1. Nest survival of great tit Parus major in spatial and temporal gradientDejan Bordjan, Davorin Tome, 2013, izvirni znanstveni članek Povzetek: 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.

4. Protection study for Ulcinj Salina : final versionAndrej Sovinc, Davorin Tome, Michael Hošek, 2017, končno poročilo o rezultatih raziskav Povzetek: 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.

5. 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, končno poročilo o rezultatih raziskav Povzetek: 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. Kmetijstvo in biodiverziteta z roko v rokiMojca Pibernik, Blaž Koderman, Danilo Bevk, Aleš Tolar, Janko Rode, 2019, druge monografije in druga zaključena dela Povzetek: 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.

10. Akcijski načrt za Krajinski park Ljubljansko barje : 28. marec 2019, LjubljanaAl Vrezec, Davorin Tome, Nataša Mori, Andrej Kapla, druge monografije in druga zaključena dela Povzetek: ACTION PLAN for improved policy instrument »Regulation on Ljubljana Marsh Nature Park" was developed within the European Interreg Europe project "From biodiversity data to decisions" (BID-REX), which deals with the problem of biodiversity data use in decision-making processes. BID-REX aims to encourage the use of relevant information on biodiversity in order to more efficiently use the resources of the European Regional Development Fund (ERDF) to conserve the European natural heritage.
The project includes 9 partners and 7 different policy instruments from six European countries: Spain, Great Britain, Italy, Belgium, Hungary and Slovenia. In Slovenia, testing instrument is the Regulation on Ljubljana Marsh Nature Park". The project is divided into two phases. During the preparatory phase, which lasted from April 2016 to the end of March 2019, partners developed action plans to improve selected policy instruments. A support for Action plan development was exchange of good practices between BID-REX partners and interregional learning process that was carried out during five thematic workshops each organized by one BID-REX partner. In the next phase, ending in March 2021, the implementation of Action plans will follow.
In the pilot region the Ljubljana Marsh Nature Park, we identified that biodiversity data are scattered among various experts and organizations, and are often difficult to access for nature conservation purposes. The Institute of the Republic of Slovenia for Nature conservation, which is the central governmental organization for nature conservation, has access to limited amount of data that relate exclusively to Natura 2000 species and habitats.
The purpose of Action Plan is (i) to link experts and organizations collecting data on species in the area of Ljubljana Marsh, e.g., to build knowledge network, (ii) to collate all available biodiversity information for Ljubljana Marsh, (iii) to provide on-line access to biodiversity information, (iv) to identify and prioritize species that are important for this area, and lastly, (v) to propose conservation measures that will protect priority species.
