Experimental Assessment of Epipelon Responses to Phosphorus Limitation in a Eutrophic Lake

Ecological Research, Volume 41, Issue 6, November 2026.
We evaluated the responses of epipelic algal and cyanobacterial communities to increasing phosphorus limitation in the water column under eutrophic conditions. Nitrogen enrichment increased the N:P ratio and intensified phosphorus limitation in the water column, promoting changes in community composition. The greater contribution of cyanobacteria (e.g.,

Solutions for managing cyanobacterial blooms: A scientific summary for policy makers.

, 2019
Algae grow wherever there is water; in oceans, freshwater lakes, rivers, streams and pools. They underpin aquatic food webs, providing nutrition for animals in the system, and along with microbes, are responsible for cycling energy and nutrients throughout the environment.

Biosorption of Copper by Cyanobacterial Bloom-Derived Biomass Harvested from the Eutrophic Lake Dianchi in China

, 2010
Biomass of cyanobacterial bloom from Lake Dianchi was used as a biosorbent for copper removal from aqueous solution. The maximum capacity was found at conditions of pH 4, initial concentration of copper was 10 mg/l and initial dose of biomass was 1.0 g/l.

Microeukaryotic Diversity and Habitat Structuring in a Desiccating Alkaline Maar Lake (Central Mexico)

Journal of Eukaryotic Microbiology, Volume 73, Issue 6, November/December 2026.
ABSTRACT Microeukaryotes are important components of microbial food webs in saline and alkaline lakes, yet their diversity and distribution across distinct microhabitats remain poorly understood. We characterized microeukaryotic communities associated with microbialites, microbial mats, hypersaline waters, and sediments in the desiccating maar lake ...

Melanoma and Other Melanistic Lesions in Brown Bullhead Ameiurus nebulosus From Waterbodies in the Northeastern United States and Canada: Identification of Risk Factors

Journal of Fish Diseases, Volume 49, Issue 11, November 2026.
ABSTRACT Melanistic lesions, including non‐raised black areas due to proliferations of melanocytes and melanomacrophages in the dermis and epidermis, as well as raised black areas consistent with melanoma, are described in brown bullhead (BBH) Ameiurus nebulosus from three water bodies in the northeastern United States and Quebec, Canada.

Cyanobacterial Blooms and the Presence of Cyanotoxins in the Brazilian Amazon

Toxins
The records of blooms and cyanotoxins in the Brazilian Legal Amazon are scarce and do not represent the reality observed in recent years when there was an increase in notifications and studies carried out in this region. In this article, we carefully analyzed 48 studies to identify the locations where the blooms occurred, the most frequent species, and

Cyanobacterial blooms and animals [PDF]

Cyanobacteria (also called blue-green algae) are microscopic organisms that can be found naturally in all types of water (fresh; marine; or a combination, which is also called brackish).

Detection of microcystins in Pamvotis lake water and assessment of cyanobacterial bloom toxicity

, 2012
Lake Pamvotis is a shallow, eutrophic Mediterranean lake with ecological significance. This paper deals with the evaluation of cyanobacterial toxicity in Lake Pamvotis. ELISA and HPLC revealed the presence of significant amounts of MCYST-LR.
