Reproductive failure in moose () due to embryonic mortality and unfertilized oocytes.

Acta Theriol (Warsz) 2014 15;59:449-455. Epub 2013 Dec 15.

Division of Reproduction, Department of Clinical Sciences, Swedish University of Agricultural Sciences, Box 7054, SE-750 07 Uppsala, Sweden.

Knowledge on reproductive success is vital for successful management of large ungulates and is often measured by means of observing surviving offspring. In harvested ungulates, postmortem investigations of reproductive organs are used to estimate reproductive potential by obtaining ovulation rates and fetus numbers. However, there are differences in numbers of offspring observed, fetal/embryo counts, and ovulation rates. Read More

The influence of habitat structure on genetic differentiation in red fox populations in north-eastern Poland.

Acta Theriol (Warsz) 2014 22;59:367-376. Epub 2014 Mar 22.

Mammal Research Institute, Polish Academy of Sciences, 17-230 Białowieża, Poland.

The red fox () has the widest global distribution among terrestrial carnivore species, occupying most of the Northern Hemisphere in its native range. Because it carries diseases that can be transmitted to humans and domestic animals, it is important to gather information about their movements and dispersal in their natural habitat but it is difficult to do so at a broad scale with trapping and telemetry. In this study, we have described the genetic diversity and structure of red fox populations in six areas of north-eastern Poland, based on samples collected from 2002-2003. Read More

Environmental factors shaping ungulate abundances in Poland.

Acta Theriol (Warsz) 2013 29;58:403-413. Epub 2013 Jun 29.

Mammal Research Institute, Polish Academy of Science, ul. Waszkiewicza 1, 17-230 Białowieża, Poland.

Population densities of large herbivores are determined by the diverse effects of density-dependent and independent environmental factors. In this study, we used the official 1998-2003 inventory data on ungulate numbers from 462 forest districts and 23 national parks across Poland to determine the roles of various environmental factors in shaping country-wide spatial patterns of ungulate abundances. Spatially explicit generalized additive mixed models showed that different sets of environmental variables explained 39 to 50 % of the variation in red deer , wild boar , and roe deer abundances.

Complex patterns of population genetic structure of moose, , after recent spatial expansion in Poland revealed by sex-linked markers.

Acta Theriol (Warsz) 2013 11;58:367-378. Epub 2013 May 11.

Institute of Biology, University of Białystok, Świerkowa 20B, 15-950 Białystok, Poland.

In recent years, human activity directly and indirectly influenced the demography of moose in Poland. The species was close to extinction, and only a few isolated populations survived after the Second World War; then, unprecedented demographic and spatial expansions had occurred, possibly generating a very complex pattern of population genetic structure at the present-day margins of the species range in Poland. Over 370 moose from seven populations were collected from Poland, and partial sequences of the mitochondrial control region (mtDNA-cr; 607 bp) were obtained. Read More

Cytochrome gene () sequence diversity in a population from Bialowieza Primeval Forest.

Acta Theriol (Warsz) 2013 Apr 5;58(2):119-126. Epub 2012 Sep 5.

Museum and Institute of Zoology, Polish Academy of Sciences, Wilcza 64, 00-679 Warsaw, Poland.

Based on published information about the glacial, postglacial, and recent distribution of the root vole, , we hypothesized that a population inhabiting the pristine wetland in eastern Poland (Bialowieza Primeval Forest) might comprise a high diversity of haplotypes. The support for this hypothesis was provided by an analysis of partial gene sequences from 149 voles sampled within a two-hectare plot during a nine-year study. In this population, we identified eight haplotypes (PLB1-PLB8), four of which were new to the root vole. Read More

The effect of landscape structure on the distribution of brown hare Lepus europaeus in farmlands of Germany and Poland.

Acta Theriol (Warsz) 2013 Jan 18;58(1):39-46. Epub 2012 Aug 18.

Polish Hunting Association, Research Station, ul. Sokolnicza 12, 64-020 Czempiń, Poland.

