This study aimed at relating the abundance and diversity of invertebrate communities of urban soils to chemical and physical soil characteristics and to identify the taxa most sensitive or tolerant to soil stressors. The invertebrate community of five urban soils in Naples, Italy, was sampled. To assess soil quality invertebrate community indices (Shannon, Simpson, Menhinick and Pielou indices)...
We aimed to describe the main Arctic biogeographical patterns of the Collembola, and analyze historical factors and current climatic regimes determining Arctic collembolan species distribution. Furthermore, we aimed to identify possible dispersal routes, colonization sources and glacial refugia for Arctic collembola. We implemented a Gaussian Mixture Clustering method on species distribution ra...
A comparative analysis of the taxonomic and ecological structure meadow-steppe collembolan taxocenes Eastern Podillya was carried out. 77 species Сollembola belonging to 41 genera 14 families were found on studied territory. From 6 18 collembola at level point alpha diversity, 40–42 coenotic which indicates a large capacity soil environment for in this type biocenoses Podillya. The investigated...
Although their functional importance in ecosystems is increasingly recognized, soil-dwelling micro-arthropods are usually poorly known in comparison with their above-ground counterparts. Collembola constitute a significant and species-rich component of the soil biodiversity, but it remains a woefully understudied group because of the taxonomic impediment. The ever-increasing use of molecular ta...
Climate warming can destabilize interactions between competitors as smaller organisms gain advantages in warmer environments. Whether and how warming-induced effects on competitive interactions are modified by predation remains unknown. We hypothesized that predation will offset the competitive advantage of smaller prey species in warmer environments because of their greater vulnerability to pr...
the present faunal study of springtails (collembola) was conducted -in city of tehran during 2013-2014. samples of soil and leaf litters from parks, forests, gardens and green landscapes were collected using berlese funnels. a total of 21 species of eight families were identified of which the species hypogastrura ripperi (gisin, 1952), mesaphorura macrochaeta (rusek, 1976) and friesea claviset...
خانواده ایزوتومیده (isotomidae) دومین خانواده بزرگ از لحاظ تنوع گونه ای در راسته پادمان (collembola) می باشد. این شش پایان بدن کشیده و بدون فلس دارند و بر خلاف خانواده انتموبریده (entomobyridae) طول همه بندهای شکمی یک اندازه می باشند. اکثرگونه های این خانواده در اکوسیستم های خشکی، و در خاک یا بقایای گیاهی زندگی می کنند ولی عده ای از گونه ها را می توان از روی آب در اکوسیستم های آبی پی...
Soil properties and the growth maturation of herbaceous plants are known to be influenced by soil fauna (Collembola) temperature. But little is about how these two factors interact. We hypothesised that vegetative reproductive responses Poa annua L. presence Collembola density will change according P. was grown in microcosms with or without at different air temperature conditions, 16 °C as a Lo...
