Early-life conditions determine the between-individual heterogeneity in plasticity of calving date in reindeer
Paoli, Amelie; Weladji, Robert B.; Holand, Øystein; Kumpula, Jouko (Peer reviewed; Journal article, 2019)Phenotypic plasticity has become a key concept to enhance our ability to understand the adaptive potential of species to track the pace of climate change by allowing a relatively rapid adjustment of life‐history ... -
Historical and social–cultural processes as drivers for genetic structure in Nordic domestic reindeer
Røed, Knut; Kvie, Kjersti; Bårdsen, Bård-Jørgen; Laaksonen, Sauli; Lohi, Hannes; Kumpula, Jouko; Aronsson, Kjell-Åke; Åhman, Birgitta; Våge, Jørn; Holand, Øystein (Peer reviewed; Journal article, 2021)We have analyzed DNA microsatellites and the mitochondrial control region in reindeer from 31 different husbandry areas in Norway, Sweden, and Finland in order to better understand the processes that underlie the genetic ... -
Influence of operational sex ratio and male age on mating competition intensity in reindeer (Rangifer tarandus)
Driscoll, Jeffrey G.; Alo, Franco M.; Paoli, Amélie; Weladji, Robert B.; Holand, Øystein; Kumpula, Jouko; Soveri, Timo (Journal article; Peer reviewed, 2021) -
The onset in spring and the end in autumn of the thermal and vegetative growing season affect calving time and reproductive success in reindeer
Paoli, Amélie; Weladji, Robert B; Holand, Øystein; Kumpula, Jouko (Peer reviewed; Journal article, 2019)A developing trophic mismatch between the peak of energy demands by reproducing animals and the peak of forage availability has caused many species’ reproductive success to decrease. The match–mismatch hypothesis (MMH) is ... -
Potential applications of assisted reproductive technologies (ART) in reindeer (Rangifer tarandus)
Lindeberg, Heli; Nikitkina, E.; Nagy, Sz.; Musidray, A.; Shiryaev, G.; Kumpula, Jouko; Holand, Øystein (Peer reviewed; Journal article, 2021) -
Reproduction of male reindeer (Rangifer tarandus)

Response of reindeer mating time to climatic variability
Paoli, Amelie; Weladji, Robert B.; Holand, Øystein; Kumpula, Jouko (Peer reviewed; Journal article, 2020)Background: The breeding time of many species has changed over the past 2–3 decades in response to climate change. Yet it is a key reproductive trait that afects individual’s parturition time and reproductive success, and ... -
Winter and spring climatic conditions influence timing and synchrony of calving in reindeer
Paoli, Amelie; Weladji, Robert B.; Holand, Øystein; Kumpula, Jouko (Journal article; Peer reviewed, 2018)
