Radionuclide transport from soil to plants is important for radiological contamination of food and estimation of internal radiation doses from consuming contaminated food. Wheat, clover, purslane and soil samples were collected from agricultural fields in the semi-arid region of Iğdır, Türkiye. The concentrations of 137Cs, 40K, and stable Cs were measured and soil-to-plant transfer factors were calculated. The concentrations of 137Cs (derived from global fallout deposition), 40K and stable Cs in soils ranged from 1.9 to 8.4 Bq kg−1, 318–2033 Bq kg−1 and 1.6–18.5 mg kg−1 respectively. The geometric mean concentrations of 137Cs, 40K and stable Cs in wheat grain were measured as 8.4 Bq kg−1 dry wt., 417 Bq kg−1 dry wt. and 3.6 mg kg−1 dry wt. respectively. Geometric mean value of the soil to stem of cereal (wheat), grass (clover) and leafy vegetable (purslane) transfer factor (Fν) for 137Cs were estimated as 5.7 x 10−2, 2.8 x 10−2 and 9.2 x 10−2 which were higher than values reported in IAEA-TRS 472 except grain of wheat which was approximately equal to that of temperate climate values 1.1 x 10−1. The Fν values of stable Cs were estimated somewhat lower than that of Fν of 137Cs for wheat grain, wheat stems, clover and purslane.

Wildfire severity is increasing in the western United States. Simultaneously, many recognize that fire is a natural process and advocate for learning to live with fire. Indeed, the naturalness of fire can be an important reason provided to increase the amount of fire on a landscape. However, “naturalness” can be interpreted in incommensurate ways, such as the historic range of variability of a system or the absence of human influence. What makes wildfires feel natural or unnatural to the people who experience them, and how naturalness affects reactions to wildfires is underexplored. Using social representations theory, we examine the 2023 Lookout Fire at the H. J. Andrews Experimental Forest (HJA). We use semi-structured interviews (n = 40) to explore how the research community associated with the HJA mentally constructs and uses naturalness to emotionally process and make meaning from the wildfire. We find even in a community with advanced training in ecology, respondents use a variety of metrics to determine naturalness, including ignition source, fire behavior, and pre-fire landscape characteristics and fire history. Respondents consider a variety of factors, and there was not consensus on whether the Lookout Fire was a “natural” fire. In general, respondents who described the fire as more natural were able to come to a state of acceptance and excitement for future research opportunities sooner than respondents who described the fire as largely unnatural. This has important implications for wildfire risk communication for scientists and practitioners who want to restore fire as a natural process. While fires perceived (or framed) as natural may be more readily accepted, fires perceived as unnatural may take longer to process. Fires perceived as human-caused and especially as climate-exacerbated may be the most difficult for people to process after and during the fire, and may have the most resistance for being managed for purposes other than full suppression.

Hydrate-based CO2 storage (HBCS) has emerged as a promising approach within carbon capture and storage (CCS) technologies, offering a potential pathway for mitigating CO2 emissions. The permeability of hydrate-bearing sediments (HBSs) is crucial for predicting the feasibility of HBCS, yet the seepage mechanisms become quite complex during the formation or dissociation of hydrates. The objective of this paper is to investigate the hydrate pore habits and the evolution of key physical properties at both macroscopic and microscopic scales, utilizing an integrated set of methodologies such as CT scan, nuclear magnetic resonance and ultrasonic pulse methods, and present a theoretical equation that correlates P-wave velocity with permeability for HBSs. The results indicate that the theoretical equation effectively explains the correlation between P-wave velocity and permeability. Formations with a lower initial water saturation and a higher proportion of type Ⅱ pores (ranging from 0.1 to 200 μm) were found to promote high-efficiency CO2 storage. During CO2 hydrate formation, the pore structure becomes progressively more complex, and hydrates are initially formed in the pore center at saturations around 0–10 %. The occurrence pattern transitions from a pore-filling pattern to a grain-coating pattern as hydrate saturation increases. The theoretical equation relating P-wave velocity to permeability is useful for assessing the permeability of HBSs. These findings provide valuable insights into HBCS in porous media and contribute to the selection of potential CO2 storage sites.

Ecological compensation is increasingly used to offset habitat and biodiversity loss resulting from changes in land use, large infrastructure projects (e.g., roads and railroads) or industrial expansions (e.g., mines, harbours), but the effectiveness of specific compensation strategies remain largely untested. When old-growth forest ecosystems are impacted by such projects, designated compensation areas may also require additional restoration or habitat enrichment. For organisms that rely on habitats that require decades to develop, such as advanced decayed wood, restoration will require novel approaches. We tested whether translocation of deadwood of various decay stages and large dimensions enhance saproxylic beetle communities within compensation areas in a large boreal forest landscape in Sweden. Experimental plots (50 m in diameter) within the compensation zone were enriched with 0, 16, or 48 deadwood substrates. We collected beetles using flight intercept traps prior to translocation and again 1 and 4 years after translocation and compared species richness, abundance and assemblage composition across treatment and over time. We showed that translocation of relatively high densities of deadwood (48 substrates per plot) increased species richness of saproxylic beetles. Increased beetle richness could have occurred from direct transport of beetles in experimental substrates and/or through attraction of beetles to the translocated substrates. Our results indicate that translocation of deadwood can serve as an important tool in ecological compensation and restoration if sufficient amounts of deadwood are translocated. While promising, the long-term success of restoring saproxylic biodiversity through translocation of deadwood depends on whether translocated substrates continue to provide suitable habitat for beetles over time and whether benefits for biodiversity can be enhanced through targeted translocation of specific combinations of deadwood.

