The effect of UV radiation on photosynthetic rate and carbon uptake, estimated as carbonic anhydrase activity, was studied by incubating intertidal algae, Fucus spiralis (Phaeophyta) and Ulva olivascens (Chlorophyta), under both artificial and solar ...

Experimentally derived critical thermal maxima (CTmax) are widely used to estimate species' thermal tolerance and increasingly to predict vulnerability to chronic warming. However, evidence shows how CTmax is dynamic and can be strongly influenced by multiple environmental and methodological factors, potentially limiting its application as a fixed ...

Nutritional content of phytoplankton communities under ice
Abstract The effects of winter environmental conditions on lake ecology can be highly variable. Ice and overlying snow isolate the water below, impeding exchange of materials among water, atmosphere, and the watershed. Even with these limitations, biological communities under the ice can persist, where cold‐tolerant taxa can be especially abundant ...

ABSTRACT Fluctuating light (FL), caused by cloud movement, canopy dynamics, and intercropping, is a pervasive stress affecting crop productivity, yet the molecular basis of FL responses in different photosensitivity soybeans remains poorly understood. Here, we integrated physiological, transcriptomic, and proteomic analyses to compare the responses to ...

Does photoinhibition and/or phosphorylation of photosystem II influence its in vivo oligomeric state? [PDF]
We have examined the effects of phosphorylation and photoinhibition upon grana membranes and photosystem II (PSII) by electron microscopy and single particle analysis.

Rising Indoor Wheat Yields in Vertical Farming
ABSTRACT Wheat (Triticum aestivum) is central to human nutrition but increasingly challenged by climate change and resource constraints. Vertical farming offers a potential solution through controlled, year‐round cultivation, but the upper limits of productivity remain unclear.

ABSTRACT Rising global temperatures increasingly threaten bean production and the food security of millions of people who depend on these protein‐rich legumes. Heat stress during the reproductive stages induces pollen sterility, flower abscission, and disruptions in source–sink relationships, resulting in yield losses of 30%–40% or more when critical ...

Tolerance to photoinhibition within lichen species is higher in melanised thalli
Some lichenized ascomycetes synthesize melanic pigments when exposed to ultraviolet light and high solar radiation. Here, we used chlorophyll fluorescence in order to test the effect of melanisation on the ability of the lichens Cetraria islandica ...

Higher methanotroph abundance and bottom‐water methane in ponds with floating photovoltaic arrays
Abstract Floating photovoltaic (FPV) arrays alter the methane (CH4) cycling dynamics of waterbodies on which they are deployed. Here, we investigated dissolved CH4 dynamics and associated CH4 cycling microbial communities (methanogens and methanotrophs) in the 2nd year of FPV deployment (70% aerial coverage) in experimental ponds.

Microalgae are a promising renewable feedstock that can be produced on non-arable land using seawater. Their biomass contains proteins, lipids, carbohydrates, and pigments, and can be used for various biobased products, such as food, feed, biochemicals ...
