Records of testate amoebae in São Miguel island (Azores archipelago)

Study Extent

Sampling

Method steps

1. To isolate the testate amoebae shells, the mosses were fragmented, washed and stirred in one l of distilled water and then sieved through a 300 μm mesh size to separate large moss particles. The samples were condensed by the sedimentation method and the samples stored in vials with alcohol 50% at 4°C. A small sample from each site of study were stored as reference collection. A drop of each sample was mounted on a semi-permanent slide and all tecamebas were counted and identified at ×200 and ×400 magnification. Microphotographs were taken by a Leica DFC495 camera attached to a Leica DM2500 light microscope with the aid of image analysis software (Leica Application Suite version 3.8.0). The systematics of the taxa are given in accordance with Ogden & Hedley (1980). Accepted names and authorities for vascular plants and bryophytes were checked in http://www.theplantlist.org. (June 2020). The taxa are listed in alphabetical order and major taxonomic groups, together with their brief descriptions, habitats, localities, collection dates, and accession numbers.
