2. Nest survival of great tit Parus major in spatial and temporal gradientDejan Bordjan, Davorin Tome, 2013, original scientific article Abstract: The aim of the study was to compare nest survival of Great Tit between different regions, altitudes and years to discern which has the highest influence. Temperature is known to be prominent for breeding parameters and it changes consistently with altitude. Our hypothesis was that altitude has greater influence on nest survival than the region and year. Breeding parameters were monitored with the use of nestboxes over a three year period at three altitude belts in two regions. The main factor influencing nesting success was modelled using daily survival rate in the program MARK. We gathered data from 104 first nesting attempts of which 26 failed. Although nest failure increased with altitude this was significant only for one region. There was significant difference in nest failure between the regions but not between the years. Modelling showed higher support in data for regions than for altitudes and years thus rejecting the hypothesis. Some possible reasons for such results are discussed.

5. Protection study for Ulcinj Salina : final versionAndrej Sovinc, Davorin Tome, Michael Hošek, 2017, final research report Abstract: Ulcinj salina is situated in the outermost southern part of Montenegro and covers slightly less than 14.5 km2 of salty basins (total surface area is 1.477 ha). The salina is 1 km from the city of Ulcinj and from the Albanian border.
Ulcinj salina is located on the site of the former lagoon and wetland in the delta of the River Bojana. The works on amelioration of the former wetland area started in 1913. That is when the wetland was connected with the sea by the Port Milena channel and isolated itself from the Bojana River with a dike. In 1920 the decision to start with the establishment of the salina in Ulcinj was made. The salina was concluded in 1934 and the first harvesting of salt was done in 1935. The Ulcinj salina was created from the sea and represents a "cultural lagoon" and a man-made landscape. It is surrounded by channels that drain the nearby marshes and “knetas” (adjoining marshlands), not allowing their water to mix with the water from the salina. The channels take the water into the Port Milena canal and then into the sea.
The technological process of production was upgraded in the 1970s with construction of the refinery and with attempts to expand the production, both by enlarging the territory of the salina and use of industrial production between 1984 and 1994. Yearly production of salt before the above-mentioned attempts to expand the production (in the period 1935 to 1983) was highly dependent on the weather conditions and organisation of work; a maximum of 41.240 tons of salt was produced in 1952. A combination of manually collected salt and the salt produced through industrial process in the newly constructed factory in the years 1984 to 1994 led to a maximum yearly production of 59.353 tons. By contrast, the production in the last years of production (2003 to 2013) was dramatically lower, reaching on average only around 17.000 tons per year.
Ulcinj salina has very hot summers, moderately warm autumns and springs, and mild winters with temperatures only rarely below zero. On average, the most rain falls in autumn and winter, summers are two to three times more dry. Year-on-year and within years, changes in the amount of rain can be significant. Powerful pumps are essential for assuring constant water levels in basins which supports the maintenance of the ecological character of the area. The absence of salt production and consequent changes in water management have caused changes in water salinity, water regime and consequently changes in biodiversity.

6. Better data, better decisions : increasing the impact of biodiversity informationMatthew Ling, Luc Derochette, Marta Iturribarria, Martin Horlock, Zoltan Karacsonyi, Nataša Mori, Goizalde Atxutegi, Gotzon Bernaola, Gerard Bota, Lluís Brotons, Alessandro Cartuccia, Pilar Casanovas, Paul M. Dolman, Lorenzo Federiconi, Melanie Gillings, Núria Pou, Marta Rozas, Pau Sainz de la Maza, Annick Terneus, Davorin Tome, Dani Villero, Al Vrezec, Claudio Zabaglia, 2019, final research report Abstract: Without understanding something it is impossible to effectively manage it. In terms of biodiversity and environmental conservation, data and information on species or habitat extent or range, populations, trends over time, and the pressures and threats to these are essential to such understanding and management. Decision makers are wholly reliant on accessing or being presented with this data and information, and using their knowledge and experience to make reasoned, rational, and objective choices.
Whilst various gaps remain, great quantities of data and information are available, covering many facets of life and our environment. Yet many challenges and barriers exist that prevent the effective flow of this data from those that collect and manage it, to those that need to call upon it to inform decision-making processes. These can be as simple as a lack of communication or understanding of where to find or submit the data, to format issues whereby the necessary infrastructure isn’t in place or suitable to support the system, or more complex issues including data gaps, or scepticism in the data itself, leading to its lack of use.
The importance of data is recognised in various global conventions and European processes (e.g. Convention on Biological Diversity’s Aichi Biodiversity Targets, and the EU Biodiversity Strategy), acknowledging its role in developing our understanding of, and ability to monitor, manage, and ultimately halt, biodiversity loss.
Despite the multitude of data and information that exist, and the political and legislative measures in place, biodiversity continues to be threatened and is in various stages of decline. Many conservation and sustainability targets and goals are not on track to be achieved. The inefficient flow of data to inform decision-making processes contributes to this situation, by creating uncertainty about situations on the ground and the ability to track progress.
The Interreg Europe project ‘From biodiversity data to decisions: enhancing natural value through improved regional development policies’ – BID-REX – aims to bridge the gap between biodiversity data and decision-making, linking the two to create improved regional development policies for the preservation of nature.
By demonstrating how the use of available, evidence-based biodiversity data can guide, benefit, and improve decision-making processes, BID-REX also seeks to promote budget prioritisation for conservation efforts in funding allocations.

8. Moja, tvoja, naša biodiverzitetaDanilo Bevk, Marjana Hönigsfeld Adamič, 2019, other monographs and other completed works Abstract: Radi imamo dišeč, pisan travnik. Radi imamo jutranjo pesem ptic. Radi imamo žuboreč potok in kačjega pastirja nad njim. Radi imamo…
Zakaj ne bi torej imeli radi biodiverzitete, ki nam vse to omogoča? Zbližajmo se z njo, spoznajmo njene čare! Kajti tisto, kar nam je blizu in kar poznamo, veliko lažje varujemo.

9. Kmetijstvo in biodiverziteta z roko v rokiMojca Pibernik, Blaž Koderman, Danilo Bevk, Aleš Tolar, Janko Rode, 2019, other monographs and other completed works Abstract: Biodiverziteta je vse živo
Biodiverziteta (biotska pestrost) je pestrost življenja na Zemlji od bakterij in gliv do rastlin in živali. Nastala je v milijardah let razvoja življenja. Pomembna značilnost biodiverzitete je izjemna povezanost organizmov, ki sami ne bi mogli preživeti, skupaj pa sestavljajo edinstven preplet, ki odločilno vpliva na razmere na našem planetu.
