Nutrient inputs in mesocosms of an oligotrophic lake fail to sustain an algal bloom
Ecosphere, Volume 16, Issue 2, February 2025.Abstract Harmful algal blooms (HABs) rapidly change and threaten aquatic ecosystems. HABs in oligotrophic lakes are becoming more commonly observed, despite the long‐held paradigm that algal blooms cannot happen in low‐nutrient systems. This raises the question of whether nutrient loading, understood as a major driver of HABs, plays an important role ...

Mapping of protein-protein interaction sites in the plant-type [2Fe-2S] ferredoxin. [PDF]
PLoS ONE, 2011 Knowing the manner of protein-protein interactions is vital for understanding biological events. The plant-type [2Fe-2S] ferredoxin (Fd), a well-known small iron-sulfur protein with low redox potential, partitions electrons to a variety of Fd-dependent ...

Adaptive Responses of Cyanobacteria to Phosphate Limitation: A Focus on Marine Diazotrophs
Environmental Microbiology, Volume 26, Issue 12, December 2024.Marine diazotrophic cyanobacteria, which are essential for atmospheric nitrogen fixation in low‐nutrient oceans, have developed various strategies to survive under phosphate (Pi) limitation by using high‐affinity transporters and enzymes that break down dissolved organic phosphorus (DOP).

Polyphosphate phosphorus in the Great Lakes
Limnology and Oceanography Letters, Volume 9, Issue 5, Page 602-611, October 2024.Abstract Polyphosphate (polyP) is important to phytoplankton ecology, but a unified view of its variability and roles in ecosystem‐scale phosphorus (P) cycling is lacking. We study polyP in the world's largest freshwater ecosystem, the Laurentian Great Lakes, covering pelagic to nearshore areas across a wide nutrient gradient.

Limnology and Oceanography, Volume 69, Issue 9, Page 1955-1969, September 2024.Abstract Picocyanobacteria are widespread and globally significant primary producers. In brackish waters, picocyanobacterial populations are composed of diverse species with both single‐cell and colony‐forming lifestyles. Compared to their marine counterparts, brackish picocyanobacteria are less well characterized and the focus of research has been ...
