Hot off the presses: Amino Acid Compound Specific #Isotope Analysis (#AACSIA) to understand #coral nutrition. We show corals are reliant on symbiont-derived carbon and nitrogen for AA. Flexible nutrition? Not so much. @GatesCoralLab @himb_soest bit.ly/3uxZOe2
Amino acids in the AACSIA terminology are essential (from diets) or non-essential (synthesized) for carbon, and either trophic (change with feeding) or source (reflect origins) for nitrogen. At the time of our experiment no one had tested C and N AACSIA in corals.
Corals are weird. They can produce a lot of AA, most animals can't. Their symbionts also produce nearly all AA, as they are plants. So together the holobiont may produce everything "in house" or source building blocks from feeding on plankton.
Ever wonder about the hidden secrets of a #CoralReefs water column? Well #manta #mantaray and #TeamCoral and #TeamFish surely want to know about the available food to eat! There’s a lot of info hiding in plain sight in clear (ish), tropical waters (1/n) doi.org/10.1007/s00338… 
Happy to share the 3rd paper from my PhD! Biogeochemical variability and trophic status of shallow and #mesophotic #CoralReef water column following a #coral bleaching event in the #Maldives (2/n) @CoralReefs_UQ @CoralCOE @SpringerCORE doi.org/10.1007/s00338…

Our article on the origin and health status of first-generation Africans from the Viceroyalty of New Spain is out now in @CurrentBiology! disq.us/t/3o8nra4 Here’s the #thread in case you can’t make the complete read:
These African individuals were first noted by @MezaAbigail and colleagues to be not Native Americans and found in a hospital which was dedicated to care exclusively for the indigenous population of the Viceroyalty of the #NewSpain
Here’s a look at the excavation site: (from: arqueologiamexicana.mx/mexico-antiguo…)
Excited to share our recent work (& last chapter of my PhD) in #ISMEJ on #Symbiodiniaceae functional diversity, niche partitioning & isotopes in #corals across a rapid light-attenuation gradient (a thread..) @GatesCoralLab @himb_soest @uhmanoa @DonahueLab go.nature.com/2N1FDSm
@GatesCoralLab @himb_soest @uhmanoa @DonahueLab Corals depend on their symbionts (Symbiodiniaceae) for food, but #heterotrophy is also important--especially during periods of stress and low autotrophy (low light). But these symbionts show differences in autotrophic capacity and some (#Durusidinium spp.) may be opportunistic.
@GatesCoralLab @himb_soest @uhmanoa @DonahueLab Isotopes are a great way to understand nutrition and trophic ecology in ALL living things. We used isotopes and physiology metrics to understand how a single Hawaiian coral species (Montipora capitata) dominated by 2 different symbiont species were balancing auto- & heterotrophy.
