TL;DR: These rapid changes in terrestrial, freshwater, and marine systems, presage changes at lower latitudes that will affect natural resources, food production, and future climate buffering, and highlight areas of ecological research that deserve priority as the Arctic continues to warm.
Journal ArticleDOI

TL;DR: The usefulness of the vulnerability framework is illustrated through three case studies: the tropical southern Yucatán, the arid Yaqui Valley of northwest Mexico, and the pan-Arctic.

TL;DR: In this paper, a generalized vulnerability framework was used to structure an interdisciplinary and intercultural examination of factors that influence the ways in which reindeer pastoralism in Finnmark (northern Norway) may be affected by climate change.
Journal ArticleDOI
Photosynthesis by Isolated Protoplasts, Protoplast Extracts, and Chloroplasts of Wheat: Influence of Orthophosphate, Pyrophosphate, and Adenylates
TL;DR: In order to obtain maximum rates of photosynthesis and minimum induction time, NaHCO(3) and chelating agents, EDTA or PPi (+ATP), are required in the chloroplast isolation, resuspension and assay medium.
Journal ArticleDOI
Circadian organization in reindeer
Bob van Oort,Nicholas J. C. Tyler,Menno P. Gerkema,Lars P. Folkow,Arnoldus Schytte Blix,Karl-Arne Stokkan +5 more
TL;DR: The continuous lighting conditions of summer and of winter at high latitudes cause a loss in daily rhythmic activity in reindeer living far above the Arctic Circle, suggesting that this seasonal absence of circadian rhythmicity may be a ubiquitous trait among resident polar vertebrates.
