Abstract: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 electron micrographs that can be used for future ecological and paleoenvironmental studies. We collected surface-sediment samples from 29 lakes, located in the Transmexican Volcanic Belt, one at each lake during June and October 2011, and March 2013. Sediments were collected with an Ekman grab and preserved in anhydrous ethanol. Sub-samples were observed under a stereomicroscope and morphometric data for each species were recorded. Total diameter and aperture diameter were measured on circular tests. Irregularly shaped tests were measured for length and width of the aperture and for the size of the whole test. If a specimen possessed spines, the length of one randomly selected spine was measured. The best-preserved specimen of each taxon was photographed with an optical microscope and a scanning electron microscope (SEM). We found 41 taxa of testate amoebae belonging to the genera: Arcella, Argynnia, Centropyxis, Cucurbitella, Cyclopyxis, Cyphoderia, Difflugia, Euglypha, Lesquereusia, Pentagonia, Pseudodifflugia and Scutiglypha. Twelve species not previously reported for Mexico were recorded, along with 13 varieties. The average number of taxa recorded in each lake was eight, and the highest taxonomic richness was 18. The taxon found in the greatest number of lakes was Centropyxis aculeata var. aculeata. Taxonomic richness varied among lakes in the same region. This could reflect lake-specific differences in environmental conditions, underscoring the need for more detailed studies that include collection of data on physical and chemical variables in the lakes. Our results highlighted the need of further studies for the distribution patterns and ecology of lacustrine testate amoebae. Rev. Biol. Trop. 64 (1): 377-397. Epub 2016 March 01.

The species composition of testate amoebae was studied for the first time in the northern and central parts of Israel. One hundred and eight species and infra-species taxa of Testacea belonging to 18 genera and 10 families were identified in 68 samples. The materials were collected along a transect in the Mediterranean phyto-geographical region of Israel, from Mt. Hermon 2100 m above sea level (part of the Anti-Lebanon Mt. Ridge), to the Sea of Galilee 200 m below sea level to the Mediterranean sea shore near Tel Aviv. All the species identified are Holarctic, most of them cosmopolitan. Some of the sampled testaceans require additional taxonomic studies and are possibly new species endemic to the country. A low α-diversity index was demonstrated for the specimens collected in the humid and swampy habitats, while the majority of the species assemblages, mainly eury-bionts, were similar among habitats.
