地理的範囲

The dataset includes records collected throughout the world, spanning latitudes from 77.94° S to 78.28° N and covering all continents: (i) Europe – Austria, Belarus, Belgium, Bulgaria, Croatia, Czech Republic, Denmark, Estonia, Finland, France, Germany, Great Britain and Northern Ireland, Hungary, Italy, Latvia, Lithuania, Montenegro, Netherlands, North Macedonia, Norway, Poland, Portugal, Russia (Karelia and Caucasus), Serbia, Slovakia, Spain, Sweden, Switzerland, Ukraine; also including the European Arctic (Bear Island, Iceland, Jan Mayen, Svalbard) and Mediterranean islands (Mallorca, Malta, Pantelleria, Sardinia); (ii) Asia – Armenia, Brunei, China, Cyprus, Georgia, Japan, Kyrgyzstan, Malaysia, Myanmar, Nepal, Russia (Southern Siberia), Taiwan, Tajikistan, Turkey; (iii) Africa – Democratic Republic of Congo, Lesotho, Tunisia; also including Macaronesia (Madeira); (iv) North America – western Greenland, USA (contiguous states and Alaska); also including the Caribbean (Martinique); (v) South America – Brazil, Chile; (vi) Australia and Oceania – Australia (mainland and Tasmania), New Zealand, Papua New Guinea; (vii) Antarctica – Antarctic Peninsula, Argentine Islands, Queen Maud Land, Enderby Land, James Ross Island, King George Island, Victoria Land.

生物分類学的範囲

The dataset includes all records belonging to Phylum Rotifera, which we found in the samples of soil, moss, lichen and other limno-terrestrial habitats. Monogonont rotifers (order Ploima) accounted for only 1.47 % the records, whilst the majority of records were bdelloids (order Bdelloidea). Species with uncertain affiliation or potentially new for science were indicated as Genus sp., those different from the nominal description (mostly potentially new) are designated as cf.

プロジェクトデータ

The project deals with the Latitudinal diversity gradient (LDG), which is one of the important biodiversity structural characteristics that in its initial concept refers to the quantitative changes (increase or decrease) of species richness from the poles to the equator. In most terrestrial macroorganisms LDG is characterized by higher diversities near the equator, while aquatic species tend to increase diversity toward the poles. However, for the microfauna, especially for so-called limno-terrestrial organisms (inhabitants of wet soil, moss and lichens), the presence and shape of LDG are still unclear. The main aim of the proposed project is to estimate the prominence and shape of global LDG in limno-terrestrial bdelloid rotifers (Bdelloidea; Rotifera). The general strategy of the project implies the employment of both conventional and metabarcoding techniques (extraction and sequencing of total DNA from the already collected frozen soil and moss samples) to estimate diversity metrics and compare them. Secondary, the project aims at inventarization of rotifer biodiversity in less studied studied regions, especially in Arctic and Antarctic. Two European Universities are involved in the project: Klaipeda University (KU) as lead applicant and Czech University of Life Sciences Prague (CZU) as co-applicant.

収集方法

For the analysis of limno-terrestrial rotifers, sampling was performed mainly in forest ecosystems (taiga, boreal and mixed forests, subtropical forests, tropical rainforests), flatlands, urban areas, and agricultural landscapes. In polar areas, we conducted sampling in moss tundra, at post-glacial moraine, in Antarctic oases and nunataks. Samples of soil and litter were collected using 3.8 cm metal corer or metal scoops. Lichens, mosses, and other vegetation were picked from the ground, tree barks, and stones using tweezers or simply by hands. The size of the samples varied from a few cm3 to several dozen cm3, depending on the amount of material available for collection. All samples were placed in paper of plastic bags and properly labelled. All sampling sites were georeferenced.

Method step description:

1. Microscopic animals were isolated from each sample. For this, soil particles, litter, or pieces of vegetation with a total volume of 25 cm3 (or less if the sample volume was insufficient) were washed on metal sieves, followed by flotation and centrifugation in a sugar solution (Freckman, Virginia, 1993). Alternatively, the method for extracting moss-dwelling rotifers described by Peters et al. (1993) was used.
2. Rotifers were counted and sorted under a binocular microscope (Olympus SZ61, Olympus SZX10, NR.3 Nikon SMZ1000).
3. For species identification, live rotifer individuals were transferred to slides and examined using light microscopy (Nikon Eclipse Ts2R, NIB-100F inverted microscope, Olympus CX43). First descriptions of taxa and the existing identification keys were used: Donner (1965), Bartoš (1951, 1959), Kutikova (2005). Body dimensions and proportions were measured following the protocol of Iakovenko et al. (2013, 2015).
4. All rotifer densities are counted as individuals per standard volume of 25 cm3 (estimated empirically as the most convenient for handling both rich and individual-scarce samples). For samples with smaller or higher volumes, the obtained counts were re-calculated to the standard volume.
