Precipitation, as a primary influencing factor, has garnered significant attention. AimsThis study is based on precipitation data to investigate the spatiotemporal characteristics of precipitation in the middle and lower reaches of Yangtze River Basin (MLYB), trying to explore more concise methods for precipitation forecasting. MethodsStatistical methods were employed to analyse historical precipitation patterns, followed by forecasting future trends using statistical time series models. Key resultsPrecipitation in the MLYB exhibited a decreasing trend during 1961–2010, which shifted to an increasing trend after 2011, becoming more pronounced since 2017. Precipitation patterns in the MLYB were clearly increasing in the east and decreasing in the west, with the Taihu Basin showing the greatest rise. The ARIMA model predicted a significant increase in precipitation after 2022. ConclusionsIn recent years, precipitation in the MLYB has significantly increased, especially in downstream areas. Although the ARIMA model offers an effective and reasonably simple method for short-term forecast, it struggles with complex terrain influences. ImplicationsThese findings provide a theoretical basis for flood prevention in the MLYB, as well as a reference for precipitation prediction simulations in data-limited regions.","PeriodicalId":18209,"journal":{"name":"Marine and Freshwater Research","volume":"26 1","pages":""},"PeriodicalIF":1.8,"publicationDate":"2024-08-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141949348","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}

AimsWe aimed to increase learning-related understanding required for effective adaptive management of water for the environment, in water-stressed and contested river systems. MethodsWe developed a learning approach (requisite learning) for managing water for the environment, demonstrated with real-world examples from the Macquarie River and Marshes, Australia. Key resultsFour co-existing, interdependent learning types enable effective management of water for the environment: (1) ‘adjusting routines’, (2) ‘adaptive assessment’, (3) ‘changing practice’, and (4) ‘transforming governance’, exemplified by using management of water for the environment for the Macquarie River and Marshes. To enable and improve requisite learning, stakeholder social learning, and flexibility in governance arrangements, must develop. ConclusionsOngoing learning is essential for effective adaptive management. Understanding what requisite learning is and how capacity can be improved, will help achieve outcomes required of managing water for the environment. ImplicationsEffective management of water for the environment is essential, transparently delivering environmental outcomes and accounting for decision-making. To do this, we need to improve explicit learning understanding by nurturing learning mandates and champions, fostering social learning, increasing flexibility in governance arrangements, and institutionalising learning.","PeriodicalId":18209,"journal":{"name":"Marine and Freshwater Research","volume":"29 1","pages":""},"PeriodicalIF":1.8,"publicationDate":"2024-08-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141949346","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}

AimsWe investigated the reproductive phenology of Eucalyptus camaldulensis and Eucalyptus coolabah to better understand tree reproductive cycles and the influence of rainfall and flow on seed production. MethodsWe surveyed phenological events (bud, flower and fruit production) over 6 years, at nine sites along the Condamine–Balonne River and examined correlations between these events and meteorological parameters. Key resultsFor both species, event timing was consistent across sites and years and event relative abundance scores were different between years. Bud abundance was correlated with rainfall, flooding and warming temperatures and E. coolabah produced additional bud crops after floods. ConclusionsThe timing of events did not differ significantly from published results for the southern MDB. Rainfall, river flows and flooding in spring resulted in more abundant bud crops in E. camaldulensis and E. coolabah, and subsequently more abundant fruit crops. Fruit dehiscence coincided with summer–autumn flooding, which provides seed for germination. Genetic and physiological factors may also influence the observed pattern.

MethodsLipid and fatty acid compositions in the gills and digestive glands of mussels were analysed by chromatography. Key resultsMembrane-state fatty acid indices in phospholipids were quite stable in all the mussels examined. The fatty acid composition of triacylglycerols is primarily an indicator of the food source for mussels. The selective retention of arachidonic acid as well as the accumulation of non-methylene-interrupted fatty acids in mussels are assumed to be biomarkers of environmental stress. ConclusionsThe presence of regulatory mechanisms ensuring the stability of the membrane structure was confirmed in all studied mussels.

