Resource-Consumer Relationships and Baseline Stable Isotopic Signatures of Food Webs in Isolated Wetlands

We examined isolated wetland food webs using stable C and N isotopes to understand resource-consumer relationships and controls on baseline isotopic signatures. Marshes were usually more 13C-enriched than cypress savannas and cypress gum swamps. Analysis of coarse particulate organic matter (CPOM) fractions indicated that C3 plants contributed the majority… CONTINUE READING
