Concentrations of dissolved sulphate, dissolved iron, total dibenzothiophenes and specific conductance were significantly higher in wetlands near to surface mining operations. In addition, beta diversity of wetland invertebrates was higher in wetlands further afield of the industrial centre. Drivers of benthic assemblage differences among sites include specific conductance and pH.

Three <i>Phragmites</i> haplotypes (Delta-, EU- and Gulf-types) co-occur in marshes of the Mississippi River Delta (MRD), where a recent dieback of <i>Phragmites</i> has prompted investigations about the potential for recolonization by seed. In other areas of the US, the invasive EU-type has been shown to spread by seed, yet little is known about reproduction modes of the Delta- and Gulf-types. We conducted a survey at 35 sites along the Mississippi River Delta region in southeast Louisiana to examine the potential for sexual reproduction across haplotypes as well as the potential for hybridization. Seed and pollen samples were collected from <i>Phragmites</i> populations to examine flowering phenology and determine pollen viability of the three lineages. We also conducted a seedbank assay in stands of three haplotypes to test the potential for recruitment by seed. Despite the observed potential for sexual reproduction in Delta- and EU- types, no <i>Phragmites</i> seedlings germinated from the seedbank. EU was the only haplotype to exhibit germination from seeds collected from seed heads. Both spatial separation and temporal isolation in flowering times indicate that hybridization between <i>Phragmite</i>s haplotypes in the lower MRD is unlikely. High pollen production, increased pollen production following dieback, and viable seeds in the EU-type suggest that this invasive haplotype has a greater potential to invade new areas and adapt to stressors through sexual reproduction compared to than Delta-or Gulf haplotypes.</p>","PeriodicalId":49363,"journal":{"name":"Wetlands Ecology and Management","volume":null,"pages":null},"PeriodicalIF":1.8,"publicationDate":"2024-07-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141744244","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}

Now birds, as indicator of this biodiversity, have to breed, winter or stopover in wetlands embedded in a complex and highly altered human matrix. They may concentrate their activities in the wet remnant (wet reedbed) or suboptimal habitats (dry reedbed) and surroundings such as agricultural fields (maize). In a wide wetland area situated south-west of France in a main migration route, we tested if the abundance of passerine species differs among habitats according to their specialization and ecology (wet reedbed vs dry habitats; aquatics vs generalists; migrant vs local), We attempt to identify the underlying mechanisms of observed variation, looking at: arthropod availability in each habitat, bird diet of five insectivorous species and refuelling capacity of birds. Maize crops hosted more invertebrates and biomass than reedbeds for Coleoptera, Diptera, Araneida and Cicadellidae. This may explain why crops were used by aquatic passerines (Bluethroat, Sedge warblers, Reed warblers), migrant or local generalists (Robin, Blue tit, Great tit, Willow Warblers and Nightingale). Bluethroat’s diet was more focused on Formicidae and used the both habitats. In spite of the available food in maize, specialist birds preferred reedbed: Cetti warbler feeding in mainly Araneida and Cicadellidae; Sedge warbler Aphid and Coleoptera. Dry reedbed were better used by Grasshopper Warblers foraging Formicidae. Sedge and Reed warblers were more abundant in wet reedbed. We also noted for this last species youngs refuelling in maize crop. Therefore, the strategy to use maize crop may be different if resident or migrant. Generalist resident may disperse searching for food or transit area in continuity of vegetation; migrant need refuelling, particularly the aquatic trans-saharans more specialist on reedbed than the others. Finally, maize crop provided food resources and suitable shelter for a large group of species. It may be a supplement habitat of the wet and dry reedbeds, but not a substitute. Our study reaffirms to conserve and extend wet reedbed habitats threatened by clogging bush encroachment and drying.</p>","PeriodicalId":49363,"journal":{"name":"Wetlands Ecology and Management","volume":null,"pages":null},"PeriodicalIF":1.8,"publicationDate":"2024-07-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141552260","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}

NWI and C-CAP were compared in five study sites spread across the Atlantic and Gulf coasts and align well under a four-class system, but discrepancies arise under a nine-class system, with C-CAP generally estimating smaller net wetland areas, larger emergent vegetation areas, and smaller scrub vegetation areas. The average overall accuracy for the C-CAP and NWI comparison is 89.4% and 82.4% for the coarser and finer scale classification systems, respectively. DECODE is available for two of the representative sites and uses a three-class system that differs from that of C-CAP and NWI, causing significant errors and an average overall accuracy of 59.5%. LULC change was quantified during the 1996 to 2016 period using the multi-temporal C-CAP and DECODE maps, showing that DECODE estimates significantly more change, by a factor of fifteen at one study site.. A spatial analysis of the classification differences shows that they often occur near the boundary of two wetland classes and within agricultural and built-up areas.

In a mesocosm study, we raised pH to levels seen in Wycamp Lake (over 8.5), where <i>Z. palustris</i> restoration success was limited, and found decreased germination by 50% and seedling biomass by 60%.

Our experiment examined the leaf litter breakdown of two species, <i>Eucalyptus grandis</i> (exotic) and <i>Inga uruguensis</i> (native), in the soil of riparian zones at subtropical highland grasslands. During the spring season, fine and coarse mesh litterbags with exotic and native leaf litter were incubated in riparian zones with (n = 3) and without (n = 3) tree and shrub layers, resulting in a total of 72 litter bags. In each sampling site, the dry weight of the natural litter was measured, and soil samples were collected for basic physical–chemical analysis. After 42 days of incubation, the remaining material in litter bags was weighed. Our study provided partial support for our hypothesis that the presence of trees and shrubs in riparian vegetation and edaphic macrofauna would enhance litter breakdown, particularly for high-quality litter. Surprisingly, the chemical and physical properties of the soil and riparian vegetation presence did not have a significant impact on the decomposition process, indicating efficient nutrient cycling in soil systems. However, the presence of edaphic fauna, especially soil macroinvertebrates, played a critical role in facilitating leaf litter breakdown. Additionally, we observed rapid breakdown rates for high-quality litter, aligning with our expectations, despite its exotic origin.

The fluctuations in the quantity of these sources influence bacterial metabolic activity which is, in turn, directly linked to the trophic food web. Our study, reports the inter-annual variability of nutrients and dissolved organic carbon in addition to their impact on phytoplankton and bacterial biomass, respiration and production in the Mandovi and Zuari estuaries of southwest India. Radio-labeled substrates, NaH¹⁴CO₃, and titrated thymidine (³H-TdR) were employed to quantify primary productivity (PP) and bacterial productivity (BP), respectively. Our findings revealed that community respiration exceeded PP indicating a state of heterotrophy. Similarly, bacterial respiration (BR) exceeded BP suggesting that carbon is predominantly utilized for respiratory rather than assimilatory action. Analysis of BP/PP (Mandovi 0.48 to 4.46; Zuari 1.72 to 3.81) and PP/BR (Mandovi 0.02 to 1.42; Zuari 0.05 to 1.00) ratios showed considerable seasonal variability. Lower bacterial growth efficiency observed in Mandovi (average 30.35%) than Zuari (average 38.38%) suggests greater productivity in Zuari. Uncoupling of phytoplankton and bacteria during the monsoon and post-monsoon seasons implied heterotrophic conditions in both Mandovi and Zuari.
