  abstract = {{U}nderstanding how divergent selection generates adaptive phenotypic and population diversification provides a mechanistic explanation of speciation in recently separated species pairs. {T}owards this goal, we sought ecological gradients of divergence between the cryptic malaria vectors {A}nopheles coluzzii and {A}n.gambiae and then looked for a physiological trait that may underlie such divergence. {U}sing a large set of occurrence records and eco-geographic information, we built a distribution model to predict the predominance of the two species across their range of sympatry. {O}ur model predicts two novel gradients along which the species segregate: distance from the coastline and altitude. {A}nopheles coluzzii showed a bimodal' distribution, predominating in xeric {W}est {A}frican savannas and along the western coastal fringe of {A}frica. {T}o test whether differences in salinity tolerance underlie this habitat segregation, we assessed the acute dose-mortality response to salinity of thirty-two larval populations from {C}entral {A}frica. {I}n agreement with its coastal predominance, {A}nopheles coluzzii was overall more tolerant than {A}n.gambiae. {S}alinity tolerance of both species, however, converged in urban localities, presumably reflecting an adaptive response to osmotic stress from anthropogenic pollutants. {W}hen comparing degree of tolerance in conjunction with levels of syntopy, we found evidence of character displacement in this trait.},
