Abstract. Rapid warming of the arctic terrestrial region has the potential to increase soil decomposition rates and form a carbon-driven feedback to future climate change. For accurate prediction of the role of soil microbes in these processes it will be important to understand the temperature responses of soil bacterial communities and implement them into biogeochemical models. The temperature adaptation of soil bacterial communities for a large part of the Arctic region is unknown. We evaluated the current temperature adaption of soil bacterial communities from 12 sampling sites in the sub- to High Arctic. Temperature adaptation differed substantially between the soil bacterial communities of these sites, with estimates of optimal growth temperature (Topt) ranging between 23.4 {\textpm} 0.5 and 34.1 {\textpm} 3.7 C. We evaluated possible statistical models for the prediction of the temperature adaption of soil bacterial communities based on different climate indices derived from soil temperature records, or on bacterial community composition data. We found that highest daily average soil temperature was the best predictor for the Topt of the soil bacterial communities, increasing 0.63 {\textdegree}C per {\textdegree}C. We found no support for the prediction of temperature adaptation by regression tree analysis based on relative abundance data of most common bacterial species. Increasing summer temperatures will likely increase Topt of soil bacterial communities in the Arctic. Incorporating this mechanism into soil biogeochemical models and combining it with projections of soil temperature will help to reduce uncertainty in assessments of the vulnerability of soil carbon stocks in the Arctic.

We identify three recovery phases. In Phase 1, nitrogen is redistributed from soil organic matter to vegetation, but the ecosystem continues to lose nitrogen because the recovering vegetation cannot take up nitrogen as fast as it is released from soil. In Phase 2, the ecosystem begins re-accumulating nitrogen and converges on a quasi-steady state in which vegetation and soil-microbial processes are in balance. In Phase 3, vegetation and soil-microbial processes remain in balance and the ecosystem slowly re-accumulates the remaining nitrogen. Phase 3 follows a balanced-accumulation trajectory along a continuum of quasi-steady states that approaches the true steady state asymptotically. We examine the effects of three ecosystem properties on recovery: openness of the nitrogen cycle, nitrogen distribution in and turnover between vegetation and soils, and the proportion of nitrogen losses that are in a refractory form. Openness exacerbates Phase 1 nitrogen losses but speeds recovery in Phases 2 and 3. A high fraction of ecosystem nitrogen in vegetation, resulting from nitrogen turnover that is slow in vegetation but fast in soil, exacerbates Phase 1 nitrogen losses but speeds recovery in Phases 2 and 3. A high proportion of nitrogen loss in refractory form mitigates Phase 1 nitrogen losses and speeds recovery in Phases 2 and 3. Application of our conceptual framework requires empirical recognition of the continuum of quasi-steady states constituting the balanced-accumulation trajectory and a distinction between the balanced-accumulation trajectory and the true steady state.}, issn = {1432-9840, 1435-0629}, doi = {10.1007/s10021-020-00542-3}, url = {https://link.springer.com/10.1007/s10021-020-00542-3}, author = {Rastetter, Edward B. and Kling, George W. and Shaver, Gaius R. and Crump, Byron C. and Gough, Laura and Griffin, Kevin L.} } @article {pennock_effects_2021, title = {Effects of increased temperature on arctic slimy sculpin (Cottus cognatus) is mediated by food availability: Implications for climate change}, journal = {Freshwater Biology}, volume = {66}, number = {3}, year = {2021}, month = {mar}, pages = {549{\textendash}561}, keywords = {LTER-ARC, update-2021-02}, issn = {0046-5070, 1365-2427}, doi = {10.1111/fwb.13659}, url = {https://onlinelibrary.wiley.com/doi/10.1111/fwb.13659}, author = {Pennock, Casey A. and Budy, Phaedra and Atkinson, Carla L. and Barrett, Nick} } @article {mclaren_enhanced_2021, title = {Enhanced plant leaf P and unchanged soil P stocks after a quarter century of warming in the arctic tundra}, journal = {Ecosphere}, volume = {12}, number = {11}, year = {2021}, month = {nov}, keywords = {LTER-ARC, update-2021-02}, issn = {2150-8925, 2150-8925}, doi = {10.1002/ecs2.3838}, url = {https://onlinelibrary.wiley.com/doi/10.1002/ecs2.3838}, author = {McLaren, Jennie R. and Buckeridge, Kate M.} } @article {pilla_global_2021, title = {Global data set of long-term summertime vertical temperature profiles in 153 lakes}, journal = {Scientific Data}, volume = {8}, number = {1}, year = {2021}, month = {dec}, pages = {200}, abstract = {Abstract Climate change and other anthropogenic stressors have led to long-term changes in the thermal structure, including surface temperatures, deepwater temperatures, and vertical thermal gradients, in many lakes around the world.

