Arctic Lake Metabolism in Late Winter

Water Resources Research, Volume 62, Issue 10, October 2026.
Abstract Seasonally ice‐covered Arctic lakes experience pronounced changes in physical and biogeochemical dynamics during late winter, when increasing solar radiation initiates under‐ice primary production and convective mixing. Here we analyze high‐frequency observations of temperature, dissolved oxygen (DO), and photosynthetically active radiation ...

Chlorophyll fluorescence in micropropagated Rhododendron ponticum subsp. baeticum plants in response to different irradiances

Biologia Plantarum, 2010
The aim of this study was to investigate acclimation of micropropagated plants of Rhododendron ponticum subsp. baeticum to different irradiances and recovery after exposure to high irradiance. Plants grown under high (HL) or intermediate (IL) irradiances

Resource Recovery From Food Processing Wastewater Through Microalgae‐Driven Carbon Chain Rearrangement

GCB Bioenergy, Volume 18, Issue 10, October 2026.
Carbon chain rearrangement reframes food‐processing wastewater treatment from COD removal to controlled carbon recovery. By coupling microalgal biosynthesis with bacterial substrate transformation, algal–bacterial consortia can redirect heterogeneous wastewater carbon toward recoverable biomolecules.

Data_Sheet_1_Growth Light Environment Changes the Sensitivity of Photosystem I Photoinhibition Depending on Common Wheat Cultivars.pdf

, 2019
Light is an important factor for determining photosynthetic performance in land plants. At high light intensity, land plants develop photosynthetic activity by increasing electron sinks, such as the Calvin cycle and photorespiration and photoprotective ...

Improved primary production and gross respiration measurements using the H218O technique with membrane inlet mass spectrometry and introduction of a small volume–uniform irradiance incubation chamber

Journal of Phycology, Volume 62, Issue 5, Page 1440-1450, October 2026.
Abstract An improvement in the H218O technique for phytoplankton gross primary productivity (GPP), net primary productivity (NPP), and gross respiration (GR) is described that reduces cost, labor, and time over the traditional isotope ratio mass spectrometer (IRMS) method.

Photoinhibition of photosystem I under high light in the shade-established tropical tree species Psychotria rubra

Frontiers in Plant Science, 2015
The photosynthetic sensitivity to high light differs among understory plants of shade- and sun- established tree species. Shade-established tree species are sensitive to high light but the underlying photosynthetic mechanism has not been fully resolved ...

Linking biosurface reactivity and photosynthesis to investigate Sphagnum mosses as ecosystem engineers

New Phytologist, Volume 252, Issue 1, Page 69-86, October 2026.
Habit photographs of field‐collected and in vitro‐cultivated (c) Sphagnum spp. used for experiments. Summary Sphagnum mosses regulate peatland carbon storage, hydrology, nutrient cycling, and ecosystem functioning. However, the links among their surface chemistry, photosynthesis, responses to submersion and pH remain poorly understood.

Photoinhibition of photosynthesis in Minquartia guianensis and Swietenia macrophylla inferred by monitoring the initial fluorescence

, 2006
We assessed the effect of the exposure to full sunlight (5, 35, and 120 min, i.e. T5, T35, and T120) on fluorescence parameters of two young tropical trees, Swietenia macrophylla, a gap-demanding species, and Minquartia guianensis, a shade tolerant ...

The Long-Term Changes in Midday Photoinhibition in Rice (Oryza sativa L.) Growing under Fluctuating Soil Water Conditions

Plant Production Science, 2013
Rice crops growing under fluctuating soil water conditions in a rainfed field frequently experience severe photoinhibition at midday, potentially decreasing their biomass production.

Thermal Safety Margins and Peak Leaf Temperatures Predict Vulnerability of Diverse Plant Species to an Experimental Heatwave

Plant, Cell &Environment, Volume 49, Issue 10, Page 7526-7538, October 2026.
ABSTRACT Extreme heat can push plants beyond their thermal safety margin (TSM) if maximum leaf temperature (Tleaf_max) exceeds leaf critical temperature (Tcrit). The TSM is potentially useful for assessing heat vulnerability across species but needs further validation, so we exposed 50 tree/shrub species in controlled glasshouses to a 6‐day heatwave ...
