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
This is FLAVI. FLAVI is a Flowthrough Light and Velocity Incubator, and she is great. We built FLAVI so that we could grow Macrocystis pyrifera meristems, on land, under very controlled light intensities and uni-directional water velocities. Since M. pyrifera uses a mix of two carbon uptake strategies in seawater–they can passively take up CO2, … Continue reading Kelp and El Niño – Not Friends.
