Physical and Ecological Forcings Drive the Particle Dynamics and Enhanced Carbon Export Efficiency in the Tropical Marginal Sea

open access: yesGeophysical Research Letters, Volume 53, Issue 8, 28 April 2026.
Abstract Marginal seas contribute disproportionately to the ocean carbon cycle but remain poorly constrained due to strong spatial and seasonal variability. Here, we combine newly collected in situ particle imagery with machine learning to reconstruct monthly, depth‐resolved climatologies of particle biovolume and size distribution in the South China ...

Mesophotic corals in Hawaii maintain autotrophy to survive low-light conditions. [PDF]

open access: yes
In mesophotic coral ecosystems, reef-building corals and their photosynthetic symbionts can survive with less than 1% of surface irradiance. How depth-specialist corals rely upon autotrophically and heterotrophically derived energy sources across the ...

A Systematic Review of Biofloc Technology and Periphyton in Giant Freshwater Prawn (Macrobrachium rosenbergii) Aquaculture

open access: yesAquaculture, Fish and Fisheries, Volume 6, Issue 2, April 2026.
Biofloc technology and periphyton‐based systems enhance the sustainable production of giant freshwater prawn (Macrobrachium rosenbergii). A PRISMA‐guided review (2005 – 2024) shows that BFT improves survival (75 – 78 %) and feed efficiency, while periphyton supports natural productivity in grow‐out.

Biochemistry and genetics of autotrophy in Methanococcus [PDF]

open access: yes, 2009
The project investigated fundamental aspects of carbon metabolism and genetics in the methane-producing archaeon Methanococcus maripaludis. The project yielded 23 peer-reviewed publications and five reviews from 1997-2007. PDFs of the peer-reviewed publications are included in the next section. Some papers of special interest are listed below.

Endemic Mediterranean seagrasses poised to survive climate change challenges

open access: yesEcological Applications, Volume 36, Issue 3, April 2026.
Abstract Understanding the current and future trajectories of critical habitats is essential for biodiversity conservation and ecosystem management, especially in semi‐enclosed environments such as the Mediterranean Sea. Endemic habitats in the Mediterranean, such as Posidonia meadows, are crucial for marine biodiversity, nutrient cycling, oxygen ...

Size distribution of autotrophy and microheterotrophy in reservoirs: implications for foodweb structure [PDF]

open access: yes, 1981
Particle size is a primary determinant of resources available to consumers and of the efficiency of energy transfer through planktonic food chains. Dual radioisotopic labeling (with /sup 14/C-bicarbonate and /sup 3/H-acetate) and size fractionation of ...

Plastid Genome Evolution Across the Roridulaceae–Sarraceniaceae Clade (Ericales) in Relation to Carnivorous Strategies

open access: yesEcology and Evolution, Volume 16, Issue 4, April 2026.
The Roridulaceae–Sarraceniaceae clade exhibits strikingly divergent carnivorous strategies, providing a framework to examine how trophic shifts influence plastid genome evolution. Comparative plastome analyses reveal recurrent ndh gene disruption across species, while Roridula gorgonias shows pronounced genomic restructuring, including elevated ...

Biochemical Basis of Obligate Autotrophy in Nitrosomonas europaea [PDF]

open access: yesJournal of Bacteriology, 1969
The specific activities of isocitric dehydrogenase, α-ketoglutaric dehydrogenase, succinic dehydrogenase, malic dehydrogenase, and reduced nicotinamide adenine dinucleotide (NADH) oxidase were determined in extracts of Nitrosomonas europaea and compared with the corresponding values for Anacystis ...

Changes in 13C/12C of oil palm leaves to understand carbon use during their passage from heterotrophy to autotrophy

open access: yes, 2009
The carbon isotope composition of leaf bulk organic matter was determined on the tropical tree Elaeis guineensis Jacq. (oil palm) in North Sumatra (Indonesia) to get a better understanding of the changes in carbon metabolism during the passage from ...

Light and tidal inundation and exposure regulate the sensitivity of estuarine benthic greenhouse gas fluxes to warming and ocean acidification

open access: yesLimnology and Oceanography, Volume 71, Issue 4, April 2026.
Abstract Coastal sediments are globally significant sources and sinks of greenhouse gases (GHGs), yet their contributions to climate feedbacks of warming and ocean acidification remain uncertain, in part due to limited understanding of short‐term variability.
