The “Źródła Rzeki Łyny im. prof. R. Kobendzy” nature reserve was established in 1959 and occupies the area of 120.54 ha. The paper describes fl ora and plant communities of this reserve. In total 409 vascular plant taxa from 70 families and 235 genera were inventoried, including 24 species which are under legal protection, as well as rare plants and those which are threatened in this region. Nine plant communities were identifi ed within the boundaries of the reserve of which three were forest autogenic or autogenic-like communities (Ribeso nigri-Alnetum, Stellario nemorum-Alnetum glutinosae, Tilio cordatae- -Carpinetum betuli), three were forest anthropogenic communities with Pinus sylvestris, Betula pendula, Larix decidua and Larix ×eurolepis and Picea abies on lime-oak-hornbeam forest sites, as well as three non-forest communities (Salicetum pentandro-cinereae, Phragmitetum australis and a meadow community from the Molinio-Arrhenatheretea class). The highest natural value was determined in very well developed phytocoenoses of Stellario nemorum-Alnetum glutinosae (the rarest in the reserve), in Ribeso nigri-Alnetum and Tilio cordatae-Carpinetum betuli, as well as meadow communities from the Molinio-Arrhenatheretea class. They provide sanctuary for many species of rare and threatened plants.

A survey of the capacity to endure desiccation was obtained for several Brazilian rock outcrop plants. Seedlings, leaves and entire plants were subjected to dehydration. After dehydration, survival was observed as the ability to recover growth, chlorophyll content and/or by the absence of leakage of leaft contents. A total of 30 species growing in rock outcroppings in southeastern Brazil showed some ability to undergo extreme dehydration. The species belong to the cryptogams Polypodiaceae, Pteridaceae, Schizaeaceae and Selaginellaceae and to the angiosperms Cyperaceae, Poaceae and Velloziaceae. All cryptogams were homeochlorophyllous. Among the angiosperms Microchloa indica (Poaceae) was the only species with the capacity to retain chlorophyll content during dehydration. All species showed some evidence of desiccation tolerance similar to that previously reported for tolerant angiosperms in Africa. The data suggest that rock outcroppings from the southeastern and central regions of Brazil give support to typical vegetation in which a great number of species exhibit a desiccation-tolerant comportment.

The old forest complex of Rzepiszew (76.81 ha of land) is located in the east part of Szadek commune. It is surrounded by arable fields and meadows. At present it is a timber forest, but forest management is based on ecological rules. 260 Vascular plant species forming 55 families have been found in this area during field research which was carried out in years 2006-2010. The identified species represent different types of growth (= life forms in Raunkiaer's terminology) Hemicryp- tophytes have been found to dominate. The flora contains plants from various ecological groups classed according to light conditions, moisture of soil, soil acidity and soil trophy. Most of them are stenotopic plants - they have a limited (narrow) ecological amplitude. The true forest species are the most valuable components of flora. Seven among them are protected by law.

A list of vascular plants in the planned reserve “Gorajskie Parzyska” is presented in this paper. 226 taxa out of 152 genera and 57 families of vascular plants were inventoried. The most representative families are: Fabaceae, Asteraceae, Poaceae, Rosaceae, as well as Salicaceae, Caryophyllaceae, Cyperaceae, Lamiaceae, Apiaceae, Ranunculaceae and Scrophulariaceae. There were 19 species catalogued as species of special care as they are under total or partial legal protection and are listed on the Polish National Red List and on Regional Red List for Wielkopolska. The study area (9.26 ha) seems to be particularly valuable in comparison to the rest of Czarnkowska Moraine to other stands where endangered or protected species were found.
PL
Na terenie projektowanego rezerwatu „Gorajskie Parzyska” zinwentaryzowano 226 taksonów roślin naczyniowych ze 152 rodzajów i 57 rodzin. Najliczniej reprezentowane są rodziny Fabaceae, Asteraceae, Poaceae, Rosaceae oraz Salicaceae, Caryophyllaceae, Cyperaceae, Lamiaceae, Apiaceae, Ranunculaceae i Scrophulariaceae. Wyróżniono 19 gatunków „specjalnej troski”, zarówno będących pod ochroną całkowitą bądź częściową, jak i znajdujących się na krajowej lub regionalnej (dla Wielkopolski) „czerwonej liście” gatunków zagrożonych. Pod względem liczby gatunków na tak małej powierzchni (9,26 ha), w porównaniu z całym terenem Moreny Czarnkowskiej, oraz stanowisk gatunków rzadkich i chronionych, obszar ten wydaje się szczególnie cenny.

In contrast to other natural objects situated within boundaries of the city of Poznań, the former ecological site "Bogdanka" distinguishes itself by its exceptional floristic values. The flora of this object comprises 527 taxons of vascular plants derived from 91 families and 295 genera, of which 180 can be found on rare and threatened species lists. In addition, 15 species under legal protection as well as 34 species from all country and regional lists of rare and endangered species occur here. The most valuable floristic elements include: Iris sibirica, Galium odoratum, Hierohloë odorata, Trollius europaeus or Dianthus superbus. Several trees with monumental or close to monumental circumferences as well as splendid trees can also be found in this site. The area should regain its protected status as soon as possible.

