Vegetation transitions drive the autotrophy–heterotrophy balance in Arctic lakes
Limnology and Oceanography Letters, 2018 “Arctic greening” will alter vegetation quantity and quality in northern watersheds, with possible consequences for lake metabolic balance. We used paleolimnology from six Arctic lakes in Greenland, Norway, and Alaska to develop a conceptual model ...

Carbon fixation by basalt-hosted microbial communities
Frontiers in Microbiology, 2015 Oceanic crust is a massive potential habitat for microbial life on Earth, yet our understanding of this ecosystem is limited due to difficulty in access. In particular, measurements of rates of microbial activity are sparse. We used stable carbon isotope

Co-variation between autotrophy and heterotrophy in the Mediterranean coral Cladocora caespitosa [PDF]
, 2010 This study quantifies the relative contributions of autotrophy and heterotrophy to the energy budget of the temperate scleractinian species Cladocora caespitosa Linnaeus 1767. Colonies were incubated under different light and feeding regimes, and changes

Comparative biochemistry of CO2 fixation and the evolution of autotrophy.
International microbiology : the official journal of the Spanish Society for Microbiology, 1999 Carbon dioxide fixation is a polyphyletic trait that has evolved in widely separated prokaryotic branches. The three principal CO2-assimilation pathways are (i) the reductive pentose-phosphate cycle, i.e. the Calvin-Benson cycle; (ii) the reductive citric acid (or Arnon) cycle; and (iii) the net synthesis of acetyl-CoA from CO/CO2, or Wood pathway ...

Nature CommunicationsThe direct reduction of CO2 into one-carbon molecules is key to highly efficient biological CO2-fixation. However, this strategy is currently restricted to anaerobic organisms and low redox potentials.

Productivity-Diversity Relationships from Chemolithoautotrophically Based Sulfidic Karst Systems [PDF]
International Journal of Speleology, 2009 Although ecosystems thriving in the absence of photosynthetic processes are no longer considered unique phenomena, we haveyet to understand how these ecosystems are energetically sustained via chemosynthesis.

Investigating functionnal traits on oil palm carbon allocation strategy using C on sugars and organic matter. I. Leaves: Passage from heterotrophy to autotrophy [PDF]
, 2008 This work was conducted on Elaeis guineensis Jacq. (oil palm) in North Sumatra (indortesia), and carbon isotope discrimination was used to get a better understanding of the major ecophysiological traits involved in the growth and development of this ...
