Selective neuronal staining in tardigrades and onychophorans provides insights into the evolution of segmental ganglia in panarthropods
The organisation of the nervous system in three tardigrade species using antisera directed against tyrosinated and acetylated tubulin, the amine transmitter serotonin, and the invertebrate neuropeptides FMRFamide, allatostatin and perisulfakinin shows correspondences that support the homology of segmental ganglia in tardsigrades and arthropods.
Active dispersal of oribatid mites into young soils
Active dispersal is an important dispersal mechanism in the colonization of young soils, however, several species combine different dispersal mechanisms, so that the number of possible dispersal pathways is one factor that determines specimen- and species-richness in a newly found habitat.
Tardigrade species composition in young soils and some aspects on life history of Macrobiotus richtersi J. Murray, 1911
In an afforested coal-mining site at Berzdorf, Germany, the soil tardigrade community was investigated and life history investigations on a strain of parthenogenetic Macrobiotus richtersi demonstrated a significant influence of temperature on egg development, survival rate, body growth and generation time.
Soil nematode fauna of afforested mine sites: genera distribution, trophic structure and functional guilds
It was demonstrated that food web development at Berzdorf followed distinct shifts in soil primary succession, and no continuous increase in the complexity of food web interactions from younger successional stages to older stages was revealed.
Soil nematode abundance and functional group composition at a global scale
High-resolution spatial maps of the global abundance of soil nematodes and the composition of functional groups show that soil nematode are found in higher abundances in sub-Arctic regions, than in temperate or tropical regions.
How to tackle the molecular species inventory for an industrialized nation-lessons from the first phase of the German Barcode of Life initiative GBOL (2012-2015).
The GBOL project, a consortium of natural history collections, botanic gardens, and universities working on a barcode reference database for Germany's fauna and flora, finds that validating taxon lists to serve as a taxonomic backbone is time-consuming but without alternative.
First detailed observations on tardigrade mating behaviour and some aspects of the life history of Isohypsibius dastychi Pilato, Bertolani & Binda 1982 (Tardigrada, Isohypsibiidae)
New insights into the mating behaviour of a bisexual tardigrade, Isohypsibius dastychi, are provided, revealing a process much more complex than expected.
Predicting and testing functional responses: An example from a tardigrade–nematode system
The parameterized satiation model seems to include the most important determinants of the functional response in the focal system, and more studies that compare data to independently derived model predictions are needed for understanding functional responses.
Development o of s soil f fauna a at m mine s sites d during 46 y years a after a afforestation
Summary At the afforested overburden heap „Langteichhalde“ (lignite mining district Berzdorf, Eastern Germany) a long-term study of the soil fauna (since 1961) was completed by new investigations
Primary colonisation of newly formed soils by actinedid mites
The microarthropod communities continued to be strongly dominated by actinedid mites and colonisation of the soils remained spatially heterogeneous, and the abundances and species richness increased significantly three years after site initiation, although they were still low compared to mature soils.
