How can we help salt marshes recover after an oil spill?

Salt marshes impacted by oil spills (like Deepwater Horizon) often experience vegetation diebacks and a loss of ecosystem function. Researchers recently found that re-establishing the dominant salt marsh vegetation, Spartina alterniflora, is critical to ensure and enhance the presence of other marsh animals. Unexpectedly, the addition of fertilizer had little to no effect on the recolonization of salt marsh critters.

Microplastics may be hitching a ride from water to land in mosquitos

Microplastics are now found all over, even in freshwater environments such as ponds, rivers and lakes. Young mosquitos live in these freshwater environments and move to land as they mature. Scientists in this study wanted to find out if young mosquitos ingest microplastics found in freshwater environments and carry the microplastics with them to air and land as adults.
