摘要:
Using quantitative genetic theory we develop predictions for the evolution of trade-offs in response to directional and correlational selection

摘要:
Directional selection on size is common but often fails to result in micro-evolution in the wild. Similarly, macro-evolutionary rates in size are low

摘要:
r, directional selection promoted a negative covariance between additive and maternal genetic variance over the first 10 generations. These results stress the importance
Data from: The strength of phenotypic selection in natural populations
负责人:
关键词:
natural selection;sexual selection;microevolution;natural populations;phenotypic selection
摘要:
directional selection was uncommon. The values of |?| for selection on morphological and on life-history/phenological traits were significantly different: on average
Data from: The effects of competition on the strength and softness of selection

摘要:
e effect on the average strength of selection. While the softness of selection was affected by the type of competition, the direction of change varied ac

摘要:
solution to this apparent disconnect: stabilizing selection is hard to detect empirically once populations have adapted to a fitness peak. To test
