Article
Full-text available
To explore local adaptation in wild populations at a fine spatial scale we characterized the genetic variability of eight closely located populations of Drosophila subobscura and its associations with microhabitat environmental conditions. Three different genetic markers were assessed: chromosomal inversions, a SNP of mitochondrial ND5 gene and nuc...
Article
Full-text available
Mitochondrial DNA variability of Drosophila subobscura Collin from Southeastern Serbia was studied with respect to Restriction Site Analysis (RSA) of complete mitochondrial genome and the nucleotide sequence of Cytochrome b (Cyt b) gene. The aim was to shed more light on the evolutionary forces that shape mtDNA variation of this species. Samples we...
Article
Ecological and evolutionary factors, together with abiotic conditions, affect biogeographic patterns of genetic entities. The spatial and temporal variability of chromosomal inversions of Drosophila subobscura suggests that this species can serve as a good model for studying the effects of environmental change on the genetic structure of natural po...

Growing anthropogenic influence on every aspect of environment arise important issues regarding the ability of populations and species to adapt to variant pressures. Lead is one of the most present contaminants in the environment with detrimental influence on organisms and populations. In combination with genomic stress, lead may act synergisticall...
Article
Full-text available
Lead is one of the most present contaminants in the environment, and different species respond differently to this type of pollution. If combined with genomic stress, lead may act synergistically, causing significant decrease of fitness components. We used two genetically diverse Drosophila subobscura populations (regarding both putatively adaptive...

Over the past century, man-made electromagnetic fields (EMF) have changed the natural environment, representing one of the most common and rapidly increasing environmental factors as technology advances. Numerous studies of biological effects of exposure to EMF have been performed on Drosophila during the last 30 years, showing contrasting results....
Article
Full-text available
A number of recent studies have shown that the pattern of mitochondrial DNA variation and evolution is at odds with a neutral equilibrium model. Theory has suggested that selection on mitonuclear genotypes can act to maintain stable mitonuclear polymorphism within populations. However, this effect largely relies upon selection being either sex-spec...
Article
Full-text available
Local adaptation to environmental stress at different levels of genetic polymorphism in various plants and animals has been documented through evolution of heavy metal tolerance. We used samples of Drosophila subobscura populations from two differently polluted environments to analyze the change of chromosomal inversion polymorphism as genetic mark...
Article
Full-text available
Contamination represents environmental stress that can affect genetic variability of populations, thus influencing the evolutionary processes. In this study, we evaluate the relationship between heavy metal contamination (Pb) and phenotypic variation, assessed by coefficients of variation (CV) of life-history traits. To investigate the consequences...
Article
Abstract Differences in heavy metal tolerance among separate populations of the same species have often been interpreted as local adaptation. Persistence of differences after removing the stressor indicates that mechanisms responsible for the increased tolerance were genetically determined. Drosophila subobscura Collin (Diptera: Drosophilidae) popu...
Article
Full-text available
The aim of the current study was to analyze the direction and range of changes in wing size and shape in both sexes of Drosophila subobscura (Collin, 1936) species that originated from two natural populations with different evolutionary history (sampled from ecologically distinct habitats) maintained during seven generations in laboratory condition...

Jelic M., B. Kenig, M. Tanaskovic, M. Stamenkovic-Radak, and M. Andjelkovic (2012): Relationship between chromosomal and mitochondrial DNA variability of Drosophila subobscura population from the Lazar's river canyon. - Genetika, Vol 44, No. 2, 409 -417. The genetic structure of Drosophila subobscura population from the Lazar's River Canyon (Serbia...
Article

The genetic structure of Drosophila subobscura from the Balkan Peninsula was studied with respect to restriction site polymorphism of mitochondrial DNA in populations from the Derventa River Gorge and Sicevo Gorge (Serbia). To investigate the role of cytonuclear interactions in shaping mitochondrial DNA variability in natural populations of this sp...
Article
Full-text available
Background: The Balkan Peninsula was one of three main refugia for many European species during the last glaciation. During that period, glacial–interglacial climate oscillations probably shaped the habitat characteristics and influenced the population genetic structures of the Balkan species we see today, including Drosophila subobscura. Hypothesi...

Full-text available
Fauna of Drosophilidae in Serbia has been studied for 40 years. This paper presents the results of faunistic research conducted on Mt. Goč in June 2011 in two forests (beech and oak), which are significantly different in the type of vegetation and microclimatic factors. In the oak forest eight species of Drosophila were registered, while in the bee...

Fluctuating asymmetry (FA), the increased variation of bilateral symmetry in a sample of individuals, can indicate disturbance in developmental stability caused by environmental and/or genomic stress. This developmental instability was analyzed in Drosophila subobscura maintained for seven generations on two different concentrations of lead in labo...
Article
Full-text available
Populations of Drosophila subobscura from the urban area of Belgrade and from the locality, Deliblato, which is not under strong anthropogenic influence, were studied with the aim to characterize and compare their genetic structure by examining chromosomal inversion polymorphism. Additional analysis and comparison of this type of polymorphism with...
Article
Full-text available
Adaptation to different environmental conditions is a natural phenomenon that potentially leads to population subdivision. We surveyed genetic differentiation in inversion polymorphism within populations of Drosophila subobscura sampled in three ecologically different forest communities. The analysis of inversion polymorphism revealed significant d...
Article
Full-text available
We analyzed changes in the genetic structure of two ecologically distinct populations of Drosophila subobscura by assessing inversion polymorphism parameters for over years. The frequencies of gene arrangements on all five chromosomes show variability in each population. Several chromosomal arrangements appeared for the first time in both populatio...

The research within the project OI173012 refers to population-genetic processes as a basis of micro-evolutionary changes, with its fundamental aspect within population and conservation biology, and applicability in fields of biodiversity protection and conservation. It covers studies of integrated population response in spatial and time environmental changes, environmental and genomic stress from the aspect of genetic and phenotypic variability. Considering the relationship of the genetic diversity and evolutionary potential of populations, the data obtained for genetic and phenotypic diversity will provide insight of potential of the populations to respond to environmental changes. One aspect includes research and monitoring of genetic structure of natural populations of Drosophila, as well as adaptive response of laboratory populations, which both allows understanding of mechanisms and adaptive potential of variability. Results allow extrapolation to natural populations which cannot be experimentally reared. Also, the research covers monitoring of phenotypic and genetic variability of Syrphidae and Culicidae from wider region of Europe, with the goal of elucidating evolutionary potential of space and time fragmented species. The research allows understanding of the environmental and genomic interactions, as well as processes and adaptation to climate change, pollution, habitat fragmentation. They have fundamental aspect in population biology, and application value in biodiversity conservation and maintenance.
