Root puppet masters: Infauna shift trait-productivity relationships in submerged aquatic vegetation communities.

Submerged aquatic vegetation (SAV) growth can be limited by light and nutrient availability. Infauna are common inhabitants of SAV meadows. Their activity increases nutrient mobility, and they can positively affect plant growth, but we do not know their role in plant trait-biomass production relationships.

Resin acid δC and δO as indicators of intra-seasonal physiological and environmental variability.

Understanding the dynamics of δC and δO in modern resin is crucial for interpreting (sub)fossilized resin records and resin production dynamics. We measured the δC and δO offsets between resin acids and their precursor molecules in the top-canopy twigs and breast-height stems of mature Pinus sylvestris trees. We also investigated the physiological and environmental signals imprinted in resin δC and δO at an intra-seasonal scale.
