This “filtering” of water minimizes point source discharges through canals, but mangroves may also play an important role in the cycling of plastic pollution that reaches the Bay. The objectives of this study are to determine: 1) The composition of debris in the Bay’s mangroves and 2) How the structure of mangrove forests affects debris distribution. Debris was hypothesized to be more abundant further into the forest due to trapping by vegetation, and mesoplastics (5 mm – 2.5 cm) would be positively correlated to macroplastics (&gt; 2.5 cm) due to fragmentation. Nine transects were surveyed and debris was recorded by size and potential origin. 94.5% of all debris was plastic of which 57.8% were fragments. Negative binomial generalized linear regression was used to relate total plastic and mesoplastic densities to distance from shoreline, elevation, basal area, prop root and pneumatophore cover, and mangrove seedling abundance. Plastic increased with distance from shore and basal area, although the latter was just above the <em>p</em>-value cut-off of 0.05 for mesoplastic (<em>p</em>-value = 0.0513), and was weakly negatively related to prop root coverage. Total plastic was weakly negatively related to red mangrove seedlings and pneumatophore coverage, although these relationships were less clear. Mesoplastic and macroplastic were positively correlated (<em>p</em>-value &lt; 0.05). Selected mangrove forests of Biscayne Bay appear to be sinks for plastic debris, where it accumulates in the interior forest from which it is unlikely to escape.</p>","PeriodicalId":23640,"journal":{"name":"Wetlands","volume":"77 1","pages":""},"PeriodicalIF":2.0,"publicationDate":"2024-02-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139977257","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"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}

The objective of this work is to develop an operational geomatic approach for the delineation, evaluation and use of information on North African wetlands. The Digital Atlas made it possible to highlight another aspect of this significant diversity of wetlands in western Algeria, through a new technique for presenting the results used in a web mapping. In the context of global changes driving a steep erosion of biodiversity, this study shows the importance of wetlands in western Algeria and allows citizens to learn about the richness, beauty and extent of their natural heritage. It contributes to public awareness and provides a valuable assessment and evaluation tool available to decision makers and professionals in the field of nature management and conservation. The findings of this study demonstrate, among other things, that considerable scientific advances of a practical kind may be made in the field of remote sensing.

Constructed wetlands are considered as an effective method to purify water bodies. However, the removal rate of nitrogen (N), phosphorus (P) and other nutrients by wetland vegetation is quite different, and the continuous observation of plants and water ecosystems is required. In this study, the growth curves of two subtropical wetland plants, <i>Phragmites australis</i> and <i>Zizania caduciflora</i>, and their absorption effects on N and P in constructed wetlands were studied. The results showed that the growth curves of the two wetland plants were similar, reaching the biomass peak in July to August, and the cumulative absorption of N and P by plants had the same trend with the change of biomass. The N and P concentration of plants reached the peak in March to April, with higher concentration in <i>Phragmites australis</i> than that of <i>Zizania caduciflora</i>. At the end of the growing season, i.e. around October 20, the accumulated absorption of N and P by plants reached the maximum, which was the optimal time for harvest of subtropical wetland plants. Thereafter, the residues of plant litter entered the water, causing the recovery of N and P concentration in the water body, therefore affected the purification function of wetland. There is a strong correlation between the water purification efficiency and plant growth. With the increase of biomass, N and P accumulation in <i>Phragmites australis</i> and <i>Zizania caduciflora</i>, the N, P content and chemical oxygen demand (COD) in the water of wetland showed a significant decreasing trend. The removal rates of N, P, COD and suspended substance (SS) in the constructed wetlands with <i>Phragmites australis</i> and <i>Zizania caduciflora</i> as the main plants were 95%, 96%, 82% and 86%, respectively. In general, the purification capacity of <i>Phragmites australis</i> is slightly higher than that of <i>Zizania caduciflora</i> and precipitation had positive effects on the pollutants concentration of wetland water.

Intensive agriculture may have adverse impacts on oxbow functions, especially if wetlands receive water inputs from subsurface drainage systems (e.g., tile drainage). To explore the influence of tile drainage on oxbow wetland communities, we quantified relationships between physical and biotic variables in 12 Iowa, USA oxbows over a two-year period (June to August 2019–2020). Six oxbows received direct water inputs from tile drainage (multipurpose oxbows), whereas remaining sites did not (non-tiled oxbows). In each oxbow, we measured physical variables and documented taxonomic composition, diversity, and abundance of macrophytes, macroinvertebrates, and fishes. Although water temperature was lower in multipurpose oxbows, values for other physical variables (e.g., turbidity, conductivity, and total dissolved solids) were similar across sites. No significant difference was detected for any biotic variable between oxbow types. In total, we observed 44 invertebrate taxa in both oxbow types with an average richness of 18.6 in non-tiled oxbows and 17.5 in tile-fed oxbows. We sampled 35 fish species, with an average richness across sampling dates of 8.2 in non-tiled oxbows and 11.4 in multipurpose oxbows. A total of 2682 Topeka shiners were found in both non-tiled and multipurpose oxbows. Non-metric multidimensional scaling revealed that potential physical determinants of macrophyte, invertebrate, and fish abundance were unrelated to tile drainage.

The plant species composition of these wetlands was quantified and 33 ecological design methods were accessed across the values of water quality protection, shoreline maintenance, ecological facilities, and plant diversity. Employing structural equation modeling, design methods significantly influencing plant diversity were identified. Key findings reveal: (1) variances in plant species and design methods occurred across wetlands, with the Xixi Wetland in the urban core displaying higher biodiversity; (2) four design methods—ecological conservation measures, rain gardens, complex plant community structure, and increased hydrophytic species populations—significantly impacted wetland plant diversity; (3) divergent pathways of design methods can be used to improve plant diversity in different urban wetlands; and (4) rational ecological design enhances plant diversity but may have time-limited effects, necessitating ongoing management to be effective.

Annual net primary production (ANPP) of <i>Morella cerifera</i> and key environmental drivers were measured long-term (1990 – 2007) across a chronosequence of shrub age on a mid-Atlantic barrier island. Soil and groundwater nutrients were compared with un-encroached grassland soil to evaluate impacts of vegetation on nutrient dynamics. Shrub ANPP declined with age at the same rate among all thickets, but there was variability from year to year. When climate variables were included in models, shrub age, precipitation, and freshwater table depth were consistent predictors of ANPP. Water table depth decreased over time, reducing ANPP. This may be due to rising sea-level, as well as to feedbacks with shrub age and evapotranspiration. Soil N and C increased with shrub age and were higher than adjacent grassland sites; however, there was a significant loss of N and C to groundwater. Our results demonstrate that drivers influencing the encroachment of shrubs in this coastal system (i.e., warming temperature) are not as important in predicting shrub primary production.

However, there is currently no research on the ecological networks in the Hebei-Tianjin coastal wetlands. In this study, the morphological spatial pattern analysis method is employed to identify wetlands sources, while the minimum cumulative resistance model is used to extract potential ecological corridors.
