Sympatry of genetic lineages of s. l. (Collembola, Isotomidae) in the East European Plain.

(Schaeffer, 1896) is one of the most abundant eurytopic species of springtails in temperate regions of the northern hemisphere, and is often used as a model species for studies on the genetics of soil microarthropod populations. Six genetic lineages (L0, L1, L2, L3, L4-Saltzwedel, L4-Hebert) are known which are distributed mainly parapatrically in Western and Central Europe. Individuals of from 21 locations on the East European Plain were analyzed.

[Reasons for lethal outcomes in severe multiple trauma].

The article is based on an analysis of causes and terms of lethal outcomes of 490 patients after a severe combined trauma. Lethal outcome in 16.9% of the patients took place within an hour after admission to clinic.
