Model selection in ecology and evolution
TL;DR: The steps of model selection are outlined and several ways that it is now being implemented are highlighted, so that researchers in ecology and evolution will find a valuable alternative to traditional null hypothesis testing, especially when more than one hypothesis is plausible.
Journal ArticleDOI
Phylogeography's past, present, and future: 10 years after Avise, 2000

TL;DR: The field of phylogeography as mentioned in this paper was originally proposed by Avise and colleagues, who integrated phylogenetics and popu- lation genetics for investigating the connection between micro- and macroevolutionary phenomena.
Journal ArticleDOI
THE PACIFIC SALMON WARS: What Science Brings to the Challenge of Recovering Species
TL;DR: To deal with uncertainty, recovery teams should engage in scenario analyses in which a wide variety of assumptions are played out and there is a pressing need for analyses aimed at determining what circumstances and communication strate...
Journal ArticleDOI
Predator exposure alters female mate choice in the green swordtail
TL;DR: The hypothesis that an increase in perceived predation risk will decrease female response to males with longer swords is tested, suggesting that the female preference for males with shorter swords can be modulated based on the perceived risk of predation.
Journal ArticleDOI
Predation environment predicts divergent life-history phenotypes among populations of the livebearing fish Brachyrhaphis rhabdophora
Jerald B. Johnson,Mark C. Belk +1 more
TL;DR: It is found that the pattern of predator-associated life-history divergence in B. rhabdophora is remarkably similar to that of the taxonomically distinct Trinidadian guppy (Poecilia reticulata), possibly pointing to an evolutionary convergence between these two systems.
