162. Genomic diversity and population structure of Carniolan honey bee in its native habitatBoris Lukić, Nikola Raguž, Marin Kovačić, Ino Čurik, Jana Obšteter, Janez Prešern, Jernej Bubnič, Ras Lužaić, Ivan Pihler, Goran Mirjanić, Marco Pietropaoli, Zlatko Puškadija, 2024, original scientific article Abstract: Background Research into the genetic diversity of honey bee (Apis mellifera L.) populations has become increasingly signifcant in recent decades, primarily due to population declines attributed to human activities and climate change. As a species of great importance, breeding programs that leverage understanding of genomic diversity could ofer solutions to mitigate these challenges. The objective of this study was to examine the genomic diversity and population structure of Carniolan honey bees (Apis mellifera carnica) using the Illumina SNP chip on a large honey bee sample collected from Central and South-Eastern European countries. The study also aims to ofer recommendations for future breeding programs

164. Forest beetles associated with cork oak and fomes fomentarius fungi in the Collo massif (Skikda), AlgeriaFaiza Marniche, Gahdab Chakali, Sabrina Laouira, 2024, original scientific article Abstract: A study conducted in an unburned cork oak forest located in the Collo Massif (Skikda), northwestern Algeria, resulted in the capture of 385 beetles in 2015 and 545 beetles in 2016 at three sub-stations, using Barber pitfall traps. The study lasted three months, from April to June, over two consecutive years. Additionally, using the carpophores method on Fomes fomentarius (Linné) (Fries, 1849), a total of 3,017 beetle specimens were obtained in 2015 and 3,107 beetle specimens in 2016, observed over the same three-month period around the three unburned sub-stations (Oued Agouf, Ain Fegoum and El Maktoua). The first observation concerning the Erotylidae family is that they are poorly known in North Africa, including Algeria, where published data on this subject is scarce. This study also revealed the presence of the species Triplax melanocephala (Latreille, 1804), which is rarely observed in Algeria. This species was recorded on the tinder fungus Formes fomentarius, with 30 individuals and 71 individuals counted in the Barber pitfall traps.

165. Associative organisational models in Italian forests for addressing land abandonmentFrancesco Loreggian, Davide Pettenella, Laura Secco, Nicola Andrighetto, Giorgia Bottaros, 2024, original scientific article Abstract: This paper investigates associative organisational models as a potential governance solution to the issue of land abandonment. Land fragmentation, along with inadequate or absent management, are key problems that hinder forest stability and resilience in many countries, particularly in Southern Europe. Land abandonment further exacerbates these issues, increasing climate change-related risks, such as forest fires. After reviewing the broader European context, the paper focuses on Italy, where this problem is particularly acute. Based on a qualitative content analysis of the literature and policy documents, the paper outlines the available solutions for promoting active forest management through associations, as outlined by Italian forest law. Several types of associative models exist, facilitated by recent policy initiatives, including forest consortia, forest associations and cooperatives, and various instruments for regulating partnerships and associative management. However, limited data on land abandonment and forest ownership, especially regarding private ownership, hampers effective implementation and monitoring, highlighting a significant research gap in this area.
