Evolutionary Genetics: Mobile DNAs as Sources of Adaptive Change?

Evolutionary Genetics: Mobile DNAs as Sources of Adaptive Change?

Mobile DNAs are potent sources of mutation in wild populations, but seem only rarely to have been used in adaptive evolution. A new study has revealed a mobile DNA insertion in Drosophila simulans that is associated with an apparent selective sweep and an elevation in expression level of an adjacent gene which creates insecticide resistance.

Peripheral Isolates as Sources of Adaptive Diversity under Climate Change

As climate change progresses, there is increasing focus on the possibility of using targeted gene flow (TGF, the movement of pre-adapted individuals into declining populations) as a management tool. Targeted gene flow is a relatively cheap, low-risk management option, and will almost certainly come into increased use over the coming decades. Before such action can be taken, however, we need to ...

Developing Adaptive Differential Evolution as a New Evolutionary Algorithm, Application in Optimization of Chemical Processes

Adaptive evolutionary planner/navigator for mobile robots

Based on evolutionary computation (EC) concepts, we developed an adaptive Evolutionary Planner/Navigator (EP/N) as a novel approach to path planning and navigation. The EP/N is characterized by generality, exibility, and adaptability. It uni es o -line planning and on-line planning/navigation processes in the same general and exible evolutionary algorithm which (1) accommodates di erent optimiz...

Climate as a Driver of Evolutionary Change

The link between biodiversity and climate has been obvious to biologists since the work of von Humboldt in the early 1800s, but establishing the relationship of climate to ecological and evolutionary patterns is more difficult. On evolutionary timescales, climate can affect supply of energy by biotic and abiotic effects. Some of the best evidence for a link between biodiversity and climate come...
