The presence of alien plants in the coastal zone of Charzykow-skie Lake SUMMARY
In the last century,
the process of introducing alien species has intensified due to the
massive infrastructure development and trade exchange. Penetration of
the protected areas by non-native species constitutes a serious
problem.
Aculeata
(Hymenoptera) of Kampinos National Park. SUMMARY
The paper presents
information about the presence of digger wasps (Hymenoptera:
Sphecidae, Crabronidae) in the Kampinos National Park
in Central Poland. The specimens were collected using water pan traps
(‘‘Moerike-traps'') during the years 1999 - 2006. Research
was carried out on wooden buildings situated in the Park and its
vicinity (2000 - 2001), as well as in open, anthropogenic habitats
including abandoned arable fields and grasslands under succession
(1999 and during 2002 - 2006).
Caddisflies (Trichoptera) of the nature reserve "Źródlisko Skrzypowe" SUMMARY Caddisflies were studied in "Źródlisko Skrzypowe" nature reserve in 2006 (April, May and July). In total, 53 specimens were collected, representing 9 species. The reophilous species of Halesus digitatus/tesselatus clearly dominated in the collected material (due to the fact that larvae of the two species were highly similar, it was impossible to distinguish one from the other). Among crenophilous species two were recorded: Potamophylax nigricornis and Limnephilus elegans.As for Glyphotaelius pellucidus, it was characteristic of seasonal spring waters. Especially noteworthy from a sozological perspective was the presence of two species: Limnephilus elegans, featured on the Red List under DD category, and Stenophylax vibex, which had been recorded in Poland for the first time in 2006, in Greater Poland. Stenophylax vibex has also been encountered in Świętokrzyski National Park and the distribution of this species in Poland is probably expanding. Recording the presence of Stenophylax vibex in "Źródlisko Skrzypowe" nature reserve supplements the knowledge about the distribution of this species in Poland.
Herpetofauna of the Dziki Staw nature reserve SUMMARY
The forest nature
reserve "Dziki Staw" ("Wild Pond") in Rytwiany is located in
the eastern part of the Świętokrzyskie voivodeship (central
Poland). The reserve covers 6.52 ha and includes a small karstic lake
(area of 2.16 ha) surrounded by a wet meadow, alder forests and mixed
woods. Large fish ponds are located in the vicinity of the reserve.
Together with the lake they provide favorable conditions for breeding
amphibians.
Recolonization of
the Magurski National Park SUMMARY The reintroduction of the European beaver Castor fiber in the Beskid Niski was conducted in the years 1980 to 1985 after almost 400 years of absence of the species in this area. 16 years after the first reintroduction there was an inventory of European beavers positions conducted within the Magurski National Park. Five families were observed and a total population was estimated to be 23 - 26 individuals. Studies on the distribution and abundance of this species in the Magurski NP were performed again in the spring of 2007. They consisted of an inspection of all watercourses and open waters within the boundaries of the park. The population of the European beaver in the study area was defined on the basis of the assumption that the beaver family in Poland usually consists of 4 individuals. 11 localities were identified as inhabited by the European beaver families. Population was estimated at 44 individuals. Most families (5) were observed on the Ryjak stream and its surroundings. Due to the difficult mountainous conditions, the recolonization rate is relatively low, but the population seems to be stable and its numbers are steadily increasing. During research,15 species of trees and shrubs eaten by beavers were found (Table 1).
Nature and
landscape values of reserves in the SUMMARY
Międzychodzko-Sierakowskie
Lakeland has high natural and landscape values. It is considered as a
model area for a variety of research activities due to the presence
of multiple geomorphological forms. The particularly important
natural elements of the Lakeland are nature reserves. This study was
aimed at providing accurate analysis of the value of reserves
regarding potential attractiveness for visitors and an assessment of
the impact of tourism on nature reserves.
Short floristic, faunistic and micobiotic notes
Materials for
bryoflora of the Golcowe Bagno NatureReserve SUMMARY The Golcowe Bagno Nature Reserve was established for protection of peatland with natural vegetation (ZARZĄDZENIE... 1990). Bryological studies were conducted in 2006. We found 31 species of mosses and 6 liverworts. Distribution of all identified species is shown on the map (Fig. 1). We did not confirm the presence of localities of six taxa previously reported by JASNOWSKA and JASNOWSKI (1988) - Sphagnum balticum, S. centrale, S. contortum, S. obtusifolium, S. platyphyllum and S. rubellum. These species are considered as rare in Western Pomerania (JASNOWSKI 1962; JASNOWSKA, JASNOWSKI 1988; MELOSIK, URBAŃSKI 1997; WILHELM, WIĘCŁAW 2011). Bryoflora of nature reserve contains 10 taxa under strict protection and 14 under partial protection (ZARZĄDZENIE... 2012). Most of the valuable taxa were found in the bog. One liverwort species - Cladopodiella fluitans is threatened with extinction in Poland (KLAMA 2006).
A locality of
land snail Cepaea vindobonensis SUMMARY A new locality of a land snail Cepaea vindobonensis was found at Gacki near Pińczów (50°27'30"N, 20°35'38"E, UTM DA69). The presence of C. vindobonensis was observed on the slopes (SE, E) of gypsum quarry with xerothermic and ruderal vegetation.
Monitoring of the
butterflies (Rhopalocera) of the Magura National Park SUMMARY
Faunistic inve
stigation of butterflies of the Magura National Park was carried out
in 1997 - 1998 by KOSIOR and WITKOWSKI (2000). The investigation
has shown the presence of 74 species of butterflies. Taking the same
monitoring positions creates an opportunity to observe the processes
that take place while the fauna of butterflies changes. However,
before the complete monitoring will be carried out, in 2012 a pilot
program has been implemented. It covered five selected locations:
Ciech, Rostajne, Nieznajowa, Polany and Kotan. The research positions
were chosen in a specific way, so that they reflect the two types of
origin and usage of non-forest land. |