However, herbivores are often absent from modern carbon cycle models, partly because relatively few field studies focus on herbivore impacts on carbon cycling. Our objectives were to quantify the impact of 21 years of large herbivore and large and small herbivore exclusion on carbon cycling during peak growing season in a dry heath tundra community. When herbivores were excluded, we observed a significantly greater leaf area index as well as greater vascular plant abundance. While we did not observe significant differences in deciduous dwarf shrub abundance across treatments, evergreen dwarf shrub abundance was greater where large and small herbivores were excluded. Both foliose and fruticose lichen abundance were higher in the large herbivore, but not the small and large herbivore exclosures. Net ecosystem exchange (NEE) likewise indicated the highest carbon uptake in the exclosure treatments and lowest uptake in the control (CT), suggesting that herbivory decreased the capacity of dry heath tundra to take up carbon. Moreover, our calculated NEE for average light and temperature conditions for July 2017, when our measurements were taken, indicated that the tundra was a carbon source in CT, but was a carbon sink in both exclosure treatments, indicating removal of grazing pressure can change the carbon balance of dry heath tundra.

The physiological mechanisms involved in determining the relationship between the physical and biological environment and the location of treeline are not fully understood. In Northern Alaska, we studied the relationship between temperature and leaf respiration in 36 white spruce ( Picea glauca ) trees, sampling both the upper and lower canopy, to test two research hypotheses. The first hypothesis is that upper canopy leaves, which are more directly coupled to the atmosphere, will experience more challenging environmental conditions and thus have higher respiration rates to facilitate metabolic function. The second hypothesis is that saplings [stems that are 5{\textendash}10cm DBH (diameter at breast height)] will have higher respiration rates than trees (stems >=10cm DBH) since saplings represent the transition from seedlings growing in the more favorable aerodynamic boundary layer, to trees which are fully coupled to the atmosphere but of sufficient size to persist. Respiration did not change with canopy position, however respiration at 25{\textdegree}C was 42\% higher in saplings compared to trees (3.43{\textpm}0.19 vs. 2.41{\textpm}0.14μmolm -2 s -1 ). Furthermore, there were significant differences in the temperature response of respiration, and seedlings reached their maximum respiration rates at 59{\textdegree}C, more than two degrees higher than trees. Our results demonstrate that the respiratory characteristics of white spruce saplings at treeline impose a significant carbon cost that may contribute to their lack of perseverance beyond treeline.

We investigated whether northern tundra ecotypes of E. vaginatum could extend their growing season in response to direct warming and transplanting into southern ecosystems. At the same time, we examined whether southern ecotypes could adjust their growth patterns in order to thrive further north, should they disperse quickly enough. Detailed phenology measurements across three reciprocal transplant gardens over a 2-year period showed that some northern ecotypes were capable of growing for longer when conditions were favourable, but their biomass and growing season length was still shorter than those of the southern ecotype. Southern ecotypes retained large leaf length when transplanted north and mirrored the growing season length better than the others, mainly owing to immediate green-up after snowmelt.

