Why mixotrophy flourished in water but rarely on land
Frontiers in Ecology and EvolutionMixotrophy, the ability to combine photosynthesis with heterotrophic acquisition of carbon or nutrients, is now recognized as a central feature of aquatic microbial food webs and a recurrent strategy in several protist and simple animal lineages.

The contingent advantage of photosymbiosis in coral evolution
Proceedings of the National Academy of SciencesThe ecological success of modern reef-building corals is rooted in photosymbiosis, yet its macroevolutionary benefit remains unclear. Analyzing the Phanerozoic record of inferred zooxanthellate (Z) and azooxanthellate (AZ) corals over geologic time scales using Bayesian methods, we identify a fundamental shift in diversification ...

Photosymbiosis in planktonic foraminifera across the Palaeocene-Eocene Thermal Maximum
, 2018 Under stress, corals and foraminifera may eject algal symbionts ('bleach'), which can increase mortality. How bleaching relates to species viability over warming events is of great interest given current global warming.

Frontiers in Ecology and EvolutionIntroductionCoral reef ecosystems are increasingly threatened by climate change-induced thermal stress, leading to widespread bleaching events. Giant clams (Tridacna spp.) are key photosymbiotic reef inhabitants that harbor extracellular dinoflagellate ...

Photosymbiosis on a Mid-Devonian Reef: Evidence from Coral-Bound Nitrogen Isotopes
, 2022 Scleractinian corals are believed to owe much of their ecological success in low-nutrient, low-productivity tropical surface waters to a symbiotic network of diverse reef organisms.

Stable Isotopic Signals and Photosymbiosis in Late Paleocene Planktic Foraminifera
, 1994 Late Paleocene planktic foraminifera exhibit strong positive correlations between carbon isotopic values and test mass, but negative correlations between oxygen isotopic values and test mass.

Effects of photosymbiosis and related processes on planktic foraminifera-bound nitrogen isotopes in South Atlantic sediments [PDF]
BiogeosciencesForaminifera often form symbiotic relationships with photosynthetic algae, providing a host environment and inorganic nutrients in exchange for photosynthetic organic matter from the algal symbiont.

Data from: Species selection and the macroevolution of coral coloniality and photosymbiosis
, 2013 Differences in the relative diversification rates of species with variant traits is known as species selection. Species selection can produce a macroevolutionary change in the frequencies of traits by changing the relative number of species possessing ...

Functional brain regeneration in the acoel worm Symsagittifera roscoffensis [PDF]
, 2015 The ability of some animals to regrow their head and brain after decapitation provides a striking example of the regenerative capacity within the animal kingdom.
