Aim As a consequence of globalisation, biological invasions have become an increasing concern due to multifaceted ecological and socio‐economic impacts on biodiversity and ecosystem services. Despite the increasing availability and accessibility of data, a comprehensive assessment of established non‐native species and their distribution in the Iberian Peninsula has not been conducted so far. Location Iberian Peninsula, including Spain, Portugal, Andorra, and Gibraltar. Methods We compiled a harmonised dataset of 1273 established non‐native species from multiple regional, national, and global sources. We analysed taxonomic composition, introduction pathways, and native biogeographic realms. Temporal patterns were assessed using first‐record data, while spatial patterns were mapped using high‐resolution occurrence data from GBIF and national databases. Results The majority of established non‐native species are vascular plants and insects, specifically of the classes Magnoliopsida and Insecta and the families Asteraceae and Formicidae, respectively. Overall, the most common pathways of introduction were escapes from human facilities and transport‐related mechanisms (contaminant and stowaway), but their importance varies among countries. Established non‐native species were mostly native to the other regions within the Palearctic, followed by the Nearctic and Neotropical realms. Regarding the time of introduction, first records increased steadily until the last decades of the 20th century, when the introduction rate slowed down; yet new introductions persist. Finally, our spatial analysis identified that areas with high human population density and coastal zones recorded the highest number of established non‐native species. Main Conclusion The Iberian Peninsula hosts a high number and diversity of established non‐native species. Given the ongoing rise in cumulative introductions and the role of unintentional human‐driven pathways, strengthening prevention measures is vital to reduce future invasions. However, with many non‐native species already established, effective management efforts are equally crucial to curb further spread and mitigate consequent impacts, especially in areas of conservation interest.

Three species of spiders (Araneae), Altella aussereri Thaler, 1990, Mimetus laevigatus (Keyserling, 1863), and Trichoncyboides simoni (Lessert, 1904), are reported from Slovakia for the first time. These new records originate from southern Slovakia. The record of A. aussereri provides new data on the distribution and natural history of this range-restricted species of very high conservation value. The records of M. laevigatus and T . simoni in Slovakia extend their known distribution in Central Europe. Characteristic features, pictures of the habitus, copulatory organs, and habitats are presented.

Biological invasions are considered a major driver of biodiversity loss, particularly on islands. Invasive alien ants can often have severe consequences on native biodiversity. Here, we review published and new information on alien ant species found on the Mediterranean island of Cyprus, a biodiversity hotspot. Our checklist of alien ants of Cyprus includes a total of 17 species, of which nine are reported from Cyprus for the first time (*): Camponotus cf. vitiosus Smith, Cardiocondyla mauritanica Forel, 1890, Cardiocondyla obscurior Wheeler, W.M., 1929*, Hypoponera punctatissima (Roger, 1859)*, Monomorium bicolor Emery, 1877, Nylanderia jaegerskioeldi (Mayr, 1904), Paratrechina longicornis (Latreille, 1802), Pheidole fadli Sharaf, 2007*, Pheidole indica Mayr, 1879, Solenopsis sp. (thief ant)*, Tetramorium bicarinatum (Nylander, 1846)*, Tetramorium caldarium (Roger, 1857)*, Tetramorium immigrans Santschi, 1927*, Tetramorium lanuginosum Mayr, 1870*, Trichomyrmex destructor (Jerdon, 1851), Trichomyrmex mayri (Forel, 1902)*, and Wasmannia auropunctata (Roger, 1863). We did not include three previously reported alien species for which we could not find supporting specimens [ Monomorium pharaonis (Linnaeus, 1758), Nylanderia vividula (Nylander, 1846), Solenopsis geminata (Fabricius, 1804)], one based on a previous misidentification [ Cardiocondyla nuda (Mayr, 1866)], and two species now considered native to Cyprus [ Hypoponera eduardi (Forel, 1894), Monomorium subopacum (F. Smith, 1858)]. Literature records, specimens from field surveys and museum collections, the geographic origin of species, occupied habitats in Cyprus, and notes on invasiveness (spread and impact) are presented for each species. An identification key to distinguish alien from native ant species in Cyprus is provided, including widespread alien ants not yet known from Cyprus in order to support early detection, monitoring, and management efforts.

