1. Vzorčenje bentoških nevretenčarjev v rekah brez vpliva kraškega izvira Evdinarske subhidroekoregije za pripravo metodologije vrednotenja ekološkega stanja : končno poročiloMojca Hrovat, Gorazd Urbanič, Maja Sever, Špela Ambrožič Ergaver, Barbara Debeljak, Mihael Jožef Toman, 2012, final research report Abstract: Direktiva 2000/60/ES določa okvir za delovanje Skupnosti na področju vodne politike in upravljanja z vodami. Namen Vodne direktive je preprečevanje nadaljnjega slabšanja stanja vodnih ekosistemov ter varstvo in izboljšanje vodnega okolja. Dobro ekološko stanje površinskih vodnih teles naj bi članice dosegle do konca leta 2015. Bentoški nevretenčarji so eden izmed bioloških elementov, ki so vključeni v sistem razvrščanja vodnih teles rek in jezer po ekološkem stanju. Kot podpora biološkim elementom so v sistem razvrščanja vključeni še podporni hidromorfološki elementi ter kemijski in fizikalno-kemijski elementi. Pridobitev ustreznih podatkov o bioloških in podpornih elementih je prvi korak za pripravo ustrezne metodologije vrednotenja ekološkega stanja voda v skladu z Vodno direktivo (Direktiva 2000/60/ES).
V poročilu “Vzorčenje bentoških nevretenčarjev v rekah brez vpliva kraškega izvira Evdinarske subhidroekoregije za pripravo metodologije vrednotenja ekološkega stanja” so predstavljeni rezultati v skladu s pogodbo št. 38-864/12. Terenske, laboratorijske in kabinetne obdelave ter meritve so bile opravljene v skladu z Uredbo o stanju površinskih voda (Uradni list št. 14, 2009) in Pravilniku o monitoringu stanja površinskih voda (Uradni list št. 10, 2009). V poročilu so zbrani vsi izpolnjeni delovni protokoli za opis mest vzorčenja za vse vzorčene reke. Prav tako so zbrani podatki o merjenih fizikalno-kemijskih parametrih in številčnosti najdenih taksonov. Slike vzorčnih mest so le na priloženem CD-ju.

2. Določanje dobrega okoljskega stanja. Poročilo za člen 9 Okvirne direktive o morski strategiji : zaključno poročilo 2012Martina Orlando-Bonaca, Lovrenc Lipej, Alenka Malej, Janja Francé, Branko Čermelj, Oliver Bajt, Nives Kovač, Borut Mavrič, Valentina Turk, Patricija Mozetič, Andreja Ramšak, Tjaša Kogovšek, Milijan Šiško, Vesna Flander-Putrle, Mateja Grego, Tinkara Tinta, Boris Petelin, Martin Vodopivec, Maja Jeromel, Urška Martinčič, Vlado Malačič, final research report Abstract: Deskriptor 1: Biotska raznovrstnost se ohranja. Kakovost in prisotnost habitatov ter razporeditev in številčnost vrst so v skladu s prevladujočimi fiziografskimi, geografskimi in podnebnimi pogoji.
»Presojo je treba opraviti na več ekoloških ravneh: na ravni ekosistemov, habitatov (vključno z njimi povezanimi združbami na nivoju biotopov) in vrst, ki so upoštevane v strukturi tega dela ob upoštevanju točke 2 dela A. Za nekatere vidike tega deskriptorja je potrebna dodatna znanstvena in tehnična podpora. Pri obravnavi širšega obsega deskriptorja je treba ob upoštevanju Priloge III k Direktivi 2008/56/ES določiti prioritete med elementi biotske raznovrstnosti (vrste, habitati in ekosistemi). To omogoča prepoznavanje tistih elementov in območij, kjer vplivi in grožnje nastajajo, poleg tega pa podpira opredelitev ustreznih kazalcev med izbranimi merili, primernimi za zadevna območja in elemente biotske raznovrstnosti. Obveznost regionalnega sodelovanja iz členov 5 in 6 Direktive 2008/56/ES je neposredno povezana z izbiro elementov biotske raznovrstnosti znotraj regij, podregij in pododdelkov, kjer je mogoče, pa tudi z vzpostavitvijo referenčnih razmer v skladu s Prilogo IV k Direktivi 2008/56/ES. Modeliranje z uporabo platforme geografskega informacijskega sistema je lahko uporabna podlaga za določanje območja razširjenosti elementov biotske raznovrstnosti ter človekovih dejavnosti in pritiskov zaradi teh dejavnosti, ob upoštevanju, da se vse mogoče zajete napake ustrezno ocenijo in opišejo ob uporabi rezultatov. Ti podatki so pogoj za ekosistemsko upravljanje človekovih dejavnosti in za razvoj s tem povezanih prostorskih orodij.«