Rainfall contributes to soil saturation, but can also introduce oxygen, causing soil oxidation and altering anoxic conditions. We simulated a rainfall event in soil mesocosms from two dominant tundra types, tussock tundra and wet sedge tundra, to test the impacts of rainfall-induced soil oxidation on microbial communities and their metabolic capacity for anaerobic CH4 production and aerobic respiration following soil oxidation. In both types, rainfall increased total soil O2 concentration, but in tussock tundra there was a 2.5-fold greater increase in soil O2 compared to wet sedge tundra due to differences in soil drainage. Metagenomic and metatranscriptomic analyses found divergent microbial responses to rainfall between tundra types. Active microbial taxa in the tussock tundra community, including bacteria and fungi, responded to rainfall with a decline in gene expression for anaerobic metabolism and a concurrent increase in gene expression for cellular growth. In contrast, the wet sedge tundra community showed no significant changes in microbial gene expression from anaerobic metabolism, fermentation, or methanogenesis following rainfall, despite an initial increase in soil O2 concentration. These results suggest that rainfall induces soil oxidation and enhances aerobic microbial respiration in tussock tundra communities but may not accumulate or remain in wet sedge tundra soils long enough to induce a community-wide shift from anaerobic metabolism. Thus, rainfall may serve only to maintain saturated soil conditions that promote CH4 production in low-lying wet sedge tundra soils across the Arctic.}, keywords = {LTER-ARC, update-2021-02}, issn = {2571-8789}, doi = {10.3390/soilsystems5010017}, url = {https://www.mdpi.com/2571-8789/5/1/17}, author = {Romanowicz, Karl J. and Crump, Byron C. and Kling, George W.} } @article {kropp_shallow_2021, title = {Shallow soils are warmer under trees and tall shrubs across Arctic and Boreal ecosystems}, journal = {Environmental Research Letters}, volume = {16}, number = {1}, year = {2021}, pages = {015001}, abstract = {Abstract 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 lacks the generality necessary to predict soil warming and permafrost stability on a pan-Arctic scale. Here we synthesize shallow soil and air temperature observations with broad spatial and temporal coverage collected across 106 sites representing nine different vegetation types in the permafrost region. We showed ecosystems with tall-statured shrubs and trees (>40 cm) have warmer shallow soils than those with short-statured tundra vegetation when normalized to a constant air temperature. In tree and tall shrub vegetation types, cooler temperatures in the warm season do not lead to cooler mean annual soil temperature indicating that ground thermal regimes in the cold-season rather than the warm-season are most critical for predicting soil warming in ecosystems underlain by permafrost. Our results suggest that the expansion of tall shrubs and trees into tundra regions can amplify shallow soil warming, and could increase the potential for increased seasonal thaw depth and increase soil carbon cycling rates and lead to increased carbon dioxide loss and further permafrost thaw.}, issn = {1748-9326}, doi = {10.1088/1748-9326/abc994}, url = {https://iopscience.iop.org/article/10.1088/1748-9326/abc994}, author = {Kropp, Heather and Loranty, Michael M and Natali, Susan M and Kholodov, Alexander L and Rocha, Adrian V and Myers-Smith, Isla and Abbot, Benjamin W and Abermann, Jakob and Blanc-Betes, Elena and Blok, Daan and Blume-Werry, Gesche and Boike, Julia and Breen, Amy L and Cahoon, Sean M P and Christiansen, Casper T and Douglas, Thomas A and Epstein, Howard E and Frost, Gerald V and Goeckede, Mathias and H{\o}ye, Toke T and Mamet, Steven D and O{\textquoteright}Donnell, Jonathan A and Olefeldt, David and Phoenix, Gareth K and Salmon, Verity G and Sannel, A Britta K and Smith, Sharon L and Sonnentag, Oliver and Vaughn, Lydia Smith and Williams, Mathew and Elberling, Bo and Gough, Laura and Hjort, Jan and Lafleur, Peter M and Euskirchen, Eugenie S and Heijmans, Monique MPD and Humphreys, Elyn R and Iwata, Hiroki and Jones, Benjamin M and Jorgenson, M Torre and Gr{\"u}nberg, Inge and Kim, Yongwon and Laundre, James and Mauritz, Marguerite and Michelsen, Anders and Schaepman-Strub, Gabriela and Tape, Ken D and Ueyama, Masahito and Lee, Bang-Yong and Langley, Kirsty and Lund, Magnus} } @article {parker_shrub_2021, title = {Shrub expansion in the Arctic may induce large-scale carbon losses due to changes in plant-soil interactions}, journal = {Plant and Soil}, volume = {463}, number = {1-2}, year = {2021}, pages = {643{\textendash}651}, abstract = {Abstract Background Tall deciduous shrubs are increasing in range, size and cover across much of the Arctic, a process commonly assumed to increase carbon (C) storage. Major advances in remote sensing have increased our ability to monitor changes aboveground, improving quantification and understanding of arctic greening. However, the vast majority of C in the Arctic is stored in soils, where changes are more uncertain. Scope We present pilot data to argue that shrub expansion will cause changes in rhizosphere processes, including the development of new mycorrhizal associations that have the potential to promote soil C losses that substantially exceed C gains in plant biomass. However, current observations are limited in their spatial extent, and mechanistic understanding is still developing. Extending measurements across different regions and tundra types would greatly increase our ability to predict the biogeochemical consequences of arctic vegetation change, and we present a simple method that would allow such data to be collected. Conclusions Shrub expansion in the Arctic could promote substantial soil C losses that are unlikely to be offset by increases in plant biomass. However, confidence in this prediction is limited by a lack of information on how soil C stocks vary between contrasting Arctic vegetation communities; this needs to be addressed urgently.}, keywords = {LTER-ARC, update-2021-02}, issn = {0032-079X, 1573-5036}, doi = {10.1007/s11104-021-04919-8}, url = {https://link.springer.com/10.1007/s11104-021-04919-8}, author = {Parker, Thomas C. and Thurston, Alana M. and Raundrup, Katrine and Subke, Jens-Arne and Wookey, Philip A. and Hartley, Iain P.} } @article {ARC29071, title = {Solar position confounds the relationship between ecosystem function and vegetation indices derived from solar and photosynthetically active radiation fluxes}, journal = {Agricultural and Forest Meteorology}, volume = {298-299}, year = {2021}, month = {01/2021}, pages = {108291}, issn = {01681923}, doi = {10.1016/j.agrformet.2020.108291}, url = {https://linkinghub.elsevier.com/retrieve/pii/S0168192320303932}, author = {Adrian V Rocha and Rose Appel and M Syndonia Bret-Harte and E.

