Ecological impacts of climate change on Arctic marine megafauna

David Gremillet et al.

Summary: Global warming has a greater impact on the Arctic than any other region. Media continuously highlight the threat of climate change to Arctic wildlife, particularly iconic megafauna like polar bears, whales, and seabirds. However, our understanding of the ecological impacts on marine megafauna in the Arctic is limited, with significant gaps in research in the Russian Arctic and a focus on exploited species like cod. This article presents a synthesis of recent scientific advances and outlines ten key questions for future research, advocating for a methodology that combines long-term Arctic monitoring, involvement of local communities, and the use of high-tech and big data approaches.

A global meta-analysis on the responses of C and N concentrations to warming in terrestrial ecosystems

Yuan Sun et al.

Summary: Global warming increases carbon concentrations in plant leaves, stems, and microbial biomass, as well as nitrogen concentrations in stems, while decreasing soil carbon concentrations and carbon-to-nitrogen ratios. These effects are more pronounced with longer duration and greater magnitude of warming.

Summary: The response of soil organic carbon (SOC) to warming in terrestrial ecosystems is influenced by crop-produced carbon inputs and soil warming, with different residue return ratios affecting SOC variations in a plastic film mulching system. Careful comparison should be made on SOC changes under plastic film mulching with different residue management practices.

Temperature optimum for marsh resilience and carbon accumulation revealed in a whole-ecosystem warming experiment

Alexander J. Smith et al.

Summary: Coastal marshes are important carbon dense ecosystems that are both maintained and threatened by sea-level rise. This study found that moderate temperature increases can maximize root growth, marsh elevation gain, and belowground carbon accumulation. However, higher temperatures were associated with marsh elevation loss and increased carbon mineralization, suggesting potential risks of marsh drowning.

Effects of Warming and Phosphorus Enrichment on the C:N:P Stoichiometry of Potamogeton crispus Organs

Mingzhe Dai et al.

Summary: The loss of submerged macrophytes in freshwater ecosystems is increasing due to the combined effects of eutrophication and climate change. Different functional plant organs of submerged macrophytes show distinct responses to phosphorus (P) addition and warming, indicating the importance of evaluating the responses of different organs to environmental changes. Interactive effects between P addition and warming were observed, emphasizing the importance of considering multiple factors. Overall, P addition can help submerged macrophytes resist the adverse effects of high temperatures and different propagules have varying sensitivity to P enrichment.

Aridity modifies the responses of plant stoichiometry to global warming and nitrogen deposition in semi-arid steppes

Chuang Yan et al.

Summary: Global warming and nitrogen deposition can unbalance the stoichiometry of carbon, nitrogen, and phosphorus in terrestrial plants. Water availability can regulate these effects. Experimental results from desert, typical, and meadow steppes show that warming can increase nitrogen use efficiency and competitiveness of forb plants in desert steppes, but reduce carbon:nitrogen and carbon:phosphorus ratios in typical and meadow steppes. Nitrogen addition decreases the carbon:nitrogen ratios in all three steppes and increases nitrogen:phosphorus ratios. The effects of warming and nitrogen addition have synergistic effects on carbon:nitrogen and carbon:phosphorus ratios in all three steppes, which enhance the productivity of grass plants. Water availability also modulates the effects of stoichiometry, and its influence is related to aridity and nitrogen deposition.

Climate warming masks the negative effect of microplastics on plant-soil health in a silt loam soil

Gull Nayab et al.

Summary: Anthropogenic pressures, such as microplastics pollution and climate change, have unpredictable consequences on soil ecosystem functioning. This study found that polyhydroxyalkanoate (PHA) stimulated microbial biomass and enzyme activity, altering soil quality and ecosystem multifunctionality, but also promoted N immobilization and plant-microbe nutrient competition, reducing plant health. PVC and PE had limited effects on soil quality and plant health. Furthermore, heat stress had a more noticeable impact than microplastics.

Extreme drought exacerbates plant nitrogen-phosphorus imbalance in nitrogen enriched grassland

Xiao-Sa Liang et al.

Summary: The nitrogen-phosphorus (N-P) imbalance induced by N enrichment is a growing concern in ecology. This study investigated the interactive effects of N addition and extreme drought on N:P ratios in a grassland ecosystem. The results showed that extreme drought could exacerbate the N-induced N-P imbalance and have significant impacts on species turnover and community-level N:P ratios. These findings highlight the complexity in predicting ecosystem N-P imbalance under the influence of multiple global change drivers.

Future warming-induced phosphorus loss mitigated by land conversion and degradation

Lianhua Liu et al.

Summary: In the context of global climate change, understanding future soil organic carbon (SOC) dynamics and diffuse phosphorus pollution is crucial for sustainable soil and water management in agricultural watersheds. Using simulation models, the study found that climate-induced land-use changes were the main driver of SOC changes and diffuse phosphorus pollution. Furthermore, expanding paddy fields could help mitigate diffuse phosphorus pollution in the future.

Responses of soil enzyme activity and soil organic carbon stability over time after cropland abandonment in different vegetation zones of the Loess Plateau of China

Hongwei Xu et al.

Summary: The study showed that after cropland abandonment, there are significant differences in soil enzyme activity, SOC stability, and driving factors in different vegetation zones. In steppe and forest-steppe zones, soil enzyme activity increased while SOC stability decreased with recovery time; whereas in the forest zone, both parameters remained relatively stable. The changes in soil enzyme activity and SOC stability were closely related to vegetation diversity, coverage, and soil nutrient levels in different recovery sites.

Microbial metabolic response to winter warming stabilizes soil carbon

Jing Tian et al.

Summary: The study reveals that winter warming on the Tibetan Plateau results in reduced microbial decomposition and enhanced physical protection of organic compounds in soil, leading to the enhanced physical preservation of SOC. This divergent response of SOC persistence to winter warming compared to year-round warming highlights the important role of soil microorganisms in aggregate life cycles and suggests potential negative feedbacks to global climate change.

Soil fungal mycelia have unexpectedly flexible stoichiometric C:N and C:P ratios

Tessa Camenzind et al.

Summary: The study revealed unexpected high flexibility in C:N and C:P values of saprobic fungi along nutrient supply gradients, questioning microbial homeostasis. Fungal N:P varied less due to simultaneous reductions in mycelial N and P contents. Internal recycling processes and reduced N and P uptake during mycelial growth may be more relevant than element storage.
