The article presents the changes in physical dimensions of Poecilus cupreus under the influence of various ecological factors. The field data comprising 7 habitats of 4 regions (Tatarstan, Ukraine, Chechen Republic, Kostroma region) was gathered. The morphometric study comprised 6 measuring criteria while body size is one of the most significant morphological characters linked with the ontogenesis length, motion activity, reproductive rate, competition capacity. Poecilus cupreus' sizes are stipulated by horizontal zonality and altitudinal zonation. Size alteration is caused by the period of resource availability, i.e. the length of growing season. A shorter season in higher latitudes and high-mountain restricts the period appropriate for feeding, growth and development, and, consequently, for the maximum body size. The body size and form are determined by a set of factors. The most important factors are, apparently, the bugs' wintering area, microclimatic habitat conditions and food availability. The discriminative analysis has revealed that the population composition of P. Cupreus statistically differs in all regions. The most alike are the populations of Chechen Republic and Kostroma region, which is due to the certain similarity of altitudinal and latitudinal belts. Presumably, the length of the vegetation period in highmountain is identical to the one in northern latitude. Reportedly, the most different from all are the bugs from Tatarstan. The ground beetles agrocenoses are characterized by a significant difference in the width of the elytra and pronotum. It can be due to the living environment when certain body proportions help to find the appropriate habitats in certain agricultural plants.

Влияние рекреации на сообщества почвенной мезофауны лесопарковой зоны г. Ка-зани. -Гордиенко Т. А., Вавилов Д. Н., Суходольская Р. А. -Для оценки состояния ле-сопарковой зоны г. Казани изучали население почвообитающих беспозвоночных в трех массивах широколиственных лесов с разной степенью рекреации. Численность мезофауны в лесопарках значительно выше по сравнению с пригородным лесом. Таксономический со-став сообществ педобионтов в ряду смежных лет существенно не меняется, доминируют дождевые черви. Однако их численность подвержена сильным колебаниям по годам. Значи-тельные изменения испытывает трофическая структура мезофауны в биотопе с наибольшей антропогенной нагрузкой, что показали результаты дискриминантного анализа и анализа главных компонент. Перестройки в структуре сообществ педобионтов, когда в разные годы основную нагрузку несут разные трофические группы, можно считать элементами адапта-ции мезофауны в лесопарках к антропогенному влиянию.Ключевые слова: почвенная мезофауна, дождевые черви, трофические группы, лесопар-ковая зона, пригородная зона, многолетняя динамика численности, многомерная статистика.Recreation impact on soil macrofauna communities in the forest-park zone of Kazan city. -Gordienko T. A., Vavilov D. N., and Sukhodolskaya R. A. -To evaluate the status of the forest-park zone of Kazan City, the soil invertebrate populations in three deciduous forest plots with various recreational degrees were studied. The macrofauna abundance in forest-parks was significantly higher in comparison with suburb forests. The taxonomic composition of the pedobiont communities did not change significantly within the period studied, with earthworms predominated. However, their abundance varied strongly from year to year. The trophic structure of the mesofauna in the biotope under the highest anthropogenic load is subject to significant changes, shown by PCA and discriminant analysis. The reorganizations in the pedobiont community structure, when different trophic groups carry the major load in different years, can be considered as elements of the mesofauna adaptation to the anthropogenic impact in forest-parks.

Intra-specific body size variation in ground beetles is studied insufficiently, especially in response to climatic factors. Even less studied is the sexual dimorphism (hereinafter referred to as the SSD), its geographic variation patterns and response to climatic factors. We sampled ground beetles Pterostichus melanarius in 15 regions of Northern Eurasia along latitude and longitude gradients (in 17 degrees and 121 degrees, respectively), including differing habitats (open and forested) in the spectrum of anthropogenic impact (cities, suburbs, arable lands and natural). 7677 specimens were measured by six morphometric traits – elytra, pronotum, head length and width, distance between eyes. Our software applied made it possible both to catch the smallest changes in the size of traits in females and males, and to determine their direction. Temperature related factors mostly reduced beetles traits values, but precipitation related factors – enlarged them. Elytra and pronotum parameters were the traits which response differently in males and females to climatic factors, these traits showed more pronounced SSD. Head parameters showed SSD in response to those factors too. That response had the similar direction and was expressed more, either in females or males. The latter processes implemented to a greater extent in relation to the temperature including bioclimatic factors.

Приведены результаты анализа высотной изменчивости морфометрической структуры выборок Carabus odoratus barguzinicus (Shil., 1996). Особенности морфометрической структуры, наряду с различиями исходных размеров мерных признаков, позволяют предположить, что между низко-и высокогорной популяциями не существует постоянного генетического обмена.
