Methodological tests of a heterotrophy index for aquatic ecosystems [PDF]

Brazilian Journal of Biology, 2003
Experiments in glucose mineralization were carried out to investigate the effects caused by natural forcing functions on both the decomposition rates and heterotrophy capacity of aquatic ecosystems. In addition, the methodology used could show connections between mineralization rates measured in both laboratory and field work with those measured in ...

Spontaneous evolution of heterotrophy in cultured dinoflagellate algae

Current Biology
Acquisition of chloroplasts by an early eukaryote and their subsequent spread across eukaryotes is well understood. However, evolution can be undone, and many important lineages (especially in the Apicomplexa) have lost photosynthesis, returning to heterotrophy.

Resource partitioning of phytoplankton metabolites that support bacterial heterotrophy [PDF]

The ISME Journal, 2020
Abstract The communities of bacteria that assemble around marine microphytoplankton are predictably dominated by Rhodobacterales, Flavobacteriales, and families within the Gammaproteobacteria. Yet whether this consistent ecological pattern reflects the result of resource-based niche partitioning or resource competition requires better ...

Selective nutrient incorporation may underestimate heterotrophy of a mixotrophic reef-building coral. [PDF]

Commun Biol
Mixotrophic reef-building corals acquire nutrition via photosynthate translocation from endosymbiotic microalgae and by heterotrophic prey/particle capture.

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

, 2021
Climate change-induced glacial melt affects benthic ecosystems along the West Antarctic Peninsula, but current understanding of the effects on benthic primary production and respiration is limited.

Myco-heterotrophy: when fungi host plants [PDF]

Annals of Botany, 2009
Myco-heterotrophic plants are partly or entirely non-photosynthetic plants that obtain energy and nutrients from fungi. These plants form a symbiosis with arbuscular mycorrhizal, ectomycorrhizal or saprotrophic fungi to meet their nutrient demands.This Botanical Briefing summarizes current knowledge about myco-heterotrophy, discusses its controversial ...

Net heterotrophy in High Arctic first-year and multi-year spring sea ice [PDF]

, 2022
The net productivity of sea ice is determined by the physical and geochemical characteristics of the ice–ocean system and the activity of organisms inhabiting the ice.

Evolution of heterotrophy in chrysophytes as reflected by comparative transcriptomics [PDF]

FEMS Microbiology Ecology, 2018
Shifts in the nutritional mode between phototrophy, mixotrophy and heterotrophy are a widespread phenomenon in the evolution of eukaryotic diversity. The transition between nutritional modes is particularly pronounced in chrysophytes and occurred independently several times through parallel evolution. Thus, chrysophytes provide a unique opportunity for

Impact of winter ocean warming and reduced heterotrophy on the physiological response of the temperate coral Oculina arbuscula

, 2021
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 ...
