Summary: The study revealed that peatlands intersected by seismic lines tend to have an earlier seasonal peak, with vegetation communities showing a stronger relationship to greenness and gross primary production in disturbed areas compared to undisturbed areas. This change in understory vegetation results in greater CO2 uptake in disturbed areas.

Summary: Research in treed bogs of Alberta shows that the recovery of historic seismic lines is slow and does not follow expected successional trajectories. Differences in plant species and functional traits composition were observed on seismic lines compared to adjacent treed bogs, with seismic lines having primarily shorter species and abundant low ericaceous shrubs. Understanding the mechanisms behind these differences can help inform restoration and mitigation measures needed for seismic line recovery in the future.

Summary: This study reveals that changes in vegetation condition in response to climate warming in northern high latitudes are closely linked to changes in surface water cover, explaining the contrasting trajectories of ecosystem dynamics. This has significant implications for ecosystem functioning, carbon sequestration, and feedbacks to the climate system.

Summary: This study examined the invasibility of different alpine plant community types by Scots pine and found that herbivore exclusion and vegetation removal can promote pine seedling establishment and growth. Microclimate factors had minimal effects on pine seedling establishment and performance in alpine tundra ecosystems.

Summary: The quality of container-grown seedlings is influenced by the air and water properties of the substrate. Increase in substrate density leads to changes in air and water properties within containers, affecting different tree species in varying degrees. Precise control over water dosage during irrigation can reduce water consumption and improve seedling growth for certain species.

Summary: Climate-mediated drying can reduce gross primary productivity (GPP) and increase ecosystem respiration (ER) in shallow Boreal Shield peatlands, making them vulnerable to a weaker carbon sink function and potential net carbon loss.

Summary: Woody encroachment in southern African savanna has been partially attributed to elevated CO2 concentrations, which promote the growth of C-3 trees. However, the effects on C-4 grasses are less significant. Suitable growth conditions are crucial for the realization of the effects of elevated CO2.

Summary: The recruitment of arid-zone plant species is highly impacted by seed dormancy, temperature, and water stress. Understanding the vulnerability of the transition from seeds to established seedlings is crucial, as increased temperature and water stress can lead to recruitment failure.

Summary: The study indicates that regeneration of white spruce seedlings in water-limited areas is sensitive to both light availability and local competition, with competition exacerbating the effects of drought on seedlings.

Summary: The study found that earlywood and latewood widths in boreal and Mediterranean European forests respond differently to climate, constrained by allometric relationships. In cold, dry Mediterranean sites, there is a high coupling between earlywood and latewood widths, with latewood width being very responsive to climate and atmospheric patterns.

Summary: This study examines the influence of root-associated microbiota on the growth of boreal tree species. The observed plant-soil feedbacks mirror the successional patterns found in boreal forests, suggesting a possible contribution of soil microbiota to the successional progression. Species-specific ectomycorrhizal fungi and a few bacteria rather than fungal plant pathogens or oomycetes seem to drive the feedbacks by promoting seedling growth in heterospecific soils.

Summary: The study found that the boreal peatland dominated by Sphagnum moss had higher trophic diversity of nematodes and larger predatory nematodes compared to the Carex-dominated peatland. These observations provide important baseline information for understanding the dynamics of peatland soil food webs and their implications for carbon and nutrient dynamics.

Summary: The increase in frequency, intensity, and duration of drought events affects forested ecosystems by causing trees to adjust stomatal conductance to maximize the trade-off between carbon gains and water losses. This study found that a decline in growth rates of black spruce and jack pine in an exceptionally dry period from 1988 to 1992 was related to physiological adjustments of trees to drought. Isotopic signals were linked to climate moisture index, vapor pressure deficit, and annual snowfall amount, impacting tree growth and physiological responses.

Summary: This study examined the field performance of Norway spruce container seedlings planted from May to July 2021 in different regeneration sites in Finland. The planting period and packaging and storage methods of the seedlings were found to be the most important factors affecting drought risk. Other factors such as previous-year height of the seedlings, pre-planting precipitation, and average temperature after planting also influenced the risk of drought damage. Optimizing operational choices and measures can help ensure the development of dense and fast-growing young Norway spruce forests in a warming climate.

Summary: The study found that temperature did not affect the rate of C-13 assimilation into shoots, but higher temperatures decreased the fraction of assimilated C that was allocated belowground by vascular plants. Sedges assimilated CO2 faster into their shoot biomass and allocated more of the assimilated C-13 belowground than shrubs. However, sedges retained this belowground allocated C better than shrubs, leading to lower C-13 in soil respiration measured under sedges.

Summary: The risk to vegetation and peat decomposition from alkaline ash inputs after peatland wildfire is poorly understood. This study found that ash inputs were insufficient to increase pH of the acidic peatland soil, and a significant amount of ash was required to cause a noticeable pH increase. The study suggests that elevated soil pH from ash input may be transient rather than long term.

Summary: Shrubs in the Arctic are expanding due to warmer temperatures, leading to increases in biomass, stature, and cover. The growth of these shrubs is generally associated with summer temperature, but with varying responses to precipitation. It is important to consider topographic gradients and long-term variability when studying climate-growth associations in Arctic shrubs.
