Summary: Drought poses significant risks to the stability of groundwater-dependent ecosystems in drylands. This study examines the impact of ecological drought on vegetation transition, ecological resilience, and ecosystem services in arid endorheic basins. The findings show that different plant species exhibit contrasting water use strategies driven by eco-physiological traits and environmental regimes. However, both low-resilient and high-resilient vegetation tend to undergo bistable transition under drought stress. Ecological drought accelerates catastrophic shifts in Haloxylon ecosystems, reducing ecological resilience and ecosystem services.

Summary: This study investigates the changes in vegetation spatial patterns after large-scale straw checkerboards restoration projects in the sand dune systems of the Tengger Desert in northern China. The results show that after 5 years of restoration, vegetation cover, plant species richness, and diversity increased rapidly, approaching the level of the naturally vegetated sand dunes. In addition, a larger diversity of patch sizes and a constant positive recovery rate in vegetation cover were observed, which are consistent with theoretical predictions of transitions to alternative ecosystem states.

Summary: This study reconstructed an optimized ecological polder wetland and a lake wetland using landscape design and evaluated the alternative stable states of the two wetland ecosystems using emergy/eco-exergy and fractal dimensions. The results showed that the reconstructed wetland ecosystems were dominated by renewable energy flows and were highly sustainable. The fractal dimensions of the wetlands reflected their spatial occupation capacity. The study is important for exploring the symbiosis between traditional culture and the ecological environment in wetland-rich regions with severe disturbances.

Summary: As the global population and living standards rise, the demand for basic amenities increases. The linear economy approach has led to waste production and resource depletion, giving rise to the concept of the circular economy. By reducing energy and resource consumption, the circular economy has the potential to protect the environment and improve the economy.

Summary: The concepts of ecological thresholds and alternative stable states have been proposed to explain nonlinear changes. However, a lack of data and research experience has hindered the advancement of these theories and their managerial applications. This study integrates Chinese cases and data from the China Ecological Thresholds and Alternative Stable States Database (CETASSD) to provide a comprehensive understanding of ecological thresholds and alternative stable states in different ecosystems in China. The study identifies several peculiarities of the Chinese case studies and suggests future research directions and applications of ecological thresholds.

Summary: Recent studies have shown that natural populations may get stuck in low diversity states following an adaptive radiation, due to mutations of small phenotypic effect. These low diversity states can be maintained by limited resources and finite population sizes, despite the presence of higher-diversity stable states.

Summary: The relationship between biodiversity and ecosystem functions has been widely studied, but the variation in ecosystem functions across systems with similar species diversity has been rarely addressed. In this study, a food web model and empirical data were used to examine the relationships between species richness and variation in ecosystem functions. The results suggest that the variation in ecosystem functions is influenced by trophic interactions and the diversity of basal species, which has implications for biodiversity loss and ecosystem predictability.

Summary: Critical transitions occur in various real-world systems and forecasting their occurrence is of great interest. This study introduces a powerful early warning signal called dynamical eigenvalue (DEV) that estimates the dominant eigenvalue of a system using bifurcation theory. The efficacy of the DEV approach is demonstrated in model systems with known bifurcation types and tested on various critical transitions in real-world systems.

Summary: Temperature and biodiversity changes can affect the ecological stability of natural food webs, but their joint effects are unclear. This study assessed these effects in 19 planktonic food webs and found that warmer temperatures were associated with lower stability, while biodiversity had inconsistent effects. The responses of stability were linked to the contributions from different trophic groups and the synchrony of species within the food web.

Summary: Climate change is causing a northward shift of the boreal biome, but evidence of this shift is rare. Using satellite data, researchers found that tree cover change in the North American boreal biome has a strong north-south asymmetry, with no expansion at the northern boundary but a marked increase in the core range. However, tree cover declined at the southern boundary due to wildfires and logging, indicating a possible contraction of the biome that could lead to long-term carbon declines.

Summary: Self-organized patterning resulting from biological and physical processes is widespread in nature. Previous studies have shown that biologically triggered self-organization can enhance ecosystem resilience, but the role of purely physical forms of self-organization remains unknown. In a Red Beach salt marsh in China, physically self-organized mud cracking was found to be an important facilitating process for the establishment of seepweeds. The cracks can promote plant survival and growth, enhance water infiltration, and contribute to the resilience of the salt marsh landscape.

Summary: In this study, we analyze climate and carbon cycle indicators from marine sediments to investigate three major punctuated events during the late Paleocene-early Eocene warming. The results suggest that these events were triggered by climate-driven carbon cycle tipping points, and there is an intensifying coupling between the carbon cycle and climate during the long-term warming trend.

Summary: The costs of climate change are often expressed in monetary terms, but this brings up ethical concerns. This study calculates the costs in terms of the number of people excluded from the 'human climate niche', which represents the historically consistent distribution of population density with respect to temperature. It was found that current climate policies leading to 2.7 degrees C global warming by the end of the century could leave one-third of the global population outside this niche, emphasizing the urgency for decisive action to address climate change.

Summary: Theory suggests that long, negative feedback loops may destabilize food webs as complexity increases. However, the specific ways in which these feedbacks affect ecosystems' response to environmental change have received less attention. In this study, we describe five ways in which these feedbacks might lead to abrupt transitions and species losses. By combining models, we show that the likelihood of such transitions increases with the number of interacting species and the stability of network patterns. These findings raise questions about the stability of ecosystems under global environmental change.

Summary: Species functional traits can affect pathogen transmission, host status, and infection risk. Our study on European waterbird species found that traits like diet guild and dispersal ability influence host status and pathogen diversity. We also discovered a correlation between community-level risk of HPAI H5Nx occurrence and the community-weighted means of functional traits. Additionally, we found that functional diversity can reduce infection risk. These findings emphasize the importance of integrating trait-based ecology in understanding diversity-disease relationships and provide insights for HPAI prediction and prevention.

Summary: Understanding community phylogenetic and functional structures in forest communities during succession is limited by the lack of long-term time-series data. Using a 68-year dataset, we found that community phylogenetic structure became more dispersed, while functional structure shifted from overdispersion to clustering over time. Species colonization increased phylogenetic diversity, while species with similar traits to residents were more likely to colonize, resulting in functional clustering. Our study highlights the importance of colonization and extinction in shaping community structures over long-term succession.

Summary: We investigate the cascading effects of microplastic ingestion by fish on both upper and lower trophic levels in a well-studied aquatic ecosystem model, and find that increasing microplastics in planktivorous fish can cause population structure effects and abrupt declines in fish biomass and reproduction, leading to an ecosystem-level tipping point.