Habitat management should be an important part of the brown hare (Lepus europaeus) conservation, but the habitat requirements of this species are not fully recognised. The aim of our research was to estimate these requirements by analysing the effect of various agricultural landscape structure features on the distribution of hares in five agricultural areas in Germany and Poland. The local density of hares was assessed in the spring and autumn of 2006 by using the method of spotlight-strip counts on 9-15 subareas in each research region. Read More

Seasonal and photoperiodic effects on lipid droplet size and lipid peroxidation in the brown adipose tissue of bank voles (Myodes glareolus).

Acta Theriol (Warsz) 2012 Oct 18;57(4):289-294. Epub 2012 May 18.

Institute of Biology, University of Bialystok, Świerkowa 20B, 15-950 Białystok, Poland.

Seasonal changes in lipid droplet size and lipid peroxidation in the brown adipose tissue (BAT) of wild bank voles were examined. In addition, a role of photoperiod in these changes was studied; bank voles were held from the birth under long photoperiod (LP) for 12 weeks, and then half of them was transferred to short photoperiod (SP) for 6 weeks and another one remained under LP. In the wild bank voles the absolute BAT weight was seasonally constant, while the significant differences in the lipid droplet size were observed. Read More

Cyclic voles and shrews and non-cyclic mice in a marginal grassland within European temperate forest.

Acta Theriol (Warsz) 2012 Jul 14;57(3):205-216. Epub 2012 Feb 14.

Mammal Research Institute, Polish Academy of Sciences, 17-230 Białowieża, Poland.

Cyclic population dynamics of small mammals are not restricted to the boreal and arctic zones of Eurasia and North America, but long-term data series from lower latitudes are still less common. We demonstrated here the presence of periodic oscillations in small mammal populations in eastern Poland using 22-year (1986-2007) trapping data from marginal meadow and river valley grasslands located in the extensive temperate woodland of Białowieża Primeval Forest. The two most common species inhabiting meadows and river valleys, root vole Microtus oeconomus and common shrew Sorex araneus, exhibited synchronous periodic changes, characterised by a 3-year time lag as indicated by an autocorrelation function.

Identification of the barrier to gene flow between phylogeographic lineages of the common hamster Cricetus cricetus.

Acta Theriol (Warsz) 2012 Jul 28;57(3):195-204. Epub 2012 Feb 28.

In anthropogenically disturbed habitats, natural barriers still exist and have to be recognized, as they are important for conservation measures. Areas of phylogeographic breaks within a species are often stabilized in inhospitable regions which act as natural barriers. An area of contact between phylogeographic lineages of the common hamster (Cricetus cricetus) was found in the Małopolska Upland in Poland. Read More

Drive counts as a method of estimating ungulate density in forests: mission impossible?

Acta Theriol (Warsz) 2011 Jul 29;56(3):239-253. Epub 2011 Jan 29.

Although drive counts are frequently used to estimate the size of deer populations in forests, little is known about how counting methods or the density and social organization of the deer species concerned influence the accuracy of the estimates obtained, and hence their suitability for informing management decisions. As these issues cannot readily be examined for real populations, we conducted a series of 'virtual experiments' in a computer simulation model to evaluate the effects of block size, proportion of forest counted, deer density, social aggregation and spatial auto-correlation on the accuracy of drive counts. Simulated populations of red and roe deer were generated on the basis of drive count data obtained from Polish commercial forests. Read More

Molecular biogeography of red deer Cervus elaphus from eastern Europe: insights from mitochondrial DNA sequences.

Acta Theriol (Warsz) 2011 Jan 16;56(1):1-12. Epub 2010 Nov 16.

European red deer are known to show a conspicuous phylogeographic pattern with three distinct mtDNA lineages (western, eastern and North-African/Sardinian). The western lineage, believed to be indicative of a southwestern glacial refuge in Iberia and southern France, nowadays covers large areas of the continent including the British Isles, Scandinavia and parts of central Europe, while the eastern lineage is primarily found in southeast-central Europe, the Carpathians and the Balkans. However, large parts of central Europe and the whole northeast of the continent were not covered by previous analyses. Read More
