Networks panels. For illustration purposes, we show a network example of the lowest (a), medium (b) and highest output (c) of Palm-House Efficiency (PHE) at steady state. Village landscape was maintained including palm locations. Locations of human dwellings were changed among scenarios to vary PHE. Circle and house icons symbolize palm trees and human dwellings, respectively, and the number of individuals visiting a habitat is represented by the icon’s size. The color of the connections between habitats illustrates the direction of the link (house to house: blue; palm to house: red; house to palm: yellow; and palm to palm: green) and their width is related to the flow of insect moving from an origin to a destiny patch. When the PHE is equal to zero (a) there are no connections between houses and palms. As PHE increases (b) more connections appear because houses with lights at reachable distances increase in the village. Panel c shows a simulation in which a high proportion of human dwellings are visited due to an increase in the overall network connectivity
