Diazotroph-Derived Nitrogen Assimilation Strategies Differ by Scleractinian Coral Species
Reef-building corals generally thrive in nutrient-poor tropical waters, where among other elements, nitrogen (N) availability often limits primary productivity.

Ingestion of Diazotrophs Makes Corals More Resistant to Heat Stress
Over the past decade, coral bleaching events have continued to recur and intensify. During bleaching, corals expel millions of their symbionts, depriving the host from its main food source.

Vestigial Plastids in Parasitic Plants: Evolutionary Remnants or Adaptive Innovations? [PDF]
ABSTRACT Throughout the evolutionary history of plants, chloroplasts originating from a cyanobacterial endosymbiosis have undergone remarkable adaptation and specialization, giving rise to a multitude of plastid types. The evolution toward parasitism in plants represents a particularly extreme case of such specialization.

SUMMARY: Forty-two bacteria-free cultures of pennate diatoms from fresh water or soil were tested for ability to grow heterotrophically with glucose as the sole carbon source. Thirteen of these isolates proved capable of growth under these conditions.

Crenarchaeal heterotrophy in salt marsh sediments [PDF]
Abstract Mesophilic Crenarchaeota (also known as Thaumarchaeota) are ubiquitous and abundant in marine habitats. However, very little is known about their metabolic function in situ. In this study, salt marsh sediments from New Jersey were screened via stable isotope probing (SIP) for heterotrophy by amending with a single 13C-labeled ...

Energetics and Application of Heterotrophy in Acetogenic Bacteria [PDF]
ABSTRACTAcetogenic bacteria are a diverse group of strictly anaerobic bacteria that utilize the Wood-Ljungdahl pathway for CO2fixation and energy conservation. These microorganisms play an important part in the global carbon cycle and are a key component of the anaerobic food web.

Impact of winter ocean warming and reduced heterotrophy on the physiological response of the temperate coral Oculina arbuscula [PDF]
Increasing sea surface temperatures from anthropogenic climate change cause significant stress to marine organisms. A plethora of studies have examined the response of corals to thermal stress under controlled laboratory conditions, which often led to ...

Coupling spatiotemporal community assembly processes to changes in microbial metabolism
Community assembly processes generate shifts in species abundances that influence ecosystem cycling of carbon and nutrients, yet our understanding of assembly remains largely separate from ecosystem-level functioning.

Proteomes of an oxygenic photosynthetic cyanobacterium, Synechocystis sp. PCC 6803, were analyzed under photoautotrophic (low and high CO2, assigned as ATLC and ATHC), photomixotrophic (MT), and light-activated heterotrophic (LAH) conditions.
