This study aimed at clarifying the species composition and ecological structure of carabids, associated with active pastures. Field work was carried out in 2017 and 2018. Pitfall traps (5 in each site) were set in 10 sampling sites in Thracean Lowland and Sarnena Sredna Gora Mts. Captured beetles belonged to 90 species and 33 genera, representing 12% of the species and 26% of the ground beetle genera occurring in Bulgaria. The most diverse was genus Harpalus (22 species), followed by the genera Amara (7 species), Microlestes (6 species), Ophonus (6 species) and Parophonus (5 species). Twenty species were new for the region of the Thracean Lowland: Amara fulvipes (Audinet-Serville, 1821), Anisodactylus binotatus (Fabricius, 1787), A. intermedius Dejean, 1829, Apotomus clypeonitens Müller, 1943, Calathus cinctus Motschulsky, 1850, Carterus gilvipes (Piochard de la Brûlerie, 1873), Gynandromorphus etruscus (Quensel en Schönherr, 1806), Harpalus fuscicornis Ménétriés, 1832, H. subcylindricus Dejean, 1829, Microlestes apterus Holdhaus, 1904, M. corticalis (L. Dufour, 1820), M. fulvibasis (Reitter, 1901), M. maurus (Sturm, 1827), M. minutulus (Goeze, 1777), Notiophilus laticollis Chaudoir, 1850, Pangus scaritides (Sturm, 1818), Parophonus laeviceps (Ménétriés, 1832), P. planicollis (Dejean, 1829), Polystichus connexus (Geoffroy in Fourcroy, 1785) and Pterostichus strenuus (Panzer, 1796). Twenty species were new for the whole Sredna Gora Mts.: Acinopus picipes (Olivier, 1795), A. megacephalus (P. Rossi, 1794), Amara anthobia A. Villa et G. B. Villa, 1833, Ditomus calydonius (P. Rossi, 1790), Harpalus albanicus Reitter, 1900, H. angulatus Putzeys, 1878, H. attenuatus Stephens, 1828, H. dimidiatus (P. Rossi, 1790), H. flavicornis Dejean, 1829, H. pumilus Sturm, 1818, H. pygmaeus Dejean, 1829, H. subcylindricus Dejean, 1829, H. tardus (Panzer, 1796), H. signaticornis (Duftschmid, 1812), Lebia scapularis (Geoffroy, 1785), Microlestes fissuralis (Reitter, 1901), M. fulvibasis (Reitter, 1901), M. maurus (Sturm, 1827), M. minutulus (Goeze, 1777) and Ophonus sabulicola (Panzer, 1796). Fourty-one species were new for the region of the Sarnena Sredna Gora. Genus Apotomus, Gynandromorphus, Pangus and Polystichus were new geographic records for Thracean Lowland. Genera Acinopus and Ditomus were new for the Sredna Gora Mts. Fourteen life form categories were established (9 zoophagous and 5 mixophytophagous). The analysis of the life forms showed a slight predominance of the mixophytophages (53 species; 59%) over the zoophages (37 species; 41%). Microlestes minutulus was a constant species occurring in all sampling sites.

In the conditions of Western Transbaikalia, Chlaenius tristis reticulatus Motschulsky, 1844 has a one-year late spring – early summer life cycle with the hibernation of a young generation of beetles. The interpretation of their life cycle is based on the study of sex and age-related structure of imago, the seasonal activity of generative females, the above-ground activity of larvae, and stages of the development of beetles in the laboratory conditions. The changes in the seasonal activity of beetles on meadows with different soil moisture (steppificated, moistened, and marshy meadows) were identified.

