Marshes will take longer to recover from oil spill – MAY 14, 2019 (From Houma Today / May 14, 2019) While prior research suggested it takes a decade to recover from oil spills, scientists believe it will take a few more years for Louisiana’s marshes to recover from the Deepwater Horizon spill. Shortly after the…
Alabama researchers measured the nitrogen removal capacity of marsh sediments and compared it to sediments from subtidal unvegetated mudflats, which are what the marsh becomes when it erodes.
Researchers in Florida and Louisiana extended a Natural Resource Damage Assessment (NRDA) of fiddler crabs and periwinkle snails after the Deepwater Horizon incident to assess marsh recovery from oiling. The team found that fiddler crabs, the more mobile of the two species, had mostly recovered by 30 months in terms of size, density, and species composition.
Devika Bhalerao uses DNA analyses to identify organisms important to the larvae’s survival and determine if oiling alters the presence of various organisms in the food web. Her findings will help develop analytical tools that ecologists can use to evaluate the health of tidal marshes.
Scientists conducted a meta-analysis on marsh periwinkle snails using data spanning five years to investigate how the oil spill affected them over time. The researchers found that snails from heavily-oiled sites exhibited decreased density and shell length.
Marshes depend on a healthy, well-functioning complex of plants, microbes, and benthic communities to support the environmentally and economically important ecosystem services they offer, such as reducing storm surges and providing nursery grounds for many species.
Greenhead horse fly larvae live in Spartina marshes and are the top predator in the coastal wetlands invertebrate food chain between Texas and Nova Scotia.
As marsh plants recover from the Deepwater Horizon oil spill in Louisiana, so have the tiny plants and animals living in the soil, according to a new study published in Marine Ecology Progress Series.
It’s a catchy name. But, Marsh Madness rarely starts in March (as implied by the NCAA basketball playoffs reference) and the scientists are not crazy-mad, just crazy-busy.
No one can change history, but we can learn from it. That’s what CWC scientists are doing as they study the heavily-oiled Louisiana coastal marshes affected by the Deepwater Horizon spill.
