    Are the Forests of the Wigry National Park Suitable for the Common Dormouse Muscardinus avellanarius?
    (Wydawnictwo Uczelniane Zachodniopomorskiego Uniwersytetu Technologicznego w Szczecinie, 2018) Gruszczyńska, Joanna; Grzegrzółka, Beata; Misiukiewicz, Wojciech; Department of Genetics and Animal Breeding, Warsaw University of Life Sciences – SGGW, Poland; Wigry National Park, Krzywe, Poland
    The research was aimed at demonstrating whether the common dormouse Muscardinus avellanarius occurs in the area of the Wigry National Park. In order to detect the presence of this species, research areas in park stands were determined, characterized by a large share of hazel Coryllus avellana in the undergrowth. Hazel nuts gnawed by the species were sought on the 30 forest research plots. Nesting tubes, placed in May, and nest boxes for birds were checked till the first days of October. In addition, the summer nests of the species were searched. During the research, 6 nests of common dormouse were found and one individual of this species was observed. The results show that, despite the fact that the common dormouse is on the list of mammalian species found in the Wigry National Park, it rarely occurs there.

    Genetic Background and Effects of Excessive Iron Storage in Different Mammalian Species
    (Wydawnictwo Uczelniane Zachodniopomorskiego Uniwersytetu Technologicznego w Szczecinie, 2018) Florczuk-Kołomyja, Patrycja; Kołomyja, Paweł; Gruszczyńska, Joanna; Department of Genetics and Animal Breeding, Warsaw University of Life Sciences – SGGW, Poland
    Hemochromatosis is a metabolic disease associated with excessive iron storage in the body. At present, we distinguish between 5 types of this disease that differ in their genetic background and inheritance, as well as the frequency of occurrence. Due to the possibility of fatalities, excessive iron storage is a more serious disorder than its deficiency. In this disease, iron is accumulated in the body in the form of hemosiderin, a protein complex that store iron in cells. The occurrence of this disease was observed not only in humans, but also in other animal species such as the red deer, black rhinoceros, house mouse or domestic cattle. This article is a review of the current state of knowledge about hemochromatosis in humans, normal iron metabolism, and about the occurrence of this disease in the red deer and its impact on the biology and population of this species.

    Genome Comparative Studies in the Phasianidae Family. Part I. Genome Comparative Studies in the Phasianidae Family between Domestic Chicken (Gallus gallus domesticus) and Wild Turkey (Meleagris gallopavo)
    (Wydawnictwo Uczelniane Zachodniopomorskiego Uniwersytetu Technologicznego w Szczecinie, 2018) Gruszczyńska, Joanna; Grzegrzółka, Beata; Morawska, Agnieszka; Department of Genetics and Animal Breeding, Warsaw University of Life Sciences – SGGW, Poland
    In studies aimed at understanding the genome of turkey, the great facilitation was the use of genetic sequences and markers previously used to study the chicken genome. This solution was possible due to the fact that domestic chicken and wild turkey are phylogenetically related species with a common ancestor. In numerous analyses using chicken sequence, positive results of amplification of the turkey sequence were obtained, which accelerated the recognition of the genome of this species.

    The Occurence of the Eurasian Otter Lutra Lutra in Aquatic Habitats of Different Trophy in Wigry National Park
    (Wydawnictwo Uczelniane zachodniopomorskiego Uniwersytetu Technologicznego w Szczecinie, 2018) Romanowski, Jerzy; Januszewicz, Małgorzata; Grzegrzółka, Beata; Faculty of Biology and Environmental Studies, Cardinal Stefan Wyszyński University in Warsaw, Warszawa, Poland; Wigry National Park, Krzywe 82, Suwałki, Poland; Department of Genetics and Animal Breeding, Warsaw University of Life Sciences – SGGW, Poland
    The standard method was used for the first field survey of the Eurasian otter Lutra lutra distribution in all aquatic habitats in Wigry National Park (WNP) in northern Poland. Total of 59 study sites (48 on lakes, 8 on rivers and 3 on drainage ditches) were visited twice between 12th and18th of March and between 8th and 13th of May 2018. Signs of otters were found in 42 (71.2%) sites located throughout the whole area of Wigry National Park. The percentage of positive sites reached 100% in mesotrophic and eutrophic lakes as well as in rivers and meliorated canals. No signs of otter presence were recorded in dystrophic lakes located in the centre of peat-bogs. This marked difference in otter occurrence can be explained in the terms of different food availability: high in mesotrophic and eutrophic habitats and low in dystrophic lakes.
