April Stable Isotope Snapshot

Fact: The carbon stable isotope signature (∂13C) of Macrocystis pyrifera is incredibly variable. Another Fact: This variability makes the kelp signature difficult to distinguish from other primary producers such as macroalgae and phytoplankton, throwing a wrench into isotope-based studies of food chains and trophic structure. Working Hypothesis: The two carbon uptake strategies – mostly CO2 … Continue reading April Stable Isotope Snapshot
