Descrição

The dataset brings together all records of rotifers (Phylum Rotifera) found by N. Iakovenko and D. Lukashanets worldwide in limno-terrestrial habitats – substrates that periodically undergo cycles of desiccation and hydration but cannot be classified as temporary waterbodies – such as mosses, lichens, fungi, timber, upper layers of soil, and litter.

From 1996 to the present, we have collected and analysed more than 2,160 limno-terrestrial samples. Sampling covered all continents and over 50 countries, spanning from the Arctic to the Antarctic, including most of major biomes. The altitude of sampling sites ranged from 0 to 4,610 m above sea level. In total, the dataset includes 5,294 records of limno-terrestrial rotifers. We found 207 clonal species (including nominal ‘subspecies’ that in bdelloids are to be updated to species in future) belonging to 23 genera (9 of Monogononta and 14 of Bdelloidea). More than other 300 species-level entities were different in minor or major details from the original descriptions and potentially might be new taxa.

The submitted dataset is extensive and substantially contributes to the current knowledge of diversity and distribution of limno-terrestrial rotifers subject that is still poorly known, especially outside Europe. We present it for the wider use in studies of microinvertebrate biodiversity and macroecology.

Cobertura Taxonômica

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.

Dados Sobre o Projeto

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.

Título ROTISFERA 'Global patterns of microinvertebrate distribution: does diversity decrease poleward in rotifers (Rotifera: Bdelloidea)?’
Identificador NDICI-GEO-NEAR/2022/434-092-0068
Financiamento European Union
Descrição da Área de Estudo The project covers all regions of the Earth.
Descrição do Design To address project's aim we used samples collected starting from 1996 until present in limno-terrestrial habitats throughout the world. More than 2,000 samples were analyzed using conventional methods (analysis of rotifer morphology using light microscopy) resulting in creation of dataset with 5,295 rotifer species occurrences, 98.5% of which belong to bdelloids. The data covers all continents, including both polar zones and ranging from 0 to 4,610 m of altitude. The further steps include estimation of the diversity patterns within defined geographical area (alpha- and gamma-diversity, rarefaction curve, asymptotic diversity estimates), and globally, i.e. revealing shape and prominence of latitudinal diversity gradient using hexagonal model and general additive model (GAM). In parallel, the diversity of limno-terrestrial rotifers will be assessed using molecular approach. It is planned to imply metabarcoding sequencing of coI mitochondrial gene for rotifers, however, not in global scale (only Europe - from Mediterranean to Arctic). Results obtained using both methodological approaches will be compared.

Métodos de Amostragem

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.

Área de Estudo All samples used in the dataset were collected either within the frame of several research projects focused on the biodiversity and ecology of microfauna, or as a part of other field activities. The latter included fieldwork in remote and hard-to-reach areas (tropical rainforests, polar and alpine regions), visiting notable places, incidentally in field trips, within national Antarctic expeditions, during landing at cruises of research vessels, etc. The samples have been stored in the repositories of the dataset’s main creators, Dr. Nataliia Iakovenko and Dr. Dzmitry Lukashanets. For the short-term storage we used gradual drying at room temperature, while for long-term preservation freezing at -20-25° C was used (samples from other than polar latitudes were first gradually dried at room temperature before freezing).
Controle de Qualidade Two recognized specialists in taxonomy of Bdelloidea rotifers, Dr. Nataliia Iakovenko and Dr. Dzmitry Lukashanets, carried out all species identification while consulting other specialists (Dr. Diego Fontaneto, Dr. Aydin Örstan). Primarily first descriptions together with the existing identification keys and reviews on the taxonomy of bdelloids were used. Georeferenced data were checked by placing latitudes and longitudes on a map.

Descrição dos passos do método:

  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.
