She worked on a project studying how temperature changes affect grazing in the Marsh Periwinkle, Littoraria irrorata. Periwinkles provided with marsh sediment, yellow-green, sterile, or bacteria-colonized leaves lost organic mass. Here, we examined the influence of temporal and environmental gradients on individual behavioural responses in a marine gastropod, Littoraria irrorata.

In a preliminary comparison of adjacent marsh areas of equivalent canopy height, the one without periwinkles had a 4 × greater standing crop of dead leaves. Quite the same Wikipedia. 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. The primary component of the stomach and feces was vascular plant particles. Biol. Norton, T. A., S. J. Hawkins, N. L. Manley, G. A. Williams & D. C. Watson, 1990.

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. 1983. & B. Bebout, 1986. 118: 109–114. Biol. 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. Although vegetation (mangrove bark, algae, seeds, and rhizomes) was the most frequently occurring item (84%), dry mass of this category (2.17 g) contributed only 3% of the total mass across all samples. It creates and maintains wounds on the grass, Spartina alterniflora, which are then infected by fungi, probably of the Phaeosphaeria and Mycosphaerella genera. Littoraria irrorata has been extensively studied in terms of the organisms effect on S. alterniflora productivity (Silliman and Zieman 2001, Kiehn and Morris 2009) and on the effects of the Deepwater Horizon oil spill on survivability (Zengel et al.