Of these two groups of DOM photo-products, more studies focus on CO 2 (a greenhouse gas) than on partially oxidized DOM, which is likely a diverse group of compounds with poorly constrained roles in aquatic carbon cycling or biogeochemistry. The objective of this study is to address knowledge gaps on the prevalence, products, and pathways of DOM partial photo-oxidation. Here we traced the photochemical incorporation of isotopically labelled 18 O 2 into DOM isolated from Alaskan Arctic surface waters using high-resolution mass spectrometry. Complete and partial photo-oxidation of DOM was also quantified as CO 2 production and O 2 consumption. The majority of 18 O-containing partial oxidation photo-products were classified as carboxylic rich alicyclic molecules (CRAM) and overlapped in composition with previously reported photo-products known to result from the oxidation of DOM by singlet oxygen. These results support a previously proposed hypothesis that photo-oxidation by singlet oxygen may contribute to the formation of CRAM, a compound class of DOM ubiquitously observed in surface waters. The novel application of an isotopic tracer for oxygen incorporation with a mass balance approach to quantify complete and partial photo-oxidation of DOM revealed that less than one mol of O 2 is required to produce one mol of CO 2 . A sensitivity analysis based on this new knowledge demonstrated that the magnitude of DOM partial photo-oxidation may be underestimated by up to four-fold. Consequently, partial photo-oxidation likely plays a more prominent role in shaping DOM composition in sunlit waters of the Arctic than previously understood. Therefore, partial photo-oxidation should be increasingly incorporated into the experimental framework of studies focused on DOM composition in surface waters.}, keywords = {LTER-ARC, update-2021-02}, issn = {2050-7887, 2050-7895}, doi = {10.1039/C9EM00504H}, url = {http://xlink.rsc.org/?DOI=C9EM00504H}, author = {Ward, Collin P. and Cory, Rose M.} } @article {ARC29074, title = {Aufeis fields as novel groundwater-dependent ecosystems in the arctic cryosphere}, journal = {Limnology and Oceanography}, year = {2020}, month = {10-2020}, issn = {0024-3590}, doi = {10.1002/lno.11626}, url = {https://onlinelibrary.wiley.com/doi/10.1002/lno.11626}, author = {Alexander D Huryn and Michael N.

Yet, aquatic carbon dioxide (CO2) and methane (CH4) flux measurements remain scarce, particularly at high resolution and over long periods of time. Effluxes of methane (CH4) and carbon dioxide (CO2) from Toolik Lake, a deep glacial lake in northern Alaska, were measured for the first time with the direct eddy covariance (EC) flux technique during six ice-free lake periods (2010{\textendash}2015). CO2 flux estimates from the lake (daily average efflux of 16.7 {\textpm} 5.3 mmol m-2 d-1) were in good agreement with earlier estimates from 1975{\textendash}1989 using different methods. CH4 effluxes in 2010{\textendash}2015 (averaging 0.13 {\textpm} 0.06 mmol m-2 d-1) showed an interannual variation that was 4.1 times greater than median diel variations, but mean fluxes were almost one order of magnitude lower than earlier estimates obtained from single water samples in 1990 and 2011{\textendash}2012. The overall global warming potential (GWP) of Toolik Lake is thus governed mostly by CO2 effluxes, contributing 86{\textendash}93\% of the ice-free period GWP of 26{\textendash}90 g CO2,eq m-2. Diel variation in fluxes was also important, with up to a 2-fold (CH4) to 4-fold (CO2) difference between the highest nighttime and lowest daytime effluxes. Within the summer ice-free period, on average, CH4 fluxes increased 2-fold during the first half of the summer, then remained almost constant, whereas CO2 effluxes remained almost constant over the entire summer, ending with a linear increase during the last 1{\textendash}2 weeks of measurements. Due to the cold bottom temperatures of this 26 m deep lake, and the absence of ebullition and episodic flux events, Toolik Lake and other deep glacial lakes are likely not hot spots for greenhouse gas emissions, but they still contribute to the overall GWP of the Arctic.

