Low-severity fires enhance long-term carbon retention of peatlands
High-intensity fires can destroy marshy peatlands and cause them to emit huge amounts of their stored carbon into the atmosphere as greenhouse gases, but a new study finds low-severity fires spark the opposite outcome. By creating a decay-inhibiting crust on clumps of moist soil particles within the peatland, the smaller surface fires help protect the stored carbon and enhance peatlands' long-term

Research demonstrates that the characteristic zig-zag pattern on a viper's back performs opposing functions during a predation event. At first, the zig-zag pattern helps the snake remain undetected.

Most importantly the zig-zag can also produce an illusionary effect that may hide the snake's movement as it flees
