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 ... -

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) -
Kjøttfekalvers tilvekst på utmarksbeite : effekt av rase og beitekvalitet
Heim, Kjersti (Master thesis, 2019)I Norge har antall ammekyr økt kraftig det siste tiåret for å dekke den økende innenlandske etterspørselen etter storfekjøtt. Våre store uutnytta utmarksbeiteressurser gir muligheter for ekstensiv kjøttproduksjon på ... -
Lamb performance on island pastures in Northern Norway
Lind, Vibeke; Holand, Øystein; Haugen, Finn-Arne; Steinheim, Geir (Peer reviewed; Journal article, 2020)The Norwegian sheep industry is based on utilization of “free” rangeland pasture resources. Use of mountain pastures is dominating, with about two million sheep grazing these pastures during summer. Regional challenges ... -
Long-Term Increase in Aboveground Carbon Stocks Following Exclusion of Grazers and Forest Establishment in an Alpine Ecosystem

Nutritional and anti-nutritional quality of range vegetation in southern Ethiopia and supplementary values of selected browse leaves to goats
Woldemariam, Aster Abebe (PhD Thesis;2010:51, Doctoral thesis, 2010)Livestock are reared in all agroecological zones of Ethiopia under various production systems. Goats, although found in all agroecological zones, are popular in the drier environments since they adapt well in harsh condition ... -
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 ... -
