Anecdotal
|
N/A
|
In recent years, large blooms (over 1 million tons) of Ulva prolifera have lead to declines in seagrass beds due to shading, disruption of feeding by wading birds, and an overall loss of algal biodiversity.

|
Ulva prolifera mats that formed on intertidal sandflats in Scotland were found to significantly decrease the macrofaunal diversity. These negative impacts were particularly on species that use planktonic larval recruitment.

U. prolifera was able to outcompete Blidingia sp. on Pyropia culture rafts in China as the season
progressed; seasonal physiological shifts and relative buoyancy were responsible for the
competitive advantage.
