Through this study, we defined lowland white-cedar forest community types in unharvested and harvested forest stands within the State of Michigan and examined community type associations with ecological variables. Data collected in unharvested stands revealed three white-cedar community subtypes: (1) cedar-deciduous, (2) cedar-conifer, and (3) cedar-shrub. These unharvested subtypes were dominated by white-cedar, yet characterized by different soils, hydrology, geochemical gradients, and associated tree species. In harvested stands, six community types were identified: (1) aspen-fir, (2) winterberry-willow, (3) balsam fir, (4) cedar-red maple, (5) cedar-black spruce, and (6) alder-tamarack. These harvested community types were located along ecological gradients, including soil type (organic or mineral) and soil water pH. Using community types in unharvested and harvested stands, and associated ecological gradients, potential pathways of compositional transition were theorized. Findings suggest that cedar community subtype affects the likelihood of cedar regeneration and dictates the alternative species replacing cedar after harvest. These findings and potential pathways are useful to forestry practitioners, as they highlight potential changes in tree species dominance following harvest across a range of lowland white-cedar community types, allowing refinement of silvicultural prescriptions to ensure desired outcomes.","PeriodicalId":49363,"journal":{"name":"Wetlands Ecology and Management","volume":"42 1","pages":""},"PeriodicalIF":1.8,"publicationDate":"2024-02-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140002734","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}

Therefore, it is of great importance to ensure the wise use of wetlands. Local residents’ attitudes toward sustainable tourism in wetlands are essential to the sustainable management and wise use of this resource. This study examined the attitudes of local communities towards sustainable wetland tourism in three wetland areas in Northern Serbia. The survey was implemented to 1078 households randomly selected from seven communes (20 settlements) adjacent to chosen Ramsar sites. Using SPSS 25, the data was subsequently processed, assessed, and explained. In addition to descriptive statistics, a correlation was used to determine the factors that affect locals’ attitudes toward the development of sustainable wetland tourism. The study shows that local residents generally hold positive attitudes towards sustainable wetland tourism. Age, length of residency, gender, employment, education and income are observed to be significantly impacting attitudes toward sustainable wetland tourism. Although there is a high level of awareness of the risks to wetlands, there is doubt regarding their understanding of the state of wetlands’ protection and the particular issues they face. On the other hand, there is no doubt that locals are ready to protect wetlands for upcoming generations. For sustainable wetland tourism, management, and conservation, it is crucial to connect management organizations, tourism representatives, and people. In this matter, it is important to improve communication and connection between the mentioned stakeholders.","PeriodicalId":49363,"journal":{"name":"Wetlands Ecology and Management","volume":"60 1","pages":""},"PeriodicalIF":1.8,"publicationDate":"2024-02-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139956844","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}

These patterned fens harbor rare and uncommon species and serve as habitats for endangered wildlife (e.g., woodland caribou, whooping cranes). In this study, utilizing Google Earth Pro (1) we documented 1083 ribbed fens and 250 reticulate fens in the province of Alberta, Canada; (2) determined the regional variation in patterned fen occurrences; (3) described the various morphological forms of patterned fens; and (4) recognized these as six distinctive peatland site-types. Patterned fens are not randomly arranged on the landscape. Ribbed fens are concentrated on regional high elevational uplands and montane benchlands with morainal deposits, while reticulate fens are more numerous on low elevation plains with glacial-fluvial and glacial-lacustrine deposits. Patterned fens vary along minerotrophic vegetation and chemical gradients and have a complex set of morphological types. To our knowledge, this is the first study that provides base line information on the abundance and distribution of patterned fens in Alberta and associates morphological patterned fen types with environmental or geological characteristics.

