Abstract

Invasive aquatic plants are considered the second cause of biodiversity loss in aquatic ecosystems. Pontederia crassipes Mart., formerly Eichhornia crassipes (Mart.) Solms (water hyacinth) is one of the most dangerous invasive species in the world. Since 2006, P. crassipes has invaded Lebanon’s Al Kabir River, causing ecological and socio-economic problems. To solve them, ecological and biological characteristics are important to understand the water hyacinth response to variations in environmental conditions. The aims of this study were (i) to analyze P. crassipes growth and (ii) physico-chemical parameters at two sites and (iii) to determine ecological relationships between P. crassipes and other plant species. The main results show the existence of different cohorts of water hyacinth at the two sites. Differences in growth between these cohorts are likely due to physico-chemical differences. In addition, P. crassipes coexist with other invasive and native plants. This ecological study can help ecologists and stakeholders map invasive plants in rivers and improve their control.

黎巴嫩地中海河流中庞德属植物的生物学和生态学

入侵水生植物被认为是水生生态系统生物多样性丧失的第二大原因。Pontederia crassipes Mart。，原为Eichhornia crassipes (Mart.)水葫芦是世界上最危险的入侵物种之一。自2006年以来，P. crassipes入侵了黎巴嫩的Al Kabir河，造成了生态和社会经济问题。为了解决这些问题，生态和生物学特性对于了解水葫芦对环境条件变化的响应至关重要。本研究的目的是:(1)分析两个地点的石楠生长情况和(2)理化参数;(3)确定石楠与其他植物之间的生态关系。主要结果表明，两个地点的水葫芦存在不同的种群。这些队列之间的生长差异可能是由于物理化学差异。此外，石楠与其他入侵植物和本地植物共存。这项生态学研究可以帮助生态学家和利益相关者绘制河流中入侵植物的地图，并改善对它们的控制。

期刊介绍： Aquatic Botany offers a platform for papers relevant to a broad international readership on fundamental and applied aspects of marine and freshwater macroscopic plants in a context of ecology or environmental biology. This includes molecular, biochemical and physiological aspects of macroscopic aquatic plants as well as the classification, structure, function, dynamics and ecological interactions in plant-dominated aquatic communities and ecosystems. It is an outlet for papers dealing with research on the consequences of disturbance and stressors (e.g. environmental fluctuations and climate change, pollution, grazing and pathogens), use and management of aquatic plants (plant production and decomposition, commercial harvest, plant control) and the conservation of aquatic plant communities (breeding, transplantation and restoration). Specialized publications on certain rare taxa or papers on aquatic macroscopic plants from under-represented regions in the world can also find their place, subject to editor evaluation. Studies on fungi or microalgae will remain outside the scope of Aquatic Botany.
