چکیده انگلیسی
We investigated Spartina alterniflora invasions, their relationship with shoreline dynamics and effects on crab communities in the Yellow River estuary, China, where shoreline dynamics have been accelerated due to human-mediated estuarine sediment deposition and sea-level rise. We determined the distribution of Spartina with extensive ground surveys, and quantified shoreline dynamics between 2001 and 2009 by interpreting satellite images. We used pitfall traps to sample crab populations in Spartina-invaded habitats and non-invaded mudflats in 2009 and 2010. Large areas (>0.5Â km2) of Spartina plants were found at three locations in the estuary. The seaward limit of Spartina at each location generally coincided with the present shoreline, regardless of historical shoreline advance or retreat. Crab communities in Spartina-invaded habitats significantly differed from those in non-invaded habitats. The total number and biomass of crabs caught per trap were much higher in Spartina-invaded habitats than in non-invaded habitats, however, species richness and Shannon diversity were much lower. These results suggest that Spartina invasions are likely to keep pace with shoreline dynamics accelerated by global change and have significant ecological consequences for crab communities. These issues should be taken into account to improve the use and management of Spartina, especially in rapidly accreting estuaries with large-area mudflats that are important habitats but prone to Spartina invasions.
