Increasing global trades and human activities have led to biological invasions worldwide. Furthermore, climate change increases the risk of expansions of the distribution of invasive alien species (IAS) in recent years (Diez et al. 2012). Such invasion of alien species into the native ecosystem has reduced biodiversity and altered landscape structures and ecosystem functions while also having harmful effects on the social economy and human well-being (Pejchar and Mooney 2009). Many aspects of knowledge regarding alien species are required for effective management and control programs.
As an editor of this special issue, I have a particular concern with IAS management and ecological impacts. Our interests also include the potential risk assessment of alien species and predicting invasive species spreading to protect against their harmful effects proactively. These alien species management strategies have been discussed within the 9th East Asian Federation of Ecological Societies (EAFES) International conferences in 2021, and are core to several papers within this special issue.
Atique and An’s (2022) analysis of 45 potential risky exotic fish species shows most species have a higher climate match with the Korean territories and suggest that the incoming fish species must be screened before letting them in the country. Along with paper by Khatri-Chettri et al. (2022) found out
The model results of population dynamics of the redeared slider (Wi et al. 2022) showed that if red-eared sliders expand their habitats by natural migration, their population can increase to a greater number than when they have a 99% survivorship in a fixed habitat, and suggested that further introductions of red-eared sliders into wetlands or artificial ponds should be prohibited and managed to prevent future spread of the species.
To categorize major environmental factors and traits of invasive alien, Oh et al. (2021) analyzed the 10,287 distribution points of 126 species by the hierarchical model of species communities framework. These results showed that the disturbance by anthropogenic factors or water flow had positive influences on the occurrences of alien plants.
Finally, Son et al. (2021) introduced ecological risk assessment systems for alert alien species and IAS. These proactive management systems can contribute to preventing the reduction of biodiversity by IAS in South Korea.
We hope that these studies in this issue provide insight for policymakers to control and prevent the spread of IAS.
