Nevertheless, this new approach to studying symbiosis offers a novel pathway to reconstruct paleo-symbiosis in extinct foraminifera—an essential piece of information for interpreting numerous geochemical proxies.

However, we also show that this relationship can be more complex in regions with strong environmental gradients, where additional factors influence nitrogen isotopes.

In this study we show that foraminifera-bound nitrogen isotopes (FB-δ15N) distinguish between symbiont-bearing and symbiont-barren foraminifera. FB-δ15N shows a clear signal of dinoflagellate symbiosis and may even identify other symbionts like chrysophytes or pelagophytes.
