Earlier arriving species tend to be r-selected species, which are better dispersers, whereas later arriving species are generally K-selected species, which are better competitors.

Through Alternative Mechanisms, transfer electrons from unneeded NADH directly to ubiquinone to O2, bypassing Complexes III and IV and their proton pumps, through this process the energy in NADH is dissipated as heat.

Electrons enter the alternative respiratory pathway through the rotenone-insensitive NADH dehydrogenase, the external NADH dehydrogenase, or succinate dehydrogenase (Complex II), and pass to O2 via the cyanide-resistant alternative oxidase, energy is not conserved as ATP but is released as heat.
