Combustion influences on natural abundance nitrogen isotope ratio in soil and plants following a wildfire in a sub-alpine ecosystem

  title={Combustion influences on natural abundance nitrogen isotope ratio in soil and plants following a wildfire in a sub-alpine ecosystem},
  author={Edith Huber and Tina L. Bell and Mark A. Adams},
This before-and-after-impact study uses the natural abundance N isotope ratio (δ15N) to investigate the effects of a wildfire on sub-alpine ecosystem properties and processes. We measured the 15N signatures of soil, charred organic material, ash and foliage in three sub-alpine plant communities (grassland, heathland and woodland) in south-eastern Australia. Surface bulk soil was temporarily enriched in 15N immediately after wildfire compared to charred organic material and ash in all plant… CONTINUE READING
