The Kuroshio Current (KC) transports and distributes this heat and moisture from the WPWP to the northern mid-latitudes. Despite the KC’s importance, its long-term evolution and links to the development of the WPWP remain unclear. Here we investigate the history of the Tsushima Warm Current (TWC), a branch of the KC, to constrain the evolution of the KC and WPWP. Diatom assemblages and diatom-based paleo-temperature index from Integrated Ocean Drilling Program Sites U1425 and U1430 in the Japan Sea reveal the history of the TWC since ∼15 Ma. The early TWC entered the Japan Sea from ∼12 to 11 Ma, coinciding with the emergence of the proto-KC and WPWP attributed to the gradual constriction of the Indonesian Gateway. Presence of tropical-subtropical diatoms in the Japan Sea from 10 to 7 Ma provides new evidence for TWC's inflow, accompanied by stronger KC. The absence of warm-water diatoms in the Japan Sea from 7 to 4 Ma indicates a cessation of TWC's inflow, accompanied by weaker KC linked to late Miocene global cooling. From 4 to 3 Ma, the repeated inflow of the TWC into the Japan Sea was associated with establishment of the modern KC and modern WPWP, in response to final closure of the Panama Seaway and further restriction of the Indonesian Gateway. From 3 to 2 Ma, the intensity of TWC became weak due to Northern Hemisphere Glaciation, corresponding to weakening of the Kuroshio system and WPWP. Following the Mid-Pleistocene Climate Transition, WPWP contracted and TWC periodically flowed into Japan Sea as a result of sea-level related controls on the strength of KC and the relative restriction of Tsushima Strait.</div></div>","PeriodicalId":11481,"journal":{"name":"Earth and Planetary Science Letters","volume":"661 ","pages":"Article 119385"},"PeriodicalIF":4.8,"publicationDate":"2025-04-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143877491","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"地球科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Zooarchaeology by mass spectrometry (ZooMS) indicates macropods (the family of forest wallabies) persisted until at least 4400–4200 years ago, with skeletons being reused for bone point manufacture. The capture, translocation, exchange, hunting, and recycling of marsupials was part of a wider process of ‘culturing’ island biomes centred around New Guinea in the Terminal Pleistocene to Mid Holocene.

Multiobjective Optimization Approaches (MOAs) have emerged as potential solutions within this domain. The major components explored in this review include the objective functions, decision variables, and optimization techniques within MOAs. Despite their potential, few studies comprehensively address the key concepts of these components, the role of stakeholder involvement, the limitations of existing research, and the emerging technological opportunities that could enhance MOAs in the FEWN. The Preferred Reporting Items for Systematic Reviews and Meta-Analyses protocol, was combined with Meta-ethnography to select, review, and analyze the literature. The data synthesis was done by meta-ethnography, finding key terms to categorize objective functions, decision variables, and optimization techniques and developing key concepts related to MOAs in the FEWN. Key terms for categorizing objective functions are maximizing economic, environmental, and social benefits and food, energy, and water security. For the decision variables, the key terms include availability, accessibility, and sufficiency, while the optimization techniques are Mathematical Programming and Metaheuristics. Besides, emerging technologies create substantial opportunities to improve the performance of MOAs.

