Abstract
We sampled beetles by pitfall traps at two sites of its area: Visimskiy Reserve ((580N 610E, Kirovgrad province, Russia, the western border of area) and Kemerovo city (540N 810E, Kemerovo province, Russia, the centre of area). At the first site birch and meadows plots were under study, at the second ‒ meadows and lawns in the residential and industrial zones and the dump in 25 km from the city. 2109 specimen were measured for six linear traits. Elytra parameters were similar at both regions studied, but another traits (pronotum and head) were significantly larger in the beetles from Reserve. Populations morphometric structure differed significantly at all sites studied. Factors “Province”, “Anthropogen”, “Biotope” and “Sex” affected beetles body size and structure of its populations. We conclude, that populations at the edge of the area can reproduce and survive successfully due to the mechanism that had been revealed earlier: either body size or the structure of the population change.
Highlights
Organism body size is a fundamental trait in ecology [1,2,3]
Body size is correlated with ecological processes across multiple scales, including individual fecundity [4], population biology [5,6], disease transmission [7], food web structuring [8,9] and ecosystem services [10,11]
In relation to climate change different efforts need in study of body size and morphometric structure variation as the phases of ground beetles adaptation to the heterogeneous environment
Summary
Organism body size is a fundamental trait in ecology [1,2,3]. Understanding variation in body size informs both fundamental and applied ecological research. Based on this assumption, there are numerous studies from multiples disciplines that involve body size as the key aspect of evolutionary adaptation and diversification of organisms [e.g., 12-14]. There are numerous studies from multiples disciplines that involve body size as the key aspect of evolutionary adaptation and diversification of organisms [e.g., 12-14] In this context, variation in body size represents one of the crucial raw materials for evolution to occur. While certain details might remain unknown, simple metrics should provide insight on most prominent traits
