Gene flow and introgression from domesticated plants into their wild relatives

Article Abstract:

Introgression from domesticated plants into their wild relatives and gene flow are discussed in this review article about the 13 most important food crops. Assessing likelihood of introgression, hybridization and potential for undesirable gene flow from crops into weeds or rare species are suggested. Most domesticated plant taxa mate with wild relatived plants sometime, someplace, and gene flow from crop taxa may be substantial impact on evolution in wild plants. Evolution of aggressive weeds and extinction of rare species are discussed. Population genetic theory is used to predict evolutionary consequences of gene flow.

Integrating function and ecology in studies of adaptation: investigations of locomotor capacity as a model system

Article Abstract:

Research into investigations of locomotor capacity as a model system is reviewed with focus on integrating function and ecology in studies of adaptation. Lizards, birds, and marine mammals are featured. It is argued that for the study of adaptation to go forward, more integration of laboratory study of performance and behavioral ecological studies is needed. How the environment affects locomotor function in nature is considered and so is what percentage of locomotor capacities animals use in nature. Widespread effects of the environment on measures of locomotor function have been shown.

The population biology of invasive species

Article Abstract:

Research into the population biology of invasive species is reviewed focusing on understanding and managing invasiveness. Opportunities for study of basic processes in population biology may be presented by invasive species. Life history studies and demographic models may help investigation of introduction of invasive species and finding life history stages at which management would be most effective. Evolutionary processes may be important factors in determining whether invasive species establish/spread.
