Functional Ecology, EarlyView.Read the free Plain Language Summary for this article on the Journal blog. Abstract The light climate at high latitudes, in particular the extended twilight of winter and the reduced diel variation in light level in midsummer and midwinter, potentially constrains visual function and the synchronisation of temporal organisation in polar species. In this

Functional Ecology, EarlyView.Read the free Plain Language Summary for this article on the Journal blog. Abstract In the plant community with a shrub–grass mosaic, the main types of litter include herbaceous litter and its mixed forms with shrub leaves and stems. However, the quantitative relationship between the litter composition type and the litter decomposition, as well as how ...

Livestock as insurance and social status. Evidence from reindeer herding in Norway [PDF]
The theory of livestock as a buffer stock predicts that agropastoralists facing substantial risks typically will use liquid assets, such as livestock, for self-insurance to smooth consumption.

Radiocesium metabolism in reindeer
Rangifer, 1990 Abstract: Early in the era of atmospheric nuclear weapon tests, the reindeer was found to be an interesting animal concerning the transfer of environmental radioactive contaminants to man via the production of contaminated reindeer meat. The reason for the high transfer factors for some radionuclides is the feeding habits of the reindeer with a ...

Journal of Ecology, EarlyView.In nine grassland sites in Europe and North America, nutrient addition caused a larger relative decline in non‐vascular plant (NVP) than vascular plant species richness. Hence, not accounting for NVPs can lead to underestimation of losses in plant diversity in response to continued nutrient pollution of grasslands.

Impact of soil scarification on reindeer pastures
Rangifer, 1990 During recent years, soil scarification has become a standard procedure for improving seed beds after logging. Around 57 000 ha were treated, primarily through harrowing and ploughing, in the counties of Vâsterbotten and Norbotten during 1985.

The history of reindeer in Iceland and reindeer study 1979 - 1981
Rangifer, 1984 <p>This report deals with the history of reindeer in Iceland and reindeer study in East Iceland in the years 1979 - 1981. The study included about half of the Icelandic reindeer population, i.e. that part of it affected by the proposed Austurlandsvirkjun hydro-electric power scheme.

WildWing: An open‐source, autonomous and affordable UAS for animal behaviour video monitoring
Methods in Ecology and Evolution, EarlyView.Abstract Drones have become invaluable tools for studying animal behaviour in the wild, enabling researchers to collect aerial video data of group‐living animals. However, manually piloting drones to track animal groups consistently is challenging due to complex factors such as terrain, vegetation, group spread and movement patterns. The variability in
