Abstract The Spruce and Peatland Responses Under Changing Environments (SPRUCE) experiment has operated five whole‐ecosystem warming manipulations (+0, +2.25, +4.5, +6.75, +9°C) with paired ambient elevated CO 2 atmospheres (eCO , +500 ppm) for 8 full calendar years (since August 2015). We tracked shrub‐layer vegetation responses to the treatments using annual destructive plot sampling.

The rapid expansion of remote sensing provides recent and developed advances in monitoring wetlands. Integrating cloud computing with these techniques has been identified as an effective tool, especially for dealing heterogeneous datasets. In this study, we conducted a systematic literature review (SLR) to determine the current state-of-the-art knowledge integrating results SLR revealed that platform-as-a-service was only service model implemented practice wetland monitoring. Remote applications included prediction, time series analysis, mapping, classification, change detection. Only 51% reviewed literature, focused on regional scale, used satellite data. Additionally, found technologies are not integrated enough benefit from their potential Despite gaps, analysis economic benefits could be achieved by implementing To address gaps pave way further research, propose Internet Things (IoT) monitor wetlands effectively.

Abstract Climate warming and projected increase in summer droughts puts northern peatlands under pressure by subjecting them to a combination of gradual drying extreme weather events. The combined effect those on peatland functions is poorly known. Here, we studied the impact long‐term water level drawdown (WLD) contrasting conditions leaf phenology biomass production ground vegetation boreal peatlands. Data were collected during two growing seasons from WLD experiment including rich poor fen an ombrotrophic bog. Results showed that had strong both area development production, these responses differed between types. In bog, increased plant growth, while fen, reduced growth vegetation. Plant groups their response, as graminoids, shrubs tree seedlings benefited it. addition, adjusted lower WTs, was more responsive short‐term climatic variations. warmer resulted greater maximum earlier peaking index, vascular plants Sphagnum mosses at sites. particular, graminoids benefitted conditions. change towards sites general related observed transition functional type composition arboreal

Peatlands are major natural carbon pool in terrestrial ecosystems globally and essential to a variety of fields, including global ecology, hydrology, ecosystem services. Under the context climate change, management conservation peatlands has become topic international concern. Nevertheless, few studies have yet systematized overall dynamics existing peatland research. In this study, based on an approach integrating bibliometrics literature review, we systematically analyzed research from perspective. Alongside traditional bibliometric analyses (e.g., number publications, impact, hot areas), recent top keywords were found, ‘oil palm’, ‘tropical peatland’, ‘permafrost’, so on. Furthermore, six topics identified: (1) development impacts degradations, (2) history factors formation, (3) chemical element contaminants peatlands, (4) tropical (5) peat adsorption its humic acids, (6) influence ecosystem. addition, review found that adverse consequences degradation change merit greater attention, peatland-mapping techniques suitable for all regions lacking, unified assessment stocks urgently needs be established, spanning countries, reliable system assessing peatland-ecosystem services implemented expeditiously. argued enhanced integration will bridge knowledge gaps facilitate systematic synthesis as complex systems, which is imperative need.
