Summary: China has been implementing the policy of cultural and tourism industrial integration since 2018. However, the value-added benefits of this policy have not been significant, and the relationship between industrial integration and value added to the tourism value chain has been overlooked. This paper examines the impact of cultural and tourism integration on the tourism value chain and finds that it can enhance the value added through direct and indirect effects, with the direct effect moderated by tourism agglomeration. Additionally, the paper reveals a single-threshold effect, indicating that cultural and tourism integration is only beneficial when it reaches a high level.

Summary: This paper introduces a new approach for information retrieval evaluation metrics that combines upper bound normalization and expected value normalization. Two case studies demonstrate the advantages of this new approach compared to traditional methods. Experimental results show that the proposed expected value normalized metrics have better discriminatory power and consistency, suggesting that the IR community should seriously consider expected value normalization when computing nDCG and MAP.

Summary: Illegal logging is a major cause of tropical forest loss. Satellite-based alert systems can accurately estimate tree cover loss in logging concessions using 10 m scale satellite data, but reliability is lower in areas with few disturbances. There is a trade-off between aggregation level and accuracy in estimating logging volumes, which presents a challenge for remote verification of logging activities.

Summary: Analytic functions in the Hardy class H-2 over the upper half-plane are uniquely determined by their values on any curve Γ lying in the interior or on the boundary of the upper half-plane. This paper aims to provide a sharp quantitative version of this statement, giving explicit upper bounds in certain cases and implicit upper bounds in others. The results can be extended to other domains conformally equivalent to the upper half-plane.

Summary: Quantifying uncertainty in forest assessments is challenging due to various sources of error and approaches to propagation. Model fit uncertainty is more important than uncertainty in individuals when dealing with large-scale assessments. Four different approaches to representing model uncertainty were compared and found to be in good agreement. Uncertainty in model fit did not vary with the number of trees in the inventory, while uncertainty in predicting individuals was higher with smaller numbers of trees. The importance of uncertainty sources varied with forest type, with larger importance in poor model fit situations. Both sources of allometric uncertainty should be accounted for, but when large numbers of individuals are involved, the contribution of uncertainty in predicting individuals can be ignored.

Summary: This study found that individuals in standard instrumental conditioning tasks respond slowly when the expected value is low, which is associated with an increased motivation to search for alternatives in the environment. The reward-related bias scaled with environment value, was caused by persistent searching after target was found, and was linked to increased exploration of objects in the environment. A novel computational model of foraging suggests that this search strategy could be adaptive in naturalistic settings with uncertain rewards.

Summary: Microbial communities in agricultural soils have a significant impact on plant growth and wine quality in vineyard ecosystems. This study used sequencing techniques to investigate the assembly processes of bacteria and fungi in the soil of a wine-growing region in Italy. The results showed that deterministic selection and dispersal played a dominant role in bacterial assembly, while stochastic processes were more important for fungal assembly. The influence of dispersal limitation increased at larger spatial scales, particularly for fungal communities. This study highlights the importance of considering dispersal limitation and environmental conditions when managing microbial communities in vineyard soils.

Summary: Coastal upland forests are experiencing widespread mortality due to sea-level rise and changes in precipitation and storm regimes. The loss of these forests has significant implications for the coastal carbon cycle, but predicting the likelihood of mortality is challenging. The TEMPEST experiment addresses this by studying the effects of freshwater and estuarine-water disturbance events on tree function, species composition, and ecosystem processes in a deciduous coastal forest in Maryland, USA.

Summary: This study investigates the impact mechanisms of carbon and nitrogen limitations on dissolved organic matter (DOM) metabolism in hyporheic zones (HZs). The results show that the thermodynamics of DOM and organic nitrogen are relevant at different depths in the HZ, suggesting that aerobic respiration (AR) is limited by multiple competing processes in the HZ.

Summary: Antarctica's extreme environmental conditions impose selection pressures on microbial communities, but the specific bacterial clades affected by selection processes and their ecological strategies in such conditions remain unknown. This study successfully detected bacterial clades subjected to homogeneous and heterogeneous selection and found that only the homogeneous selection clades showed high abundance and signs of microdiversity across all samples. The majority of the ASVs within each homogeneous selection clade clustered into a unique operational taxonomic unit and inhabited a specific environment. The findings suggest the existence of microdiversification leading to sub-taxa niche differentiation, with putative distinct ecotypes adapted to a specific environment. Homogeneous selection clades in the study site may have phylogenetically conserved traits that accelerate their rate of evolution and enable them to adapt to strong spatio-temporally variable selection pressures.

Summary: Lakes play a crucial role in the global carbon cycle, and understanding the interactions between microbial and dissolved organic matter (DOM) diversity is essential for predicting the function of lake ecosystems. This study used high-throughput sequencing and mass spectrometry to investigate the structure and patterns of DOM and microbial communities in six lakes. The results showed a strong correlation between molecular-level DOM diversity and the diversity of microbial communities, indicating a dynamic feedback mechanism. The study also found that deterministic assembly processes governed DOM composition, while microbial community composition was highly variable across lakes with different environmental conditions. Overall, understanding the coupling between DOM and microbial communities is important for predicting future lake ecology and function.

Summary: The microbial decomposition of organic matter in river corridors plays a crucial role in the nutrient and energy cycles of natural ecosystems. Recent advancements in omics technologies allow for the generation of large-scale molecular data that can inform biogeochemical models. However, the assumption that all detected organic compounds are bioavailable and that aerobic respiration is solely driven by thermodynamics may not be universally valid due to the complexity of organic matter degradation.

Summary: Pyrogenic organic matter (PyOM) from wildfires is resistant to biological degradation, but recent studies suggest that it may be more bioavailable than previously thought. This study used a substrate-explicit model to assess the potential bioavailability of representative PyOM compounds compared to dissolved organic matter (DOM). The results showed that PyOM has a greater range of potential bioavailability than natural DOM, but the predicted thermodynamics and metabolic rates were similar between the two. The study also found that different chemistries within PyOM have varying carbon use efficiencies, which could impact process-based model representations.

Summary: River corridors are crucial to the Earth system, and the hyporheic zone, located below the riverbed, plays a significant role in their biogeochemistry. Organic matter, fueling microbial respiration, is influenced by its chemistry and diversity. This study examined the relationship between organic matter diversity and aerobic respiration rates. The findings indicate that respiration rates are primarily controlled by organic carbon concentration, with some additional effects of organic matter richness. Other variables can suppress respiration rates below the maximum associated with the richness-to-concentration ratio.

Summary: Terrestrial disturbances are causing disruptions to the hydrologic cycle through changes in vegetation-mediated water use and microclimate. This review synthesizes the literature on post-disturbance ecohydrological coupling, examining the relationship between vegetation and streamflow under changing disturbance regimes, atmospheric CO2, and climate. Disturbance can lead to decoupling between transpiration and streamflow by altering the connectivity, size, availability, and spatial distribution of their source pools. Successional trajectories and changing climate can further impact decoupling. A framework of testable hypotheses is proposed to better understand the processes regulating ecohydrological coupling and guide future research.