3. Preiskave kakovosti vode ribnika Tivoli in Koseškega bajerja : končno poročiloMateja Germ, Urška Kuhar, Alenka Gaberščik, Tina Eleršek, Gorazd Urbanič, Gorazd Kosi, Majda Ivanušič, Dušan Fortuna, Mojca Hrovat, Maja Pavlin Urbanič, Barbara Debeljak, final research report Abstract: Vodna telesa, kot sta Tivolski ribnik in Koseški bajer, so pomembni elementi mest. Kot antropogeni tvorbi sta pomembna tako z vidika naravne kot tudi kulturne dediščine. Raziskave so pokazale, da predstavljajo ribniki v spremenjeni krajini, kjer so vodotoki večinoma regulirani in naravni obrežni pasovi okrnjeni ali celo odstranjeni, habitate in zatočišča za različne ptice in žuželke. To je posebej pomembno v mestih, kjer je biotska pestrost zaradi človekovih posegov močno zmanjšana. Z vidika ekosistemskih storitev imajo ribniki pomembno socialno vlogo, saj njihova okolica predstavlja mesto za sprostitev, sama vodna telesa pa lahko služijo tudi v izobraževalne namene. Njihova vloga je tudi podporna, saj uravnavajo okoljske razmere (blažijo temperaturna nihanja in povečujejo vlažnost zraka) na območju. Zaradi intezivnih bioloških procesov se različne snovi, ki prihajajo v ribnike s spiranjem in pritoki, tam razgradijo ali spremenijo. Vse vloge pa so povezane z celovitostjo življenjske združbe in uravnoteženostjo procesov v ribnikih, saj je znano, da je lahko ekološki potencial siromašnih evtrofnih sistemov močno zmanjšan.
Za oceno učinkov v letu 2011 izvedene sanacije ribnika Tivoli ter ovrednotenje stanja Koseškega bajerja smo v letih 2012 in 2013 v skladu s projektno nalogo Preiskave kakovosti vode ribnika Tivoli in Koseškega bajerja opravili preiskave obeh ribnikov. Izvedli smo vzorčenje fitoplanktona, bentoških nevretenčarjev, fitobentosa in makrofitov ter opravili meritve in vzorčenje vode za fizikalno-kemijske analize. V končnem poročilu so zbrani rezultati analiz, ocenjeno je stanje obeh vodnih teles ter predlagani ukrepi za izboljšanje stanja. Ker metodologija za izdelavo ocene ekološkega potenciala še ni pripravljena, smo vodni telesi uvrstili v trofične kategorije. Izjema je le vrednotenje na osnovi bentoških nevretenčarjev.

4. Pigment analysis of Roman wall paintings from two villae rusticae in SloveniaMaja Gutman, Katharina Zanier, Judita Lux, Sabina Dolenec, 2016, original scientific article Abstract: The study deals with the characterisation of paint layers from the wall paintings that decorated two excavated Roman villae rusticae in Slovenia. The villa in Mošnje, located in the NW of Slovenia, was built in the 1st half of the 1st century AD and was in use until the end of the 2nd century AD, while the coastal villa in Školarice, built in the second quarter of the 1st century AD, remained in use until the mid-5th century. Stratigraphy and painting techniques were studied using optical microscopy, with pigments identified via Raman microspectroscopy supported by FTIR microspectroscopy and SEM/EDS. The results of this analysis revealed that whereas the Školarice wall paintings were mainly executed using the fresco technique and some areas with the secco technique, both techniques were identified equally in the Mošnje paintings. Red ochre, lime white and carbon black pigments were identified in both the Mošnje and Školarice paintings, although the latter were also characterised by the use of yellow ochre and green earth.

