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

open access: yesAquaculture, 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 ...

Effects of different types of fertilizers on plankton productivity in earthen ponds [PDF]

open access: yes, 2003
Three fertilizer types (NPK, Super-phosphate and cow dung) were applied at two levels (Low, 0.3 kg/25m super(2)/2weeks and High, 0.7kg/25 m super(2)/2weeks) to 12 ponds with two ponds serving as control.

The dominance of desmids in tropical monomictic lakes (SE Brazil) [PDF]

open access: yes, 2013
Disturbance is a concept used to explain the structure of communities. This concept emphasizes the effects of disturbance on the "break" of biomass stability in stable environments and the opportunities for the development of other species.

Broad‐range necrophytophagy in the flagellate Orciraptor agilis (Viridiraptoridae, Cercozoa) and the underappreciated role of scavenging among protists

open access: yesJournal of Eukaryotic Microbiology, Volume 72, Issue 2, March/April 2025.
Abstract Protists show diverse lifestyles and fulfill important ecological roles as primary producers, predators, symbionts, and parasites. The degradation of dead microbial biomass, instead, is mainly attributed to bacteria and fungi, while necrophagy by protists remains poorly recognized.

A New Dawn for Protist Biogeography

open access: yesGlobal Ecology and Biogeography, Volume 33, Issue 12, December 2024.
ABSTRACT Aim Biogeographers have believed for a long time that the geographical distributions of protists are only determined by environmental conditions, because dispersal is not limited. During the past two decades, the field has come a long way to show that historical and spatial factors also significantly contribute to shaping protist distributions,

Novas ocorrências de desmídias filamentosas (Desmidiaceae, Zygnematophyceae) para o estado da Bahia, Brasil New records of filamentous desmids (Desmidiaceae, Zygnematophyceae) from Bahia state, Brazil

open access: yesActa Botânica Brasílica, 2010
As desmídias de hábito filamentos são constituídas por filamentos de células relativamente curtos, que se dissociam com certa facilidade. O conhecimento destas algas no estado da Bahia é bastante escasso, até o momento, estando restrito a 13 táxons.
