Background: The dataset contains records of vascular plant species occurrences and distribution in 39 old cemeteries of the Right-Bank Dnipro Grass Steppe District (southern Ukraine). It documents 635 vascular plant species. Notably, the high vascular plant diversity of old cemeteries includes 58 protected species (10.4% of the total recorded flora) with varying conservation statuses. The dataset underscores the conservation significance of old cemeteries in southern Ukraine by documenting the presence of protected species. Old cemeteries contribute to the conservation of endangered and protected vascular plant species outside legally protected steppe areas. Therefore, where they are abundant, they may play an important role in the future restitution of the European and Eurasian steppes.

New information: The dataset contains 6,923 occurrences of vascular plants (635 species) recorded in 2023-2024 in 39 old cemeteries of the Right-Bank Dnipro Grass Steppe District. The dataset includes information on 427 occurrences of 58 protected species of particular conservation interest mentioned in Resolution 6 of the Bern Convention as well as in the Red Data Book of Ukraine and regional Red Lists. This dataset highlights the significance of old cemeteries as pivotal refugia for vascular plant biodiversity within southern Ukraine. The high number of endangered and protected vascular plant species present in old cemeteries provides a critical opportunity for future conservation efforts, thereby contributing directly to biodiversity protection objectives.

Background: The subfamily Rogadinae comprises several genera, amongst which Aleiodes Wesmael, 1838 is the most species-rich, with more than 632 species described worldwide and many others likely remaining undiscovered.

New information: In this study, we report three species of Aleiodes newly recorded from South Korea: Aleiodes angustipterus van Achterberg & Shaw, 2016, Aleiodes euproctis He & Chen, 1990 and Aleiodes malichi Butcher et al., 2012.

Background: Epeus is a genus of jumping spiders (Salticidae) comprising 20 species, four of which have been recorded in Vietnam.

New information: In this paper, we present descriptions and illustrations of two jumping spider species of the genus Epeus from Vietnam. Epeus bicuspidatus (Song, Gu & Chen, 1988) is recorded from the country for the first time, while Epeus taybac Vu & Pham, sp. nov., is described here as new to science. These findings improve the current understanding of Epeus diversity in Vietnam, bringing the total number of known species of this genus in the country to six.

This study examines the effects of forest vegetation structure on the richness, abundance and composition of bird communities in four different Mediterranean habitats in north-eastern Algeria. Thirty bird species were recorded in the four sampled habitats, belonging to six orders and 14 families. The order Passeriformes is the most represented, with 21 species. Results indicate that cork oak (Quercus suber) and zeen oak (Quercus faginea) forests, characterised by a complex vertical structure and a closed canopy, support a rich and typically forest-dwelling bird community. In contrast, pine (Pinus pinaster) forests exhibit lower species richness and are dominated by generalist species, tolerant to habitat disturbance. Vegetation parameters such as tree height (r = 0.56), shrub cover (r = 0.49) and ecological vegetation volume (r = 0.58) were positively correlated with avian richness. With average species richness values of 18.5 and 16.3 species per plot, respectively, zeen oak forests and mixed forests had the highest levels of avian diversity, while pine forests had the lowest (average = 9.7 species).

Background: Urbanisation has caused significant changes in material cycles, alterations in river flow rates and depths and modifications to habitats for aquatic organisms. These changes have led to disruptions in the movement and dispersal of aquatic species, as well as shifts in biodiversity. The loss of habitats due to urbanisation has resulted in a decline in species diversity across a variety of taxonomic groups. Aquatic organisms, in particular, are adversely affected by habitat loss caused by river channel modifications and the invasion of non-native species. It is generally reported that, in regions where invasive species have established and native species have declined, fish fauna tend to homogenise, leading to a substantial reduction in diversity. However, the impact of urbanisation on fish fauna varies depending on local ecosystems, the degree of urbanisation and the time elapsed since urban development. Therefore, it is crucial to gather region-specific information on how fish fauna have been altered by urbanisation. The study area in this research, the Kitakyushu metropolitan area, is one of Japan's oldest heavy industrial zones and many of its rivers have been affected by channel straightening and concrete lining.

New information: A fish survey was conducted at 100 locations within the Kitakyushu metropolitan area during the summer period (from 16 July to 4 October 2024), focusing on river sections modified by channel straightening and concrete lining due to urbanisation. The survey resulted in collecting 30 genera and 32 species from nine orders and 19 families, for a total of 9,253 individuals. Amongst the species collected, rare species, such as the Bitterling, Liobagrus reini and Misgurnus anguillicaudatus, were also found (The Japanese Red List). Although the number of individuals was limited, these native rare species were found in inhabited rivers significantly altered by human activity. Additionally, invasive species including Lepomis macrochirus, Micropterus salmoides (Lacepède, 1802) and Channa argus (Cantor, 1842) were recorded. Despite accounting for only 0.5% of the total fish population, the highly predatory nature of these invasive species warrants proactive management, including the enhancement of impounded water environments through structures such as weirs, to mitigate their potential ecological impact.

