High variation in the surface extent of freshwater ponds creates dynamic Arctic tundra landscapes in the lowlands of Eastern Siberia
Greenhouse gas emissions from Arctic tundra ponds and permafrost thaw provide important positive feedbacks to global warming. However, a high landscape heterogeneity and small size of ponds make it challenging to assess trends in surface water extent and associated carbon and energy fluxes, especially in the understudied Eastern Siberian tundra. Here, we show that surface water extent in these landscapes can be highly dynamic, shaped by small-sca…
Summer drought weakens land surface cooling of tundra vegetation
Siberia experienced a prolonged heatwave in the spring of 2020, resulting in extreme summer drought and major wildfires in the North-Eastern Siberian lowland tundra. In the Arctic tundra, plants play a key role in regulating the summer land surface energy budget by contributing to land surface cooling through evapotranspiration. Yet we know little about how drought conditions impact land surface cooling by tundra plant communities, potentially co…
Mid-summer snow-free albedo across the Arctic tundra was mostly stable or increased over the past two decades
Arctic vegetation changes, such as increasing shrub-cover, are expected to accelerate climate warming through increased absorption of incoming radiation and corresponding decrease in summer shortwave albedo. Here we analyze mid-summer shortwave land-surface albedo and its change across the pan-Arctic region based on MODerate resolution Imaging Spectroradiometer satellite observations over the past two decades (2000–2021). In contrast to expectati…
Shallow soils are warmer under trees and tall shrubs across Arctic and Boreal ecosystems
Soils are warming as air temperatures rise across the Arctic and Boreal region concurrent with the expansion of tall-statured shrubs and trees in the tundra. Changes in vegetation structure and function are expected to alter soil thermal regimes, thereby modifying climate feedbacks related to permafrost thaw and carbon cycling. However, current understanding of vegetation impacts on soil temperature is limited to local or regional scales and lack…
There are new species’
Climate change, nutrient pollution, land conversion, overexploitation, and invasive species and diseases – the ‘big five’ global drivers of ecosystem change – are altering biodiversity in the Arctic. Changes in biodiversity have implications for local people since they depend on biodiversity for their traditional activities. Remote Arctic areas lack scientific records of biodiversity status and trends. Indigenous knowledge (IK) can help fill in t…
Genomics meets remote sensing in global change studies
Although the monitoring and prediction of ecosystem dynamics under global change have been extensively assessed, large gaps remain in our knowledge, including a need for concepts in rapid evolution and phenotypic plasticity, and a lack of large-scale and long-term monitoring. Recent genomic studies using the model species Arabidopsis predict that plastic and evolutionary changes in phenology may affect plant reproduction. We propose that three ge…
Integrative research efforts at the boundary of biodiversity and global change research
To fish or not to fish?’
This paper assesses the vulnerability of Arctic fishing communities. We hypothesise that climate change related trends, such as increasing temperature and altered seasonality, and shocks, such as the breakdown of the Soviet Union or new fishing regulations, increase vulnerability of local Arctic peoples and compromise the sustainability of their livelihoods. Research shows that over recent decades local people have observed environmental changes …
The response of Arctic vegetation to the summer climate
Recently observed Arctic greening trends from normalized difference vegetation index (NDVI) data suggest that shrub growth is increasing in response to increasing summer temperature. An increase in shrub cover is expected to decrease summer albedo and thus positively feed back to climate warming. However, it is unknown how albedo and NDVI are affected by shrub cover and inter-annual variations in the summer climate. Here, we examine the relations…
Shrub expansion in tundra ecosystems
Recent research using repeat photography, long-term ecological monitoring and dendrochronology has documented shrub expansion in arctic, high-latitude and alpine tundra ecosystems. Here, we (1) synthesize these findings, (2) present a conceptual framework that identifies mechanisms and constraints on shrub increase, (3) explore causes, feedbacks and implications of the increased shrub cover in tundra ecosystems, and (4) address potential lines of…
