De Leidsche Flesch Symposium
Sneak peak of the week!
Every week we will place another abstract in this mail, so keep reading if you are interested!
On March 25th De Leidsche Flesch organises a grand symposium on the subject 'life'. Speakers from all over the Netherlands will talk about life from a fundamental perspective. Want to know more? Go to our website!
Adaptive dynamics: going from individual to population to evolutionary dynamics
Adaptive dynamics is a mathematical framework for dealing with eco-evolutionary problems, primarily based on the following simplifying assumptions: clonal reproduction, rare mutations, small mutational effects, smoothness of the demographic parameters in the traits, and well-behaved community attractors. However, often the results from adaptive dynamics models turn out to apply also under far less restrictive conditions. The main adaptive dynamics tools are its so-called canonical equation that captures how the trait value(s) currently present in the population should develop over evolutionary time, and graphical techniques for analyzing evolutionary progress for one-dimensional trait spaces like ‘pairwise invasibility plots’ and ‘trait evolution plots’. The equilibria of the canonical equation, customarily referred to as evolutionarily singular strategies, or ess-es, comprise in addition to the evolutionary equilibria, or ESSes, also points in trait space where the population comes under a selective pressure to diversify. Such points mathematically capture the ecological conditions conducive to adaptive (Darwinian) speciation.
