Size matters for changing ecosystems

Size Ecology Lab is an interdisciplinary ecology research group led by Associate Professor Julia Blanchard at the Institute of Marine and Antarctic Studies (IMAS), University of Tasmania.

We are a diverse team of macro- and microecologists, data analysts, mathematical modellers and socioecologists.

What we do

We work on research topics that range from fundamental ecology and evolution to more applied global ecology and sustainability.

In particular, we study the ecological role of body size and how this influences individual to ecosystem processes.

We also study the consequences of human population size and how changes in human demand and activities, coupled with environmental change, alter complex social-ecological systems.

Do you ever wake up in the morning thinking, size spectrum theory is neat, but so hard to use? Well, if you do, you are not alone! At the size ecology lab we are working on making size spectrum theory accessible and widely used which is why we build R packages (which are also neat and super easy to use). One of these R packages is called Multi-species sIZE spectrum modelling in R (mizer) and is available online for the creation of size spectrum models and project size spectra through time, but how do we even use this thing for a start?

Here at the Size Ecology Lab, we are focused on all things fishy, so we were very excited last week to see the launch of an innovative resource FishNutrients - a new tool in the already impressive suite of FishBase products. Fish are increasingly recognised as a great source of bioavailable micronutrients and long-chain fatty acids. This means they not only have a high concentration of these nutrients, but they are also in a form that humans can readily absorb.
