Show Summary Details


This chapter examines fish biogeography within the Nuclear Central America (NCA). It reviews the geologic history of the region to contextualize the processes that have generated pathways and barriers to fish diversification across this geologically complex region and summarize the forces that structured the distribution of rivers and lakes across the dynamic NCA landscape. It describes how climactic variation may have influenced the distribution of freshwater fishes across the many elevational gradients and environmentally distinct regions of NCA.

Keywords: fish biogeography; Nuclear Central America; geologic history; fish diversification; climactic variation; freshwater fishes; elevational gradients
