Creating e-learning course on biodiversity in the European project Key to Nature
type: item
description: An e-learning course in biodiversity was conducted for the first time among universities in Bulgaria in Shumen University. The aim was to use the opportunities provided by the project Key to Nature (sponsored by the EC Programme eContentPlus) and the e-learning platform Moodle to develop and support the delivery of specialised training courses in Higher Education. In order to realise this goal the authors have developed a sample course in Botany. The course was conducted in the period September 2010 - February 2011. Thirty six students studying biology participated in the course. The results show that it provides an accessible option for remote collection, publication and verification of information of different nature and sources. The course proved the effectiveness of e-learning as a form of self-study that complements traditional forms. In the future, we expect an increase of the role of e-learning in Bulgarian universities, and even to replace some (parts) of the conventional study forms.

Review of the medicinal plants of the North Black Sea Coast (Bulgaria)
type: item
description: This is the first review of the studies of medicinal plants found in the region of North Black Sea Coast. It shows the significant diversity of the medicinal plants in the northern part of Black Sea Coast floristic region: 593 species of vascular plants from 357 genera and 96 families. The majority of the families and genera are represented by a small number of species, which ranges from 1 to 4. The analysis of life forms indicates that the hemicryptophytes dominante (43.17%). The biological types are represented mainly by perennial herbaceous plants (54.81%). The highest percentage of species belongs to the European type (55.48%), followed by species of the Mediterranean type (17.54%). Among the medicinal plants one Balkan endemic, one Bulgarian endemic and 32 relicts are found. The number of species with conservation status is 55 (9.27%). 18 species are protected by a law prohibiting the herb colection within their natural habitats and collecting of 9 species is restricted by the law regulating the collection of herbs from their natural habitats. The number of antropophytes is relatively high 374 (63.07%). References: Assyov B., Dimitrov D., Vassilev R. & Petrova A. 2002.

Review of the current status and future perspectives on Pseudogymnoascus destructans studies with reference to the species findings in Bulgaria
type: item
description: Emerging infectious diseases are a well-known threat to the wildlife and require complex research. There is a rapidly accumulating knowledge on the infectious disease of bats (White Nose Syndrome - WNS/White Nose Disease - WND) and its causative agent - the pathogenic fungus Pseudogymnoascus destructans. Although mass mortality of bats, known since a decade, is currently restricted to North America, the pathogen is of global concern as a potential threat to other hibernating bat populations. Therefore five years after the first comprehensive synthesis on the fungal ecology and relevant knowledge gaps (Foley et al. 2011), we decided to summarize the published information on the pathogen morphology, reproduction, ecological requirements, geographic distribution and systematic position. In addition, the present review compiles the available data on the affected bat species, mechanisms of WND, on the host response and on the effective treatment strategies with possible methods forfighting the pathogen to reduce the mortality in affected regions as well. Special attention is paid to the finding of the fungus in Bulgarian caves. References: Amelon S. & Knudsen G. 2010.

Phytoplankton of the reservoir “Dospat” (Rodopi Mts, Bulgaria) as indicator of negative trend in reservoir development due to long-term cage fish farming
type: item
description: The paper presents the results of the recent (2011) investigation of phytoplankton composition and abundance, with its seasonal and spatial dynamics in the reservoir “Dospat” (the first in Bulgaria used for cage fish farming) and shows the changes in its waters after 30 years of exploitation. Totally 55 taxa from 7 divisions have been identified: Cyanoprokaryota (8), Pyrrhophyta (3), Euglenophyta (4), Cryptophyta (1). Ochrophyta (Bacillariophyceae - 26; Synurophyceae - 2), Chlorophyta (9) and Streptophyta (2), Cyanoprokaryotes have been recorded for first time in the reservoir and their harmful species Planktothrix rubescens and Aphanziomenon flos-aquae were found among the dominants and subdominants. The highest number of species was detected in June (42), the phytoplankton communities near to the dam were more species-rich and with higher abundance in comparison with those in the tailwaters, most probably due to the effect of the fish cages situated in the uppermost part of the reservoir. According to the average phytoplankton biomass (1,39 mg l-1) in 2011 the reservoir “Dospat” could be classified as mesotrophic. However, it has to be noted that this value is twofold higher in comparison with 1972-1975 period, when the biomass was 0.7 mg l-1. Most probably, the changes in the species composition, the increase in the phytoplankton biomass and of the reservoir trophic status are related with the effects from the cage fish farming.

