Welcome 🌍

I am Johannes Nauta, and I am currently a postdoctoral researcher studying networks and complex systems. I am working at the Dept. of Physics of the University of Padova in Italy.

Current research

My work aims to unravel how local (microscopic) feedback mechanisms influence global (meso- and macroscopic) dynamics of (meta)populations. More specifically, I am developing general multi-scale models that define ecological reaction-diffusion systems on networks. These models show that long-term stability can emerge from local interactions, both between competing species (reaction) and between the nodes (diffusion).

My trajectory

After obtaining my bachelor and master degrees in Nijmegen, The Netherlands, I moved to Ghent, Belgium to do my Ph.D. Early 2022, I finished my Ph.D. thesis on computational models of optimal foraging patterns. I studied the effects of intra- and interspecific interactions of foragers and focused on how the characteristics of the interaction graph influences (group-) optimal foraging behavior. I additionally studied the influence of the spatial distribution of resources on the short-term foraging efficiency and the long-term population dynamics. The latter research is in line with my current interests in ecosystem stability and function. I am currently pursuing an interdisciplinary approach on the edges of ecology, microbiology, and statistical physics, in order to unravel the mysteries behind ecosystem function. More specifically, I would like to understand the mechanisms that facilitate long-term stability of ecosystems with many constituents.

The suggestions below are works that I personally find particularly interesting. They do not contain any personal work of which I am the first author. For a list of my personal publications, please see ~/publications.

• P.L. Wennekes et al. (2012). "The neutral-niche debate: a philosophical perspective". Acta Biotheoretica, 60.
  ⤷ Philosophical perspective on the debate between niche- and dispersal-assembly. Additionally contains very interesting section on instrumentism vs. realism.

  ⤷ Very interesting work on how spatial pattern formation (such as Turing patterns) might aid complex systems to avoid tipping.

• Vitali, A. et al. (2022). "Invasive species modulate the structure and stability of a multilayer mutualistic network". bioRxiv.
  ⤷ A. Vitali and colleagues study how an invasive species can disrupt a multilayer network that contains a specific keystone interaction. They show that the invasive species reduces the connectivity between the species present in the keystone interaction and thereby increases disturbance propagation and reducing network robustness.
