Testate Amoebae (Amebozoa: Arcellinida) in Tropical Lakes of Central Mexico.
Testate amoebae are common single-celled eukaryotic organisms in aquatic ecosystems. Despite their important role in these ecosystems, and their potential as bioindicators and paleoindicators, they remain poorly studied in Mexico. The major objectives of this study were to: 1) increase knowledge of testate amoebae in Mexico’s tropical lakes, and 2) create a catalog of high-quality scanning elec...
متن کاملThe testate lobose amoebae (order Arcellinida Kent, 1880) finally find their home within Amoebozoa.
Testate lobose amoebae (order Arcellinida Kent, 1880) are common in all aquatic and terrestrial habitats, yet they are one of the last higher taxa of unicellular eukaryotes that has not found its place in the tree of life. The morphological approach did not allow to ascertain the evolutionary origin of the group or to prove its monophyly. To solve these challenging problems, we analyzed partial...
متن کاملA Critical Review of Arsenic Contamination in Sri Lankan Foods
Numerous studies have shown growing information indicating the contribution of food to the dietary exposure of arsenic (As) through consumption of different food items in many different regions over the world. However, few review papers with regard to As in Sri Lankan foods are available in databases. Thus, a critical review and assessment of a number of local studies on total As concentrations...
متن کاملHydroecology of Amazonian lacustrine Arcellinida (testate amoebae): A case study from Lake Quistococha, Peru.
Organic rich sediments were obtained from seven core tops taken in Lake Quistococha, near the city of Iquitos in the Peruvian Amazon. Subsamples from 0 to 4cm depth in each core were analyzed under dissecting light microscopy to carry out the first investigation of Arcellinida (testate lobose amoebae) from a lacustrine environment in this ecologically important region. The fauna was characteriz...
متن کاملPhosphate supply as a promoter of tolerance to arsenic in pearl millet
Many soils are contaminated by heavy metals, with arsenic posing serious environmental threat. Enrichment of soil with phosphate is believed to reduce the arsenic toxicity. However, only a few attempts have already been conducted towards understanding the precise role of phosphate in controlling As toxicity. Moreover, there is no adequate information on the effect of phosphate on As-induced...