Amarasekara, K.; Perera, C.; Yatawara, M., and Jayasiri, H.B., 2024. Lesser-known species (Ipomoea imperati) from the Convolvulaceae family: First record from the Manalkaadu sand dunes of Jaffna, Sri Lanka. Journal of Coastal Research, 40(4), 803–808. Charlotte (North Carolina), ISSN 0749-0208. Coastal sand dunes are dynamic and fragile ecosystems found along some sandy shorelines. They are typically supported by a wide variety of specialized floral and faunal life. Coastal sand dunes are especially common in temperate coastal areas but are less abundant in tropical or subtropical coasts. A comprehensive study of flora in the Manalkaadu sand dune ecosystem was completed from August 2022 to May 2023, using 50-m × 5-m belt transects. The study area was divided into nine distinct locations for systematic sampling. Ipomoea imperati (Vahl) Griseb., a dicotyledonous flowering plant commonly known as fiddle-leaf morning-glory of the Convolvulaceae family, was recorded for the first time in the Manalkaadu sand dunes of the Northern Province in Sri Lanka during the study. Ipomoea imperati has smooth trailing stems that are covered with alternately arranged lanceolate, fleshy dark green leaves with a notched apex. Ipomoea imperati bloomed from September 2022 to March 2023 in the study area, and the funnel-shaped flowers were fused with white petals and yellow centers. In the area where it was discovered, the species withstood high substrate temperatures (about 29°C to 35°C), sand scouring, and moderate burial by accreted sand. Out of nine sampling locations, I. imperati was found in five locations. The plant density (two to six), plant percentage frequency (40% to 60%), Shannon Wiener diversity index (0.54 to 1.43), species evenness (0.50 to 0.90), and richness (2 to 5) were also analyzed. Thus, the density of I. imperati in five sampling locations was considered to be moderate, whereas the diversity was very low. It is designated as endangered in the National Red List 2020—Conservation Status of the Flora of Sri Lanka.

The fig-tree skeletonizer moth, Choreutis nemorana (Hübner, 1799) (Lepidoptera, Choreutidae), is a widespread species in the Mediterranean region. In October 2023 and June 2024, during pest control operations as part of the harvesting campaign in the fig groves of the Bordj Ghedir and Wilaya de Bouira regions (Algeria), C. nemorana was documented for the first time in Algeria.

Invasive non-native species (invasive species, henceforth) across all taxonomic groups are spreading globally, with numbers projected to continue growing in the future. It is difficult for governments and managers to handle this issue when the identity of invasive species or the areas of occurrence of biological invasions are not known. Here, we provide an updated list of invasive animals, plants and algae in Brazil that is fully integrated and based on the same criteria and lexicon to define invasive species across all plant and animal taxa and habitats. We list 444 invasive non-native species: 254 animals, 188 plants and 2 algae. Some of the invasive species have been present in Brazil since the beginning of the European colonization in the 1500 s, but the majority of first records in Brazil were made in the last century, with copious first records after the year 2000. The list of invasive species presented here represents the most comprehensive attempt thus far to catalog all invasive non-native species at a continental-scale for a megadiverse country. Brazil has published a national strategy with the objective of improving mechanisms and partnerships for invasive non-native species prevention, early detection and rapid response. We believe that the current list of invasive species will provide technical and scientific support for the implementation of effective measures in the management of biological invasions.

Diapterus brevirostris (Sauvage, 1879) is a fish of the family Gerreidae, native to the tropical and subtropical waters of the Pacific coast of America. A specimen of this species was captured off the coast of Asturias, Spain. To the best of our knowledge, this is the first record of the genus Diapterus in the North Atlantic. Given its small size (6.4 cm), it is likely that the species was present in the area for a relatively short time. Although the introduction pathway is unknown, the species' native area and the proximity of a major port to the site of capture suggest that ship's ballast water is the most likely vector of introduction.

The invasive species Lycorma delicatula (White) (Hemiptera: Fulgoridae) is reported from the United States. The first specimens of Lycorma delicatula were collected in Berks County, Pennsylvania, USA in September 2014. The species' North American history of distribution, pest implications, and brief observations on their biology in the New World are reviewed.

In this study, Diptera specimens photographed during nature observations in Bartın and Sakarya of Türkiye provinces were initially identified as (Preyssler, 1791) based on their photographs. Subsequently, to confirm the identification microscopically, representative female and male specimens were collected and examined under a stereomicroscope. This finding represents the first record of in the Turkish fauna.

The smallest fish of the Mediterranean Sea, pygmaean goby, Pomatoschistus nanus, and Massuti's goby, Buenia massutii, were obtained from new locations. While P. nanus specimens were collected from both the north-eastern and south-eastern Aegean Sea, B. massutii specimens were collected from two different sub-basins, Sea of Marmara and the Aegean Sea, representing the first report of this species in the eastern Mediterranean Sea. The species were identified by both morphological and molecular techniques. The present paper contributes to filling gaps in the knowledge of the limited distribution of these species in the eastern Mediterranean Sea.
