Spence https://blog.mizer.sizespectrum.org/posts/2025-04-02-age-in-mizer In this blog post, we introduce an extension that allows you to calculate dynamic growth curves and ages at size in mizer. This addition will improve how mizer is calibrated to data and also allows it to be interpreted and compared to age-based models, potentially increasing the utility of mizer in the assessment and advice process. https://blog.mizer.sizespectrum.org/posts/2025-04-02-age-in-mizer Wed, 02 Apr 2025 00:00:00 +0000 Gustav Delius https://blog.mizer.sizespectrum.org/posts/2022-12-23-mizer-240 Celebrating Christmas with a new mizer release that makes building realistic multispecies models even simpler. https://blog.mizer.sizespectrum.org/posts/2022-12-23-mizer-240 Fri, 23 Dec 2022 00:00:00 +0000 Gustav Delius https://blog.mizer.sizespectrum.org/posts/2022-11-30-dont-use-von-bertalanffy-growth-parameters Beware of the difference between age-dependent growth curves and the size-dependent growth curves used by mizer. https://blog.mizer.sizespectrum.org/posts/2022-11-30-dont-use-von-bertalanffy-growth-parameters Wed, 30 Nov 2022 00:00:00 +0000 Phoebe Woodworth-Jefcoats https://blog.mizer.sizespectrum.org/posts/2022-07-11-thermizer Temperature is an important driver of ecosystem change. Now you can include it in mizer. https://blog.mizer.sizespectrum.org/posts/2022-07-11-thermizer Mon, 11 Jul 2022 00:00:00 +0000 Gustav Delius https://blog.mizer.sizespectrum.org/posts/2021-09-07-tuning-growth-curves-with-a-shiny-gadget I present to you a new shiny gadget that makes tuning a model to reproduce the desired growth curves feel like child's play. And this is only a first glimpse of the future of interactively tuning mizer models. https://blog.mizer.sizespectrum.org/posts/2021-09-07-tuning-growth-curves-with-a-shiny-gadget Tue, 07 Sep 2021 00:00:00 +0000 Gustav Delius https://blog.mizer.sizespectrum.org/posts/2021-08-20-a-5-step-recipe-for-tuning-the-model-steady-state Getting a steady state for your mizer model that agrees with observations is in principle a hard chicken and egg problem. I present the trick that makes it surprisingly easy, with a 5-step recipe. I'll save tips on what to do when the recipe fails for later blog posts. https://blog.mizer.sizespectrum.org/posts/2021-08-20-a-5-step-recipe-for-tuning-the-model-steady-state Fri, 20 Aug 2021 00:00:00 +0000 Gustav Delius https://blog.mizer.sizespectrum.org/posts/2021-08-14-reproducible-research-with-mizer-and-binder Share your code in 5 easy steps, so that others can easily reproduce your results and build on your work. https://blog.mizer.sizespectrum.org/posts/2021-08-14-reproducible-research-with-mizer-and-binder Sat, 14 Aug 2021 00:00:00 +0000 Gustav Delius https://blog.mizer.sizespectrum.org/posts/2021-08-08-change-model-parameters-without-using Mizer provides dedicated functions for changing model parameters. Using them protects you from pitfalls arising from manipulations with the `@` symbol. https://blog.mizer.sizespectrum.org/posts/2021-08-08-change-model-parameters-without-using Sun, 08 Aug 2021 00:00:00 +0000 Gustav Delius https://blog.mizer.sizespectrum.org/posts/2021-08-03-density-dependence-in-reproduction The take-home message is that it is important to set the density dependence in your model appropriately and that with the help of the `setBevertonHolt()` function you can easily make changes to the density dependence without spoiling other aspects of your calibrated model. https://blog.mizer.sizespectrum.org/posts/2021-08-03-density-dependence-in-reproduction Tue, 03 Aug 2021 00:00:00 +0000 Gustav Delius https://blog.mizer.sizespectrum.org/posts/welcome mizer is now 9 years old. mizer is becoming more social. Time to start a blog. https://blog.mizer.sizespectrum.org/posts/welcome Sun, 01 Aug 2021 00:00:00 +0000