In this study, we used an integrated approach to estimate the radiocarbon (14C) chronology, sedimentation rate, and nutrient dynamics of the Khushalsar wetland in the Kashmir Himalaya. A UWITEC gravity corer was used to retrieve a 60 cm sediment core from the wetland. Accelerator mass spectrometer (AMS) facilitated 14C dating of core sediments revealed that the age of the sediments ranged from 248 ± 30 BP at 15–16 cm depth to 889 ± 27 BP at 59–60 cm depth. The linear increase in 14C age with depth revealed steady depositional conditions. According to the Constant Rate of Supply model applied to 14C ages, the sedimentation rate for Khushalsar wetland averaged 0.10 cm per year over the past 829 years, spanning from 1189 to 2018. Physicochemical analysis revealed a high concentration of ionic components in the sediments, wherein the electrical conductivity (EC) ranged from 2230 to 2970 µS cm−1, and organic matter (OM) ranged from 6.6 to 19.8%. The regression model demonstrated significant (p < 0.05) positive and negative associations between the physicochemical parameters. EC explained 91% of the variation in total dissolved solids (TDS) and 89% of the variation in salinity, whereas organic carbon (OC) explained 44% of the variation in nitrogen and 20% of the variation in phosphorus. Depth exhibited a strong positive association with C/N ratio (explaining 17% of the variation) and a negative association with OC, nitrogen, and phosphorus (explaining 59%, 56%, and 50% of the variation, respectively). The study concluded that primary productivity, stormwater runoff, anthropogenic inputs (domestic sewage, raw fecal matter, slaughterhouse wastes), and deforestation in the catchment area are responsible for the increased nutrient concentration and high sedimentation rate in the wetland.","PeriodicalId":49363,"journal":{"name":"Wetlands Ecology and Management","volume":"1 1","pages":""},"PeriodicalIF":1.8,"publicationDate":"2024-02-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139765326","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}

Mature cypress can survive indefinitely in permanently flooded sites, but experience mortality at salinities as low as 2 to 3 ppt. Thus, ghost trees in permanently inundated sites can indicate mortality due to increased salinity. Ghost cypress were mapped along the margins of the Neuse River estuary and fluvial-estuarine transition zone (FETZ), along with co-indicators of salinity as a potential cause of death. The distribution was compared with other indicators of upstream propagation of SLR effects; all occurred within a 25 km river reach. Many ghost cypress are consistent with SLR-driven mortality, but in the upper FETZ the co-indicators argue against it, and throughout the study area some ghost cypress lack co-indicators of salinity effects and may have been killed by other factors. The upstream limit of ghost cypress with co-indicators suggesting possible SLR-driven mortality, and the downstream limit of Nyssa aquatica and N. biflora, whose habitats and niches overlap almost entirely with Taxodium except for less salinity tolerance, occur downstream of other indicators of the leading edge of SLR. The furthest upstream is the hydraulic impact of backwater effects on river flow. Downstream, other effects are encountered: a transition from occasionally to frequently flooded wetlands, sedimentary burial of Pleistocene alluvial terraces, and a shift from dominantly mineral floodplain soils to Histosols. The ecological indicators of cypress and tupelo are furthest downstream. Hydraulic (backwater) effects are the leading edge of SLR impacts on the Neuse, trailed by geomorphological, sedimentological, and pedological indicators. Though biota often respond more rapidly to changes than landforms and soils, ecological indicators such as ghost cypress and forest-to-marsh transitions that are salinity dependent are the downstream-most sentinels of sea-level encroachment in rivers.","PeriodicalId":49363,"journal":{"name":"Wetlands Ecology and Management","volume":"69 1","pages":""},"PeriodicalIF":1.8,"publicationDate":"2024-02-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139765017","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}

In this paper, we assess the effect of management on the reed bed Coleoptera community by investigating reed beds subject to winter cutting, winter harvest, short-term unmanaged (3 years), and long-term unmanaged (25 years). Using pit fall traps, we collected Coleoptera across a summer season to estimate Coleoptera biomass, abundance, size, richness, diversity, and community composition across the four types of management of reed beds. Cutting and harvest both show to increase Coleoptera biomass compared to unmanaged reed beds, with the highest Coleoptera abundance found in the harvested reed bed. The species richness and diversity, on the other hand, peaked in the long-term unmanaged reed bed. Community composition differed between the different management types, and across time. Species of conservation concern were most abundant in recently managed areas. These results have implications for the conservation of the reed bed Coleoptera community. First, to maintain a high Coleoptera diversity, some areas must be left unmanaged. Secondly, to secure habitats for species of conservation concern as well as boost the Coleoptera biomass, frequent management of other areas is advised. This mosaic management pattern will also create the overall most species rich reed bed, as unique Coleoptera communities were found in each management type.","PeriodicalId":49363,"journal":{"name":"Wetlands Ecology and Management","volume":"41 1","pages":""},"PeriodicalIF":1.8,"publicationDate":"2024-02-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139667908","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}

