TL;DR: In this paper, a consensus is emerging that the underlying causes and future dynamics of so-called Arctic greening and browning trends are more complex, variable and inherently scale-dependent than previously thought.
Journal ArticleDOI
Eighteen years of ecological monitoring reveals multiple lines of evidence for tundra vegetation change
Isla H. Myers-Smith,Meagan M. Grabowski,Haydn J.D. Thomas,Sandra Angers-Blondin,Gergana N. Daskalova,Anne D. Bjorkman,Anne D. Bjorkman,Andrew M. Cunliffe,Jakob J. Assmann,Joseph S. Boyle,Edward McLeod,Samuel McLeod,Ricky Joe,Paden Lennie,Deon Arey,Richard R. Gordon,Cameron D. Eckert +16 more
TL;DR: In this paper, the authors present the findings of a collaboration between government scientists, local people, park rangers, and academic researchers that provide insights into changes in plant composition, phenology, and growth over 18 years on Qikiqtaruk-Herschel Island, Canada.
Journal ArticleDOI
Vegetation monitoring using multispectral sensors — best practices and lessons learned from high latitudes
TL;DR: In this article, a compact multispectral drone sensors capture high-level information from the UAVs and associated sensors for high-quality UAV communications and data collection.
Journal ArticleDOI
Local snow melt and temperature-but not regional sea ice-explain variation in spring phenology in coastal Arctic tundra.

TL;DR: Tundra vegetation responses to global change are more complex than a direct response to warming and the importance of snow melt as a local driver of tundra spring phenology is emphasized.
Journal ArticleDOI

TL;DR: A literature review of 109 papers studying 129 taxa finds that all five criteria that all need to be met to demonstrate that temperature-mediated trophic asynchrony poses a growing risk to consumers are not met.
