Stuck in a rut: Ocean acidification locks algal communities in a simplified state
Researchers from the University of Tsukuba have found that ocean acidification limits algal communities to a state of low diversity and complexity. Communities grown in waters rich in carbon dioxide (CO2) were dominated by turf algae, and had low biodiversity, ecological complexity and biomass. Communities grown under acidic conditions and then transferred to waters that weren't CO2-enriched increased their biodiversity and complexity, showing that they can recover if CO2 emissions are significantly reduced.

How plants compete for underground real estate affects climate change and food production
How do plant roots store carbon? Princeton researchers found that the energy a plant devotes to its roots depends on proximity to other plants: when close together, plants heavily invest in their root systems to compete for finite underground resources; if far apart, they invest less. As about a third of the world's vegetation biomass (and carbon) is belowground, this model provides a valuable tool to predict root proliferation in global earth-system models. (2020-12-03)

Residential energy use of all types led to 67% of these premature deaths overall, the findings (2020-10-28)

Shifts in flowering phases of plants due to reduced insect density
A research group of the University of Jena and the iDiv has discovered that insects have a decisive influence on the biodiversity and flowering phases of plants. If there is a lack of insects where the plants are growing, their flowering behaviour changes. This can result in the lifecycles of the insects and the flowering periods of the plants no longer coinciding. If the insects seek nectar, some plants will no longer be pollinated. (2020-10-26)

The highest heat-resistant plastic ever is developed from biomass
The use of biomass-derived plastics is one of the prime concerns to establish a sustainable society, which is incorporated as one of the Sustainable Development Goals. However, the use of most of the biomass-derived plastics is limited due to their low heat resistance. Collaborative research between JAIST and U-Tokyo has successfully developed the white-biotechnological conversion from cellulosic biomass into the aromatic polymers having the highest thermodegradation of all the plastics reported ever. (2020-10-21)

National laboratories point to sugars as a key factor in ideal feedstock for biofuels

Study first to tally biomass from oceanic plastic debris using visualization method
Scientists examined cell abundances, size, cellular carbon mass, and how photosynthetic cells differ on polymeric and glass substrates over time, exploring nanoparticle generation from plastic like polystyrene and how this might disrupt microalgae. Conservative estimates suggest that about 1 percent of microbial cells in the ocean surface microlayer inhabit plastic debris globally. This mass of cells would not exist without plastic debris in the ocean, and thus, represents a disruption of the proportions of native flora in that habitat. (2020-10-13)