We report 10 spatio-temporal swarms of earthquakes that occurred along ∼175 km of the northern and central Taupō Volcanic Zone (TVZ) March–September 2019. The swarms lack clear mainshock-aftershock distributions, suggesting involvement of pressurized fluids. The most energetic swarms occurred beneath the southwestern flank of Whakaari/White Island volcano (WI) and were accompanied by elevated SO<sub>2</sub> emissions and ∼8 mm southwest displacement of the edifice. Focal mechanisms of the WI swarms suggest horizontal dilation in the direction of tectonic extension achieved by slip along networks of closely spaced, NE-striking normal faults linked by oblique-slip to strike-slip faults. Given the small GNSS displacements and upward-migrating swarms, we favor the interpretation that magmatic volatiles were released along faults in response to changes in crustal stress. Based on the punctuated, cascading nature of swarms along the northern TVZ, we hypothesize that faults and magmatic systems are fluid-rich, experiencing aseismic creep, and critically stressed, raising the possibility that small changes in crustal stress from slow slip along the Hikurangi subduction zone caused a reduction in the minimum horizontal stress. This change occurred along the entire northern TVZ over ∼5 months, potentially contributing to widespread volcanic unrest. The probable release of magmatic fluids from shallow magma bodies in the vicinity of WI between May and June argues against a causal relation to the 9 December 2019 WI eruption.</p>","PeriodicalId":50422,"journal":{"name":"Geochemistry Geophysics Geosystems","volume":"26 4","pages":""},"PeriodicalIF":2.9,"publicationDate":"2025-04-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1029/2024GC012079","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143875658","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"地球科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Furthermore, heterotrophic responses to changes in C : N : P ratios are probably modulated by autotrophic responses to light and C : N : P ratios, which modify the amount and composition of photosynthetic exudates and increase competition for nutrients. Effects on functional properties like the use of organic compounds by the heterotrophic biofilm community are largely unknown. We conducted a stream mesocosm experiment with a factorial design with different C : N : P ratios and light availability levels to test direct and indirect effects on heterotrophic biofilm functioning via community‐level physiological profiles in benthic and hyporheic biofilms. When inducing a resource C : N : P ratio closer to heterotrophic microbial biomass C : N : P ratios, we found an increased functional diversity of metabolized substrates, especially in hyporheic biofilms. Furthermore, this alteration shaped substrate preferences toward less P‐containing substrates and more N‐containing substrates in early‐stage biofilms. Despite the absence of a direct impact of light on hyporheic biofilms, we detected a propagation of a benthic autotrophic effect into hyporheic biofilms. Light availability induced effects on hyporheic bacterial density and the use of phenolic compounds, amino acids, and carbohydrates. In benthic biofilms, only the use of carbohydrates was affected by light. These results emphasize the significant indirect effects of benthic autotrophs on the functionality of hyporheic microbial heterotrophs and suggest consequences of human impacts, such as nutrient inputs and clear‐cutting, on stream nutrient cycling.","PeriodicalId":18143,"journal":{"name":"Limnology and Oceanography","volume":"44 1","pages":""},"PeriodicalIF":4.5,"publicationDate":"2025-04-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143876143","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"地球科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, several possible mechanisms can also give rise to FTE-like features in the boundary layer and potentially mislead observational analysis; the KHI is one such candidate. Using two-dimensional magnetohydrodynamics (MHD) simulations, we examine and categorize the signatures observed by several virtual satellites as they pass through the Kelvin–Helmholtz waves along different trajectories. We have shown that the bipolar signatures were identified during the satellite's passage across the spine region and the leading/trailing edge of the KH vortex. The duration of bipolar signatures was also shown to vary depending not only on where the satellite trajectory intersects with the vortices, but also on the density asymmetry on both sides of boundary which in turn affects the relative motion between the vortices and satellite. Further, slight adjustments to the projection angle of the magnetic field are also applied in the simulations, as the signatures of the KHI are very sensitive to the in-plane magnetic field component. These results can be used as diagnostics when analyzing spacecraft data to help distinguish KHI-created signatures from FTE.</p>","PeriodicalId":15894,"journal":{"name":"Journal of Geophysical Research: Space Physics","volume":"130 4","pages":""},"PeriodicalIF":2.6,"publicationDate":"2025-04-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143877816","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"地球科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Our findings reveal that over the past two decades, built-up land expansion had significantly degraded habitat quality, and rural settlement expansion had a substantially greater negative impact on habitat quality compared to urban growth, particularly in areas with high rural population densities. The difference in impact is mainly attributed to the lack of unified planning in rural development, while urban follows strict, intensive, and green planning, with increasing emphasis on mitigating human activities’ impact on the eco-environment. Further projections indicate that the expansion rate of built-up land in China would slow down over the next 30 years, leading to a reduced impact on habitat quality.
