Aquatic macrophytes

Ebook "Freshwater animal diversity assessment" gives a state of the art assessment of the diversity and distribution of Metazoa in the continental waters of the world. The project deals with all major animal groups plus the macrophytes, and encompasses the complete array of terrestrial aquatic ecosystems. It is the most comprehensive study of species- and genus-level diversity and chorology of the global freshwater fauna to date, and is the first to present comparable data on the different faunal groups concerned.

The antibacterial agent triclosan (TCS) is added to many daily-used consumer products and can therefore reach the aquatic environment via treated wastewater and potentially harm aquatic ecosystems. A 120 days pond mesocosm study was conducted in order to investigate the fate of TCS in water and sediment, its bioaccumulative potential in different biota as well as the effects of TCS and its main transformation product methyl-triclosan (MTCS) on plankton, periphyton, macrophytes, and benthos communities.

Aquatic macroinvertebrates have a close relationship with associated floating macrophytes, especially with the roots. The plant root mass is an environment favorable to the development of the macroinvertebrate fauna, supplying both food resources and refuge against predators. The present study aimed to analyze the structure of the macroinvertebrate community associated with the roots of Eichhornia azurea (Sw.) Kunth (Pontederiaceae) in a lake marginal to a tropical river. Sampling was performed quarterly in three stands of E. azurea.

Aquatic macrophytes are one of the key components of freshwater ecosystems and contribute to ecosystem functioning and environmental sustainability. They are assumed to be an ideal biomonitoring tool in long-term monitoring programs implemented by the EU Water Framework Directive due to their sensitivity to environmental factors. Therefore, this study focuses on the evaluation of the ecological status in Lake Sapanca using macrophyte composition and abundance in order to make future predictions on the health of aquatic ecosystems and to form effective management.

Cauvery river system is one of the major freshwater aquatic systems in Peninsular India with a number of tributaries and reservoirs on it. The system inhabits a variety of endemic fish species. Thippagondanahalli Reservoir (TR) is a medium reservoir on Arkavathy River, a tributary of River Cauvery. This report is on the first record of dwarf gourami, Trichogaster lalius belonging to the family, Osphronemidae, from the TR. The reservoir is located in Bengaluru South Taluk, Karnataka [13⁰ 02’41”N 77⁰ 36’24”E; Area at FRL (Full Reservoir level): 1162.0 ha].

Duckweed (Lemna minor L. Lemnaceae) is a widespread, free-floating aquatic macrophyte, a source of food for waterfowl and a shelter for small aquatic invertebrates. It grows quickly and reproduces faster than other vascular plants.
