Summary: Previous studies have shown that the impacts of harvest on stream chemistry in deciduous forests with seasonal snow cover vary and may take different recovery times. In this study, we investigated the interactive effects of forest harvesting with regional and global environmental changes on stream solute concentrations and other parameters. The results showed that the impacts of harvest on stream chemistry were greatest in clearcut areas, moderate in selection cut areas, and least in shelterwood cut areas. The impacts typically lasted for one to six years, although some solutes were impacted for the entire 21 year post-harvest period. Different solutes showed different response patterns, which were consistent with expected changes in nutrient demand, sources, and transport due to harvesting. Comparing harvest impacts to long-term climate change and acidification recovery revealed antagonistic or synergistic effects depending on the solute. These findings highlight the importance of long-term monitoring to accurately understand the consequences of forest harvesting practices in the face of environmental change.

Summary: The oak-pine forests in the U.S. Central Hardwood Region are recovering from past exploitation and experiencing rapid succession changes. A study on red oak borer outbreaks and their interaction with climate change revealed that succession plays a more crucial role than climate effects and insect disturbances in predicting regional species composition changes. The modeling approach used in the study improved the realism of simulating insect disturbances and provided insights for decision-making in forest management plans.

Summary: Fertilization of young spruce plantations acts as a strong filter for ground beetle assemblages, leading to functionally homogeneous communities in the short term without changes in species richness. The large-scale functional impoverishment of carabid communities due to fertilization may have negative consequences on system resilience and ecosystem service provision. The establishment of nutrient optimization poses a threat to ground beetle diversity in young conifer plantations, highlighting the risks of introducing more intensive management schemes in heavily managed forest landscapes.

Summary: Precipitation-induced landslides can have significant impacts on insect community properties, but our understanding of post-landslide changes is limited. To address this, we conducted a large-scale field experiment by artificially causing landslides at multiple sites. We found that forest type did not affect the structure of a ground-dwelling beetle community disturbed by a landslide, but did affect an undisturbed community. The structures of landslide and undisturbed communities were completely different, possibly due to harsh environments created by landslides acting as ecological filters.

Summary: The terrestrial carbon sink plays a significant role in slowing down the accumulation of carbon dioxide in the atmosphere. The sensitivity of the atmospheric CO2 growth rate to tropical temperature has changed over the past six decades, with the drivers of this change remaining unidentified. This study examines the cause of this sensitivity change and finds that it is influenced by long-term changes in the magnitude of CO2 growth rate variability and extreme drought-affected areas in tropical Africa, Asia, and semi-arid ecosystems.

Summary: Climate change has significant impacts on terrestrial ecosystems, but little is known about its effects on soil communities, particularly their resistance to changes in temperature and precipitation. This study examined the impact of predicted reductions in rainfall on soil food webs using nematodes as bioindicators, and found that rainfall reduction had negative effects on nematode abundance, community composition, and indicators of soil food web structure. These results suggest a low resistance of soil food webs to climate change-induced rainfall reductions.

Summary: Northern peatlands are important carbon stores and major sources of atmospheric methane. Existing models fail to accurately represent carbon emissions from peatlands, in part due to inadequate representation of the hydrologic cycle and microtopography. This study highlights the significant influence of microtopographic parameters on carbon cycling and suggests incorporating these parameters into earth system models.

Summary: Warming is found to exponentially increase plant-available ammonium and phosphate in a peatland ecosystem, with no effect from elevated CO2 levels. The dynamics of nutrient availability are influenced by peat depth and microtopography. Future predictions of peatland nutrient availability should take into account dynamic changes in nutrient acquisition by plants and microbes, as well as peat depth and microtopography.

Summary: The sensitivity of peatlands to climate warming varies depending on the timing of summer warming, with early warming leading to increased CO2 uptake and later warming resulting in decreased uptake. Peatlands in regions such as central Siberia, where early summer warming occurs, are more likely to continue functioning as net CO2 sinks under warmer climate conditions.

Summary: Soil and atmospheric droughts pose increasing threats to plant survival and productivity worldwide. However, there are conceptual gaps that limit our ability to predict the impacts of drought on ecosystems under climate change. This study introduces the concept of the ecosystem wilting point (psi(EWP)), which integrates the drought response of a plant community across the soil-plant-atmosphere continuum. The findings show that psi(EWP) serves as a threshold defining significant shifts in ecosystem functional state.

Summary: Understanding and quantifying the dynamics and uncertainties of peatland methane (CH4) emissions are crucial for mitigating climate change. The relative contributions of different CH4 emission pathways are highly uncertain, with the ebullition process being particularly uncertain. This study evaluated two model structures and found that the ebullition bubble growth volume threshold approach provided better simulations of CH4 emissions and underlying mechanisms. Constraining the model with both CH4 flux and concentration data significantly reduced uncertainties in modeled CH4 concentration profiles.

Summary: This study utilized high-resolution minirhizotron technology in a forested bog to investigate the dynamics of plant fine roots and fungal mycelium, revealing that ericaceous shrub roots and ectomycorrhizal fungal rhizomorphs were more abundant in warmer and drier peat, while tree fine roots, ectomycorrhizas, and dark-colored fungal hyphae were more prevalent in colder, wetter peat. The warmer end of the experimental temperature gradient extended the belowground active season for both plant roots and fungi by 62 days, impacting belowground carbon, water, and nutrient fluxes.
