Fungal-colonized leaves and pure mycelia of fungi common on standing-dead leaves allowed intermediate growth. However, that paradigm has been challenged by investigations showing that grazing by the periwinkle snail Littoraria irrorata regulates Spartina alterniflora growth through top-down forces. L. irrorata also deposits faeces on the wounds that they create, which encourage the growth of the fungi because they are rich in nitrogen and fungal hyphae. In surveys conducted along 2,000 kilometers of salt marshes on the southern U.S. shoreline, the researchers observed that the snail, Littoraria irrorata, actively grazes a live salt-marsh cordgrass.

Periwinkles are likely to be important controlling agents of fungal standing crops and important shapers of fungal community dynamics in cordgrass marshes, in that the standing, decaying substratum for fungal growth and the potential for fungal species successions are radically changed by the snails' activities. Littoraria irrorata AquaMaps Data sources: GBIF OBIS: Upload your photos Google image | No photo available for this species. When grazing live marsh grass, Littoraria create and maintain wounds on leaf blades with their radulae, and the opening of live plant tissue results in microbial invasion, significantly increasing … & F.
