With respect to current distribution of dragonflies the Lublin region (south-eastern Poland) belongs to one of the best studied areas of the country. However, the larger studies that have been published so far are mainly related to peripheral areas of this ground and the state of knowledge on its central part is still incomplete. The author presents data on dragonflies of one of the most naturally valuable areas of this ground – Kozłowieckie Forests protecting the biggest forest complex of the vicinities of Lublin city. The studies were conducted in the years 1999–2006 (mainly 2004–2006) at 35 study sites. 45 dragonfly species were found. The fauna of Kozłowieckie Forests is typical of forest areas under moderate anthropopression (meliorations, regulations, water pollutions, fish pond management in river valleys). The activity of a human being had double impact on the fauna: either negative or positive. From one hand tyrphobionts have disappeared, the number of some tyrphophiles and rheophiles has decreased or vanished. Lacustrine species and odonatocenoses have appeared as well as the conditions for the development of thermophilous refugial species like Lestes barbarus, Erythromma viridulum, Aeshna affinis, Anax imperator, Orthetrum albistylum, Sympetrum depressiusculum, S. fonscolombii. Kozłowieckie Forsests are not the area of great importance for dragonfly protection. They can be treated as the refugium of species diversity for the central part of the Lublin region, however, they do not play the important role in protection of threatened species or odonatocenoses.
Between 12 and 23 July 2006, dragonflies of selected localities in the Vasyugan Plain, West Siberia, were studied by Rafał Bernard and Oleg Kosterin. The article presents personal impressions of the first author from this expedition, partly based on the odonatological results. Our investiga- tions were focused on the largest in the world complex of Sphagnum bogs and fens, and on rivers flowing between them. Additionally, smali anthropogenic water bodies were also visited. In total, 34 odonate species were recorded. An important result of our expedition is the picture of the summer aspect of the odonate fauna in these mostly primeval and remote boggy areas, with the flourish- ing complex of peat-moss bog species and an interesting species composition in rivers. Nehalennia speciosa (the main aim of our expedition) and Aeshna subarctica, both species poorly known and considered to be rare in Siberia, appeared to be omnipresent
The Tatra Mountains constitute an area of great natural value. They comprise all bioclimatic zones typical for true alpine environment and play an important role for conservation of European biodiversity. For almost two centuries, the Tatra nature has been attracting interest of scientists of many specializations. Although history of investigations on beetles dates back to the middle of the XIX century, only one monographical work, concerning Curculionoidea, has been published so far. Other coleopteran groups have been only partially studied, and recent data are scarce. In this paper, we give an overview of current data on the fauna of Coleoptera in the Polish part of the Tatra Mts. Summarizing data from the Catalogue of the Fauna of Poland (KFP) and results of our own studies, we estimate beetle richness of the Polish part of the Tatras at 1415 species representing 81 families. We also try to answer questions on accuracy and representativeness of data in KFP, and propose solutions to improve knowledge of this group in the future.