Diatom diversity of springs and spring-fed streams in Vitosha Nature Park, Bulgaria
type: item
description: The paper presents the first contemporary study of the diatom diversity of the springs, spring-fed streams, peat bogs and mires forming the headwaters of three rivers (Bistrishka River, Boyanska River and Strouma River) in Vitosha Nature Park. Diatom samples were collected from all natural substrata at each sampling site - epilithon, epiphyton and epipelon. A total of 353 taxa (298 species, 53 varieties and 2 forms) belonging to 70 genera were found. The highest number of species was observed in the genera Navicula s.l., Achnanthes s.l., Pinnularia, Gomphonema and Eunotia. Fifty-nine taxa are new to the Bulgarian algal flora, and 305 taxa are reported for first time for Vitosha Mountain. The dominant structure of the diatom communities was identified and the number of rare and threatened species was assessed. One hundred and seven taxa (30% of all taxa found in the study) are included in the Red List of limnic diatoms of Central Europe. Notes on some interesting taxa are provided.

The first record of marasmius limosus and pholiota conissans (basidiomycota) in Bulgaria
type: item
description: The paper provides information on the first finding of Marasmius limosus Quél. and Pholiota conissans (Fr.) M. M. Moser in Bulgaria. Both fungi were found as saprotrophs on decaying leaves and stems of Typha angustifolia L. in the karstic swamp Dragomansko Blato. Morphological data obtained by light microscopy are provided for both species. The easy recording of both species in the swamp in the middle of October allows the suggestion for further autumn searching for macromycetes in wetlands. References: Barsakoff B. 1929.

Aerophytic green algae, epimycotic on Fomes fomentarius (L. ex Fr.) Kickx.
type: item
description: Four species of green algae were found on the upper surface of Fomes fomentarius (L. ex Fr.) Kickx. basidiome. Desmococcus vulgaris (represented by both vegetative cells and aplanosporangia) dominated among them. Trebouxia arboricola (represented by free living vegetative cells and autosporangia), and two species of Stichococcus (S. bacillaris, S. minutus) were the other identified algae. It is proposed to use the term “epimycotic” (from the greek “epi”- over and “mykes” - fungus) for algae and/or other organisms capable of growing and developing on the upper surface of fungal fruiting bodies.

The effect of the Eminium regelii extract on cellular immunity
type: item
description: The article presents the results of a study on the effects of the wild medicinal plant Eminium regeln Vved. extract to the body of intact and subjected to emotional stress animals on the background of a long-term low dose of gamma-radiation. The reaction of the animal organism to the effects of radiation, emotional stress and the introduction of the E. regeln extract were evaluated by the total content of leukocytes, absolute and relative content of lymphocytes (including CD3+, CD4+, CD8+), immunoregulatory index (IRI) and leukocyte migration inhibition reaction (LMIR). The experiments were performed on adult mongrel white rats of both sexes. At the early stage of the general adaptation syndrome (GAS) the injection of E. regeln extract caused a decrease in the total number of lymphocytes, an increase in the number ofCD4+ lymphocytes and leukocytes lymphokinproduction abilities. Late stage of GAS was indicated by increased CD3+ and CD4+ lymphocytes, and increased values of the immunoregulatory index. References: Artemova A. G. 1973.

A new method for assessment of the red lIst threat status of microalgae
type: item
description: Although the IUCN Red List Categories and Criteria is a widely internationally used system for classifying species at high risk of extinction, the micro-organisms are still practically excluded from the appropriately enlisted taxa. The present paper provides a method, which gives means to assess microalgae threat status much more objectively than it was possible before and in this way to achieve quite high degree of generalization in work with this peculiar group of organisms. The method described below uses the widely accepted standard IUCN Red List system of categories, but proposes their assignment on the basis of a complex application of seven criteria relevant to microalgae and classical data, available for them. These criteria can be interpreted in the same way for all taxonomic groups of algae and for all possible territorial levels (local, national, regional, global). The criteria are denominated with Latin capital letters A-G and each of them has a numerical expression with values (points) ranging between 4 and 1. The final assessment of the threat status is done on the basis of the total amount of points (T), which ranges between 7 and 28. In this way each alga is supplied with a formula (a combination of letters and numbers), which indicates its threat status and in the same time outlines its most critical, “weak spots” on which special attention has to be paid when conservation measureshave to be proposed. As it is exemplified in detail in the paper, the formula could be expressed in a table or in a text format, in full or in a short version, depending on the needs of the relevant studies or proposals (e.g. Anabaena lapponica Borge [VU - A3 B4 C4 D2 E2 F2 G3], or Anabaena lapponica Borge [VU - A3 B4 C4 D2 E2 F2 G3 T20], or Anabaena lapponica Borge [VU - T20]), or Anabaena lapponica Borge [VU]).

