Summary: There is considerable uncertainty regarding which ecosystems are most vulnerable to warming. This study found strong differentiation in heat tolerance across populations in marine and intertidal taxa, but not terrestrial or freshwater taxa. Such adaptive differentiation in the ocean suggests there may be standing genetic variation at the species level to buffer climate impacts.

Summary: Evidence suggests that quantifying and acknowledging all three components of propagule pressure is crucial for effective invasive species management plans. However, there is currently no mathematical tool available for calculating the levels of propagule pressure needed to achieve a specific establishment probability. Furthermore, establishment estimates are highly dependent on knowledge of all three propagule pressure components.

Summary: Anthropogenic pressures, such as the introduction of non-indigenous species, have had a significant impact on global biodiversity and ecosystems. This study assessed the differences in fouling assemblages within three different ports/marinas in Madeira Island, revealing significant variations in their structure. Plastic floating pontoons were found to have the highest number of non-indigenous species. Funchal harbour was identified as the primary hub for introducing these species, with recreational boating playing a role in secondary transfers. These findings highlight the importance of implementing management actions, particularly in island ecosystems, and monitoring recreational boating activities.

Summary: Human-induced environmental changes, such as the introduction of invasive species, can disrupt nutrient flows across ecosystems and have negative consequences for ecosystem function. In this study, we found that an invasive species (black rats) disrupts a nutrient pathway provided by seabirds, leading to changes in territorial behavior of coral reef fish. Rat eradication as a conservation strategy has the potential to restore species interactions and influence populations and communities at higher ecological levels.

Summary: Human activities and interventions can introduce alien species to new ecosystems beyond their natural geographical range, negatively impacting native biodiversity. This study assessed the cumulative impacts of invasive species on marine habitats in the heavily affected Aegean Sea. Coastal areas were more impacted than the open sea, with the South Aegean experiencing stronger impacts. Shallow hard substrates were the most impacted habitat type, and the most impactful species varied depending on the habitat and impact indicator used. This study provides important information for managing biological invasions and mitigating their impacts in the Aegean Sea.

Summary: The Country Compendium of the Global Register of Introduced and Invasive Species (GRIIS) is a compilation of data from 196 individual country checklists of alien species, including those that have evidence of impact at a country level. It serves as a baseline for monitoring distribution and invasion status of major taxonomic groups, and can be used for global analyses of introduced and invasive species. The Compendium allows exploration of gaps and inferred absences of species across countries, and also provides a means for updating individual GRIIS Checklists.

Summary: Most invaders are only discovered once they have become abundant enough to be casually detected or have caused changes to the recipient environment. However, when newcomers fail to establish self-sustaining populations, they are often not even documented. This study reports a probable failed early invasion caused by an unpredictable geological event, detected through sediment records that were radiometrically dated.

Summary: We present the first verified DNA barcode data for the chthamalid barnacle Rehderella belyaevi and analyze its phylogenetic and biogeographic context among other Pacific barnacle lineages. Our findings indicate that Rehderella belyaevi is closely related to Nesochthamalus intertextus and that there is genetic admixture in the Pitcairn Island population. The study also suggests that Rehderella belyaevi may continue its ocean voyages, as it has been found on floating plastic debris in the South Pacific.

Summary: The register of global extinctions of marine invertebrates in historical time has been updated, with three gastropod and one insect species removed from the list, while two gastropods, one echinoderm, and three parasites have been added. The nine extinct marine invertebrates now recognized likely represent only a small fraction of the actual number of extinctions. Urgent inventories of globally missing marine invertebrates across a wide range of phyla are needed for evaluation.

Summary: Transoceanic shipping and global development of aquaculture are the main pathways for the introduction of marine organisms, including the Polydora hoplura species investigated in this study, to new remote locations. The genetic analysis suggests that the high genetic diversity of P. hoplura in South Africa is likely the result of complex dispersal through shipping and aquaculture activities. The study raises questions about the natural distribution of P. hoplura in South Africa and proposes further exploration of its origins in the Northwest Pacific or Indo-West Pacific regions.
