Checklist, diversity and distribution of testate amoebae in Chile.
Bringing together more than 170 years of data, this study represents the first attempt to construct a species checklist and analyze the diversity and distribution of testate amoebae in Chile, a country that encompasses the southwestern region of South America, countless islands and part of the Antarctic. In Chile, known diversity includes 416 testate amoeba taxa (64 genera, 352 infrageneric tax...
متن کاملTestate 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 کاملProgress and prioritizing needs for future research on testate amoebae: a meeting report on the International Symposium on Testate Amoebae, Antwerp, Belgium, September 12-14, 2006.
An international group of 44 scientists from 16 countries assembled at the University of Antwerpen to share experiences and assess current research progress concerning testate amoebae. It had been 23 years since the last testate amoebae workshop was held in Aachen, Germany and 30 years since the first testate amoebae workshop before it was organized in 1976 in Sofia, Bulgaria. Interest in testa...
متن کاملVertical micro-distribution and response to nitrogen deposition of testate amoebae in Sphagnum.
Previous studies have shown the existence of a vertical micro-distribution of testate amoebae in the first centimeters of Sphagnum and their response to nutrient enrichment. In order to test the response of testate amoebae to depth and N addition in dry moss carpets recolonizing cutover peatlands, we sampled Sphagnum that had received 0, 1, 3, or 10g N m(-2) yr(-1) for three years. The mosses w...
متن کاملEffect of lead pollution on testate amoebae communities living in Sphagnum fallax: an experimental study.
We studied the effects of lead pollution on testate amoebae communities living on Sphagnum fallax by growing this moss under controlled conditions. A progressive series of lead (Pb) concentration was used in the growing solution of the mosses: 0 (control), 625 and 2,500 microgL(-1). The mosses were sampled and analysed for accumulated Pb and testate amoeba communities after 0, 6, 12, and 20 wee...