The vascular flora in the “Łąki w Komborni” Natura 2000 site comprises 219 species representing 44 families and 147 genera. Species from the families Asteraceae, Poaceae, Lamiaceae, Fabaceae, Rosaceae, Polygonaceae, Cyperaceae, Apiaceae, and Ranunculaceae were found to dominate. A geographical and historical analysis of species confirmed the clear dominance of apophytes (84%) over anthropophytes (16%) as well as perennials (69%) over short-lived (23%) species. The biological spectrum was dominated by hemicryptophytes (54%) and therophytes (19%), compared with other life forms. In terms of synecology, the flora was mainly represented by species from the classes Molinio-Arrhenatheretea, Stellarietea mediae, Artemisietea vulgaris and Phragmitetea. The “Łąki w Komborni” site is a habitat for 82 (37%) medicinal species and 155 (70%) forage species for bees. Noteworthy is the occurrence of protected species, e.g. Gladiolus imbricatus, Trollius europaeus, Centhaurium erythraea, Dactylorhiza majalis, Platanthera bifolia and Primula elatior.

The aim of the study was to compare the feeding activity of soil fauna in seven temperate forests with the application of the bait-lamina method. Seven types of temperate forests located throughout Poland (East-Central Europe) were tested, ranging from dry pine forest with a typical poor quality soil to eutrophic riparian fresh deciduous forest. Each forest type was represented by five stands and all stands altogether represented natural gradient of soil fertility, texture and vegetation diversity. Despite clear diversification between the studied forest types according to a range of soil physicochemical properties and vegetation characteristics in addition to applying recommended measurement conditions for the method, we determined that the feeding activity of soil fauna did not differ between forest types. The activity of soil fauna did not depend on site botanical characteristics or any soil physical or chemical features, indicating that the bait lamina method was useless in measuring the feeding activity of soil fauna in temperate forest soils. Differences in the feeding activity of soil fauna might result from other environmental factors that influence soil fauna feeding activity in forest stands that were not measured here, i.e., soil temperature and humidity. The differences could also be attributable to the attractiveness of the bait substrate to soil fauna, which may be different in various soil conditions.

“Uroczysko Wielkie Łunawy” belongs to objects which can be distinguished for their considerable floristic values. Varied and slightly deformed flora of this small object comprises 192 species of vascular plants derived from 60 families, including 41 taxons of arborescent plants. Sites of 13 species under legal protection were identified. Valuable fragments of oak-hornbeam and riparian forest communities as well as stands close to natural ones were also found. It seems that, bearing in mind the relatively rare and wellpreserved communities of the oak-hornbeam and riparian forests occurring in this region, the entire “Uroczysko Wielkie Łunawy” should be protected.
PL
„Uroczysko Wielkie Łunawy” należy do obiektów wyróżniających się znacznymi walorami florystycznymi. Urozmaicona i mało zdegenerowana flora tego obiektu liczy 192 taksony roślin naczyniowych z 60 rodzin, w tym 41 taksonów roślin drzewiastych. Odnaleziono stanowiska 13 gatunków podlegających ochronie prawnej. Zachowały się tu cenne fragmenty zbiorowisk grądów i łęgów oraz drzewostany zbliżone do naturalnych. „Uroczysko Wielkie Łunawy” należałoby objąć ochroną ze względu na występujące tu, a dość rzadkie w regionie, dobrze zachowane zbiorowiska lasów grądowych i łęgowych.

The paper deals with the richness and diversity of endemic and subendemic taxa in the Polish Carpathians. Based on critical studies in the literature and the authors' unpublished materials collected in the field, the distribution patterns of endemic species are analysed and discussed. The participation of endemics in the flora of single Carpathian ranges is assessed and analysed. The importance of the Tatra Mts as a centre of endemism is stressed. The frequency and altitudinal ranges of endemic taxa are characterized and their syntaxonomical spectrum is presented.

The 96 Vascular plant species belonging to 36 families have been identified in “Jamno” nature reserve during field investigations which were done in 2011. The species represent different types of growth (= life forms in Raunkiaer”s classification system), With hemicryptophytes being the dominant form. The fiora contains plants from Various ecological groups depending on light requirements, moisture of the soil, soil acidity and soil trophy. Most of the plants tolerates shaded and semi-shaded sites, fresh and moderately acid or nearly neutral soils of intermediate fertility. The indigenous forest species are the most valuable components of flora. Among them Convallaria majalis, Frangula alnus and Viburnum opulus are protected by law. The parasite plant Monotropa hypopitis and half-parasites: Viscum abietis, Malampyrum nemorosum and Melampyrum pratense, are “botanical curiosities” of the reserve.
