A new locality of Telescopus fallax (Reptilia: Colubridae) in Bulgaria
(Plovdiv University "Paisii Hilendarski", 2026-09-25) Gochev, Vladimir; Naumov, Borislav
A new locality of the European Cat Snake, Telescopus fallax, is reported in Bulgaria: the village of Malko Gradishte, Lyubimets Municipality. This locality is situated relatively close to the already known ones, but orographically belongs to the Maritsa River Valley, an area for which the species was previously unknown. An updated distribution map of T. fallax in Bulgaria is also presented.
New records of non-marine snails at Sainte-Anne, Martinique
(Plovdiv University "Paisii Hilendarski", 2026-09-21) Georgiev, Dilian; Mishev, Todor
The paper presents new data on the distribution of non-marine molluscs from the vicinities of Sainte-Anne, Martinique (Lesser Antilles). Field surveys conducted in August 2026 recorded a total of 16 species. Among them, several records expand the known distribution of terrestrial snails on the island, including the second locality record of the introduced Huttonella bicolor (T. Hutton, 1834) on Martinique.
Cyto- and genotoxic effects of Actellic 50 EC and Rival pesticides on cells of Allium cepa L.
(Plovdiv University "Paisii Hilendarski", 2026-06-22) Stoyanov, Ivan; Vasileva, Penka; Staykova, Teodora; Popova, Teodora; Ivanova, Evgeniya
Pesticides are widely used synthetic compounds that can persist in the environment and pose significant risks to non-target organisms. Given their potential to induce genetic damage, their genotoxicity can be assessed through mutagenicity testing with suitable model systems. In the present study, the general toxic, cytotoxic, and mutagenic effects of two widely used pesticides, Actellic 50 EC (active substance pirimiphos-methyl) and Rival (active substance propamocarb hydrochloride), were evaluated using Allium cepa L. as a test model. Both formu-lations are used in agricultural practice to control insect pests, storage pests in cereals, and soilborne pathogens. The results demonstrated that Actellic 50 EC (at concentrations of 10 μg/L and 60 μg/L) and Rival (at concentrations of 40 μg/L and 80 μg/L) exerted a clear cytotoxic effect, as evidenced by a reduction in the mitotic index. Their genotoxic potential was confirmed by the induction of a wide spectrum of chromosomal aberrations, including anaphase and telophase bridges, chromosomal fragments, lagging and vagrant chromosomes. In addition, a significant increase in micronuclei frequency was observed, further supporting the genotoxic effects of the tested pesticides. Further studies using additional biological models and molecular genetic approaches are needed to better elucidate the mechanisms underlying the toxic action of these pesticides.
Environmental risks from thermal power plants that use coal as raw material for a long time – a case study from Kosovo
(Plovdiv University Press "Paisii Hilendarski", 2026-09-11) Musliu, Adem; Shabani, Milazim; Baftiu, Naim
Air and water pollution, along with heavy metal contamination, constitute some of the most pressing environmental issues affecting Kosovo. In recent years, the overall environmental situation in the region has deteriorated due to increased construction, traffic, and industrial pollution. This includes emissions from power plants and household heating during winter. Integrating sustainability into strategic energy planning is imperative for security policies and is well within the reach of emerging economies like Kosovo. The outdated technology and lack of effective regulations for air emissions from the two thermal power plants - Kosova A and Kosova B - have led to significantly higher stack emissions compared to coal plants in Western Europe. The specific impacts on vulnerable populations, such as children, the elderly, and those living close to the Obiliq power plants, have not been adequately studied. The construction of the new coal power plant - Kosovo C, represents a step forward in the energy sector but raises concerns about carbon dioxide emissions as a greenhouse gas pollutant. Currently, most energy production in Kosovo relies heavily on water usage across various power plants. Efforts are being made to reduce the environmental impact of Kosova A and Kosova B by decreasing dust, sulfur dioxide (SO2), and nitrogen oxides (NOx) emissions. It is crucial to shift towards producing green energy through sources like solar, water, and wind power to significantly mitigate these environmental challenges.
Amulets and Apocryphal Prayers in Bulgarian Literature and Culture
(Plovdiv University Press, 2025) Adinolfi, Roberto
Apocrypha have been a part of Bulgarian literature since its earliest stages and include apocryphal prayers, which are often contained in amulets. There are prayers against several kinds of illnesses, misfortunes, evil beings, and, generally against threats to human prosperity and well-being. Following a tradition from ancient times, in these prayers and incantations we can find large narrative parts, which at times bear similarities to folk tales. This is the case of the prayers of St. Sisinnius. Several of the apocryphal prayers are found in texts from different epochs; for instance, one should think of the letter of King Abgar to Jesus, excerpts of which can already be found in lead amulets from the 10th century, but it is also part of the first Bulgarian printed books. Today’s folk rituals share similarities with Medieval prayers. This paper focuses on the analysis of some apocryphal motifs through the centuries.
