1992. Managing invasive alien species in forest corridors and stepping stonesGiuseppe Brundu, Maarten De Groot, Sabrina Kumschick, Jan Pergl, Katharina Lapin, 2025, independent scientific component part or a chapter in a monograph Abstract: Invasive alien species (IAS) pose a signiicant threat to forest ecosystems by disrupting ecological networks and competing with native species. Forest habitat patches and corridors designed to enhance connectivity and biodiversity can unintentionally promote the dispersal of IAS, further compromising the ecological integrity of the forest ecosystem. This chapter discusses two main aspects related to IAS and forest connectivity: (1) the spread of IAS in the landscape and their impacts on native species and (2) the consequences of IAS on forest connectivity. Effective management of IAS is crucial to improve connectivity for native species while restricting the spread opportunity for aliens and preserve biodiversity. Ideally, a site-speciic risk analysis should precede conservation or restoration efforts, determining the potential impact of IAS on the respective habitat patch’s structural and functional connectivity, and vice versa. Furthermore, this chapter explores management strategies to control IAS, including physical removal, biological control, and monitoring. Citizen involvement and remote sensing play vital roles in supporting management actions, IAS detection and long-term monitoring, and habitat connectivity. Including stakeholders such as forest owners and managers in such actions ensures a collaborative approach to safeguarding forest ecosystems from the threats posed by IAS.

1993. Managing forest health in connected landscapesGernot Hoch, Katharina Lapin, Maarten De Groot, 2025, independent scientific component part or a chapter in a monograph Abstract: Managing forest health is a critical challenge for forest managers and policymakers worldwide, especially in connected forests where ecological and socio-economic linkages are tightly intertwined. Conservation and sustainable management of forest ecosystems require the development and implementation of comprehensive strategies that address the complex interactions between natural and human-driven stressors affecting forest health. In this chapter, we review the main drivers of forest health degradation and provide an overview of the approaches and tools that can be used to monitor and manage forest health. We highlight the importance of integrating practical knowledge with scientific information to enhance the resilience of forest ecosystems to global environmental changes. Finally, we discuss the challenges and opportunities associated with managing forest health in connected forest landscapes, and we suggest possible strategies to improve forest health management.

1996. Faunistic, ecological, and zoogeographical survey of heterobranch fauna in the Adriatic Sea: experiences from SloveniaLovrenc Lipej, Ana Fortič, Domen Trkov, Borut Mavrič, Danijel Ivajnšič, 2025, original scientific article Abstract: The heterobranch fauna recorded to date in the Slovenian part of the Adriatic Sea was reviewed and analysed in order to present an updated inventory. The ecological traits and zoogeographical affiliation of the recorded heterobranchs were also analysed. The new data revealed that the heterobranch fauna in the area consists of at least 157 species with the majority being nudibranchs (61.4%). The bulk of heterobranchs were considered as Atlanto-Mediterraneans. Heterobranch diversity was found to be significantly related to the number of sampling events. The spatial pattern of heterobranch species and their composition structure in parts of the study area were linked to specific human-impacted areas (HIAs) such as coastal wetlands, ports, and mariculture facilities. Better examination of less investigated environments, new sampling techniques, and citizen science involvement will doubtlessly increase the numbers in this checklist.

1998. The microstructure of scales varies in four lizard speciesAnamarija Žagar, Katja Konc, Matej Hočevar, Urban Dajčman, Valentina Perc, Rodrigo Megía-Palma, Miguel A. Carretero, Damjana Drobne, Sara Novak, 2025, original scientific article Abstract: The microstructure of lizard scales carries a phylogenetic signal in traits, reflecting key adaptations with high functional value. Using scanning electron microscopy, we examined the skin surface of four European Lacertidae species which occur in different habitats, as well as climatic conditions. We sampled Podarcis carbonelli and P. virescens from an oceanic-influenced climate, Zootoca vivipara from a temperate climate, and Gallotia galloti from three climatically distinct sites. In all species, dorsal midbody scales were proximally laminated. However, G. galloti differed from the other species, displaying spiny margins on lamellae, whereas Podarcis species and Z. vivipara had smooth margins. Within G. galloti, spiny microstructures were denser and larger in the northern, humid population compared to the high-elevation and southern, drier populations. These differences highlight the potential functional role of microstructures in skin adaptation to environmental conditions and emphasize their ecological significance in lizard species across climatic variation.
