Most intertidal rocky systems are exposed to severe tidal, diurnal, and seasonal changes in environmental parameters. In addition, they show extreme vulnerability anthropogenic impacts. Research on multiple drivers is therefore crucial understand the complexity of their potential interactions. Here, we first give an overview natural environment impacts climate change shore systems, then focus d...

Seabird guano is recognized as a powerful fertilizer and its entry into the intertidal zone of seabird breeding islands off the west coast of South Africa is hypothesized to cause enhanced intertidal algal production. Intertidal nutrient levels and algal production were measured monthly on the shores of seabird islands and on nearby mainland shores where no aggregabons of seabirds occur. The sh...

The predatory xanthid crabs Eurytjum limosurn and Panopeus herbstii are common components of benthic assemblages in different intertidal habitats within salt marshes around Sapelo Island. Georgia, USA. E. limosum feed primarily on other crabs and are found where cordgrass Spartina altemiflora stems are the dominant structural elements in the environment. P: herbstii feed largely on bivalve moll...

Photosynthetic processes in Zostera japonica, an upper intertidal species, were found to be more severely affected by desiccation than Z. marina, a lower intertidal and subtidal species, at comparable levels of tissue water content. The data indicate that photosynthetic responses to desiccation at the level of the individual leaf are insufficient to explain observed patterns of intertidal seagr...

To elucidate the determinants of intertidal invertebrate body temperatures during aerial exposure, I developed deterministic models using the environmental inputs of solar radiation, air temperature, ground temperature, and wind speed to predict the body temperatures of intertidal mussels (Mytilus spp.). Combined with field studies, these models were used to determine the effects of body size o...

A wetting and drying scheme (WDS) is developed to incorporate into a three-dimensional sigmacoordinate coastal ocean model (POM; Blumberg and Mellor, 1983) with proposing an extended logarithmic profile within and above bed boundary layers to accurately simulate 3D hydrodynamics in extremely shallow coastal seas. While the WDS is simplistically formulated, it can selectively retain the computat...
