• Changes in the adult sex ratio of six duck species breeding populations over two decades 

  Homolková, Monika; Musil, Petr; Pavon-Jordan, Diego; Gajdošová, Dorota; Musilová, Zuzana; Neužilová, Šárka; Zouhar, Jan (Peer reviewed; Journal article, 2024)

  Despite all efforts, long-term changes in the adult sex ratios of breeding duck populations are still unclear; this uncertainty is especially true for male-bias populations, which are often under the scrutiny of researchers ...

• A specialist predator in a food web with cyclic alternative prey:The gyrfalcon-ptarmigan case revisited 

  Kleiven, Eivind Flittie; Johansen, Kenneth; Ims, Rolf Anker; Soininen, Eeva M; Oksanen, Lauri Kalervo; Oksanen, Tarja Maarit; Jacobsen, Karl-Otto; Østlyngen, Arve (Peer reviewed; Journal article, 2025)

  1. Population dynamics of specialist predators are tightly linked to their main prey and can in simple food webs lead to complex predator–prey interactions (e.g. predator–prey cycles). However, the strength of these ...

• Climatic variation affects seasonal survival of an alpine bird species 

  Eriksen, Lasse Frost; Ringsby, Thor Harald; Israelsen, Markus Fjellstad; Moa, Pål Fossland; Grøtan, Vidar; Nilsen, Erlend Birkeland (Peer reviewed; Journal article, 2025)

  Mountains are particularly exposed to climate change, and empirical studies haveshown that montane bird species are highly sensitive to the ongoing changes. Modellingmortality risks under climatic variation will give insight ...

• Flexibility in female spatiotemporal behavioral tactics to counter infanticide risk during the mating season 

  Heeres, Rick W.; Leclerc, Martin; Frank, Shane; Kopatz, Alexander; Pelletier, Fanie; Zedrosser, Andreas (Peer reviewed, 2025)

  Background Parental care is exclusively provided by females in most mammals, and mothers use several spatiotemporal behavioral tactics to minimize risks to ofspring and to enhance ftness of both the mother and ofspring. ...

• The value of hyperspectral UAV imagery in characterizing tundra vegetation 

  Putkiranta, Pauli; Räsänen, Tuomas Aleksi; Korpelainen, Pasi; Erlandsson, Rasmus; Kolari, Tiina H.M.; Pang, Yuwen; Villoslada, Miguel; Wolff, Franziska; Kumpula, Timo; Virtanen, Tarmo (Peer reviewed; Journal article, 2024)

  The fine-scale spatial heterogeneity of low-growth Arctic tundra landscapes necessitates the use of high- spatialresolution remote sensing data for accurate detection of vegetation patterns. While multispectral satellite ...
