However, obtaining such information can be challenging, particularly in remote areas with limited data. This study presents a way to leverage inundation frequency and ICESat-2 photon-counting LiDAR data to develop bathymetric models for Ramsar-listed lakes in a semi-arid region of Australia. Based on developed bathymetric models, monthly time series of water areas, levels and volumes were derived, providing a long-term view of the water dynamics of the two lakes from1987-2021. This is the first time that such detailed bathymetry and long-term water dynamics have been established for Ramsar-listed lakes in Australia's Outback. The findings of this study provide the most up-to-date information on the long-term trends of the Ramsar-listed lakes in the region and highlight the lakes’ prolonged dry spells when drought conditions prevailed through much of the 2000s and the 2010s as denoted by rainfall deficiencies and high evaporation. The outcome of this study serves as a valuable baseline for understanding the historical and ongoing status of these Ramsar-listed lakes in a warming and drying climate and contributes to the development of strategic plans to fulfill international obligations for wetland protection under the Ramsar Convention.</div></div>","PeriodicalId":56070,"journal":{"name":"Ecohydrology & Hydrobiology","volume":"25 1","pages":"Pages 10-22"},"PeriodicalIF":2.7,"publicationDate":"2025-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135760265","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The ecosystem experiences temporary shifts between freshwater and brackish water due to the seasonal influx of freshwater from the river during winter and spring, and the substantial inflow of brackish water during summer and autumn. The seasonal changes of plankton in the bay were driven by several factors, among which the most important were water temperature, periodic brackish water inflow, and development of aquatic vegetation. After winter, phytoplankton began to develop first (March), followed by rotifers (April) and crustaceans (May). At the beginning of summer, zooplankton biomass decreased, which could favored the development of phytoplankton, however, the intense growth of algae was limited by shading by plant canopies and nutrient competition between macrophytes and phytoplankton. The development of vegetation was accompanied by an increase in the species richness and diversity of crustacean zooplankton with many plant-associated species. The results of our research indicate that the periodically changing habitat complexity (macrophytes, salinity) in the estuary bay limits the intense development of plankton but increases its diversity.</span></div></div>","PeriodicalId":56070,"journal":{"name":"Ecohydrology & Hydrobiology","volume":"25 1","pages":"Pages 215-224"},"PeriodicalIF":2.7,"publicationDate":"2025-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140405074","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}
