Cím:	Recent range expansion of Pomatias rivulare (Eichwald, 1829) (Mollusca: Pomatiidae) in Central-Eastern Europe / Fehér Zoltán, Szabó Krisztián, Bozsó Miklós, Pénzes Zsolt
Dátum:	2009
ISSN:	1217-8837
Megjegyzések:	We have investigated the diversity of mitochondrial COI gene sequences of Pomatias rivulare populations, originated from the western edge of the species' area. COI gene has not shown any variability, the same haplotype was found in all of the examined Hungarian, Romanian, Serbian and Montenegrin populations, which arises most probably from a rapid range expansion. Based on it, we can rule out that Hungarian populations are relicts and we can concludethat the Pannonicum, the Southern Carpathians and the Eastern Dinarids were colonized veryrecently, most probably in the Holocene.

Cím:	Intersexual size and plumage differences in tree sparrows (Passer montanus) : a morphological study based on molecular sex determination / F. Mónus, K. Szabó, A. Lózsa, Z. Pénzes, Z. Barta
Dátum:	2011
ISSN:	1217-8837
Megjegyzések:	We investigated intersexual morphological differences in tree sparrows (Passer montanus), a species being considered as sexually monomorphic. Molecular sexing of the birds was performed by PCR amplification of the sex chromosome-linked CHD1 gene introns. All measured traits (body weight, wing, tail and tarsus length, bill size and the size of the black throat patch, i.e. badge hereafter) were greater in males than in females and the sex of about 90% of the individuals was correctly categorized by means of a discriminant analysis based on the morphological measurements. Nevertheless, wing length alone was equally good predictor of the sex. Other measured traits had only moderate discriminant value. Our results do not support that tree sparrows can be sexed based on the size of their badge alone. However, some of our results suggest intersexual differences in the function of the badge.

Cím:	High turnover rate revealed by non-invasive genetic analyses in an expanding Eastern Imperial Eagle population / Vili Nóra, Szabó Krisztián, Kovács Szilvia, Kabai Péter, Kalmár Lajos, Horváth Márton
Dátum:	2013
ISSN:	1217-8837
Megjegyzések:	In this study we estimated the annual turnover rates, and so indirectly the possible maximum mortality rates of female Eastern Imperial Eagles (Aquila heliaca) in an expanding population. DNA was extracted from shed feathers collected in territories where at least three consecutive years of breeding occurred. As DNA samples could not be obtained at every studied nest in each year, minimum and maximum turnover rates were estimated. The calculated rates, 27.7% (minimum) and 35.5% (maximum), are much higher than what could be expected based on studies of other raptor species. According to previous studies territory switching can occur frequently in an expanding population. However, we found evidence of it in only two of the 46 studied territories, thus we assume that despite the ongoing saturation some level of site fidelity is present in the population. Our findings suggest the high prevalence of mortality, most likely from poisoning and electrocution, but also predict a large number of floater individuals that fill up the vacant territories.

Cím:	Mitochondrial DNA diversity of the Alpine Newt (Ichthyosaura alpestris) in the Carpathian Basin: Evidence for multiple cryptic lineages associated with Pleistocene refugia. / Judit Vörös, Zoltán Varga, Iñigo Martínez-Solano, Krisztián Szabó
Dátum:	2021
ISSN:	1217-8837
Megjegyzések:	The phylogeography and molecular taxonomy of the Alpine newt, Ichthyosaura alpestris, has been intensively studied in the past. However, previous studies did not include a comprehensive sampling from the Carpathian Basin, possibly a key region in the evolution of the species. We used a 1422 bp long fragment of the mitochondrial genome to infer the species` evolutionary history in central-eastern Europe by assigning isolated Carpathian Basin populations from 6 regions to previously defined mtDNA lineages. We also revised the morphology-based intraspecific taxonomy of the species in the light of new genetic data. Alpine newt populations from the Carpathian Basin represented two different mitochondrial lineages. The Mátra, Bükk and Zemplén Mts populations can be assigned to the Western lineage of the nominotypical subspecies. Bakony and Őrség populations showed high haplotype diversity and formed a separate clade within the Western lineage, suggesting that the Carpathian Basin might have provided cryptic refugia for Alpine newt populations in their cold-continental forest-steppe landscapes during the younger Pleistocene. Newts from Apuseni Mts were related to the Eastern lineage but formed a distinct clade within this lineage. Considering the morphological and genetic differentiation of the Bakony and Őrség populations, consistent with a long independent evolutionary history, we propose these populations be referred to as Ichthyosaura alpestris bakonyiensis (Dely, 1964). We provide a redescription of this poorly known subspecies.
