The Genus Cladophora Kützing (Ulvophyceae) as a Globally Distributed Ecological Engineer

Area of Science:

• Marine biology
• Freshwater ecology
• Phycology

Background:

• The green algal genus Cladophora forms significant nearshore populations globally.
• Cladophora-dominated periphyton can cause nuisance blooms due to nutrient pollution.
• This alga is recognized as an ecological engineer, fostering benthic microfauna diversity.

Purpose of the Study:

• To review literature on Cladophora's taxonomy, cell biology, morphology, reproduction, and ecology.
• To examine how Cladophora modifies habitats and influences littoral biogeochemistry.
• To explore its role in supporting epiphytes and potential technological applications.

Main Methods:

• Literature review of classic and recent studies.
• Analysis of Cladophora's ecological functions and habitat modification.
• Examination of its role in biogeochemical cycling and potential applications.

Main Results:

• Cladophora supports diverse microalgal and bacterial epiphytes, influencing carbon and element cycling.
• Its complex structure fosters functional and taxonomic diversity of benthic microfauna.
• High production of cellulose and hydrocarbons offers potential for wastewater remediation and biofuel production.

Conclusions:

• Cladophora's morphology (stable holdfasts, branched architecture, large cells, robust walls) contributes to its ecological engineering roles.
• The alga significantly influences littoral biogeochemistry and benthic communities.
• Cladophora presents opportunities for technological applications in bioremediation and renewable energy.
