Salt accumulation resulting from wetland drying and sea level rise is a critical factor governing carbon dynamics in CVE soils. However, our understanding of the relationship between SOM decomposition and the PE under increasing salt stress remains limited in CVEs. In this study, we conducted a microcosm experiment with a full factorial design with salt stress and straw input to investigate the intensity of the PE and its contribution to SOM decomposition. Our findings revealed that salt stress reduced the rate of SOM decomposition, significantly impacting the intensity of the PE throughout the incubation period. Straw input induced a strong positive PE in the early stage under low salt stress, whereas high salt stress led to a markedly negative PE in the later stage of incubation. Salt stress and exogenous straw input collectively resulted in a notable decrease in soil prokaryotic diversity with salt-tolerant and oligotrophic microbial species playing pivotal roles in highly saline and SOM-deficient soils, accompanied by a relatively high fungi to bacteria ratio. The microbial co-occurrence network demonstrated a relatively high degree of modularity under nutrient-poor conditions, suggesting a cometabolic driving force for SOM decomposition. This study elucidates the response of SOM decomposition induced by exogenous straw input under salt stress and highlights the influence of microbial metabolic strategies on the SOM turnover in CVEs.</p>","PeriodicalId":16003,"journal":{"name":"Journal of Geophysical Research: Biogeosciences","volume":"130 6","pages":""},"PeriodicalIF":3.7,"publicationDate":"2025-06-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144213828","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Kim,&nbsp;Russell Kelley","doi":"10.1002/ecy.70095","DOIUrl":"https://doi.org/10.1002/ecy.70095","url":null,"abstract":"&lt;p&gt;Coral reefs in Timor-Leste are a hotspot of marine biodiversity within the Coral Triangle, a region encompassing six member states in Southeast Asia and the Pacific, housing the highest levels of marine biodiversity globally. Timor-Leste lies between Indonesia and Australia in the Indonesian Throughflow, a significant oceanographic feature connecting the Pacific and Indian Oceans. The Throughflow plays an essential role in regulating global climate, and we claim that it provides food to coral reefs in Timor-Leste and creates conditions favorable for corals in the context of ocean warming. The Ombai and Timor Straits, sitting to the north and south of Timor-Leste, are important outflows of the Throughflow with a respective 3-year mean transport of 4.9 and 7.5 Sv (1 Sv = 10&lt;sup&gt;6&lt;/sup&gt; m&lt;sup&gt;3&lt;/sup&gt; s&lt;sup&gt;−1&lt;/sup&gt;) from 2004 to 2006 (Gordon et al., &lt;span&gt;2010&lt;/span&gt;).&lt;/p&gt;&lt;p&gt;Coral reef surveyors (The University of Queensland) identified a bloom of pyrosomes along the north coast of Timor-Leste in September–October of 2019 (Figure 1a, Video S1). The water was filled with spiky, white and red pyrosomes, &lt;i&gt;Pyrosoma atlanticum&lt;/i&gt; (Péron, 1804) (Tunicata, Thaliacea), an open water (pelagic) and planktonic, free-living colonial tunicate as far as the eye could see. Pyrosome blooms were identified at two different sites, Ataúro Island and Be'hau, about 2 weeks apart. At both sites, high current conditions swept the pyrosomes up onto shallow (&lt;10 m) coral reefs. At Be'hau, pyrosomes were spotted “stuck” onto two individual corals of two different species: &lt;i&gt;Hydnophora&lt;/i&gt; cf. &lt;i&gt;pilosa&lt;/i&gt; and &lt;i&gt;Duncanopsammia peltata&lt;/i&gt; (Arrigoni et al., &lt;span&gt;2014&lt;/span&gt;; Kelley, &lt;span&gt;2022&lt;/span&gt;). There was considerable extension of mesenterial filaments of &lt;i&gt;H. pilosa&lt;/i&gt; (Figure 1b) which are used to digest food inside or outside of the coral mouth within a polyp. At both sites, pyrosomes were numerous, drifting from the deep blue depths to the surface (Figure 1a, Video S1).&lt;/p&gt;&lt;p&gt;The pyrosomes were likely swept up to shallower depths through intrusive upwelling of the Indonesian Throughflow current that raised the local oceanic thermocline above the depth of the shelf break without breaking the sea surface (Furnas, &lt;span&gt;2011&lt;/span&gt;). Because intrusive upwelling does not reach the sea surface, it is undetectable via satellites, resulting in an underestimation of the importance to thermal energy flow and marine biology. Pyrosomes are typically found in global oceans from 50° N to 50° S, primarily in deeper ocean environments &gt;75 m depths (Figure 2; Appendix S1; Kim, &lt;span&gt;2025&lt;/span&gt;). They follow a typical planktonic daily migration pattern, ascending during the night to feed and migrating a vertical distance of nearly 1 km each day. During the day, pyrosomes are found at &gt;75 m depths (Andersen &amp; Sardou, &lt;span&gt;1994&lt;/span&gt;), and observations in Timor-Leste were during the day on shallow reefs, contrary to the established daily migration.

