Populationsbiologische Untersuchungen zur Art Entomobrya nivalis (Collembola)

Theoretische und experimentelle Untersuchungen zur Protonierung

The structural parameters and energies of the protonated compounds c/o5o-[B6H5HtacF]and c/o5o-[B6H5HtacCH3]_ are calculated by MP2/6-31G* optimization, as have the ’H, "B , 13C and i9F NMR shifts using a tzp basis set and the RHF/GIAO method. The results for the octahedral molecule anions confirm the preferred localization of the additional proton in [B6H5HtacX]~ in case of X = CH3 at the upper...

Taxonomic review and phylogenetic analysis of fifteen North American Entomobrya (Collembola, Entomobryidae), including four new species

The chaetotaxy of 15 species of eastern North American Entomobrya is redescribed in order to determine potential characters for the diagnosis of cryptic lineages and evaluate the diagnostic and phylogenetic utility of chaetotaxy. As a result, four new species (Entomobrya citrensis Katz & Soto-Adames, sp. n., Entomobrya jubata Katz & Soto-Adames, sp. n., Entomobrya neotenica Katz & Soto-Adames, ...

Redescription of Entomobrya quinquelineata Börner , 1901 ( Collembola : Entomobryidae ) and description of three new species

A study of all available specimens of E. quinquelineata Börner, 1901 from different museums and private collections, revealed that more than one species was involved. We reached this conclusion by using conventional taxonomical characters and patterns of macrochaetotaxy. We redescribe here the specimens most probably identical to Börner's original material, and describe three new species, one f...
