Aquatic weeds are widely used as animal feed in developing countries. However, information about element bioavailability from these plants is lacking. A combination of an in vitro method [physiologically based extraction test (PBET)] and an in vivo feeding trial was used in this study to investigate potential element bioaccessibility and estimated bioavailability of Pistia stratiotes (PS). Cu, ...

Currently additional sustainable ways to mitigate the degradation of water quality are being researched all over world. Phytoremediation is one serious efforts towards sustainability. The main objective this study was assess rhizofiltration potential lettuce (Pistia stratiotes), common duckweed (Lemna minor) and mosquito fern (Azolla pinnata) on removal total ammonia-nitrogen (TAN) in circular ...

This paper reports on a study to determine the Hg content in the five most abundant aquatic macrophyte species (Elodea densa, Sagittaria montevidensis, Salvinia auriculata, Pistia stratiotes and Eichhornia crassipes) in two artificial reservoirs flooded by water diverted from the Paraíba do Sul river, SE Brazil. The potential of these species for Hg accumulation and their role in Hg transport a...

The present study discussed the kinetic aspects of leachate decomposition from an aquatic macrophyte, Pistia stratiotes L (water lettuce). This species was collected from Barra Bonita Reservoir located in the State of São Paulo (Brazil). Decomposition chambers were prepared with high molecular weight (HMW), low molecular weight (LMW) and integral (INT = HMW + LMW) dissolved organic matter (DOM)...

Ammonium Preference: Agrostis canina (velvet bentgrass) Amphibolis antarctica (a seagrass) Callitriche hamulata (a water starwort) Ceratophyllum demersum (hornwort) Cymodocea rotundata (a seagrass) Drepanocladus fluitans (an aquatic moss) Eichhornia crassipes (water hyacinth) Elodea densa (Anacharis) Elodea nuttallii (Western waterweed) Fontinalis antipyretica (willow moss) Halodule uninervis (...

Performance of the specialist herbivore Spodoptera pectinicomis (Hampson) was studied when fed the floating aquatic plant waterlettuce, Pistia stratiotes L. (Araceae). Plants were either collected from 6 populations in southern Florida or from plants grown with low or high fertilizer levels. Consumption of leaves with increasing toughness resulted in increased larval mortality (>80%); most mort...
