Comparative approaches that examine floras with similar environments, but different diversity patterns, provide good opportunities to elucidate how uneven distributions of biodiversity were assembled. eastern Asia(eA) and North America north of Mexico(NA; see definitions of eA and NA in Fig. S1 A) share similar geographical environments with comparable latitude, land area and climate,

Since their introduction in the 1960s, cochlear implants （CIS） have undergone several transformations, ulti- mately positioning themselves as the best-performing neural prosthesis available today. They have also been recognized as a unique tool for studying the potential protective effects of patterned electrical stimulation on the developing auditory system, with results from animal models often changing the manner in which CIs are used clinically to deliver auditory information to the brain （Moore and Shannon, 2009）. From the development of the first successful commercial single-channel device, they have evolved into multi-channel devices that are part of the national health programmes of several coun- tries. From the limited speech information provided by the early, rudimentary cochlear implants, these devices are now in a position to deliver intelligible speech infor- mation to the auditory system, largely due to advances in signal processing. Concerted efforts from several dis- ciplines, including engineering, acoustics, neurobiology and otolaryngology have ensured that the continued development of CI technology has resulted in signifi- cant benefits to individuals with profound sensorineural hearing loss.