Since biological N-2 fixation is the major source of biologically available N, the soil N-2-fixing (i.e., diazotrophic) community serves as an essential N supplier to the tundra ecosystem. Recent climate warming has induced deeper permafrost thaw and adversely affected C sequestration, which is modulated by N availability. Therefore, it is crucial to examine the responses of diazotrophic communities to warming across the depths of tundra soils. Herein, we carried out one of the deepest sequencing efforts of nitrogenase gene (nifH) to investigate how 5 years of experimental winter warming affects Alaskan soil diazotrophic community composition and abundance spanning both the organic and mineral layers. Although soil depth had a stronger influence on diazotrophic community composition than warming, warming significantly (P < 0.05) enhanced diazotrophic abundance by 86.3\% and aboveground plant biomass by 25.2\%. Diazotrophic composition in the middle and lower organic layers, detected by nifH sequencing and a microarray-based tool (GeoChip), was markedly altered, with an increase of alpha-diversity. Changes in diazotrophic abundance and composition significantly correlated with soil moisture, soil thaw duration, and plant biomass, as shown by structural equation modeling analyses. Therefore, more abundant diazotrophic communities induced by warming may potentially serve as an important mechanism for supplementing biologically available N in this tundra ecosystem. IMPORTANCE With the likelihood that changes in global climate will adversely affect the soil C reservoir in the northern circumpolar permafrost zone, an understanding of the potential role of diazotrophic communities in enhancing biological N-2 fixation, which constrains both plant production and microbial decomposition in tundra soils, is important in elucidating the responses of soil microbial communities to global climate change. A recent study showed that the composition of the diazotrophic community in a tundra soil exhibited no change under a short-term (1.5-year) winter warming experiment. However, it remains crucial to examine whether the lack of diazotrophic community responses to warming is persistent over a longer time period as a possibly important mechanism in stabilizing tundra soil C. Through a detailed characterization of the effects of winter warming on diazotrophic communities, we showed that a long-term (5-year) winter warming substantially enhanced diazotrophic abundance and altered community composition, though soil depth had a stronger influence on diazotrophic community composition than warming. These changes were best explained by changes in soil moisture, soil thaw duration, and plant biomass. These results provide crucial insights into the potential factors that may impact future C and N availability in tundra regions.}, keywords = {Arctic tundra, carbon, climate warming, diazotrophs, diversity, forest, gene sequencing, increases, LTER-ARC, microbial community, nitrogen-fixation, permafrost, root exudation, soil microbiology, thaw, Tundra}, issn = {2150-7511}, doi = {10.1128/mBio.02521-18}, author = {Feng, Jiajie and Penton, C.

A major effect of global change on carbon cycling is altered exposure of natural organic matter (NOM) to solar radiation, particularly solar UV radiation. In terrestrial and aquatic ecosystems, NOM is degraded by UV and visible radiation, resulting in the emission of carbon dioxide (CO 2 ) and carbon monoxide, as well as a range of products that can be more easily degraded by microbes (photofacilitation). On land, droughts and land-use change can reduce plant cover causing an increase in exposure of plant litter to solar radiation. The altered transport of soil organic matter from terrestrial to aquatic ecosystems also can enhance exposure of NOM to solar radiation. An increase in emission of CO 2 from terrestrial and aquatic ecosystems due to the effects of global warming, such as droughts and thawing of permafrost soils, fuels a positive feedback on global warming. This is also the case for greenhouse gases other than CO 2 , including methane and nitrous oxide, that are emitted from terrestrial and aquatic ecosystems. These trace gases also have indirect or direct impacts on stratospheric ozone concentrations. The interactive effects of UV radiation and climate change greatly alter the fate of synthetic and biological contaminants. Contaminants are degraded or inactivated by direct and indirect photochemical reactions. The balance between direct and indirect photodegradation or photoinactivation of contaminants is likely to change with future changes in stratospheric ozone, and with changes in runoff of coloured dissolved organic matter due to climate and land-use changes.}, keywords = {LTER-ARC, update-2021-02}, issn = {1474-905X, 1474-9092}, doi = {10.1039/c8pp90063a}, url = {http://xlink.rsc.org/?DOI=C8PP90063A}, author = {Sulzberger, B. and Austin, A.
