Type material of three Nipponentomon species, N. andrei, aureitarsum and californicum, are analysed. Additional descriptions include morphological characters, which were not described earlier, such as chaetotaxy head, length shape setae on nota foretarsus, porotaxy tergites sternites. The updated key for all known 16 species is provided.

Ectomycorrhizal fungi (ECM) play a central role in nutrient cycling boreal and temperate forests, but their the soil food web remains little understood. One of groups assumed to live as specialised mycorrhizal feeders are Protura, experimental field evidence is lacking. We used combination three methods test if Protura specialized compared trophic niche with other invertebrates. Using pulse labelling young beech ash seedlings we analysed incorporation 13C 15N into Acerentomon gallicum. In...

Background Protura is a group of tiny, primarily wingless hexapods living in soil habitats. Presently about 800 valid species are known. Diagnostic characters very inconspicuous and difficult to recognize. Therefore taxonomic work constitutes an extraordinary challenge which requires special skills experience. Aim the present pilot project was examine if DNA barcoding can be useful additional approach for delimiting determining proturan species. Methodology Principal Findings The study...

The head porotaxy and chaetotaxy was studied in three families of proturans the order Acerentomata: Hesperentomidae,Protentomidae Acerentomidae. Protentomidae is highly diversified. A system setae names developed applied for a phyletic analysis Acerentomata.

Abstract Based on recent reexamination of types, Vesiculentomon rusekiNosek, 1977, differs significantly from marshalliRusek, 1974, in composition and shape maxillary gland, number anterior setae metanotum, foretarsal sensillum t1. A new genus Nosekientomon is erected for V. ruseki. n. gen. characterized by three pairs the claviform t1, a smooth globular vesicle calyx gland. Rusek has four baculiform large near with dense granulation along its narrow proximal part. The original descriptions...

Disturbances are intrinsic drivers of structure and function in ecosystems, hence predicting their effects forest ecosystems is essential for conservation and/or management practices. Yet, knowledge regarding belowground impacts disturbance events still remains little understood can greatly vary by taxonomic functional identity, type local environmental conditions. To address this gap knowledge, we conducted a survey soil-dwelling Protura, across forests subjected to different regimes (i.e....
