THE FULL EXPLANATIONAdaptations and recovery in fire-impacted ecosystems depend on three interacting factors: the fire regime (severity, frequency, and season), the traits species evolved under that regime, and post-fire conditions such as rainfall and seed…
THE FULL EXPLANATIONA salamander's anatomy is built around three systems no other vertebrate combines in the same way. Its skin is a living respiratory organ that handles 30 to 90 percent of gas exchange in lungless species.
