AN APPROACH TO THE DEVELOPMENT OF THE URBAN DESIGN “KARAOTOK”, HUTOVO BLATO NATURE PARK

Prostorno planiranje je vitalni proces za brzo i uspješno razvijanje projekata vezanih za upravljanje vlažnim staništima, time i projektima vezanim za turizam. Turističke aktivnosti mogu dati obol razvijanju općeg razumijevanja, te podizanju pozornosti javnosti za vlažna staništa i njihove funkcije i ekološke sustave. Pored toga, turizam može biti i izvor prihoda te može pružiti mogućnosti zapošljavanja u ruralnim sredinama. Turisti također imaju utjecaj na vlažna staništa. Mjesta koja su dostupna turistima traže intenzivnije upravljanje negoli ona koja im nisu pristupačna. U cilju osiguranja skladnog odnosa između turističkih aktivnosti i zaštite okoliša prijeko je potrebno pristupiti procesu izrade urbanističkog projekta u sklopu zaštićenog područja na iznimno senzibilan način. U radu je sugeriran pristup izradi Urbanističkog projekta „Karaotok“, u sklopu Parka prirode Hutovo blato.Spatial planning is a vital process for a rapid and successful development of projects related to wetland management, and thereby projects related to tourism. Tourist activities could provide a boost to the development of general understanding of wetlands and raise public awareness of the functions and the ecosystem services wetlands provide. The tourism economy could be a source of income and could provide employment opportunities in rural areas. However, tourists also have an impact on wetlands. Protected areas accessible to tourists require a comprehensive management. In order to ensure a harmonious relationship between tourism activities and environmental protection, when developing an urban design within a protected area, it is crucial to have a sensitive approach. The paper suggests an approach to the development of the Urban Design "Karaotok", within the Hutovo Blato Nature Park

Biodiversity and seasonal distribution of benthic diatom assemblages as an indicator of water quality of small karstic river in Bosnia and Herzegovina

The aims of this paper were to describe seasonal changes in the qualitative and quantitative composition of diatom taxa and the potential application of benthic diatoms for ecological status evaluation. Diatom indices (IPS and TI) were calculated from data from three different locations along a longitudinal profile of the Bunica, a small karstic river in Bosnia and Herzegovina. A total of 147 taxa were recorded in 12 samples. The most common taxa were Meridion circulare (Greville) C.Agardh and Ulnaria ulna (Nitzsch) Compère. Physical and chemical analyses showed low concentrations of nutrients, good oxygenation, typical pH for carbonate bed/origin and generally oligotrophic conditions and high ecological status. All sites had similar physico-chemical conditions and there were only few seasonal differences. Ordination of the diatom data showed that samples showed neither longitudinal nor seasonal patterns. Median value for IPS (16.8) and for TI (7.3) can be possible ‘‘expected’’ values for ecological status assessment for small karstic rivers in the Mediterranean region. We propose the use of the phytobenthos Intercalibration Common Metric (pICM - an index that combines the IPS and TI) as a national metric for countries developing WFD diatom methods at a late stage. One situation is described, and a solution, which is potentially transferable to other locations in Bosnia and Herzegovina and also to other countries facing similar challenges

Odrasli tulari (Insecta: Trichoptera) kao pokazatelji ekološkog statusa rijeke Lištice, Bosna i Hercegovina

A study of caddisfly biodiversity and its application for use as indicator species to assess the ecological integrity of aquatic environments was conducted in the area of the Lištica River, Bosnia and Herzegovina. A portable UV lighttrap was used to collect caddisflies at two sites: the spring of Lištica - Bilo Vrilo and the middle reach of this river in a karstic depression - Mostarsko Blato. From March 2003 to March 2004 a total of 4334 individuals, representing 34 species, were caught. There were signifi cant differences in species composition and abundance between sampling sites. The flight periods are shown for all recorded species and studied in detail for twelve abundant species. The species inventories were used for analysing the longitudinal classification of the sampling sites, composition of functional feeding guilds and the saprobic indices.Istraživana je bioraznolikost tulara rijeke Lištice te primjena njihovih zajednica u procjeni ekološkog statusa vodenih ekosustava. Odrasle jedinke uzorkovane su na dvjema postajama, tj na izvoru rijeke Bilo vrilo i središnjem dijelu toka Lištice, u krškom polju Mostarskom blatu. Materijal je prikupljan godinu dana (ožujak 2003. – ožujak 2004.) metodom lova pomoću UV lampe. Istraživanjima su zabilježene 34 vrste s 4334 uzorkovanih jedinki. Utvrđene su značajne razlike u fauni tulara na dvjema istraživanim postajama, koje su se ogledale u sastavu zajednica i brojnosti uzorkovanih jedinki. U radu je prikazan period aktivnosti svih zabilježenih vrsta te je analizirana sezonska dinamika dvanaest vrsta s najvećim brojem uzorkovanih jedinki. Na temelju sastava zajednica odraslih tulara određeni su indeksi saprobnosti, rasprostranjenost hranidbenih skupina te longitudinalna klasifi kacija staništa

Izvori: DNA barkodiranje tulara (Insecta, Trichoptera) u Hrvatskoj s napomenama o taksonomiji i konzervacijskoj biologiji

The paper provides the results of DNA barcoding based on the cytochrome c oxidase subunit 1 mitochondrial gene (mtCOI) of 110 Trichoptera specimens collected in 36 springs in the PannonianPeripannonian, central mountainous and Mediterranean part of Croatia. We barcoded 70 species from 32 genera and 15 families. The data obtained show interesting faunistic and taxonomic results, for, for example, the species Rhyacophila cabrankensis, R. balcanica, Crunoecia kempnyi, Allogmaus auricollis and emphasize the need for further faunistic research into springs, in their role as habitats with a specific and very interesting fauna. The mtCOI DNA barcoding should be included in such research, because it would enable better presentation of the results, especially regarding biodiversity, taxonomy, phylogeny and conservation biology, not just as a segment of a local but also of a global process of understanding biodiversity in a different way. The results of this study show a global need for the protection of springs, because they are specific not only as habitats, but also as localities with an interesting fauna and often endemic species of very limited distribution (for example Rhyacophila cabrankensis).U radu se prikazuju rezultati DNA barkodiranja temeljenog na mitohondrijskom genu za podjedinicu 1 citokrom c oksidaze (mtCOI), za 110 primjeraka Trichoptera prikupljenih u 36 izvora u panonsko-peripanonskom, središnje-planinskom i mediteranskom području Hrvatske. DNA barkodirano je 70 vrsta iz 32 roda i 15 porodica. U studiji se ukazuje na neke zanimljive faunističke i taksonomske rezultate, npr. za vrste Rhyacophila cabrankensis, R. balcanica, Crunoecia kempnyi, Allogmaus auricollis te potrebu daljnjih faunističkih istraživanja izvora kao staništa sa specifičnom i vrlo zanimljivom faunom. U ta istraživanja zbog kvalitetnije prezentacije rezultata, posebno u područjima bioraznolikosti, taksonomiji, filogeniji i konzervacijskoj biologiji, potrebno je uključiti i metodu DNA barkodiranja mtCOI, kao segment ne samo lokalnog, nego i globalnog procesa u spoznavanju bioraznolikosti na jedan drugačiji način. Navedeni rezultati ovog rada ukazuju na globalnu potrebu veće zaštite izvora jer su specifični ne samo kao staništa, nego vrlo često i kao područja nalaza endemskih vrsta s vrlo malim područjem rasprostranjenja (npr. Rhyacophila cabrankensis)
