Given the wealth of existing models, it is unclear ... -
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 ... -

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 ... -
Interspecific competition impacts the occupancy and range limits of two ptarmigan species along the elevation gradient in Norway
Mandeville, Caitlin Marie; Finstad, Anders Gravbrøt; Kålås, John Atle; Stokke, Bård Gunnar; Øien, Ingar Jostein; Nilsen, Erlend Birkeland (Peer reviewed; Journal article, 2024)Many mountain species are expected to respond to climate change through upslope shifts of their range limits, but competition may restrict or alter this response. Under traditional range-limit theory, it is expected that ... -
Species distributions models may predict accurately future distributions but poorly how distributions change: A critical perspective on model validation
Piirainen, Sirke; Lehikoinen, Aleksi; Husby, Magne; Kålås, John Atle; Lindström, Åke; Ovaskainen, Otso Tapio (Peer reviewed; Journal article, 2023)Aim: Species distribution models (SDMs) are widely used to make predictions on how species distributions may change as a response to climatic change. To assess the reli-ability of those predictions, they need to be critically ... -

Vriend, Stefan J.G.; Grøtan, Vidar; Gamelon, Marlène; Adriaensen, Frank; Ahola, Markus P.; Álvarez, Elena; Bailey, Liam D.; Barba, Emilio; Bouvier, Jean-Charles; Burgess, Malcolm D.; Bushuev, Andrey; Camacho, Carlos; Canal, David; Charmantier, Anne; Cole, Ella F.; Cusimano, Camillo; Doligez, Blandine F.; Drobniak, Szymon M.; Dubiec, Anna; Eens, Marcel; Eeva, Tapio; Erikstad, Kjell E.; Ferns, Peter N.; Goodenough, Anne E.; Hartley, Ian R.; Hinsley, Shelley A.; Ivankina, Elena; Juškaitis, Rimvydas; Kempenaers, Bart; Kerimov, Anvar B.; Kålås, John Atle; Lavigne, Claire; Leivits, Agu; Mainwaring, Mark C.; Martínez-Padilla, Jesús; Matthysen, Erik; van Oers, Kees; Orell, Markku; Pinxten, Rianne; Reiertsen, Tone Kristin; Rytkönen, Seppo; Senar, Juan Carlos; Sheldon, Ben C.; Sorace, Alberto; Török, János; Vatka, Emma; Visser, Marcel E.; Sæther, Bernt-Erik (Peer reviewed; Journal article, 2022)Identifying the environmental drivers of variation in fitness-related traits is a central objective in ecology and evolutionary biology. Temporal fluctuations of these environmental drivers are often synchronized at large ... -
Terrestrisk naturovervåking i 2013: Markvegetasjon, epifytter, smågnagere og fugl. Sammenfatning av resultater.
Framstad, Erik; Aarrestad, Per Arild; Økland, Tonje; Evju, Marianne; Kålås, John Atle (NINA rapport;1036, Research report, 2014)Overvåkingen i TOV omfatter viktige biologiske komponenter i vanlige boreale og lavalpine økosystemer. Det er forventet at overvåkingsvariablene vil respondere på ulike naturlige og menneskeskapte endringer. Her gis en ...
