“…Our analyses do not consider any positive effects of invasive alien species, which are generally not captured in the InvaCost database. Examples could include, for instance, an increase in biological production in semi-arid ecosystems, the restoration of industrial or contaminated areas where native species cannot survive, with benefits from the acceleration of succession and soil formation or reductions in nutrient leakage and water basin eutrophication [ 84 , 85 ], or fast-growing plants that increase carbon sequestration while outcompeting native species [ 86 ]. Alternatively, some invasive alien species such as Buddleja davidii might provide certain local economic benefits [ 87 , 88 ], although these cannot discount or undermine the presence of costs because they often affect different actors and ecosystem functions [ 89 ], and nor have they been documented or known to be anywhere close to the magnitude of costs.…”

Unveiling the hidden economic toll of biological invasions in the European Union

et al. 2023

Background Biological invasions threaten the functioning of ecosystems, biodiversity, and human well-being by degrading ecosystem services and eliciting massive economic costs. The European Union has historically been a hub for cultural development and global trade, and thus, has extensive opportunities for the introduction and spread of alien species. While reported costs of biological invasions to some member states have been recently assessed, ongoing knowledge gaps in taxonomic and spatio-temporal data suggest that these costs were considerably underestimated. Results We used the latest available cost data in InvaCost (v4.1)—the most comprehensive database on the costs of biological invasions—to assess the magnitude of this underestimation within the European Union via projections of current and future invasion costs. We used macroeconomic scaling and temporal modelling approaches to project available cost information over gaps in taxa, space, and time, thereby producing a more complete estimate for the European Union economy. We identified that only 259 out of 13,331 (~ 1%) known invasive alien species have reported costs in the European Union. Using a conservative subset of highly reliable, observed, country-level cost entries from 49 species (totalling US$4.7 billion; 2017 value), combined with the establishment data of alien species within European Union member states, we projected unreported cost data for all member states. Conclusions Our corrected estimate of observed costs was potentially 501% higher (US$28.0 billion) than currently recorded. Using future projections of current estimates, we also identified a substantial increase in costs and costly species (US$148.2 billion) by 2040. We urge that cost reporting be improved to clarify the economic impacts of greatest concern, concomitant with coordinated international action to prevent and mitigate the impacts of invasive alien species in the European Union and globally.

“…[4] coastal wetlands are biodiverse and possess one of the most productive ecosystems per unit area, storing large supplies of "blue carbon" [5]. CW-SOC is extremely sensitive to changes in factors such as temperature [6], vegetation cover [7], soil texture [8], soil moisture content [6], soil nutrients [9], land use [10], and human activities [11]. A number of sensitive factors have combined to cause serious ecological degradation of coastal wetlands and changes in SOC storage in coastal wetlands, which in turn affect the global carbon cycle [12].…”

Coastal wetland soil organic carbon (CW-SOC) is crucial for both “blue carbon” and carbon sequestration. It is of great significance to understand the content of soil organic carbon (SOC) in soil resource management. A total of 133 soil samples were evaluated using an indoor spectral curve and were categorized into silty soil and sandy soil. The prediction model of CW-SOC was established using optimized support vector machine regression (OSVR) and optimized random forest regression (ORFR). The Leave-One-Out Cross-Validation (LOO-CV) method was used to verify the model, and the performance of the two prediction models, as well as the models’ stability and uncertainty, was examined. The results show that (1) The SOC content of different coastal wetlands is significantly different, and the SOC content of silty soils is about 1.8 times that of sandy soils. Moreover, the characteristic wavelengths associated with SOC in silty soils are mainly concentrated in the spectral range of 500–1000 nm and 1900–2400 nm, while the spectral range of sandy soils is concentrated in the spectral range of 600–1400 nm and 1700–2400 nm. (2) The organic carbon prediction model of silty soil based on the OSVR method under the first-order differential of reflectance (R′) is the best, with the Adjusted-R2 value as high as 0.78, the RPD value is much greater than 2.0 and 5.07, and the RMSE value as low as 0.07. (3) The performance of the OSVR model is about 15~30% higher than that of the support vector machine regression (SVR) model, and the performance of the ORFR model is about 3~5% higher than that of the random forest regression (RFR) model. OSVR and ORFR are better methods of accurately predicting the CW-SOC content and provide data support for the carbon cycle, soil conservation, plant growth, and environmental protection of coastal wetlands.

“…Although mangroves have been exploited for centuries, our understanding of these wetland forests has greatly improved in recent decades, with a growing number of publications focusing on the ecology, management, and conservation of mangroves 14 . The biodiversity of mangroves is of increasing interest due to the threat they face from global climate change, particularly sea level rise 15 . The flora of mangroves consists of 65-69 species of vascular plants adapted to the dynamic coastal environment, while the fauna includes fish and crustacean resources 16 .…”

“…The largest contiguous mangrove system in the world is the Sundarbans in the Ganga-Brahmaputra-Meghna Delta, shared by India and Bangladesh, which covers an area of one million hectares 14,18 . Sundarbans mangrove forest is the most diverse among all mangrove forests and has many species, but some of them are facing the threat of extinction due to factors such as global warming, sea level rise, and increased salinity in the estuaries 15 . It also mentions that the constant stress faced by mangroves generates high levels of reactive oxygen radicals (ROS), which can cause damage to the plants, but the plants have a defense mechanism to scavenge off these ROS 18,19 .…”

A very tiny non-coding RNA molecule with a length of 20 to 24 nucleotides, called microRNAs or miRNAs. They control gene expression by targeting mRNAs with sequence-specificity. Depending on the degree of complementarity with the target mRNA sequences, this might result in translational repression or mRNA destruction. They are very crucial for controlling growth and development in plants. Researchers also agreed with the point that miRNAs are responsive to stress in plants. Growing in tropical and subtropical estuaries, mangrove is a very significant ecosystem both environmentally and commercially. But several natural processes, like sea level rise, salinity rise, and global warming, are disastrous for this flora, and some species are disappearing at a startling rate. Studying the function of these miRNAs in controlling mangrove homeostasis in that situation would be of utmost significance. In the most recent research, we discovered three miRNAs: ph-miR10630, ph-miR11471, and ph-miR10341 in Phoenix sp, that react to abiotic stress. This finding unmistakably indicates that miRNAs play a regulatory function in preserving cellular homeostasis. When compared to plants that are close to extinction, the experimental validation and molecular characterization of these miRNAs might provide important insights into their role in battling biotic and abiotic stress. This information would then be extremely helpful for planning the proper conservation of those plant species.INTRODUCTION: MicroRNAs (miRNAs) are a group of tiny, non-coding RNAs that play important regulatory roles in plants as well as in animals. They have persisted throughout evolution and are endogenous in nature 1 . miRNAs were first discovered in 1993 by Victor Ambros and colleagues, who noticed that the lin-4 gene, known to regulate the development efficiency of C. elegans, produced two small RNA molecules instead of a protein.
