Organic Carbon and Nitrogen Isoscapes of Reef Corals and Algal Symbionts: Relative Influences of Environmental Gradients and Heterotrophy

open access: yesMicroorganisms, 2020
The elemental (C/N) and stable isotopic (δ13C, δ15N) compositions and compound-specific δ15N values of amino acids (δ15NAA) were evaluated for coral holobionts as diagnostic tools to detect spatiotemporal environmental heterogeneity and its effects on ...

Feeding and thermal conditioning enhance coral temperature tolerance in juvenile Pocillopora acuta

open access: yesRoyal Society Open Science, 2021
Scleractinian corals form the foundation of coral reefs by acquiring autotrophic nutrition from photosynthetic endosymbionts (Symbiodiniaceae) and use feeding to obtain additional nutrition, especially when the symbiosis is compromised (i.e.

Morphological and trophic coupling distinguishes coral clades along a light gradient

open access: yesLimnology 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.

Physiological and Biogeochemical Responses of Super-Corals to Thermal Stress from the Northern Gulf of Aqaba, Red Sea

open access: yesFrontiers in Marine Science, 2017
Mass coral bleaching is increasing in frequency and severity, leading to the loss of coral abundance and diversity. However, some corals are less susceptible to bleaching than others and can provide a model for identifying the physiological and ...

Protist Diversity and Metabolic Strategy in Freshwater Lakes Are Shaped by Trophic State and Watershed Land Use on a Continental Scale

open access: yesmSystems, 2022
Protists play key roles in aquatic food webs as primary producers, predators, nutrient recyclers, and symbionts. However, a comprehensive view of protist diversity in freshwaters has been challenged by the immense environmental heterogeneity among lakes ...

Orchid genome evolution and trait innovation

open access: yesJournal of Integrative Plant Biology, Volume 68, Issue 8, Page 2577-2607, August 2026.
Orchids became one of the world's most diverse plant groups through genome‐driven innovations, unique relationships with fungi and pollinators, and remarkable adaptability. This review explains the origins of orchids and the evolution of their distinctive life forms, flowers, and ecological strategies and highlights promising directions for future ...

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

open access: yesPlant, 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.

Proteomics unveil a central role for peroxisomes in butyrate assimilation of the heterotrophic Chlorophyte alga Polytomella sp.

open access: yesFrontiers in Microbiology, 2022
Volatile fatty acids found in effluents of the dark fermentation of biowastes can be used for mixotrophic growth of microalgae, improving productivity and reducing the cost of the feedstock.

Trophic Diversity in Duckweed: Mixotrophy, More Than the Sum of its Extremes

open access: yesAdvanced Science, Volume 13, Issue 41, 22 July 2026.
In the context of rising DOC in aquatic environments, mixotrophic duckweed may impact carbon cycling by acting as either a carbon sink, as they absorb CO2 through photosynthesis, or a carbon source, as they release CO2 through respiration of absorbed DOC, which depends on DOC concentration, light availability, temperature, and other environmental ...