<p>The 30th Conference of the Parties (COP30) of the United Nations Framework Convention on Climate Change (UNFCCC), to be held in Belém, provides a unique opportunity for Brazil to affirm its commitment to protecting Amazon forests and to showcase leadership in aligning ambitious climate action with global conservation goals. Encouraging progress has been made in controlling deforestation in the Amazon (Figure 1a–d). The 2024 preliminary Brazilian Amazon official deforestation increment estimate was 5816 km<sup>2</sup>, 27.5% below 2023 and a staggering 54.2% below 2022 (INPE <span>2025</span>). This is the lowest annual deforestation increment in a decade and 26.4% below the average of the 2008–2024 period (INPE <span>2025</span>). Such achievement is closely tied to the restoration of command and control in the Amazon, highlighted by the reinstatement of the Action Plan for the Prevention and Control of Deforestation in the Legal Amazon (PPCDAm) (MMA <span>2023</span>). Nevertheless, deforestation is not the only threat facing Amazon's forests.</p><p>Beyond deforestation, forest degradation represents a significant yet often overlooked threat to tropical forests. While deforestation is a binary process referring to the complete removal of tree cover, leading to a permanent land-use change, forest degradation is the reduction of a forest's capacity to supply ecosystem services, leading to a loss of ecological value, where tree cover remains but undergoes structural and functional changes, ultimately impairing resilience and long-term sustainability (Berenguer et al. <span>2024</span>; Lapola et al. <span>2023</span>). Nearly 40% of the Amazon's standing forests are degraded by drivers including fire, edge effect, timber extraction, and extreme drought events, further emphasizing the scale and importance of the issue (Lapola et al. <span>2023</span>). The 2023–2024 strong Amazon drought, with rainfall deficits of 50–100 mm/month, a +3°C temperature rise, a two-month delay in the wet season, and record-low river levels (Marengo et al. <span>2024</span>), appears to have compounded a recent rise in forest degradation. Brazil's official forest degradation alerts in the Brazilian Amazon in 2024—including wildfire scars, selective logging, and other forms of forest degradation that are unrelated to drought—reached 25,023 km<sup>2</sup>, an increase of 44% compared to 2023 (17,473 km<sup>2</sup>) and 163% compared to 2022 (9549 km<sup>2</sup>) (INPE <span>2025</span>) (Figure 1d). In 2024 and 2023, wildfire scars accounted for about 66% of total degradation alerts, compared to just 38% in 2022 (INPE <span>2025</span>).

Under the global trend of carbon peak and neutrality, the effectiveness of the carbon emission in construction industry remains unverified. This research investigates the impact of carbon emission policies on green innovation in the construction industry. Utilizing a multi-period Difference-in-Differences (DID) model, this study analyzes data on the quantity and quality of green innovation patents. Findings indicate that carbon peaking policies significantly enhance both the quality and quantity of green innovations, particularly in fossil fuel decarbonization and pollution control. The analysis reveals that the policy's short-term effects are stable and do not exhibit lagging impacts. This study provides a framework for assessing the influence of carbon emission policies on green innovation, aiding in the formulation of effective carbon emission strategies tailored to the industrial context.

Spatial synchrony, the tendency for temporal fluctuations in an ecological variable to be positively associated in different locations, is a widespread and important phenomenon in ecology. Understanding of the nature and mechanisms of synchrony, and how synchrony is changing, has developed rapidly over the past 2 decades. Many recent developments have taken place through the study of long-term data sets. Here, we review and synthesise some important recent advances in spatial synchrony, with a focus on how long-term data have facilitated new understanding. Longer time series do not just facilitate better testing of existing ideas or more precise statistical results; more importantly, they also frequently make possible the expansion of conceptual paradigms. We discuss several such advances in our understanding of synchrony, how long-term data led to these advances, and how future studies can continue to improve the state of knowledge.

