Continental data on cave-dwelling spider communities across Europe (Arachnida: Araneae)
Background
Spiders (Arachnida: Araneae) are widespread in subterranean ecosystems worldwide and represent an important component of subterranean trophic webs. Yet, global-scale diversity patterns of subterranean spiders are still mostly unknown. In the frame of the CAWEB project, a European joint network of cave arachnologists, we collected data on cave dwelling spider communities across Europe in order to explore their continental diversity patterns. Two main datasets were compiled: one listing all subterranean spider species recorded in numerous subterranean localities across Europe and another with high resolution data about the subterranean habitat in which they were collected. From these two datasets, we further generated a third dataset with individual geo-referenced occurrence records for all these species.
New information
Data from 475 geo-referenced subterranean localities (caves, mines and other artificial subterranean sites, interstitial habitats) are herein made available. For each subterranean locality, information about the composition of the spider community is provided, along with local geomorphological and habitat features. Altogether, these communities account for > 300 unique taxonomic entities and 2,091 unique geo-referenced occurrence records, that are made available via the Global Biodiversity Information Facility (GBIF) (Mammola and Cardoso 2019). This dataset is unique in that it covers both a large geographic extent (from 35 south to 67 degrees north) and contains high-resolution local data on geomorphological and habitat features. Given that this kind of high-resolution data are rarely associated with broad-scale datasets used in macroecology, this dataset has high potential for helping researchers in tackling a range of biogeographical and macroecological questions, not necessarily uniquely related to arachnology or subterranean biology
Javorella suvodolensis, a new endogean species of ground beetles (Trechini, Carabidae, Coleoptera) from southwest Serbia
PRODUCT DEVELOPMENT USING QUALITY FUNCTION DEPLOYMENT (QFD)
The company subsistence on the open market is heavily dependent on its capacity to identify new customer requirements and to develop a new product. The Quality Function Deployment (QFD) is method which can be used in new product development process ?1?. In research which results are presented here, QFD method was applied for creating soap quality improvement plan. Analysis is based on customer's evaluation about importance of some characteristics for product quality

The adults of three ground-beetle species were induced to discharge defensive secretions into vials. The secretions were obtained by CH2C12 extraction. Altogether 11 compounds were identified by GC-MS analysis. Calosoma sycophanta possesses 10 defensive compounds, Carabus ullrichii seven, while Abax parallelepipedus has six compounds. Methacrylic, tiglic and isobutyric acids were present in all samples. The first two organic compounds were predominant in the extracts of Abax parallelepipedus. Methacrylic acid and salicylaldehyde were the major compounds in extracts of Calosoma sycophanta. Methacrylic and angelic acids were the major components in extracts of Carabus ullrichii. Propanoic acid was detected for the first time in the family Carabidae and in all animals. 2-Methyl butyric, angelic and benzoic acids were found for the first time in the subfamily Carabinae. Our finding of butyric acid is its first precise identification in the Carabinae subfamily. 2-Methyl butyric, angelic, crotonic, senecioic and benzoic acids were found for the first time in a European groundbeetle species. The compounds detected in the defensive secretions serve as protection against predators
