TL;DR: In this paper, the authors discuss the effects of changing snow cover on the climate, hydrological and ecological systems of the Arctic and other regions through its influence on the surface energy balance (e.g. reflectivity), water balance, thermal regimes, vegetation and trace gas fluxes.

An assessment of restoration of biodiversity in degraded high mountain grazing lands in northern Ethiopia
TL;DR: In this article, the authors assessed the restoration of biodiversity in highly degraded areas in eastern Tigray, northern Ethiopia using area enclosures (AEs) and assessed whether the differences in biodiversity between AEs and open management schemes and time of land abandonment influenced diversity of plant life forms.
Journal ArticleDOI
Use of indigenous ecological knowledge of the Maasai pastoralists for assessing rangeland biodiversity in Tanzania
TL;DR: In this paper, the effects of grazing and cropping on rangeland biodiversity at macro- and micro-landscape scales in northern Tanzania were assessed using the indigenous ecological knowledge of the Maasai pastoralists and ecological methods.
Journal ArticleDOI

Eigil Reimers,Jonathan E. Colman +1 more
TL;DR: In this paper, the authors address the question of how human activities and infrastructure influence reindeer/caribou behavior and habitat use and review studies based on current methodologies.
Journal ArticleDOI
Do wild reindeer exhibit grazing compensation during insect harassment
Jonathan E. Colman,Christian Pedersen,Dag Ø. Hjermann,Øystein Holand,Stein R. Moe,Eigil Reimers +5 more
TL;DR: The effect of daily insect harassment on activity budgets and grazing intensity had a negative effect on the body weights of adult females and calves, as for most wild ungulates, reduced body weight indicates poor condition and can jeopardize survival, reproduction, and calf recruitment.
