Genetics and ecological speciation.
Species originate frequently by natural selection. A general mechanism by which this occurs is ecological speciation, defined as the evolution of reproductive isolation between populations as a result of ecologically-based divergent natural selection. The alternative mechanism is mutation-order speciation in which populations fix different mutations as they adapt to similar selection pressures....
متن کاملReverse Genetics in Ecological Research
By precisely manipulating the expression of individual genetic elements thought to be important for ecological performance, reverse genetics has the potential to revolutionize plant ecology. However, untested concerns about possible side-effects of the transformation technique, caused by Agrobacterium infection and tissue culture, on plant performance have stymied research by requiring onerous ...
متن کاملEcological genetics of floral evolution
The diversity of floral forms in nature can be explained largely as adaptations to the diversity of biotic and abiotic selective agents with which different plant species interact. Ecological genetics is the study of the process of adaptation, and therefore is an ideal approach to understanding floral adaptations. Here I review work on selection and genetic variance and covariance of floral tra...
متن کاملThe ecological genetics of speciation.
Ecological interactions and the natural selection they cause play a prominent causal role in biological diversification and speciation. As a discipline, ecological genetics integrates the two components of adaptive evolution (natural selection and genetic variability) to study the mechanisms of evolution. Ecological genetics is a fruitful approach to the study of how reproductive isolation can ...
متن کاملEvolutionary and Ecological Genetics of Medicago truncatula
This chapter synthesizes our current knowledge on the ecological genetics of the model legume Medicago truncatula. After a short introduction to the life cycle of the species, we describe the mating system of M truncatula and how selfing rates in nature can be inferred both by progeny testing and population surveys. We then review what is currently known on the distribution of genetic diversity...
