  abstract = {{I}n this study, we use geometric morphometric method to establish morphological differences between natural populations of {N}ile tilapia from two extreme environmental conditions (high temperature and salinity) in {K}enya, and compare them to two populations from regions experiencing less extreme conditions. {T}o determine genetic influence on morphology, we correlated genetic data with morphological data. {T}he study observed significant morphological differences between all studied populations, including three closely related hot spring populations ({B}ogoria, {C}helaba and {T}urtle {S}prings), and two populations with similar genetic background inhabiting saline environments in {L}ake {T}urkana basin ({T}urkana and {C}rocodile {L}ake populations). {I}n addition, allometric growth patterns of the seven populations differed significantly, demonstrating that developmental changes (plastic or adaptive) operated between these populations. {P}ositive correlation between morphometric and genetic data confirmed the influence of genetic factors on morphology. {A}ll observed differences were attributed either to genetic and/or environmental factors, which seemed to play a major role in influencing morphology of wild {N}ile tilapia populations. {W}e recommend further studies to be carried out under controlled conditions to confirm the role of temperature, p{H} and salinity in morphological diversification of {N}ile tilapia.},
