Persistence of coastal vegetation in supratidal zones of northern China.

Yang H, Chu J - PLoS ONE (2013)

Bottom Line: Eight separate sandy coasts of the Shandong Peninsula were sampled, representing for disturbed and undisturbed sandy coasts.Plants growing on their supratidal zones were surveyed.On this basis, we compared the relative dominances, niche widths, and commonness of all species, and also analyzed species diversities of the coasts.

ABSTRACT
Coastal vegetation comprises a number of coastal specialists and terrestrial generalists. It remains unclear how they persist on disturbed and undisturbed coastal conditions. We tested the hypothesis that coastal specialists may be superior to terrestrial generalists on supratidal zones of coasts, but their superiority can be influenced by human disturbances. Eight separate sandy coasts of the Shandong Peninsula were sampled, representing for disturbed and undisturbed sandy coasts. Plants growing on their supratidal zones were surveyed. On this basis, we compared the relative dominances, niche widths, and commonness of all species, and also analyzed species diversities of the coasts. Coastal specialists were found to be more common and widespread on supratidal zones of the sandy coasts than terrestrial generalists haphazardly invading from hinterlands. Coastal specialists exhibited lower Sørensen dissimilarities than terrestrial generalists among the coasts. Tourist trampling seemed more detrimental than pond fishery to coastal vegetation. Relative to terrestrial generalists, coastal specialists responded to human disturbances more deterministically, with steady decreases in species diversities. These evidences verify that coastal specialists are intrinsically superior to terrestrial generalists on supratidal zones of coasts, especially of undisturbed coasts, because their dispersal among coasts adapts well to local storm surge regime. They also validate that human disturbances can depress the superiority of coastal specialists, partly by inducing invasion of terrestrial generalists.

Mentions: From 2008 to 2010, we browsed sandy coasts along the coastlines in July when plants grow well, and got acquainted with all the present plants and relevant conditions. After that, we decided on eight sandy coasts for the following investigation, in view of their length adequacy and habitat typicality. The eight coasts were open for free visiting. They are located in Penglai (PL), Laishan (LS), Muping (MP), Rongcheng (RC), Haiyang (HY), Jiaonan (JN), Dashawa (DSW) and Dongjiatan (DJT) (Figure 1). Among the eight separate coasts, DSW and DJT are the nearest two, with a distance of ca. 10 km. The eight sandy coasts are separated by texture-different coasts. We observed the coasts and vegetation, and also inquired about histories of human disturbances.
