Newswise: Marine Seagrass Meadows Show Resilience to ‘Bounce Back’ After Die-Offs

Marine Seagrass Meadows Show Resilience to ‘Bounce Back’ After Die-Offs
Florida Atlantic University

A study in Florida Bay, one of the largest global contiguous seagrass systems, examined if a phytotoxin that accumulates as seagrass ecosystems become more enriched in nutrients prevents a marine seagrass, turtlegrass, from recruiting into open bare sediment following die-off events. While they do “bounce back,” long-term monitoring indicates the timeframe for recovery after major die-off events is at least a decade. Turtlegrass can successfully recruit into open bare sediment following die-off events due to biomass partitioning.

“Golden” fossils reveal origins of exceptional preservation
University of Texas at Austin (UT Austin)

A recent study by scientists at The University of Texas at Austin and collaborators found that many of the fossils from Germany’s Posidonia shale do not get their gleam from pyrite, commonly known as fool’s gold, which was long thought to be the source of the shine. Instead, the golden hue is from a mix of minerals that hints at the conditions in which the fossils formed.
