Characterizing and quantifying in situ metabolisms remains both a central goal and challenge for environmental microbiology. Here, we used a single-cell, multi-isotope approach to investigate the anabolic activity of marine microorganisms, with an ...

Ocean acidification reduces demersal zooplankton that reside in tropical coral reefs [PDF]
The in situ effects of ocean acidification on zooplankton communities remain largely unexplored. Using natural volcanic CO2 seep sites around tropical coral communities, we show a threefold reduction in the biomass of demersal zooplankton in high-CO2 ...

Ediacara biota flourished in oligotrophic and bacterially dominated marine environments across Baltica. [PDF]
Middle-to-late Ediacaran (575-541 Ma) marine sedimentary rocks record the first appearance of macroscopic, multicellular body fossils, yet little is known about the environments and food sources that sustained this enigmatic fauna.

Spontaneous evolution of heterotrophy in cultured dinoflagellate algae
Acquisition of chloroplasts by an early eukaryote and their subsequent spread across eukaryotes is well understood. However, evolution can be undone, and many important lineages (especially in the Apicomplexa) have lost photosynthesis, returning to heterotrophy.

The effects of intense fire on headwater streams of the Colville National Forest, WA [PDF]
Thesis (M.S.) University of Alaska Fairbanks, 2006Forest fires play an important role in shaping ecosystems, and there has been growing concern on the effects of high intensity fires on forest and aquatic ecosystems.

Net heterotrophy and carbonate dissolution in two subtropical seagrass meadows
. The net ecosystem productivity (NEP) of two seagrass meadows within one of the largest seagrass ecosystems in the world, Florida Bay, was assessed using direct measurements over consecutive diel cycles during a short study in the fall of 2018.

Evolution of heterotrophy in chrysophytes as reflected by comparative transcriptomics
Shifts in the nutritional mode between phototrophy, mixotrophy and heterotrophy are a widespread phenomenon in the evolution of eukaryotic diversity.

Mixotrophic species use both organic and mineral carbon sources. Some mixotrophic plants combine photosynthesis and a nutrition called mycoheterotrophy, where carbon is obtained from fungi forming mycorrhizal symbiosis with their roots. These species can

Nitrogen Fixation Aligns with nifH Abundance and Expression in Two Coral Trophic Functional Groups
Microbial nitrogen fixation (diazotrophy) is a functional trait widely associated with tropical reef-building (scleractinian) corals. While the integral role of nitrogen fixation in coral nutrient dynamics is recognized, its ecological significance ...
