Pinus nigra Arn. associations prevail. The xerophilic and thermophilic species, such as Carpinus orientalis Mill., Quercus pubescens Willd. and Quercus cerris L. are dominants and edificators in the deciduous associations. The slopes with northern component offer favourable conditions for the development of associations, whose dominant are mesophilic species ( Tilia tomentosa Moench.) on one hand, and the participaton of ephemeras ( Dasypyrum villosum (L.) Cand.), in grass associations on the other.

The study is based entirely on literary sources, thematically divided into four areas: botany and phytogeography, world and European heraldry; national symbols and emblems and the Web of Science and Research Gate information platforms. The study establishes the vectors of spread of plant species as a symbolic elements in the countries of Europe as a result of cultural, commercial, religious and scientific connections. Moreover, the continuity of the abiotic factors of the environment (terrestrial biomes) allows plant species to cross the borders of Europe and pass into Asia. The discovered similarities, continuity and duplication of a number of plant-based symbolic elements in countries of both continents are proof of a common past, a shared culture and are an ideal basis for achieving understanding between peoples speaking different languages and professing different religions.

The notions of the high reproductive capabilities of the species have been refuted, even with provided resources, shelter and human attention. Space and density are not major stressors in a multi-cat indoor group if a high-protein food and inner freedom of individuals are provided. The established natural patterns in its development and the parallel made between other wild felines and human population are evidence of the evolutionary value and genetic potential of the species, which must be assessed and preserved in time. Specific adaptive behavior in female individuals related to indoor life and possibly a way of self-control of reproduction is described

Plant diversity is categorized with respect to biological type, phyto-geographic belonging, and Nature preserving status. Common objective laws, connected with distribution of the flora and plant life in our country are found.

A logical consequence of climate drought and the increased human activity today are the fires around settlements. On burned areas plant communities are formed with a specific composition and structure. This study aims to analyze the floristic composition on three of the after- fire communities, occurring at different times in the Stara Zagora green zone. An analysis of Raunkiaer life forms is made and the degree of canopy cover is calculated on Braun Blanquet. The results allow to predict the development of secondary plant succession on burned areas.

Significant floristic diversity is registered on an area of 40 hectares - 125 species of higher plants (mosses excluded), belonging to 97 genera and 41 families. Investigation is conducted in the 2006 ÷ 2008 time span. Taxonomic structure, ecological and biological type, and floristic belonging of the components of the flora are analyzed. 5 Balkan endemics and 4 species with Nature preservation status according to Bulgarian and International legislation are found.

This fact increases the significance of every investigation, connected with floristic composition and biologic diversity in anthropogenically loaded territories. But in the cities and suburban areas a positive correlation is often reported between the degree of urbanization of the environment and species diversity, due to the wealth of man-made habitats. The current study analyses the conservation significance of the Eastern Sredna Gora Mountain floristic subregion. The low altitude and favorable geographical location make the region extremely overloaded from anthropogenic point of view. Despite this, 30 species with Nature conservation status, according to the Bulgarian and international legislation are registered as a result of the examination, 3 species are confirmed for the Sredna Gor...

Tel.: +359 42 699319 e-mail: syl_rad@yahoo.com ABSTRACT Synanthropization of flora and vegetation is a global phenomenon, revealed quite distinctively in big cities floras. Significant parts of ligneous and frutescent species, which form urban floras originate from remote floristic regions and are characterized with long-term acclimatization and naturalization, while these periods are by far shorter when grass species are concerned. This study analyzes the condition of 27 seed plants of North American origin with different residential status. Comparative analysis comprises abiotic specification of their natural areas, dendrologic features, artificial breeding, metric data achieved for Bulgaria, and condition of representative exhibits of the same taxa in the city. Conclusions are drawn with respect to the degree of adaptatio...

Трансферът им е проследен на фона на развитието на обществените формации в Европа и на Балканите. Специално внимание се отделя на вярата и мястото, което тя заема в съзнанието на човека - от първобитния до съвременния. Откриването на типично български символи в други народи доказва континиума в обществените отношения, осъществяван чрез търговия, религия, наука, образование.

Their transfer is analyzed against the background of the development of social formations in Europe and the Balkans over the centuries. Special attention is paid to faith and the place it occupies in the consciousness of man - from primitive to the modern. The discovery of typically Bulgarian symbols in other nations proves the continuum in social relations, realized through trade, religion, science, education.
