The toxicity of nonylphenol (NP) to springtails was pronounced at 40 mg/kg dry weight soil, at which no animals survived. Body length and fecundity were the individual life-history traits significantly stimulated by sublethal concentrations of NP during a 64-day experiment. However, the effects of NP on these traits did not result in a statistically significant increase in population growth rat...

Remarks: Neat Na-LAS was 16.1 % (w/w) active C11.6 LAS in an aqueous solution, average molecular weight = 342 g/mol; Ca-LAS was > 99 % active C11.6 LAS (crystalline), average molecular weight = 674 g/mol (Ca is bivalent and therefore, each Ca atom has 2 LAS molecules); Mg-LAS 94 % active C11.6 LAS (crystalline), average molecular weight = 658 g/mol (Mg is bivalent and therefore, each Mg atom ha...

Abrasion of tire wear is one the largest sources microplastics to environment. Although most particles settle into soils, studies on their ecotoxicological impacts terrestrial environment are scarce. Here, effects (<180 μm) three ecologically relevant soil invertebrate species, enchytraeid worm Enchytraeus crypticus, springtail Folsomia candida and woodlouse Porcellio scaber, were studied. Thes...

Synthetic fibers released from sewage sludge and tire particles traffic are among the most common types of microplastics in soil. In soil, may interact with chemicals, such as plant protection products used agriculture. Most studies on interactions chemicals focused aquatic environments only few addressed soil arthropods. To increase understanding combined effects arthropods, we studied polyest...

Recently, an active set of beta-lactam biosynthesis genes was reported in the genome of the arthropod springtail Folsomia candida (Collembola). Evidence was provided that these genes were acquired through horizontal gene transfer. However, successful integration of fungal- or bacterial-derived beta-lactam biosynthesis into the metabolism of an animal requires the beta-lactam precursor L-α-amino...

Drought tolerance (survival at 98.2% relative humidity and 20 degress C) was investigated for adult individuals of the springtail Folsomia fimetaria after three weeks of exposure to different polycyclic aromatic compounds (PACs). Seven PACs were investigated (acridine, dibenzofuran, carbazole, fluorene, dibenzothiophene, fluoranthene, and pyrene), with each substance used at several exposure co...

The material for this study was obtained after intensive sampling in the colluvial mesovoid shallow substratum, or MSS, of Sierra de Guadarrama National Park using 33 subterranean devices (SSD). data were from first extraction traps between May and October 2015. This paper presents results Entomobryomorpha Börner, 1913, which part Collembola captured. Four families 12 genera have been studied: ...
