Alaska Aquatic Plant Survey Report, 2005.

摘要

Invasive, non-indigenous plants can degrade water quality and fish habitat when they invade lakes, ponds, and streams. Changes in plant community architecture in lakes due to invasion by canopy-forming invasive aquatic plants can result in loss of native plant biodiversity and reduction of the structural complexity of the underwater habitat. Differences in photosynthetic biochemistry between nonindigenous and native plants can result in large diurnal pH and dissolved oxygen concentrations. In Alaska, because of the prevalence of floatplanes as a means of transport, invasive aquatic plants could also present a risk to human life and property.
