      Benthic Food Web.

AB  - Stable isotopes of C (delta(13)C) and N (delta(15)N) were used to explore the trophic 
      structure and evaluate mercury (Hg) biomagnification in the food web of muscle of 
      three commercially important ray species from the Pacific coast of Baja 
      California Sur (PCBCS): the shovelnose guitarfish (Pseudobatos productus), banded 
      guitarfish (Zapteryx exasperata), and bat ray (Myliobatis californica). The food 
      web of these ray species predominately consisted of zooplankton, three species of 
      fish, and five species of invertebrates. Mean delta(15)N values in all species ranged 
      from 10.54 +/- 0.18 per thousand in zooplankton to 17.84 +/- 0.81 per thousand in the shovelnose guitarfish. 
      Mean delta(13)C values ranged from - 22.05 +/- 0.75 per thousand in the red crab to - 15.93 +/- 0.78 per thousand 
      in the bat ray. Mean total Hg concentration ([THg]) in all species ranged from 
      0.0009 +/- 0.0002 mg kg(-1) ww in zooplankton to 0.24 +/- 0.19 mg kg(-1) ww in the 
      banded guitarfish. The food web magnification factor was 6.38 and significantly 
      greater than 1.0. The present study describes [THg] biomagnification in the 
      benthic food web of three ray species of the PCBCS. This provides an important 
      baseline knowledge of the biomagnification dynamics and pathways of Hg in this 
      environment for these multiple interacting species.