Antioxidant potential of Bulgarian yarrow and thyme
type: item
description: Phenols (sometimes called phenolics) are synthesized by plants for their general defense and particularly in response to antioxidative stress. These biologically active compounds are well known to have beneficial effects on human health. The aim of the present study was to apply a fast in vitro approach to compare the antioxidant potential of yarrow (Achillea millefolium L.) and thyme (Thymus vulgaris L.) that were freshly collected from their natural habitat in the Rodopi Mts with some randomly selected herbs for infusion from traders in Sofia region. Ethanol extracts from yarrow and thyme plants were compared with an extract from the Chinese white tea {Camellia sinensis (L.) Kuntze) used for infusion and known for its high phenolic content with antioxidant effect. The total quantity of phenols in both studied herbs varied in a close range but was 5-8 times lower than this in the white tea. The average antioxidant activity in thyme was slightly higher than in yarrow but was nearly four times lower in comparison to their activity in the white tea. Slight variations between the herbs from the Rodopi Mts and Sofia were found in the phenolic content of yarrow and thyme, and in the antioxidant activity of thyme. Significant positive correlation between the content of phenolic and antioxidant activity was observed in white tea and thyme, but not in yarrow but our in vitro approach would need to be confirmed by further in vivo analyses. Our results show that the genotype, habitat and storage conditions could influence the plant antioxidant potential and that it is likely that the Bulgarian herbs contain additional classes of metabolites which determine distinct biological activities.

Phytoplankton interactions as main focus of the 18th workshop of the International Association of Phytoplankton Taxonomy and Ecology (IAP)
type: item
description: This paper aims to summarize the work, topics and contributions of the 18th Workshop of the International Association of Phytoplankton Taxonomy and Ecology (IAP), which took place in Natal, Rio Grande do Norte - Brazil, from August 27 to September 3, 2017. The Organizing committee was chaired by professors from two Brazilian universities at Natal and Sao Carlos and comprised scientists from Brazil and Argentina. In total, 39 scientific reports (5 plenary lectures, 20 oral presentations and 13 posters), prepared by 152 contributors from 20 countries were presented. The phytoplankton interactions were the main focus of the workshop, introduced in five plenary lectures. Most other presentations also dealt with this topic: they considered interactions among phytoplankters and phytoplankton-zooplankton interactions, but there was also an interest for processes involving mixotrophic organisms, phytoplankton-bacteria interactions, phytoplankton macrophytes interactions, parasitism and trophic webs. The factors influencing the phytoplankton development and diversity in different environments, as a background for phytoplankton interactions and drivers of phytoplankton diversity, were also discussed. Different aspects of the phytoplankton diversity were also presented with special emphasis on biodiversity conservation. Traditionally, methodological support for microscopic plankton counts and size measurements and trait-based approaches were among the side-topics of the workshop. Several future lines of research were suggested on the basis of the meeting summary. References: Abonyi A., Descy J.-P., Lwcon A. M., Leitao M. & Minaudo C. 2017.

type: item
description: This study aims to supplement the available research data on medicinal plants for the territory of Shabla-Ezeretz Lake Complex Protected Area by carrying out a taxonomic and analysis of the Holistic elements and creating a database of their therapeutic action, usable parts and the groups of diseases they are applicable for. The medicinal plants identified as such in our surveys constitute 113 species of higher plants referring to 46 families and 91 genera. The predominant biological types are herbaceous perennial plants - 69 species or 61 percent. With respect to moisture and humidity as a factor dominant position hold the mesophytes - 49 species (43%). Eurasian geo-elements are prevalent (26 species or 23%), followed by Euro-Mediterranean, cosmopolitans and sub-Mediterranean (14 species or 12%). Among the medicinal plants in the studied wetlands there are 33 species (29%) of conservation significance. The established medicinal plants have a wide variety of more than 3 8 types of healing action. Half of them are used mainly for the treatment of gastrointestinal diseases, kidney and urinary tract diseases, respiratory diseases, and those with haemostatic action. The species in which the above ground part (herba) is collected dominate over the rest and represent half of the established for the area medicinal plants. References: Asenov I. & Nikolov S. 1988.

Checklist of algae from Bulgarian thermal waters
type: item
description: The paper provides annotated Checklist of Bulgarian thermal algae mentioned in the publications on thermo-mineral springs, baths and their effluents and updated according to the last taxonomic considerations. The list contains data on 35 thermal systems and totally 206 taxa from five algal divisions (phyla): Cyanoprokaryota (82), Rhodophyta (4), Ochrophyta (44:3 - Tribophyceae, 40 - Bacillariophyceae), Chlorophyta (32) and Streptophyta (44). Among them 21 species are of conservation importance according to the Red Lists of Bulgarian macroalgae and microalgae, and of the Red Data Book of R Bulgaria as well. According to their threatened status they are spread in the following groups: Critically Endangered (1), Endangered (4), Vulnerable (6), Near Threatened (5) and Data Deficient. (5). On the background of the increased pace of habitat losses due to capturing of the springs, construction of new modem SPA centers with permanent cleaning of the algae, or usage of springs for heating purposes or as laundries, this Checklist can serve as a basic archive for future investigations of this important ecological group of extremophilic algae.

