Key questions about biophysical, chemical, and anthropogenic/societal factors influencing nutrient cycling via litterfall production and decomposition in mangrove forests were addressed. The SLR included 332 peer-reviewed original and review articles from the ScienceDirect, PubMed, and Google Scholar databases. The United States of America had the highest relative count (RC, 31.32%), followed by Japan (8.79%) and Indonesia (8.24%), and the lowest RCs were found in Bangladesh, Kenya, Philippines, and Thailand. We showed the increasing trend on these topics and discussed the milestones to enhance our understanding of litterfall production and decomposition processes and inform future research endeavors in the context of climate change. A positive trajectory for understanding litterfall production and decomposition for effective decision-making and management strategies towards mangrove conservation and sustainable use is also discussed. Ten-year research prospects were also identified, including studies on impacts of pollution, habitat degradation, climate change, and other destructive human activities. The trend in studies about mangrove litterfall production and decomposition suggests the growing recognition of mangroves’ ecological and societal importance. Future advancements can be made to better understand the biophysical, chemical, and anthropogenic factors influencing litterfall production and decomposition through the identified future research directions. Finally, the findings of the present review are relevant to supporting effective conservation and management strategies for mangroves in a changing climate.</p>","PeriodicalId":23640,"journal":{"name":"Wetlands","volume":"120 1","pages":""},"PeriodicalIF":2.0,"publicationDate":"2024-01-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139578531","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}

{"title":"Macrophytes for Utilization in Constructed Wetland as Efficient Species for Phytoremediation of Emerging Contaminants from Wastewater","authors":"Priyanka Singh, Gurudatta Singh, Anubhuti Singh, Virendra Kumar Mishra, Reetika Shukla","doi":"10.1007/s13157-024-01770-2","DOIUrl":"https://doi.org/10.1007/s13157-024-01770-2","url":null,"abstract":"<p>Emerging contaminants (EC) are the modern age chemicals that are new to the environment. It includes pharmaceuticals &amp; personal care products (PPCPs), pesticides, hormones, artificial sweeteners, industrial chemicals, microplastics, newly discovered microbes and many other manmade chemicals. These chemicals are harmful and having negative impacts on human being and other life forms. Existing treatment systems are ineffective in treating the EC and the treated effluent act as source of pollution to the water bodies. Considering the requirement of new technologies that can remove EC, the Constructed wetlands (CWs) are getting popular and can be a valid option for the treatment of EC. In this context application of macrophytes in CW have increased the removal performance of constructed wetland system. Growing macrophytes in CW have augmented the removal of EC from these systems. In different studies macrophytes supported the removal process of EC in CW and a removal efficiency up to 97% was achieved. This review summarizes the direct and indirect roles of macrophytes in CW in the treatment of EC. Also, it evaluates the success of CW technology, in treating EC, its limitation, and future perspective. The direct role of macrophytes include precipitation on root surface, absorption, and degradation of EC by these plants. Growth of macrophytes in CWs facilitates the uptake EC by the absorption and detoxify them in their cell with the help of enzymatic and hormonal activity which supports the removal of EC in wetland system. Indirect impacts, which appear to be more significant than direct effects, include increased removal of EC through better rhizospheric microbial activity and exudate secretions, which enhances the removal by four times. Thus, this review emphasizes combined application of CW and aquatic macrophytes which augmented the performance of CW for the treatment of EC.</p><h3 data-test=\"abstract-sub-heading\">Graphical Abstract</h3>\u0000","PeriodicalId":23640,"journal":{"name":"Wetlands","volume":"132 1","pages":""},"PeriodicalIF":2.0,"publicationDate":"2024-01-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139578195","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}

Painted turtle relative abundance was best estimated with the null model. We documented movement among wetlands for 22 snapping turtles (67%), including 10 females and 12 males. The probability of inter-wetland movement decreased with increased minimum distance from wetlands.

Because snowmelt runoff is the largest contributor to ponded water amounts, a seasonal change in precipitation timing, even when annual amounts are unchanged, can affect wetland hydroperiod. We observed a change in precipitation timing in the Alberta Prairie Pothole Region from 2014 to 2015, though cumulative precipitation amounts were near equivalent. We sought to understand whether this change in precipitation timing could result in (1) a decline in wetland hydroperiod and (2) a change in the community composition of birds, aquatic macroinvertebrates, and plants. Our findings suggest a change in precipitation timing occurred in 2015 (i.e., delayed-precipitation year), which could be tied to a decline in wetland hydroperiod. Wetlands in the delayed-precipitation year were dominated by upland birds and drought-adapted aquatic macroinvertebrates. There was no change in the community composition of plants, and we hypothesize that this may be explained by their ability to use energy stored from the previous year to survive this one-year change in their growing season.

Here we describe a common carp exclusion project on a large freshwater coastal wetland, Delta Marsh, in south-central Manitoba, Canada. Most fish species, including common carp, overwinter in Lake Manitoba and migrate each spring to feed and spawn in the marsh. Exclusion structures with removeable screens were installed on connecting channels between the lake and marsh and were deemed the best management option to exclude common carp from the marsh. In this paper we contrast relative abundance and mean size of large-bodied fish species between pre- (three years) and post- (six years) exclusion periods, as well as inside and outside the common carp exclusion zone. In addition, we monitored fish migration into the marsh to evaluate initial management recommendations. Using a combination of delayed exclusion screen placement and 70 mm screen openings, we were able to reduce the number of large common carp present in the marsh with minimal impacts on the native fish assemblage.

Legacy sediment removal (LSR) and floodplain reconnection (FR) involve removing anthropogenically derived sediment accumulated in valley bottoms to reconnect incised streams to their floodplains. These projects also present an opportunity to create high-quality riparian and wetland plant communities and provide information about the early stages of wetland vegetation development and succession. We surveyed vegetation immediately after restoration at three sites and at three additional sites 1–3 years post-restoration to determine how LSR/FR affects riparian plant communities. Restoration increased the prevalence of hydrophytic herbaceous species at all sites, suggesting these projects successfully reconnected the stream to the floodplain. Pronounced decreases in woody basal area and stem density likely also influenced an increase in native and graminoid species after restoration. Only 16% of the indicator species identified for restored reaches were planted as part of the restoration, suggesting the local seed bank and other seed sources may be important for vegetation recovery and preservation of regional beta diversity. Although vegetation quality increased after restoration in reaches with initially low-quality herbaceous vegetation, vegetation quality did not improve or decreased after restoration in reaches with higher-quality vegetation before restoration. The practice of LSR/FR has the potential to improve the quality of some riparian vegetation communities, but the preservation of high-quality forested areas, even if they are atop legacy sediment terraces, should be considered, particularly if reductions in nutrient export do not offset losses in tree canopy.</p>","PeriodicalId":23640,"journal":{"name":"Wetlands","volume":"3 1","pages":""},"PeriodicalIF":2.0,"publicationDate":"2024-01-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139509515","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 aimed to evaluate the effect of habitat features on the occupancy of mammals and birds in boreal wetlands, namely beaver ponds and peatland ponds. We used a multispecies occupancy model to estimate the habitat associations of 11 mammals and 45 avian species detected at 50 ponds during the summers of 2018 and 2019 in Northern Quebec. The patterns of habitat response do not lend support to the hypothesis that beaver ponds host higher levels of occupancy of birds and mammals than peatland ponds.
