An assessment of relative habitat use as a metric for species’ habitat association and degree of specialization
O'Reilly, Enya; Gregory, Richard D.; Aunins, Ainars; Brotons, Llúis; Chodkiewicz, Tomasz; Escandell, Virginia; Foppen, Ruud P. B.; Gamero, Anna; Herrando, Sergi; Jiguet, Frédéric; Kålås, John Atle; Kamp, Johannes; Klvanova, Alena; Lehikoinen, Aleksi; Lindström, Åke; Massimino, Dario; Øien, Ingar Jostein; Reif, Jiri; Šilarová, Eva; Teufelbauer, Norbert; Trautmann, Sven; van Turnhout, Chris; Vikstrøm, Thomas; Vorisek, Petr; Butler, Simon J. (Peer reviewed; Journal article, 2021)In order to understand species’ sensitivity to habitat change, we must correctly determine if a species is associated with a habitat or not, and if it is associated, its degree of specialization for that habitat. However, ... -
Bird population declines and species turnover are changing the acoustic properties of spring soundscapes
Morrison, C.A.; Auniņš, A.; Benkő, Z.; Brotons, L.; Chodkiewicz, T.; Chylarecki, P.; Escandell, V.; Eskildsen, D. P.; Gamero, A.; Herrando, S.; Jiguet, F.; Kålås, John Atle; Kamp, J.; Klvaňová, A.; Kmecl, P.; Lehikoinen, A.; Lindström, Åke; Moshøj, C.; Noble, D. G.; Øien, Ingar Jostein; Paquet, J-Y.; Reif, J.; Sattler, T.; Seaman, B. S.; Teufelbauer, N.; Trautmann, S.; van Turnhout, C. A. M.; Vořišek, P.; Butler, S.J. (Peer reviewed; Journal article, 2021)Natural sounds, and bird song in particular, play a key role in building and maintaining our connection with nature, but widespread declines in bird populations mean that the acoustic properties of natural soundscapes may ... -
Chasing the bird: 3D acoustic tracking of aerial flight displays with a minimal planar microphone array
Dutilleux, Guillaume Joseph Antonin; Sandercock, Brett Kevin; Kålås, John Atle (Peer reviewed; Journal article, 2023)Tracking the flight patterns of birds and bats in three-dimensional space is central to key questions in evolutionary ecology but remains a difficult technical challenge. For example, complex aerial flight displays are ... -
Decomposing the spatial and temporal effects of climate on bird populations in northern European mountains
Bradter, Ute; Johnston, Alison; Hochachka, Wesley M.; Soultan, Alaaeldin; Brommer, Jon E.; Gaget, Elie; Kålås, John Atle; Lehikoinen, Aleksi; Lindström, Åke; Piirainen, Sirke; Pavòn-Jordàn, Diego; Pärt, Tomas; Øien, Ingar Jostein; Sandercock, Brett (Peer reviewed; Journal article, 2022)The relationships between species abundance or occurrence versus spatial variation in climate are commonly used in species distribution models (SDMs) to forecast future distributions. Under “space-for-time-substitution”, ... -
Heterogeneity among species and community dynamics – Norwegian bird communities as a case study
Solbu, Erik Blystad; Diserud, Ola Håvard; Kålås, John Atle; Engen, Steinar (Journal article; Peer reviewed, 2018)We have in this study analysed bird communities across Norway with a heterogeneous species abundance model, where dynamical parameters can vary among species. Similarity in community composition over time, used as a measure ... -
Louping-ill virus serosurvey of willow ptarmigan (Lagopus Lagopus Lagopus) in Norway
Ytrehus, Bjørnar; Rocchi, Mara; Brandsegg, Hege; Turnbull, Dylan; Miller, Andrea L.; Pedersen, Hans Christian; Kålås, John Atle; Nilsen, Erlend Birkeland (Peer reviewed; Journal article, 2021)In Norway, the Willow Ptarmigan (Lagopus lagopus lagopus) is experiencing population declines and is nationally Red Listed as Near Threatened. Although disease has not generally been regarded as an important factor behind ... -

Gjershaug, Jan Ove; Brøseth, Henrik; Kleven, Oddmund; Kålås, John Atle; Mattisson, Jenny; Tovmo, Mari (Journal article; Peer reviewed, 2018)Capsule: A description of the methods used for monitoring the Golden Eagle Aquila chrysaetos in Norway Aims: To provide a comprehensive description of monitoring methods. Methods: The intensive monitoring of the Golden ... -
Short‑lived species move uphill faster under climate change
Couet, Joséphine; Marjakangas, Emma‑Liina; Santangeli, Andrea; Kålås, John Atle; Lindström, Åke; Lehikoinen, Aleksi (Peer reviewed; Journal article, 2022)Climate change is pushing species ranges and abundances towards the poles and mountain tops. Although many studies have documented local altitudinal shifts, knowledge of general patterns at a large spatial scale, such as ... -
