Whether in terrestrial or freshwater and marine ecosystems, the management of invasive non-native species has continued to be a difficult challenge for scientists and public authorities. Invasive species may directly cause the extinction of other species while indirectly causing changes in ecosystem functioning. Invasive terrestrial species have historically been addressed more quickly due to human bias towards their own habitable space. However, this tendency hinders the development of management strategies against aquatic invasive species. Additionally, aquatic ecosystems (especially marine ecosystems) are more disadvantaged in implementing actions against biological invasions than terrestrial ecosystems due to the open nature of marine environments, the size of the recipient area, and the inherent ability of the invader. Consequently, determining and evaluating the ecological and socio-economical impacts of invasive aquatic species is of vital importance. Range-expanded invasive species have been classified into two groups: Neonative and alien due to differences in processes of introduction or expansion. Neonatives are defined as basic range expanding species that track human-induced environmental change and have established populations, not as a result of direct movement by human agency, intentional or unintentional, or to the creation of dispersal corridors such as canals, roads, pipelines, or tunnels. Contrary to this, alien species utilize human-induced environmental changes to expand their ranges. Understanding and distinguishing ecological and socio-economical impacts of the alien/neonative species on novel environments and developing and using risk assessment adequate to their ecological requirements are essential for the success of management for invasive species. The main purpose of this Research Topic is to collect high-standard papers that aim to understand all components and ecological and socio-economical impacts of alien and neonative species’ invasion. Papers can include all or a part of the different phases of the risk analysis process (risk identification, risk assessment and, impact assessment). https://www.frontiersin.org/research-topics/32132/evaluating-invasion-processes-of-alien-and-neonative-species-via-impact-assessment-protocols

ELNAIS aims to collect and report spatial information on Aquatic Alien Species in Greek waters. It covers freshwater, marine and estuarine waters, including not only established aliens but also casual records and cryptogenic species. The ELNAIS system includes: News, List of Greek experts, Literature of findings in Greece, List of species with information on their first introduction date and source as well as photos and distribution maps. Data providers are the scientific community (publications, grey literature, and databases) as well as citizen scientists.

Using the knowledge on the feeding habits and trophic levels of fish species may have prominent role in their successful conservation and management. In this project, we are compiling and analysing available stomach content data sets of freshwater fishes in Turkey.
