Diversity and toxin content of cyanobacteria in fish ponds (South Moravia, Czech Republic) related to fishery management intensity

Acta Universitatis Agriculturae et Silviculturae Mendelianae Brunensis, 2008
During the vegetative period of the year 2005 (June–October) we carried out hydrobiological and hydrochemical monitoring of selected ponds inhered in Southern Moravia in relation to different fi­she­ry management intensities. Water temperature, dissolved

Crocosphaera watsonii – A widespread nitrogen‐fixing unicellular marine cyanobacterium

Journal of Phycology, Volume 60, Issue 3, Page 604-620, June 2024.
Abstract Crocosphaera watsonii is a unicellular N2‐fixing (diazotrophic) cyanobacterium observed in tropical and subtropical oligotrophic oceans. As a diazotroph, it can be a source of bioavailable nitrogen (N) to the microbial community in N‐limited environments, and this may fuel primary production in the regions where it occurs.

Impacts of a century of land‐use change on the eutrophication of large, shallow, prairie Lake Manitoba in relation to adjacent Lake Winnipeg (Manitoba, Canada)

Freshwater Biology, Volume 69, Issue 1, Page 47-63, January 2024.
Abstract Evaluation of large lake response to centennial changes in land use and climate can be complicated by high spatial and hydrological complexity within their catchments, particularly in regions of low relief. Furthermore, large lakes can exhibit abrupt changes in structure and function that obscure causes of eutrophication.

Influence of Environmental Factors on the Dynamics and Toxicology of Microcystis and Anabaena in Eutrophic Ponds

Aquaculture Research, Volume 2024, Issue 1, 2024.
Blooms of Microcystis are common in fish ponds in Bangladesh which vary distinctly with season to season. A study on the seasonal changes of Microcystis and Anabaena was carried out over a period of 12 months from March 2021 to February 2022 in two rural fish ponds to see the effect of environmental factors on the seasonal dynamics of these two species.

[Preventive Effects of Aphanothece sacrum on Diabetic Cataracts].

Yakugaku zasshi : Journal of the Pharmaceutical Society of Japan, 2019
Approximately 20% of diabetic patients develop diabetic cataracts. As lens proteins are known to be only slightly metabolized during the lifetime, cataracts are difficult to recover from once they have progressed. Therefore, the daily intake of natural compounds would be an important strategy for the prevention of diabetic cataracts. Aphanothece sacrum
