The combined effect of fire and nitrogen addition on biodiversity and herbaceous aboveground productivity in a coastal shrubland.

ABSTRACT:

Introduction

Fire and nitrogen (N) deposition each impact biodiversity and ecosystem productivity. However, the effect of N deposition on ecosystem recovery after fire is still far from understood, especially in coastal wetlands.

Methods

We selected a typical coastal shrubland to simulate three N deposition levels (0, 10, and 20 g N m^-2 year^-1) under two different burned conditions (unburned and burned) in the Yellow River Delta of North China. Soil properties, soil microbial biodiversity, shrub growth parameters, herbaceous biodiversity, and aboveground productivity were determined after experimental treatments for 1 year.

Results

We found that fire had a stronger influence on the ecosystem than N addition. One year after the fire, shrub growth