AbstractPlanting non-native tree species, like Douglas fir in temperate European forest systems, is encouraged to mitigate effects of climate change. However, Douglas fir monocultures often revealed negative effects on forest biota, while effects of mixtures with native tree species on forest ecosystems are less well understood. We investigated effects of three tree species (Douglas fir, Norway spruce, native European beech), on ground beetles in temperate forests of Germany. Beetles were sampled in monocultures of each tree species and broadleaf-conifer mixtures with pitfall traps, and environmental variables were assessed around each trap. We used linear mixed models in a two-step procedure to disentangle effects of environment and tree species identity on ground beetle abundance, species richness, functional diversity and species assemblage structure. Contradictory to our expectations, ground beetle abundance and functional diversity was highest in pure Douglas fir stands, while tree mixtures showed intermediate values between pure coniferous and pure beech stands. The main drivers of these patterns were only partially dependent on tree species identity, which highlights the importance of structural features in forest stands. However, our study revealed distinct shifts in assemblage structure between pure beech and pure Douglas fir stands, which were only partially eased through mixture planting. Our findings suggest that effects of planting non-native trees on associated biodiversity can be actively modified by promoting beneficial forest structures. Nevertheless, integrating non-native tree species, even in mixtures with native trees, will invariably alter assemblage structures of associated biota, which can compromise conservation efforts targeted at typical species composition.

Abstract The results of our own investigations as well as the literary data about ground beetle fauna of Gomel’ city are summarized in the article. The assessment of species composition and a wide range of carabidocomplexes ecological parameters have been examined. 131 ground beetles species have been detected for urbancenosis of Gomel’ city (41 per cent of species registered on the territory of the Republic of Belarus). In general, ground beetles of Gomel’ city are presented quite well in the Palearctic and their communitites are basically composed of field, meadow, and forest mesophilous and mesoxerophilous species but small in size populations in urbancenosis.

AbstractMost studies on riverine ground beetle assemblages last 1–2 years, and studies on carabids from lowland stream ecosystems are rare. In 1999, a 16-year study was launched to gain insight into the structure and diversity of carabid assemblages in a cross-section of four habitats located beside a 5 m wide stream: Meadow (wet meadow), Clumps (meadow scattered with birch and willow clumps farther from the river), Birch (birch stand), and Pine (pine stand located the farthest from the stream). The total number of 14, 216 individuals representing 118 carabid species were collected. Eleven functional carabid groups have been analysed. Principal response curve analysis showed significant differences existing during the whole study period among carabid assemblages from the four habitats. Generalised Linear Mixed Models analysis revealed a dependence of Chao2 estimator performance on temperature and ground water level, whereas life traits of carabids depended solely on the latter factor, affecting species composition (i.e., proportions of autumn and spring breeders, large and small zoophages, hemizoophages, forest, generalists and open area species, wingless species, hygrophilous, mesophilous and xerophilous species). The lower the ground water level, the higher was the proportion of late-successional species. Both Chao2 value and the proportion of late-successional species were growing with the increasing distance from the stream, peaking in the Pine habitat. Early-successional fauna dominated in streamside assemblages. IndVal analysis identified 1–9 characteristic species for each habitat type, mostly non-recurrent during the study period. Thus, species composition of riverine carabid assemblages should be studied for longer periods than 1–2 years to avoid accidental observations.

Уточнено видовий склад комах-фітофагів агробіоценозу пшениці озимої в Правобережному Лісостепу України. За результатами моніторингу ентомокомплексу пшениці виявлено 55 видів шкідливих комах з 19 родин, які в тій чи іншій мірі можуть пошкоджувати цю культуру. Ряд жуки, або твердокрилі (Cоleoptera), характеризувався найбільшим видовим різноманіттям. За результатами проведених досліджень з’ясовано, що основними і найбільш небезпечними фітофагами, які завдають значної шкоди в Правобережному Лісостепу є комплекс комах-шкідників колосся: злакові попелиці, хлібні клопи, хлібні жуки, пшеничний трипс, хлібний турун. We clarified the species composition of insects-phytophagous of winter wheat agrobiocenosis in the Right-Bank of Forest-Steppe of Ukraine. According to the results of monitoring of wheat entomocomplex we found 55 species of harmful insects from 19 families that in one way or another can damage the crop. The order Coleoptera was characterized by the highest species diversity. The results of the study found that the main and most dangerous pests that cause significant damage in the Right-Bank of Forest-Steppe is a complex of pests ears: aphids, wheat bugs, wheat chafers, thrips, cereal ground beetle.
