Boundaries of photosynthesis: adaptations of carbon fixation in extreme environments

FEBS Open Bio, Volume 15, Issue 7, Page 1028-1040, July 2025.
Photosynthesis faces challenges from environmental extremes of temperature, pH, and salinity, limiting gas diffusion, modifying membrane fluidity, and destabilizing photochemical and biochemical reactions. Photosynthetic organisms have evolved unique adaptations overcoming these stresses and maintaining their photosynthetic activity.

Nature of Phytoplankton Communities in the Southern Hemisphere Shallow Lakes, With an Emphasis on the Presence of Submerged Aquatic Vegetation: A Review

Aquaculture, Fish and Fisheries, Volume 5, Issue 3, June 2025.
ABSTRACT Differences in the ecological stability of shallow lakes are reflected in the functional nature of the distinct phytoplankton communities in the Southern Hemisphere. Recent studies have highlighted growing uncertainties of the previous concepts regarding phytoplankton cosmopolitanism, suggesting these communities may be more regionally ...

Stronger dispersal potential of alkaline phosphatase‐encoding bacteria ensures higher organic phosphorus mineralization rate

Functional Ecology, Volume 39, Issue 3, Page 756-769, March 2025.
Read the free Plain Language Summary for this article on the Journal blog. Abstract Scientific theory largely neglects linkage between organic phosphorus (Po) mineralization rate and dispersal potential of alkaline phosphatase‐encoding bacteria (PEB) containing the phoD gene. Different densities of substrates (i.e.

Effects of Changing Snow and Ice Cover Conditions on Phytoplankton Chlorophyll‐a and Community Composition in a Mesotrophic Lake

Freshwater Biology, Volume 70, Issue 3, March 2025.
ABSTRACT Ice and snow cover on lakes plays a fundamental role for under‐ice ecology by reducing water column mixing and light availability. Previous studies have shown that such reductions can significantly influence the growth and reproduction of phytoplankton, primarily focusing on changes in ice‐on and ice‐off dates in a warming climate.
