An unidentified harvestman Leiobunum sp. alarmingly invading Europe (Arachnida: Opiliones)
2007
Etwa seit dem Jahr 2000 breitet sich eine bisher nicht identifizierte Art der Gattung Leiobunum C. L. Koch, 1839 schnell in Mitteleuropa aus. Nachweise ab dem Jahr 2004 sind aus den Niederlanden (wahrscheinlich dem Land des ersten Auftretens in Europa), Deutschland, Österreich und der Schweiz bekannt. Die wahrscheinlich eingeschleppte Art besiedelt bisher lediglich Wände von Gebäuden und seltener felsähnliche Biotope in Wäldern. Adulte Individuen ruhen tagsüber selten einzeln oder in eng geklumpten Gruppen aus Dutzenden bis Hunderten von Individuen an leicht abgedunkelten Stellen in Mauerwinkeln, an glatten Hauswänden und überhängenden Dachtraufen. Jungtiere leben am Boden. Diese Art verfüg…
Characterization of microbial communities in pest colonized books by molecular biology tools
2011
This work presents the identification of bacteria and fungi colonies in insect infesting books, by cultural-independent methodologies based on molecular biology techniques. Microbial genomic DNA extraction,<em> in vitro</em> amplification of specific target sequences by polymerase chain reactions (PCR), sequencing and sequence analysis were performed. These procedures minimized the samples amount, optimized the diagnostic studies on bacteria and fungi colonization and allowed the identification of many species also in complex microbial consortia. The molecular techniques for sure accomplish and integrate the microbiological standard methods (<em>in vitro</em>&nbs…
Bacteria, fungi and arthropod pests collected on modern human mummies
2011
A survey of opportunistic biocenosis (macro and micro organisms) associated with a rest of human mummy samples was carried out to characterise the biocenosis and to detect the potential of biodeteriogens. The rests of the human modern mummies come from a hypogeic site. Since mummies are relevant from a historic-artistic-scientific point of view, an aspect of this study was the identification and characterization of the biological systems related with biodeterioration of organic matter. In a first step, different sampling methods, according to the taxa, were applied. Technological procedures were combined in order to have an interdisciplinary approach to the conservation actions for testing …
New molecular data attest to the absence of cospeciation patterns between Placobdella costata (Fr. Müller, 1846) (Hirudinea) and freshwater turtles (…
2021
The only Palearctic representative of the leech genus Placobdella Blanchard, 1893 is P. costata, an ectoparasite of freshwater turtles. To date, no conclusive evidence about the possible presence of coevolutionary patterns between this leech and its turtle hosts is available due to the paucity of DNA sequence data available for P. costata; moreover, comparative host data is also mostly lacking, making any inferences more difficult. The discovery of new populations of the species in northern Italy and Sicily allowed us to generate novel mitochondrial DNA sequences and to compare the topology of the resulting phylogenetic trees with the phylogeny of the turtle hosts occurring in the study are…
Crossing a Multi-Lane Street: Irrelevant Cars Increase Unsafe Behavior
2011
Before crossing a road or an intersection, road users have to determine among the surrounding traffic whether or not they have enough time to safely complete their maneuver. Temporal judgments have been investigated for single cars approaching an intersection, however, close to nothing is known about how street-crossing decisions are being made when several vehicles are simultaneously approaching in two adjacent lanes. We conducted a simulator experiment in which observers indicated whether or not they had enough time to complete safe street crossing. Traffic gaps were presented either with a single or two oncoming cars on different lanes, in such a way that in all cases, only the shortest …
Comparative analysis and antimicrobial action of some essential oils from plants
2021
In this research, essential oils (EOs) were extracted through steaming from aerial parts of three plants: basil (Ocinum basilicum L.), peppermint (Mentha piperita L.) and oregano (Origanum vulgare L.) form Sibiu County, Romania. The GC-MS analysis indicated that eugenol and apiol were the major compounds in the basil EO. Timol, ɣ-terpinene, and p-cymene were the major compounds in the volatile oil extracted from oregano and menthol and methone the main components in the peppermint EO. In the first 48 h of analysis, basil EO inhibition action was the highest against Salmonella anatum (48%), followed by Aspergillus niger (26%), Bacillus cereus (21%) and Saccharomyces cerevisiae (15%); this ac…
Histoire et évolution des appellations d'origine françaises
2019
During the 20th century, wine appellations of origin have largely developed to represent a significant part of the wine production of some countries, especially in Europe. The globalization of the production, trade and consumption of wine is a major fact of the 21st century economy. The question of appellations of origin and more generally geographical indications must be asked: Is it a survival 100 years after the first law on appellations of origin was adopted in France? Historical knowledge makes it possible to understand how law, both national and international, has been marked by major developments in this area. Regulations on the origin of products have undergone significant changes o…
L'histoire du vin comme patrimoine et atout économique
2017
La connaissance historique du vin est aujourd'hui un enjeu scientifique, culturel mais aussi economique. La precocite du commerce international et de la consommation du vin dans de nombreuses regions du monde permet d'avoir une reflexion en longue duree – sur plusieurs siecles – concernant la globalisation. Au 20e siecle l'instauration de normes internationales partagees, notamment grâce a l'activite de l'OIV, donne aujourd'hui encore a reflechir sur un developpement economique international appuye sur des normes partagees. Le traitement numerique et la mise a disposition du Bulletin de l'OIV fondes sur un travail universitaire realise a Dijon est un outil mis a la disposition de tous pour …

2 Section of Hydrobiont Diseases, Pacifi c Research. Fisheries Center, Shevchenko str., 4, Vladivostok, 690950 Russia Taxonomic Status of Neoechinorhynchus agilis (Acanthocephala, Neoechinorhynchidae), with a De- scription of Two New Species of the Genus from the Atlantic and Pacifi c Mullets (Teleostei, Mugili- dae). Tkach, Ie. V., Sarabeev, V. L., Shvetsova, L. S. — Th e wide variability in morphological features, geographical and host ranges of mullet acanthocephalan parasite Neoechinorhynchus agilis (Rudolphi, 1819), raises the question of taxonomic status of this species. Rudolphi's type and Yamagutis voucher specimens, as well as our own material from the WW Pacifi c and NE Atlantic r…
