Using Stable Isotope Analyses to Assess the Trophic Ecology of Scleractinian Corals

open access: yesOceans, 2022
Studies on the trophic ecology of scleractinian corals often include stable isotope analyses of tissue and symbiont carbon and nitrogen. These approaches have provided critical insights into the trophic sources and sinks that are essential to ...

Natural Polyhydroxyalkanoates—An Overview of Bacterial Production Methods

open access: yesMolecules
Polyhydroxyalkanoates (PHAs) are intracellular biopolymers that microorganisms use for energy and carbon storage. They are mechanically similar to petrochemical plastics when chemically extracted, but are completely biodegradable.

Modest net autotrophy in the oligotrophic ocean [PDF]

open access: yesGlobal Biogeochemical Cycles, 2017
AbstractThe metabolic state of the oligotrophic subtropical ocean has long been debated. Net community production (NCP) represents the balance of autotrophic carbon fixation with heterotrophic respiration. Many in vitro NCP estimates based on oxygen incubation methods and the corresponding scaling relationships used to predict the ecosystem metabolic ...

Evolution of plant reproduction: from fusion and dispersal to interaction and communication [PDF]

open access: yes, 2009
Based on the existing data concerning the evolution of the sexual reproduction, it is argued that the processes of sex differentiation and interactions play a key role in evolution. From the beginning environment and organism are unified.

Microbial autotrophy explains large‐scale soil CO2 fixation

open access: yesGlobal Change Biology, 2022
AbstractMicrobial communities play critical roles in fixing carbon from the atmosphere and fixing it in the soils. However, the large‐scale variations and drivers of these microbial communities remain poorly understood. Here, we conducted a large‐scale survey across China and found that soil autotrophic organisms are critical for explaining CO2 fluxes ...

Dissection of Microbial Community Functions during a Cyanobacterial Bloom in the Baltic Sea via Metatranscriptomics

open access: yesFrontiers in Marine Science, 2018
Marine and brackish surface waters are highly dynamic habitats that undergo repeated seasonal variations in microbial community composition and function throughout time.

Glacial melt disturbance shifts community metabolism of an Antarctic seafloor ecosystem from net autotrophy to heterotrophy

open access: yesCommunications Biology, 2021
Ulrike Braeckman et al. use in situ benthic community and benthic biogeochemistry measurements in Potter Cove on the Antarctic Peninsula to show that climate-related glacial melt disturbance shifts benthic communities from net autotrophy to heterotrophy.

Seabird-Derived Nutrients Supply Modulates the Trophic Strategies of Mixotrophic Corals

open access: yesFrontiers in Marine Science, 2022
The ability of corals to modulate their nutrition strategy in response to variable nutrient supply remains poorly understood, limiting our understanding of energy flow in coral reef ecosystems and thus our comprehension of their resilience to global ...

The compositional and evolutionary logic of metabolism

open access: yes, 2012
Metabolism displays striking and robust regularities in the forms of modularity and hierarchy, whose composition may be compactly described. This renders metabolic architecture comprehensible as a system, and suggests the order in which layers of that ...
