Abstract

This dataset presente the distribution of testate amoebae in São miguel island (Azores archipelago)

Keywords: Testate amoebae, Azores, oceanic islands, new records, Testate amoebae, Azores, oceanic islands, new records

Project details

Project title: Records of testate amoebae in São Miguel island (Azores archipelago)
Personnel: Martin Souto
Funding: This work was funded by FCT– Foundation for Science and Technology (DL57/2016/ICETA/EEC2018/25).
Study area descriptions/descriptor: São Miguel Island (Azores Archipelago) is an oceanic island located in the
middle of the North Atlantic about 1500 km off Portugal mainland.
Design description: Testate amoebae collections were taken at the beginning of the growing season, between spring (February - March) and summer 2020 (May - June). In each location several types of vegetation were chosen for their homogeneity and abundance [e.g., forest, lowland shrub, shrubland, wetland, peatland, riparian communities and within these communities the most abundant bryophytes were sampled. In each subsampling site, three homogeneous subplots (10 × 10 cm) were chosen, defining a total 138 sampling points.

Methods

Method step description: 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.
Study extent description: The samples were taken at the beginning of the growing season in spring 2020 (february - march) and summer 2020 (may - june). In each location several types of vegetation were chosen for their homogeneity and abundance (forest, lowland shrub, shrubland, wetlands, peatland, riparian communities, etc) and within these communities the most abundant bryophytes were sampled. Testate amoebae communities were examined in 60 sites (each site, we chose 3 homogeneous subplot (10 X 10 cm) in total 180 sampling points.
Sampling description: Testate amoebae were collected by washing 10 X 10 cm of a wet mass of plant material. The soil was dominated by silt sized particules derived from pyroclastics, because of this, they tried to collect only the vegetable part, the top layer of mosses.
