| Abstract |
To make oribatid mites an applicable tool in monitoring programs it is necessary to find a molecular species marker that allows distinct, rapid and easy species identification. In previous studies, the common barcoding sequence COI showed to be too variable to serve as species marker in oribatid mites. The aim of the present study is to evaluate the potential use of the D3 region of the nuclear 28S rDNA gene for species identification. Therefore, we generated a reference DNA library of 28S D3 to identify specimens of the Oribatida from Germany, with focus on species occurring in peatlands being one of the most endangered habitats in Europe. New DNA sequences were obtained from 325 individuals and 64 species (58 genera, 34 families). By adding 28S D3-sequences from GenBank we altogether analysed 385 sequences from 89 German species, 32 of them restricted to peatlands and further 42 occurring in peatlands occasionally, representing 46 and 33% of the oribatids in German peatlands, respectively. P-distances were measured between species within families as well as for intraspecific divergence. 28S D3 showed low intraspecific genetic p-distances between 0 and 0.5%, interspecific distances within families varied between 0 and 9.7%. Most species pairs within families were further separated by one to four indels in addition to substitutions. Altogether, 93% of all analysed species are clearly delineated by 28S D3. Our study emphasises that 28S D3 rDNA is a useful barcode for the identification of oribatid mite specimens and represents an important step in building-up a comprehensive barcode library to allow metabarcoding analyses of environmental peatland samples for Oribatida in Germany as well as in Central Europe. |

Attention Score in Context
This research output has an Altmetric Attention Score of 1. This is our high-level measure of the quality and quantity of online attention that it has received. This Attention Score, as well as the ranking and number of research outputs shown below, was calculated when the research output was last mentioned on 14 August 2017.
All research outputs
#18,572,005
of 23,849,058 outputs
Outputs from Experimental and Applied Acarology
#552
of 914 outputs
Outputs of similar age
#223,678
of 311,778 outputs
Outputs of similar age from Experimental and Applied Acarology
#5
of 17 outputs
Altmetric has tracked 23,849,058 research outputs across all sources so far. This one is in the 19th percentile – i.e., 19% of other outputs scored the same or lower than it.
So far Altmetric has tracked 914 research outputs from this source. They receive a mean Attention Score of 3.8. This one is in the 30th percentile – i.e., 30% of its peers scored the same or lower than it.
Older research outputs will score higher simply because they've had more time to accumulate mentions. To account for age we can compare this Altmetric Attention Score to the 311,778 tracked outputs that were published within six weeks on either side of this one in any source. This one is in the 23rd percentile – i.e., 23% of its contemporaries scored the same or lower than it.
We're also able to compare this research output to 17 others from the same source and published within six weeks on either side of this one. This one has gotten more attention than average, scoring higher than 64% of its contemporaries.
