Summary: This study investigated the legacy effects of former plant species on soil carbon and nitrogen distribution after prescribed burning. The results showed that different vegetation patch types responded differently to fire, with legume species and biocrusts showing the most distinct soil differences. After burning, total carbon and nitrogen, as well as carbon and nitrogen in sand, decreased in the 0-5 cm soil layer, while carbon in silt, as well as nitrogen in clay and silt, increased with soil depth.

Summary: This study systematically examined the nitrate and phosphate uptake response of two halotolerant strains of Chlorella vulgaris under different carbon, nitrogen, and phosphorus supply regimes. It was found that changes in carbon supply significantly influenced the uptake of nitrogen and phosphorus by the two strains. This investigation provides clear evidence for the role of supply regimes in nutrient uptake management in microalgae, as well as the significance of carbon supply in nitrogen and phosphorus uptake.

Summary: This study found that agricultural land use has a negative impact on the taxonomic and functional diversity of soil bacteria. Actinobacteria had a higher relative abundance in abandoned fields. The levels of carbon, nitrogen, and ammonium showed strong negative correlations with taxonomic diversity indices, and abandoned fields had a greater number of operational taxonomic units. Functional analysis revealed that soil management significantly affected functions such as cellulolysis and ligninolysis. In conclusion, keeping land fallow for more than 5 years and monitoring carbon, nitrogen, and phosphorus levels are practical approaches for restoring taxonomic diversity of soil bacteria.

Summary: Nitrogen dynamic is a crucial factor in N-limited terrestrial ecosystems' response to climate change. In this study, the partitioning of N in a grassland heath was studied, along with the impact of multiple climate change factors on long-term N retention. After 6 years, it was observed that the majority of the applied N-15 was stabilized in the soil, while the plant compartment and microbial biomass retained a small proportion. The results suggest that N retention in this ecosystem is moderate compared to similar studies in forest ecosystems.

Summary: Thinning in even-aged forest management has been shown to increase concentrations of soil nitrate, total P, and available P, without affecting soil total N and ammonium. Thinning stimulates soil microbial activities, enhances N and P cycling, and varies in its effects depending on climates and forest biomes. Overall, thinning promotes forest soil N and P cycling, contributing to improved soil fertility.

Summary: The aim of this study was to identify the parameters that affect the nitrogen isotope ratio (δN-15) in temperate and boreal forest soils. Two types of δN-15 patterns were identified: type D soils showed a decreasing δN-15 in the mineral soil with depth, while type C soils showed a constant δN-15 throughout the soil profile. Type D soils had higher δN-15 in the organic layer and upper mineral soil, lower atmospheric N deposition, and higher phosphorus concentration than type C soils. The δN-15 of the organic layer was positively correlated with latitude and negatively correlated with mean annual temperature and atmospheric N deposition across Europe.

Summary: The study aims to investigate the effects of altered nutrient availability on phosphorus fluxes in forest soils and examine the variations in response at sites with different phosphorus statuses. The results show that phosphorus fluxes are highly variable and the response to nitrogen and phosphorus addition differs between sites. Therefore, the factors determining phosphorus translocation in forest soils under altered nutrient availability are the spatio-temporal patterns of preferential flow pathways in soil columns and the phosphorus nutrition strategy of the ecosystem.

Summary: Livestock grazing abandonment has important effects on the overall ecosystem function, including on specific bacterial taxa in mountain grasslands. This study evaluated the behavior of bacterial communities in response to short and long-term grazing abandonment, and linked these responses to changes in ecosystem functions such as primary production, biodiversity, carbon stocks, and soil fertility. The study found that the overall composition of soil bacterial communities changed significantly between long-term abandoned grassland areas and grazed or short-term abandoned areas. It also identified specific bacterial taxa that could serve as indicators of grazing abandonment. The study highlights the importance of assessing bacterial community responses to livestock abandonment in mountain grasslands as early warning signs of changes in ecosystem functions.

Summary: Fire danger analysis is crucial for landscape planning, especially in vulnerable areas like the wildland-urban interface (WUI). This study aims to investigate how fuel characteristics can predict burn severity in different WUI typologies based on nearby building density. 23 wildfires across Southern Europe were selected, with distinctions made between non WUI areas, isolated, scattered, dense, and very dense WUIs. Through spatial analysis of burn severity and fuel metrics using satellite imagery, the study found that burn severity is lower in clustered WUIs, and vegetation biophysical properties have the highest influence on burn severity in all WUI typologies. The study also revealed that burn severity is less predictable in dense and very dense WUIs due to their greater complexity and presence of artificial structures.

Summary: Mediterranean ecosystems dominated by maritime pine are experiencing a shift in fire regimes from fuel-limited to drought-driven, resulting in increased wildfire extent, recurrence, and severity. This study examined the effects of fire recurrence and severity on the ecosystem multifunctionality (EMF) of unmanaged maritime pine forests in the western Mediterranean Basin. The results showed that different ecosystem functions responded differently to fire recurrence and severity, and there was an interaction between the two factors. The findings emphasize the importance of an integrative approach to assessing the response of ecosystem functioning to fire regimes.

Summary: Overexploitation, land-use change, and climate warming threaten the conservation of many plant species, including Gentiana lutea. This study examines the effects of burning and clearing on G. lutea populations in the Cantabrian Mountains. Results show a decrease in G. lutea population variables immediately after burning, but a full recovery over the medium term. Clearing has no short-term effects but significantly increases population variables in the medium term. Based on the findings, mechanical clearing is proposed as a suitable management strategy for G. lutea populations in NW Iberian Peninsula.

Summary: The biogeochemical response to different flow conditions within two parallel flow-ways in Everglades Stormwater Treatment Area (STA)-2 was studied. It was found that there was a gradual decrease in the total phosphorus (TP) concentration from inflow to outflow for both emergent aquatic vegetation (EAV) and submerged aquatic vegetation (SAV) dominated systems, with EAV showing a higher reduction rate. Significant increase in TP concentration was observed in the SAV system under no flow condition, possibly due to the production of particulate phosphorus (PP) through various mechanisms.