8. Report on economic justification of the project : LIFE Stop CyanoBloomMaja Zupančič Justin, Gorazd Lakovič, Tinkara Rozina, Bojan Sedmak, Marko Gerl, 2017, final research report Abstract: The Annexe 17 of the Final Report of the project LIFE Stop CyanoBloom, presenting the “Report on economic justification of the project” is composed of 14 chapters. The first part of the report gives a general overview of the cyanobacteria and their blooms, and species and toxicity of cyanobacterial toxins. With a literature review, economic consequences of cyanobacterial blooms on human health, commercial fishery, tourism and recreation, and lake monitoring and management have been evaluated. The chapter on phytoplankton and bacterioplankton monitoring options presents the importance of the phytoplankton for the lake ecology and evaluation of the water quality status. Traditional phytoplankton monitoring approaches are compared to the new monitoring options applied in the project. The chapter in-lake cyanobacterial control options give a broad review of available in-lake rehabilitation and remediation options, which can be compared with the electrochemical oxidation technique presented in the following chapter and applied in the project. According to the results obtained during the pilot testing activities, a cost evaluation of the approach has been performed and presented in the report. The last chapter gathers open issues and proposals for the further work in this field.

9. Innovative technology for cyanobacterial bloom control : LIFE Stop CyanoBloomMaja Zupančič Justin, Marko Gerl, Gorazd Lakovič, Bojan Sedmak, Tinkara Rozina, Neža Finžgar, Maja Čič, Mario Marinovič, Luka Teslić, Jošt Grum, Maša Čater, Tina Eleršek, Andrej Meglič, Andrey Yakuntsov, Lovro Pokorn, Tomaž Kralj, Matjaž Berčon, Branko Hamiti, 2017, final research report Abstract: Despite the efforts invested into measures to prevent water eutrophication, like prevention and treatment of point and dispersed discharges, the eutrophication still occurs. One of the unwanted consequences of eutrophic water state is the occurrence of excessive cyanobacterial blooms. Mass occurrence of cyanobacteria is a significant health risk related to surface waters in EU and worldwide since most of the cyanobacterial genera produce cyanotoxins. Besides toxicity, cyanobacterial blooms cause an increase in the turbidity of water and create taste and odour problems. All mentioned represents substantial economic losses in sectors like aquaculture, tourism, drinking water facilities and indirect losses due to increased healthcare expenditures and environmental degradation. It is, therefore, necessary to find appropriate solutions for rapid detection and also in-lake prevention of bloom occurrence despite, for example, existing high eutrophic conditions in the water body. The proposed project represents such a solution.
In the frame of the LIFE Stop CyanoBloom project, we have designed two solar powered robotic vessels for the in-lake detection and control of cyanobacterial proliferation. Each vessel is capable of three-dimensional localisation of cyanobacteria by measuring fluorescence of pigments involved in the process of photosynthesis. The vessels are additionally equipped with electrochemical cells using boron doped diamond electrodes fixed on board, producing short-lived hydroxyl radicals, which prevent cyanobacterial proliferation as well as cyanotoxins inactivation. Hydroxyl radicals cause different levels of damages to cyanobacterial cells as well as stress, that may also result in phage induced cyanobacterial lysis. Natural control of cyanobacterial density by lytic cyanophages is known for several years. The mixing of water during the electrolytic cell operation also increases the potential contacts of cyanobacteria with cyanophages, disturbs cyanobacterial buoyancy and generates additional nutrients for nontoxic phytoplankton population. Additional newly developed equipment of the vessel allows advanced automated navigation (automatic docking, avoiding obstacles, maintaining the position in windy conditions, etc.), sampling from different depths, real-time data transfer, statistical analysis and graphical presentation using the adequate software.