Over time, T. gigas natural spawning area has gradually diminished owing to human and natural causes. T. gigas is being artificially bred in captivity to enhance its population. AimsThe study aims to determine the T. gigas spawning preference for three different sediment sizes. MethodsSpawning experiments were carried out in an indoor concrete tank representing an artificial spawning ground, consisting of three combinations of sediment sizes: coarse, medium and fine. The spawning of 45 pairs of T. gigas samples was observed within 3 h, the nests were marked and excavated on the next day. The number of eggs per nest was counted individually after being cleaned. Key resultsThe 45 pairs of T. gigas produced 27,266–30,859 eggs. Among these, on the basis of the number of nests produced, T. gigas prefers to spawn in medium to coarse sediment with a particle-size range of 0.25–1.00 mm. ConclusionsOur findings indicated that medium to coarse sediments are optimal for T. gigas spawning in artificial spawning grounds, because they could produce a high number of nests and eggs, increasing the number of juveniles released. ImplicationsThese results could be used as a baseline for the conservation management of T. gigas in captivity.","PeriodicalId":18209,"journal":{"name":"Marine and Freshwater Research","volume":"75 1","pages":""},"PeriodicalIF":1.8,"publicationDate":"2024-07-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141886186","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}

MethodsWe employed open-sampling questionnaires and semistructured interviews to collect data and conducted multivariate analysis. Key resultsThe study investigated the hypothesis that optimising water-conservancy projects for lake tourism creates a stable leisure and tourism environment in rural areas, enhances visibility, and increases emotional exchanges and the preservation of historic sites. However, problems such as excessive tourism waste and a lack of public facilities negatively affect local young consumers’ willingness to engage in tourism activities. ConclusionsImproving problems in the villages, ecology and natural environment surrounding lakes that are being conserved can increase young local individuals’ willingness to engage in and share experiences of tourism activities.

Without the macrophytes, wave action resuspends lakebed sediments, and a feedback loop is set up, trapping the lake in a degraded state. Multiple restoration actions are required to reverse this process, including catchment management and in-lake actions to remove barriers to establishing native vegetation. In particular, when macrophytes have been lost for a long time, the native seedbank may be depauperate and limit re-establishment opportunities. Re-establishment of submerged vegetation is critical to the restoration of lakes, but to date there have been few efforts to actively do this. There are significant barriers preventing this goal, relating to poor water quality, low-density sediments and the browsing impacts of fish and waterfowl, that will be further exacerbated by the warmer temperatures and more extreme weather events forecast under climate change. A combination of experimental and field studies determining optimal environmental ranges of different macrophyte species, methods to culture en masse and techniques to promote sufficient water clarity and sediment density to sustain macrophytes are necessary. Once minimum vegetation cover thresholds are exceeded, sustainable restoration to a macrophyte-dominated clear-water state should eventuate.","PeriodicalId":18209,"journal":{"name":"Marine and Freshwater Research","volume":"139 1","pages":""},"PeriodicalIF":1.8,"publicationDate":"2024-07-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141572686","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 the short-term, rapid responses of wetland biota and ecological processes to wetting and drying, which influence ecosystem structure and function, enable rapid reproduction which enhances long-term resilience. However, over longer periods, mechanisms such as seed dormancy and persistent seed and egg banks enable dryland wetland ecosystems to recover after major environmental perturbations such as mega-droughts or wildfire. Climate change is likely to have a significant effect on key drivers of ecological response in dryland wetlands, including hydrology and its interface with other climatic stimuli, e.g. temperature, as well as the frequency and intensity of extreme events. Like species, wetland ecosystems may respond to climate change in three main ways, namely, disappear, persist without significant adjustment, or transform. Here, we consider the conditions under which each of these responses may eventuate for dryland wetlands, by using wetland vegetation of the northern Murray–Darling Basin Australia, as a case study. We also explore what wetland transformation might entail in this region in terms of wetland ecological character and the key values this supports. Finally, we consider the implications for wetland policy and management at present and as trajectories of wetland change unfold.","PeriodicalId":18209,"journal":{"name":"Marine and Freshwater Research","volume":"71 1","pages":""},"PeriodicalIF":1.8,"publicationDate":"2024-07-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141572690","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}
