-===== Project extinction risk ===== 
- 
-__Ideas (25 Jan 2013):__ 
-  * Deadline is April 2! 
-  * Main topic is climate change, adaptation, and plasticity, not necessarily evolutionary rescue 
-  * Unclear to what degree the article will be a review or a modeling paper 
-  * Need to read up recent reviews, especially Chevin 
-  * One idea: explain assumptions behind and consequences of Bürger & Lynch model 
- 
-__Moving optimum model__ 
-  * Key idea: Calculate evolutionary rates in haldanes;  
-    * choose reasonable set of genetic parameters 
-    * focus on varying ecological parameters (N, B, v, omega, theta) 
-  * Preliminary observations in small populations 
-    * Rates of evolution generally increase as the optimum pulls away 
-    * Genetic variances stay high until just before extinction; may even reach a big shortly before extinction 
-    * Initial rate of evolution low even with strong selection? Requires analysis of allele frequencies (-> standing variation project) 
-  * To do: find way to compactly visualize evolutionary rates 
-    * over which time window? 
-    * haldanes calculates over which interval? 
- 
-__Potential topics__ 
-  * Focus on evolutionary rates might be justified, since models tend to be dynamic 
-  * Phenotypic adaptation by genetic evolution: all of quantitative genetics:-), starting with breeders/Lande equation 
-  * Evolution of plasticity: been reviewed several times 
-  * Evolutionary rates: Andrew should know all about those 
-  * Maybe here our simulations fit in 
-  * Evolutionary rescue: note exactly the topic 
-  * Evolutionary rescue and plasticity: Good review in Chevin et al. 2012 
-  * Plasticity facilitates genetic adaptation: West-Eberhard etc., some more concrete models showing this to be the case 
-  * Something about the expected contribution from genetics and plasticity? Is this possible? (Ghalambor 2007) 
-  * Different kinds of environmental change (sudden, moving, fluctuating; kinds of noise) 
-  * Plasticity vs. tolerance 
-  * Constraints and limits to adaptive evolution 
-  * Costs and limits of plasticity 
-  * Evolvability <-> environmental variability 
-===== Potential PhD project on speciation ===== 
- 
-Interesting topics: 
-  * parapatric speciation 
-  * female preferences 
-  * genomic islands 
-  * mixed geographic modes 
-  * interaction between magic and non-magic traits (see van Doorn and Weissing 2004) 
-  * plasticity 
- 
-Sources of inspiration: 
-  * List of questions in Nosil book 
-  * Butlin et al review 
-  * To some degree Smadja and Butlin review 
- 
-Potential topic: Phenotypic plasticity and speciation 
-  * Reviews: Pfennig et al. 2010, Fitzpatrick 2012, Minelli & Fusco 2012 
-  * Start with more specific review about classification of scenarios and links to theory (complementary to Pfennig et al. 2010)? -- Focus on evolution of RI; classify according to types of plasticity, type of plastic traits, ... 
-  * Make a list of proposed theoretical scenarios 
-    * The clearest concepts seem to the **developmental plasticity hypothesis of speciation** and the **flexible stem hypothesis** for adaptive radiations 
-  * Make a list of proposed empirical examples 
-    * arctic charr 
-    * cichlids 
-    * flowering time 
-    * sticklebacks? 
-    * tiger salamanders? 
-    * examples from WE book 
-  * Use Thibert-Plante and Hendry (2011) as starting point (see my review on it), but focus more on evolution of female preferences? (Or use assortative mating instead?) 
-  * Some potential model ingredients/variants: 
-    * female preference vs. assortative mating 
-    * automatic vs. classic plastic magic trait 
-    * linear reaction norm vs. threshold characters 
-    * geographic setting (but two-island model seems the most natural choice) 
-    * counter-gradient variation (non-adaptive plasticity)? 
-  * Try to model the arctic charr scenario? 
-  * See list of questions in Fitzpatrick 2012 
-  * Use Draghi and Whitlock approach to model plasticity? 
-  * Plastic magic traits... 
-  * **Key question: Interaction between evolution of non-random mating and genetic assimilation** 
-  * Interaction between evolution of plastic and non-plastic barriers? 
- 
-===== Comments on Adrianna's manuscript ===== 
-  * Is this a critique of W-E's theory of speciation, or rather of her theory phenotypic evolution per se? 
-  * Describe the DPHS in more details (as in Pfennig et al. 2010, Fitzpatrick 2012)?
