The Phosphorus Cycle

The Phosphorus Cycle

Unlike carbon, water, and nitrogen, phosphorus is not present in the atmosphere as a gas. Instead, most phosphorus in the ecosystem exists as compounds, such as phosphate ions (PO43-), found in soil, water, sediment and rocks. Phosphorus is often a limiting nutrient (i.e., in short supply). Consequently, phosphorus is added to most agricultural fertilizers, which can cause environmental problems related to runoff in aquatic ecosystems.

Comparing Mitochondrial, Chloroplast, and Prokaryotic Genomes

Comparing Mitochondrial, Chloroplast, and Prokaryotic Genomes

The present-day mitochondrial and chloroplast genomes have retained some of the characteristics of their ancestral prokaryotes and also have acquired new attributes during their evolution within eukaryotic cells. Like prokaryotic genomes, mitochondrial and chloroplast genomes neither bind with histone-like proteins nor show complex packaging into chromosome-like structures, as observed in eukaryotes. Unlike mitotic cell divisions observed in eukaryotic cells, mitochondria and chloroplasts...

Area of Science:

Environmental Science
Ecology
Microbiology

Background:

Cyanobacteria form dense, toxic blooms in freshwater and marine ecosystems.
These blooms degrade water quality, impacting recreation, drinking water, fisheries, and human health.

Purpose of the Study:

To review evidence on the increasing frequency, magnitude, and duration of global cyanobacterial blooms.
To identify species traits and environmental conditions favoring cyanobacterial proliferation.
To discuss management strategies for bloom mitigation.

Main Methods:

Literature review of scientific evidence on cyanobacterial blooms.
Analysis of factors contributing to bloom expansion, including eutrophication and climate change.
Synthesis of current and potential management approaches.

Main Results:

Cyanobacterial blooms are increasing globally in occurrence and severity.
Eutrophication and climate change are key drivers accelerating bloom expansion.
Specific species traits and environmental conditions facilitate cyanobacterial dominance.

Conclusions:

Effective management requires integrated strategies addressing nutrient pollution and climate change.
Reducing nutrient loads is crucial for preventing and mitigating harmful cyanobacterial blooms.
Further research into biological and hydrodynamic controls may offer additional solutions.
