The Deepwater Horizon (DWH) oil spill resulted in the release of millions of barrels of oil into the Gulf of Mexico, and some marsh shorelines experienced heavy oiling including vegetation laid over under the weight of oil. Periwinkle snails (Littoraria irrorata) are a critical component of these impacted habitats, and population declines following oil spills, including DWH, have been documented. This study determined the effects of oil on marsh periwinkle movement and survivorship following…

Joint Effects of Fragmentation and Mercury Contamination on Marsh Periwinkle (Littoraria irrorata) Movement
There are different ways contaminants can interact and enhance the effects of habitat fragmentation, such as modifying the movement of organisms. The present study tested the hypothesis that mercury


Impacts of the Deepwater Horizon Oil Spill on Salt Marsh Periwinkles (Littoraria irrorata).
Based on the size of adult periwinkles observed coupled with age and growth information, population recovery is projected to take several years once oiling and habitat conditions in affected areas are suitable to support normal periwinkle life-history functions.
Impacts and recovery of the Deepwater Horizon oil spill on vegetation structure and function of coastal salt marshes in the northern Gulf of Mexico.
Investigation of the impacts of the Deepwater Horizon oil spill on two dominant coastal saltmarsh plants in the northern Gulf of Mexico found that Spartina alterniflora was much more tolerant to shoot oil coverage than J. roemerianus; however, Juncus recovered to a much lesser extent.
Heavily Oiled Salt Marsh following the Deepwater Horizon Oil Spill, Ecological Comparisons of Shoreline Cleanup Treatments and Recovery
Manual treatment appeared to strike the right balance between improving oiling and habitat conditions while not causing additional detrimental effects, and even with these improvements, marsh periwinkle snails showed minimal signs of recovery through two years, suggesting that some ecosystem components may lag vegetation recovery.
Effects of oil on the rate and trajectory of Louisiana marsh shoreline erosion
Oil can have long-term detrimental effects on marsh plant health, both above- and belowground. However, there are few data available that quantify the accelerated rate of erosion that oil may cause
Degradation and resilience in Louisiana salt marshes after the BP–Deepwater Horizon oil spill
It is highlighted that heavy oil coverage on the shorelines of Louisiana marshes, already experiencing elevated retreat because of intense human activities, induced a geomorphic feedback that amplified this erosion and thereby set limits to the recovery of otherwise resilient vegetation.
Dispersion of the salt-marsh periwinkle Littoraria irrorata: Effects of water level, size, and season
This paper documents horizontal and vertical dispersion patterns of a Texas population of the saltmarsh periwinkle, Littoraria irrorata, over a 15-month period. The study was conducted within a tidal
Photo-induced toxicity of Deepwater Horizon slick oil to blue crab (Callinectes sapidus) larvae.
Findings indicate that early lifestage blue crab are sensitive to photo-induced toxicity from Deepwater Horizon slick oil, and survival was found to be UV- and PAH-dependent.
