Abstract Global interest and investment in nature‐based solutions (NbS) are rapidly increasing because of the potential this approach to concurrently counter biodiversity loss, provide cost‐effective measures for climate change adaptations, maintain natural processes that underpin human health wellbeing. Recognition is growing grasslands many regions will protect carbon stores more effectively than forests warmer, drier, fire‐prone conditions future while also serving as hotspots biodiversity. Yet have received less attention their NbS potential. Despite wide‐ranging goals approach, investments focused narrowly on using plants meet pledges, often without considering plant interactions with herbivores abiotic environment jointly control ecosystem functioning success solutions. Here, we review roles large small vertebrate invertebrate play ability world's solutions, a focus wild herbivore impacts storage. Synthesis . Planning holistic, ecologically informed view includes role interaction allow likely achieve successful, sustainable outcomes.

Grassland is one of the largest terrestrial biomes, providing critical ecosystem services such as food production, biodiversity conservation, and climate change mitigation. Global land-use intensification have been causing grassland degradation desertification worldwide. As primary medium for energy flow biogeochemical cycling, carbon (C) cycling most fundamental process maintaining services. In this review, we first summarize recent advances in our understanding mechanisms underpinning spatial temporal patterns C cycle, discuss importance grasslands regulating inter- intra-annual variations global fluxes, explore previously unappreciated complexity abiotic processes controlling balance, including soil inorganic accumulation, photochemical thermal degradation, wind erosion. We also how changes could alter balance by modifying water budget, nutrient additional plant processes. Further, examine why increasing aridity improper land use may induce significant losses stocks. Finally, identify several priorities future research, improving strengthening monitoring dynamics integrating ground inventory, flux monitoring, modern remote sensing techniques, selecting appropriate species combinations with suitable traits strong resistance to fluctuations, which would help design sustainable restoration strategies a changing climate.

Abstract Artificial Intelligence (AI)-driven language models (chatbots) progressively accelerate the collection and translation of environmental evidence that could be used to inform planetary conservation plans strategies. Yet, consequences chatbot-generated content have never been globally assessed. Drawing on distributive, recognition, procedural, epistemic dimensions justice, we interviewed analysed 30,000 responses from ChatGPT ecological restoration expertise, stakeholder engagements, techniques. Our results show more than two-thirds chatbot’s answers rely expertise male academics working at universities in United States, while largely ignoring low- lower-middle-income countries (7%) Indigenous community experiences (2%). A focus planting reforestation techniques (69%) underpins optimistic outcomes (60%), neglecting holistic technical approaches consider non-forest ecosystems (25%) non-tree species (8%). This analysis highlights how biases AI-driven knowledge production can reinforce Western science, overlooking diverse sources perspectives regarding research practices. In fast-paced domain generative AI, safeguard mechanisms are needed ensure these expanding chatbot developments incorporate just principles addressing pace scale worldwide crisis.

Abstract. Particulate organic carbon (POC) and mineral-associated (MAOC), which are two primary components of the soil (C) reservoir, have different physical chemical properties as well biochemical turnover rates. Microbial necromass entombment is a mechanism for MAOC formation from fast-decaying plant substrates, whereas POC typically considered product structural litter via fragmentation. However, emerging evidence shows that microbial by-products derived labile C substrates can enter pool. To date, it still unclear to what extent dissolved pool how affects subsequent long-term (SOC) storage. Our study here, through 13C-labeling experiment in 10 soils 5 grassland sites modeling analysis, showed up 12.29 % isotope-labeled glucose (i.e., C) was detected In addition, glucose-derived correlated with 13C-MBC (microbial biomass carbon) fraction clay silt, suggesting flow dependent on interactions between processes. The analysis ignoring MBC significantly underestimated sequestration by 53.52 across soils. results emphasize mineral-regulated process, besides residues, significant contributor POC, acting vital component SOC dynamics.

In times of unprecedented climate change, ecological restoration efforts have a strong focus on forests for the purpose carbon sequestration. Grasslands, in contrast, remain relatively neglected global policies. Concurrently, we are midst biodiversity crisis—it is estimated that 1 million species globally threatened with extinction. Here, present analyses from central Europe and southern Brazil show majority our endangered plant fact found open ecosystems. Using Germany as an example, could reduce extinction risk by up to 82% if restore open, grassy This also holds true Brazil, where grassland constitute single largest share species, but ecosystems continue be systematically We further expand argument include role can play mitigating change. posit ramping may not only best bet bend curve loss, it will make critical contribution resilience dynamic decades come.

Poales are one of the most species-rich, ecologically and economically important orders plants often characterise open habitats, enabled by unique suites traits. We test six hypotheses regarding evolution assembly in closed habitats throughout world, examine whether diversification patterns demonstrate parallel evolution. sampled 42% species obtained taxonomic biogeographic data from World Checklist Vascular Plants database, which was combined with open/closed habitat scored experts. A dated supertree constructed. integrated spatial phylogenetics regionalisation analyses, historical biogeography ancestral state estimations. Diversification result dynamic evolutionary processes that vary across lineages, time space, prominently tropical southern latitudes. Our results reveal recurrent trait transitions species-rich families Poaceae Cyperaceae. Smaller display divergent trajectories. The have achieved global dominance via notable, spatially phylogenetically restricted divergences into strictly habitats.
