Opis:
The accumulation of lead, cadmium, iron, nickel, copper and zinc in the femora of yellow-necked mouse (Apodemus flavicollis) and bank vole (Clethrionomys glareolus) living near the site of coal power station Novaky (Slovakia) was investigated. The content of heavy metals in the bones was assessed by atomic absorption spectrophotometry method. Altogether 20 femora of adult individuals were analysed. Higher concentrations of Cd, Ni, Cu and Zn were detected in the bones of bank vole. Significant differences were observed for the concentrations of Cd, Ni and Zn (p < 0.05). On the contrary, higher concentrations of Pb and Fe were found in the femora of yellow necked mouse. However, the differences were not significant. Our results indicate that Clethrionomys glareolus may be considered as more bone loaded zoomonitor in comparison with Apodemus flavicollis.
Zbadano kumulację ołowiu, kadmu, żelaza, niklu, miedzi i cynku w kości udowej myszy leśnej (Apodemus flavicollis) i nomicy rudej (Clethrionomys glareolus) zasiedlających tereny w pobliżu elektrowni Novaky na Słowacji. Zawartość metali ciężkich w kościach zmierzono metodą spektrofotometrii atomowej. Przebadano 20 kości udowych podchodzących od dorosłych osobników. Większe zawartości Cd, Ni, Cu i Zn stwierdzono w kościach nornicy rudej niż w kościach myszy leśnej. Istotne statystycznie różnice między badanymi ssakami dotyczyły zawartości Cd, Ni i Zn (p < 0.05). Z drugiej strony kości myszy leśnej zawierały więcej Pb i Fe niż kości nomicy rudej. Różnice te nie były jednak istotne statystycznie. Uzyskane wyniki wskazują, że kości nornicy rudej kumulują więcej metali ciężkich niż kości myszy leśnej, co może mieć znaczenie dla przyszłych badań monitoringowych.

Opis:
The aim of the study was to investigate the pattern of daily activity and connections between daily and spatial activity in relation to the forest undergrowth phytocenosis of the two most common rodent species – bank vole Myodes (Clethrionomys) glareolus (Cricetidae) and yellow−necked mouse Apodemus flavicollis (Muridae). The research was carried out in July 2017 in the oak−hornbeam habitat in the Browsk Forest District in the northern part of the Białowieża Forest. For rodents catching and vegetation evaluation the 1 ha study plot was divided into 100 squares of 10×10 m. Catches were made according to the catch−mark−release method. Wooden live traps (with bait and food for caught animals in the form of the grains of cereals, juicy fruits and aromatic fat) were set in the center of each square. The traps were controlled during 4 days at 3−hour intervals (0 a.m., 3 a.m., 6 a.m., 9 a.m., 12 p.m., 3 p.m., 6 p.m. and 9 p.m.). Traps occupied by rodents were marked with colored adhesive cards according to the established code. Twice a day – at 6 a.m. and 6 p.m. caught rodents were identified to the species and released next to the traps. The catch time was recorded. In total, 151 catches were registered. The daily activity of rodents was determined based on the total catches into assumed time intervals and at different times of the day (day, night, dawn/twilight). We provided a detailed description of undergrowth features of the area where rodents were caught. In each square we assessed the dominant species (on this basis the plants communities were established), the average height of vegetation and the degree of soil coverage with plants (undergrowth density). Collected data were used to the interpretation of the spatial activity of rodents in relation to the different undergrowth characteristics. The bank vole was distinguished by an even, day−and−night activity rhythm, while the yellow−necked mouse by monophasic – remarkably nocturnal activity. The dependence of the phytocenosis characteristics and spatial distribution of rodents was revealed for the daily activity of bank vole and twilight−dawn activity of both species. At dawn and dusk voles and mice were active in places with high vegetation. The density of undergrowth was the most important feature for bank voles during the day.

Opis:
The studies were carried out in Kosewo Górne in the Mazurian District (North-East region of Poland), in September 1995, September 1996 and between May 1997 and June 1998 each month. The animals were trapped in live traps, and after study they were marked and released. The infection of trypanosomes was detected using microhaematocrit centrifugation technique and in blood smears. The intensity of infection had the range from 50 to 150000 individuals in 1ml of blood. The maximal prevalence of infection was in August and September and there were 45% and 38% of infected voles respectively. The infection was detected also in May 1998, in other months the prevalence had low level. There were no individuals of bank vole infected in succecding months. The females of bank vole are more often infected with trypanosomes than males.

Opis:
Copper is a physiologically occurring trace element, the availability of which to wild small mammals is constantly increasing. This research deals with the questions of how copper in doses equivalent to those found in the natural environment from polluted areas (Cu I – 150 mg kg-1, Cu II – 600 mg kg-1) influences homeostasis of small rodents. The following were used as indicators: ratios of organs to body mass, blood parameters (haematocrit, haemoglobin), copper, iron and zinc concentrations in selected tissues and in excrements. The bank vole was used as a model species (n = 72). Haematocrit was assessed using a haematocrit reader, while haemoglobin was determined with a spectrophotometer. The content of Cu, Fe and Zn was analyzed using the flame method. Ratios of the liver and kidneys to body mass were significantly lower in animals exposed to 600 mg kg-1 Cu than in the control. Copper accumulated in the liver, kidneys, brain and excrements of the Cu II animals of both sexes. It also influenced the iron and zinc homeostasis by decreasing the iron concentration in the kidneys of both sexes, in the liver of females and in male testes. Additionally, it caused a decline in iron excretion in females. Compared to the control, the zinc concentration was significantly higher in the liver and brain of animals exposed to copper solutions as well as in the kidneys of copper treated males. Along with an increase in copper, the zinc concentration in faeces decreased significantly. In conclusion, copper pollution influences negatively the homeostasis of small mammals. Consequently it may interfere with trophic chains, which could affect adversely the degree of biodiversity.

Opis:
Pneumocystosis (Pneumocystis carinii pneumonia) is a parasitic disease which in Lithuania used to be diagnosed only with the use of pathohistological methods. The aim of our study was to determine prevalence of P. carinii antibodies among children and women, using immunochemical method (ELISA) and to find out which groups of patients have higher antibody titres. We also addressed the question of infection with P. carinii among rodents. After investigating 9 species of rodents it was found that mostly infected is brown rat (Rattus norvegicus) - 42.9% of them were found infected. The least infected was bank vole (Clethrionomys glareous)- 5.9. %. The brown rat lives on hatch of domestic birds, rabbits or drinks eggs, while rodents in nature live on insects, molluscs, amphibians etc. European water voles (Arvicola terrestris) and field voles (Microtus arvalis) are vegetable feeders. Our data shows that those species of rodents were not infected with pneumocysts.