Background: The Mediterranean Basin is recognised as global biodiversity hotspot, with islands playing a crucial role in sustaining high levels of endemism due to their geological complexity, biogeographical history and habitat heterogeneity. Despite this, many Mediterranean islands remain underexplored from a faunistic perspective, particularly regarding nocturnal Lepidoptera.

New information: This study provides new faunistic data on the nocturnal macrolepidoptera of two protected areas in the north of Sardinia: Asinara and La Maddalena islands. A total of 875 specimens were collected, representing 98 species across four families. Of these, 62 species were recorded on the La Maddalena and 78 on the Asinara islands. Notably, nine species are newly reported for La Maddalena, increasing the known macrolepidopteran fauna of the archipelago. Our study provides novel insights especially to the knowledge of the Asinara Island which remains poorly investigated due to its historical restricted access. This study offers a baseline for future ecological and biogeographical research and highlights the need for ongoing faunistic surveys in Mediterranean island systems. Furthermore, this study underscores the biogeographical importance of these islands which host rich moth communities despite their small size.

Background: Rhinolophus acuminatus was first evaluated for its conservation status in 1996, with subsequent assessments conducted in 2008 and most recently in 2019, during which it was categorised as Least Concern. These evaluations, however, were largely based on limited occurrence records and a general list of countries where the species was known to occur. Recent discoveries have documented new distribution records, indicating a broader geographic range than previously recognised. Additionally, the availability of a more precise locality data has contributed to a more comprehensive understanding of the species distribution and ecological context.

New information: This study provides novel insights into the distribution of Rhinolophus acuminatus, including newly-documented localities, an updated elevational range and refined regional records. Notably, Sarawak (Malaysian Borneo) and Brunei were not previously recognised as part of the species' range during its most recent IUCN assessment. We report the first confirmed occurrence of R. acuminatus in Sarawak, specifically within Gunung Mulu National Park, a UNESCO World Heritage Site, known for its exceptional biodiversity and extensive limestone karst systems. Additionally, a new locality record from Melilas in Brunei further expands the species' known distribution on the island of Borneo. The record from Sarawak represents a newly-documented extant range within Malaysian Borneo, while the Brunei record constitutes a new country record for R. acuminatus. This study also presents the most comprehensive and detailed locality data for the species since its last detailed assessment in 2019. The species' elevational range has been revised from the previously reported maximum of 1,676 m above sea level (a.s.l.) in the 2019 IUCN assessment to a new upper limit of 3,943 m a.s.l., based on records from Mount Kinabalu in Sabah, Malaysian Borneo, indicating the species' presence in upper montane forest habitats. Furthermore, this study provides the first quantitative estimates of the species' Extent of Occurrence (EOO), calculated at 6,957,361.5 km², Area of Occupancy (AOO) at 608 km² and 149 number of locations. EOO mapping further illustrates the species' broad distribution across the Southeast Asian region. Collectively, these findings offer critical data for future reassessments of the conservation status of R. acuminatus under the IUCN Red List criteria.

Background: The information in this article corresponds to a compilation of data from scientific journals, ornithological collections and virtual libraries (xeno-song, eBird and Biomap), as well as our contributions during more than 15 years of studies in Tolima. Together, this information allows us to understand the diversity of birds in the region. In addition, this article includes data on localities and the altitudinal and geographical distribution of each species. The results indicate the presence of 800 bird species in Tolima, of which 24 are endemic, 69 are near-endemic and 82 are migratory. Furthermore, 42 species face some degree of threat, two are classified as having deficient data and four have been introduced.

New information: This list constitutes a reference for studies of birds of the Upper Magdalena Valley. It is a necessary tool for conservation plans in this region of the country.

Background: The family Xenodermidae comprises six recognised genera: Xenodermus Reinhardt, 1836; Achalinus Peters, 1869; Stoliczkia Jerdon, 1870; Fimbrios Smith, 1921; Parafimbrios Teynié, David, Lottier, Le, Vidal & Nguyen, 2015; and Paraxenodermus Deepak, Lalronunga, Lalhmingliani, Das, Narayanan, Das & Gower, 2021. Amongst these, Achalinus Peters, 1869, is the most species-rich taxon. It is widely distributed across eastern and south-eastern Asia, ranging from northern Vietnam to south-western China and extending partially into Japan.Achalinus hunanensis Ma, Shi, Xiang, Shu & Jiang, 2023 was originally described, based on two male specimens collected from Huaihua City and Changsha City, Hunan Province, China. Subsequent surveys also recorded this species in Dushan County, Guizhou Province, marking its first known occurrence there and providing the first description of female specimens. During our herpetological surveys in 2024, three Achalinus specimens were collected from Guangxi Zhuang Autonomous Region, China. Due to severe desiccation, DNA extraction was unsuccessful for specimen GXNU2024090120. However, we analysed mitochondrial DNA sequence data from the remaining two specimens and compared them with all known congeners. Both the morphological and molecular evidence strongly support the identification of the specimens from Jiuwanshan National Nature Reserve as A. hunanensis. Additional morphological data are provided here, based on the examination of three newly-collected individuals.

New information: In this study, we provide a detailed morphological description of A. hunanensis, based on newly-collected specimens. We also present an updated species diagnosis incorporating additional morphological characters and revise the known distribution of A. hunanensis.
