Vegetation abundance and diversity in relation to soil nutrients and soil water content in Vestfold hills, East Antarctica
Eighteen paired sites (adjacent to vs away from sea bird nests) and six transects (downslope of nests) across Vestfold Hills were sampled for vegetation, soil nutrients, soil water content and percent rock cover. Three moss and 17 lichen species were recorded, including a new record for the lichen S...

Eighteen paired sites (adjacent to vs away from sea bird nests) and six transects (downslope of nests) across Vestfold Hills were sampled for vegetation, soil nutrients, soil water content and percent rock cover.

Sites adjacent to nesting areas generally had higher soil N and P than sites away from nesting areas; however, larger differences between site locations than within site pairs suggests considerable variation in nutrient input between nesting areas and/or redistribution of nutrients by meltwater around nests. Along transects below nesting sites, average soil total N declined from 0.22% to 0.05% within 2 m from the nest, while average total P declined more gradually from 2343 ppm P to 697 ppm P at 30 m from the nest.

Data from site pairs and transects showed that lichen diversity and abundance increased with increasing soil nutrients, with soil P having a stronger influence than soil N.
