Summary: The study indicates that increased seasonal productivity leads to earlier autumn senescence of temperate trees, which is in agreement with observations from free-air CO2 enrichment experiments.

Summary: Many invasive and some native tree species in North America exhibit strong allelopathic effects that may contribute to their local dominance. Pyrogenic carbon (PyC) produced by the incomplete combustion of organic matter is widespread in forest soils and has sorptive properties that can reduce the bioavailability of allelochemicals. This study investigated the potential of biochar (BC) produced by pyrolysis to reduce the allelopathic effects of black walnut and Norway maple.

Summary: This study describes the growth of trees in the channel of Sinking Creek in the Appalachian Mountains and tests the hypothesis that low-flow periods in the past have allowed tree-seedling establishment. Results show that sycamores established during periods of low precipitation and are located at the upstream end of bars.

Summary: Photodegradation contributes to similar leaf litter mass loss rates in mesic environments and drylands, despite water limitations in the latter. Our study in the Southern Appalachian Mountains showed that during the non-growing season, exposure to maximum solar radiation led to decreased proportions of oxidized lignin relative to other carbon compounds in leaf litter. This phenomenon was particularly strong on south-facing slopes with higher solar radiation levels.

Summary: In temperate forests, fungi play a crucial role in the decomposition of leaf litter. However, their influence on the chemical changes in leaf litter remains poorly understood. This study aimed to determine the main factors driving leaf litter chemical transformation during decomposition by conducting a long-term transplantation experiment.

Summary: Leaf optical properties play a key role in interpreting remote sensing data on vegetation canopy structure and functions. By studying the seasonal patterns of leaf optical properties in different tree species, we can better understand the growth and development of vegetation. The reflectance and transmittance spectra of leaves exhibit distinct seasonal changes.

Summary: Studies have shown that the chemistry of seasonal litterfall is influenced by dominant plant species, with different chemical properties observed between wet and dry seasons. These findings suggest that shifts in dominant plant species and seasonality may alter litterfall chemistry, leading to changes in carbon and nutrient fluxes in tropical riparian ecosystems.

Summary: The study revealed that severe drought does not affect the onset of autumn leaf senescence in temperate deciduous tree species, despite high mortality in saplings and advanced loss of canopy greenness in mature trees. There were no significant differences observed among different tree species.

Summary: Considering the important role of litter quality in soil processes, litter species diversity may be a key determinant of many ecosystem functions, including carbon (C) sequestration. Laboratory incubation studies can help identify the traits of litter that affect soil microbial CO2 production, and our research found that different litter species have varying effects on soil CO2 production rates over time.

Summary: The study in China found that leaf-out variation decreases towards higher latitudes and shows an increasing trend over time. The spatial pattern of leaf-out variation is likely influenced by increased heat requirements and temperature sensitivity, while the temporal pattern may be related to higher average air temperatures and leaf-out requirements during the later period.

Summary: Biological invasions, particularly of woody species, can have cross-ecosystem effects, especially in meta-ecosystems like stream-riparian forests. The invasion of N-fixing species in temperate deciduous broadleaf forests can lead to changes in stream ecosystem functioning, affecting water quality, flow, and litter input characteristics. Different traits of native and invasive tree species, environmental conditions, and the extent of invasion can influence the magnitude of these effects on streams, potentially jeopardizing multiple ecosystem services.

Summary: This study assessed leaf gas exchange responses in young olive trees to prolonged elevated temperature, as well as additional leaf traits such as stomatal density and size, and whether photosynthetic acclimation to temperature was apparent. Results showed that while parameters like Amax, gs, and chlorophyll fluorescence were little affected by heating, leaf transpiration was higher in heated leaves, leading to reduced water-use efficiency. Thermal acclimation was suggested by higher Amax values in leaves grown under the same temperature level they were measured at.

Summary: Individual tree species can affect soil properties underground to promote the decomposition of their own litter. However, studies have shown that diverse overstorey plant species create a more favorable microenvironment for litter decomposition than canopies composed of a single species. This study found that the origin of the litter species had a more significant impact on decomposition rates than the microenvironment.

Summary: Microplastics are retained in sludge in wastewater treatment plants, where they harbor diverse bacterial communities including those associated with bioflocculation. Effluent microplastics have higher abundances of bacteria linked to plastic breakdown and some potentially pathogenic taxa compared to influent microplastics. WWTPs can modify the microplastic-associated bacterial assemblages, potentially influencing the fate of microplastics in the environment.
