摘要: Abstract Studies of several invertebrate and vertebrate species argue for the common occurrence genetic divergence estuarine populations from conspecific in open coastal marine waters. Estuarine differentiation raises many unresolved questions: (1) Does this indicate isolation populations?; (2) Is natural selection sufficient intensity to cause divergence, despite constant influxes exports propagules estuary?; (3) What are most significant agents selection? Differences among estuaries differing salinity temperature regimes may also promote extensive differentiation. Pollutants a potentially potent among-estuary source selection. Polluted harbor animals plants with evolved tolerance pollution. This could be easily verified through broad study species' tolerances basis tolerance. The consequences such adaptations establishment environmental monitoring programs transfer pollutants up food chains deserves some reconsideration light these conclusions.
