Enhanced nitrogen loss may explain alternative stable states in dune slack succession
Article Abstract:
The experimental evidence are presented to show that plant species in wet dune slack systems are able to affect ecosystem processes in their favor by reducing the rate of nitrogen accumulation by coupled nitrification-denitrification, promoting their competitive position. Denitrification rates of two early successional species having radial oxygen loss (ROL) with two non-ROL late successional species in a mesocosm experiment are compared.

Testing Fox's assembly rule: does plant invasion depend on recipient community structure?
Article Abstract:
Resistance to plant invaders, following Fox's assembly rule, was explored by eliminating or decreasing the number of understory plant species in particular functional groups from plots at a riparian site in southwestern Virginia, USA. It was found that Fox's assembly rule does not hold true for these functional groups in this plant community; however, composition of the recipient community is a significant factor in community assembly.
