30-Year-Long Changes in Terrestrial Vertebrate Fauna of Niebieskie ŹródłA (Blue Springs) Nature Reserve in Tomaszów Mazowiecki, Central Poland
The article focuses on changes in terrestrial vertebrate fauna of Niebieskie Źródła (Blue Springs) Nature Reserve that occurred between two censuses carried out in the area. The first census was carried out in the period of 1968-1970, and the second census in the period of 1998-1999. In 1998-1999 the occurrence of four species of amphibians, 41 of birds and 15 of mammals was recorded. In comparison with investigations from 1968-1970 two species of amphibians, two species of mammals, and nine species of birds were found to have disappeared from the reserve. In the census carried out in 1998 and 1999 we recorded 22 new species of vertebrates: one new species of amphibian, five species of mammals, and 16 species of birds. The recent observations showed a decline in the abundance of amphibian species in the reserve, especially in the closest vicinity to the urban development around the city of Tomaszów Mazowiecki. The quantitative data on birds showed an increase in the numbers and abundance, which was mainly pronounced in the group of forest species, especially cavity and shrub nesters. We suggest that these changes are directly related to the succession of forest vegetation and its developing vertical structure, as well as to an increase in the forestation of the reserve area
Distribution of amphibians and reptiles in central Poland: 1980-2000
Based on 3047 records from 97 recorders distribution maps were drawn for the
amphibians and reptiles of central Poland (lirom 51°00’N to 52°15’N and from 18°20’E to
20°20’E). The study area was divided into 180 atlas fields based on the geographic grid. All
data were gathered in 1980-2000, most of them (67%) however, in 1995-2000. 13 taxa of
amphibians were found in 143 atlas fields and 6 species of reptiles were found in 121 atlas
fields. The amphibians were (given with the number of atlas fields with the species found):
119 - Common frog Rana temporaria Linnaeus, 1758; 114 - Common toad Bufo bufo
(Linnaeus, 1758); 97 - Moor frog Rana arvalis Nilsson, 1842; 94 - Fire-bellied toad Bomhina
bombina (Linnaeus, 1761); 93 - Pool frog Rana lessonae Camerano, 1882; 87 - Tree frog
Hyla arhorea (Linnaeus, 1758); 85 - Green toad Bufo viriiüs Laurenti, 1768; 72 - Smooth
newt Triturus vulgaris (Linnaeus, 1758); 70 - Spadefoot Pelobales fuscus (Laurenti, 1768); 69
- Edible frog Rana kl. esculenia Linnaeus, 1758; 39 - Great crested newt Triturus cristatus
(Laurenti, 1768); 30 - Marsh frog Rana ridibunda Pallas, 1771 and 28 - the Natterjack Bufo
calamita Laurenti, 1768. The reptile species (given with the number o f atlas fields) were: 94
- Sand lizard Lacerta agilis Linnaeus, 1758; 72 - Slow-worm Anguis fragilis Linnaeus, 1758;
67 - Common lizard Lacerta vivipara Jacquin, 1787; 60 - Grass snake Natrix natrix (Linnaeus,
1758), 57 - Adder Vipera berus (Linnaeus, 1758) and 4 - the Smooth snake Coronella austriaca
Laurenti, 1768. Six adult specimens of the European pond terrapin Emys orbicularis (Linnaeus)
were also found, but breeding of this species in the area studied was not confirmed.Zadanie pt. „Digitalizacja i udostępnienie w Cyfrowym Repozytorium Uniwersytetu Łódzkiego kolekcji czasopism naukowych wydawanych przez Uniwersytet Łódzki” nr 885/P-DUN/2014 dofinansowane zostało ze środków MNiSW w ramach działalności upowszechniającej naukę
Breeding birds community of oak-hornbeam reserves in Pilica Forest
From 1979 to 1981 investigations of breeding birds communities were
conducted in four oak-hornbeam reserves situated in Pilica Forest. In the „Błogie” and
„Gaik” reserves the abundance of breeding birds was determined by using mapping
technique in two subsequent breeding seasons. A total of 66 breeding bird species within
the area of this reserves was recorded. The highest number 61 species was found in the
„Błogie” reserve and lower number 48, 44 and 31 in the „Jeleń”, „Gaik” and „Spała”
reserves respectively. The density of pairs ranged from 92 to 122 per 10 ha. The group of
dominant species always consisted of five bird species: Sturnus vulgaris, Fringilla coelebs,
Erithacus rubecula, Phylloscopus sibilatrix, Parus major.Zadanie pt.

The occurrence of black stork Ciconia nigra (L.), black grouse Tetrao tetrix (L.) and hazel hen Bonasa bonasia (L.) in Łódź region (The results of an enquiry)
This paper presents the results of enquiry sent (in 1994) to the forest district
administration in Łódź (Central Poland), concerning three forest bird species: black stork,
black grouse and hazel hen. Compared to the results of older study (from 1972) the increase
of black stork population is distinguishable (now about 50 breeding pairs) contrary to abruptly
decreased numbers of the other two species.Zadanie pt. „Digitalizacja i udostępnienie w Cyfrowym Repozytorium Uniwersytetu Łódzkiego kolekcji czasopism naukowych wydawanych przez Uniwersytet Łódzki” nr 885/P-DUN/2014 dofinansowane zostało ze środków MNiSW w ramach działalności upowszechniającej naukę
Characterization of the selected population parameters of the white stork (Ciconia ciconia) In Central Poland
On the basis of the so far collected and/or published data on the White Stork of
central Poland (the Łódź Upland) the authors undertook an attempt to explain the
spatial and tem poral distribution of breeding efficiency, population density as well as
nests localization and nest distribution in relation to human settlements.
The efficiency of White Stork breeding depends on biotopic conditions and
interspecific competition. Precipitation in spring has a positive while precipitation and
low temperatures in June a negative impact on interspecific competition.
Habitat conditions of the White Stork have begun to display a constant tendency to
decrease in quality, mainly due to land draining.
The interspecific competition depends on biotopic conditions and on density.
Optimal habitat conditions, including weather ones, may largely neutralize the impact
of the intraspecific competition, which enables the population an increase in density,
leading even to the appearance of aggregations and colonies. A deterioration in habitat
conditions increases interspecific competition, which decreases breeding success to
a lower extent than that which could be expected, caused decomposition of aggregations
and decrease in the density of breeding pairs. The appearance of a nest outside of the
settlement area is a result of interspecific competition.Zadanie pt. „Digitalizacja i udostępnienie w Cyfrowym Repozytorium Uniwersytetu Łódzkiego kolekcji czasopism naukowych wydawanych przez Uniwersytet Łódzki” nr 885/P-DUN/2014 dofinansowane zostało ze środków MNiSW w ramach działalności upowszechniającej naukę
