Boundaries of photosynthesis: adaptations of carbon fixation in extreme environments. [PDF]

open access: yesFEBS Open Bio
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.

Population growth potential of rotifers from a high altitude eutrophic waterbody, Madín reservoir (State of Mexico, Mexico): The importance of seasonal sampling

open access: yesJournal of Limnology, 2018
To understand the population growth potential of different species of rotifers in nature, field collections through seasons are essential. We sampled zooplankton (and measured selected physicochemical variables) from the Madín reservoir, a high altitude ...

Long‐term nutrient load reductions and increasing lake TN : TP stoichiometry decrease phytoplankton biomass and diversity in a large shallow lake

open access: yesLimnology and Oceanography, Volume 68, Issue 10, Page 2389-2401, October 2023., 2023
Abstract Nutrient loading of freshwater and marine habitats has increased during the last century as a result of anthropogenic activities. From the 1980s onwards, following implementation of new policy targeting eutrophication, total phosphorus (TP) and total nitrogen (TN) loads were reduced in many European waters. Often, however, decreases in TP were

Identification of Cyanobacteria in a Eutrophic Coastal Lagoon on the Southern Baltic Coast

open access: yesFrontiers in Microbiology, 2017
Cyanobacteria are found worldwide in various habitats. Members of the picocyanobacteria genera Synechococcus and Prochlorococcus dominate in oligotrophic ocean waters. Other picocyanobacteria dominate in eutrophic fresh or brackish waters. Usually, these

Variability of asymbiotic N‐fixation organism activity with distance and time in North Dakota transitional no‐till soils

open access: yesSoil Science Society of America Journal, Volume 87, Issue 5, Page 1072-1082, September/October 2023., 2023
Abstract Asymbiotic nitrogen fixation (N‐fixation) is a microbial process that may result in the introduction of plant‐available N into the soil. Although the process of N mineralization in soils is mediated by many microorganisms and is related mostly to soil moisture, the soil factors which regulate asymbiotic N‐fixation are relatively unknown and ...
