Abstract

Two new benzobisimidazole platforms incorporating 7-hydroxyquinoline moieties were synthesized and characterized to explore potential multiple proton transfer processes. Combining experimental analysis with theoretical insights, we investigated the photophysical properties and excited-state proton transfer phenomena within these systems and found that double proton transfer is unlikely to happen.

30. Quantitative Morphometric Analysis of Morphologically Similar Species of Fragilaria (Fragilariaceae, Bacillariophyta) Allows Detection of Non-Indigenous Taxa: A Case Study from Lake Ladoga (North of European Russia).

Abstract

In Lake Ladoga (northwestern Russia), we found a diatom, putatively Fragilaria sublanceolata-baikali, an endemic species from Lake Baikal (southeastern Siberia, Russia). To determine whether this population matches a previously recognized species from Lake Baikal and assess how it differs from other similar Fragilaria taxa, we studied the valve morphology of three morphologically similar Fragilaria populations (the putative F. sublanceolata-baikali, F. pectinalis and F. perminuta) sampled in Lake Ladoga, along with a population of F. sublanceolata-baikali sampled in Lake Baikal. We used light and scanning electron microscopy with a combination of traditional and geometric morphometric methods. To analyze covariation between the valve shape and size (i.e., allometry), we examined differences in the ontogenetic–allometric trajectories at both the interspecific and intraspecific levels. In addition, the effect of size correction of the valve shape on species differentiation was tested. Traditional morphometrics revealed that F. sublanceolata-baikali is distinguished from F. pectinalis and F. perminuta by valve length, while F. pectinalis and F. perminuta are distinguished by striae density. All three species of Fragilaria showed separate and parallel allometric trajectories. In contrast, the two populations of F. sublanceolata-baikali were on a common allometric trajectory, indicating the conspecificity between these populations. Prior to allometric correction, geometric morphometrics was not able fully discriminate between the three Fragilaria species. After allometric correction, the three Fragilaria species were clearly separated in a size-corrected morphospace, whereas the two populations of F. sublanceolata-baikali formed a tightly overlapping group. Thus, we conclude that geometric morphometrics can reliably distinguish between these morphologically similar species of Fragilaria, but only after accounting for allometric shape variation. Our study confirmed morphological similarity between the two geographically distant populations of F. sublanceolata-baikali, which indicates that this taxon can be considered as invasive in Lake Ladoga.

Abstract

A survey was conducted of 240 Bulgarian citizens from the Danube region, the Republic of Bulgaria, to study their awareness and readiness for protection and proper behavior in floods. The participants in the study were divided into two age groups: young from 18 to 39 years and mature from 40 to 64 years. The respondents live in two municipalities from the Danube region - a small municipality of Svishtov and a larger municipality of Pleven. Assessment of the awareness and readiness for proper behavior and protection of the studied group of 240 persons permanently living in the Danube region: - A small percentage of the two surveyed groups know who organizes and provides assistance to flood victims - 47% of the young and 38% of the mature group. - The percentage of sirens for early warning of danger is small in both groups of bags - 47% from a young group and 30% from an adult group. - The two age groups showed in the survey that they are well informed about the main causes of past dangerous floods in the municipalities where they live (65% correct answer in the adult group and 44% correct answer in the young group). - Below 50% in both groups is the level of awareness about problems related to deforestation, excessive deforestation and long-lasting forest fires. - Half of 50% of both age groups know in advance where to look for information related to floods or other natural threats. - There is a large percentage in both groups, 66% mature and 81% young group, who expressed in the survey a desire to increase their own knowledge and to improve and build the right behavior for protection in case of potential flood or another disaster.

Abstract

A survey of 240 Bulgarian citizens from the Danube region, the Republic of Bulgaria, was conducted to examine their awareness and readiness for protection and proper behavior in floods. The participants in the study were divided into two age groups: young people aged 18 to 39 years and mature from 40 to 64 years. The percentage of respondents who have experienced a flood in the past is high (24%). The two analyzed groups are well informed about the risks and disasters causing epidemics (34% young group and 45% adult group). The groups are well informed about the potential threat of floods in the settlement (45% young group and 25% mature group). We give high marks to the two studied groups for the fact that they have preliminary insurance of the home, property, have a backpack prepared for evacuation, know how to swim and maintain their systematic skills (84%). All this will help in a real situation to save their lives.
