Figure 2From: Physiological correlates of ecological divergence along an urbanization gradient: differential tolerance to ammonia among molecular forms of the malaria mosquito Anopheles gambiaeDependence of ammonia tolerance, expressed by the median lethal concentration (LC 50 ), on duration of exposure to the toxicant in Anopheles gambiae molecular forms (form M: blue; form S: red). Percent figures represent the larval mortality observed in control batches of each form at different exposure intervals.Back to article page
