dc.description.abstractThe extremely cold and infertile Antarctic is one of the harshest terrestrial ecosystems for the growth of vegetation, except for the grass species Deschampsia antarctica. We examined the main soil variables that determine the distribution of D. antarctica in King George Island by using Bayesian analysis of variance and regression methods. This study compared the density of D. antarctica between 2 sites;the density remained relatively stable at site 1, whereas it severely decreased in site 2 over a period of 3 years. Although site 2 showed better soil conditions for the growth of D. antarctica such as organic matter content, available phosphorus, NO3-N, and extractable cations, its poor drainage and low soil pH may affected the survival of D. antarctica by altering nutrition availability and inhibiting root respiration. Poisson analysis of covariance showed that the early melting of snow was also an important factor in the distribution of D. antarctica. The results also showed that seabirds and mammals might have greatly influenced the distribution of the grass species in King George Island by transferring nutrients from the sea onto land;thus, changing the chemical characteristics of the soil.ion of D. antarctica in King George Island by using Bayesian analysis of variance and regression methods.