Africa is experiencing a burgeoning human population, and though border areas receive short-term pulses in transient population growth, borders often create legal and logistical barriers to long-term settlement. This lack of long-term settlement may leave border ecosystems more intact than those in more interior areas. Reptiles and amphibians are considered indicator species and thus can be used to assess the health and resilience of their habitats. We sampled the herpetofauna of three transborder wetland systems in Uganda using time-constrained visual encounter surveys during diurnal and nocturnal activity hours. We then compared the communities of these wetlands using alpha and beta diversity indices and provide baseline population data on these communities. These data will allow for future investigations of the ability of transborder wetlands to act as long-term refugia for herpetofauna, even as human populations continue to increase.

Therefore, the present study compares the macrobenthic fauna among red mangrove (Rhizophora mangle), saltmarsh (Spartina alterniflora) and adjacent unvegetated sediment (mangrove borders and saltmarsh borders) in the Furo Grande tidal channel in the Caeté estuary, northern Brazil. Overall, vegetated habitats have finer sediments, lower salinities and temperatures and higher organic matter and water content than unvegetated habitats. However, the macrofauna structure among the habitats did not fully correspond to this division, perhaps responding instead to differences among the four habitats in detrital production, tidal inundation frequency, leaf litter processing by crabs and rates of predation. Deposit feeding tubificid oligochaetes and capitellid polychaetes were particularly abundant in the mangrove and at mangrove borders probably due to greater availability of suitably processed detritus.","PeriodicalId":49363,"journal":{"name":"Wetlands Ecology and Management","volume":"225 1","pages":""},"PeriodicalIF":1.8,"publicationDate":"2024-01-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139561250","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 wetland is on sandstone on the African Erosion Surface. The depression wetland has a rim of high-lying ground surrounding a central depression. Fluctuations between wet and dry periods create both highly reducing conditions in soils during wet phases in the depression, and highly oxidising conditions in the depression margin. Under reducing conditions, iron(III) oxides that are insoluble, are reduced to soluble iron(II), which is transported to and trapped in the margins of the depression under oxidising conditions when the water table declines and iron(II) is oxidised to iron(III). There is also a moderate flux of silica from the surface in the centre of the depression to the margins, which is suggested to be associated with maximum alkalinity associated with iron(III) reduction, and decreased alkalinity in the margins associated with iron(II) oxidation. However, the main flux of silica is from the surface in the centre of the depression to depth of greater than 1.5 m, again associated with variations in pH linked to iron-cycling. These reactions have thus caused a net volume loss in the centre of the depression, causing sagging, and a net volume gain at the margins of the depression, causing swelling. Wetland formation associated with alteration of landform morphology as a consequence of alternating redox conditions represents a novel mechanism that has not yet been described.","PeriodicalId":49363,"journal":{"name":"Wetlands Ecology and Management","volume":"123 1","pages":""},"PeriodicalIF":1.8,"publicationDate":"2024-01-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139461804","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}

We analyze the potential occurrence of wetlands in the core area of the temperate Pampas region of South America, recognized for the quality of its pastures and the suitability of its soils for grain production. We mapped the spatial distribution of wetlands in the Province of Buenos Aires based on the analysis and classification of the local soil database at a scale of 1:50,000. Thus, 399 soil series were classified as hydric/non-hydric according to the scope of methods and criteria reviewed. Then we used this information to classify 2211 map units into five categories based on the percentage of hydric and non-hydric soil series: 1—hydric (100% hydric series); 2—predominantly hydric (66–99% hydric series); 3—partially hydric (33–65% hydric series); 4—predominantly non-hydric (1–32% hydric series); and 5—non-hydric (0% hydric series). We estimated wetlands cover about 35% of the province. Wetlands distribution is not uniform, we identified three main landscapes: terrestrial matrix with wetlands, mosaic of wetlands and non-wetlands, and mosaic dominated by wetland patches. Our results provide tools for land management in terms of strategies for a wise use of wetlands and their conservation. Our map shows high values of consistency with the occurrence of wetlands visually identified in high-resolution imagery (Google Earth platform). In such a highly agriculturized landscape, our results indicate a much larger wetland area compared to estimates made with optical remote sensing data classifications.
