Glacial melt disturbance shifts community metabolism of an Antarctic seafloor ecosystem from net autotrophy to heterotrophy
Climate change-induced glacial melt affects benthic ecosystems along the West Antarctic Peninsula, but current understanding of the effects on...

Autotrophy to Heterotrophy: Shift in Bacterial Functions During the Melt Season in Antarctic Cryoconite Holes
Microbes residing in cryoconite holes (debris, water, and nutrient-rich ecosystems) on the glacier surface actively participate in carbon and...

Heterotrophy vs. Autotrophy: Carbon Metabolism in the Debate on the Origins of Life in the Middle of the Twentieth Century
Nutrition, in its twentieth-century meaning in biology, denotes the relationship between a given living object—i.e. an organism, a cell—and its...

Trophic provisioning and parental trade-offs lead to successful reproductive performance in corals after a bleaching event
Warming ocean temperatures are severely compromising the health and resilience of coral reefs worldwide. Coral bleaching can affect coral physiology...

An axenic strain reveals the responses of Phaeodactylum tricornutum to external organic carbon
The model diatom Phaeodactylum tricornutum is considered a promising source of various high value bioproducts, and develo** cultivation processes...

Biological water quality of an impaired tropical river: the macrozoobenthos approach
Human activities are major drivers of water quality degradation, especially in densely populated cities. The water quality of the Ona River in...

Into the Intimacy of Corals, Builders of the Sea
Belonging to the very diverse cnidarian phylum, reef-building and non-reef-building scleractinian corals have an astonishing biology to respond to...

Acclimatization of a coral-dinoflagellate mutualism at a CO2 vent
Ocean acidification caused by shifts in ocean carbonate chemistry resulting from increased atmospheric CO 2 concentrations is threatening many...

Sea Surface Temperature and Phytoplankton Abundance as Crucial Proxies for Green Noctiluca Bloom Monitoring in the Northeastern Arabian Sea: A Case Study
Green Noctiluca scintillans ( NS G) is a mixotrophic dinoflagellate that frequently forms intense blooms in the north Indian Ocean, especially in the...
-
Comparative and phylogenetic analyses of Loranthaceae plastomes provide insights into the evolutionary trajectories of plastome degradation in hemiparasitic plants
BackgroundThe lifestyle transition from autotrophy to heterotrophy often leads to extensive degradation of plastomes in parasitic plants, while the...

Nutrient availability regulates the microbial biomass structure in marine oligotrophic waters
In oligotrophic oceans, trophic transfer at the base of pelagic food webs is driven by shifts in biomass ratios of plankton microbial groups, which...
-
Differing growth responses in four related microalgal genera grown under autotrophic, mixotrophic and heterotrophic conditions
Microalgae are increasingly recognised as valuable feedstock for novel product production and biotechnological applications, but high costs...
-
Harnessing solar power: photoautotrophy supplements the diet of a low-light dwelling sponge
The ability of organisms to combine autotrophy and heterotrophy gives rise to one of the most successful nutritional strategies on Earth: mixotrophy....

Fatty acid profiles of separated host–symbiont fractions from five symbiotic corals: applications of chemotaxonomic and trophic biomarkers
Fatty acids (FAs) are the main components of lipids in corals. We examined FAs profiles from five symbiotic coral species belonging to five different...

Calculation of All Possible Stoichiometric Coefficients and Theoretical Yields of Microbial Global Reactions
Stoichiometric analysis is a crucial step in biochemical processes because it allows us to find the proportions in which the substrates and products...

Seasonal Carbon Dynamics in a Temperate Lagoonal Estuary: New River, NC, USA
Estuaries act as conduits for and modifiers of carbon delivery from watersheds to the coastal ocean. Here we hypothesize that a long residence time...
-
Physiological seasonality in the symbiont and host of the northern star coral, Astrangia poculata
Assessing physiological responses that correspond to the normal range of seasonal variation can provide a better understanding of how environmental...
-
Local eukaryotic and bacterial stream community assembly is shaped by regional land use effects
With anticipated expansion of agricultural areas for food production and increasing intensity of pressures stemming from land-use, it is critical to...
-
A multi-year analysis of factors affecting ecosystem metabolism in forested and meadow reaches of a Piedmont stream
Studies of stream ecosystem metabolism over decades are rare and focused on responses to a single factor, e.g., nutrient reduction or storms....

Fresh terrestrial detritus fuels both heterotrophic and autotrophic activities in the planktonic food web of a tropical reservoir: a mesocosm study
Inland aquatic ecosystems play an important role in the global carbon cycle as they actively mineralize large amounts of terrestrial organic matter....
