Definition of African Elodea
African Elodea, scientifically known as Lagarosiphon Major, is an integral aquatic plant predominantly found in afro-tropical locations. Often referred to as the “Oxygen Plant”, it is renowned for its oxygenating attributes and its usage in the aquascaping community.
The Basic Description of African Elodea
African Elodea is an impressive aquatic plant identified by its green hue and its intriguingly crystalline and curly leaves. It is predominantly submerged, meaning that the majority of its growth pattern is underwater, distinguishing it from other water plants that float or grow along the surface. The African Elodea has an incredibly unique ability to make use of sunlight while submerged, building towards its reputation as an oxygen factory.
Scientific Classification of African Elodea
In the grand scheme of the Plant Kingdom, the African Elodea belongs to the family Hydrocharitaceae. Delving into its biological classification, one will find that from the order Alismatales, it resides within the class Liliopsida, falling under the phylum Tracheophyta.
Physical Characteristics
The African Elodea’s physical makeup is easy to identify, due to its distinct characteristics.
Growth Pattern of the Plant
African Elodea is able to grow up to five meters lengthwise, enveloping the underwater area it occupies. Its ability to grow depth-wise is equally impressive, being able to extend up to three meters underground.
Description of Leaves
The leaves of African Elodea are a sight to behold, appearing to twirl and curl underwater. These rather unique leaf form is typically arranged in a whirl of three around the stem, with a dark, glossy green shade.
Properties of the Stem
The stem of the African Elodea is robust and very stiff, and can grow up to 3mm thick. It usually displays a bright green shade and can grow quite long, depending upon the water body.
Details about Flowering and Fruiting
The production of flowers for African Elodea is somewhat unusual. The plant sprouts whitish flowers that emerge mainly during summer and early autumn. However, they rarely bloom. Instead, the plant primarily reproduces asexually.
Habitat Requirements
The African Elodea has specific habitat requirements in order to grow and flourish optimally.
Preferred Water Conditions
The plant thrives well in slow-moving or still water bodies, such as ponds, slow rivers, dams, and lakes. It also prefers water temperatures that fall between 10 – 25 degrees Celsius for ideal growth potential.
Soil Necessities
The African Elodea is tolerant of various soil types but tends to thrive best in those that foster good nutrient exchanges, such as muddy substrates found in pond bottoms and river banks.
Geographic Distribution
African Elodea is native to certain parts of the world, while being introduced to others for ecological and aquascaping purposes.
Native Regions
It is native to parts of Africa, predominantly the subtropical and tropical regions. These areas serve as the natural habitat for the African Elodea.
Introduced and Naturalized Areas
Owing to its attractive physical characteristics, the African Elodea has become popular within the aquascaping community, and has been introduced in several places across the globe, including parts of Australia, Europe, and the United States.
Propagation Mechanisms
African Elodea has two primary means of propagation; sexual and asexual reproduction.
Sexual Reproduction
The African Elodea rarely undergoes sexual reproduction, which involves the production of seeds through its rarely flowering components.
Asexual Reproduction via Fragmentation
Its primary reproductive mode is asexual reproduction, achieved through fragmentation. This mechanism allows the plant to form new individuals from fragmentation of the stem, often occurring during accidental breaks or human interference.
Role in the Ecosystem
The African Elodea, due to its robust growth, plays a critical role in the aquatic ecosystem.
Role as a Primary Producer
As a photosynthetic plant, African Elodea serves as a primary producer within the underwater ecosystem, producing oxygen and converting sunlight into food.
Ecological Interactions with Animals
The plant creates an excellent habitat and refuge for various aquatic species, acting as a breeding ground for many. It is also a prominent food source for certain herbivorous underwater species.
Influence on the Water Quality
African Elodea helps maintain the quality of aquatic ecosystems. They act as biofilters, absorbing excess nutrients from the water, hence thwarting the growth of harmful algae blooms.
Use in Aquascaping
The African Elodea finds extensive use in aquariums due to its beneficial traits.
Benefits for Aquarium Environments
The plant is excellent for oxygenating water, enhancing its quality, and creating a visually appealing green space. Its dense growth aids in creating hiding spots for fishes, enhancing the biodiversity of the aquarium as well.
Maintenance Requirements in Aquariums
African Elodea’s robust growth requires regular trimming. However, they are generally easy to manage owing to their simple requirements of ample light, and average water temperature, needing no additional supplements or fertilizers.
Potential Threats to African Elodea
Despite its strong growth, African Elodea still fights threat from diseases, parasites, and adverse environmental conditions.
Common Diseases
African Elodea mainly suffers from diseases related to poor water quality. Changes in water composition, leading to reduction in light penetration, can cause the plant to discolor and stunt its growth.
Typical Parasites and Pests
There are no specific pests or parasites that mainly target African Elodea, but general aquatic pests could potentially harm the plant.
Environmental Threats
Changes in the water body, alteration in temperature, pollution and draining of water bodies for agricultural use pose a major threat to the plant.
Management and Control Measures
When introduced outside its native region, it’s necessary that this plant’s growth is carefully managed to prevent it from becoming invasive.
Physical Control Methods
The extraction of the entire plant including roots is a common method used to control its proliferation, usually done manually or using machinery.
Chemical Control Methods
Herbicides are sometimes used to control their growth, although with restrained usage to prevent water pollution.
Biological Control Measures
Certain species of moth, and weevil are identified as potential biocontrol agents against African Elodea.
Research on African Elodea
The African Elodea has sparked various research interests owing to its unique characteristics and ecological roles.
Recent Scientific Studies
Recent studies have focused on understanding the plant’s oxygenating attributes, its physiochemical properties, and determining its better control measures when it becomes invasive.
Unresolved Questions in the Research
However, the precise ecological implications of the African Elodea in non-native regions and the long-term effects of its extensive propagation are questions that still demand answers. Further research in these areas could potentially offer more insights into these crucial aspects.
