The journal Acta Botanica Croatica focuses on various fields ranging from subcellular levels to ecosystems, including both terrestrial and aquatic environments, as well as experimental botany involving microorganisms, plant viruses, bacteria, and unicellular algae. It particularly emphasizes research in the karst regions, karst waters, and the Adriatic Sea (Mediterranean) of Southern Europe.

Stellaria ruderalis (Caryophyllaceae) is an annual herb of the S. media group, recently described in Central Europe and later discovered in other regions of the continent and beyond. Here, we provide novel data on its occurrence in the Caucasus Biodiversity Hotspot, where the species has not been collected since its description as new to science. Stellaria ruderalis was discovered at 14 sites in eastern and central Georgia (2022–2023) and northern Armenia (2023). It inhabited various ruderal habitats as well as deciduous and mixed forests. It is presumably a common component of the regional flora, although overlooked to date. Thus, its first IUCN classification is proposed here as Data Deficient (DD).

Clathrus archeri (Berk.) Dring, an alien saprotrophic fungus originating from Australia and New Zealand has been present in Europe for over 100 years. From its first observation in 1920 in France, it has spread all over Europe, and is among the better surveyed alien saprotrophic fungi with respect to its spread and distribution. Despite this, data about C. archeri in Croatia in the scientific literature are very scarce. To fill the current gap on the presence and distribution of C. archeri in Croatia, we collected reliable available data on its presence, analysed several environmental factors (climate, soil acidity, topography) on those localities, and developed habitat suitability models using Maxent software. We found out that the fungus has been present in Croatia for over 20 years, so we synthesized information on 25 observations, which were all but one placed in the Continental NATURA 2000 biogeographical region of the country. Localities were situated between 104 and 532 m. a.s.l., with mean annual temperatures ranging from 8.1 to 10.9 °C, and annual precipitation ranging between 815 and 1620 mm. On all localities acid soil reactions were present with pH values below 6.8. Although the current number of observations is moderate, in terms of its spatial distribution we can consider C. archeri a widespread alien fungus in Croatia. Based on the habitat suitability models developed here, and data about its ecology from the literature, we can expect more and spatially broader observations of C. archeri in the future.

Despite more than 30 years of investigations, the knowledge of the composition and spatial distribution of marine benthic diatoms along both coasts of the Adriatic Sea is still limited. The distribution and a checklist of marine benthic diatom taxa in the Mediterranean sub-basin of the Adriatic Sea are presented based on literature data. The nomenclature is brought up to date and synonyms are included. Eight hundred and twenty-two species belonging to 70 families and 163 genera have been reported. The number of pennate species represented was 719. Families with the highest number of genera were: Naviculaceae (8), Bacillariaceae (7), Surirellaceae (6), Fragilariaceae (6). The highest number of taxa belonged to the Naviculaceae (95) and Bacillariaceae (88). The most numerous genera were Mastogloia (65 taxa), Navicula (62), Nitzschia (53), Amphora (52), Diploneis (43), Cocconeis (37), Halamphora (24), Achnanthes (22), Licmophora (22), Tryblionella (19), Fallacia (15), Surirella (14), Grammatophora (13), and Lyrella (12). This study focused on the areas of investigation according to the literature reviewed and showed that many areas have to be investigated. Nevertheless, this first comprehensive checklist of marine benthic diatoms in the Adriatic Sea, updated with recent literature, is a valuable tool. However, it is important that this update has been progressive over time. Incorporating data on diatom taxa will improve the overall diversity of microalgae and our knowledge of the ecology of coastal ecosystems.

The black pine is a characteristic Mediterranean pine species and extends from Spain eastward to Southern France, Italy, Austria, the Balkans and Türkiye. Black pine is a fire tolerator and has a distinctive natural fire regime differently from the serotinous red pine and Aleppo pine forests in Mediterranean. Black pine forests are one of the ecosystems that are most affected by changing fire regimes. Fires in these forests generally occur as low intensity surface fires. The black pine is a light-demanding species and in pure stands it forms single layer structure with self-pruning. It also has a thick bark. Therefore, heat during surface fires does not have a lethal effect on the trees and crown fires will not be generated due to self-pruning. However, with changing climatic conditions and forest structure based on human use and management, the fires in black pine forests have begun to become crown fires in large areas. Since the black pine does not have any adaptation to crown fires, the trees are killed and no regeneration occurs. This process results in the degradation of black pine forests into other vegetation types such as oak woodlands, rock rose ( Cistus spp.) scrublands or bracken fern ( Pteridium aquilinum L. (Kuhn)) herbaceous vegetation. This holds true for the whole of the distribution of the black pine in the Mediterranean. Therefore, a silvicultural approach ensuring fires occur as surface fires only should be employed in the existing black pine forests and the areas degraded after fires should be restored in an ecological way to re-establish the black pine.

Stachys ocymastrum (L.) Briq. (Lamiaceae) is an annual species native to the Western Mediterranean. During fieldwork, it was found in a ruderal site in the village of Veli Iž on the island of Iž (Zadar archipelago, Croatia) in May 2024. Since there are no earlier records of this species in Croatia, it should be considered a new taxon of this country’s flora and included in the current Flora Croatica Database . Additionally, this study reports S. ocymastrum for the first time on the eastern part of the Adriatic Basin.
