The structure and seasonal dynamics of myriapods (Chilopoda and Diplopoda) in the southern taiga of the Perm Cis-Urals Region

The spatial and temporal dynamics of myriapod assemblages in the Preduralye protected area (Kishertskii District, Perm Territory) is studied. There are 10 species found, which have been assigned to three landscape groups (floodplain, terrace, and forest species) and four phenological groups (spring-summer, summer, latesummerautumn, and autumn species). Seasonally stable differences are found between myriapod assemblages of riverine biotopes (floodplain and fluvial terraces) and those of drainage divides (hillsides and uplands). The structure of the myriapod assemblage changes thrice in the course of the growing season. The spring-early-summer pattern develops without drastic transformations into the summer one, which is characterized by maximum diversity. The establishment of the autumn pattern is marked ubiquitously by stronger dominance of two eurybiont species, a lithobiomorph centipede Lithobius curtipes (C.L. Koch, 1847) and a millipede Altajosoma golovatchi (Shear, 1990), which is accompanied by the simplification of the species structure and the reduction of diversity of taxocenes. The horizons of the application of the landscape-phenological classification of species are briefly discussed, as well as the consideration of phenological patterns during invertebrate surveys.
