Dinoflagellate responses to nutrients and mangrove leaf organic matter in the bioluminescent Mangrove Lagoon, St. Croix, U.S. Virgin Islands

Journal of Phycology, EarlyView.
Abstract Bioluminescent bays (biobays) are uncommon coastal ecosystems featuring dense populations of dinoflagellates, often found in mangrove‐ringed lagoons with long water retention times and high organic matter (OM) levels. Although mangroves are associated with high dinoflagellate abundance, it remains uncertain how inorganic nutrients compare with

Glacial melt disturbance shifts community metabolism of an Antarctic seafloor ecosystem from net autotrophy to heterotrophy

Communications Biology, 2021
Ulrike Braeckman et al. use in situ benthic community and benthic biogeochemistry measurements in Potter Cove on the Antarctic Peninsula to show that climate-related glacial melt disturbance shifts benthic communities from net autotrophy to heterotrophy.

Seabird-Derived Nutrients Supply Modulates the Trophic Strategies of Mixotrophic Corals

Frontiers in Marine Science, 2022
The ability of corals to modulate their nutrition strategy in response to variable nutrient supply remains poorly understood, limiting our understanding of energy flow in coral reef ecosystems and thus our comprehension of their resilience to global ...

Changes in photosynthesis and grazing facilitate growth of a mixotrophic protist under ocean acidification and warming

New Phytologist, EarlyView.
Grazing rates of Ochromonas CCMP2951 expressed as carbon obtained per mean cell volume (a) and Caut/het‐photosynthetically fixed carbon divided by carbon obtained through grazing (b) in the four experimental treatments. Summary Mixotrophic protists capable of both photosynthesis and phagotrophy are key members of marine plankton communities.

Partial mycoheterotrophy: a common strategy in arbuscular mycorrhizal plants?

New Phytologist, EarlyView.
Proposed autotrophy to mycoheterotrophy continuum among arbuscular mycorrhizal plants. Summary The vast majority of land plants transfer part of the organic carbon they produce by photosynthesis to arbuscular mycorrhizal (AM) fungi inside their root cells; the fungi in turn help plants to take up nutrients and water from the soil.

Underground allies: Mycorrhizal flexibility facilitates orchid occurrence in post‐mining landscapes

Plant Biology, EarlyView.
Epipactis helleborine associates with largely habitat‐specific fungal communities, with limited overlap between mining and woodland sites, yet maintains comparable genetic diversity across habitats. These results highlight the role of mycorrhizal flexibility in enabling habitat shifts and expanding ecological niches in human‐altered landscapes ...

Compound Hypoxia With Heat or Acidification Stress Induces Synergistic and Additive Effects on Coral Physiology

Global Change Biology Communications, Volume 1, Issue 3, September 2026.
Multi‐stressor experiments on three coral species demonstrate hypoxia produces mostly additive effects with acidification but synergistically amplifies physiological stress under elevated temperatures. As global and local environmental change increase compound stress events on coral reefs, distinguishing hypoxia‐driven effects and interactive stressor ...

Morphological and trophic coupling distinguishes coral clades along a light gradient

Limnology and Oceanography, Volume 71, Issue 8, August 2026.
Abstract Light availability is critical to the growth and survival of most scleractinian corals due to their endosymbiotic relationship with photosynthetic dinoflagellates. Natural light gradients are expected to be associated with shifts in coral physiology, morphology, and trophic strategy.

Differential molecular responses of rapeseed cotyledons to light and dark reveal metabolic adaptations towards autotrophy establishment

Frontiers in Plant Science, 2016
Photosynthesis competent autotrophy should be established during the postgerminative stage of plant growth. Among the multiple factors, light plays a decisive role in the switch from heterotrophic to autotrophic growth. Under dark condition, the rapeseed

Vestigial Plastids in Parasitic Plants: Evolutionary Remnants or Adaptive Innovations?

Plant, Cell &Environment, Volume 49, Issue 8, Page 5401-5420, August 2026.
ABSTRACT Throughout the evolutionary history of plants, chloroplasts originating from a cyanobacterial endosymbiosis have undergone remarkable adaptation and specialization, giving rise to a multitude of plastid types. The evolution toward parasitism in plants represents a particularly extreme case of such specialization.
