Chlorella vulgaris heterotrophy-to-phototrophy conversion dynamics are mostly independent of light intensity

International audienceChlorella vulgaris transition from heterotrophy to phototrophy was studied. Five stages were identified including PSU repair, pigment expression, cell division. Characteristic times were identified for each mechanism.

Heterotrophy and Lipids as Indicators of Resilience to Climate Change Stress in Scleractinian Corals

, 2017
Coral reefs are biodiverse ecosystems with high biological, cultural, economic, and recreational value that are facing multiple anthropogenic stressors, the greatest of which is global climate change via warming and ocean acidification (OA).

Simulated terrestrial runoff shifts the metabolic balance of a coastal Mediterranean plankton community towards heterotrophy [PDF]

International audienceClimate change is projected to increase the frequency and intensity of extreme rainfall events in the Mediterranean region, increasing runoffs of terrestrial matter into coastal waters.

The influence of autotrophy, heterotrophy and temperature on pelagic food web efficiency in a brackish water system

, 2011
As part of one climate change scenario, water temperature as well as the ratio between heterotrophic and autotrophic production is expected to increase; the latter at least in higher latitudes.

Potential increasing dominance of heterotrophy in the global ocean

, 2015
Autotrophy is largely resource-limited in the modern ocean. Paleo evidence indicates this was not necessarily the case in warmer climates, and modern observations as well as standard metabolic theory suggest continued ocean warming could shift global ...

Heterotrophy of Particulate Organic Matter Subsidies Contributes to Divergent Bleaching Responses in Tropical Sclaractinian Corals

Heterotrophic feeding on plankton and particulate organic matter (POM) by tropical Scleractinian corals is known to aid in the resistance and recovery from thermally induced bleaching.

Reduced heterotrophy in the stony coral Galaxea fascicularis after life-long exposure to elevated carbon dioxide

, 2016
Ocean acidification imposes many physiological, energetic, structural and ecological challenges to stony corals. While some corals may increase autotrophy under ocean acidification, another potential mechanism to alleviate some of the adverse effects on ...

Climate-dependent CO2 emissions from lakes

, 2010
Inland waters, just as the world's oceans, play an important role in the global carbon cycle. While lakes and reservoirs typically emit CO2, they also bury carbon in their sediment.

Heterotrophy in marine animal forests in an era of climate change

Biological Reviews
ABSTRACT Marine animal forests (MAFs) are benthic ecosystems characterised by biogenic three‐dimensional structures formed by suspension feeders such as corals, gorgonians, sponges and bivalves. They comprise highly diversified communities among the most productive in the world's oceans.
