Y-chromosomal STR haplotypes in three ethnic groups and one cosmopolitan population from Tunisia

The 11 Y-chromosomal short tandem repeats (STRs) included in the Promega Corporation PowerPlex Y System (DYS19, DYS389I, DYS389II, DYS390, DYS391, DYS392, DYS393, DYS385, DYS437, DYS438 and DYS439) were typed in three ethnic groups ("Andalusians", Berber and Arab) and one cosmopolitan population (Tunis) from Tunisia, summing up 247 individuals, and 139 different haplotypes. Focusing the analysis on the seven Y-STRs of the YHRD Minimal Haplotype Core (DYS385 excepted), "Andalusians" showed no differences from the Cosmopolitan and the Arab samples previously published (our Arab sample presented an extremely low haplotype diversity), but were different from the Berbers. The Berbers from Tunisia were not different from those from Morocco.     

Importance of Interdisciplinary Spatial Planning of National Parks＂ Case Study of Croatia

With the attempt to ＂reconcile＂ protection and tourism activities, spatial planning has a great importance in sustainable planning and management of Nature Protected Areas （NPAs）. The spatial dimension of sustainability involves numerous processes and links among different purposes of lands, ecosystems, and biotopes at different levels through time, therefore, it is necessary to include all sciences and professions, whose common goal is the sustainability of the area, in the spatial planning process. This paper argues that there is a critical need for an interdisciplinary approach in spatial planning, which could improve the quality of planning of national parks and all other sensitive nature areas. Such approach should strive to the sustainability of protected nature destinations with the integration of knowledge. In Croatia, national park planning is still mostly done without comprehensive and integrated involvement of a wide range of science and profession, which ultimately significantly reduces the quality ＆the plans, as well as may have potentially negative effects on the future development.     

Sequence variation at three X chromosomal short tandem repeats in Caucasian and African populations

Sequence variation for the X chromosome short tandem repeats (X-STRs) DXS9898, DXS6789 and GATA172D05 was studied in two major population groups, namely Caucasians and Africans. DXS6789 revealed two different subtype sequence polymorphisms: for shorter alleles, with less than 17 repeats, results showed a simple composition with the following structure: (TATG)_m-(TATC)_n. For longer alleles, a constant TATC insertion was observed at the beginning of the variable repeat unit. Additionally, alleles identical in size revealed structural variations regarding the TATG/TATC proportion. Africans showed a higher intra-allelic variation at this locus than the Caucasian population group. For all three loci, DXS9898, DXS6789 and GATA172D05, no unique structure was found among Africans and Caucasians.     

The Karimojong from Uganda: Genetic characterization using an X-STR decaplex system

The Karimojong, an African group from the Karamoja region of Northeast Uganda, were genetically analysed using a decaplex system for X chromosome short tandem repeats (X-STRs). A total of 255 individuals (117 males and 138 females) were genotyped for the following loci: DXS8378, DXS9898, DXS7133, GATA31E08, GATA172D05, DXS7423, DXS6809, DXS7132, DXS9902 and DXS6789. Allele frequencies and parameters for forensic evaluation were calculated for each STR. No association was found between any pairs of loci studied. DXS6789 was the most polymorphic marker in this sample, followed by DXS6809, with gene diversities of 84.79% and 83.94%, respectively. The less discriminating locus observed was DXS7133, with a gene diversity of 39.79%. High overall values of power of discrimination were obtained for female (1 in 1.8 × 10¹⁰) and male samples (1 in 1.6 × 10⁶), as well as high power of exclusion in father/mother/daughter trios (99.9997%), in father daughter duos (99.9862%) and in half sisters with same father (99.0331%). These results confirm the potential of this 10-plex in parentage testing and in human identification.     

From “sensed” to “complex”: some reflections on borders throughout history

The concept and definition of borders has evolved significantly over time. In Europe the twentieth century alone has seen remarkable changes. At the beginning of the century borders represented the clear end of the sovereignty of one state and the beginning of another while the second half of the same century brought revolutionary concepts of state borders. This article aims to contribute towards the conceptual discussion of borders, tracing some of the journey of this concept, from centuries ago when they were perceived as more ”sensed”, to more recent interpretations of ”solid” and “liquid” borders to today's “complex” borders.