Impact of demographic characteristics of the local population of the Northern Black Sea coast on the use of medicinal plants
type: item
description: The present study aims to examine the impact of demographic indicators gender, age, education and place of residence on the use of medicinal plants by the native population of the Northern Black Sea coast. The survey was conducted in eleven cities and nine villages between April and June 2015. The face-to-face interview technique was used and the respondents were randomly selected. The impact of demographic indicators on the respondents’ answers was assessed by calculating the correlation coefficient of Pearson (r). The results show that the majority of respondents (83.78%) used medicinal plants mainly for treatment and prevention of diseases, approximately half of them (45.95%) used them for nutrition. Respondents using medicinal plants for decoration and for business have an insignificant share (9.73% and 1.08%, respectively). From the demographic analysis of the results, a moderate influence of all four demographic indicators on the respondents’ answers was registered. The analysis of cross-links revealed that the attitude to the use of medicinal plants by women, unlike men, was not significantly influenced by age. The share of respondents from rural areas using medicinal plants for treatment and prevention of diseases was equal to those using them for nutrition, while the respondents from the cities using medicinal plants for treatment and prevention were twice more than those using them for nutrition. Regional differences were discovered comparing our data for use of medicinal plants of the local population with published data from the inland of the country.

Cyanoprokatyote and algal biodiversity in the tropical Lake Edward (Africa) with notes on new, rare and potentially harmful species
type: item
description: The paper presents data on the biodiversity of prokaryotic and eukaryotic algae in the tropical Lake Edward, compiled from publications of the Damas mission (1935 -1936 ), Hecky & Kling (1987) and our own results from a recent investigation of the lake phytoplankton in a three-year period (2016-2018) in the frame of the HIPE (HumanJmjiacts on ecosystem health and resources of Lake Edward) project (http://www.co2.ulg.ac.be/hipe). The provided checklist is based on modem algal taxonomy with relevant synonymizing of lists of previous authors. In total, 577 taxa from seven divisions were registered in the lake waters and in the Kazinga Channel. The richest division was Ochrophyta (287 taxa, 274 of which from Bacillariophyceae), followed by Chlorophyta (131 taxa), Cyanoprokaryota (134), Streptophyta (14), Euglenophyta (8), Pyrrhophyta (5) and Cryptophyta (1). 52 species (or only 1% of the taxa found) persisted in the lake since 30s of the 20th century till nowadays. More than half of the cyanoprokaryotes (65) are potentially toxic and harmful species. The checklist contains also data on algal abundance and frequency of occurrence, originally provided by the authors. In the phytoplankton samples, collected during the three cruises of the HIPE project, 248 taxa were found, among which the richest division was Cyanoprokaryota (104). From this total of 248 taxa, only 3 were frequent and 199 were very rare (from 1-3 samples) with 121 taxa found in one sample only. During 2016-2018, the most abundant species in the lake phytoplankton belonged to Cyanoprokaryota, Bacillariophyceae and Chlorophyta. The algae found in the lake have different ecological requirements and besides clear tropical species and some cosmopolites, some “cold water species” from northern and temperate regions were found. For them, as well as for some thermophilic species, considered alien for the lake, transport through different vectors was supposed. In the literature analyzed, 36 new taxa were described.…

Aethionema arabicum Andrz. ex DC (Cruciferae) in Bulgaria - in situ and ex situ conservation
type: item
description: Aethionema arabicum Andrz. ex DC is extremely rare species of the Bulgarian flora. It is included in the Biological Diversity Act of Bulgaria and in the Red Book of Bulgaria with category Critically Endangered. The species is distributed in Balkan Peninsula (Bulgaria and Turkey), Southwest Asia (Asia Minor, Syria, Northern Iran) and the Caucasus. The only population of A. arabicum known in Bulgaria is situated in Eastern Stara planina floristic region, near Sotirya village, Sliven district. The population consists of only a few dozen individuals. This study provides information on the biology and ecology of the species, its population structure and the measures taken to increase the population. Protected area was designated to preserve this species. References: Barrett S. C. H. 2002. The evolution of plant sexual diversity. - Nature Genetics 3: 274-284. Chater A. O. 1964. Aethionema R.
