4578 Phalaris arundinacea Habitat Alteration Experimental Laboratory Pacific chorus frogs Pseudacris regilla showed both greater breeding activity and higher tadpole survivor rates in mesocosms with the invasive Phalaris arundinacea when compared with other aquatic plants. 36490
4581 Phalaris arundinacea Habitat Alteration Observational Field Substrates in which Phalaris arundinacea stands were cultivated had increases in microbial activity and microbial biomass. Eastern Finland 36922
4582 Phalaris arundinacea Habitat Alteration Observational Field The substrate in site with Phalaris arundinacea had a higher fungi to bacteria ratio than native peat moss sites. Eastern Finland 36922
4589 Phalaris arundinacea Habitat Alteration Observational Field Phalaris arundinacea grows on waterlines, causing sediment deposition. Western United States 36927
4590 Phalaris arundinacea Habitat Alteration Observational Field Phalaris arundinacea grows into dense, monotypic stands, which increase sediment deposition and decrease the organic content in soil, changing the soil chemistry of habitats. Midwest, USA 36928
4594 Phalaris arundinacea Habitat Alteration Observational Field Insect diversity in the soil of marshes dominated by introduced Phalaris arundinacea stands were lower compared to adjacent marshes without Phalaris arundinacea. Spencer Island, Washington, USA 36495
4595 Phalaris arundinacea Habitat Alteration Observational Field Species richness was lower in beaver dam habitats when the introduced Phalaris arundinacea was present in Alsea drainage area of the Oregon Coast Range, with one species lost for every 7% increase in Phalaris arundinacea cover. Alsea Drainage, Oregon, USA 36918
4597 Phalaris arundinacea Habitat Alteration Anecdotal N/A Phalaris arundinacea outcompetes native plant species, leading to a loss of plant and insect diversity in systems in which is is introduced. 27589
4603 Phalaris arundinacea Habitat Alteration Anecdotal N/A Phalaris arundinacea alters water circulation in wetlands. North America 27590
4606 Phalaris arundinacea Habitat Alteration Observational Field Phalaris arundinacea replaced wetland plants in Portland, Oregon, creating monotopic stands and changing and dominating the canopy cover in the systems. The stands also decreased organic content and increased moisture in the soil of the area. Portland, OR, USA 36923
4607 Phalaris arundinacea Habitat Alteration Observational Field Dense stands of Phalaris arundinacea were associated with a change in the community composition of arthropods; species richness decreased where Phalaris arundinacea dominated. Portland, OR, USA 36923
4608 Phalaris arundinacea Habitat Alteration Observational Field Phalaris arundinacea provides foraging habitat as well as food to birds and small mammals. England 36921
4609 Phalaris arundinacea Habitat Alteration Experimental Field Phalaris arundinacea change the nitrogen composition of floodplains. Mississippi River Basin 36933
4610 Phalaris arundinacea Habitat Alteration Observational Field Phalaris arundinacea introduction is associated with a loss of diversity in moths. Pacific Northwest, USA 33034
4612 Phalaris arundinacea Habitat Alteration Observational Field Phalaris arundinacea alters the water use patterns of native plants, as well as water availability, in riparian areas of eastern Washington state. Eastern Washington state, USA 36493
4614 Phalaris arundinacea Habitat Alteration Observational Field Phalaris arundinacea form dense stands that replace native vegetation, which changes the food web of the riparian zones in Washington. Washington state, USA 27596
4616 Phalaris arundinacea Habitat Alteration Observational Field Phalaris arundinacea introduction changed the habitat in western Washington state, leading to the stranding death of over 150 endangered Coho salmon (Oncorhynchus kisutch). western Washington state 36935
4617 Phalaris arundinacea Habitat Alteration Experimental Laboratory Carbon and nitrogen sequestration were lower in mesocosms with introduced Phalaris arundinacea than those with only native wet prairie plant communities. 27578
