Simulation-based approaches are a promising technique for evaluating the independent and combined effects of these factors on the outcome of various reintroduction and associated management actions.  ...  Although the importance of these factors in the success of reintroductions is well-accepted, they are typically evaluated independently, which can miss important interactions.  ...  To this end, we evaluated the role of spatial, demographic, and genetic factors in the success of reintroduction of bull trout to the lower Pend Oreille River and its tributaries.  ...

Conspecific sperm precedence is reinforced, but postcopulatory sexual selection weakened, in sympatric populations of Drosophila

Dean M. Castillo, Leonie C. Moyle
2019 Proceedings of the Royal Society of London. Biological Sciences  
This might be particularly important in the context of 'reinforcement', where selection acts directly to increase prezygotic barriers to reduce the cost of heterospecific matings.  ...  We also find these D. pseudoobscura populations have decreased sperm competitive ability against conspecifics, reducing the opportunity for sexual selection within these populations.  ...  Walburn and J.
