1. The effects of 3-methylcholanthrene, 2,3-benzanthracene and beta-naphthoflavone on xenobiotic metabolism in rainbow trout were studied. 2. These three polycyclic aromatic hydrocarbons increase hepatic arylhydrocarbon (benzo[alpha]pyrene) hydroxylase activity without altering glucuronyl transferase activity. 3. All three polycyclic aromatic hydrocarbons(More)
Microspatial arrangements of sulfate-reducing microorganisms (SRM) in surface microbial mats (~1.5 mm) forming open marine stromatolites were investigated. Previous research revealed three different mat types associated with these stromatolites, each with a unique petrographic signature. Here we focused on comparing "non-lithifying" (Type-1) and(More)
