EwE files for: From phytoplankton to the Murray cod: modelling the Murray River’s food web

Ecopath with Ecosim files from the report:Hitchcock JN, McInerney PJ, Zampatti B and Rees G (2025) ​From phytoplankton to the Murray cod: modelling the Murray River’s food web​. Flow-MER Program. Commonwealth Environmental Water Holder: Flow Monitoring, Evaluation and Research Program, Department of Climate Change, Energy, Environment and Water, Canberra, Australia.The food web models were constructed for 4 reaches of the Murray River, encompassing 2,152 km of river channel from the Hume Dam in New South Wales downstream to Wellington in South Australia. Models were built for a 45-year period and used a mixture of historical and recent data, as well as knowledge from the literature detailing taxa biomass, diets and flow–ecology relationships.The CEWH’s Flow-MER program examines the contribution of Commonwealth environmental water to the environmental objectives of the Basin Plan 2012 (Basin Plan) and is assisting the CEWH to demonstrate environmental outcomes and adaptively manage the water holdings. Monitoring and evaluation is focused in seven Selected Areas: the Junction of the Warrego and Darling rivers, Gwydir river system, Lachlan river system, Murrumbidgee river system, Edward/Kolety-Wakool river system, Goulburn River and Lower Murray River.For more information: https://flow-mer.org.au/basin-theme-food-webs-water-quality/

本数据集包含来自下述报告的生态通道与生态模拟（Ecopath with Ecosim）模型文件：作者为Hitchcock JN、McInerney PJ、Zampatti B与Rees G，于2025年发表的《从浮游植物到墨累鳕鱼：墨累河食物网建模》。该数据集隶属于Flow-MER计划（流量监测、评估与研究计划），即澳大利亚联邦环境水持有者（Commonwealth Environmental Water Holder, CEWH）下属的气候变化、能源、环境与水资源部流量监测、评估与研究计划，办公地点位于澳大利亚堪培拉。

本研究构建的食物网模型覆盖墨累河的4个河段，河道总长2152公里，范围从新南威尔士州休姆大坝至南澳大利亚州惠灵顿。模型构建周期为45年，整合了历史与近期实测数据，以及已发表文献中关于各类群生物量、食性及流量-生态关系的研究成果。

CEWH的Flow-MER计划旨在评估联邦环境水对《2012年流域计划》（Basin Plan）环境目标的贡献，并协助CEWH论证环境效益、对水资源持有量进行适应性管理。该计划的监测与评估工作聚焦于7个重点区域：沃雷戈河与达令河交汇处、吉德河水系、拉克兰河水系、默伦比奇河水系、爱德华/科莱蒂-瓦库尔河水系、古尔伯恩河以及墨累河下游河段。
