species are synchronized over similar distances as their environmental drivers. Strong population synchrony reduces species viability, but spatial heterogeneity ... -
Spatiotemporal patterns of rain-on-snow and basal ice in high Arctic Svalbard: detection of a climate-cryosphere regime shift
Peeters, Bart; Pedersen, Åshild Ønvik; Loe, Leif Egil; Isaksen, Ketil; Veiberg, Vebjørn; Stien, Audun; Kohler, Jack; gallet, jean-charles; Aanes, Ronny; Hansen, Brage Bremset (Journal article; Peer reviewed, 2018)Arctic winters have become increasingly warmer and rainier. Where permafrost prevails, winter rain (or rain-on-snow; ROS) is known to occasionally cause extensive ice layers at the snow/ground interface, i.e. "basal ice" ...
