Vertical distribution of the salt marsh invader Spartina alterniflora and native halophytes on the west coast of Korea in relation to tidal regimes
Smooth cordgrass ( Spartina alterniflora Loisel.), an aggressive non-native species worldwide, colonized tidal flats on the west coast of Korea in two regions differing in tidal amplitude between 1990–2004. By the time of our study in 2015, expansion had occurred both clonally and through formation of new patches, providing an opportunity to determine intertidal range, which is a key component of understanding the threat posed by S. alterniflora through competition with native halophytes or transformation of unstructured mudflat. At Ganghwa (5.69 m tidal range), S. alterniflora ranged from 3.52 to 1.34 m above Mean Sea Level (MSL). At Jindo (2.02 m tidal range), S. alterniflora ranged from 1.57 to -0.18 m relative to MSL. Thus, a wider absolute intertidal range was occupied by S. alterniflora at the megatidal vs mesotidal region, but the lower limit of S. alterniflora did not extend below MSL under megatidal conditions, a pattern that now appears to emerge consistently in both the native and introduced range. In both study regions, S. alterniflora occurred at the same elevations as other salt marsh plants, occupying an upper zone with Phragmites australis (non-native) and middle zone with several native species including Suaeda japonica . S. alterniflora occurred below native marsh vegetation at all sites, which would result in transformation of the extensive mudflats along the Korean coast.
期刊介绍:
Aquatic Invasions is an open access, peer-reviewed international journal focusing on academic research of biological invasions in both inland and coastal water ecosystems from around the world.
It was established in 2006 as initiative of the International Society of Limnology (SIL) Working Group on Aquatic Invasive Species (WGAIS) with start-up funding from the European Commission Sixth Framework Programme for Research and Technological Development Integrated Project ALARM.
Aquatic Invasions is an official journal of International Association for Open Knowledge on Invasive Alien Species (INVASIVESNET).
Aquatic Invasions provides a forum for professionals involved in research of aquatic non-native species, including a focus on the following:
• Patterns of non-native species dispersal, including range extensions with global change
• Trends in new introductions and establishment of non-native species
• Population dynamics of non-native species
• Ecological and evolutionary impacts of non-native species
• Behaviour of invasive and associated native species in invaded areas
• Prediction of new invasions
• Advances in non-native species identification and taxonomy