Blue carbon ecosystems (BCEs) represent a significant natural solution for climate change mitigation through their capacity to sequester large amounts of organic carbon. These coastal habitats also provide an array of co-benefits, such as biodiversity enrichment, livelihood support, and opportunities for tourism and recreational activities. However, these ecosystems are increasingly threatened by human activities, including unsustainable tourism practices. To get a deeper understanding into the current trends and uncover key research gaps related to tourism synergies and trade-offs with BCEs, we conducted a global systematic literature review of published research The review highlights the evolution of tourism impacts on BCEs. Our findings reveal a significant increase in publications related to tourism impacts and BCEs from 2016, peaking in 2021. Ecology-based studies dominate the research space, with nearly half of the studies concentrating solely on ecotourism, underscoring its prominence within tourism research. Mangroves emerge as the most frequently reported ecosystem type, with most studies conducted in Indonesia and China. When tourism synergies and trade-offs were mapped, it showed that ecotourism is strongly associated with synergies including raising conservation awareness and promoting pro-environmental behaviours. Economically, ecotourism contributes to income generation and livelihood development. However, ecotourism activities have also reported trade-offs linked to ecosystem damage, loss, and environmental pollution. These findings emphasize the dual role of tourism as both a potential driver of ecosystem conservation and a contributor to environmental degradation. Our findings emphasize the need for sustainable tourism initiatives that align with conservation goals and socioeconomic and cultural interests. Holistic and integrated approaches to ecosystem and tourism management are also needed to achieve more sustainable outcomes.

These coastal habitats also provide an array of co-benefits, such as biodiversity enrichment, livelihood support, and opportunities for tourism and recreational activities. However, these ecosystems are increasingly threatened by human activities, including unsustainable tourism practices. To get a deeper understanding into the current trends and uncover key research gaps related to tourism synergies and trade-offs with BCEs, we conducted a global systematic literature review of published research The review highlights the evolution of tourism impacts on BCEs. Our findings reveal a significant increase in publications related to tourism impacts and BCEs from 2016, peaking in 2021. Ecology-based studies dominate the research space, with nearly half of the studies concentrating solely on ecotourism, underscoring its prominence within tourism research. Mangroves emerge as the most frequently reported ecosystem type, with most studies conducted in Indonesia and China. When tourism synergies and trade-offs were mapped, it showed that ecotourism is strongly associated with synergies including raising conservation awareness and promoting pro-environmental behaviours.

Although the Matang Mangrove Forest Reserve (MMFR) in Malaysia is suggested to be a global reference for sustainable silviculture, the impact of greenwood extraction on local biodiversity and ecological functionality remains under-researched. To fill this gap, a rapid biodiversity assessment was conducted using birds as ecological indicators to investigate the effect of mangrove silvicultural management on avian communities. Changes in the diversity of bird species and dietary guilds in response to forest age and management were assessed using the point-count method with visual and auditory observations. This was done in both “productive” forests, consisting of even-aged Rhizophora plantations producing poles and charcoal, and in “protective” forests where extractive activities are prohibited. Remarkably, all avifaunal functional guilds were present in both young “productive” and “protective” forests, however the “productive” forests supported fewer bird assemblages in terms of species richness and total taxonomic diversity compared to the floristically rich and structurally complex “protective” forests. The bird species’ response to silvicultural disturbances also varied, with adverse effects especially occurring in functionally specialized species. Furthermore, back mangroves and transition zones to terrestrial forests were found to support a higher avifaunal diversity, possibly because of the enhanced habitat heterogeneity. Finally, this study highlights the use of bird communities as ecological indicators for assessing the quality of mangrove forests, and emphasises the crucial role of habitat and landscape heterogeneity in supporting diverse avifauna and ecosystem functionality highlighting the need for more research integrating mangroves and adjacent ecosystems.

Decades of deforestation and unsustainable land use have created extensive areas of degraded and deforested land across the central Congo Basin, contributing substantially to climate change and biodiversity loss. Recently, nature-based solutions have gained increasing interest, particularly those focusing on forest restoration for long-term carbon sequestration and additional societal benefits for human well-being. Thus, forest restoration, especially with native species, offers a viable pathway to address environmental and social challenges while supporting local communities. However, both technical and scientific knowledge about many native species' performance in large-scale plantations, which could serve the current and future needs of central African countries, is currently lacking. To address these knowledge gaps, we established an experimental plantation in Yangambi, Democratic Republic of the Congo, to evaluate the potential of native tree species in comparison with the fast-growing exotic species Acacia auriculiformis, which is often planted in monoculture at a large-scale in the central Congo Basin. From 37 promising native species initially selected, the seeds of 19 were successfully harvested from the natural forest. Among these, 16 species yielded sufficient seedlings in the nursery and were planted in the field. After five years, five native species (Pachyelasma tessmannii, Piptadeniastrum africanum, Irvingia smithii, Ongokea gore, and Canarium schweinfurthii) demonstrated growth, survival, and carbon sequestration performance comparable to Acacia auriculiformis. This illustrates that local tree species are promising alternatives for exotic species. Nevertheless, further research is necessary to optimize the large-scale production of native seedlings, including improving seed conservation and nursery techniques. Drawing on the ongoing forest restoration initiatives in Yangambi, we emphasize the importance of integrating local knowledge and actively involving local communities to ensure the successful implementation and long-term sustainability of tree-planting efforts, benefiting both nature and human well-being.
