Green‐lighting biofuels from microalgal lipids: A review of strategies to integrate stress into continuous cultures

Biofuels, Bioproducts and Biorefining, EarlyView.
Abstract The vision of using microalgae to obtain organic chemicals in a carbon‐neutral manner is intriguing. It promises to produce various substances including biofuels by photosynthesis, without competing with agricultural land. Processes have been established whereby microalgae undergo a growth phase followed by a stress phase, which induces lipid ...

Nitrogen Fixation Aligns with nifH Abundance and Expression in Two Coral Trophic Functional Groups

Frontiers in Microbiology, 2017
Microbial nitrogen fixation (diazotrophy) is a functional trait widely associated with tropical reef-building (scleractinian) corals. While the integral role of nitrogen fixation in coral nutrient dynamics is recognized, its ecological significance ...

Mesophotic corals in Hawai'i maintain autotrophy to survive low-light conditions. [PDF]

Proc Biol Sci
In mesophotic coral ecosystems, reef-building corals and their photosynthetic symbionts can survive with less than 1% of surface irradiance. How depth-specialist corals rely upon autotrophically and heterotrophically derived energy sources across the mesophotic zone remains unclear. We analysed the stable carbon (

Mycorrhizal associations and trophic modes in coexisting orchids: an ecological continuum between auto- and mixotrophy [PDF]

, 2017
Two distinct nutritional syndromes have been described in temperate green orchids. Most orchids form mycorrhizas with rhizoctonia fungi and are considered autotrophic.

Seasonal variations in planktonic food web structure affect stability by shifting the distribution of energy fluxes

Oikos, EarlyView.
Seasonality in temperate ecosystems shapes species phenology, influencing interactions and food web structure. Variations in species richness and biomass affect trophic interaction strength, a crucial factor for community stability, which can be assessed through energy fluxes – an essential indicator of ecosystem function.

Drivers of phenological transitions in the seedling life stage

Functional Ecology, EarlyView.
Read the free Plain Language Summary for this article on the Journal blog. Abstract Plant functional ecology research has primarily focused on juvenile and adult plants even though regeneration from seed can be the most consequential life‐history bottleneck with cascading influence on later stages of growth and reproduction.

Stoichiometries of remineralisation and denitrification in global biogeochemical ocean models [PDF]

, 2009
Since the seminal paper of Redfield (1934), constant stoichiometric elemental ratios linking biotic carbon and nutrient fluxes are often assumed in marine biogeochemistry, and especially in coupled biogeochemical circulation models, to couple the global ...

Prevalence of Autotrophy in Non-humic African Lakes

Ecosystems, 2022
Heterotrophic respiration of organic matter (OM) is thought to dominate over aquatic primary production (PP) in most freshwater lake ecosystems. This paradigm implies that lateral transport of OM from the terrestrial biosphere subsidize the major fraction of aquatic respiration and that many lakes are a net source of carbon dioxide (CO2) to atmosphere.

Genome and Single‐Cell Transcriptome Reveal the Evolution of Holoparasitic Plants: A Case Study of Cistanche deserticola

Plant Biotechnology Journal, EarlyView.
ABSTRACT The Orobanchaceae family, the largest group of parasitic plants, spans a complete spectrum from autotrophic to holoparasitic species. As a typical endangered holoparasitic species within this family, Cistanche deserticola is a parasitic plant that is widely harvested for traditional medicine in desertic regions, and of growing importance as a ...