High-frequency and reliable carbon accounting is the foundation for enabling government agencies to reduce emissions efficiently and reach carbon peaks. However, traditional carbon accounting methods are hindered by their poor timeliness, low accuracy, and coarse granularity. To overcome these challenges, this study proposed a high-frequency, high-precision, and traceable city-level carbon accounting framework. This framework enhanced the accuracy and real-time performance of carbon accounting while incorporating a dynamic early warning system for urban carbon emissions, strengthening government emergency response capabilities, and ensuring informed decision-making for low-carbon urban development. The effectiveness of the model was demonstrated through a case study using data from four municipalities in China. Our principal findings were as follows: (1) The proposed framework integrated multi-source, cross-domain big data, significantly improving carbon accounting frequency and precision, enhancing early warning accuracy and timeliness, and ensuring data traceability. (2) The proposed ResTCN surpassed traditional methods, achieving a mean absolute percentage error (MAPE) of less than 4.5 %. (3) The dynamic carbon emission early warning method achieved a MAPE of less than 2 % in carbon emission forecasting. These results demonstrated that the framework not only enhanced data traceability but also improved the accuracy and timeliness of carbon accounting and early warnings, providing a robust foundation for cities to develop targeted carbon reduction policies and accelerate the transition to low-carbon cities.</div></div>","PeriodicalId":349,"journal":{"name":"Journal of Cleaner Production","volume":"517 ","pages":"Article 145873"},"PeriodicalIF":9.7,"publicationDate":"2025-06-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144213205","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Establishing thresholds for behavioural plasticity can improve management and minimise human-carnivore conflicts. We analysed GPS data from 116 tagged jaguars (<em>Panthera onca</em>) across their range to investigate their spatiotemporal and behavioural responses to different levels of human disturbance. Specifically, we evaluated spatial (movement) and temporal (diurnality) responses and foraging, resting, and other behavioural response in females and males. We also examined resource selection among jaguars exposed to low, moderate, and high levels of disturbance. Our findings reveal that human activity decreases the distance jaguars travel and reduces diurnality in females and males, with these effects being stronger in highly disturbed areas. Human presence significantly reduces the time spent foraging and resting in both sexes, while other behaviours remain less affected. Jaguars consistently select highly productive and habitat-diverse areas, avoiding human-accessible regions, regardless of the disturbance level. Interestingly, jaguars in highly disturbed areas avoid regions with high livestock density, favouring human-populated areas instead. Conversely, jaguars in low and moderately disturbed areas prefer livestock-rich regions while strongly avoiding human settlements. These results highlight jaguars' behavioural plasticity and adaptive strategies as they navigate human-modified landscapes. Understanding these complex behavioural adjustments provides valuable insights for future conservation efforts, including more effective strategies to manage jaguar populations while mitigating conflicts with humans across their distribution range.

Addressing these issues through appropriate interventions is therefore of vital importance. To make meaningful predictions about the ways in which future interventions and exogenous factors could influence the behaviour of bushmeat trade actors, we conducted scenario-based interviews with bushmeat vendors in urban markets in two of the main bushmeat trading cities in Central Africa – Yaoundé in Cameroon and Kinshasa in the Democratic Republic of the Congo. We found that three of the five scenarios – successful demand-reduction campaign, improved enforcement, and providing livelihood or enterprise training – could encourage market vendors to stop selling protected species or leave the trade altogether. Reasons given for the willingness to change included the increased risk of being arrested or a significant drop in the level of profit. On the other hand, our exogenous scenario – the increased cost of domestic meat – could make bushmeat more competitively priced and encourage more consumption. We recommend tightening control of bushmeat supply to urban markets, reducing urban demand and providing appropriate training to encourage market vendors to leave the trade. We also recommend supporting local producers of alternative proteins to increase the supply of viable alternatives at a competitive price.</div></div>","PeriodicalId":55375,"journal":{"name":"Biological Conservation","volume":"309 ","pages":"Article 111276"},"PeriodicalIF":4.9,"publicationDate":"2025-06-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144212342","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
