 Complete the following phrase:  Phylogeography integrates biogeography and genetics to study in greater detail the lineal history of a species in context of the geoclimatic history of the planet. An example study of poison frogs living in the South American neotropics illustrated to the left is used to demonstrate how phylogeographers combine genetics and paleogeography to piece together the ecological history of organisms in their environments. Several major geoclimatic events have greatly influenced the biogeographic distribution of organisms in this area, including
