N/A
|
Limnoperna fortunei actively transfers organic matter from the pelagic to the benthic zones and enriches sediment through their filtration and production of pseudofeces.

|
Limnoperna fortunei filter feeding of organic matter will clarify the water and increase light penetration. These changes may alter the thermal regime and increase primary production.

In microcosm experiments, Limnoperna fortunei changed the nutrient content in the water column in such a way that could favor the development of certain phytoplankton groups over others. This could also inadvertently select for faster growing phytoplankton and increase their abundance.

In the Río de la Plata estuary, Limnoperna fortunei doubles the rate of sedimentation for suspended particles and increases their organic matter and nitrogen contents. These changes are expected to increase accretion rates and alter the communities that occupy the sediments.

Limnoperna fortunei alters nutrient concentrations and supports the aggregation of isolated Microcystis spp. cells into colonies, both of these effects support blooms of this cyanobacteria.

Results of mesocosm experiments found that Limnoperna fortunei removed 84% of the particulate nitrogen and 49% of the particulate phosphorus after 24 hours. Nutrient regeneration was influenced by L. fortunei as well with ammonium produced at 3 µM NH3g DW-1 h-1 and phosphates produced at 0.42 µM PO4g DW-1 h-1.

N/A
|
The shell production by Limnoperna fortunei decreases flow velocity, increases shear strength and increases sedimentation. This directly supports infauna abundance and indirectly increases omnivorous fish abundance as well as interference competition with native bivalves, reed roots, etc..
