Abstract In the Adriatic, the importance in tourism of the small rowing and sailing boats, like the gajeta and other heritage vessels, is clearly relevant, as icons of heritage boats adorn brochures, logos, and their names are bequested to hotels and restaurants. As a symbol, the gajeta stands for the heritage of the island, and the ethics of the place; these constitute an intangible treasure …

Abstract : This paper explores a socio-economic impact of ferry provision in Zadar island archipelago in Croatia. Poor frequency, accessibility, and unaffordable ferry prices to smaller islands have had a detrimental impact on island communities’ sustainability. This prompts for asking what constitutes the socio-economic impact of ferry provision on remote and rural islands’ sustainability…
Abstract Sustainable management processes have undergone a shift from a top-down approach to a bottom-up approach. This bottom-up approach allows for a more apprehensive inclusion of stakeholders. In traditional hierarchical societies a combination of both is considered more desirable. This combination is described as a participatory approach that allows for bi-directional knowledge sharing. Th…

Despite many negative impacts, these changes also bring opportunities to initiate and implement innovations. Island communities are experiencing the forefront of much such action, particularly since they are often highly local and loca…
Everyone is becoming more environmentally conscious and therefore, chemical processes are being developed with their environmental burden in mind. Of course, this also means that more traditional chemical methods are being replaced with new innovations. This includes new solvents. Solvents are everywhere, but should they be? They are used in most areas including synthetic chemistry, anal…

Expression of stress-related genes was investigated in the marine copepod Acartia tonsa in relation to heatshock at two different salinities (10 and 32‰), and it was furthermore investigated whether experimen-tally induced epibiont infestation led to elevated expression of stress-related genes. Expression of thegenes ferritin, Hsp90 and Hsp70 were analyzed in adult copepods by conducting reve…
tTraditionally, over the last 10,000 years, agriculture has relied on natural biological evolution and carefulselection of plant varieties by farmers that was used as the founder material by plant breeders in the last150 years for further genetic improvement. Plant breeders played an important role mainly by introgres-sion of a trait of interest, through the transfer of genetic loci, into an el…
Understanding gene regulatory networks in plants requires knowledge of cis-regulatory DNA, trans-actingfactors, and their dynamics across development and in response to stimuli. Active cis-regulatory elementsare hypersensitive to cleavage by the endonuclease DNase I. Motifs within DNase I hypersensitive sitesindicate potential trans-acting factor occupancy and, when combined with DNase I cleava…

Plant speciation and diversification strongly rely on structural changes in the nuclear genome, both at the whole ploidy and individual chromosome level. Phylogenetic, comparative mapping and cytological studies have provided insights into the evolutionary mechanisms that shape the plant genome. These include major genome alterations, such as whole genome duplication and hybridization (auto- an…
Retrotransposons are major components of higher plant genomes, and long terminal repeat (LTR) retro-transposons are especially predominant. Thus, numerous LTR retrotransposon families with high copynumbers exist in most plant genomes. As the integrated copies of these retrotransposons are geneticallyinherited, their insertion polymorphisms among crop cultivars have been used as functional molec…
