“…In the present work, high SCE incidence was observed in the proximal and distal regions of the coypu and rabbit chromosomes. In the coypu, these regions are largely formed by constitutive heterochromatin (ILIKER et al 2009). Heterochromatin is principally located in the centromere region in rabbits as well.…”

“…All the autosomes have two arms: 32 of them metacentric and 8 submetacentric. The X sex chromosome is metacentric, and Y -the smallest of all -is acrocentric (FREDGA 1966, TSIGALIDOU 1966HSU & BENIRSCHKE 1971;ILIKER et al 2009). The banding pattern standard for coypu chromosomes has not been published, although several reports have offered preliminary distributions of C bands in the chromosomes (PIEÑKOWSKA et al 1994;ILIKER et al 2009;KUCHTA et al 2009).…”

Moreover cytogenetic analysis of nucleolar organizer regions (NORs) revealed the presence of 2 active NORs in the coypu karyotype (PIEÑKOWSKA & OEWITOÑSKI 1993).The use of the G-banding method has produced a more detailed characterization of the karyotype (LUNGEANU et al 1980).…”

The effect of bromodeoxyuridine on spontaneous sister chromatid exchange frequency in rabbit (Oryctolagus cuniculus) and coypu (Myocastor coypu) chromosomes. Folia Biologica (Kraków) 64: 89-96. The sister chromatid exchange test is regarded as a highly sensitive cytogenetic assay. It measures chromosome sensitivity to particular damage factors and provides information on control and repair mechanism performance. It is instrumental in the early identification of the effects of noxious factors present in the habitat. This investigation was aimed at identifying sister chromatid exchange sites in coypu and rabbit chromosomes, as well as determining the spontaneity of the process by applying different BrdU doses. The chromosomes were obtained from an in vitro culture of blood lymphocytes, supplemented with 4 different BrdU doses: 0.25/0.5/1.0/2.5 µg/ml in order to identify spontaneous sister chromatid exchanges in both animal species. The chromosomes were stained according to the FPG method. Spontaneous SCEs were observed in coypu at a concentration of 1.0 µg/ml, and in rabbits at 0.5 µg/ml. The mean SCE/cell incidence was 1.41±1.15 in coypu, and 2.69±2.14 in rabbits. Differences in SCE incidence were identified between the analysed animal species and the applied BrdU doses.

“…In the coypu karyotype (2 n = 42), all the autosomes are bi‐armed: 32 are metacentric and 8 are submetacentric. The X sex chromosome is metacentric and the Y is the smallest chromosome of all (Dziedzina, Szeleszczuk, Dulęba, & Niedbała, 2003; Iliker, Arslan, Pamukoğlu, & Albayrak, 2009; Kuchta, Szeleszczuk, Niedbała, & Onderka, 2009). One of the principal methods to determine the impact of environmental pollution on animals is biomonitoring.…”

Coypus (Myocastor coypu) are fur-bearing herbivores native to South America (Gosling & Berker, 1991). In European countries, coypus have been bred since the 1920s (Carter & Leonard, 2002). In Poland, coypu breeding experienced a decline in the late 1990s and the number of animals began to fall quickly. Although coypu pelts and meat are valuable, there was no demand for these products (Kowalska & Niedbała, 2014). Furthermore, coypu breeding was adversely affected by environmental movement campaigns and rising farm maintenance costs. For this reason, coypus were included in a genetic resources conservation program for native breeds, which is aimed to preserve and increase population size while maintaining genetic variation in the coypu (http://www.bioro znoro dnosc.izoo.krakow. pl). The loss of interest in the breeding of this species did not prevent researchers from conducting numerous studies, including the determination of genetic diversity in the populations and karyotype characterization using available cytogenetic techniques (Kaplanova et al., 2012). In the coypu karyotype (2n = 42), all the autosomes are bi-armed: 32 are metacentric and 8 are submetacentric. The X sex chromosome is metacentric and the Y is the smallest chromosome of

ASTRACT: Gala Lake National Park (GLNP) consists of terrestrial and aquatic ecosystems covering 6.087 hectares of area in Enez and İpsala district boundaries of Edirne province. Extensive field studies were performed on mammals within the boundaries of GLNP for 26 days from 29 July to 07 November 2016. A total of 44 mammalian species from 16 families within 6 orders were determined in the studied area and an up-to-date inventory of mammals was prepared. Myocastor coypus (coypu) were detected as an invasive species in the region.
