An observational study on changes in biometry and generation time of Odontophora villoti (Nematoda, Axonolaimidae) related to petroleum pollution in Bizerte bay, Tunisia.

Introduction We conducted a yearly polluted-reference sampling to assess the effects of petroleum pollution on life cycle characteristics of the meiobenthic nematode Odontophora villoti. Samples were taken every 15 days between 26 November 2004 and 25 November 2005 from two beaches of Bizerte bay (Tunisia), Rimel and Tunisian Refining Industries Company (TRIC). The latter site is located in front of the “Tunisian Refining Industries Company” runoff.
